It includes kernel modules for enhancing the performance of virtual machines running Linux or other VMware supported Unix like guest operating systems. open-vm-tools enables the following features in VMware products: - Graceful execution of power operations (reboot and shutdown) in the guest. - Execution of built-in or user configured scripts in the guest during various power operations. - Running programs, commands and file system operations in the guest to enhance guest automation. - Authentication for guest operations. - Generation of heartbeat from guest to host for vSphere HA solution to determine guest's availabilty. - Clock synchronization between guest and host. - Quiescing guest file systems to allow host to capture file-system-consistent guest snapshot. - Execution of pre-freeze and post-thaw scripts while quiescing guest file systems. - Customization of the guest immediately after power on. - Periodic collection of network, disk, and memory usage information from the guest. - Resizing the graphical desktop screen of the guest. - Shared Folders operations between host and guest file systems on VMware Workstation and VMware Fusion. - Copying and pasting text, graphics, and files between guest and host or client desktops. - Dragging and dropping files between guest and host UI. - Periodic collection of running applications, services, and containers in the guest. - Accessing content from GuestStore. - Publishing data to Guest Data Publisher. - Managing Salt-Minion desired state specified in a guest variable. ## Can you provide more details on the actual code being released? The following components have been released as open source software: - Linux, Solaris and FreeBSD drivers for various devices and file system access. - The PowerOps plugin to perform graceful power operation and run power scripts. - The VIX plugin to run programs and commands, and perform file system operations in guest. - The GuestInfo plugin to periodically collect various statistics from guest. - The TimeSync plugin to perform time synchronization. - The dndcp plugin to support drag and drop, and text and file copy/paste operations. - The ResolutionSet plugin to adjust guest screen resolutions automatically based on window sizes. - The vmbackup plugin to support quiesced snapshot operation. - The GuestStore plugin to support GuestStore operation. - The gdp plugin to support guest data publishing operation. - The AppInfo plugin to periodically collect application information. - The ServiceDiscovery plugin to periodically collect service information. - The ContainerInfo plugin to periodically collect container information. - The ComponentMgr plugin to handle desired state operations. - The guest authentication service. - The toolbox command to perform disk wiping and shrinking, manage power scripts, and time synchronization. - The guest SDK libraries to provide information about virtual machine to guest. - Client and server for shared folders support. - Multiple monitor support. - Other utilities. ## Is open-vm-tools available with Linux distributions? Yes. open-vm-tools packages for user space components are available with new versions of major Linux distributions, and are installed as part of the OS installation in several cases. Please refer to VMware KB article http://kb.vmware.com/kb/2073803 for details. All leading Linux vendors support open-vm-tools and bundle it with their products. For information about OS compatibility for open-vm-tools, see the VMware Compatibility Guide at http://www.vmware.com/resources/compatibility Automatic installation of open-vm-tools along with the OS installation eliminates the need to separately install open-vm-tools in guests. If open-vm-tools is not installed automatically, you may be able to manually install it from the guest OS vendor's public repository. Installing open-vm-tools from the Linux vendor's repository reduces virtual machine downtime because future updates to open-vm-tools are included with the OS maintenance patches and updates. **NOTE**: Most of the Linux distributions ship two or more open-vm-tools packages. "open-vm-tools" is the core package without any dependencies on X libraries and "open-vm-tools-desktop" is an additional package with dependencies on "open-vm-tools" core package and X libraries. The "open-vm-tools-sdmp" package contains a plugin for Service Discovery. There may be additional packages, please refer to the documentation of the OS vendor. Note that the open-vm-tools packages available with Linux distributions do not include Linux drivers because Linux drivers are available as part of Linux kernel itself. Linux kernel versions 3.10 and later include all of the Linux drivers present in open-vm-tools except the vmhgfs driver. The vmhgfs driver was required for enabling shared folders feature, but is superseded by vmhgfs-fuse which does not require a kernel driver. ## Will there be continued support for VMware Tools and OSP? VMware Tools will continue to be available under a commercial license. It is recommended that open-vm-tools be used for the Linux distributions where open-vm-tools is available. VMware will not provide OSPs for operating systems where open-vm-tools is available. ## How does this benefit other open source projects? Under the terms of the GPL, open source community members are able to use the open-vm-tools code to develop their own applications, extend it, and contribute to the community. They can also incorporate some or all of the code into their projects, provided they comply with the terms of the GPL. # License Related ## What license is the code being released under? The code is being released under GPL v2 and GPL v2 compatible licenses. To be more specific, the Linux kernel modules are being released under the GPL v2, while almost all of the user level components are being released under the LGPL v2.1. The SVGA and mouse drivers have been available under the X11 license for quite some time. There are certain third party components released under BSD style licenses, to which VMware has in some cases contributed, and will continue to distribute with open-vm-tools. ## Why did you choose these licenses? We chose the GPL v2 for the kernel components to be consistent with the Linux kernel's license. We chose the LGPL v2.1 for the user level components because some of the code is implemented as shared libraries and we do not wish to restrict proprietary code from linking against those libraries. For consistency, we decided to license the rest of the userlevel code under the LGPL v2.1 as well. ## What are the obligations that the license(s) impose? Each of these licenses have different obligations. For questions about the GPL, LGPL licenses, the Free Software Foundation's GPL FAQ page provides lots of useful information. For questions about the other licenses like the X11, BSD licenses, the Open Source Initiative has numerous useful resources including mailing lists. The Software Freedom Law Center provides legal expertise and consulting for free and open source software (FOSS) developers. ## Can I use all or part of this code in my proprietary software? Do I have to release the source code if I do? Different open source licenses have different requirements regarding the release of source code. Since the code is being released under various open source licenses, you will need to comply with the terms of the corresponding licenses. ## Am I required to contribute back any changes I make to the code? No, you aren't required to contribute any changes that you make back to the open-vm-tools project. However, we encourage you to do so. ## Can I use all or part of this code in another open source package? Yes, as long as you comply with the appropriate license(s). ## Can I package this for my favorite operating system? Yes! Please do. ## Will the commercial version (VMware Tools) differ from the open source version (open-vm-tools)? If so, how? Our goal is to work towards making the open source version as close to the commercial version as possible. However, we do currently make use of certain components licensed from third parties as well as components from other VMware products which are only available in binary form. ## If I use the code from the open-vm-tools project in my project/product, can I call my project/product VMware Tools? No, since your project/product is not a VMware project/product. # Building open-vm-tools ## How do I build open-vm-tools? open-vm-tools uses the GNU Automake tool for generating Makefiles to build all sources. More information about Automake can be found here: http://www.gnu.org/software/automake/ ## Project build information: The following steps will work on most recent Linux distributions: ``` autoreconf -i ./configure make sudo make install sudo ldconfig ``` ### Service Discovery (sdmp) plugin To build the optional sdmp (Service Discovery) plugin use the `--enable-servicediscovery` option to invoke the configure script: ``` ./configure --enable-servicediscovery ``` ### The open-vm-tools 12.0.0 release introduces an optional setup script and two plugins (one optional) * Salt Minion Setup * Component Manager plugin * ContainerInfo plugin (optional) ### Salt Minion Setup The Salt support on Linux consists of a single bash script to setup Salt Minion on VMware virtual machines. The script requires the "curl" and "awk" commands to be available on the system. Linux providers supplying open-vm-tools packages are recommended to provide Salt Minion support in a separate optional package - "open-vm-tools-salt-minion". To include the Salt Minion Setup in the open-vm-tools build use the `--enable-salt-minion` option when invoking the configure script. ``` ./configure --enable-salt-minion ``` ### Component Manager (componentMgr) plugin The component Manager manages a preconfigured set of components available from VMware that can be made available on the Linux guest. Currently the only component that can be managed is the Salt Minion Setup. ### ContainerInfo (containerInfo) plugin The optional containerInfo plugin retrieves a list of the containers running on a Linux guest and publishes the list to the guest variable "**guestinfo.vmtools.containerinfo**" in JSON format. The containerInfo plugin communicates with the containerd daemon using gRPC to retrieve the desired information. For containers that are managed by Docker, the plugin uses libcurl to communicate with the Docker daemon and get the names of the containers. Since this plugin requires additional build and runtime dependencies, Linux vendors are recommended to release it in a separate, optional package - "open-vm-tools-containerinfo". This avoids unnecessary dependencies for customers not using the feature. #### Canonical, Debian, Ubuntu Linux | Build Dependencies | Runtime | |:------------------------:|:----------------:| | `libcurl4-openssl-dev` | `curl` | | `protobuf-compiler` | `protobuf` | | `libprotobuf-dev` | `grpc++` | | `protobuf-compiler-grpc` | | `libgrpc++-dev` | | `golang-github-containerd-containerd-dev` | | `golang-github-gogo-protobuf-dev` | #### Fedora, Red Hat Enterprise Linux, ... | Build Dependencies | Runtime | |:------------------------:|:----------------:| | `libcurl-devel` | `curl` | | `protobuf-compiler` | `protobuf` | | `protobuf-devel` | `grpc-cpp` | | `grpc-plugins` | | `grpc-devel` | | `containerd-devel` | #### Configuring the build for the ContainerInfo plugin The configure script defaults to building the ContainerInfo when all the needed dependencies are available. ContainerInfo will not be built if there are missing dependencies. Invoke the configure script with `--enable-containerinfo=no` to explicitly inhibit building the plugin. ``` ./configure --enable-containerinfo=no ``` If the configure script is given the option `--enable-containerinfo=yes` and any necessary dependency is not available, the configure script will terminate with an error. ``` ./configure --enable-containerinfo=yes ``` ## Getting configure options and help If you are looking for help or additional settings for the building of this project, the following configure command will display a list of help options: ``` ./configure --help ``` When using configure in the steps above it is only necessary to call ./configure once unless there was a problem after the first invocation. # Getting Involved ## How can I get involved today? You can get involved today in several different ways: - Start using open-vm-tools today and give us feedback. - Suggest feature enhancements. - Identify and submit bugs under issues section: https://github.com/vmware/open-vm-tools/issues - Start porting the code to other operating systems. Here is the list of operating systems with open-vm-tools: * Red Hat Enterprise Linux 7.0 and later releases * SUSE Linux Enterprise 12 and later releases * Ubuntu 14.04 and later releases * CentOS 7 and later releases * Debian 7.x and later releases * Oracle Linux 7 and later * Fedora 19 and later releases * openSUSE 11.x and later releases * Flatcar Container Linux, all releases * Rocky 8 and later releases * AlmaLinux OS 8 and later releases ## Will external developers be allowed to become committers to the project? Yes. Initially, VMware engineers will be the only committers. As we roll out our development infrastructure, we will be looking to add external committers to the project as well. ## How can I submit code changes like bug fixes, patches, new features to the project? Initially, you can submit bug fixes, patches and new features to the project development mailing list as attachments to emails or bug reports. To contribute source code, you will need to fill out a contribution agreement form as part of the submission process. We will have more details on this process shortly. ## What is the governance model for managing this as an open source project? The feature roadmap and schedules for the open-vm-tools project will continue to be defined by VMware. Initially, VMware engineers will be the only approved committers. We will review incoming submissions for suitability for merging into the project. We will be looking to add community committers to the project based on their demonstrated contributions to the project. Finally, we also plan to set up a process for enhancement proposals, establishing sub-projects and so on. ## Will you ship code that I contribute with VMware products? If so, will I get credit for my contributions? Contributions that are accepted into the open-vm-tools project's main source tree will likely be a part of VMware Tools. We also recognize the value of attribution and value your contributions. Consequently, we will acknowledge contributions from the community that are distributed with VMware's products. ## Do I need to sign something before making a contribution? Yes. We have a standard contribution agreement that covers all contributions made to the project. It gives VMware and you joint copyright interests in the code you are contributing. The agreement also gives VMware flexibility with licensing and also helps avoid any copyright/licensing related issues that may arise in the future. In order for us to include your contribution in our source tree, we ask that you send us a signed copy of the agreement. You can do this in one of two ways: Fax to +1.650.427.5003, Attn: Product & Technology Law Group Scan and email it to oss-queries_at_vmware.com Agreement: http://open-vm-tools.sourceforge.net/files/vca.pdf ## My version of Linux is not recognized. How do I add my Linux name to the known list? The open-vm-tools source contains a table mapping the guest distro name to the officially recognized short name. __Please do not submit pull requests altering this table and associated code.__ Any changes here must be accompanied by additional changes in the VMware host. Values that are not recognized by the VMware host will be ignored. Use the appropriate generic Linux designation when configuring a VM for your Linux version. The selection available will vary by virtual hardware version being used. - Other 5.x or later Linux (64-bit) - Other 5.x or later Linux (32-bit) - Other 4.x Linux (64-bit) - Other 4.x Linux (32-bit) - Other 3.x Linux (64-bit) - Other 3.x Linux (32-bit) - Other Linux (64-bit) - Other Linux (32-bit) # Compatibilty ## What Operating Systems are supported for customization?

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! open-vm-tools-stable-12.5.0/open-vm-tools/ChangeLog000066400000000000000000016655141470176644300221150ustar00rootroot00000000000000commit 05afe0ae703d6027325059876528fe3b04fdf386 Author: Kruti Date: Thu Oct 10 06:12:07 2024 -0700 ================================================= open-vm-tools 12.5.0 released at this point. ================================================= Update of the ChangeLog with the final changes in preparation for the open-vm-tools 12.5.0 release. commit ef2095ffda17a766a65bf39d61f4cdb9c735fa62 Author: Kruti Date: Wed Oct 9 20:49:01 2024 -0700 Update the ReleaseNotes.md for the 12.5.0 open-vm-tools release. commit 96094bb1a59c67af99d31d5acfdc731f14109e47 Author: Kruti Date: Wed Oct 9 19:47:45 2024 -0700 Prepare for the open-vm-tools 12.5.0 release. - Update the tools version in the configure.ac. - Update the build numbers in the buldNumber.h. commit 412a4b1db38627062a8ebb955b0d483edee0a1ff Author: Kruti Date: Thu Oct 3 23:34:31 2024 -0700 Update ChangeLog with the granular push of Oct 03, 2024. - plus copyright update - plus ChangeLog update of Sep 24, 2024. commit e54a2d61657e3c4c0fd4299cc5c830b4263e27bd Author: Kruti Date: Thu Oct 3 23:17:34 2024 -0700 Correct missed 2024 copyright update. commit a2ff5f28720eca493c5369448b48d1ad595e368b Author: Kruti Date: Thu Oct 3 22:57:50 2024 -0700 open-vm-tools l10n message updates commit a240f6a1d75c4fbacb1e9364ff48dfce304a23dc Author: Kruti Date: Thu Oct 3 22:57:50 2024 -0700 Ignore deprecated warning for LIBXML2 APIs xmlFileXXX.

The issue happens on vrops node VMs that are part of large clusters because these kind of nodes typically have a large amount of tcp/udp connections. The root cause of the issue is an enormous number of spaces generated by "ss -antup | grep -E $pattern" command in get-connection-info.sh. The SDMP plugin considers these spaces while calculating the chunk size for writing into NDB and writing about 200-400 chunks for the get-connection-info key. Processing of this amount of data slows down the discovery process on both the adapter and plugin sides and, as a result, the discovery exceeds the timing limit and fails. The solution is to remove unnecessary spaces from the end of the get-connection-info output lines. commit fa6d75da8c15c7fb3a696839c9f4aa7b43344d31 Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Change to common source file not applicable to open-vm-tools at this time. commit 5681e42c30f9a8875abfcdecb8c12ee8c51416f1 Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Record the use of version 12.4.5 in the vm_tools_version.h header commit 200fa56ef5f0097df888c34e24cb52c9c947d287 Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Fixes for issues found in Coverity scan. vgauth/serviceImpl/saml-xmlsec1.c issue: 'string_null' for strlen(pemCert) impact: False-positive fix: suppress 'string_null' issue: leaked_storage: certChain is not cleaned up on error. impact: Memory is leaked on the error path. fix: Add line before return to free certChain. vgauth/common/i18n.c issue: 'leaked_storage' for "name" variable impact: False-positive fix: suppress 'leaked_storage' lib/file/file.c issue: use_after_free for 'src' pointer impact: False-positive fix: suppress 'use_after_free' services/plugins/serviceDiscovery/serviceDiscovery.c issue: overrun-local: gdpErrMsgs array contains one less entry then there are enum defined. impact: Valid but the function never return the GDP_ERR_MAX enum. fix: in gdp.h, add an error entry for GDP_ERR_MAX this way gdpErrMsgs will generate all entries. lib/file/fileLockPosix.c issue: string_null for 'buffer' not being null terminated. impact: False-positive fix: suppress 'string_null' commit 1963bfed9f388aa57c9a8fc5d0f17424c76cbe60 Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Change to common header file not applicable to open-vm-tools. commit 1d19761e81b9a601b6fdb10109c92331f0b11eef Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Change to common header file not applicable to open-vm-tools. commit 5c10fab774d061230e8e747569d918272b182366 Author: Kruti Date: Fri May 3 09:05:45 2024 -0700 Fix the SHELLCHECK_WARNING findings from static application security testing (SAST) install/Linux/scripts/network: Multiple shellcheck issues found in the Linux "network" script with the warning "Remove backticks to avoid executing output (or use eval if intentional)."

The Service Discovery plugin was updated for API compatibility. Changes in the GDP protocol/handshake introduce versioning of the protocol. The new version is “2” and introduces new attributes (‘version’ and ‘requireSubs’) in the guest request header sent to the host publisher service. The response from the host publisher service to the guest producer client is also versioned and changes more significantly: V2 response messages have new attributes (‘version’, ‘error-id’, and ‘error-text’) and have the ‘status’ attributes type change from string (‘ok’, ‘bad’) to Boolean (‘true’, ‘false’). The ‘error-id’, when present, contains a string identifier for an error type/code and ‘error-text’, when present, contains textual details for the error. The host publisher supports all protocol versions up to the version it provides for backward and forward compatibility. The host publisher service responds with the same version of protocol as the incoming request or its highest protocol version when the incoming request version is higher than it supports. The guest producer client supports all response versions up to the version it provides for backward and forward compatibility. The guest producer client always sends request to the host publisher service using the highest protocol version it supports. commit c7c88a4aacd05f7d6f232c11c5537f2d43934d6b Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit 7800de416d88ba03db4f8bd818d7c99d51048bdf Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common source file not applicable to open-vm-tools. commit 72effb954333e49657315835c4df87fc0417ad2a Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit 14ada379295c86b9eed8d407753c88610312a6e8 Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit 2683d53f2ef4e8e01c938b6ec81f87e46e187c3d Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit 8f03cddae70d27fe10b2833d53995f1dd3985f37 Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit 77f6b260876aba27c497a96c833b26ec5d50578a Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit f76fea45d2c4de6ebcc0d7f5ed40a6c24689abef Author: Katy Feng Date: Thu Nov 16 09:21:20 2023 -0800 Change to common header file not applicable to open-vm-tools. commit f756d77a51c5e1c7d66b46e5e33774b5503e21de Author: Katy Feng Date: Mon Nov 13 13:14:45 2023 -0800 Update Changelog with the granular push of Nov. 13, 2023. - plus ChangeLog update of Oct. 5, 2023. commit 8647f0cf7a15f1c3a06e903cb15e053871d23c36 Author: Katy Feng Date: Mon Nov 13 12:07:34 2023 -0800 Change to common header file not applicable to open-vm-tools. commit beb027f7eccea977d00ef2a91da29e19ccc0a6d8 Author: Katy Feng Date: Mon Nov 13 12:07:34 2023 -0800 Change to common header file not applicable to open-vm-tools. commit e7c2898e1a2b61948efd7bfd582a36a0e9363b3b Author: Katy Feng Date: Mon Nov 13 12:07:34 2023 -0800 Guest identification: Asianux Linux is now Miracle Linux The Asianux distro rebranded itself as Miracle Linux.

Now vmtoolsd is not executed with dropped privileges (started as setuid program) and the dumpable attribute of the process is not reset. Unprivileged users will not have access to the privileged file descriptors in the vmtoolsd vmusr process. Also, set the FD_CLOEXEC flag for both uinputFd and blockFd preventing those file descriptors from being inherited any further from vmtoolsd. commit fd4c58055253ba80d84a17778d9f2e93d117350e Author: Katy Feng Date: Mon Nov 13 12:07:34 2023 -0800 Don't accept tokens with unrelated certs If a SAML token has a cert that's not a part of a chain, fail the token as invalid. commit 0546037841f16e8fe4148c8434e2b02cb2b0a6dd Author: Katy Feng Date: Mon Nov 13 12:07:34 2023 -0800 Change to common header file not applicable to open-vm-tools. commit c10d8436ff4137dbd66b17d12ffe1be7e00a1f2d Author: Katy Feng Date: Mon Nov 13 12:07:33 2023 -0800 Change to common header file not applicable to open-vm-tools. commit cdbc0b2bee9d771ab3c3312abe737cabecf4bfc8 Author: Katy Feng Date: Mon Nov 13 12:07:33 2023 -0800 Change to common header file not applicable to open-vm-tools. commit fa2b47d9a4d0f27be5a5172c5d0eb6f197fca596 Author: Katy Feng Date: Mon Nov 13 12:07:33 2023 -0800 Change to common header file not applicable to open-vm-tools. commit e9cab85bc079a3b5b0cc9f154a0aa90946314c72 Author: Katy Feng Date: Mon Nov 13 12:07:33 2023 -0800 Change to common header file not applicable to open-vm-tools. commit fdb122f3e196835e97d2828fd77580d4f7bedb1a Author: Katy Feng Date: Mon Nov 13 12:07:33 2023 -0800 Suppress optional arg to backup scripts when empty string.

Instead, keep local settings, such as this flag, in config files under the /etc/cloud/cloud.cfg.d directory, for example: /etc/cloud/cloud.cfg.d/somefile.cfg This change implements the following adjustments to make sure this flag is handled the same way as cloud-init does in ds-identify and Datasource: 1. Instead of regex matching flag 'disable_vmware_customization: false', check the value of flag 'disable_vmware_customization': If the value is 'false', it means VMware customization is enabled. If the value is 'true', it means VMware customization is disabled. If the flag is not set, by default VMware customization is disabled on cloud-init side. 2. Besides cloud-init /etc/cloud/cloud.cfg file, also check all .cfg files under /etc/cloud/cloud.cfg.d directory. 3. The value of flag 'disable_vmware_customization' in .cfg files under /etc/cloud/cloud.cfg.d directory will overwrite the one in the /etc/cloud/cloud.cfg file. 4. The value of flag 'disable_vmware_customization' in a .cfg file listed further down in alphabetical order under the /etc/cloud/cloud.cfg.d directory will overwrite the value in a .cfg file listed earier. 5. If a cloud-init config file contains more than one instance of this flag, the value of the later flag will overwrite the former one.

Effective with open-vm-tools 12.2.0, Linux quiesced snapshots will fail if any filesystem(s) have been prefrozen by other than the vmtoolsd process. This has been done to assure that filesystems are inactive while the snapshots are being taken. Some existing prefreeze scripts may be freezing some filesystem(s). In these cases, the vmtoolsd process must be informed of anticipated pre-frozen filesystems by providing an "excludedFileSystem" list in the [vmbackup] section of the tools.conf file. This change provides a new switch in the tools.conf file to allow pre-frozen filesystems to be encountered and accepted when doing a quiesced snapshot operation. With the default value of "false", the "ignoreFrozenFileSystems" can be configured with a setting of "true" to notify the quiesced snapshot operation that pre-frozen filesystems are allowed. commit baf812a3d942e9f1a6fe9774ddc5e514b976f059 Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common header file not applicable to open-vm-tools. commit b3c23d050ffab46ae24d6fc8e98851a07863dd2a Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 99ee819329e6b1b51affcf15673c2020bfe4e059 Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common header file not applicable to open-vm-tools. commit dcc090563d12ba436c7137bb3861b2966fc372cd Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common source file not applicable to open-vm-tools. commit c0116f300bfe2d37919fb333d63fd401dc228e5b Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 3f4dd03d969efe60c6c77002a3b8c8ddfd325ab3 Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common source file not applicable to open-vm-tools. commit 6aa05e8959408d0981c18ed8dfc29513b71c98a8 Author: Katy Feng Date: Tue Aug 22 11:11:42 2023 -0700 Change to common header file not applicable to open-vm-tools. commit f6c27bbe691ba06f535d9b5d5dbabd4d4d5e3b1b Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 01d4788e191d1a846dbe7220442e25bba2cb545c Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 9d8054800e10cabeed6911a5b8ac85d612565fe6 Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 0bc0f8e68339c1bae63e9d8734d4d10c8d4b5fa9 Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 549f04fabbba57a33b8983e02064e216b8393485 Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Changes to common header files not applicable to open-vm-tools. commit 508933ad4fb97cde6d19544d13005c88eaa9362f Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 9f1c97526ba6414bfbc342fcf0f8a83118dbee8d Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 016fa52e6bcbf868a08b5dbac0fdb8f19ab14c9a Author: Katy Feng Date: Tue Aug 22 11:11:41 2023 -0700 Removing appUtil library from open-vm-tools.

Instead, they rely exclusively on the the os-release standard information. We previously used a ranking system that rates the LSB data (if present) against the os-release data (if present). With the LSB data install much more rare than before, perform a quick check for the LSB before attempting expensive operations. This is in response to these GitHub issues: https://github.com/vmware/open-vm-tools/issues/647 https://github.com/vmware/open-vm-tools/issues/648 Note that we cannot look just for the os-release data. In older Linux releases, there are mistakes or differences between the os-release and LSB data. We must continue to do what we do now or risk changing the identification of older releases. This optimization is very effective. commit b9da6af8a561b911c6d59cfffb5b96cd5af3b6f7 Author: Katy Feng Date: Fri Mar 24 13:48:17 2023 -0700 Update ChangeLog with the granular push of Mar 24, 2023. - plus ChangeLog update of Mar 6, 2023. commit dfe0aa7ef53ea6051d31cc69f406e746e8d0f80c Author: Katy Feng Date: Fri Mar 24 13:29:28 2023 -0700 Change to common source file not applicable to open-vm-tools. commit 5e28e7e7577b35c585d4c45e053a162615bdbb1b Author: Katy Feng Date: Fri Mar 24 13:29:28 2023 -0700 Change to common header file not applicable to open-vm-tools. commit 2a9a730985ff05bcb808e68e4526856bb77a4c17 Author: Katy Feng Date: Fri Mar 24 13:29:28 2023 -0700 Change to common header file not applicable to open-vm-tools. commit acff74d7fa4e4f3bb70c575a287cac2762cfdaec Author: Katy Feng Date: Fri Mar 24 13:29:28 2023 -0700 Record the usage of VMware Tools version 12.2.5 in vm_tools_version.h Adding tools TOOLS_VERSION_BANDSAW_UPDATE1 for 12.2.5 into the vm_tools_version.h header file. commit c30e8e66dcc41fd6e869c3a87d712ab29a90df8a Author: Katy Feng Date: Fri Mar 24 13:29:28 2023 -0700 Record the GA release of VMware Tools 12.2.0.

An EBUSY could be seen because of an attempt to freeze the same superblock more than once depending on the OS configuration (e.g. usage of bind mounts). An EBUSY could also mean another process has locked or frozen that filesystem. When an EBUSY is received, the filesyste FSID is checked against the list of filesystems that have already be quiesced. If not previously seen, a warning that the filesystem is controlled by another process is logged and the quiesced snapshot request will be rejected. commit 193200d3ce31461f876f4779ced3ca5c85f32459 Author: Katy Feng Date: Tue Jan 17 19:08:33 2023 -0800 Salt-Minion 1.4 copyright and license updates. commit c3d2d7a23ad0deac57bf53667ebe5d14c24d53c2 Author: Katy Feng Date: Tue Jan 17 19:08:33 2023 -0800 Change to common header file not applicable to open-vm-tools. commit ebd466b5a4f55e68486cc0e747ee6b76a4f171f1 Author: Katy Feng Date: Tue Jan 17 19:08:33 2023 -0800 backdoor_def.h: Update the Arm specific comment to be arm64 only. commit 998ff379939defc09834ae55fea450ee61f46ca9 Author: Katy Feng Date: Tue Jan 17 19:08:33 2023 -0800 FreeBSD: Support newer releases and code clean-up for earlier versions.

Previous changes laid foundation to subscribe and unsubscribe for TimeInfo updates in open-vm-tools during init/shutdown. When open-vm-tools subscribes for TimeInfo updates, VMX will send a notification GuestRPC to tools if and when the timing properties change. This change adds support to handle such GuestRPCs from VMX. The handler for the GuestRPC is pretty straightforward for now: it queues an async task that simply gets all updates and logs them. commit 4ab39d04ddde473a9698660a545c356aa5614dcb Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 Change to common header file not applicable to open-vm-tools. commit 0b2992f6718150d7c04ce4268e071033d4222e45 Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 Limit retry if the VMX RESETs a vsock connection If guest_rpc.rpci.usevsocket = "FALSE" is set, a vsock connect() will always fail with RESET.

Limit retry, and only for secure connections. commit 3cfb89bd45978bababef56404e33da7e645b0b5a Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 [TimeInfo] Subscribe/unsubscribe to notifications during init/shutdown This change adds support for subscribing to time info notifications when this feature is enabled in the tools. As a result VMX will send time info notifications to the tools when host timing properties change. The change adds support to perform subscribe/ unsubscribe GuestRPCs from tools. Note that, handling of notification (received from VMX) will be implemented in the next change. commit a23ac6dc590374f3b990f4d220ec59d1c3d82195 Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 Change to common header file not applicable to open-vm-tools. commit 70c64efdedfc4b6772fe540f502113b8b58d6aad Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 Change to common header file not applicable to open-vm-tools. commit 11d8bddccab30dea8c33ab8fb895b599ea6b8419 Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 Change to common header file not applicable to open-vm-tools. commit 4e5ff11a5927ebf711656d30166914725fd811f9 Author: Katy Feng Date: Thu Dec 22 16:25:50 2022 -0800 [TimeInfo] Introduce TimeInfo in TimeSync plugin This change lays a foundation for upcoming changes to support TimeInfo feature in open-vm-tools. TimeInfo feature is introduced as part of TimeSync plugin and can be used to query, set, subscribe, and receive updates for time-related information from the host when guest is using precisionclock to consume time from the host. This change simply adds a new file and basic init/shutdown routines which are called as part of TimeSync plugin load/unload. The change also introduces a config option to enable/disable this feature (default is off). The feature is Linux-only for now.

Add comments for two memory leak false positives reported by a Coverity scan of open-vm-tools. Don't annotate since the annotations can't be made specified to the leaked variable, so that if an actual leak were introduced in the future an annotation would cause it to be reported as a false positive. For the same reason, replace a leaked storage annotation added previously with an explanatory comment. commit b85ab7a63a97d9b7258df73638c76f9b7c149a4f Author: John Wolfe Date: Fri Nov 4 11:45:05 2022 -0700 Change to common header file not applicable to open-vm-tools. commit da618bbbdaa6341c478d548a7d951250c571ad8e Author: John Wolfe Date: Fri Nov 4 11:45:05 2022 -0700 Changes to common source files not applicable to open-vm-tools. commit f5eb126149dccb3172a90e772f6d5471a6c2c435 Author: John Wolfe Date: Fri Nov 4 11:45:05 2022 -0700 Change to common source file not applicable to open-vm-tools. commit d88dcf561315a316c1e2efda6a96ec22e2183306 Author: John Wolfe Date: Fri Oct 21 12:11:07 2022 -0700 Update ChangeLog with the granular push of Oct 21, 2022. - plus ChangeLog update of Oct 12, 2022. commit 3e1154b1e260982a47f66a9c807b7613ced95f59 Author: John Wolfe Date: Fri Oct 21 11:39:49 2022 -0700 Common header file change not applicable to open-vm-tools. commit 6d934775155d5b1ee000056319290780e4e79b80 Author: John Wolfe Date: Fri Oct 21 11:39:49 2022 -0700 Fix a regression caused by the previous guestOps ListFiles() change.

When open-vm-tools comes preinstalled in a base Linux release, the vmtoolsd services are started automatically at system start and desktop login. If running on physical hardware or in a non-VMware hypervisor, the services will emit an error message to the systemd's logging service before stopping. This change removes the unwanted error message. commit c1ba736f18d35d5b1e149aa43a902cb2a69927f3 Author: John Wolfe Date: Fri Oct 21 11:39:49 2022 -0700 Common header file change not applicable to open-vm-tools. commit 6224a7616e26fd816772a82e100674ffdd87cf9f Author: John Wolfe Date: Fri Oct 21 11:39:49 2022 -0700 Common header file change not applicable to open-vm-tools. commit 6ec06e4a6482872421a87367814849f340bfb1a8 Author: John Wolfe Date: Wed Oct 12 13:21:25 2022 -0700 Update ChangeLog with the granular push of Oct 12, 2022. - plus ChangeLog update of Sep 21, 2022. commit 7909b89d2d847f416257932e3c6ef96085a69ad4 Author: John Wolfe Date: Wed Oct 12 13:04:00 2022 -0700 Add missed 2022 copyright change. commit cb762155088e5f56535d1f8990718d8880d165ff Author: John Wolfe Date: Wed Oct 12 12:40:37 2022 -0700 Common header file change not applicable to open-vm-tools. commit 51a5cca0c77ea4f246e5a411727221fcf70f240e Author: John Wolfe Date: Wed Oct 12 12:40:37 2022 -0700 Common header file change not applicable to open-vm-tools. commit 70a10365ba86e871710551d54e565ba6b8b3f4eb Author: John Wolfe Date: Wed Oct 12 12:40:37 2022 -0700 Common header file change not applicable to open-vm-tools. commit 7645e6cd7e3e8f13a862ce3489ea04bad3a26bf2 Author: John Wolfe Date: Wed Oct 12 12:40:37 2022 -0700 Update the guestOps to handle some edge cases.

If a snapshot operation times out, vmbackup can attempt to undo quiescing. Since no quiescing is done for the null backup provider, no undo function was provided. If vmbackup attempts to call the undo function, it dereferences a garbage pointer resulting in a segfault. Rather than add null backup provider specific checks to vmbackup, this change adds a null undo function to provide vmbackup with a valid function pointer it can call. The new undo function updates the vmbackup state machine state with a new currentOpName, but has no other effect. currentOpName is set to the calling function name, e.g. __FUNCTION__. commit 42437c1131ee990737986d3fd5248bd17ec3e5ff Author: John Wolfe Date: Tue Sep 13 10:31:15 2022 -0700 Change to common header file not applicable to open-vm-tools. commit f1e30c3cb3b698a91de4966206350df2e08be128 Author: John Wolfe Date: Tue Sep 13 10:31:15 2022 -0700 Changes to common source files not applicable to open-vm-tools. commit 484ab8d8443ac6dd42f2ba7aabae4a7b44eda2e3 Author: John Wolfe Date: Tue Sep 13 10:31:15 2022 -0700 Common header file change not applicable to open-vm-tools. commit 8b98bd41def988342c16a870a4e7e880885dc81d Author: John Wolfe Date: Tue Sep 13 10:31:15 2022 -0700 Common header file change not applicable to open-vm-tools. commit 6d0cf2442fb9ec26be9528952e871c35019a1854 Author: John Wolfe Date: Tue Sep 13 10:31:15 2022 -0700 Common header file change not applicable to open-vm-tools. commit 064033a0ea74599d93f2a9988e0331efbe8f981f Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 [deployPkg] Increase the maximum timeout for cloud-init execution to complete. commit f3979ace5779c481073004968d6d9787d24c1096 Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 Record the use of VMware Tools version 10.3.26 in vm_tools_version.h Tracking the use of 10.3.26 for TOOLS_VERSION_JACKHAMMER_PATCH13. commit 22f7f76e19c906890f5cd35bde1a43ae90e77f79 Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 Make Linux perl based customization work with the cloud-init workflow. To resolve issues seen where users want to set a vm's networking and apply cloud-init userdata together before the vm is booted, the deployPkg plugin has been modified to wait for cloud-init execution to finish. This allows cloud-init to finish execution completely before the customization process triggers a reboot of the guest. This change is solely in the deployPkg plugin side, so a user can get this change by upgrading their open-vm-tools in the guest/template. commit 15e8c9828bcef3eb41e7655b0f18c575dc495b25 Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 Common header file change not applicable to open-vm-tools. commit a2cb7be60dbaa2b632872b37e187570a92fe6b2a Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 Common header file change not applicable to open-vm-tools. commit 1dbbb6e91e5388a88fe063d61d0cbb9602fb75a1 Author: John Wolfe Date: Tue Sep 13 10:31:14 2022 -0700 Address Coverity issues. base64.c - buffer overrun (out); false positive hashTable.c - expression always false; false positive commit 587be32ec29a3665e30f7509d3d3c8f8ada505e7 Author: John Wolfe Date: Thu Sep 8 14:57:36 2022 -0700 Update ChangeLog with the granular push of Sep 8, 2022. - plus ChangeLog update of Aug 21, 2022. commit 29b92ada5842c2b9d1cde7dbc9dafb69d6a18b96 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Change to common source file not applicable to open-vm-tools. commit 775671dc79aa47d82df2ad43e63e18d215625510 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Common header file change not applicable to open-vm-tools. commit 95b78cf63ea7dc37b6d9bd5b0f37cd074359ed0f Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Changes to common header files not applicable to open-vm-tools. commit 8fa7eef2d27971753d9d6d1dd4fd5bd1a7a3dd17 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 [dnd] Coverity Fixes dndCommon.c - truncating time value; false positive commit 900e24d53bca579d8ad6b12687daf670fb7fe5a6 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 [asyncsocket] Coverity Fixes asyncsocket.c - dereferencing null pointer (asock); false positive. commit 8aa0bc98bf2986b47800dd7eaf544e7e800a075e Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Change to common header file not applicable to open-vm-tools. commit d3a4f33d29db6050ca84f504c9d3a557484e4a7d Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Common header file change not applicable to open-vm=tools. commit bdca47456a592040474b21ad0db40f820dcc87f9 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Common header file change not applicable to open-vm-tools. commit 2875dd33aa494879103b9bf6a635781a99c1292a Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 lib/rpcin/rpcin.c: Address issues reported by Coverity. commit bbf4831bcfdb90428dae3aeee2304e5e16f7c7a9 Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Change to common source file not applicable to open-vm-tools. commit d379cf84e479c11f4c3b470130a27f22005ab56d Author: John Wolfe Date: Thu Sep 8 14:51:40 2022 -0700 Change to common header file not applicable to open-vm-tools. commit 8a8bcb4ad1773fd62ad5a8bee352bf6ed34946a6 Author: John Wolfe Date: Thu Sep 8 14:51:39 2022 -0700 Move HostinfoProcessQuery() from hostinfo.c into hostinfoPosix.c. commit c6de70b61177943130040563243ba6f671a0556e Author: John Wolfe Date: Thu Sep 8 14:51:39 2022 -0700 L10n drop for open-vm-tools 12.1.0. commit b6c4eca1f575a6f116a3ce9e1bbb6e99dd134d33 Author: John Wolfe Date: Thu Sep 8 14:51:39 2022 -0700 Common header file change not applicable to open-vm-tools. commit 53f331ccbbbc57eeaf4dfc51c94ec6f3e9a31a65 Author: John Wolfe Date: Thu Sep 8 14:51:39 2022 -0700 Common header file change not applicable to open-vm-tools. commit 662eb2af666ca75532777ac28a11e29df1a6b413 Author: John Wolfe Date: Thu Sep 8 14:51:39 2022 -0700 lib/file: Speed up FileSimpleRandom.

Added code to skip terminated/stopped containers. This is done by using TaskStub to retrieve the pid for the running container. If the pid cannot be retrieved, then that container is skipped. The previously suppressed "default" namespace has been restored. Fixed another minor issue with calculating the number of containers that were added. Note: This changeset introduces a dependency on Tasks.proto, and Tasks.proto depends on a few other proto files like mount, metrics, descriptor and task. Modified the makefile to generate the necessary C++ files from the proto files. Additional notes: - .proto -> generates .pb.h, .pb.c and .grpc.pb.cc files. - For compiling and building the library (.so file), the .grpc.pb.{h,cc} and .pb.{h,cc} files are needed. - The protoc compiler generates .pb.h and .pb.c files when the --cpp_out option is specified. - The protoc compiler generates .grpc.pb.* when the --grpc_out option is specified. commit 5e79bc1414f31a07a9fb74c624b8b435546e0212 Author: John Wolfe Date: Mon Feb 7 09:40:00 2022 -0800 Common source file change not applicable to open-vm-tools. commit 75f3a3e2e6b4cfec157c02e8f06e5ac139ad98cc Author: John Wolfe Date: Mon Feb 7 09:40:00 2022 -0800 Common header file change not applicable to open-vm-tools. commit 192667e6e65ad7d7592798ef567278dbe15c293d Author: John Wolfe Date: Thu Jan 20 15:01:49 2022 -0800 Last minute 2022 copyright updates to several files. commit 99c00042476803def0d1aea4fc28cd59e271859d Author: John Wolfe Date: Thu Jan 20 11:50:29 2022 -0800 Update ChangeLog with the granular push of Jan. 20, 2022. - plus ChangeLog update of Jan 2, 2022. commit bd0f9506e5ad3ee42c95cbd1aea0c9381e4abf59 Author: John Wolfe Date: Thu Jan 20 11:40:15 2022 -0800 Common header file change not applicable to open-vm-tools. commit ddd97d710b1b49a2d8b3679ac07c70feacb2aeb0 Author: John Wolfe Date: Thu Jan 20 11:40:15 2022 -0800 Common header file change not applicable to open-vm-tools. commit b4a4387294cc9dc3cb890093398abad4d0800bc2 Author: John Wolfe Date: Thu Jan 20 11:40:15 2022 -0800 Common header file change.

While both Fuse 2 and Fuse 3 runtime can be installed on a Linux system, vendors would prefer to switch from Fuse 2 to Fuse 3 at the same time for all products to be available with the base OS. Updating the configure.ac file to check for the presence of the Fuse 3 or Fuse 2 development packages in the build environment. Providing configure options to allow users to control the version of Fuse to be used. --without-fuse - vmblock-fuse and vmhgfs-fuse will be disabled. --with-fuse=fuse3|3 - use Fuse 3.x --with-fuse=fuse|2 - use Fuse 2.x --with-fuse=auto - check for Fuse 3 or Fuse 2 availability; disable vmblock-fuse and vmhgfs-fuse if unavailable. --with-fuse - implicit "yes". --with-fuse=yes - check for Fuse 3 or Fuse 2 availability; disable vmblock-fuse and vmhgfs-fuse if unavailable. Pull request: https://github.com/vmware/open-vm-tools/pull/544 Fixes issue: https://github.com/vmware/open-vm-tools/issues/314 The vmblock-fuse code is also used by WorkStation. Configure defines are not available in internal builds. Reworked preprocessor tests to use FUSE_MAJOR_VERSION from the fuse headers to determine API to be used during compilation. commit d0571b23fe1513c0ec83e8b57bd8e91edd5b86a3 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Changes to common source files not applicable to open-vm-tools. commit 7776c845db0bc24c5103d80a8d8f76d73f79ec39 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Change to a common header file not applicable to open-vm-tools. commit ec4040bfc25818e5979f8c681f13b4c0e3d9c38a Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Changes to a common source file not applicable to open-vm-tools. commit 3695f042018aedbca6d37751d3d1577bf1887aa1 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Common source file change not applicable to open-vm-tools. commit 7cb1006b6f362a1e19b6dbaea5ae30bd727d4f5b Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Fix potential integer overflow when calling g_timeout_source_new() or g_timeout_source_new_seconds(). commit c69332a9252413b265b4a146c072bcae8b16a3d3 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Common header file change not applicable to open-vm-tools. commit 1c916a09107b2b6c901488587711db569ade9223 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Changes to common header files not applicable to open-vm-tools. commit 8296854e348014441368af01edc41c728b80de86 Author: John Wolfe Date: Tue Dec 21 12:48:50 2021 -0800 Clean up of guest OS tables.

Issues have been reported on some newer versions of Linux where the VM failed to reboot at the end of a traditional customization. The command '/sbin/telinit 6' exited abnormally due to SIGTERM sent by systemd and where telinit is a symlink to systemctl. This fix checks if telinit is a soft link to systemctl and if yes, retries a system reboot until the telinit command succeeds or the reboot literally happens. commit f8eedf7070b0c11c73f86e1374c004a1bc0212e1 Author: John Wolfe Date: Mon Jun 7 08:25:08 2021 -0700 Change to common source file not directly applicable to open-vm-tools. commit 5acc2a69256aa351e38d7abe1914b7785de6d6b2 Author: John Wolfe Date: Mon Jun 7 08:25:08 2021 -0700 Changes to common source files not applicable to open-vm-tools. commit 9ff3c61c5d5ab58922c55db77704bab56bac75d6 Author: John Wolfe Date: Mon Jun 7 08:25:08 2021 -0700 Common source file change not applicable to open-vm-tools. commit dc39fc8c67180b3e7213d01449868482c17b36f4 Author: John Wolfe Date: Mon Jun 7 08:25:08 2021 -0700 Switch the current thread to "C" locale to parse /proc files. commit 912fecf2f9e28a8083fee6e29b83a926c35b8661 Author: John Wolfe Date: Fri May 21 11:57:16 2021 -0700 Match the copyright style as in the main source repository. commit b35069156e3d73b2149e78238eed38671481b0b4 Author: John Wolfe Date: Thu May 20 11:58:01 2021 -0700 Update ChangeLog with the granular push of May 20, 2021 - plus ChangeLog update of May 3. commit dde0b8e906ea1ef1f5e752e51e9887be002b07f0 Author: John Wolfe Date: Thu May 20 11:38:38 2021 -0700 Common header file change not applicable to open-vm-tools. commit b4a3a288b013202bfc01f99093c420b75051ffb4 Author: John Wolfe Date: Thu May 20 11:38:38 2021 -0700 Change to common source file not immediately applicable to open-vm-tools. commit b2c8baeaa8ac365e1445f941cf1b80999ed89a9d Author: John Wolfe Date: Thu May 20 11:38:38 2021 -0700 Remove unwanted "volatile" from static variable used with g_once_init_enter() The glib api documentation for g_once_init_enter() specifically states that "volatile" should NOT be used with the address passed as the argument. Recent compilers (GCC-11 & clang 11) and recent versions of glib-2 will result in a warning that the "volatile" qualifier has been dropped if it has been used. Remove the unneeded and unwanted "volatile" qualifier from the definition of "inited" in pollGtk.c.

Introduce peek() to the asyncsocket API, only supported by TCP vtable. Peeks are similar to recv(), except that they do not drain the socket after reading. Subsequent peek/recv reads the same data back. However since recv does SSL_Read, a recv() following a peek() may not get the same data as peek() after SSL is initialized. This is not a problem when peeks are done before SSL setup. Implementation notes: - peek is a one-shot operation. The poll callback is unregistered once it fires (recv keeps the callback until recv is cancelled). - non-partial peek is not supported, so the peek callback will be fired when any amount of data less than or equal amount of the requested length is available in the socket buffer. - It is possible to invoke recv() or peek() recursively from within the peek() callback. A peek is disallowed from within the recv() callback. commit 95cbd990ec667a34b6b76c1d53182317c33e5330 Author: John Wolfe Date: Thu May 20 11:38:38 2021 -0700 Fix an ASSERT in bora/lib/misc/timeutil.c. Fix a problem with TimeUtil_NtTimeToUnixTime on Arm that was encountered when running tools tests on Apple silicon. The problem was the routine assumed that a variable was 32-bits if VM_X86_64 was not defined. This may have been true in the past, but it is no longer true now that the code is also built for 64-bit Arm. commit abfd599dea18f0f6a5acc35d539cec0322d194df Author: John Wolfe Date: Thu May 20 11:38:38 2021 -0700 Additional changes for the network interface limit logging. 1) Use the VM_SAFE_STR macro for string null check. 2) Since free() is NULL safe, remove the "if" check before the free(). 3) Fix an alignment issue. commit 78f19996702a14066d9f5424c522167780151f0e Author: John Wolfe Date: Thu May 20 11:38:37 2021 -0700 Update terms used in code that is distributed publicly in open-vm-tools.

VGauth is a single action service. With the GUESTRPCPKT_FIELD_FAST_CLOSE flag added, VMX closes the vsocket as soon as the RPC response is sent. This cleans up the vsocket connections faster and minimizes the number of connect() failures in the guest. commit 092a4cfd7b577b55abc71e636748dbbb25240171 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit 8994d7c3a9c5164c5c88b5d882d32238a9964628 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Asyncsocket: Add comments about AsyncSocket_SetErrorFn usage. Document that AsyncSocket_SetErrorFn must be called before an internal asyncsocket callback can fire and trigger a call to the error handler. The error handler must be set immediately after the asyncsocket is created, either from the poll thread, which requires no additional synchronization, or while holding the asyncsocket lock, which is passed via pollParams. commit 4abc2d2b6cf754914e6c0f08d245a2852f04e368 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit a3db034717c4bd77ffcf4f6ac2682096d360e2e0 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Tools gdp plugin updates. commit 037825f8b73cdc04e6f19e5868224e3e911c1acb Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit 62daa89681b48ad0fe33a92332a04a5c33c862e2 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit 306366fa79a390b632c89b4eab29fdd01659b688 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Format the VMCI port in a guest RPC connect request using "unsigned int" type. commit 6c01c0ad957152d00cec28fb059a5781acb5a607 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit e0b4963730505f1bb746b1f93998b5e9a8a9af58 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not directly applicable to open-vm-tools. commit 2693e19a54d93dac0a206bf2634f6e6b908fc8b9 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 vmwgfxctrl: Refactor the 'for' loop index declarations for C89 compatibility. commit 86fa9e400b3866407be4acfebd52f9093483f8b1 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Common header file change not applicable to open-vm-tools. commit d9dae1062ab61a15c54f02ccc8b74f69a1ead3f9 Author: John Wolfe Date: Mon May 3 19:39:40 2021 -0700 Fusion does not need to fork on certain file opens anymore.

This has impacted several OSS packages. Consumers of newer versions of glib2.0 must not include glib headers in an extern "C" block. GTK 3.20 has deprecated gdk_display_get_device_manager(); using the newer gdk_display_get_default_seat() when the GTK version is >= 3.20. The return value from read() must be used to avoid an unused result warning from the compiler. This can be avoided by using dummy retyping in the case where the return value is not used or in this case, using the returned value in a debug log message.

Unfortunately there are two problems with this approach: 1) Distros now ship without xorg, so the xorg .so doesn't exist and there's nothing to check. 2) Distros (e.g. Fedora) do heavy optimizations and remove the .modinfo section from the .so, so the string cannot be found even though the driver exists. To fix both, stop depending on being able to parse the elf binary of the xorg driver. Instead, let the plugin check for the existence of the drm driver with a sufficiently high version, and if it exists, use kms. This removes the dependency on X for kms. Also increase the version of vmwgfx required to ensure atomic mode-setting plus relevant bug fixes (in the kernel since 2017) are available. commit c5b510fded54592eae1c5a4a61f8119f69666a3f Author: John Wolfe Date: Thu Feb 4 09:57:03 2021 -0800 Add a switch to the vm-support script to transfer the support bundle to the hypervisor The vm-support script unconditionally transferred the support bundle to to the VMware hypervisor, thereby filling vmware.log.

Added an option '-x' to both scripts to let the user elect to transfer the guest support bundle to the host. commit f7ddf98958097197468cd153227317cba205a19c Author: John Wolfe Date: Thu Feb 4 09:57:03 2021 -0800 Add NVMe capability for vmbackup.

On some Guest OSes, the repeatedly executing /sbin/telinit command can fail while a reboot is happening and the init daemon has been killed. This change sets log level to info, not error, for failed /sbin/telinit command. Note: The first /sbin/telinit commmand failure will fail customization with error 127; this is unchanged. commit ecf07f0bf6cbab57c9e970efa32ca53e6c207aab Author: John Wolfe Date: Fri Jan 22 12:25:41 2021 -0800 lib/file/file.c: Use Err_Errno instead of errno directly. commit 741870477774566d0c065ae7f432ecda3e0caafc Author: John Wolfe Date: Fri Jan 22 12:25:41 2021 -0800 lib/file/file.c: Fix memory leak Don't continue; jump to ensure string free. commit 5f8671ff14899d34f7abc07550812d5951e927b0 Author: John Wolfe Date: Fri Jan 22 12:25:41 2021 -0800 Invalid file name causes the VMX to crash in log file rotation Parse the log file names without using sscanf.

Since POSIX platforms (i.e. ESXi, MacOS, Linux) support nanosecond resolution for semaphore wait times, a new timed semaphore wait routine with nanosecond resolution is introduced. commit a2396202001370cf37d4cea3087b6a83bcb0cb61 Author: John Wolfe Date: Tue Dec 22 12:22:03 2020 -0800 Common header file change not applicable to open-vm-tools. commit bc9196b59469f9269c73d8cca605e7628d6b3d17 Author: John Wolfe Date: Tue Dec 22 12:22:03 2020 -0800 Update copyright date for products to be released in 2021. commit 6284afd17986fe3053fc6d69560d319dacb5299c Author: John Wolfe Date: Tue Dec 22 12:22:03 2020 -0800 Common header file change not applicable to open-vm-tools. commit dec004f0853468937b8e1e7b25f5062c58d131e2 Author: John Wolfe Date: Tue Dec 22 12:22:03 2020 -0800 Common header file change not applicable to open-vm-tools. commit 30874008335209a51531a50bc27d05b7fac513fe Author: John Wolfe Date: Tue Dec 22 12:22:03 2020 -0800 Common header file change not applicable to open-vm-tools. commit 816f569db5207ffe321372edf75836eb4cff1992 Author: John Wolfe Date: Thu Dec 10 19:34:56 2020 -0800 Common header file change not applicable to open-vm-tools. commit 197124856f619fb303f8bb5f91489c8f6753e0e4 Author: John Wolfe Date: Thu Dec 10 19:34:56 2020 -0800 Change to common source file not immediately applicable to open-vm-tools.

Starting with glibc 2.32, the Linux libc-dev no longer provides the /usr/include/rpc/rpc.h header. The configure script will detect the availability of the libtirpc package and use the rpc.h header from /usr/include/tirpc/rpc/rpc.h. This fix extends the necessary compilation and linking options to the build of the open-vm-tools services test programs that utilize RPC.

In times long past, EINVAL was chosen for the errno returned when a Unicode problem was detected. This overloads EINVAL, particularly when using POSIX system calls. Unfortunately, the overloading makes it very difficult to recover from some errors as there is no way to know the difference between a "real" EINVAL and a Unicode problem EINVAL. Over 10 years of data shows that we *RARELY* encounter Unicode errors. Inspecting the source base shows the code segments that do check for errno after an error either: 1) Post the errno value and die. 2) Have switch handle cases but also have a default catcher. 3) Have an if/else waterfall with a final else. Another observation is that Unicode routines are not involved with anything that would return a math related errno (e.g. ERANGE, EDOM). Changing the value of UNICODE_CONVERSION_ERRNO to ERANGE and avoid any overloading. commit d35ef560247e7f0bd798ae45646eeaee38d3a12b Author: John Wolfe Date: Mon Nov 9 12:29:03 2020 -0800 Changes to common source files not applicable to open-vm-tools. commit e47338fd721f3393823d778e487ee3c937594311 Author: John Wolfe Date: Mon Nov 9 12:29:02 2020 -0800 Common header file change not applicable to open-vm-tools. commit d6ba5ae8996e44e52c9ee967c6d44036fa2eba92 Author: John Wolfe Date: Mon Oct 26 17:29:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit a4c1458c67a291c2a2d69d2a7f829daac00face1 Author: John Wolfe Date: Mon Oct 26 17:29:55 2020 -0700 Common header file change not directly applicable to open-vm-tools. commit 727a554c3d44ae615e23361a450ccfd793198019 Author: John Wolfe Date: Mon Oct 26 17:29:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit e18e67f727d0354b08a55b685178fd05f542c6da Author: John Wolfe Date: Mon Oct 26 17:29:54 2020 -0700 Fix memory leaks.

Currently, the vmsvc service periodically downloads the Global Configuration from the GuestStore and applies the downloaded configuration. 'vmusr' service doesn't have the support. In this changeset, made the changes for both vmusr and vmsvc services to periodically check and apply the changes. To keep thing simple and easy, the new approach is check the modification time every time the regular tools conf is read and if changes are detected, the configuration is applied. With this new approach, signalling mechanism is not needed and that code is removed. vmsvc: * Starts a background thread which periodically fetches the global configuration from the GuestStore. vmusr: * No background thread is created. But checks and loads the configuration everytime the regular tools.conf is checked. commit 00531302d7e56bddaa037e5e4ae006135a34cca8 Author: John Wolfe Date: Mon Oct 26 17:29:53 2020 -0700 Check in tools gdp plugin OVT installer code. commit d3ed2aebcb5b33581ad49f85e41e6fa0eca98738 Author: John Wolfe Date: Fri Oct 16 21:03:23 2020 -0700 Get the latest README.md from the stable-11.1.x branch commit eae2394df5fc0856c4bc4133c569e13f5e327efb Author: John Wolfe Date: Tue Oct 6 14:30:56 2020 -0700 Common header file change not applicable to open-vm-tools. commit b76c75ae9a48e68e55412d0fd97f238a66409ea0 Author: John Wolfe Date: Tue Oct 6 14:30:56 2020 -0700 Changes to common source files not directly applicable to open-vm-tools. commit b966cb3822b3a8cb9815af6f2da46f8f367b58cd Author: John Wolfe Date: Tue Oct 6 14:30:56 2020 -0700 Changes to common source files not directly applicable to open-vm-tools. commit 99d5a9ea8605ad5ce085f109d4e3d378bf327db4 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit fd75f811c8d09b662ee78f072d90ec6c915fcec6 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit c1f88125233b074398bb6ba38d7b5c2ae19e7085 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit ece245c662d28b3880eb0ee40e8c427a2aafe4c8 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Changes to common source files not directly applicable to open-vm-tools. commit 695d2fab5c8a036b8b7584877fb490bf505c178b Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit 84d87f789f8d93e5d265afe4288a6111c90341c4 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit 48e96c64a3a51b9bca2dd7614b1c7a04cc4dbb1d Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit 49103fbe71707b99323c996a23ec22fde5cb1438 Author: John Wolfe Date: Tue Oct 6 14:30:55 2020 -0700 Common header file change not applicable to open-vm-tools. commit 08333afefd17ac7617ba5d4b1e3f087cccd97056 Author: John Wolfe Date: Tue Oct 6 14:30:54 2020 -0700 L10n drop for open-vm-tools 10.2.0. commit 6cbee265af33370fe41a47db63c90cfd52ecdba4 Author: John Wolfe Date: Tue Oct 6 14:30:54 2020 -0700 Common header file change not applicable to open-vm-tools. commit a869ed128c313d6335316fa10ebfbe15ace2be73 Author: John Wolfe Date: Tue Oct 6 14:30:54 2020 -0700 Common header file change not applicable to open-vm-tools. commit b6f81f00fcfbc602838b48feca9f85da2847cf59 Author: John Wolfe Date: Tue Oct 6 14:30:54 2020 -0700 Common header file change not applicable to open-vm-tools. commit 66eb1b16e7cea8399c67d71eee45acd015e12a49 Author: John Wolfe Date: Tue Oct 6 14:30:54 2020 -0700 Adding the vgauthImport utility to open-vm-tools.

Caching the file attributes in HGFS on the server-side can reduce the time significantly (from experimental results, 35s => 8s). It was also discovered that Posix_RealPath is called repeatedly to check whether a path is a symlink, since HgfsServerGetLocalNameInfo is called when handling a series of requests. Integrate a key-value cache to HGFS server to cache the symlink check results and file attributes, using the file path as the key. This task will be divided into multiple change: 1. Add oplock support 2. Add a customized LRU cache in HGFS server for file attributes and symlink check results - New files: hgfsCache.h/c: implements a customized LRU cache which is built by combining two data structures: a doubly linked list and a hash table. - The cache will be allocated only when oplock is enabled. - The cache relies on the file change monitor provided by oplock to ensure there is no stale data. When adding an entry into the cache, also register the file change callback to oplock. Upon receiving the file change callback, invalidate the cache. Once the cache is full, remove the LRU entry and unregister the file change callback for it. commit e860f4aaaac89aa0043a948ae79ac1b2a8dab6b4 Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Change to common header files not applicable to open-vm-tools. commit fac536ee236d87e779a323bc99e6f5c66550abf8 Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Common header file change not directly applicable to open-vm-tools. commit f7ac1c4b756bc8a0b4b248299f725df773858695 Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Common header file change not applicable to open-vm-tools. commit 07b065dbceadc6968f9b145dcef13a9fdfde1587 Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Define "Unknown Command" Macro to replace hard coded strings in rpc files This changeset finds all instances of the hardcoded string "Unknown Command" in a few rpc files and replaces it with a macro defined in a shared header file. commit 468fcf407bd71983cca6652d71547099772f37f6 Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Changes to common header files not directly applicable to open-vm-tools. commit bab170d03516705690ec347ba4c0ffbf5338f42a Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Changes to common header files not applicable to open-vm-tools. commit 2f11b89440dfb80a8b3a8ff1b343642367b2491b Author: John Wolfe Date: Tue Aug 18 07:14:11 2020 -0700 Fix log recursion issue in DestroyRpcChannel() Avoid calling g_xxx() logging routines in any function directly or indirectly invoked from VmxGuestLog().

To make the cache correct, we will use the oplock(Windows)/lease(Linux) to monitor the file/directory change event. When the file/directory changes, the item in cache will be invalidated. In this change, two new functions are defined: - HgfsOplockMonitorFileChange This function is used to monitor the change event for a file/directory, and the callback will be called if file/directory is changed. - HgfsOplockUnmonitorFileChange This function is used to cancel the change event monitoring. This patch only implements the oplock support for Windows host, the support for Linux will be delivered in another patch. commit 3b40aceb52c8fd2b001c0b5aa192018fad3fa2c1 Author: John Wolfe Date: Fri Aug 7 12:03:24 2020 -0700 Common header file change not applicable to open-vm-tools. commit 6757870e37708413ea005c5790f292f1115b12ec Author: John Wolfe Date: Fri Jul 31 13:36:35 2020 -0700 The new table driven guest identification code did not handle Red Hat properly.

But EOF can't be reached immediately. The reason is pre-customization script is launched by perl script, and killing perl script process doesn't kill the pre-customization script process. This code update includes: 1. Do not read stdout/stderr when gosc command process exits abnormally to avoid the EOF blocking. 2. Add READSTATUS_PENDING_TO_EOF in enum ReadStatus to avoid the confusion with READSTATUS_PENDING. 3. Close the write ends of pipes (stdout[1]/stderr[1]) for child command process before it exists. 4. In processPosix.c, the write ends of pipes have been closed in line 180, 181, so the read ends should be closed in line 254, 255. 5. Add explicit note for the beginning and the end of the perl script log. commit 641874bfb831fc63e8ea289ee00d12d67734285e Author: John Wolfe Date: Fri Jul 31 13:36:34 2020 -0700 Common hesder file change not applicable to open-vm-tools. commit 534f6bcbdda25bc9999c306cdd0d8e3e89f8f95c Author: John Wolfe Date: Fri Jul 31 13:36:34 2020 -0700 Common header file change not applicable to open-vm-tools. commit f1625fd8cad09739da8e67c952c27bdd425e096b Author: John Wolfe Date: Fri Jul 31 13:36:33 2020 -0700 Common header file change not applicable to open-vm-tools. commit 44ad3675a33b804dd262bfab3279410aff442bcc Author: John Wolfe Date: Tue Jul 21 11:53:01 2020 -0700 Fix memory leak issue for "vmtoolsd" binary on receiving SIGINT or SIGUSR1.

Coverity reports a "dereference after NULL check" in BkdoorChannelStart. However, at the point of dereference it's known that chan->inStarted is TRUE, which means chan->in is guaranteed to be non-NULL, so it's not a bug. Still, given that an input channel, if present, must have been started before calling BkdoorChannelStart, it's possible to do some code cleanup that will also get Coverity to stop reporting the issue. Change what's currently a test into an ASSERT, test chan->in rather than chan->inStarted, and add comments to make it clearer what's going on. commit 5e1388e10828cec3885ab0107711f483fe732d33 Author: Oliver Kurth Date: Thu Jun 11 20:43:21 2020 -0700 Common header file change not applicable to open-vm-toold. commit e52ffacc9d189e4a4fd5880e3b1c9593cb6c32b6 Author: Oliver Kurth Date: Thu Jun 11 20:43:21 2020 -0700 Fix Coverity-reported dead code issue.

Make it clear that the "short name" of a Linux distro has a default value and that the default value should not be overwritten unless VMware does this. If someone cheats and sends down an unsupported "short name", the guestMapper will protect the software stack, mapping the unsupported "short name" to that of the guestOS config found in the VMX file. We know that is OK since the VM couldn't power on and run the guest unless it was valid. All older, supported ESXi have updates that contain the guestMapper. If the guestMapper is not in place - an older, unpatched release - the software stack can become confused causing problems and crashes.

It's time to deprecate the corresponding VMGuestLib_GetHostMemKernOvhdMB API in GuestSDK. The documentation will be update denoting that this API is deprecated. After one or two releases, the API will be removed completely. Untill then, the API is modified to explicity return 0 for the metric. * Only a few functions listed in vmGuestLib.h are exposed in the vmGuestLibJava interface. The remaining functions are encapsulated in '#ifndef SWIG' to hide them from SWIG utility which is used to generate the Java bindings. Note: The external customer facing documentation for this API will be documented later. Note: Once this changeset is submitted, the vmStatsProvider module will be updated to stop using the deprecated API. commit 6a5123f2e020e6e35d2111777f99879c791088a2 Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Common header file change not applicable to open-vm-tools. commit a1bb9128e3087602ce5280f43d639cd87e5487cc Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Changes to common source files not applicable to open-vm-tools. commit 0682a7064f553a3d50a55ac881b0e5e6b78a257e Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Update to bora/public/vm_tools_version.h Add tools versions 11.1.1 and 11.1.5 to bora/public/vm_tools_version.h commit d1ce2c08c47a82a4cfddae55a55c4b9619b08042 Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Common header file change not applicable to open-vm-tools. commit 53473f83f7dfda6a0b592bbfdf1a5e6144b426e7 Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Changes to common source files not applicable to open-vm-tools. commit a99fcf43fbef64cc36473750a441cb2f6265a1dd Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Backout previous changes to common source files. commit 8f68d75e3d6642e2f8d7d7ef9a4cbfcab052b3be Author: Oliver Kurth Date: Tue May 26 15:32:58 2020 -0700 Changes to common source files not applicable to open-vm-tools. commit 34d7c760709cec8938488d1c60831960bc30441d Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Common source file changes not directly applicable to open-vm-tools. commit f3423aa7a1d2f0d864eaaa6d11b8b34eacb04c3c Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Common source file changes not directly applicable to open-vm-tools. commit e25e233b02557a944babad5d8140472eb25c2210 Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Common header file change not applicable to open-vm-tools. commit 5ed3bc8fe0cfee2b15b469b4f5e71c1fbb28bad9 Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Backout previous common header file change - not applicable to open-vm-tools. commit 2f6676c69e332677b7bd598505de02d6e78e1fbb Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Common header file change not applicable to open-vm-tools. commit 0128592fd7ec406824237af5e184f72726715f59 Author: Oliver Kurth Date: Tue May 26 15:32:57 2020 -0700 Updating the bora/public/vm_tools_version.h history.

This has been already done for tar tools build/target. The same is being done for OVT builds. * Used various static libraries for building guestlib in OVT instead of depending on vmtoolslib. Similar thing has already been done for appmonitor library in OVT. * GuestSDK_{Panic|Debug|Warning|Log} functions in vmtoolslib are not used anywhere and hence they are completely removed from the code. commit 66b70db09241bef18694bc0e45bd94a1804b201d Author: Oliver Kurth Date: Tue May 26 15:32:56 2020 -0700 Common header file change not directly applicable to open-vm-tools. commit e4fdad51c47f5e2605a3ad9dd9e3451b25ba6fbd Author: Oliver Kurth Date: Tue May 26 15:32:56 2020 -0700 Changes to common header files not applicable to open-vm-tools. commit a760361f0b603f0dabe2e82cec1a728e5b3f796b Author: Oliver Kurth Date: Tue May 26 15:32:56 2020 -0700 Pre-enablment: Recognition of FreeBSD 13 commit 80ce8edc04fcd3253174be476b0f09bdf5527bf5 Author: Oliver Kurth Date: Tue May 26 15:32:56 2020 -0700 Improve logging on signature verification If xmlsec and vgauth are built inconsistently, xmlSecSize can differ between the two, which results in a key datastructure being a different size, and vgauth ends up looking in the wrong place in memory for the signature check status.

Valgrind complained about a minor leak within FileLock_Lock when running test-vmx Firmware.Efi.QuickBoot . FileLockScanner builds a list of "active locks" and traverses that list repeatedly, but whenever it decides to remove an entry from the list, it would simply leak it. This change ensures that the list item is not leaked by Posix_Free()ing it once it is no longer needed. commit c27281f24e043f64a9e627e2eaeccd9c196fc938 Author: Oliver Kurth Date: Tue May 26 15:32:56 2020 -0700 Hgfs Linux/OSX Server: fix write-only shares access check creating new files Linux and OS X Hgfs server has an incorrect failure status check when a user has a write-only share enabled. In a write-only share any failure is mapped to EACESS unless the error is ENOENT when a new file is to be created.

The poll loop for the appInfo is being tweaked (destroyed and recreated) for every conf reload even when nothing related to appinfo changed.

In few workflows like instant clone, when a large number of VMs are cloned at the same time, if the appinfo plugin runs at the same time in all the VMs, the underlying ESXi may encounter heavy load. To avoid these situations, a random poll interval should be used for the appinfo whenever applicable workflows are detected. Detecting a 'rpc channel reset' is a simple approach to detect. In this changeset, add the following changes: - Added a new callback function for the 'rpc channel reset'. If the rpc channel is reset, a new random poll interval is calculated and poll timer is adjusted accordingly. If the existing appinfo poll interval is greater than the minimum interval of 30 seconds, random interval will be generated between 30 and appinfopollinterval. If the existing poll interval is less than the minimum 30 seconds time, then random interval will not be changed. - Code refactoring for few functions. - Changed one global variable as static. - Added few debug/info log messages. commit 9b79ed9bc118860518028828a6c7858af62757a8 Author: Oliver Kurth Date: Tue Apr 21 14:43:46 2020 -0700 Common header file change not applicable to open-vm-tools. commit 9a9aab94168189302e74dd97939415ef1e07fb20 Author: Oliver Kurth Date: Tue Apr 21 14:43:46 2020 -0700 Common header file change not applicable to open-vm-tools. commit a8086de2c4317d4463b0bb1a3b602cda0833bd3e Author: Oliver Kurth Date: Tue Apr 21 14:43:46 2020 -0700 Common header file change not applicable to open-vm-tools. commit 8e2e15a2da54f3603a7ccdc09249aec0b58f6ed9 Author: Oliver Kurth Date: Tue Apr 21 14:43:46 2020 -0700 Free old ununsed loggers when tools.conf changes.

When RpcOut falls to Backdoor, it stays with Backdoor permanently for the life of vmtoolsd service. It is a long standing bug in the reset handling code. Typically, channel type is not changed during reset. Our reset handling code can either keep the channel type same or switch it from vsocket to Backdoor, but it can't do other way. Though it is supposed to switch to vsocket on reset caused by events like vmtoolsd being restarted or VMX breaking the channel for some VM management operation. With this change when we start the channel, we always try vsocket first unless Backdoor is enforced by the caller. Using Backdoor for too long is not desirable because privileged RPCs can't be used on such channel. So, we need to retry switching the channel back to vsocket periodically. We don't want to try vsocket on every RpcChannel_Send call because that adds to overhead and increases the latency of RpcChannel_Send due to connection timeouts. So, we retry vsocket with a backoff delay between 2sec-5min. As some RpcChannel callers intend to use Backdoor channel we need to differentiate between such usage from the callers that create vsocket channel and fallback to Backdoor. Therefore, introduced a concept of mutable channel. The vsocket channel is mutable as it can fallback to Backdoor and restore vsocket. However, if a caller creates Backdoor channel, it will not be mutable and stay with Backdoor for its lifetime. As vmxLogger frequently connects and disconnects the channel for every log message and does not use any privileged RPC, so make it use Backdoor channel permanently to avoid frequent vsocket connections. Additionally, removed the redundant 'stopRpcOut' interface and renamed 'onStartErr' to 'destroy'. commit 4a049ceec7e2e1fafbfece34e29c4f7b14962e7c Author: Oliver Kurth Date: Tue Apr 21 14:43:45 2020 -0700 AppInfo updates.

However, untrustedCerts is NULL only if no untrusted certs are found, in which case the code that dereferences untrustedCerts isn't executed. commit 3777c7008da506fe35b1b8003b3d1ae7067662ae Author: Oliver Kurth Date: Wed Apr 1 11:31:36 2020 -0700 lib/mics/sha1.c: Include string.h unconditionally. string.h is part of POSIX, lets include it unconditionally commit 8774b6383b6dcb024335dd115c8fcae2b00c4d16 Author: Oliver Kurth Date: Wed Apr 1 11:31:36 2020 -0700 Common header file change not applicable to open-vm-tools. commit 0bbaf772c27a8df913ade55d7086d651652a2f17 Author: Oliver Kurth Date: Wed Apr 1 11:31:36 2020 -0700 vmtools: fix compiler errors in posix service discovery core plugin As we build the vmtools for arm (unfortunately not on main), we hit a compiler warnings "ISO C90 forbids mixed declarations and code" in this new code. commit 65b6819ed3ba196f52639c5984be40475ce2fffc Author: Oliver Kurth Date: Wed Apr 1 11:31:36 2020 -0700 Common header file change not applicable to open-vm-tools. commit 5ef6682ae1038942f4b1d873cd0ca93d688f83e0 Author: Oliver Kurth Date: Wed Apr 1 11:31:35 2020 -0700 Common header file change not applicable to open-vm-tools. commit 74351e2121e866ca0b28644a6fc545c97e8bfbda Author: Oliver Kurth Date: Wed Apr 1 11:31:35 2020 -0700 Fix localization issue of vmware-vgauth-cmd 1. default msg catalog folder is wrong, add correct msgCatalog in vgauth.conf 2. rename vmsg file name to "VGAuthCli" since file name used in main is "VGAuthCli" 3.

The rpcChannel library is now used to do RPC abstraction. * modules/*/vmmemctl/*: refactor of the vmmemctl module as part of adding support for Mac OS guests. * modules/linux/pvscsi/pvscsi.c: don't clobber RESERVATION_CONFLICT sdstat up from linux pvscsi driver. * modules/linux/shared/*: VMCI changes unrelated to the guest driver. * modules/linux/vmhgfs/fsutil.c, modules/linux/vmhgfs/inode.c: fix the case where two directories refer to the same inode. * scripts/linux/*: support older versions of NetworkManager. 2009-08-24 Marcelo Vanzin * Resync with internal trunk (2009.08.19) * configure.ac: remove support for Linux kernels < 2.6.9. * lib/include/vmtools.h, libvmtools/vmtoolsLog.c, doc/api/services/util.txt: add new log handled that allows appending to existing log files, and fix an issue where old log files would be "rotated" whenever the config file was reloaded. * lib/appUtil/appUtilX11.c, lib/ghIntegration/ghIntegrationX11.c, lib/include/appUtil.h: fix compilation issues on FreeBSD when unity was enabled. * lib/dnd/dndLinux.c, lib/include/vmblock_user.h, tests/testVmblock/*: add vmblock tests and, as part of the change, do some refactoring of vmblock related functions. * lib/guestInfo/guestInfo.c, lib/include/wiper.h, lib/wiper/*, toolbox/toolboxcmd-shrink.c, toolbox/toolboxShrink.c: refactor the wiper structures so that they behave the same on Win32 and other platforms, and also reuse data structures already in use by other parts of the code. This fixes an "use after free" issue that toolbox-cmd had on Win32. * lib/guestInfo/guestInfo.c, lib/guestInfo/guestInfoInt.h, lib/guestInfo/guestInfoPosix.c, lib/guestRpc/nicinfo.x, lib/include/guestInfo.h, lib/include/netutil.h, lib/include/slashProc.h, lib/netutil/netUtilLinux.c, lib/slashProc/*, services/plugins/guestInfo/guestInfoServer.c: add support for sending more network-related information to the host, such as routing tables and name servers. * lib/hgfsBd/hgfsBd.c: don't log RPC errors when HGFS is disabled. * lib/hgfsHelper/*, lib/include/hgfsHelper.h, lib/vixTools/vixTools.c: new library with functions to query information about HGFS; expose some HGFS properties through VIX. * lib/hgfsServer/*, lib/hgfsServerPolicyGuest/hgfsServerPolicyGuest.c, lib/include/hgfsServerPolicy.h: fix checking of whether an object belongs to a particular share; this was causing issues with invalid information being returned in certain cases. * lib/hgfsServer/*, lib/include/hgfsProto.h: changes to support new VIX API calls (mostly affecting Win32 only). * lib/include/guestCaps.h, lib/include/unityCommon.h: add boilerplate for new RPCs for setting windows as sticky / non-sticky (not yet implemented). * lib/include/hgfsProto.h: new definitions for the next version of the HGFS protocol. * lib/include/xdrutil.h: make XDRUTIL_ARRAYAPPEND() more type-safe when using GCC. * lib/misc/codesetOld.c: fix some issues with UTF16 -> UTF8 conversion. * lib/rpcChannel/rpcChannel.c, libvmtools/signalSource.c, libvmtools/vmtools.c, libvmtools/vmtoolsConfig.c: g_assert -> ASSERT. * lib/unityWindowTracker/unityWindowTracker.c: fix issue with z-ordering of modal dialogs. * libvmtools/vmtoolsConfig.c: fix some old config translation issues. * modules/freebsd/shared/*, modules/freebsd/vmblock/*: make vmblock work on FreeBSD 8. * modules/freebsd/vmmemctl/*, modules/linux/vmmemctl/*, modules/solaris/vmmemctl/*, : refactoring and code changes to support the driver on Mac OS X. * modules/linux/vmblock/*, modules/linux/vmci/*, modules/linux/vsock/linux/*: remove compatibility code for older kernels. * modules/linux/vmhgfs/*: fix memory leak in HgfsAccessInt(). * modules/linux/vmxnet3/*: fix kunmap usage in vmxnet3_shm, and reset the shared pages when the char device is closed. * modules/linux/vsock/linux/af_vsock.{c,h}, modules/linux/vsock/linux/util.c: add vsock protocol negotiation for notifyOn ops. This allows the driver to negotiate with the remove end which version of the notification protocol to use. * modules/linux/vsock/linux/notify.c, modules/linux/vsock/linux/notify.h, modules/linux/vsock/linux/notifyQState.c, modules/linux/vsock/linux/vsockPacket.h: add pktOn protocol. This new protocol improves performance by detecting changes in the queue state instead of sending WAITING_READ and WAITING_WRITE packets. * services/plugins/hgfsServer/hgfsPlugin.c, services/plugins/resolutionSet/resolutionSet.c, services/vmtoolsd/mainLoop.c, services/vmtoolsd/pluginMgr.c, services/vmtoolsd/toolsRpc.c: load plugins even when an RPC channel cannot be instantiated (i.e., when running outside of a virtual machine); this allows plugins to perform actions (at load time) also when running outside virtual machines (e.g., to undo some configuration done when the OS was run in a VM). * services/vmtoolsd/mainLoop.c, services/vmtoolsd/mainPosix.c, services/vmtoolsd/toolsCoreInt.h: handle SIGHUP differently; instead of stopping the service, just re-load the config data. This should make it easier to integrate the tools service with other tools such as logrotate. * toolbox/toolbox-cmd.c, toolbox/toolboxcmd-stat.c: remove memory info query, which didn't really return useful information. * vmware-user/copyPasteUI.cpp: if the clipboard/primary with most recent timestamp has no data on it, try the other before giving up during copy/paste. 2009-07-22 Marcelo Vanzin * Resync with internal trunk (2009.07.17) * configure.ac: fix detection of "dot" and its usage in the doxygen config file. * configure.ac, libguestlib/Makefile.am, libguestlib/vmguestlib.pc.in: install vmguestlib headers and add new pkgconfig script. * lib/dndGuest/dnd.{cc,hh}, lib/include/dndBase.h, vmware-user/dndUI.{cpp,h}: fix an issue where the DnD code would prevent drops to other windows in Unity mode, instead of just intercepting drops to the desktop. * lib/dndGuest/dnd.{cc,hh}, lib/dndGuest/dndRpc.hh, lib/dndGuest/dndRpcV3.cc, lib/include/dndBase.h, vmware-user/dndUI.{cpp,h}: fix an issue where the host Unity code would cause an undesired drop event. * lib/dndGuest/dnd.{cc,hh}, lib/dndGuest/dndRpc.hh, lib/dndGuest/dndRpcV3.cc, lib/include/dndBase.h: cleanup mouse simulation code, and fix an issue where a drag would be canceled if the contents were dragged out of a guest and then back in. * lib/dndGuest/dndRpcV3.cc, vmware-user/copyPasteDnDWrapper.cpp, vmware-user/dndUI.cpp, vmware-user/dndUI.h, vmware-user/dragDetWnd.cpp, vmware-user/dragDetWnd.h: several DnD fixes; make the DnD code behave more like other GTK applications (based on analysing the flow of signals on a test widget), and get rid of one of the detection windows, merging both the Unity and non-Unity windows. Also, some code refactoring. * lib/ghIntegration/*, lib/guestRpc/*, lib/include/guestCaps.h, lib/include/unityCommon.h: add stubs for a few new GHI functions (setting window focus, tray icon updates and enhanced app info) - currently only implemented on Win32. * lib/ghIntegration/ghIntegrationX11.c: examine WM_CLASS when determining which DE Tools are running in. The previous code was failing to show a few entries set as "OnlyShowIn=xxx" because checking WM_NAME wasn't enough to properly detect the desktop environment in certain cases. * lib/guestApp/guestAppPosixX11.c: use gconftool-2 to detect the user's browser, since gnome-open fails to open "file://" URLs which contain query strings. Also, use "kde-open" when running under KDE. * lib/guestInfo/guestInfo.c, lib/include/wiper.h, lib/wiper/wiperPosix.c: allow shrinking LVM partitions. * lib/include/appUtil.h: partial refactoring of icon retrieval code. * lib/include/dbllnklst.h, lib/misc/dbllnklst.c: inline linked list functions. * lib/include/guest_os.h, lib/misc/hostinfoPosix.c: add a couple of distros to the known distro list. * lib/include/netutil.h, lib/netUtil/netUtilLinux.c: add Linux interface name, index lookup routines. * lib/include/system.h, lib/system/systemLinux.c, services/plugins/timeSync/timeSync.c: fixes a few bugs in the backwards time sync code, mostly due to unit mismatches. * lib/include/unityWindowTracker.h, lib/unity/unity.c, lib/unity/unityPlatform.h, lib/unity/unityPlatformX11Window.c, lib/unityWindowTracker/unityWindowTracker.c: expose two new properties in the window tracker to save an RPC to retrieve those properties. * lib/include/vmtoolsApp.h, services/vmtoolsd/mainLoop.c, services/vmtoolsd/pluginMgr.c, services/vmtoolsd/toolsCoreInt.h: add support for "application providers", which allow plugins to add support to new kinds of application frameworks through vmtoolsd. * lib/unity/unityPlatformX11.c: only enable GIO channels when Unity is actually active. * lib/unity/*: cleanup old GTK1 code. * libvmtools/vmtoolsConfig.c: don't complain if config file is empty. * modules/linux/dkms.conf, modules/linux/dkms.sh: fix dkms.conf, and provide a script to create a dkms tree from open-vm-tools. * modules/linux/shared/vmci_queue_pair.h, modules/linux/vmci/vmciKernelIf.c: remove two (now) unneeded functions. * modules/linux/vmhgfs/*: code cleanups, properly initialize the list head, and allow receives to timeout so that hibernation works. * modules/linux/vmxnet/vmxnet.c, modules/linux/vmxnet3/vmxnet3_drv.c: fix drivers for kernels 2.6.29+. * modules/linux/vmxnet3/*: add shared memory support for faster communication between user space and the device backend; this doesn't affect the regular driver functionality, but is used by some VMware code not part of Tools. * modules/linux/vsock/*: fix an issue where it was possible for users to send VMCI datagrams directly to the hypervisor. * scripts/common/vmware-user.desktop: work around a bug in KDE where desktop files with "NoDisplay" fail to autostart. * scripts/freebsd/suspend-vm-default: use netif to bring down interfaces, since dhclient doesn't understand "-r" in the default install. * services/plugins/vmbackup/*: add some new code used by enhancements being done in the Win32 version of the plugin. * services/vmtoolsd/mainPosix.c: fix running in background when executing vmtoolsd while relying on PATH. * services/vmtoolsd/Makefile.am: point to the correct plugin install directory. * toolbox/*: better command line handling in the CLI utility, plus some code cleanup. * vmware-user/copyPaste.c, vmware-user/copyPasteDnDWrapper.cpp, vmware-user/copyPasteDnDWrapper.h, vmware-user/dnd.c: properly unregister RPCs to avoid multiple registrations (and the ensuing ASSERT) in certain cases. * vmware-user/copyPasteUI.{cpp,h}: change way data is retrieved from the clipboard, using the gtk+ clipboard wait APIs (which turn out to be more reliable than the previous approach). 2009-06-18 Marcelo Vanzin * Resync with internal trunk (2009.06.15) * docs/api/Makefile.am: replace all variables in the doxygen conf file with the correct values. * lib/appUtil/appUtilX11.c: try alternate file extensions during icon search. Sometimes a package lists its icon as icon-foo.png, but the package didn't include icon-foo.png. Instead, it included icon-foo.xpm. Ex: Ubuntu 8.04's hwtest. * lib/guestApp/guestAppPosixX11.c: change detection of the default browser so that the new help system works; the help files are not yet available in open-vm-tools. * lib/hgfs/*, lib/include/cpName.h, lib/include/cpNameLite.h, lib/include/hgfsUtil.h: avoid compiling certain parts of the source in kernel modules. * lib/hgfsServer/*: return correct error when files / directories don't exist. * lib/include/hgfsChannel.h, modules/linux/vmhgfs/*: added support for vsock channel for HGFS. * lib/include/util.h, lib/misc/utilMem.c: un-inline a bunch of functions to reduce the size of binaries. * lib/include/vm_tools_version.h: bumped Tools version. * lib/resolution/resolutionX11.c: fix for issue where the host would send a "topology set" command with a top-left corner that was not (0, 0) and cause the screen to be reconfigured in the wrong way. * lib/unity/unityPlatformX11Window.c: check for errors in calls to XQueryTree. * lib/wiper/wiperPosix.c: check return of fgets() to avoid compiler warnings. * libvmtools/vmtools.c: fix initialization of wiper library on Win32. * modules/Makefile.am: install vsock header file on Linux. * modules/freebsd/vmhgfs/*, modules/linux/vmci/*, modules/linux/vsock/*: changes related to 64-bit Mac drivers, don't affect either the FreeBSD or Linux drivers. * modules/linux/vmhgfs/hgfs.h: removed duplicate file. * modules/linux/vmhgfs/fsutil.c, modules/linux/vmhgfs/inode.c, modules/linux/vmhgfs/module.h: fix issue where two files would get the same inode number in some situations. * modules/linux/vmxnet/vmxnet.c: re-probe vmxnet2 device features on resume from hibernate, to cover the case where a VM is resumed on a platform with a different version of the device backend (bug #2209565). * scripts/resume-vm-default, scripts/suspend-vm-default: use NetworkManager to handle networking where it is available. * services/plugins/hgfsServer/Makefile.am, services/plugins/vix/Makefile.am: fix installation of vmusr plugins that are shared with vmsvc. * services/plugins/timeSync/timeSync.c: fix backwards time sync. * services/vmtoolsd/cmdLine.c, toolbox/toolbox-cmd.c: print build number as part of "-v" output. * toolbox/toolboxcmd-shrink.c: correctly ignore unsupported partitions when shrinking. * toolbox/toolbox-gtk.c: changes for the new help system, not yet available for open-vm-tools. * toolbox/toolboxInt.{c,h}, toolbox/toolboxScripts.c: some code refactoring. * vmware-user/Makefile.am: fix linking when compiling without gtkmm. 2009-05-22 Marcelo Vanzin * Resync with internal trunk (2009.05.18) * configure.ac, m4/vmtools.m4: check for PAM and enable PAM support when available. * configure.ac, services/plugins/*/Makefile.am, tests/*/Makefile.am: avoid the "-rpath" hack to create plugins, using plugin_LTLIBRARIES instead (and manually fixing things when necessary). Thanks to Dominique Leuenberger for the suggestion (and sample patch). * docs/api/Makefile.am: fix doc target directories. * configure.ac, lib/Makefile.am, lib/deployPkg/*, lib/include/deployPkg.h: remove the deployPkg code, which depends on some VMware code that is not yet open source. * lib/backdoor/*, lib/hgfs/*, lib/hgfsBd/*, lib/include/*, lib/include/compat/*, lib/message/*, lib/misc/dbllnklst.c, lib/rpcOut/rpcout.c: as part of sharing code between user-level code and kernel modules, some files have been tagged with more than one license. * lib/dndGuest/*, lib/include/dndBase.h, lib/include/dndMsg.h, lib/include/unity*, lib/unity/unityPlatformX11.c: implement mouse movement from within the guest; this avoids a dependency on "unofficial" mouse APIs in the VMware host code, making DnD more reliable, and makes a few things (such as cancelling an ongoing DnD operation) easier. * lib/file/filePosix.c: make File_FullPath()'s behavior consistent when the input path starts with a '/'. * lib/ghIntegration/ghIntegration.c: send more info about the "start menu" contents to the host (only usable for Windows guests). * lib/ghIntegration/ghIntegrationX11.c: prettify the category names of menu items. This is a temporary solution before actually reading this information from .desktop files. * lib/guestApp/guestApp.c, libguestlib/vmGuestLib.c, lib/include/guestApp.h, toolbox/toolbox-gtk.c, vmware-user/foreignVM*, vmware-user/vmware-user.cpp, configure.ac, lib/Makefile.am, lib/include/socketMgr.h, lib/socketMgr.*: remove code related to "foreign VM" support, which was never really used. * lib/guestInfo/guestInfo.c, lib/include/wiper.h, lib/wiper/wiperPosix.c: properly report disk info for LVM volumes. * lib/hgfsServer/hgfsDirNotify*, lib/hgfsServer/hgfsServer.c: add support for directory / file monitoring. It's currently only implemented on Mac OS X. * lib/hgfsServer/hgfsServer*: fix issue where it was possible to create a file on a read-only share on Windows hosts. * lib/hgfsServer/hgfsServer*, lib/hgfsServerManagerGuest/*, lib/include/hgfs*.h, services/plugins/hgfsServer/hgfsPlugin.c, services/plugins/vix/foundryToolsDaemon.c: some refactoring caused by the work to make HGFS support pluggable transports. * lib/include/procMgr.h, lib/procMgr/procMgrPosix.c: remove ProcMgr_GetAsyncStatus(). * lib/include/vmsupport.h, scripts/vm-support, xferlogs/xferlogs.c, services/plugins/guestInfo/guestInfoServer.c: new feature to automatically collect support data from the guest from the VMware UI. * lib/panicDefault/*, lib/user/*: change file names to avoid clash with another file (Mac OS linker doesn't really like that). * lib/rpcChannel/rpcChannel.c: try to reinitialize the outbound channel on failure. * lib/vixTools/vixTools.c, lib/include/vixCommands.h, lib/include/vixOpenSource.h: add backend for new VIX API call to list the guest's filesystems. * libvmtools/vmtoolsLog.c: lazily open the log file, instead of opening it during configuration of the log system. This way two processes can use the same conf file and not overwrite each other's log files (assuming the conf data is sane). * modules/Makefile.am, modules/linux/vmci/Makefile.kernel, modules/linux/vsock/Makefile.kernel: don't store VMCI module symbols in /tmp during build; this avoids a possible symlink attack that could cause data to be overwritten when building open-vm-tools. * modules/*/*, vmblock-fuse/*: remove a lot of duplicated files by either moving them to a shared location or reusing files that were already available elsewhere. * modules/freebsd/vmblock/subr.c, modules/freebsd/vmblock/vmblock_k.h, modules/freebsd/vmblock/vnoops.c: fix a possible kernel crash caused by trying to read / write to the mount point (something vmware-user does to detect whether it's using fuse or non-fuse vmblock). * modules/linux/pvscsi/*: adds support for a generic msg framework that is currently used to deliver hot-plug/unplug notifications; get rid of a few divisions; fix a bug where pvscsi_probe could return 0 (aka success) if a call to kmalloc() failed; remove a few unused fields. * modules/linux/shared/vmci*: mostly changes related to the host VMCI drivers (removed user-level queue-pair daemon, added support for trusted VMCI endpoints) to keep binary compatibility between the host and guest VMCI drivers. * modules/linux/hgfs/inode.c: check host's access rights when checking file permissions, so that permissions are correctly checked when the guest's user id is different from the host's user id. * modules/linux/bdhandler.*, modules/linux/filesystem.c; modules/linux/tcp.*, modules/linux/transport.*,: postpone opening the channels so that module can load successfully even if shared folders are disabled on the host; fix a synchronization problem between recv and close/open; allow hibernation to work by timing out the recv thread; correctly handle failures in recv, including injecting a dummy error to the pending requests when the recv thread exits; move the recv code to the channel's implementation so that it can be simpler. * modules/linux/vmxnet3/vmxnet3.c, modules/linux/shared/compat_pci.h: fix Wake-On-LAN for 2.6.27 and newer Linux guests. * modules/linux/vsock/linux/*: changes to support trusted VMCI host apps; pull out notification and stats logging code into their own files. * modules/solaris/vmhgfs/vnode.c: do not substitute errors returned by uiomove() calls with EIO, propagate returned error code (which is EFAULT) up the stack. * services/vmtoolsd/Makefile.am, scripts/common/linux/pam.d/vmtoolsd-x64, scripts/common/linux/pam.d/64/vmtoolsd: install the 64-bit PAM config file with the correct name. * services/plugins/powerOps/powerOps.c: fix running default scripts by making sure the path to the script is absolute. * services/vmtoolsd/Makefile.am, services/vmtoolsd/pluginMgr.c: use info from the configure step to define the plugin path; this avoids requiring a symlink to be placed in /etc/vmware-tools for vmtoolsd to be able to find the plugins. * services/vmtoolsd/toolsRpc.c: send the build information to the host so it's logged in the VM's logs. * toolbox/toolbox-cmd.c, toolbox/toolboxcmd-*, toolbox/toolboxCmdInt.h: make string comparison case-insensitive on Win32. * toolbox/toolboxcmd-shrink.c: properly finish the shrinking process by sending the "disk.shrink" RPC to the host. * toolbox/toolboxScripts.c: fix showing default settings for power ops scripts (should show default script enabled, not script disabled). * vmblock-fuse/Makefile.am: fix compilation on FreeBSD. * vmware-user/copyPasteUI.cpp: disallow copy-paste text of size greater than 4MB, instead of truncating the data. * vmware-user/dndUI.*, lib/dndGuest/dnd.cc, lib/include/dndBase.h: remove drag timeout callback (which was not needed), and add new signal to indicate that a GH DnD was cancelled. * vmware-user/Makefile.am: remove C++ link hack (not needed now since vmware-user has C++ code already). 2009-04-23 Marcelo Vanzin * Resync with internal trunk (2009.04.17) * configure.ac, Makefile.am, docs/*: build API docs for vmtools; the documentation files are provided under a BSD-style license. * configure.ac, Makefile.am, guestd/*, lib/Makefile.am, lib/guestInfo/*, lib/include/vmbackup_def.h, lib/include/vmBackup.h, lib/vmBackupLib/*, libvmtools/Makefile.am, services/plugins/vmbackup/vmbackup_def.h: remove guestd from open-vm-tools, and clean up code in other places that was only there because of guestd. * configure.ac, modules/solaris/vmblock/*, modules/solaris/vmmemctl/*: add Solaris vmblock and vmmemctl driver sources. The vmmemctl module also includes a user-level daemon (vmmemctld.c). * lib/conf/conf.c, lib/include/conf.h, libvmtools/vmtoolsConfig.c: remove unused config options. * lib/deployPkg/toolsDeployPkg.h: code refactoring. * lib/dnd/dndClipboard.c: if size of clipboard exceeds the maximum backdoor packet size, only keep text data (dropping the RTF data). * lib/dnd/dndLinux.c, lib/include/dnd.h, lib/include/vmblock.h, vmware-user/copyPaste.c, vmware-user/dnd.c, vmware-user/vmware-user.cpp, vmware-user/vmwareuserint.h, vmware-user-suid-wrapper/main.c: detect whether plain vmblock or vmblock-fuse is being used, allowing the same executable to be used with either. * lib/dndGuest/*, vmware-user/copyPaseDnDWrapper.{cpp,h}, vmware-user/dndUI.{cpp,h}, vmware-user/dragDetWnd.{cpp,h}: vmware-user/vmware-user.cpp: more DnD V3 protocol work. * lib/ghIntegration/*, lib/include/guestCaps.h, lib/include/unityCommon.h: work related to mapping Outlook folders over HGFS and exposing the Windows Recycle Bin to the host (doesn't really affect open-vm-tools). * lib/ghIntegration/ghIntegrationX11.c: restore the native environment when launching external applications. This doesn't really affect open-vm-tools. * lib/guestRpc/*, vmware-user/copyPasteUI.{cpp,h}: implement RTF and file contents copy & paste. * lib/include/circList.h, lib/include/vm_basic_math.h, lib/include/vm_device_version.h, modules/linux/*, modules/Makefile.am: changes to share files between the user space code and the kernel code, instead of duplicating the same source files in different places. * lib/include/rpcChannel.h, lib/rpcChannel/*, tests/testDebug/testDebug.c, test/vmrpcdbg/debugChannel.c: some code cleanup, and fix crash when dealing with multiple reset messages. * lib/include/system.h, lib/system/systemLinux.c, services/vmtoolsd/mainPosix.c: remove System_Daemon() (replaced with Hostinfo_Daemonize()). * lib/include/unityCommon.h, lib/unity/*: ressurrect UNITY_RPC_WINDOW_SHOW and UNITY_RPC_WINDOW_HIDE RPCs. * lib/procMgr/procMgrPosix.c: fix ProcMgr_IsProcessRunning(). * lib/system/systemLinux.c: fix shutdown / reboot commands on Solaris; fix rebuilding of native environment from variables set by VMware scripts (this last one doesn't really affect open-vm-tools). * lib/unicode/unicodeSimpleTypes.c: speed up UnicodeIANALookup, and fix case where C++ constructors could call UnicodeIANALookup before Unicode_Init() was called by lazily creating the internal cache. * libguestlib/*: link libguestlib against libvmtools. This avoids having two definitions of certain symbols (like Debug()) when an application links to both libraries. * modules/linux/vmblock/linux/control.c: only set directory entry owner when needed. * modules/linux/vmhgfs/bdhandler.{c,h}, modules/linux/vmhgfs/dir.c, modules/linux/vmhgfs/file.c, modules/linux/vmhgfs/filesystem.c, modules/linux/vmhgfs/fsutil.c, modules/linux/vmhgfs/inode.c, modules/linux/vmhgfs/module.{c,h}, modules/linux/vmhgfs/page.c, modules/linux/vmhgfs/request.{c,h}, modules/linux/vmhgfs/super.c, modules/linux/vmhgfs/tcp.{c,h}, modules/linux/vmhgfs/transport.{c,h}: cleanup use of atomic variables in HGFS; add a transport abstraction layer, and add an initial version of a socket-based transport (not yet stable and not yet supported by any released VMware product). * modules/linux/vmxnet3/vmxnet3.c: fix build on kernel 2.6.29. * modules/linux/vsock/af_vsock.c: export more functions to other kernel modules; some changes to statistics gathering code. * modules/solaris/vmhgfs/filesystem.c: make module loadable on Solaris 9. * modules/solaris/vmhgfs/vnode.c: unify mapping of HGFS to Solaris error codes. * scripts/*: restart network before running user scripts in resume scripts. * services/plugin/powerOps/powerOps.c: fix running default power scripts. * services/vmtoolsd/pluginMgr.c: better error logging. * toolbox/toolbox-cmd.c: fix help string. * vmblock-fuse/block.c: fix vmblock-fuse compilation on FreeBSD. 2009-03-18 Marcelo Vanzin * Resync with internal trunk (2009.03.13) * configure.ac: check for FreeBSD kernel tree when building modules; warn about which version of make to use when building kernel modules on FreeBSD and Solaris; add compiler defines for identifying Solaris 9 and 11. * configure.ac, modules/Makefile.am: handle SYSDIR on FreeBSD. * guestd/main.c, modules/solaris/vmhgfs/Makefile: remove HGFS-related that is now obsolete with the recent changes to the HGFS module on Solaris. * guestd/toolsDaemon.c: default to the configuration dir when the power script path is not absolute. * guestd/toolsDaemon.c, lib/include/guestInfo.h, lib/netUtil/netUtilLinux.c: handle case when all network interfaces have been disabled and send an "unknown" IP address to the host. * guestd/toolsDaemon.c, services/vmtoolsd/toolsRpc.c: always send TOOLS_VERSION_UNMANAGED from an open-vm-tools build, so there's no need for a config file option anymore. * hgfsclient/*: make it link to libvmtools to avoid code duplication. * lib/appUtil/appUtil.c: update list of "skippable" apps when figuring out an application's path. * lib/auth/authPosix.c, scripts/linux/pam.d/*, guestd/Makefile.am, services/vmtoolsd/Makefile.am : change the name of the PAM application to "vmtoolsd" to reflect the new service name. * lib/dnd/dndFileContentsUtil.h, lib/dnd/dndInt.h, lib/dndGuest/*.hh, and corresponding files in lib/include: relocate private headers. * lib/ghIntegration/ghIntegration.c, lib/ghIntegration/ghIntegrationInt.h, lib/ghIntegration/ghIntegrationX11.c, lib/include/unityCommon.h: glue code for Outlook mirrored folder, which does not affect open-vm-tools. * lib/guestRpc/guestlibV3.x, lib/include/vmGuestLib.h, libguestlib/vmGuestLib.c: add new guestlib counters. * lib/include/conf.h, toolbox/toolbox-gtk.c: remove the need for the "helpdir" config option; this doesn't really affect open-vm-tools since the help files are not yet included. * lib/include/guest_os.h, lib/misc/hostinfoPosix.c: more guest OS names; fix name used to identify Solaris to match what VMware's host code expects. * lib/include/guestStats.h: documentation changes. * lib/include/hostinfo.h, lib/user/hostinfoPosix.c: add a new function that behaves like daemon(3), but is more Mac OS-friendly. * lib/include/toolsLogger.h, lib/Makefile.am, lib/toolsLogger/*: removed library, which is not used anymore. * lib/include/vm_basic_types.h, lib/misc/timeutil.c: fixes to compile under (Open) Solaris 11. * lib/include/vmtoolsApp.h, services/plugins/vmbackup/stateMachine.c, services/vmtoolsd/mainLoop.c, services/vmtoolsd/mainPosix.c, services/vmtoolsd/serviceObj.c, services/vmtoolsd/toolsCoreInt.h: add new signal handler to gather debugging information from a running vmtoolsd instance. * lib/misc/posixPosix.c: fix off-by-one error. * lib/unity/unity.c, lib/unity/unityPlatform.h, lib/unity/unityPlatformX11.c, lib/unity/unityPlatformX11Settings.c: always send Unity updates using RPCI; this avoids a possible race between replying to an incoming RPC and sending an Unity update from a different thread; also, API documentation updates. * lib/unity/unityPlatformX11.c: verify the DnD detection window was initialized before actually using it. * lib/unity/unityPlatformX11Settings.c, lib/unity/unityPlatformX11Window.c: reset _NET_WM_DESKTOP as necessary before exiting Unity; this could cause guest taskbars to disappear when in Unity mode. * lib/unity/unityPlatformX11.c, lib/unity/unityPlatformX11Window.c, lib/unity/unityX11.h: examine WM_CLIENT_LEADER when gathering application information; certain applications use this property to define the window where the WM_COMMAND property should be. * lib/vixTools/vixTools.c: do not follow symlinks when deleting files in the guest using the VIX API. * libvmtools/vmtools.c, libvmtools/vmtoolsLog.c: allow the logging subsystem to be re-configured, and clean up the logging data when unloading the library; allow ${USER} and ${PID} to be used in log file paths. * modules/freebsd/vmblock/subr.c, modules/freebsd/vmblock/vnops.c: fix kernel panic on FreeBSD 7. * modules/linux/*/Makefile: remove GCC version check. * modules/linux/*/compat_wait.h: fix COMPAT_DEFINE_WAIT for "vanilla" 2.4 kernels. * modules/linux/vmhgfs/Makefile.normal: fix build of HGFS module on 2.4 kernels. * modules/linux/vmxnet/*, modules/linux/vmxnet3/*: avoid using compat functions when they're not needed; add compatibility functions for newer Linux kernels. * modules/linux/vsock/linux/af_vsock.c: fix two races; one when the socket state changed between calls to VSockVmciRecvStreamCB and VSockVmciRecvPktWork, and another when trying to read from the socket after a RST arrived after the socket got a detach notification. * modules/solaris/vmxnet3/*: add Solaris vmxnet3 driver. * rpctool/*: add "rpctool", a simple, stand-alone tool to send RPC commands to the host software. * services/plugins/guestInfo/guestInfoServer.c: don't cache configuration data. * services/plugins/guestInfo/perfMonLinux.c: fix problem with overwriting flags after GuestInfoMonitorReadMeminfo() was called. (Same as fix to lib/guestInfo on previous release.) * services/plugins/powerOps/powerOps.c: handle power ops-related options sent from the host. * services/vmtoolsd/mainLoop.c: handle re-loading the configuration file. * services/vmtoolsd/mainPosix.c: exec after forking on Mac OS, since CoreFoundation classes don't work after a fork. * services/vmtoolsd/pluginMgr.c: allow both 32 and 64 bit plugins to be installed on Solaris by loading them from the appropriate directory; add library loading code that is not really needed (nor used) in open-vm-tools. * services/vmtoolsd/toolsRpc.c: send another "capability" the host expects from Tools. * toolbox/toolbox-gtk.c: add F1 shortcut to invoke help. * toolbox/toolboxScripts.c: fix issue with freeing data that should not be freed. * vmware-user/*: implement the new DnD protocol (V3). 2009-02-18 Marcelo Vanzin * Resync with internal trunk (2009.02.13) * configure.ac, m4/vmtools.m4: clean up a lot of the library detection code. * configure.ac: remove support for gtk+ 1.2 (code already depended on it in any case); enforce need for glib 2.6.0 or later due to new code being added; add detection for gtkmm; check for C++ compiler when it's needed; reorder the include path to avoid clashing with system headers in some situations. * guestd/foundryToolsDaemon.*, vmware-user/foundryToolsDaemon.*, guestd/Makefile.am, vmware-user/Makefile.am: moved shared source files to a new place to avoid duplication. * hgfsmounter/hgfsmounter.c: add support for Solaris. * lib/appUtil/appUtilX11.c: fix loading of icons when the name has a period. * lib/dnd/dndClipboard.c, lib/dnd/dndInt.h, lib/dnd/dndMsg.c, lib/dnd/Makefile.am, lib/dndGuest/*, lib/include/copyPasteBase.h, lib/include/copyPaste.hh, lib/include/copyPasteRpc.hh, lib/include/copyPasteRpcV3.hh, lib/include/dndBase.h, lib/include/dndClipboard.h, lib/include/dndFileContentsUtil.h, lib/include/dndFileList.hh, lib/include/dnd.h, lib/include/dnd.hh, lib/include/dndInt.h, lib/include/dndMsg.h, lib/include/dndRpc.hh, lib/include/dndRpcV3.hh, lib/include/dndTransportGuestRpc.hh, lib/include/dndTransport.hh, lib/include/libExport.hh, vmware-user/copyPaste.cpp, vmware-user/copyPasteUI.{cpp,h}, vmware-user/copyPasteV3.h, vmware-user/copyPasteWrapper.{cpp,h}, vmware-user/dnd.cpp, vmware-user/Makefile.am, vmware-user/vmware-user.{c,cpp}, vmware-user/vmwareuserInt.h, vmware-user/stringxx/string.{cc,hh}, vmware-user/stringxx/ubstr_t.hh: add support for new version of the DnD protocol. * lib/guestInfo/guestInfoPerfMonLinux.c: fix problem with overwriting flags after GuestInfoMonitorReadMeminfo() was called. * lib/guestRpc/guestlibV3.x, lib/include/vmGuestLib.h, libguestlib/vmGuestLib.c: add new host stats. * lib/guestRpc/Makefile.am: fix a few compatibility issues with non-GNU versions of make. * lib/hgfsServer/hgfsServer.c, lib/hgfsServer/hgfsServerInt.h, lib/hgfsServer/hgfsServerLinux.c, */hgfsProto.h, modules/freebsd/vmhgfs/vnops.c, modules/freebsd/vmhgfs/vnopscommon.{c,h}: don't trust the local VFS layer, check the HGFS server to see if an operation would succeed. * lib/include/rpcChannel.h, lib/rpcChannel/*: add new Guest RPC channel abstraction library used by the new "core services" code. * lib/include/vmrpcdbg.h, tests/*: add test code from the "core services" project. * lib/include/vmtoolsApp.h, lib/include/vmtoolsd_version.h, services/vmtoolsd/*: add "vmtoolsd", the new service "shell" used in the "core services" project. * lib/unity/unityPlatformX11Window.c: don't send initial "region" updates for shaped windows. This works around an issue where resizing a shaped window would not work as expected in Unity mode. * lib/wiper/wiperPosix.c: fix major number detection for disks on newer Linux kernels. * libvmtools/Makefile.am: link more libraries needed by vmtoolsd and the new plugins. * modules/linux/pvscsi/pvscsi.c, modules/linux/pvscsi/pvscsi_version.h: use PCI-specific memory allocation functions and update driver version. * modules/linux/vmci/vmciKernelIf.c: disable queue pair support in the host version of the driver on older Linux kernels. This doesn't affect the guest driver. * modules/linux/vmci/vmci_queue_pair.h: implement MSG_PEEK support on Linux driver. * modules/linux/vmhgfs/bdhandler.c, modules/linux/vmhgfs/compat_sched.h, modules/linux/vmmemctl/os.c: fix issue with HGFS module interfering with suspend / hibernation on newer Linux kernels (bug #2523263). * modules/linux/vmhgfs/compat_cred.h, modules/linux/vmhgfs/file.c, modules/linux/vmhgfs/filesystem.c, modules/linux/vmhgfs/inode.c: changes for compatibility with newer Linux kernels, where it's not possible to change fsuid/capabilities directly anymore. * modules/linux/vmhgfs/compat_pagemap.h, modules/linux/vmhgfs/page.c: fix warning, and compatibility changes for newer Linux kernels (2.6.28.1 and newer; bug #2530616). * modules/linux/vmhgfs/inode.c: fix creation of symlinks (bug #2531303). * modules/linux/vmxnet/vmxnet.c: use PCI-specific memory allocation functions. * modules/linux/vmxnet/vmxnet.c, modules/linux/vmxnet3/vmxnet3.c: add option to disable LRO. * modules/linux/vsock/af_inet.{c,h}, modules/linux/vsock/util.{c,h}: add MSG_PEEK support; remove ifdefs that were disabling support for queue pairs on the host kernel module; fix compilation with certain versions of gcc (bug #2531283). * modules/solaris/vmhgfs/*: move backdoor handling code to the HGFS driver; this makes the user-level code to handle the driver (currently in vmware-guestd) obsolete. * modules/solaris/vmxnet/*: add vmxnet driver for Solaris, under the CDDL. * services/plugins/*: add all currently available "core services" plugins. The current set of plugins provide the functionality available in vmware-guestd; there are a few plugins that replace functionality from vmware-user, but not all features are ported yet (and vmtoolsd - with vmware-user plugins - and vmware-user cannot run at the same time). * toolbox/toolboxAbout.c: fix the copyright character. * toolbox/toolbox-cmd.c: reword a few messages, fix typos. * toolbox/toolboxCmdInt.h, toolbox/toolboxcmd-record.c, toolbox/toolbox-gtk.c, toolbox/toolboxRecord.c: remove the "record" functionality from tools (due to internal request). * toolbox/toolboxInt.c, toolbox/toolboxScripts.c, toolbox/toolbox-scripts.c: changes to use the new config file format used by the "core services" code. * */Makefile.am: make sure 'rm' and 'mv' are being used instead of $(RM) and $(MV) (which are not defined by automake; bug #2492040). 2009-01-21 Marcelo Vanzin * Resync with internal trunk (2009.01.19) * configure.ac: detect the presence of FUSE libraries. * configure.ac, Makefile.am: compile kernel modules for Solaris, and vmblock-fuse module if FUSE is available. * lib/ghIntegration/ghIntegrationX11.c: retrieved localized application names. * lib/guestInfo/guestInfo.c, lib/guestInfo/guestInfoPosix.c, lib/include/hostinfo.h, lib/misc/hostinfo_misc.c, lib/misc/hostinfoPosic.c, lib/vixTools/vixTools.c: refactoring to move code shared with other VMware products to a common library. * lib/guestRpc/guestlibV3.x, lib/guestRpc/Makefile.am, lib/include/vmGuestLib.h, libguestlib/*: add new iteration of the "guestlib" protocol. This is a more extensible solution than the current protocol, and should make it easier to add new information when needed. * lib/include/dynarray.h, lib/include/dynbuf.h, lib/misc/dynarray.c, lib/misc/dynbuf.c: make some DynArray/DynBuf functions inline for speed. * lib/include/unityCommon.h: more documentation about the Unity protocol. * lib/unity/unityPlatformX11.c: fix Unity<->guest desktop ID mappings. * libvmtools/vmtoolsLog.c: change the way log domains are configured; now sub-domains inherit the default handler for the app if no handler is specified. * modules/freebsd/vmhgfs/state.c, modules/freebsd/vmhgfs/state.h, modules/freebsd/vmhgfs/vnopscommon.{c,h}: implement support for mmap on the Mac OS driver, which allows running executables from an HGFS share. The FreeBSD module still does not support this functionality. * modules/freebsd/vmhgfs/transport.{c,h}: refactoring for sharing structure definitions. * modules/linux/pvscsi/pvscsi.c, modules/linux/vmblock/linux/module.c, modules/linux/vmci/vmci_drv.c, modules/linux/hgfs/module.c, modules/linux/vmmemctl/os.c, modules/linux/vmsync/sync.c, modules/linux/vmxnet/vmxnet.c, modules/linux/vmxnet3/vmxnet3.c: add support for Novell's proprietary module info tag ("supported"). * modules/linux/vmci/vmciKernelIf.c: add support for VMCI queue pairs on the host. This does not affect the driver when it runs inside virtual machines. * modules/linux/vmci/*.h, modules/linux/vsock/*.h: some changes in the common code to support Mac OS X, and also queue pairs on the Solaris VMCI module. * modules/linux/vsock/af_vsock.{c,h}: add functions for registering with the vsock driver from within the kernel. * modules/linux/*/Makefile: add $(LINUXINCLUDE) to the compiler flags; this allows compiling the modules against recent kernels which removed that from $(KBUILD_CPPFLAGS). * modules/Makefile.am: add support for compiling Solaris kernel modules. * modules/solaris/vmhgfs/*: initial release of the Solaris HGFS driver in open-vm-tools. Driver is licensed under the CDDL 1.0. * vmblock-fuse/*: add the user-level implementation of the vmblock driver, which is build on top of FUSE, to open-vm-tools. vmware-user hasn't yet been modified to use this version of vmblock. * vmware-user/copyPaseV3.h: new header introduced during development of the next version of copy paste / DnD for X11 platforms. 2008-11-23 Marcelo Vanzin * Resync with internal trunk (2008.12.19) * configure.ac, */Makefile.am: standardize on using libtool archives for the libraries. This also means several makefiles were removed, since there's no need to build two archives of the same library anymore. * configure.ac: add logic to detect glib 2.6; this is the minimum version required by the "Core Services" project. Currently it's an optional dependency. * configure.ac: disable Unity when user specifies --disable-multimon. * configure.ac: actually build the pvscsi modules if the detected kernel version supports it. * configure.ac, Makefile.am, lib/guestInfo/Makefile.am, lib/stubs/Makefile.am, libvmtools/*, lib/include/vmtools.h: add the "vmtools" shared library used in the "Core Services" project. The library is a collection of a lot of other libraries used by most VMware Tools programs, and adds some functionality on top of glib that is used in the "Core Services" project.

The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. ========= GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15.

The default log level is not chatty, so few messages should make it to syslog during normal operation. * The GUI version of the toolbox was removed. open-vm-tools 2011.03.28 changes: * HGFS mounter and vmusr's suid wrapper were changed to avoid issues with symlink attacks. A new mount utility for vmblock on Solaris and FreeBSD was added. * The VMCI driver was thoroughly reworked so that it can serve as both the host and guest VMCI driver. This is mostly targeted at supporting nested VMs. * vmusr got better integration with X's session manager, including proper cleanup during session teardown. * Unity has been enhanced to better handle some desktop environments. * Many small bug fixes in other areas, including updates for newer Linux kernels. open-vm-tools 2011.02.23 changes: * Some copy & paste issues with KDE were fixed. * Mostly cleanups and bug fixes, with a few build enhancements. open-vm-tools 2011.01.24 changes: * Mostly cleanups and bug fixes. * Install code fixed to handle translation catalogs correctly. open-vm-tools 2010.12.19 changes: * New version of DnD code lands in open-vm-tools. The host part of the new DnD protocol is not available yet in VMware products, though. * vmtoolsd gets some new functionality to support new features being developed internally. * vmxnet driver for FreeBSD fixed to allow changing the MAC address. * lots of bug fixes and other cleanups in various areas. open-vm-tools 2010.11.17 changes: * Mostly cleanups and bug fixes. * vmxnet3 on Solaris now supports jumbo frames. open-vm-tools 2010.10.18 changes: * The unity plugin has received some refactoring work, and the menu gathering code has been enhanced to be more DE-agnostic and support the new app icon code. It now needs glib 2.24 to compile. * Several bug fixes and enhancements to the VIX plugin. * Bug fixes to the guest info plugin so that it better supports VMs with several network interfaces. * Other minor enhancements and bug fixes in several areas, including vsock, vmmemctl and copy & paste. open-vm-tools 2010.09.19 changes: * Mostly cleanups and minor bug fixes. * VIX plugin has been updated with lots of new commands being added to the next VIX API release. open-vm-tools 2010.08.24 changes: * HGFS and VMCI kernel module bug fixes, and updates to compile in newer Linux kernels. * HGFS server interface refactoring was finished, now supports the transport abstraction available for the kernel interface. * VIX operations are now properly implemented on Solaris, plus new operations added to support features under development. * Other minor cleanups and bug fixes. open-vm-tools 2010.07.25 changes: * Features previously provided by vmware-user are now provided as vmtoolsd plugins. vmware-user has been removed and code that interacted with it changed to start the correct vmtoolsd instance. * Lots of cleanup: removed old compatibility headers not needed anymore, removed dead code, consolidated logging code. * Time synchronization now works more like NTP. * New code for features not yet exposed by VMware host software is being added. open-vm-tools 2010.06.16 changes: * VMCI moves towards unifying the guest and host driver APIs, and gets support for MSI/MSI-X. * More work on new VMCI-backed HGFS protocol. * vmmemctl: Linux driver removed (it's now upstream), plus cleanup and simplification of the FreeBSD and Solaris drivers. * some Linux kernel compatibility fixes. * Cleanup of old kernel support code. * Some cleanup of old VIX features. * toolbox-cmd was updated to use newer APIs, and got some i18n enhancements. * some bug fixes and enhancements to the logging code. * update detection and use of some needed libraries. * More progress in making libraries thread-safe. open-vm-tools 2010.04.25 changes: * VMCI and HGFS get some initial work for new features. * vmbackup support has been extended to more systems, allowing its use even if the system lacks a proper "sync" implementation. * A few bug fixes in different areas: Unity/X11, vmware-user startup on upstart-based systems, and other minor fixes / thread safety fixes. * The pvscsi driver was removed from the open-vm-tools distribution (it is upstream as of Linux 2.6.33). * The vmmemctl driver will be upstream as of Linux 2.6.34, at which point it will be removed from open-vm-tools. open-vm-tools 2010.03.20 changes: * New i18n support for Tools; it is based on VMware's internal tools (instead of gettext). * Logging infrastructure has been enhanced and now supports rotation (without the need for logrotate) and syslog. * Bug fixes in several areas (DnD, backup support, thread safety). * Updates in Linux kernel modules for compatibility with newer kernels. * New functionality in the Unity support code. open-vm-tools 2010.02.23 changes: * Mostly bug fixes, cleanups and code refactoring. open-vm-tools 2010.01.19 changes: * Linux modules have been updated to compile on newer kernels. * Solaris modules now should compile on OpenSolaris (tested on 2009.06). * Other than those, mostly bug fixes and minor refactoring. open-vm-tools 2009.12.16 changes: * Some improvements to vmtoolsd, base libraries and and the plugin interface. * Some library refactoring: use new lock library, changes to support compilation of some code on ARM. * some fixes in configure.ac to try to correctly support newer distros. * vsock/vmci improvements. * bug fixes in the vmxnet / vmxnet3 drivers, and FreeBSD's vmblock driver. * vmxnet3 for Linux is now upstream (as of Linux 2.6.32), and will be removed from later releases of open-vm-tools. * pvscsi will be available upstream starting with Linux 2.6.33 and at that time will be removed from open-vm-tools. open-vm-tools 2009.11.16 changes: * Lots of refactoring and cleanup in the code, mainly targeting the definition of a set of public APIs. * vmblock-fuse can now replace the vmblock kernel module for DnD operations. * Fix some memory leaks in the guestInfo module. Users of the 2009.10.15 release are recommended to upgrade, or at least crossport cid 6a8d4279. open-vm-tools 2009.10.15 changes: * The HGFS module got some performance enhancements. * Minor enhancements to vmtoolsd and the logging system. * Fix for a few issues reported on the sourceforge bug tracker. * Lots of code refactoring, and a few bug fixes. open-vm-tools 2009.09.18 changes: * Mostly bug fixes and minor enhancements. * The pvscsi code was re-factored in preparation for upstreaming. The driver has been sent to the LKML for inclusion in the main Linux tree, and might be removed from open-vm-tools once it's accepted. open-vm-tools 2009.08.24 changes: * Remove support for Linux kernels < 2.6.9. * The vsock now implements a new notification protocol that has better performance than the previous. * New infrastructure for sending more network config-related information about the virtual machine to the host. * Other bug fixes and minor improvements to the code. open-vm-tools 2009.07.22 changes: * Better support for dkms by means of a script to help create a dkms tree. * "make install" now also installs header files for public libraries, plus a few fixes to incorrect install behavior. * Lots of improvements to the new DnD code. * This will be the last release with support for Linux kernels < 2.6.9. open-vm-tools 2009.06.18 changes: * Mostly a bug fix release. * vmhgfs now is able to use vsock as a transport (although backend support for HGFS over vsock is not yet released in VMware products). open-vm-tools 2009.05.22 changes: * Mostly a cleanup and bug fix release. * Fix a build issue where a symlink attack could cause the open-vm-tools build to overwrite data (by placing a symlink in /tmp). * Second (and last?) batch of changes to clean up duplicate files in the source tree, including Solaris and FreeBSD kernel modules and other module-specific shared files. * Plugins now are properly built using plugins_LTLIBRARIES so that "-rpath" doesn't need to be used (this would cause an RPATH entry to be added to the final binary, which some tools didn't like). Thanks to Dominique Leuenberger for the suggestion. * open-vm-tools now properly detects PAM and enables PAM support in the code. open-vm-tools 2009.04.23 changes: * Implemented copy & paste support for RTF data and file contents. * guestd has been removed from open-vm-tools; vmtoolsd is now the only option for the main tools service. * Added vmblock and vmmemctl modules for Solaris (under the CDDL). * vmware-user can now work with both vmblock-fuse and vmblock. * Linux HGFS now has a stream-based (TCP, vsock) transport, still under development. * First batch of changes to cleanup duplicated files in the source tree. Most duplicated files in the Linux kernel modules have been cleaned up. open-vm-tools 2009.03.18 changes: * Mostly a bug fix release. * Solaris vmxnet3 driver was added; open-vm-tools now should also compile on OpenSolaris (tested on 08.11), as long as the --without-gtkmm option is used. * The new DnD V3 protocol is now available in open-vm-tools. * Added "rpctool", a simple, stand-alone tool to send RPC commands to the host software. * vmtoolsd is now preferred in lieu of vmware-guestd; vmware-guestd will most probably be completely removed in the next release. open-vm-tools 2009.02.18 changes: * open-vm-tools now depend on glib 2.6.0 as a minimum requirement. * Added vmxnet module for Solaris, and reworked the HGFS module so it works without help from vmware-guestd. * Added implementation of new DnD protocol, which adds a dependency on a C++ compiler and the gtkmm library to vmware-user. * The code from the "core services" has been added to open-vm-tools, including a few tests. vmtoolsd + plugins are now capable of replacing vmware-guestd (vmware-user still needs to have some features ported over), but this code is still not to be considered as stable as the legacy services, so vmware-guestd is still included. * A few fixes for compatibility with non-GNU toolchains, newer Linux kernels and old gcc compilers. open-vm-tools 2009.01.21 changes: * First open source release of the HGFS module for Solaris, under the CDDL. Other modules are expected to be added in the upcoming releases. * Added an implementation of vmblock on top of FUSE; vmware-user still doesn't use this module even if it is available, though. * Linux modules now add the "supported" tag used by Novell in their SLES 10 SP2 release when loading modules. * Fix compilation of modules in newer Linux kernels which don't include $(LINUXINCLUDE) in the compiler flags anymore. open-vm-tools 2008.12.23 changes: * Lots of makefile cleanup with the switch to using libtool archives. * Automatically disable Unity if multimon support is disabled. * Actually build the pvscsi modules. * First bits of the "Core Service" project are starting to show up; the base "vmtools" library was added to the package. It currently is mostly a collection of the existing libraries already shipped with open-vm-tools, plus some extra functionality build on top of glib. Currently no other code in open-vm-tools uses it, so it's optional. * The HGFS driver was fixed for the Linux 2.6.28 kernel. open-vm-tools 2009.11.18 changes: * The pvscsi Linux kernel module has been added (for kernels >= 2.6.8). It provides access to VMware's new paravirtualized SCSI device. * The HGFS driver and user-level code has seen a lot of refactoring to enable more consistent name escaping. The FreeBSD driver now supports symlinks. * The Linux module makefiles now support exporting symbol version files, allowing modules with dependencies (such as vsock, which depends on vmci) to correctly build and load on Linux >= 2.6.26 with CONFIG_MODVERSIONS. * Rudimentary support for dkms. * Assortment of bug fixes. open-vm-tools 2009.10.13 changes: * The vmxnet3 Linux kernel module has been added. This module provides better network performance for the guest. The corresponding virtual hardware is available beginning with Workstation 6.5, though performance benefits are unlikely to be realized until a later VMware product release. The module should work for all kernels beginning with 2.6. * The open-vm-tools no longer depend on libproc-dev. Several people reported this issue (Sourceforge bug 1960947). * Added a command line argument to skip privileged operations during make install (--without-root-privileges). * Guestd now supports backwards time synchronization, though the corresponding hypervisor-side changes are not yet part of any shipping VMware products. * Assortment of bug fixes. open-vm-tools 2009.09.03 changes: * Fixed an issue where open-vm-tools fails to configure when using --without-icu. Thanks to Timo Gurr for reporting the issue (Sourceforge bug 2046262). * Fixed failed build on Ubuntu Intrepid and Fedora 9. Thanks to Nathan Charles for reporting the issue (Sourceforge bug 2048423). * Fixed kernel module build issues on 2.6.27 pre-release kernels. Thanks to Dominique Leuenberger for reporting the issue (Sourceforge bug 2071170). * ...and other bug fixes. open-vm-tools 2008.08.08 changes: * Unity for X11 guests has been added. Unity is implemented within vmware-user and requires no additional setup beyond setting up the vmware-user application itself. Unity should work with Fusion 1.x releases as well as with the upcoming Workstation 6.5 release. Our in-house testing was with Linux guests, and they should mostly work. There is very little standing in the way of FreeBSD/Solaris support, though we've never built or tested Unity for those platforms. * The VMCI Linux kernel module has been added. This module provides high-speed datagram and socket interfaces for guest<->guest and host<->guest communication. It should work for all kernels beginning with 2.4, and for VMware products beginning with Workstation 6.5. * The VMCI sockets Linux kernel module has been added. It provides both datagram and stream socket interfaces to userlevel for use with VMCI. As with VMCI, it should work for kernels 2.4 or later, and for VMware products beginning with Workstation 6.5. * The command-line Toolbox has been added. This application provides the same functionality as the GTK Toolbox, but with a scriptable command-line interface. It also has some statistic retrieval commands that aren't found in the GTK Toolbox. * Fixed compilation of vmsync and vmmemctl Linux kernel modules on 2.6.26. Thanks to Pavol Rusnak for the report (Sourceforge bug 2032683). * Fixed an issue with guestd's nicInfo updating mechanism. Thanks to Jason Lunz for the patch (not tracked on Sourceforge). * Fixed handling of $(DESTDIR) in automake. Thanks to Mike Auty for the patch (Sourceforge bug 2018802). * Fixed build of vmware-user using gtk 1.2. Thanks to Stephen Duncan for the report (Sourceforge bug 2014338). * Fixed compilation of lib/guestApp when using --without-x. Thanks to Martin Preishuber for the report (Sourceforge bug 2013568). * As usual, other bug fixes. open-vm-tools 2008.07.01 changes: * Fixed a backwards time synchronization issue (not tracked on Sourceforge). Thanks to Eric Castan for reporting it. * Fixed an issue where open-vm-tools configured via --without-x didn't compile (not tracked on Sourceforge). Thanks to Mark Foster for reporting the bug. * Other bug fixes. open-vm-tools 2008.06.20 changes: * Fixed Sourceforge bug 1847750 (FreeBSD 7 & 8 builds) and Sourceforge bug 1981632 (build failure on Solaris). This should get open-vm-tools building and running on FreeBSD 7 & 8 and Solaris. Thanks to Martin Blapp for all the FreeBSD patches, and Jonathan Keatley for reporting the Solaris bug. * Fixed Sourceforge bug 1968416 (packet counting in FreeBSD vmxnet). Thanks to Shunsuke SHINOMIYA for reporting this bug. * Fixed Sourceforge bug 1983375 (Cannot specify kernel constraints). You can now pass --without-kernel-modules, --with-kernel-release, and --with-linuxdir to the ./configure script. Thanks to Craig Phillips for reporting this bug. * Other bug fixes. open-vm-tools 2008.06.03 changes: * Added the vmware-user-suid-wrapper application, with implementations for Linux, FreeBSD, and Solaris. This app is needed to make correct use of vmware-user with the vmblock kernel module. It should have been in the previous code refresh, but we accidentally overlooked it. * Fixed Sourceforge bug 1924246: vmhgfs on Linux properly reports the available space on the host. Thanks to Mikhail Krivtsov for reporting the bug. * Fixed Sourceforge bug 1839981: we now have rudimentary `make install` support. On any platform, it should copy files and kernel modules to the location specified at build-time, and on Linux, it will additionally run `depmod -a` to make the kernel modules accessible to modprobe. This change also adds a "--with-pam-prefix" argument to the configure script, which controls the location of guestd's pam files. * Other bug fixes. open-vm-tools 2008.05.15 changes: * guestd no longer starts vmware-user. Packagers will need to use the XDG autostart spec, Xsession drop-in scripts, or other appropriate mechanisms to make sure that vmware-user is started as part of X session initialization. Please see http://open-vm-tools.wiki.sourceforge.net/Packaging for more details. * Bug fixes as usual. open-vm-tools 2008.05.02 changes: * Continued Unicode support. * open-vm-tools now depends on libicu for codeset conversions. If you wish to build open-vm-tools without libicu, pass "--without--icu" when configuring the package. Without libicu, codeset conversions will be done as before, via calls to iconv. * A few more bug fixes. open-vm-tools 2008.04.14 changes: * Update the license stamp on all LGPL files. * Continued Unicode support. * Handle libdumbnet on Debian. * More bug fixes, including a security fix in guestd. open-vm-tools 2008.03.19 changes: * Continued Unicode support. * A few bug fixes. open-vm-tools 2008.03.03 changes: * Bug fixes (including the ability to specify custom LDFLAGS at build time, thanks to Mike Auty). * First cut of HGFSv3 implementation. * Beginnings of DnDv3 implementation. * Add Unicode support all over the code base. open-vm-tools 2008.02.13 changes: * Some bug fixes. open-vm-tools 2008.01.23 changes: * The Linux HGFS kernel module now supports writeback caching, which should yield better performance. * Added a generic Unicode-aware library to ease i18n and l10n work. * A bunch of bug fixes. open-vm-tools 2007.11.15 "Bandsaw" changes: * Kernel modules for FreeBSD, including an experimental port of HGFS to FreeBSD. * Add the vmsync driver on Linux to make VM snapshots consistent. * Added the xferlogs utility, the *-vm-default scripts, and the vm-support script. * Build on a wider variety of systems. * Lots of smaller bug fixes throughout the code. open-vm-tools 2007.09.04 "Axe" changes: * Initial release of open-vm-tools. open-vm-tools-stable-12.5.0/open-vm-tools/README000066400000000000000000000003051470176644300211770ustar00rootroot00000000000000This file is no longer distributed with open-vm-tools.

This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This module provides functions for writing "debug plugins" - plugins which provide functionality for driving the Tools Services when they're running in "debug mode". Debug plugins are dynamically loaded by providing specific command-line options to the Tools service process. @section vmtools_debug_how How debug plugins work Currently, there's only support for GuestRPC-based debug plugins. The debug library implements an RPC channel that can be driven by a debug plugin, according to information provided by the plugin at load time. The debug plugin can provide two types of information: - RPCs to be sent to the application: these are input to the application, and can be tied to a validation function to make sure the response from the application is correct. - Validation functions for "outgoing" RPCs: these are functions called in response to RPCs initiated by the applications; they can be mapped to specific RPC command strings, to make writing the plugin easier. For more details, check the RpcDebugPlugin data structure. Plugins that depend on events that are not only responses to RPC messages (such as timer-based outgoing RPCs) should make sure they tell the library that it should not stop running by incrementing its ref count (see RpcDebug_IncRef()). When the test is complete, the code can then call RpcDebug_DecRef() and, when the ref count reaches zero, the main application loop will be stopped. */ open-vm-tools-stable-12.5.0/open-vm-tools/docs/api/services/guestrpc.txt000066400000000000000000000031111470176644300262360ustar00rootroot00000000000000/********************************************************* * Copyright (C) 2008-2016 VMware, Inc.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Memory * allocations are kept to a minimum to ensure that this is appropriate for * use in a kernel mode driver. Linear probing is used to resolve hash * collisions. * * This implementation only supports static length keys. It might be * possible to store the keys outside the table and thus support keys of * variable length but this isn't currently planned. This would allow for * string keys for example. * * Callers should not store pointers to objects stored in the map as they may * become invalid as a result of a resize. If you need to share objects * stored as values in the map, then store pointers to the objects instead. * * All objects are copied into the map and must be freed as appropriate by * the caller. * * This particular HashMap has some important differences from the hash table * implementation in bora/lib/misc * - HashMap supports key removal * - HashMap only supports fixed size keys and values while hashTable * supports string and insensitive string keys and only supports pointer * data. This means its possible to store entire data structures in * HashMap. * - HashMap uses linear probing to resolve collisions while hashTable uses * chaining. HashMap will dynamically resize itself as necessary. * - Pointers to HashMap values will be invalidated if the internal structure * is resized. If this is a problem, you should store the pointer in the * HashMap rather than the object itself. * - HashMap will ensure that a maximum load factor is not exceeded. * * hashMap is now restrictd to userworld applications on ESX builds ONLY. * See PR 817760 which has an attached patchfile to remove this limitation * if in future that is felt to be desireable. */ #define HASHMAP_DEFAULT_ALPHA 2 struct HashMap { uint8 *entries; uint32 numEntries; uint32 count; uint32 alpha; size_t keySize; size_t dataSize; size_t entrySize; size_t keyOffset; size_t dataOffset; }; #ifdef VMX86_SERVER #pragma pack(push, 1) typedef struct HashMapOnDisk { uint32 numEntries; uint32 count; uint32 alpha; uint64 keySize; uint64 dataSize; uint64 entrySize; uint64 keyOffset; uint64 dataOffset; } HashMapOnDisk; #pragma pack(pop) #endif typedef enum { HashMapState_EMPTY = 0, HashMapState_FILLED, HashMapState_DELETED, } HashMapEntryState; typedef struct { uint32 state; uint32 hash; } HashMapEntryHeader; #define NO_FREE_INDEX ((uint32) -1) static Bool InitMap(struct HashMap *map, uint32 numEntries, uint32 alpha, size_t keySize, size_t dataSize); static void CalculateEntrySize(struct HashMap *map); static void GetEntry(struct HashMap *map, uint32 index, HashMapEntryHeader **header, void **key, void **data); static uint32 ComputeHash(struct HashMap *map, const void *key); static Bool LookupKey(struct HashMap* map, const void *key, Bool constTimeLookup, HashMapEntryHeader **header, void **data, uint32 *freeIndex); static Bool CompareKeys(struct HashMap *map, const void *key, const void *compare); static Bool ConstTimeCompareKeys(struct HashMap *map, const void *key, const void *compare); static Bool NeedsResize(struct HashMap *map); static void Resize(struct HashMap *map); INLINE void EnsureSanity(HashMap *map); /* * ---------------------------------------------------------------------------- * * CheckSanity -- * * Same code as EnsureSanity except return Bool instead of ASSERTing * * Results: * TRUE is sane. * * Side Effects: * None. * * ---------------------------------------------------------------------------- */ #ifdef VMX86_DEBUG static INLINE Bool CheckSanity(HashMap *map) { uint32 i, cnt = 0; ASSERT(map); for (i = 0; i < map->numEntries; i++) { HashMapEntryHeader *header = NULL; void *key, *data; GetEntry(map, i, &header, &key, &data); ASSERT(header); ASSERT(header->state == HashMapState_FILLED || header->state == HashMapState_EMPTY || header->state == HashMapState_DELETED); if (header->state == HashMapState_FILLED) { cnt++; if (header->hash != ComputeHash(map, key)) { return FALSE; } } } if (cnt != map->count) { return FALSE; } if (!map->numEntries) { return FALSE; } return TRUE; } #endif /* * ---------------------------------------------------------------------------- * * HashMap_AllocMap -- * * Allocate a map and the space for the entries. * * Results: * Returns a pointer to a HashMap or NULL on failure. * * Side Effects: * Allocates memory. * * ---------------------------------------------------------------------------- */ struct HashMap* HashMap_AllocMap(uint32 numEntries, // IN size_t keySize, // IN size_t dataSize) // IN { return HashMap_AllocMapAlpha(numEntries, HASHMAP_DEFAULT_ALPHA, keySize, dataSize); } /* * ---------------------------------------------------------------------------- * * HashMap_AllocMapAlpha -- * * Allocate a map and the space for the entries.

A + N ). * * o A vCPU can access the I/O space when running 32-bit or 64-bit code. * * o A vCPU running in unprivileged mode can use the backdoor. * * As a result, VMware virtual device drivers that were initially developed for * x86 can trivially be ported to arm. * * Mechanism * --- * In this section, we call W the 32-bit register which aliases the low 32 * bits of the 64-bit register X. * * A vCPU which wishes to use the "VMware x86 I/O space virtualization on arm" * must follow these 4 steps: * * 1) Write to general-purpose registers specific to the x86 I/O space * instruction. * * The vCPU writes to the arm equivalent of general-purpose x86 registers (see * the BDOOR_ARG* mapping below) that are used by the x86 I/O space instruction * it is about to perform. * * Examples: * o For an IN instruction without DX register, there is nothing to do. * o For an OUT instruction with DX register, the vCPU places the I/O port * address in bits W3<15:0> and the value to write in W0<7:0> (1 byte access) * or W0<15:0> (2 bytes access) or W0 (4 bytes access). * o For an REP OUTS instruction, the vCPU places the I/O port address in bits * W3<15:0>, the source virtual address in W4 (32-bit code) or X4 (64-bit * code) and the number of repetitions in W2 (32-bit code) or X2 (64-bit * code). * * 2) Write the x86 I/O space instruction to perform. * * The vCPU sets a value in W7, as described below: * * Transfer size, bits [1:0] * 00: 1 byte * 01: 2 bytes * 10: 4 bytes * 11: Invalid value * * Transfer direction, bit [2] * 0: Write (OUT/OUTS/REP OUTS instructions) * 1: Read (IN/INS/REP INS instructions) * * Instruction type, bits [4:3] * 00: Non-string instruction (IN/OUT) without DX register * The port address (8-bit immediate) is set in W7<12:5>. * * 01: Non-string instruction (IN/OUT) with DX register * * 10: String instruction without REP prefix (INS/OUTS) * The direction flag (EFLAGS.DF) is set in W7<5>. * * 11: String instruction with REP prefix (REP INS/REP OUTS) * The direction flag (EFLAGS.DF) is set in W7<5>. * * All other bits not described above are reserved for future use and must be * set to 0. * * 3) Perform the x86 I/O space instruction. * * Several mechanisms are available: * * o From EL1 * The vCPU executes the HVC instruction with the immediate X86_IO_MAGIC. * * This is the mechanism to favor from EL1 because it is architectural. * * o From EL1 and EL0 * The vCPU sets X7<63:32> to X86_IO_MAGIC and executes the * MRS XZR, MDCCSR_EL0 instruction. * * This is the mechanism to favor from EL0 because it has a negligible impact * on vCPU performance. * * o From EL1 and EL0, only when monitor_control.hv_hypercall = "TRUE" * The vCPU executes the BRK instruction with the immediate X86_IO_MAGIC. * * Pro: This mechanism cannot be intercepted by EL3 code. * Con: This mechanism has a significant impact on vCPU performance when * running a debugger in the guest. * * 4) Read from general-purpose registers specific to the x86 I/O space * instruction. * * The vCPU reads from the arm equivalent of general-purpose x86 registers (see * the BDOOR_ARG* mapping below) that are used by the x86 I/O space instruction * it has just performed. * * Examples: * o For an OUT instruction, there is nothing to do. * o For an IN instruction, retrieve the value that was read from W0<7:0> (1 * byte access) or W0<15:0> (2 bytes access) or W0 (4 bytes access). */ #define X86_IO_MAGIC 0x86 #define X86_IO_W7_SIZE_SHIFT 0 #define X86_IO_W7_SIZE_MASK (0x3 << X86_IO_W7_SIZE_SHIFT) #define X86_IO_W7_DIR (1 << 2) #define X86_IO_W7_WITH (1 << 3) #define X86_IO_W7_STR (1 << 4) #define X86_IO_W7_DF (1 << 5) #define X86_IO_W7_IMM_SHIFT 5 #define X86_IO_W7_IMM_MASK (0xff << X86_IO_W7_IMM_SHIFT) #define BDOOR_ARG0 REG_X0 #define BDOOR_ARG1 REG_X1 #define BDOOR_ARG2 REG_X2 #define BDOOR_ARG3 REG_X3 #define BDOOR_ARG4 REG_X4 #define BDOOR_ARG5 REG_X5 #define BDOOR_ARG6 REG_X6 #else #define BDOOR_ARG0 REG_RAX #define BDOOR_ARG1 REG_RBX #define BDOOR_ARG2 REG_RCX #define BDOOR_ARG3 REG_RDX #define BDOOR_ARG4 REG_RSI #define BDOOR_ARG5 REG_RDI #define BDOOR_ARG6 REG_RBP #endif #if defined __cplusplus } #endif #endif // _BACKDOOR_DEF_H_ open-vm-tools-stable-12.5.0/open-vm-tools/lib/include/backdoor_types.h000066400000000000000000000107161470176644300257000ustar00rootroot00000000000000/********************************************************* * Copyright (C) 1999-2016,2019 VMware, Inc.

Both the level 1 and * batch oplocks are "exclusive access" opens. They are used slightly differently, * however, and hence have somewhat different semantics. A level 2 oplock is a "shared * access" grant on the file. * Level 1 is used by a remote client that wishes to modify the data. Once granted a * Level 1 oplock, the remote client may cache the data, modify the data in its cache * and need not write it back to the server immediately. * Batch oplocks are used by remote clients for accessing script files where the file is * opened, read or written, and then closed repeatedly. Thus, a batch oplock * corresponds not to a particular application opening the file, but rather to a remote * clients network file system caching the file because it knows something about the * semantics of the given file access. The name "batch" comes from the fact that this * behavior was observed by Microsoft with "batch files" being processed by command line * utilities. Log files especially exhibit this behavior when a script it being * processed each command is executed in turn. If the output of the script is redirected * to a log file the file fits the pattern described earlier, namely open/write/close. * With many lines in a file this pattern can be repeated hundreds of times. * Level 2 is used by a remote client that merely wishes to read the data. Once granted * a Level 2 oplock, the remote client may cache the data and need not worry that the * data on the remote file server will change without it being advised of that change. * An oplock must be broken whenever the cache consistency guarantee provided by the * oplock can no longer be provided. Thus, whenever a second network client attempts to * access data in the same file across the network, the file server is responsible for * "breaking" the oplocks and only then allowing the remote client to access the file. * This ensures that the data is guaranteed to be consistent and hence we have preserved * the consistency guarantees essential to proper operation. * * HGFS_OPLOCK_NONE: no oplock. No caching on client side. * HGFS_OPLOCK_SHARED: shared (or LEVEL II) oplock. Read caching is allowed. * HGFS_OPLOCK_EXCLUSIVE: exclusive (or LEVEL I) oplock.

Atomicity of the access itself * 2. Ordering of the access with respect to other reads&writes (from the view * of other processors/devices). * * Two examples help to clarify #2: * a. Inc: A caller implementing a simple independent global event counter * might not care if the compiler or processor visibly reorders the * increment around other memory accesses. * b. Dec: A caller implementing a reference count absolutely *doesn't* want * the compiler or processor to visibly reordering writes after that * decrement: if that happened, the program could then end up writing * to memory that was freed by another processor. * * C11 has standardized a good model for expressing these orderings when doing * atomics. It defines three *tiers* of ordering: * 1. Sequential Consistency (every processor sees the same total order of * events) * * 2. Acquire/Release ordering (roughly, everybody can agree previous events * have completed, but they might disagree on the ordering of previous * independent events). * * The relative ordering provided by this tier is sufficient for common * locking and initialization activities, but is insufficient for unusual * synchronization schemes (e.g. IRIW aka Independent Read Independent * Write designs such Dekker's algorithm, Peterson's algorithm, etc.) * * In other words, this tier is close in behavior to Sequential Consistency * in much the same way a General-Relativity universe is close to a * Newtonian universe. * 3. Relaxed (i.e unordered/unfenced) * * In C11 standard's terminology for atomic memory ordering, * - in case (a) we want "relaxed" ordering for perf and, * - in case (b) we want "sequentially consistent" ordering (or perhaps the * only slightly weaker "release" ordering) for correctness. * * There are standardized mappings of operations to orderings for every * processor architecture. See * - https://www.cl.cam.ac.uk/~pes20/cpp/cpp0xmappings.html * - http://preshing.com/20120913/acquire-and-release-semantics/ * * In this file: * 1. all RMW (Read/Modify/Write) operations are sequentially consistent. * This includes operations like Atomic_IncN, Atomic_ReadIfEqualWriteN, * Atomic_ReadWriteN, etc. * 2. all R and W operations are relaxed. This includes operations like * Atomic_WriteN, Atomic_ReadN, Atomic_TestBitN, etc. * * The below routines of course ensure both the CPU and compiler honor the * ordering constraint. * * Notes: * 1. Since R-only and W-only operations do not provide ordering, callers * using them for synchronizing operations like double-checked * initialization or releasing spinlocks must provide extra barriers. * 2. This implementation of Atomic operations is suboptimal. On x86,simple * reads and writes have acquire/release semantics at the hardware level. * On arm64, we have separate instructions for sequentially consistent * reads and writes (the same instructions are used for acquire/release). * Neither of these are exposed for R-only or W-only callers. * * For further details on x86 and ARM memory ordering see * https://wiki.eng.vmware.com/ARM/MemoryOrdering. */ #ifdef VM_ARM_64 # include "vm_atomic_arm64_begin.h" #endif /* Basic atomic types: 8, 16, 32, 64 and 128 bits */ typedef ALIGNED(1) struct Atomic_uint8 { volatile uint8 value; } Atomic_uint8; typedef ALIGNED(2) struct Atomic_uint16 { volatile uint16 value; } Atomic_uint16; typedef ALIGNED(4) struct Atomic_uint32 { volatile uint32 value; } Atomic_uint32; typedef ALIGNED(8) struct Atomic_uint64 { volatile uint64 value; } Atomic_uint64; #ifdef VM_HAS_INT128 typedef ALIGNED(16) struct Atomic_uint128 { volatile uint128 value; } Atomic_uint128; #endif #if defined __arm__ /* * LDREX without STREX or CLREX may cause problems in environments where the * context switch may not clear the reference monitor - according ARM manual * the reference monitor should be cleared after a context switch, but some * may not like Linux kernel's non-preemptive context switch path.
