Each srp_daemon instance operates on one local port. Upon boot it performs a full rescan of the fabric then waits for an srp_daemon event. An srp_daemon event can be a join of a new machine to the fabric, a change in the capabilities of a machine, an SA change, or an expiration of a predefined timeout. When a new machine joins the fabric, srp_daemon checks if it is a target. When there is a change of capabilities, srp_daemon checks if the machine has turned into a target. When there is an SA change or a timeout expiration, srp_daemon performs a full rescan of the fabric. For each target srp_daemon finds, it checks if it should connect to this target according to its rules (default rules file is /etc/srp_daemon.conf) and if it is already connected to the local port. If it should connect to this target and if it is not connected yet, srp_daemon can either print the target details or connect to it. .SH OPTIONS .PP .TP \fB\-v\fR Print more verbose output .TP \fB\-V\fR Print even more verbose output (debug mode) .TP \fB\-i\fR \fIinfiniband-device\fR Work on \fIinfiniband-device\fR. This option should not be used with -d. .TP \fB\-p\fR \fIport-num\fR Work on port \fIport-num\fR (default 1). This option must be used with -i and should not be used with -d. .TP \fB\-d\fR \fIumad-device\fR Use device file \fIumad-device\fR (default /dev/infiniband/umad0) This option should not be used with -i or -p. .TP \fB\-c\fR Generate output suitable for piping directly to a /sys/class/infiniband_srp/srp\-\-/add_target file. .TP \fB\-a\fR Prints all the targets in the fabric, not only targets that are not connected through the local port. (The same as ibsrpdm.) .TP \fB\-e\fR Execute the connection command, i.e., make the connection to the target. .TP \fB\-o\fR Perform only one rescan and exit. (The same as ibsrpdm.) .TP \fB\-R\fR \fIRescan-time\fR Force a complete rescan every \fIRescan-time\fR seconds. If -R is not specified, no timeout rescans will be performed. .TP \fB\-T\fR \fIretry-Timeout\fR Retries to connect to existing target after \fIretry-Timeout\fR seconds. If -R is not specified, uses 5 Seconds timeout. if retry-Timeout is 0, will not try to reconnect. The reason srp_daemon retries to connect to the target is because there may be a rare scnerio in which srp_daemon will try to connect to add a target when the target is about to be removed, but is not removed yet. .TP \fB\-f\fR \fIrules-File\fR Decide to which targets to connect according to the rules in \fIrules-File\fR. If \fB\-f\fR is not specified, uses the default rules file /etc/srp_daemon.conf. Each line in the \fIrules-File\fR is a rule which can be either an allow connection or a disallow connection according to the first character in the line (a or d accordingly). The rest of the line is values for id_ext, ioc_guid, dgid, service_id. Please take a look at the example section for an example of the file. srp_daemon decide whether to allow or disallow each target according to first rule that match the target. If no rule matches the target, the target is allowed and will be connected. In an allow rule it is possible to set attributes for the connection to the target. Supported attributes are max_cmd_per_lun and max_sect. .TP \fB\-t\fR \fItimeout\fR Use timeout of \fItimeout\fR msec for MAD responses (default: 5 sec). .TP \fB\-r\fR \fIretries\fR Perform \fIretries\fR retries on each send to MAD (default: 3 retries). .TP \fB\-n\fR New format - use also initiator_ext in the connection command. .SH FILES /etc/srp_daemon.conf - Default rules configuration file that indicates to which targets to connect. Can be overridden using the \fB\-f\fR \fIrules-File\fR option. Each line in this file is a rule which can be either an allow connection or a disallow connection according to the first character in the line (a or d accordingly). The rest of the line is values for id_ext, ioc_guid, dgid, service_id. Please take a look at the example section for an example of the file. srp_daemon decide whether to allow or disallow each target according to first rule that match the target. If no rule matches the target, the target is allowed and will be connected. In an allow rule it is possible to set attributes for the connection to the target. Supported attributes are max_cmd_per_lun and max_sect. .SH EXAMPLES srp_daemon -e -i mthca0 -p 1 -R 60 (Connects to the targets accessible through port 1 of mthca0. Performs a complete rescan every minute) srp_daemon -o -c -a (Prints the connection commands for the targets in the fabric and exits - similar to ibsrpdm) srp_daemon -e -f rules.txt (Connects to the targets allowed in the rules file rules.txt) .nf An example for a rules configuration file (such as /etc/srp_daemon.conf) ------------------------------------------------------------------------ # Rules file example # This is a comment # disallow the following dgid d dgid=fe800000000000000002c90200402bd5 # allow target with the following ioc_guid a ioc_guid=00a0b80200402bd7 # allow target with the following id_ext and ioc_guid.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

These targets can be accessed with the InfiniBand SRP initiator module, "ib_srp," included in Linux kernels 2.6.15 and newer. Using srptools ============== srptools currently contains only a single executable, ibsrpdm. To run ibsrpdm, the ib_umad module must be loaded, as well as an appropriate low-level driver for the installed IB hardware -- for example, ib_mthca for a Mellanox HCA, ib_ipath for a QLogic HCA, or hcad_mod for an IBM eHCA. With no command line parameters, ibsrpdm displays information about SRP targets in human-readable form: # ibsrpdm IO Unit Info: port LID: 0009 port GID: fe800000000000000005ad00000013e9 change ID: 73b0 max controllers: 0x01 controller[ 1] GUID: 0005ad00000013e7 vendor ID: 0005ad device ID: 0005ad IO class : 0100 ID: Topspin SRP/FC TCA service entries: 2 service[ 0]: 0000000000000066 / SRP.T10:20030003BA27CC7A service[ 1]: 0000000000000066 / SRP.T10:20030003BA27CF53 With the "-c" flag, ibsrpdm displays information in a form that can be written to the kernel SRP initiators add_target file to connect to the SRP targets. For example: # ibsrpdm -c id_ext=20030003BA27CC7A,ioc_guid=0005ad00000013e7,dgid=fe800000000000000005ad00000013e9,pkey=ffff,service_id=0000000000000066 id_ext=20030003BA27CF53,ioc_guid=0005ad00000013e7,dgid=fe800000000000000005ad00000013e9,pkey=ffff,service_id=0000000000000066 Given this, the command below will connect to the first target discovered from the first port of the local HCA device "mthca0": # echo -n id_ext=20030003BA27CC7A,ioc_guid=0005ad00000013e7,dgid=fe800000000000000005ad00000013e9,pkey=ffff,service_id=0000000000000066 > /sys/class/infiniband_srp/srp-mthca0-1/add_target Reporting bugs ============== Bugs should be reported to the OpenIB mailing list . In your bug report, please include: * Information about your system: - Linux distribution and version - Linux kernel and version - InfiniBand hardware and firmware version - ... any other relevant information * How to reproduce the bug. * If the bug is a crash, the exact output printed out when the crash occurred, including any kernel messages produced. Submitting patches ================== Patches should also be submitted to the OpenIB mailing list . Please use unified diff form (the -u option to GNU diff), and include a good description of what your patch does and why it should be applied. If your patch fixes a bug, please make sure to describe the bug and how your fix works. Please include a change to the ChangeLog file (in standard GNU changelog format) as part of your patch.

It can also ask ib_srp module to connect to these targets. * Makefile.am: Was changed to call to srp_daemon Makefile. * Configure.in: Was changed to include srp_daemon. 2006-07-01 Roland Dreier * src/srp-dm.c (get_node): Use correct attribute ID to retrieve NodeRecord -- old code incorrectly queried for a PortInfoRecord. 2006-06-14 Roland Dreier * src/srp-dm.c: Add support for SMs that support queries of PortInfo that match only specified bits in the CapabilityMask. This will be more efficient on large fabrics, since only ports with the IsDM bit will be queried, instead of retrieving the full node record table for the full fabric. * src/srp-dm.h: Change SRP_DM_ATTR_CLASS_PORT_INFO to SRP_ATTR_CLASS_PORT_INFO, since it is not a per-class value. * src/srp-dm.c: Change agent array into a single value, since only the QP1 agent is ever used. 2006-06-08 Roland Dreier * src/srp-dm.c (get_port_list): In some setups (eg Cisco SFS 3001 with an FC gateway), there will be switches with the IsDM bit set on port 0. So the initial get of NodeRecords must retrieve all records, not just CA ports. 2006-06-07 Roland Dreier * src/srp-dm.c (do_port): Use correct endianness when comparing GUID against Topspin OUI. * src/srp-dm.c (set_class_port_info): Trivial whitespace fixes. 2006-05-29 Ishai Rabinovitz * src/srp-dm.c (main): The agent ID array is declared with 0 entries, which leads to corruption when it is filled in by create_agent(). Fix that by declaring it with the correct number of entries, 2. 2006-04-10 Roland Dreier * configure.in: srptools no longer needs to check for libsysfs. * src/srp-dm.c: Remove use of libsysfs -- just read directly to get what we need. Make functions static, since they are only used in one file. 2006-01-18 Yael Shenhav * src/ib_user_mad.h: Use __u16/__u32 instead of __be16/__be32, since not all toolchains export __beXX types to userspace. 2006-01-17 Roland Dreier * Release as version 0.03 trunk/COPYING0000644000175000017500000004645711313644723012622 0ustar benoitbenoitThis software is available to you under a choice of one of two licenses.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, 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 or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. 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. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. 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 program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program 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 General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.
