The kmem SLAB * allocator allocates slabs from it. Then the generic allocation functions * kmem_{alloc,zalloc,free}() are layered on top of SLAB allocators. * * On Linux, the primary means of doing allocations is via kmalloc(), which * is similarly layered on top of something called the buddy allocator. The * buddy allocator is not available to kernel modules, it uses physical * memory addresses rather than virtual memory addresses and is prone to * fragmentation. * * Linux sets aside a relatively small address space for in-kernel virtual * memory from which allocations can be done using vmalloc(). It might seem * like a good idea to use vmalloc() to implement something similar to * Illumos' allocator. However, this has the following problems: * * 1. Page directory table allocations are hard coded to use GFP_KERNEL. * Consequently, any KM_PUSHPAGE or KM_NOSLEEP allocations done using * vmalloc() will not have proper semantics. * * 2. Address space exhaustion is a real issue on 32-bit platforms where * only a few 100MB are available. The kernel will handle it by spinning * when it runs out of address space. * * 3. All vmalloc() allocations and frees are protected by a single global * lock which serializes all allocations. * * 4. Accessing /proc/meminfo and /proc/vmallocinfo will iterate the entire * list. The former will sum the allocations while the latter will print * them to user space in a way that user space can keep the lock held * indefinitely. When the total number of mapped allocations is large * (several 100,000) a large amount of time will be spent waiting on locks. * * 5. Linux has a wait_on_bit() locking primitive that assumes physical * memory is used, it simply does not work on virtual memory. Certain * Linux structures (e.g. the superblock) use them and might be embedded * into a structure from Illumos. This makes using Linux virtual memory * unsafe in certain situations. * * It follows that we cannot obtain identical semantics to those on Illumos. * Consequently, we implement the kmem_{alloc,zalloc,free}() functions in * such a way that they can be used as drop-in replacements for small vmem_* * allocations (8MB in size or smaller) and map vmem_{alloc,zalloc,free}() * to them. */ #define vmem_alloc(sz, fl) spl_vmem_alloc((sz), (fl), __func__, __LINE__) #define vmem_zalloc(sz, fl) spl_vmem_zalloc((sz), (fl), __func__, __LINE__) #define vmem_free(ptr, sz) spl_vmem_free((ptr), (sz)) #define vmem_qcache_reap(ptr) ((void)0) extern void *spl_vmem_alloc(size_t sz, int fl, const char *func, int line); extern void *spl_vmem_zalloc(size_t sz, int fl, const char *func, int line); extern void spl_vmem_free(const void *ptr, size_t sz); int spl_vmem_init(void); void spl_vmem_fini(void); #endif /* _SPL_VMEM_H */ spl-0.7.5/include/sys/dirent.h0000644016037001603700000000237013216017324013152 00000000000000/*****************************************************************************\ * Copyright (C) 2007-2010 Lawrence Livermore National Security, LLC. * Copyright (C) 2007 The Regents of the University of California. * Produced at Lawrence Livermore National Laboratory (cf, DISCLAIMER). * Written by Brian Behlendorf . * UCRL-CODE-235197 * * This file is part of the SPL, Solaris Porting Layer. * For details, see . * * The SPL 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. * * The SPL 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.

The idea is that objects in magazines which have not been recently accessed should be returned to the slabs periodically. This is known as cache aging and when enabled objects will be typically returned after 15 seconds. .sp On the other hand Linux slabs are designed to never move objects back to the slabs unless there is memory pressure. This is possible because under Linux the cache will be notified when memory is low and objects can be released. .sp By default only the Linux method is enabled. It has been shown to improve responsiveness on low memory systems and not negatively impact the performance of systems with more memory. This policy may be changed by setting the \fBspl_kmem_cache_expire\fR bit mask as follows, both policies may be enabled concurrently. .sp 0x01 - Aging (Illumos), 0x02 - Low memory (Linux) .sp Default value: \fB0x02\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_kmem_threads\fR (uint) .ad .RS 12n The number of threads created for the spl_kmem_cache task queue. This task queue is responsible for allocating new slabs for use by the kmem caches. For the majority of systems and workloads only a small number of threads are required. .sp Default value: \fB4\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_reclaim\fR (uint) .ad .RS 12n When this is set it prevents Linux from being able to rapidly reclaim all the memory held by the kmem caches. This may be useful in circumstances where it's preferable that Linux reclaim memory from some other subsystem first. Setting this will increase the likelihood out of memory events on a memory constrained system. .sp Default value: \fB0\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_obj_per_slab\fR (uint) .ad .RS 12n The preferred number of objects per slab in the cache. In general, a larger value will increase the caches memory footprint while decreasing the time required to perform an allocation. Conversely, a smaller value will minimize the footprint and improve cache reclaim time but individual allocations may take longer. .sp Default value: \fB8\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_obj_per_slab_min\fR (uint) .ad .RS 12n The minimum number of objects allowed per slab. Normally slabs will contain \fBspl_kmem_cache_obj_per_slab\fR objects but for caches that contain very large objects it's desirable to only have a few, or even just one, object per slab. .sp Default value: \fB1\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_max_size\fR (uint) .ad .RS 12n The maximum size of a kmem cache slab in MiB. This effectively limits the maximum cache object size to \fBspl_kmem_cache_max_size\fR / \fBspl_kmem_cache_obj_per_slab\fR. Caches may not be created with object sized larger than this limit. .sp Default value: \fB32 (64-bit) or 4 (32-bit)\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_slab_limit\fR (uint) .ad .RS 12n For small objects the Linux slab allocator should be used to make the most efficient use of the memory. However, large objects are not supported by the Linux slab and therefore the SPL implementation is preferred. This value is used to determine the cutoff between a small and large object. .sp Objects of \fBspl_kmem_cache_slab_limit\fR or smaller will be allocated using the Linux slab allocator, large objects use the SPL allocator. A cutoff of 16K was determined to be optimal for architectures using 4K pages. .sp Default value: \fB16,384\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_kmem_limit\fR (uint) .ad .RS 12n Depending on the size of a cache object it may be backed by kmalloc()'d or vmalloc()'d memory. This is because the size of the required allocation greatly impacts the best way to allocate the memory. .sp When objects are small and only a small number of memory pages need to be allocated, ideally just one, then kmalloc() is very efficient. However, when allocating multiple pages with kmalloc() it gets increasingly expensive because the pages must be physically contiguous. .sp For this reason we shift to vmalloc() for slabs of large objects which which removes the need for contiguous pages. We cannot use vmalloc() in all cases because there is significant locking overhead involved. This function takes a single global lock over the entire virtual address range which serializes all allocations. Using slightly different allocation functions for small and large objects allows us to handle a wide range of object sizes. .sp The \fBspl_kmem_cache_kmem_limit\fR value is used to determine this cutoff size. One quarter the PAGE_SIZE is used as the default value because \fBspl_kmem_cache_obj_per_slab\fR defaults to 16. This means that at most we will need to allocate four contiguous pages. .sp Default value: \fBPAGE_SIZE/4\fR .RE .sp .ne 2 .na \fBspl_kmem_alloc_warn\fR (uint) .ad .RS 12n As a general rule kmem_alloc() allocations should be small, preferably just a few pages since they must by physically contiguous. Therefore, a rate limited warning will be printed to the console for any kmem_alloc() which exceeds a reasonable threshold. .sp The default warning threshold is set to eight pages but capped at 32K to accommodate systems using large pages. This value was selected to be small enough to ensure the largest allocations are quickly noticed and fixed. But large enough to avoid logging any warnings when a allocation size is larger than optimal but not a serious concern. Since this value is tunable, developers are encouraged to set it lower when testing so any new largish allocations are quickly caught. These warnings may be disabled by setting the threshold to zero. .sp Default value: \fB32,768\fR .RE .sp .ne 2 .na \fBspl_kmem_alloc_max\fR (uint) .ad .RS 12n Large kmem_alloc() allocations will fail if they exceed KMALLOC_MAX_SIZE. Allocations which are marginally smaller than this limit may succeed but should still be avoided due to the expense of locating a contiguous range of free pages. Therefore, a maximum kmem size with reasonable safely margin of 4x is set. Kmem_alloc() allocations larger than this maximum will quickly fail. Vmem_alloc() allocations less than or equal to this value will use kmalloc(), but shift to vmalloc() when exceeding this value. .sp Default value: \fBKMALLOC_MAX_SIZE/4\fR .RE .sp .ne 2 .na \fBspl_kmem_cache_magazine_size\fR (uint) .ad .RS 12n Cache magazines are an optimization designed to minimize the cost of allocating memory. They do this by keeping a per-cpu cache of recently freed objects, which can then be reallocated without taking a lock. This can improve performance on highly contended caches. However, because objects in magazines will prevent otherwise empty slabs from being immediately released this may not be ideal for low memory machines. .sp For this reason \fBspl_kmem_cache_magazine_size\fR can be used to set a maximum magazine size. When this value is set to 0 the magazine size will be automatically determined based on the object size. Otherwise magazines will be limited to 2-256 objects per magazine (i.e per cpu). Magazines may never be entirely disabled in this implementation. .sp Default value: \fB0\fR .RE .sp .ne 2 .na \fBspl_hostid\fR (ulong) .ad .RS 12n The system hostid, when set this can be used to uniquely identify a system. By default this value is set to zero which indicates the hostid is disabled.

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 Lesser 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser General Public License instead of this License. spl-0.7.5/Makefile.in0000664016037001603700000011054013216017372011324 00000000000000# Makefile.in generated by automake 1.11.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, # Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ ############################################################################### # Copyright (C) 2007-2013 Lawrence Livermore National Security, LLC. # Copyright (C) 2007 The Regents of the University of California. # Written by Brian Behlendorf . ############################################################################### # Build targets for RPM packages. ############################################################################### ############################################################################### # Copyright (C) 2010 Lawrence Livermore National Security, LLC. # Written by Brian Behlendorf . ############################################################################### # Build targets for DEB packages. # # Long term native distro specific Debian style packaging should be added. # In the short term RPM packages are built and converted to DEB packages # using alien.

It is mapped to /dev/urandom * on Illumos, which uses a "FIPS 186-2 algorithm". No user of the SPL's * random_get_pseudo_bytes() needs bytes that are of cryptographic quality, so * we can implement it using a fast PRNG that we seed using Linux' actual * equivalent to random_get_pseudo_bytes(). We do this by providing each CPU * with an independent seed so that all calls to random_get_pseudo_bytes() are * free of atomic instructions. * * A consequence of using a fast PRNG is that using random_get_pseudo_bytes() * to generate words larger than 128 bits will paradoxically be limited to * `2^128 - 1` possibilities. This is because we have a sequence of `2^128 - 1` * 128-bit words and selecting the first will implicitly select the second.

This is used during tsd_destory() to * quickly call the destructor function for all tsd associated with the key. * The 'key' entry may be looked up with tsd_hash_search() by passing the * key you wish to lookup and DTOR_PID constant as the pid. * * The second type of entry is called a 'pid' entry and it is added to the * hash the first time a process set a key. The 'pid' entry is also used * as an anchor and all tsd for the process will be linked to it. This * list is using during tsd_exit() to ensure all registered destructors * are run for the process. The 'pid' entry may be looked up with * tsd_hash_search() by passing the PID_KEY constant as the key, and * the process pid.

I suspect you'll have bigger * problems than this implementation. * * It is also assumed that: * * 1) Chars have 8 bits. * 2) We can always do 32-bit-aligned int memory accesses and byte-aligned * memcpy, memset and memcmp. * 3) Arrays passed to xdr_array() are packed and the compiler/architecture * supports element-sized-aligned memory accesses. * 4) Negative integers are natively stored in two's complement binary * representation. * * No checks are done for the 4 assumptions above, though. * * === Caller expectations === * * Existing documentation does not describe the semantics of XDR operations very * well. Therefore, some assumptions about failure semantics will be made and * will be described below: * * 1) If any encoding operation fails (e.g., due to lack of buffer space), the * the stream should be considered valid only up to the encoding operation * previous to the one that first failed. However, the stream size as returned * by xdr_control() cannot be considered to be strictly correct (it may be * bigger). * * Putting it another way, if there is an encoding failure it's undefined * whether anything is added to the stream in that operation and therefore * neither xdr_control() nor future encoding operations on the same stream can * be relied upon to produce correct results. * * 2) If a decoding operation fails, it's undefined whether anything will be * decoded into passed buffers/pointers during that operation, or what the * values on those buffers will look like. * * Future decoding operations on the same stream will also have similar * undefined behavior. * * 3) When the first decoding operation fails it is OK to trust the results of * previous decoding operations on the same stream, as long as the caller * expects a failure to be possible (e.g. due to end-of-stream). * * However, this is highly discouraged because the caller should know the * stream size and should be coded to expect any decoding failure to be data * corruption due to hardware, accidental or even malicious causes, which should * be handled gracefully in all cases. * * In very rare situations where there are strong reasons to believe the data * can be trusted to be valid and non-tampered with, then the caller may assume * a decoding failure to be a bug (e.g. due to mismatched data types) and may * fail non-gracefully. * * 4) Non-zero padding bytes will cause the decoding operation to fail. * * 5) Zero bytes on string types will also cause the decoding operation to fail. * * 6) It is assumed that either the pointer to the stream buffer given by the * caller is 32-bit aligned or the architecture supports non-32-bit-aligned int * memory accesses. * * 7) The stream buffer and encoding/decoding buffers/ptrs should not overlap. * * 8) If a caller passes pointers to non-kernel memory (e.g., pointers to user * space or MMIO space), the computer may explode. */ static struct xdr_ops xdrmem_encode_ops;

It can also be used to run the full suite * of regression tests or particular tests. \*****************************************************************************/ #include #include #include #include #include #include #include #include #include #include #include "splat-internal.h" static struct list_head splat_module_list; static spinlock_t splat_module_lock; static int splat_open(struct inode *inode, struct file *file) { splat_info_t *info; info = (splat_info_t *)kmalloc(sizeof(*info), GFP_KERNEL); if (info == NULL) return -ENOMEM; mutex_init(&info->info_lock, SPLAT_NAME, MUTEX_DEFAULT, NULL); info->info_size = SPLAT_INFO_BUFFER_SIZE; info->info_buffer = (char *)vmalloc(SPLAT_INFO_BUFFER_SIZE); if (info->info_buffer == NULL) { kfree(info); return -ENOMEM; } memset(info->info_buffer, 0, info->info_size); info->info_head = info->info_buffer; file->private_data = (void *)info; splat_print(file, "%s\n", spl_version); return 0; } static int splat_release(struct inode *inode, struct file *file) { splat_info_t *info = (splat_info_t *)file->private_data; ASSERT(info); ASSERT(info->info_buffer); mutex_destroy(&info->info_lock); vfree(info->info_buffer); kfree(info); return 0; } static int splat_buffer_clear(struct file *file, splat_cfg_t *kcfg, unsigned long arg) { splat_info_t *info = (splat_info_t *)file->private_data; ASSERT(info); ASSERT(info->info_buffer); mutex_enter(&info->info_lock); memset(info->info_buffer, 0, info->info_size); info->info_head = info->info_buffer; mutex_exit(&info->info_lock); return 0; } static int splat_buffer_size(struct file *file, splat_cfg_t *kcfg, unsigned long arg) { splat_info_t *info = (splat_info_t *)file->private_data; char *buf; int min, size, rc = 0; ASSERT(info); ASSERT(info->info_buffer); mutex_enter(&info->info_lock); if (kcfg->cfg_arg1 > 0) { size = kcfg->cfg_arg1; buf = (char *)vmalloc(size); if (buf == NULL) { rc = -ENOMEM; goto out; } /* Zero fill and truncate contents when coping buffer */ min = ((size < info->info_size) ? size : info->info_size); memset(buf, 0, size); memcpy(buf, info->info_buffer, min); vfree(info->info_buffer); info->info_size = size; info->info_buffer = buf; info->info_head = info->info_buffer; } kcfg->cfg_rc1 = info->info_size; if (copy_to_user((struct splat_cfg_t __user *)arg, kcfg, sizeof(*kcfg))) rc = -EFAULT; out: mutex_exit(&info->info_lock); return rc; } static splat_subsystem_t * splat_subsystem_find(int id) { splat_subsystem_t *sub; spin_lock(&splat_module_lock); list_for_each_entry(sub, &splat_module_list, subsystem_list) { if (id == sub->desc.id) { spin_unlock(&splat_module_lock); return sub; } } spin_unlock(&splat_module_lock); return NULL; } static int splat_subsystem_count(splat_cfg_t *kcfg, unsigned long arg) { splat_subsystem_t *sub; int i = 0; spin_lock(&splat_module_lock); list_for_each_entry(sub, &splat_module_list, subsystem_list) i++; spin_unlock(&splat_module_lock); kcfg->cfg_rc1 = i; if (copy_to_user((struct splat_cfg_t __user *)arg, kcfg, sizeof(*kcfg))) return -EFAULT; return 0; } static int splat_subsystem_list(splat_cfg_t *kcfg, unsigned long arg) { splat_subsystem_t *sub; splat_cfg_t *tmp; int size, i = 0; /* Structure will be sized large enough for N subsystem entries * which is passed in by the caller.
