That pair of bytes (and their overlapping bits) can be * used for this "flip bit" operation (it's the first pair tried, * actually). * * A table defines overlapping pairs--the bytes involved and bits * within them--that can be used this way. The byte offset is * relative to a starting point within the name, which will be set * to affect the bytes at the end of the name. The function is * called with a "bitseq" value which indicates which bit flip is * desired, and this translates directly into selecting which entry * in the bit_to_flip[] table to apply. * * The function returns 1 if the operation was successful. It * returns 0 if the result produced a character that's not valid in * a name (either '/' or a '\0'). Finally, it returns -1 if the bit * sequence number is beyond what is supported for a name of this * length. * * Discussion * ---------- * (Also see the discussion above find_alternate(), below.) * * In order to make this function work for any length name, the * table is ordered by increasing byte offset, so that the earliest * entries can apply to the shortest strings. This way all names * are done consistently. * * When bit flips occur, they can convert printable characters * into non-printable ones. In an effort to reduce the impact of * this, the first bit flips are chosen to affect bytes the end of * the name (and furthermore, toward the low bits of a byte). Those * bytes are often non-printable anyway because of the way they are * initially selected by obfuscate_name()). This is accomplished, * using later table entries first. * * Each row in the table doubles the number of alternates that * can be generated. A two-byte name is limited to using only * the first row, so it's possible to generate two alternates * (the original name, plus the alternate produced by flipping * the one pair of bits). In a 5-byte name, the effect of the * first byte overlaps the last by 4 its, and there are 8 bits * to flip, allowing for 256 possible alternates. * * Short names (less than 5 bytes) are never even obfuscated, so for * such names the relatively small number of alternates should never * really be a problem. * * Long names (more than 6 bytes, say) are not likely to exhaust * the number of available alternates. In fact, the table could * probably have stopped at 8 entries, on the assumption that 256 * alternates should be enough for most any situation. The entries * beyond those are present mostly for demonstration of how it could * be populated with more entries, should it ever be necessary to do * so. */ static int flip_bit( size_t name_len, unsigned char *name, uint32_t bitseq) { int index; size_t offset; unsigned char *p0, *p1; unsigned char m0, m1; struct { int byte; /* Offset from start within name */ unsigned char bit; /* Bit within that byte */ } bit_to_flip[][2] = { /* Sorted by second entry's byte */ { { 0, 0 }, { 1, 7 } }, /* Each row defines a pair */ { { 1, 0 }, { 2, 7 } }, /* of bytes and a bit within */ { { 2, 0 }, { 3, 7 } }, /* each byte.

So for example: * seq = 0: selects no bits to flip * seq = 1: selects the 0th bit to flip * seq = 2: selects the 1st bit to flip * seq = 3: selects the 0th and 1st bit to flip * ... and so on. * * The flip_bit() function takes care of the details of the bit * flipping within the name.

If the result is not valid, it returns 0. * Returns -1 if the sequence number is beyond the the maximum for * names of the given length. * * * Discussion * ---------- * The number of alternates available for a given name is dependent * on its length. A "bit flip" involves inverting two bits in * a name--the two bits being selected such that their values * affect the name's hash value in the same way. Alternates are * thus generated by inverting the value of pairs of such * "overlapping" bits in the original name. Each byte after the * first in a name adds at least one bit of overlap to work with. * (See comments above flip_bit() for more discussion on this.) * * So the number of alternates is dependent on the number of such * overlapping bits in a name. If there are N bit overlaps, there * 2^N alternates for that hash value. * * Here are the number of overlapping bits available for generating * alternates for names of specific lengths: * 1 0 (must have 2 bytes to have any overlap) * 2 1 One bit overlaps--so 2 possible alternates * 3 2 Two bits overlap--so 4 possible alternates * 4 4 Three bits overlap, so 2^3 alternates * 5 8 8 bits overlap (due to wrapping), 256 alternates * 6 18 2^18 alternates * 7 28 2^28 alternates * ... * It's clear that the number of alternates grows very quickly with * the length of the name. But note that the set of alternates * includes invalid names. And for certain (contrived) names, the * number of valid names is a fairly small fraction of the total * number of alternates. * * The main driver for this infrastructure for coming up with * alternate names is really related to names 5 (or possibly 6) * bytes in length. 5-byte obfuscated names contain no randomly- * generated bytes in them, and the chance of an obfuscated name * matching an already-seen name is too high to just ignore. This * methodical selection of alternates ensures we don't produce * duplicate names unless we have exhausted our options. */ static int find_alternate( size_t name_len, unsigned char *name, uint32_t seq) { uint32_t bitseq = 0; uint32_t bits = seq; if (!seq) return 1; /* alternate 0 is the original name */ if (name_len < 2) /* Must have 2 bytes to flip */ return -1; for (bitseq = 0; bits; bitseq++) { uint32_t mask = 1 << bitseq; int fb; if (!(bits & mask)) continue; fb = flip_bit(name_len, name, bitseq); if (fb < 1) return fb ? -1 : 0; bits ^= mask; } return 1; } /* * Look up the given name in the name table.

We now also detect hfs+ filesystems. xfsprogs-2.5.2 (25 June 2003) - Fix xvm stripe detection in libdisk - pass correctly sized structures to xvm ioctls. - Add pthread library checks into configure and build scripts for work-in-progress on xfs_repair and xfs_copy. - Fix missing initialisation of stripe unit/width alignment information during libxfs_mount. - Fix botched repair typecast for multi-terabyte filesystems. xfsprogs-2.5.1 (23 June 2003) - Fix libdisk device driver (volume managers) detection code used by mkfs, so that drivers with multiple majors are not incorrectly processed. xfsprogs-2.5.0 (18 June 2003) - Fix libdisk (and hence mkfs) code which warns on MD devices with the clean flag not set, apparently this is not so wise. - Fix libxfs_device_zero to work with smaller-than-requested write return values. - Fix error in xfs_io pwrite code with large request sizes. - Fix rounding-down-input problems in several xfs_io commands. - Changed mkfs.xfs default log size scaling algorithm slightly, to create larger logs at smaller filesystem sizes by default (thanks to Andi Kleen for the patch). - Enable support for sector sizes larger than 512 bytes. xfsprogs-2.4.12 (02 June 2003) - Fix xfs_logprint handling of any version 2 log device. - Remove calls to exit in libhandle, propogate errors to caller, and bumped libhandle version from 1.0.1 to 1.0.2. xfsprogs-2.4.11 (30 May 2003) - Extract device sector size at mkfs time and issue warnings if the requested filesystem sector size is too small. - Sync up user/kernel source in libxfs, libxlog and headers. - Skip realtime initialisation in libxfs mount path if the caller is xfs_db, otherwise we get nonsense warnings. - Update xfs_io with a couple of additional commands. - Fix xfs_logprint handling of corrupt v2 log devices. xfsprogs-2.4.10 (12 May 2003) - Fix a bug in mkfs - creating version 2 logs, an incorrect stripe unit value was being passed to libxfs_clear_log. All recent versions of xfs_repair will fix this, however, because xfs_repair uses the correct stripe unit value. - Fix a bug in xfs_logprint, when dumping a corrupt log. - FreeBSD updates from Alexander Kabaev. - Large sector size updates for mkfs (disabled at the moment). - Large sector size fixes for xfs_repair. - Sync up with aeb's mount source for filesystem detection. xfsprogs-2.4.9 (03 May 2003) - Allow xfs_repair to run on read-only filesystems. xfsprogs-2.4.8 (26 April 2003) -

Implement get_unaligned/put_unaligned in libxfs. xfsprogs-2.4.4 (30 March 2003) - Correct display of imaxpct in mkfs.xfs output. - Portability changes; including some code to support use of several tools on Mac OS X (for Russell), ditto for FreeBSD (from Russell); also did a simplistic backport to IRIX (for me), so that I can run purify on some of the tools. - See doc/INSTALL for more details on this. - Sync up user/kernel source in libxfs and headers. - Fix up some warnings when compiling libxfs on big endian platforms. - Fix a configure.in botch which resulted in libreadline always being used even when it was not asked for. - Fixed the configure.in script so that if gettext disabled, we don't check for the gettext tools (and no longer fails if they were not found). - Added the ability to specify a different user and/or group to install as (previously, and still by default, root/root were always used here). xfsprogs-2.4.3 (27 March 2003) - Cleanups to the build process, in particular the automatic rpm package generation Makefile and spec file template. - Makepkgs script can now propagate failures back from make. - Minor configure.in update to deal with readline libraries which have not been linked correctly. xfsprogs-2.4.2 (25 March 2003) - Added the xfs_io(8) command, an xfs_db(8) alike command for testing and debugging the XFS file IO path. - Added an optional dependency on the GNU readline library which is "off" by default and enabled with the configure option --enable-readline=yes; it affects the interactive tools only (xfs_db and now xfs_io). -

Sync up user/kernel source in lib{xfs,xlog} and headers. - Fixed incorrect use of XFS_FSB_TO_DADDR macro in xfs_db's faddr.c::fa_dirblock routine - now use XFS_FSB_TO_BB here, as set_cur() takes basic blocks as its third parameter. - Fixed obscure issue in mkfs where only the first AG would get its AGFL freelist "fixed" - not clear this caused any issues in practice (on Linux it's always been this way, we now match up with IRIX though). - Made xfs_growfs filesystem geometry output match up with that displayed by mkfs.xfs (xfs_growfs was missing a comma before the log version field). - Fixed an issue in xfs_repair where data past the end of the valid superblock fields was sometimes not cleared, when it really should have been (due to a libxfs problem). - Shell scripts (xfs_info, xfs_check, etc) now also report the xfsprogs version number via -V, like other commands. xfsprogs-2.3.7 (14 November 2002) - Fix an endian bug in xfs_db freesp command when descending into multi-level agf cnt/bno btrees. xfsprogs-2.3.6 (31 October 2002) -

Fix size calculation bug in xfs_repair's memory allocation, reduces memory usage by a factor of 4. xfsprogs-2.3.3 (16 September 2002) - Fix mkfs bug when optimizing AG size on striped devices, ASSERT(agcount != 0) tripped on single-ag filesystems. xfsprogs-2.3.2 (10 September 2002) -

Sync user/kernel headers (arch.h incorporated into xfs_arch.h, and several other minor changes). xfsprogs-2.1.2 (17 July 2002) - Fix up log stripe unit specification options, and update man page. Also fix suffix handling for data su/sw options (disallow unit suffixes on -d sunit,swidth,sw and -l sunit).

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 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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! ---------------------------------------------------------------------- GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 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.

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. ---------------------------------------------------------------------- GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 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.

See the README file in the top level directory for details about how to contribute to the XFS project. Linux Instructions ================== 0. If you have the binary rpm, simply install it and skip to step 2 (below). The rpm command to do this is: # rpm -Uvh xfsprogs-*.rpm [and optionally, for the development libraries and headers] # rpm -Uvh xfsprogs-devel-*.rpm The Debian command to do this is: # apt-get install xfsprogs [and optionally, for the development libraries and headers] # apt-get install xfslibs-dev 1. Configure, build and install the package The xfsprogs package uses autoconf/configure and expects a GNU build environment (your platform must at least have both autoconf and gmake). You will also need to have installed either the e2fsprogs-devel package (on an RPM based system) or the uuid-dev package (on a Debian system) as some of the commands make use of the UUID library provided by these. To build the package and install it manually, use the following steps: # make # su root # make install [and optionally, for the development libraries and headers] # make install-dev Note that there are so many "install" variants out there that we wrote our own script (see "install-sh" in the top level directory). If you wish to turn off debugging asserts in the command build and turn on the optimizer then set the shell environment variables: OPTIMIZER=-O1 DEBUG=-DNDEBUG before running make or Makepkgs. Mac OS X Instructions ===================== 0. Note: since there is no XFS implementation on Mac OS X, you are severely limited in what you can do. mkfs.xfs(8), xfs_db(8) and xfs_repair(8) are the only functional tools on this platform, as they do not interact with the XFS kernel code at all. Still, it can be useful to have access to these utilities from Mac OS X in a dual boot configuration, for example. However, keep on mind that mkfs.xfs on Mac OS X has disabled device access, although you can create a filesystem in a file. Also note that existing filesystem detection is disabled. 1. Configure, build and install the package The xfsprogs package uses autoconf/configure and expects a GNU build environment (your platform must at least have both autoconf, make, and glibtool). You will also need to have built and installed the UUID library which is provided by the e2fsprogs source package. (Or use Homebrew, Macports or any other 3rd party package manager.) Building libuuid: [download; unzip/untar e2fsprogs; cd e2fsprogs] $ ./configure --prefix=/usr --mandir=/usr/share/man $ make lib/ext2fs/ext2_types.h $ cd lib/uuid $ make $ su root # make install [verify that you now have a /usr/lib/libuuid.a] Building xfsprogs: [firstly set these environment variables to these values] TAR=/usr/bin/gnutar LIBTOOL=/usr/bin/glibtool INSTALL_GROUP=wheel LOCAL_CONFIGURE_OPTIONS="--enable-gettext=no --enable-blkid=no" $ make $ su root # make install [and optionally, for the development libraries and headers] # make install-dev IRIX Instructions ================= 0. Note: building this package on IRIX is mainly useful for the XFS developers who want to run purify on some of the tools. Most tools are not functional due to incomplete support for the syssgi and fcntl interfaces that XFS provides and which these tools make extensive use of. 1. Configure, build and install the package The xfsprogs package uses autoconf/configure and expects a GNU build environment which can be obtained by installing a number of freeware packages (gcc, autoconf, libtool, gmake). Even though IRIX provides a set of UUID functions via libc, you still need to have built and installed the UUID library which is provided by the e2fsprogs source package. This is because some difficult to resolve differences exist between the UUID functions and data types, which makes co-existence of these more trouble than its worth at the moment. Follow the instructions above for building and installing libuuid.

First you need to install sparse, either from your distribution or from source as provided at http://www.kernel.org/pub/software/devel/sparse/. To simply build the xfsprogs source code while checking the source using sparse just set the compiler to cgcc, which is a wrapper that calls both sparse and gcc using: CC=cgcc ./configure Now that default warnings from sparse are a little bit verbose checking for various not that important things and also complaining about the glibc system headers. It does however not check for bitwise annotation which are very important for xfsprogs to verify the endianess handling of the on-disk structures is correct. To get a more reasonable set of warnings build xfsprogs using: LCFLAGS="-Wbitwise -Wno-transparent-union -Wno-old-initializer -Wno-decl" make You are of course free to experiment with the warnings flags documented in the sparse manpage to check xfsprogs for other issues. xfsprogs-4.3.0+nmu1ubuntu1.1/estimate/0000775000000000000000000000000012625722130014433 5ustar xfsprogs-4.3.0+nmu1ubuntu1.1/estimate/Makefile0000664000000000000000000000055112560572026016101 0ustar # # Copyright (c) 2000-2001 Silicon Graphics, Inc.

They are intended for use by a limited set of system utilities such as backup programs. They are supported only by the XFS filesystem. Link with the .B libhandle library to access these functions. .PP A handle, .IR hanp , uniquely identifies a filesystem object or an entire filesystem. There is one and only one handle per filesystem or filesystem object. Handles consist of some number of bytes. The size of a handle (i.e. the number of bytes comprising it) varies by the type of handle and may vary for different objects of the same type. The content of a handle is opaque to applications. Since handle sizes vary and their contents are opaque, handles are described by two quantities, a pointer .RI ( hanp ") and a size (" hlen ). The size, .IR hlen , indicates the number of bytes in the handle which are pointed to by the pointer. .PP The .BR path_to_handle () function returns the handle for the object given by the .I path argument. If the final component of the path name is a symbolic link, the handle returned is that of the link itself. .PP The .BR path_to_fshandle () function returns the handle for the filesystem in which the object given by the .I path argument resides. .PP The .BR fd_to_handle () function returns the handle for the object referenced by the .I fd argument, which must be a valid file descriptor. .PP The .BR handle_to_fshandle () function returns the handle for the filesystem in which the object referenced by the handle given by the .I hanp and .I hlen arguments resides. .PP The .BR open_by_handle () function opens a file descriptor for the object referenced by a handle. It is analogous and identical to .BR open (2) with the exception of accepting handles instead of path names. .PP The .BR readlink_by_handle () function returns the contents of a symbolic link referenced by a handle. .PP The .BR attr_multi_by_handle () function manipulates multiple user attributes on a filesystem object. It is analogous and identical to .BR attr_multif (3) except that a handle is specified instead of a file descriptor. .PP The .BR attr_list_by_handle () function returns the names of the user attributes of a filesystem object. It is analogous and identical to .BR attr_listf (3) except that a handle is specified instead of a file descriptor. .PP The .BR fssetdm_by_handle () function sets the .B di_dmevmask and .B di_dmstate fields in an XFS on-disk inode. It is analogous to the .BR "XFS_IOC_FSSETDM xfsctl" (3) command, except that a handle is specified instead of a file. .PP The .BR free_handle () function frees the storage allocated for handles returned by the following functions: .BR path_to_handle (), .BR path_to_fshandle (), .BR fd_to_handle (), and .BR handle_to_fshandle (). .PP The .BR getparents_by_handle () function returns an array of .B parent_t structures for each hardlink to the inode represented by the given handle. The parent structure encodes the parent inode number, generation number and the basename of the link. .B This function is not operational on Linux. .PP The .BR getparentpaths_by_handle () function is identical to the .BR getparents_by_handle () function except that instead of returning the basename it returns the path of the link up to the mount point. .B This function is also not operational on Linux. .SH RETURN VALUE The function .BR free_handle () has no failure indication. The other functions return the value 0 to the calling process if they succeed; otherwise, they return the value \-1 and set .I errno to indicate the error. .SH ERRORS .TP .B EACCES Search permission was denied for a component of .IR path . .TP .B EBADF .I fd is not a valid and open file descriptor. .TP .B EFAULT An argument pointed to an invalid address. .TP .B EINVAL .I path is in a filesystem that does not support these functions. .TP .B ELOOP Too many symbolic links were encountered in translating the path name. .TP .B ENAMETOOLONG A component of .I path or the entire length of .I path exceeds filesystem limits. .TP .B ENOENT A component of .I path does not exist. .TP .B EPERM The caller does not have sufficient privileges. .SH SEE ALSO .BR open (2), .BR readlink (2), .BR attr_multi (3), .BR attr_list (3), .BR xfsctl (3), .BR xfs (5). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man3/xfsctl.30000664000000000000000000004640212560572026015633 0ustar .TH XFSCTL 3 .SH NAME xfsctl \- control XFS filesystems and individual files .SH C SYNOPSIS .B #include .HP .BI "int\ xfsctl(const char *" path ", int " fd ", int " cmd ", void *" ptr ); .PP .BI "int platform_test_xfs_fd(int " fd ); .br .BI "int platform_test_xfs_path(const char *" path ); .SH DESCRIPTION Some functionality specific to the XFS filesystem is accessible to applications through platform-specific system call interfaces. These operations can be divided into two sections \- operations that operate on individual files, and operations that operate on the filesystem itself. Care should be taken when issuing .BR xfsctl () calls to ensure the target path and file descriptor (both must be supplied) do indeed represent a file from an XFS filesystem. The .BR statfs (2) and .BR fstatfs (2) system calls can be used to determine whether or not an arbitrary path or file descriptor belong to an XFS filesystem. These are not portable however, so the routines .BR platform_test_xfs_fd () and .BR platform_test_xfs_path () provide a platform-independent mechanism. .SS File Operations In order to effect an operation on an individual file, the pathname and descriptor arguments passed to .B xfsctl identifies the file being operated on. The final argument described below refers to the final argument of .BR xfsctl . All of the data structures and macros mentioned below are defined in the .RI < xfs/xfs_fs.h > header file. .PP .B XFS_IOC_ALLOCSP .br .B XFS_IOC_ALLOCSP64 .br .B XFS_IOC_FREESP .PD 0 .TP .B XFS_IOC_FREESP64 Alter storage space associated with a section of the ordinary file specified. The section is specified by a variable of type .BR xfs_flock64_t , pointed to by the final argument. The data type .B xfs_flock64_t contains the following members: .B l_whence is 0, 1, or 2 to indicate that the relative offset .B l_start will be measured from the start of the file, the current position, or the end of the file, respectively (i.e., .B l_start is the offset from the position specified in .BR l_whence ). If the offset specified is before the current end of file, any data previously written into this section is no longer accessible. If the offset specified is beyond the current end of file, the file is grown and filled with zeroes. The .B l_len field is currently ignored, and should be set to zero. .BR XFS_IOC_ALLOCSP , .BR XFS_IOC_ALLOCSP64 , .B XFS_IOC_FREESP and .B XFS_IOC_FREESP64 operations are all identical. .TP .B XFS_IOC_FSSETDM Set the di_dmevmask and di_dmstate fields in an XFS on-disk inode. The only legitimate values for these fields are those previously returned in the .B bs_dmevmask and .B bs_dmstate fields of the bulkstat structure. The data referred to by the final argument is a .BR "struct fsdmidata" . This structure's members are .B fsd_dmevmask and .BR fsd_dmstate . The di_dmevmask field is set to the value in .BR fsd_dmevmask . The di_dmstate field is set to the value in .BR fsd_dmstate . This command is restricted to root or to processes with device management capabilities. Its sole purpose is to allow backup and restore programs to restore the aforementioned critical on-disk inode fields. .TP .B XFS_IOC_DIOINFO Get information required to perform direct I/O on the specified file descriptor. Direct I/O is performed directly to and from a user's data buffer. Since the kernel's buffer cache is no longer between the two, the user's data buffer must conform to the same type of constraints as required for accessing a raw disk partition. The final argument points to a variable of type .BR "struct dioattr" , which contains the following members: .B d_mem is the memory alignment requirement of the user's data buffer. .B d_miniosz specifies block size, minimum I/O request size, and I/O alignment. The size of all I/O requests must be a multiple of this amount and the value of the seek pointer at the time of the I/O request must also be an integer multiple of this amount. .B d_maxiosz is the maximum I/O request size which can be performed on the file descriptor. If an I/O request does not meet these constraints, the .BR read (2) or .BR write (2) will fail with EINVAL. All I/O requests are kept consistent with any data brought into the cache with an access through a non-direct I/O file descriptor. .TP .B XFS_IOC_FSGETXATTR Get additional attributes associated with files in XFS file systems. The final argument points to a variable of type .BR "struct fsxattr" , whose fields include: .B fsx_xflags (extended flag bits), .B fsx_extsize (nominal extent size in file system blocks), .B fsx_nextents (number of data extents in the file). A .B fsx_extsize value returned indicates that a preferred extent size was previously set on the file, a .B fsx_extsize of zero indicates that the defaults for that filesystem will be used. Currently the meaningful bits for the .B fsx_xflags field are: .PD 0 .RS .TP 1.0i .SM "Bit 0 (0x1) \- XFS_XFLAG_REALTIME" The file is a realtime file. .TP .SM "Bit 1 (0x2) \- XFS_XFLAG_PREALLOC" The file has preallocated space. .TP .SM "Bit 3 (0x8) \- XFS_XFLAG_IMMUTABLE" The file is immutable - it cannot be modified, deleted or renamed, no link can be created to this file and no data can be written to the file. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this flag. .TP .SM "Bit 4 (0x10) \- XFS_XFLAG_APPEND" The file is append-only - it can only be open in append mode for writing. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this flag. .TP .SM "Bit 5 (0x20) \- XFS_XFLAG_SYNC" All writes to the file are synchronous. .TP .SM "Bit 6 (0x40) \- XFS_XFLAG_NOATIME" When the file is accessed, its atime record is not modified. .TP .SM "Bit 7 (0x80) \- XFS_XFLAG_NODUMP" The file should be skipped by backup utilities. .TP .SM "Bit 8 (0x100) \- XFS_XFLAG_RTINHERIT" Realtime inheritance bit - new files created in the directory will be automatically realtime, and new directories created in the directory will inherit the inheritance bit. .TP .SM "Bit 9 (0x200) \- XFS_XFLAG_PROJINHERIT" Project inheritance bit - new files and directories created in the directory will inherit the parents project ID. New directories also inherit the project inheritance bit. .TP .SM "Bit 10 (0x400) \- XFS_XFLAG_NOSYMLINKS" Can only be set on a directory and disallows creation of symbolic links in that directory. .TP .SM "Bit 11 (0x800) \- XFS_XFLAG_EXTSIZE" Extent size bit - if a basic extent size value is set on the file then the allocator will allocate in multiples of the set size for this file (see .B XFS_IOC_FSSETXATTR below). .TP .SM "Bit 12 (0x1000) \- XFS_XFLAG_EXTSZINHERIT" Extent size inheritance bit - new files and directories created in the directory will inherit the parents basic extent size value (see .B XFS_IOC_FSSETXATTR below). Can only be set on a directory. .TP .SM "Bit 13 (0x2000) \- XFS_XFLAG_NODEFRAG" No defragment file bit - the file should be skipped during a defragmentation operation. When applied to a directory, new files and directories created will inherit the no\-defrag bit. .TP .SM "Bit 14 (0x4000) \- XFS_XFLAG_FILESTREAM" Filestream allocator bit - allows a directory to reserve an allocation group for exclusive use by files created within that directory. Files being written in other directories will not use the same allocation group and so files within different directories will not interleave extents on disk. The reservation is only active while files are being created and written into the directory. .TP .SM "Bit 31 (0x80000000) \- XFS_XFLAG_HASATTR" The file has extended attributes associated with it. .RE .PP .PD .TP .B XFS_IOC_FSGETXATTRA Identical to .B XFS_IOC_FSGETXATTR except that the .B fsx_nextents field contains the number of attribute extents in the file. .TP .B XFS_IOC_FSSETXATTR Set additional attributes associated with files in XFS file systems. The final argument points to a variable of type .BR "struct fsxattr" , but only the following fields are used in this call: .BR fsx_xflags , .B fsx_extsize and .BR fsx_projid . The .B fsx_xflags realtime file bit and the file's extent size may be changed only when the file is empty, except in the case of a directory where the extent size can be set at any time (this value is only used for regular file allocations, so should only be set on a directory in conjunction with the XFS_XFLAG_EXTSZINHERIT flag). .TP .B XFS_IOC_GETBMAP Get the block map for a segment of a file in an XFS file system. The final argument points to an arry of variables of type .BR "struct getbmap" . All sizes and offsets in the structure are in units of 512 bytes. The structure fields include: .B bmv_offset (file offset of segment), .B bmv_block (starting block of segment), .B bmv_length (length of segment), .B bmv_count (number of array entries, including the first), and .B bmv_entries (number of entries filled in). The first structure in the array is a header, and the remaining structures in the array contain block map information on return. The header controls iterative calls to the .B XFS_IOC_GETBMAP command. The caller fills in the .B bmv_offset and .B bmv_length fields of the header to indicate the area of interest in the file, and fills in the .B bmv_count field to indicate the length of the array. If the .B bmv_length value is set to \-1 then the length of the interesting area is the rest of the file. On return from a call, the header is updated so that the command can be reused to obtain more information, without re-initializing the structures. Also on return, the .B bmv_entries field of the header is set to the number of array entries actually filled in. The non-header structures will be filled in with .BR bmv_offset , .BR bmv_block , and .BR bmv_length . If a region of the file has no blocks (is a hole in the file) then the .B bmv_block field is set to \-1. .TP .B XFS_IOC_GETBMAPA Identical to .B XFS_IOC_GETBMAP except that information about the attribute fork of the file is returned. .PP .B XFS_IOC_RESVSP .TP .B XFS_IOC_RESVSP64 This command is used to allocate space to a file. A range of bytes is specified using a pointer to a variable of type .B xfs_flock64_t in the final argument. The blocks are allocated, but not zeroed, and the file size does not change. If the XFS filesystem is configured to flag unwritten file extents, performance will be negatively affected when writing to preallocated space, since extra filesystem transactions are required to convert extent flags on the range of the file written. If .BR xfs_info (8) reports unwritten=1, then the filesystem was made to flag unwritten extents. .PP .B XFS_IOC_UNRESVSP .TP .B XFS_IOC_UNRESVSP64 This command is used to free space from a file. A range of bytes is specified using a pointer to a variable of type .B xfs_flock64_t in the final argument. Partial filesystem blocks are zeroed, and whole filesystem blocks are removed from the file. The file size does not change. .TP .B XFS_IOC_ZERO_RANGE This command is used to convert a range of a file to zeros without issuing data IO. A range of bytes is specified using a pointer to a variable of type .B xfs_flock64_t in the final argument. Blocks are preallocated for regions that span holes in the file, and the entire range is converted to unwritten extents. This operation is a fast method of overwriting any from the range specified with zeros without removing any blocks or having to write zeros to disk. Any subsequent read in the given range will return zeros until new data is written. This functionality requires filesystems to support unwritten extents. If .BR xfs_info (8) reports unwritten=1, then the filesystem was made to flag unwritten extents. .\" .TP .\" .B XFS_IOC_GETBIOSIZE .\" This command gets information about the preferred buffered I/O .\" size used by the system when performing buffered I/O (e.g. .\" standard Unix non-direct I/O) to and from the file. .\" The information is passed back in a structure of type .\" .B "struct biosize" .\" pointed to by the final argument. .\" biosize lengths are expressed in log base 2. .\" That is if the value is 14, then the true size is 2^14 (2 raised to .\" the 14th power). .\" The .\" .B biosz_read .\" field will contain the current value used by the system when reading .\" from the file. .\" Except at the end-of-file, the system will read from the file in .\" multiples of this length. .\" The .\" .B biosz_write .\" field will contain the current value used by the system when writing .\" to the file. .\" Except at the end-of-file, the system will write to the file in .\" multiples of this length. .\" The .\" .B dfl_biosz_read .\" and .\" .B dfl_biosz_write .\" will be set to the system default values for the opened file. .\" The .\" .B biosz_flags .\" field will be set to 1 if the current read or write value has been .\" explicitly set. .\" .\" .TP .\" .B XFS_IOC_SETBIOSIZE .\" This command sets information about the preferred buffered I/O size .\" used by the system when performing buffered I/O (e.g. standard Unix .\" non-direct I/O) to and from the file. .\" The information is passed in a structure of type .\" .B "struct biosize" .\" pointed to by the final argument. .\" Using smaller preferred I/O sizes can result in performance .\" improvements if the file is typically accessed using small .\" synchronous I/Os or if only a small amount of the file is accessed .\" using small random I/Os, resulting in little or no use of the .\" additional data read in near the random I/Os. .\" .\" To explicitly set the preferred I/O sizes, the .\" .B biosz_flags .\" field should be set to zero and the .\" .B biosz_read .\" and .\" .B biosz_write .\" fields should be set to the log base 2 of the desired read and .\" write lengths, respectively (e.g. 13 for 8K bytes, 14 for 16K .\" bytes, 15 for 32K bytes, etc.). Valid values are 13-16 .\" inclusive for machines with a 4K byte pagesize and 14-16 for .\" machines with a 16K byte pagesize. The specified read and .\" write values must also result in lengths that are greater than .\" or equal to the filesystem block size. .\" The .\" .B dfl_biosz_read .\" and .\" .B dfl_biosz_write .\" fields are ignored. .\" .\" If biosizes have already been explicitly set due to a prior use .\" of .\" .BR XFS_IOC_SETBIOSIZE , .\" and the requested sizes are larger than the .\" existing sizes, the .\" .I xfsctl .\" call will return successfully and the .\" system will use the smaller of the two sizes.

They are all subject to change and should not be called directly by applications. .SS Filesystem Operations In order to effect one of the following operations, the pathname and descriptor arguments passed to .BR xfsctl () can be any open file in the XFS filesystem in question. .PP .TP .B XFS_IOC_FSINUMBERS This interface is used to extract a list of valid inode numbers from an XFS filesystem. It is intended to be called iteratively, to obtain the entire set of inodes. The information is passed in and out via a structure of type .B xfs_fsop_bulkreq_t pointed to by the final argument. .B lastip is a pointer to a variable containing the last inode number returned, initially it should be zero. .B icount is the size of the array of structures specified by .BR ubuffer . .B ubuffer is the address of an array of structures, of type .BR xfs_inogrp_t . This structure has the following elements: .B xi_startino (starting inode number), .B xi_alloccount (count of bits set in xi_allocmask), and .B xi_allocmask (mask of allocated inodes in this group). The bitmask is 64 bits long, and the least significant bit corresponds to inode .B xi_startino. Each bit is set if the corresponding inode is in use. .B ocount is a pointer to a count of returned values, filled in by the call. An output .B ocount value of zero means that the inode table has been exhausted. .TP .B XFS_IOC_FSBULKSTAT This interface is used to extract inode information (stat information) "in bulk" from a filesystem. It is intended to be called iteratively, to obtain information about the entire set of inodes in a filesystem. The information is passed in and out via a structure of type .B xfs_fsop_bulkreq_t pointed to by the final argument. .B lastip is a pointer to a variable containing the last inode number returned, initially it should be zero. .B icount indicates the size of the array of structures specified by .B ubuffer. .B ubuffer is the address of an array of structures of type .BR xfs_bstat_t . Many of the elements in the structure are the same as for the stat structure. The structure has the following elements: .B bs_ino (inode number), .B bs_mode (type and mode), .B bs_nlink (number of links), .B bs_uid (user id), .B bs_gid (group id), .B bs_rdev (device value), .B bs_blksize (block size of the filesystem), .B bs_size (file size in bytes), .B bs_atime (access time), .B bs_mtime (modify time), .B bs_ctime (inode change time), .B bs_blocks (number of blocks used by the file), .B bs_xflags (extended flags), .B bs_extsize (extent size), .B bs_extents (number of extents), .B bs_gen (generation count), .B bs_projid_lo (project id - low word), .B bs_projid_hi (project id - high word, used when projid32bit feature is enabled), .B bs_dmevmask (DMIG event mask), .B bs_dmstate (DMIG state information), and .B bs_aextents (attribute extent count). .B ocount is a pointer to a count of returned values, filled in by the call. An output .B ocount value of zero means that the inode table has been exhausted. .TP .B XFS_IOC_FSBULKSTAT_SINGLE This interface is a variant of the .B XFS_IOC_FSBULKSTAT interface, used to obtain information about a single inode. for an open file in the filesystem of interest.

An XFS filesystem has up to three parts: a data section, a log section, and a realtime section. Using the default .BR mkfs.xfs (8) options, the realtime section is absent, and the log area is contained within the data section. The log section can be either separate from the data section or contained within it. The filesystem sections are divided into a certain number of .IR blocks , whose size is specified at .BR mkfs.xfs (8) time with the .B \-b option. .PP The data section contains all the filesystem metadata (inodes, directories, indirect blocks) as well as the user file data for ordinary (non-realtime) files and the log area if the log is .I internal to the data section. The data section is divided into a number of .IR "allocation groups" . The number and size of the allocation groups are chosen by .BR mkfs.xfs (8) so that there is normally a small number of equal-sized groups. The number of allocation groups controls the amount of parallelism available in file and block allocation. It should be increased from the default if there is sufficient memory and a lot of allocation activity. The number of allocation groups should not be set very high, since this can cause large amounts of CPU time to be used by the filesystem, especially when the filesystem is nearly full. More allocation groups are added (of the original size) when .BR xfs_growfs (8) is run. .PP The log section (or area, if it is internal to the data section) is used to store changes to filesystem metadata while the filesystem is running until those changes are made to the data section. It is written sequentially during normal operation and read only during mount. When mounting a filesystem after a crash, the log is read to complete operations that were in progress at the time of the crash. .PP The realtime section is used to store the data of realtime files. These files had an attribute bit set through .BR xfsctl (3) after file creation, before any data was written to the file. The realtime section is divided into a number of .I extents of fixed size (specified at .BR mkfs.xfs (8) time). Each file in the realtime section has an extent size that is a multiple of the realtime section extent size. .PP Each allocation group contains several data structures. The first sector contains the superblock. For allocation groups after the first, the superblock is just a copy and is not updated after .BR mkfs.xfs (8). The next three sectors contain information for block and inode allocation within the allocation group. Also contained within each allocation group are data structures to locate free blocks and inodes; these are located through the header structures. .PP Each XFS filesystem is labeled with a Universal Unique Identifier (UUID). The UUID is stored in every allocation group header and is used to help distinguish one XFS filesystem from another, therefore you should avoid using .BR dd (1) or other block-by-block copying programs to copy XFS filesystems. If two XFS filesystems on the same machine have the same UUID, .BR xfsdump (8) may become confused when doing incremental and resumed dumps. .BR xfsdump (8) and .BR xfsrestore (8) are recommended for making copies of XFS filesystems. .SH OPERATIONS Some functionality specific to the XFS filesystem is accessible to applications through the .BR xfsctl (3) and by-handle (see .BR open_by_handle (3)) interfaces. .SH MOUNT OPTIONS The following XFS-specific mount options may be used when mounting an XFS filesystem. Other generic options may be used as well; refer to the .BR mount (8) manual page for more details. .TP .B allocsize=size Sets the buffered I/O end-of-file preallocation size when doing delayed allocation writeout. Valid values for this option are page size (typically 4KiB) through to 1GiB, inclusive, in power-of-2 increments. .sp The default behavior is for dynamic end-of-file preallocation size, which uses a set of heuristics to optimise the preallocation size based on the current allocation patterns within the file and the access patterns to the file. Specifying a fixed allocsize value turns off the dynamic behavior. .TP .BR attr2 | noattr2 The options enable/disable an "opportunistic" improvement to be made in the way inline extended attributes are stored on-disk. When the new form is used for the first time when attr2 is selected (either when setting or removing extended attributes) the on-disk superblock feature bit field will be updated to reflect this format being in use. .sp The default behavior is determined by the on-disk feature bit indicating that attr2 behavior is active. If either mount option it set, then that becomes the new default used by the filesystem. .sp CRC enabled filesystems always use the attr2 format, and so will reject the noattr2 mount option if it is set. .TP .BR barrier | nobarrier Enables/disables the use of block layer write barriers for writes into the journal and for data integrity operations. This allows for drive level write caching to be enabled, for devices that support write barriers. .sp Barriers are enabled by default. .TP .BR discard | nodiscard Enable/disable the issuing of commands to let the block device reclaim space freed by the filesystem. This is useful for SSD devices, thinly provisioned LUNs and virtual machine images, but may have a performance impact. .sp Note: It is currently recommended that you use the fstrim application to discard unused blocks rather than the discard mount option because the performance impact of this option is quite severe. For this reason, nodiscard is the default. .TP .BR grpid | bsdgroups | nogrpid | sysvgroups These options define what group ID a newly created file gets. When grpid is set, it takes the group ID of the directory in which it is created; otherwise it takes the fsgid of the current process, unless the directory has the setgid bit set, in which case it takes the gid from the parent directory, and also gets the setgid bit set if it is a directory itself. .TP .B filestreams Make the data allocator use the filestreams allocation mode across the entire filesystem rather than just on directories configured to use it. .TP .BR ikeep | noikeep When ikeep is specified, XFS does not delete empty inode clusters and keeps them around on disk. When noikeep is specified, empty inode clusters are returned to the free space pool. noikeep is the default. .TP .BR inode32 | inode64 When inode32 is specified, it indicates that XFS limits inode creation to locations which will not result in inode numbers with more than 32 bits of significance. .sp When inode64 is specified, it indicates that XFS is allowed to create inodes at any location in the filesystem, including those which will result in inode numbers occupying more than 32 bits of significance. .sp inode32 is provided for backwards compatibility with older systems and applications, since 64 bits inode numbers might cause problems for some applications that cannot handle large inode numbers. If applications are in use which do not handle inode numbers bigger than 32 bits, the inode32 option should be specified. .sp For kernel v3.7 and later, inode64 is the default. .TP .BR largeio | nolargeio If "nolargeio" is specified, the optimal I/O reported in st_blksize by stat(2) will be as small as possible to allow user applications to avoid inefficient read/modify/write I/O. This is typically the page size of the machine, as this is the granularity of the page cache. .sp If "largeio" specified, a filesystem that was created with a "swidth" specified will return the "swidth" value (in bytes) in st_blksize. If the filesystem does not have a "swidth" specified but does specify an "allocsize" then "allocsize" (in bytes) will be returned instead. Otherwise the behavior is the same as if "nolargeio" was specified. nolargeio is the default. .TP .B logbufs=value Set the number of in-memory log buffers. Valid numbers range from 2\(en8 inclusive. .sp The default value is 8 buffers. .sp If the memory cost of 8 log buffers is too high on small systems, then it may be reduced at some cost to performance on metadata intensive workloads. The logbsize option below controls the size of each buffer and so is also relevant to this case. .TP .B logbsize=value Set the size of each in-memory log buffer. The size may be specified in bytes, or in kibibytes (KiB) with a "k" suffix. Valid sizes for version 1 and version 2 logs are 16384 (value=16k) and 32768 (value=32k). Valid sizes for version 2 logs also include 65536 (value=64k), 131072 (value=128k) and 262144 (value=256k). The logbsize must be an integer multiple of the log stripe unit configured at mkfs time. .sp The default value for version 1 logs is 32768, while the default value for version 2 logs is MAX(32768, log_sunit). .TP .BR logdev=device " and " rtdev=device Use an external log (metadata journal) and/or real-time device. An XFS filesystem has up to three parts: a data section, a log section, and a real-time section. The real-time section is optional, and the log section can be separate from the data section or contained within it. .TP .B noalign Data allocations will not be aligned at stripe unit boundaries. This is only relevant to filesystems created with non-zero data alignment parameters (sunit, swidth) by mkfs. .TP .B norecovery The filesystem will be mounted without running log recovery. If the filesystem was not cleanly unmounted, it is likely to be inconsistent when mounted in "norecovery" mode. Some files or directories may not be accessible because of this. Filesystems mounted "norecovery" must be mounted read-only or the mount will fail. .TP .B nouuid Don't check for double mounted file systems using the file system uuid. This is useful to mount LVM snapshot volumes, and often used in combination with "norecovery" for mounting read-only snapshots. .TP .B noquota Forcibly turns off all quota accounting and enforcement within the filesystem. .TP .B uquota/usrquota/quota/uqnoenforce/qnoenforce User disk quota accounting enabled, and limits (optionally) enforced. Refer to xfs_quota(8) for further details. .TP .B gquota/grpquota/gqnoenforce Group disk quota accounting enabled and limits (optionally) enforced. Refer to xfs_quota(8) for further details. .TP .B pquota/prjquota/pqnoenforce Project disk quota accounting enabled and limits (optionally) enforced. Refer to xfs_quota(8) for further details. .TP .BR sunit=value " and " swidth=value Used to specify the stripe unit and width for a RAID device or a stripe volume. "value" must be specified in 512-byte block units. These options are only relevant to filesystems that were created with non-zero data alignment parameters. .sp The sunit and swidth parameters specified must be compatible with the existing filesystem alignment characteristics. In general, that means the only valid changes to sunit are increasing it by a power-of-2 multiple. Valid swidth values are any integer multiple of a valid sunit value. .sp Typically the only time these mount options are necessary if after an underlying RAID device has had it's geometry modified, such as adding a new disk to a RAID5 lun and reshaping it. .TP .B swalloc Data allocations will be rounded up to stripe width boundaries when the current end of file is being extended and the file size is larger than the stripe width size. .TP .B wsync When specified, all filesystem namespace operations are executed synchronously. This ensures that when the namespace operation (create, unlink, etc) completes, the change to the namespace is on stable storage. This is useful in HA setups where failover must not result in clients seeing inconsistent namespace presentation during or after a failover event. .SH FILE ATTRIBUTES The XFS filesystem supports setting the following file attributes on Linux systems using the .BR chattr (1) utility: .sp .BR a " - append only" .sp .BR A " - no atime updates" .sp .BR d " - no dump" .sp .BR i " - immutable" .sp .BR S " - synchronous updates" .sp For descriptions of these attribute flags, please refer to the .BR chattr (1) man page. .SH SEE ALSO .BR chattr (1), .BR xfsctl (3), .BR mount (8), .BR mkfs.xfs (8), .BR xfs_info (8), .BR xfs_admin (8), .BR xfsdump (8), .BR xfsrestore (8). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/0000775000000000000000000000000012625722130014236 5ustar xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/Makefile0000664000000000000000000000060312560572026015702 0ustar # # Copyright (c) 2000-2001 Silicon Graphics, Inc.

XFS is a journaling filesystem and performs recovery at .BR mount (8) time if necessary, so .B fsck.xfs simply exits with a zero exit status. .PP If you wish to check the consistency of an XFS filesystem, or repair a damaged or corrupt XFS filesystem, see .BR xfs_repair (8). . .SH FILES .IR /etc/fstab . .SH SEE ALSO .BR fsck (8), .BR fstab (5), .BR xfs (5), .BR xfs_repair (8). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/mkfs.xfs.80000664000000000000000000006175412625713771016116 0ustar .TH mkfs.xfs 8 .SH NAME mkfs.xfs \- construct an XFS filesystem .SH SYNOPSIS .B mkfs.xfs [ .B \-b .I block_size ] [ .B \-m .I global_metadata_options ] [ .B \-d .I data_section_options ] [ .B \-f ] [ .B \-i .I inode_options ] [ .B \-l .I log_section_options ] [ .B \-n .I naming_options ] [ .B \-p .I protofile ] [ .B \-q ] [ .B \-r .I realtime_section_options ] [ .B \-s .I sector_size ] [ .B \-L .I label ] [ .B \-N ] [ .B \-K ] .I device .br .B mkfs.xfs \-V .SH DESCRIPTION .B mkfs.xfs constructs an XFS filesystem by writing on a special file using the values found in the arguments of the command line. It is invoked automatically by .BR mkfs (8) when it is given the .B \-t xfs option. .PP In its simplest (and most commonly used form), the size of the filesystem is determined from the disk driver. As an example, to make a filesystem with an internal log on the first partition on the first SCSI disk, use: .IP .B mkfs.xfs /dev/sda1 .PP The metadata log can be placed on another device to reduce the number of disk seeks. To create a filesystem on the first partition on the first SCSI disk with a 10000 block log located on the first partition on the second SCSI disk, use: .RS .HP .B mkfs.xfs\ \-l\ logdev=/dev/sdb1,size=10000b /dev/sda1 .RE .PP Each of the .I option elements in the argument list above can be given as multiple comma-separated suboptions if multiple suboptions apply to the same option. Equivalently, each main option can be given multiple times with different suboptions. For example, .B \-l internal,size=10000b and .B \-l internal \-l size=10000b are equivalent. .PP In the descriptions below, sizes are given in sectors, bytes, blocks, kilobytes, megabytes, gigabytes, etc. Sizes are treated as hexadecimal if prefixed by 0x or 0X, octal if prefixed by 0, or decimal otherwise. The following lists possible multiplication suffixes: .RS .PD 0 .HP .BR s "\ \-\ multiply by sector size (default = 512, see " \-s option below). .HP .BR b "\ \-\ multiply by filesystem block size (default = 4K, see " \-b option below). .HP .BR k "\ \-\ multiply by one kilobyte (1,024 bytes)." .HP .BR m "\ \-\ multiply by one megabyte (1,048,576 bytes)." .HP .BR g "\ \-\ multiply by one gigabyte (1,073,741,824 bytes)." .HP .BR t "\ \-\ multiply by one terabyte (1,099,511,627,776 bytes)." .HP .BR p "\ \-\ multiply by one petabyte (1,024 terabytes)." .HP .BR e "\ \-\ multiply by one exabyte (1,048,576 terabytes)." .PD .SH OPTIONS .TP .BI \-b " block_size_options" This option specifies the fundamental block size of the filesystem. The valid .I block_size_options are: .BI log= value or .BI size= value and only one can be supplied. The block size is specified either as a base two logarithm value with .BR log= , or in bytes with .BR size= . The default value is 4096 bytes (4 KiB), the minimum is 512, and the maximum is 65536 (64 KiB). XFS on Linux currently only supports pagesize or smaller blocks. .TP .BI \-m " global_metadata_options" These options specify metadata format options that either apply to the entire filesystem or aren't easily characterised by a specific functionality group. The valid .I global_metadata_options are: .RS 1.2i .TP .BI crc= value This is used to create a filesystem which maintains and checks CRC information in all metadata objects on disk. The value is either 0 to disable the feature, or 1 to enable the use of CRCs. .IP CRCs enable enhanced error detection due to hardware issues, whilst the format changes also improves crash recovery algorithms and the ability of various tools to validate and repair metadata corruptions when they are found. The CRC algorithm used is CRC32c, so the overhead is dependent on CPU architecture as some CPUs have hardware acceleration of this algorithm. Typically the overhead of calculating and checking the CRCs is not noticeable in normal operation. .IP By default, .B mkfs.xfs will enable metadata CRCs. .TP .BI finobt= value This option enables the use of a separate free inode btree index in each allocation group. The value is either 0 to disable the feature, or 1 to create a free inode btree in each allocation group. .IP The free inode btree mirrors the existing allocated inode btree index which indexes both used and free inodes. The free inode btree does not index used inodes, allowing faster, more consistent inode allocation performance as filesystems age. .IP By default, .B mkfs.xfs will create free inode btrees for filesystems created with the (default) .B \-m crc=1 option set. When the option .B \-m crc=0 is used, the free inode btree feature is not supported and is disabled. .TP .BI uuid= value Use the given value as the filesystem UUID for the newly created filesystem. The default is to generate a random UUID. .RE .TP .BI \-d " data_section_options" These options specify the location, size, and other parameters of the data section of the filesystem. The valid .I data_section_options are: .RS 1.2i .TP .BI agcount= value This is used to specify the number of allocation groups. The data section of the filesystem is divided into allocation groups to improve the performance of XFS. More allocation groups imply that more parallelism can be achieved when allocating blocks and inodes. The minimum allocation group size is 16 MiB; the maximum size is just under 1 TiB. The data section of the filesystem is divided into .I value allocation groups (default value is scaled automatically based on the underlying device size). .TP .BI agsize= value This is an alternative to using the .B agcount suboption. The .I value is the desired size of the allocation group expressed in bytes (usually using the .BR m " or " g suffixes). This value must be a multiple of the filesystem block size, and must be at least 16MiB, and no more than 1TiB, and may be automatically adjusted to properly align with the stripe geometry. The .B agcount and .B agsize suboptions are mutually exclusive. .TP .BI name= value This can be used to specify the name of the special file containing the filesystem. In this case, the log section must be specified as .B internal (with a size, see the .B \-l option below) and there can be no real-time section. .TP .BI file[= value ] This is used to specify that the file given by the .B name suboption is a regular file. The .I value is either 0 or 1, with 1 signifying that the file is regular. This suboption is used only to make a filesystem image. If the .I value is omitted then 1 is assumed. .TP .BI size= value This is used to specify the size of the data section. This suboption is required if .B \-d file[=1] is given. Otherwise, it is only needed if the filesystem should occupy less space than the size of the special file. .TP .BI sunit= value This is used to specify the stripe unit for a RAID device or a logical volume. The .I value has to be specified in 512-byte block units. Use the .B su suboption to specify the stripe unit size in bytes. This suboption ensures that data allocations will be stripe unit aligned when the current end of file is being extended and the file size is larger than 512KiB. Also inode allocations and the internal log will be stripe unit aligned. .TP .BI su= value This is an alternative to using .B sunit. The .B su suboption is used to specify the stripe unit for a RAID device or a striped logical volume. The .I value has to be specified in bytes, (usually using the .BR m " or " g suffixes). This .I value must be a multiple of the filesystem block size. .TP .BI swidth= value This is used to specify the stripe width for a RAID device or a striped logical volume. The .I value has to be specified in 512-byte block units. Use the .B sw suboption to specify the stripe width size in bytes. This suboption is required if .B \-d sunit has been specified and it has to be a multiple of the .B \-d sunit suboption. .TP .BI sw= value suboption is an alternative to using .B swidth. The .B sw suboption is used to specify the stripe width for a RAID device or striped logical volume. The .I value is expressed as a multiplier of the stripe unit, usually the same as the number of stripe members in the logical volume configuration, or data disks in a RAID device. .IP When a filesystem is created on a logical volume device, .B mkfs.xfs will automatically query the logical volume for appropriate .B sunit and .B swidth values. .TP .BI noalign This option disables automatic geometry detection and creates the filesystem without stripe geometry alignment even if the underlying storage device provides this information. .RE .TP .B \-f Force overwrite when an existing filesystem is detected on the device. By default, .B mkfs.xfs will not write to the device if it suspects that there is a filesystem or partition table on the device already. .TP .BI \-i " inode_options" This option specifies the inode size of the filesystem, and other inode allocation parameters. The XFS inode contains a fixed-size part and a variable-size part. The variable-size part, whose size is affected by this option, can contain: directory data, for small directories; attribute data, for small attribute sets; symbolic link data, for small symbolic links; the extent list for the file, for files with a small number of extents; and the root of a tree describing the location of extents for the file, for files with a large number of extents. .IP The valid .I inode_options are: .RS 1.2i .TP .BI size= value " | log=" value " | perblock=" value The inode size is specified either as a .I value in bytes with .BR size= , a base two logarithm .I value with .BR log= , or as the number fitting in a filesystem block with .BR perblock= . The minimum (and default) .I value is 256 bytes. The maximum .I value is 2048 (2 KiB) subject to the restriction that the inode size cannot exceed one half of the filesystem block size. .IP XFS uses 64-bit inode numbers internally; however, the number of significant bits in an inode number is affected by filesystem geometry. In practice, filesystem size and inode size are the predominant factors. The Linux kernel (on 32 bit hardware platforms) and most applications cannot currently handle inode numbers greater than 32 significant bits, so if no inode size is given on the command line, .B mkfs.xfs will attempt to choose a size such that inode numbers will be < 32 bits. If an inode size is specified, or if a filesystem is sufficiently large, .B mkfs.xfs will warn if this will create inode numbers > 32 significant bits. .TP .BI maxpct= value This specifies the maximum percentage of space in the filesystem that can be allocated to inodes. The default .I value is 25% for filesystems under 1TB, 5% for filesystems under 50TB and 1% for filesystems over 50TB. .IP In the default inode allocation mode, inode blocks are chosen such that inode numbers will not exceed 32 bits, which restricts the inode blocks to the lower portion of the filesystem. The data block allocator will avoid these low blocks to accommodate the specified maxpct, so a high value may result in a filesystem with nothing but inodes in a significant portion of the lower blocks of the filesystem. (This restriction is not present when the filesystem is mounted with the .I "inode64" option on 64-bit platforms). .IP Setting the value to 0 means that essentially all of the filesystem can become inode blocks, subject to inode32 restrictions. .IP This value can be modified with .IR xfs_growfs(8) . .TP .BI align[= value ] This is used to specify that inode allocation is or is not aligned. The .I value is either 0 or 1, with 1 signifying that inodes are allocated aligned. If the .I value is omitted, 1 is assumed. The default is that inodes are aligned. Aligned inode access is normally more efficient than unaligned access; alignment must be established at the time the filesystem is created, since inodes are allocated at that time. This option can be used to turn off inode alignment when the filesystem needs to be mountable by a version of IRIX that does not have the inode alignment feature (any release of IRIX before 6.2, and IRIX 6.2 without XFS patches). .TP .BI attr= value This is used to specify the version of extended attribute inline allocation policy to be used. By default, this is 2, which uses an efficient algorithm for managing the available inline inode space between attribute and extent data. .IP The previous version 1, which has fixed regions for attribute and extent data, is kept for backwards compatibility with kernels older than version 2.6.16. .TP .BI projid32bit[= value ] This is used to enable 32bit quota project identifiers. The .I value is either 0 or 1, with 1 signifying that 32bit projid are to be enabled. If the value is omitted, 1 is assumed. (This default changed in release version 3.2.0.) .TP .BI sparse[= value ] Enable sparse inode chunk allocation. The .I value is either 0 or 1, with 1 signifying that sparse allocation is enabled. If the value is omitted, 1 is assumed. Sparse inode allocation is disabled by default. This feature is only available for filesystems formatted with .B \-m crc=1. .IP When enabled, sparse inode allocation allows the filesystem to allocate smaller than the standard 64-inode chunk when free space is severely limited. This feature is useful for filesystems that might fragment free space over time such that no free extents are large enough to accommodate a chunk of 64 inodes. Without this feature enabled, inode allocations can fail with out of space errors under severe fragmented free space conditions. .RE .TP .BI \-l " log_section_options" These options specify the location, size, and other parameters of the log section of the filesystem. The valid .I log_section_options are: .RS 1.2i .TP .BI internal[= value ] This is used to specify that the log section is a piece of the data section instead of being another device or logical volume. The .I value is either 0 or 1, with 1 signifying that the log is internal. If the .I value is omitted, 1 is assumed. .TP .BI logdev= device This is used to specify that the log section should reside on the .I device separate from the data section. The .B internal=1 and .B logdev options are mutually exclusive. .TP .BI size= value This is used to specify the size of the log section. .IP If the log is contained within the data section and .B size isn't specified, .B mkfs.xfs will try to select a suitable log size depending on the size of the filesystem. The actual logsize depends on the filesystem block size and the directory block size. .IP Otherwise, the .B size suboption is only needed if the log section of the filesystem should occupy less space than the size of the special file. The .I value is specified in bytes or blocks, with a .B b suffix meaning multiplication by the filesystem block size, as described above. The overriding minimum value for size is 512 blocks. With some combinations of filesystem block size, inode size, and directory block size, the minimum log size is larger than 512 blocks. .TP .BI version= value This specifies the version of the log. The current default is 2, which allows for larger log buffer sizes, as well as supporting stripe-aligned log writes (see the sunit and su options, below). .IP The previous version 1, which is limited to 32k log buffers and does not support stripe-aligned writes, is kept for backwards compatibility with very old 2.4 kernels. .TP .BI sunit= value This specifies the alignment to be used for log writes. The .I value has to be specified in 512-byte block units. Use the .B su suboption to specify the log stripe unit size in bytes. Log writes will be aligned on this boundary, and rounded up to this boundary. This gives major improvements in performance on some configurations such as software RAID5 when the .B sunit is specified as the filesystem block size. The equivalent byte value must be a multiple of the filesystem block size. Version 2 logs are automatically selected if the log .B sunit suboption is specified. .IP The .B su suboption is an alternative to using .B sunit. .TP .BI su= value This is used to specify the log stripe. The .I value has to be specified in bytes, (usually using the .BR s " or " b suffixes). This value must be a multiple of the filesystem block size. Version 2 logs are automatically selected if the log .B su suboption is specified. .TP .BI lazy-count= value This changes the method of logging various persistent counters in the superblock. Under metadata intensive workloads, these counters are updated and logged frequently enough that the superblock updates become a serialization point in the filesystem. The .I value can be either 0 or 1. .IP With .BR lazy-count=1 , the superblock is not modified or logged on every change of the persistent counters. Instead, enough information is kept in other parts of the filesystem to be able to maintain the persistent counter values without needed to keep them in the superblock. This gives significant improvements in performance on some configurations. The default .I value is 1 (on) so you must specify .B lazy-count=0 if you want to disable this feature for older kernels which don't support it. .RE .TP .BI \-n " naming_options" These options specify the version and size parameters for the naming (directory) area of the filesystem. The valid .I naming_options are: .RS 1.2i .TP .BI size= value " | log=" value The block size is specified either as a .I value in bytes with .BR size= , or as a base two logarithm .I value .RB "with " log= . The block size must be a power of 2 and cannot be less than the filesystem block size. The default size .I value for version 2 directories is 4096 bytes (4 KiB), unless the filesystem block size is larger than 4096, in which case the default .I value is the filesystem block size. For version 1 directories the block size is the same as the filesystem block size. .TP .BI version= value The naming (directory) version .I value can be either 2 or 'ci', defaulting to 2 if unspecified. With version 2 directories, the directory block size can be any power of 2 size from the filesystem block size up to 65536. .IP The .B version=ci option enables ASCII only case-insensitive filename lookup and version 2 directories. Filenames are case-preserving, that is, the names are stored in directories using the case they were created with. .IP Note: Version 1 directories are not supported. .TP .BI ftype= value This feature allows the inode type to be stored in the directory structure so that the .BR readdir (3) and .BR getdents (2) do not need to look up the inode to determine the inode type. The .I value is either 0 or 1, with 1 signifiying that filetype information will be stored in the directory structure. The default value is 0. When CRCs are enabled via .B \-m crc=1, the ftype functionality is always enabled. This feature can not be turned off for such filesystem configurations. .IP .RE .TP .BI \-p " protofile" If the optional .BI \-p " protofile" argument is given, .B mkfs.xfs uses .I protofile as a prototype file and takes its directions from that file. The blocks and inodes specifiers in the .I protofile are provided for backwards compatibility, but are otherwise unused. The syntax of the protofile is defined by a number of tokens separated by spaces or newlines. Note that the line numbers are not part of the syntax but are meant to help you in the following discussion of the file contents. .nf .sp .8v .in +5 \f71 /stand/\f1\f2diskboot\f1\f7 2 4872 110 3 d\-\-777 3 1 4 usr d\-\-777 3 1 5 sh \-\-\-755 3 1 /bin/sh 6 ken d\-\-755 6 1 7 $ 8 b0 b\-\-644 3 1 0 0 9 c0 c\-\-644 3 1 0 0 10 fifo p\-\-644 3 1 11 slink l\-\-644 3 1 /a/symbolic/link 12 : This is a comment line 13 $ 14 $\f1 .in -5 .fi .IP Line 1 is a dummy string. (It was formerly the bootfilename.) It is present for backward compatibility; boot blocks are not used on SGI systems. .IP Note that some string of characters must be present as the first line of the proto file to cause it to be parsed correctly; the value of this string is immaterial since it is ignored. .IP Line 2 contains two numeric values (formerly the numbers of blocks and inodes). These are also merely for backward compatibility: two numeric values must appear at this point for the proto file to be correctly parsed, but their values are immaterial since they are ignored. .IP The lines 3 through 11 specify the files and directories you want to include in this filesystem. Line 3 defines the root directory. Other directories and files that you want in the filesystem are indicated by lines 4 through 6 and lines 8 through 10. Line 11 contains symbolic link syntax. .IP Notice the dollar sign .RB ( $ ) syntax on line 7. This syntax directs the .B mkfs.xfs command to terminate the branch of the filesystem it is currently on and then continue from the directory specified by the next line, in this case line 8. It must be the last character on a line. The colon on line 12 introduces a comment; all characters up until the following newline are ignored. Note that this means you cannot have a file in a prototype file whose name contains a colon. The .B $ on lines 13 and 14 end the process, since no additional specifications follow. .IP File specifications provide the following: .IP * file mode .br * user ID .br * group ID .br * the file's beginning contents .P .IP A 6-character string defines the mode for a file. The first character of this string defines the file type. The character range for this first character is .B \-bcdpl. A file may be a regular file, a block special file, a character special file, directory files, named pipes (first-in, first out files), and symbolic links. The second character of the mode string is used to specify setuserID mode, in which case it is .BR u . If setuserID mode is not specified, the second character is .BR \- . The third character of the mode string is used to specify the setgroupID mode, in which case it is .BR g . If setgroupID mode is not specified, the third character is .BR \- . The remaining characters of the mode string are a three digit octal number. This octal number defines the owner, group, and other read, write, and execute permissions for the file, respectively. For more information on file permissions, see the .BR chmod (1) command. .IP Following the mode character string are two decimal number tokens that specify the user and group IDs of the file's owner. .IP In a regular file, the next token specifies the pathname from which the contents and size of the file are copied. In a block or character special file, the next token are two decimal numbers that specify the major and minor device numbers. When a file is a symbolic link, the next token specifies the contents of the link. When the file is a directory, the .B mkfs.xfs command creates the entries .B dot (.) and .B dot-dot (..) and then reads the list of names and file specifications in a recursive manner for all of the entries in the directory. A scan of the protofile is always terminated with the dollar ( .B $ ) token. .TP .B \-q Quiet option. Normally .B mkfs.xfs prints the parameters of the filesystem to be constructed; the .B \-q flag suppresses this. .TP .BI \-r " realtime_section_options" These options specify the location, size, and other parameters of the real-time section of the filesystem. The valid .I realtime_section_options are: .RS 1.2i .TP .BI rtdev= device This is used to specify the .I device which should contain the real-time section of the filesystem. The suboption value is the name of a block device. .TP .BI extsize= value This is used to specify the size of the blocks in the real-time section of the filesystem. This .I value must be a multiple of the filesystem block size. The minimum allowed size is the filesystem block size or 4 KiB (whichever is larger); the default size is the stripe width for striped volumes or 64 KiB for non-striped volumes; the maximum allowed size is 1 GiB. The real-time extent size should be carefully chosen to match the parameters of the physical media used. .TP .BI size= value This is used to specify the size of the real-time section. This suboption is only needed if the real-time section of the filesystem should occupy less space than the size of the partition or logical volume containing the section. .TP .BI noalign This option disables stripe size detection, enforcing a realtime device with no stripe geometry. .RE .TP .BI \-s " sector_size" This option specifies the fundamental sector size of the filesystem. The .I sector_size is specified either as a value in bytes with .BI size= value or as a base two logarithm value with .BI log= value. The default .I sector_size is 512 bytes. The minimum value for sector size is 512; the maximum is 32768 (32 KiB). The .I sector_size must be a power of 2 size and cannot be made larger than the filesystem block size. .TP .BI \-L " label" Set the filesystem .IR label .

Instead, enough information is kept in other parts of the filesystem to be able to maintain the counter values without needing to keep them in the superblock. This gives significant improvements in performance on some configurations and metadata intensive workloads. .TP .BI \-L " label" Set the filesystem label to .IR label . XFS filesystem labels can be at most 12 characters long; if .I label is longer than 12 characters, .B xfs_admin will truncate it and print a warning message.

A sample UUID looks like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The .I uuid may also be .BR nil , which will set the filesystem UUID to the null UUID. The .I uuid may also be .BR generate , which will generate a new UUID for the filesystem.

The first .RI ( source ) argument must be the pathname of the device or file containing the XFS filesystem. The remaining arguments specify one or more .I target devices or file names. If the pathnames specify devices, a copy of the source XFS filesystem is created on each device. The .I target can also be the name of a regular file, in which case an image of the source XFS filesystem is created in that file. If the file does not exist, .B xfs_copy creates the file. The length of the resulting file is equal to the size of the source filesystem. However, if the file is created on an XFS filesystem, the file consumes roughly the amount of space actually used in the source filesystem by the filesystem and the XFS log. The space saving is because .B xfs_copy seeks over free blocks instead of copying them and the XFS filesystem supports sparse files efficiently. .PP .B xfs_copy should only be used to copy unmounted filesystems, read-only mounted filesystems, or frozen filesystems (see .BR xfs_freeze (8)). Otherwise, the generated filesystem(s) would be inconsistent or corrupt. .PP .B xfs_copy does not alter the source filesystem in any way. Each new (target) filesystem is identical to the original filesystem except that new filesystems each have a new unique filesystem identifier (UUID). Therefore, if both the old and new filesystems will be used as separate distinct filesystems, .B xfs_copy or .BR xfsdump (8)/ xfsrestore (8) should be used to generate the new filesystem(s) instead of .BR dd (1) or other programs that do block-by-block disk copying. .PP .B xfs_copy uses synchronous writes to ensure that write errors are detected. .PP .B xfs_copy uses .BR pthreads (7) to perform simultaneous parallel writes. .B xfs_copy creates one additional thread for each target to be written. All threads die if .B xfs_copy terminates or aborts. .SH OPTIONS .TP .B \-d Create a duplicate (true clone) filesystem. This should be done only if the new filesystem will be used as a replacement for the original filesystem (such as in the case of disk replacement). .TP .B \-b The buffered option can be used to ensure direct IO is not attempted to any of the target files. This is useful when the filesystem holding the target file does not support direct IO. .TP .BI \-L " log" Specifies the location of the .I log if the default location of .I /var/tmp/xfs_copy.log.XXXXXX is not desired. .TP .B \-V Prints the version number and exits. .SH DIAGNOSTICS .B xfs_copy reports errors to both .B stderr and in more detailed form to a generated log file whose name is of the form .I /var/tmp/xfs_copy.log.XXXXXX or a log file specified by the .B \-L option. If .B xfs_copy detects a write error on a target, the copy of that one target is aborted and an error message is issued to both stderr and the log file, but the rest of the copies continue. When .B xfs_copy terminates, all aborted targets are reported to both .B stderr and the log file. .PP If all targets abort or if there is an error reading the source filesystem, .B xfs_copy immediately aborts. .PP .B xfs_copy returns an exit code of 0 if all targets are successfully copied and an exit code of 1 if any target fails. .SH NOTES When moving filesystems from one disk to another, if the original filesystem is significantly smaller than the new filesystem, and will be made larger, we recommend that .BR mkfs.xfs "(8) and " xfsdump (8)/ xfsrestore (8) be used instead of using .B xfs_copy and .BR xfs_growfs (8). The filesystem layout resulting from using .BR xfs_copy / xfs_growfs is almost always worse than the result of using .BR mkfs.xfs / xfsdump / xfsrestore but in the case of small filesystems, the differences can have a significant performance impact. This is due to the way .BR xfs_growfs (8) works, and not due to any shortcoming in .B xfs_copy itself. .SH CAVEATS .B xfs_copy does not copy XFS filesystems that have a real-time section or XFS filesystems with external logs. In both cases, .B xfs_copy aborts with an error message. .SH SEE ALSO .BR mkfs.xfs (8), .BR xfsdump (8), .BR xfsrestore (8), .BR xfs_freeze (8), .BR xfs_growfs (8), .BR xfs (5). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_db.80000664000000000000000000013161212625713772015614 0ustar .TH xfs_db 8 .SH NAME xfs_db \- debug an XFS filesystem .SH SYNOPSIS .B xfs_db [ .B \-c .I cmd ] ...

Under rare circumstances it can also be used to modify an XFS filesystem, but that task is normally left to .BR xfs_repair (8) or to scripts such as .BR xfs_admin (8) that run .BR xfs_db . .PP .SH OPTIONS .TP .BI \-c " cmd" .B xfs_db commands may be run interactively (the default) or as arguments on the command line. Multiple .B \-c arguments may be given. The commands are run in the sequence given, then the program exits. .TP .B \-f Specifies that the filesystem image to be processed is stored in a regular file at .I device (see the .BR mkfs.xfs "(8) " -d .I file option). This might happen if an image copy of a filesystem has been made into an ordinary file with .BR xfs_copy (8). .TP .B \-F Specifies that we want to continue even if the superblock magic is not correct. For use in .BR xfs_metadump . .TP .B \-i Allows execution on a mounted filesystem, provided it is mounted read-only. Useful for shell scripts which must only operate on filesystems in a guaranteed consistent state (either unmounted or mounted read-only). These semantics are slightly different to that of the .B -r option. .TP .BI \-l " logdev" Specifies the device where the filesystems external log resides. Only for those filesystems which use an external log. See the .BR mkfs.xfs "(8) " \-l option, and refer to .BR xfs (5) for a detailed description of the XFS log. .TP .BI \-p " progname" Set the program name to .I progname for prompts and some error messages, the default value is .BR xfs_db . .TP .B -r Open .I device or .I filename read-only. This option is required if the filesystem is mounted. It is only necessary to omit this flag if a command that changes data .RB ( write ", " blocktrash ) is to be used. .TP .B \-x Specifies expert mode. This enables the .B write and .B blocktrash commands. .TP .B \-V Prints the version number and exits. .SH CONCEPTS .B xfs_db commands can be broken up into two classes. Most commands are for the navigation and display of data structures in the filesystem. Other commands are for scanning the filesystem in some way. .PP Commands which are used to navigate the filesystem structure take arguments which reflect the names of filesystem structure fields. There can be multiple field names separated by dots when the underlying structures are nested, as in C. The field names can be indexed (as an array index) if the underlying field is an array. The array indices can be specified as a range, two numbers separated by a dash. .PP .B xfs_db maintains a current address in the filesystem. The granularity of the address is a filesystem structure. This can be a filesystem block, an inode or quota (smaller than a filesystem block), or a directory block (could be larger than a filesystem block). There are a variety of commands to set the current address. Associated with the current address is the current data type, which is the structural type of this data. Commands which follow the structure of the filesystem always set the type as well as the address. Commands which examine pieces of an individual file (inode) need the current inode to be set, this is done with the .B inode command. .PP The current address/type information is actually maintained in a stack that can be explicitly manipulated with the .BR push ", " pop ", and " stack commands. This allows for easy examination of a nested filesystem structure. Also, the last several locations visited are stored in a ring buffer which can be manipulated with the .BR forward ", " back ", and " ring commands. .PP XFS filesystems are divided into a small number of allocation groups. .B xfs_db maintains a notion of the current allocation group which is manipulated by some commands. The initial allocation group is 0. .SH COMMANDS .PP Many commands have extensive online help. Use the .B help command for more details on any command. .TP .B a See the .B addr command. .TP .BI ablock " filoff" Set current address to the offset .I filoff (a filesystem block number) in the attribute area of the current inode. .TP .BI "addr [" field-expression ] Set current address to the value of the .IR field-expression . This is used to "follow" a reference in one structure to the object being referred to. If no argument is given, the current address is printed. .TP .BI "agf [" agno ] Set current address to the AGF block for allocation group .IR agno . If no argument is given, use the current allocation group. .TP .BI "agfl [" agno ] Set current address to the AGFL block for allocation group .IR agno . If no argument is given, use the current allocation group. .TP .BI "agi [" agno ] Set current address to the AGI block for allocation group .IR agno . If no argument is given, use the current allocation group. .TP .B b See the .B back command. .TP .B back Move to the previous location in the position ring. .TP .B blockfree Free block usage information collected by the last execution of the .B blockget command. This must be done before another .B blockget command can be given, presumably with different arguments than the previous one. .TP .BI "blockget [\-npvs] [\-b " bno "] ... [\-i " ino "] ..." Get block usage and check filesystem consistency. The information is saved for use by a subsequent .BR blockuse ", " ncheck ", or " blocktrash command. .RS 1.0i .TP 0.4i .B \-b is used to specify filesystem block numbers about which verbose information should be printed. .TP .B \-i is used to specify inode numbers about which verbose information should be printed. .TP .B \-n is used to save pathnames for inodes visited, this is used to support the .BR xfs_ncheck (8) command. It also means that pathnames will be printed for inodes that have problems. This option uses a lot of memory so is not enabled by default. .TP .B \-p causes error messages to be prefixed with the filesystem name being processed. This is useful if several copies of .B xfs_db are run in parallel. .TP .B \-s restricts output to severe errors only. This is useful if the output is too long otherwise. .TP .B \-v enables verbose output.

If the value is preceded by a '+', the trashing will start at a randomly chosen offset that is larger than the value supplied. The default is to randomly choose an offset anywhere in the block. .TP .B \-s supplies a .I seed to the random processing. .TP .B \-t gives a .I type of blocks to be selected for trashing. Multiple .B \-t options may be given. If no .B \-t options are given then all metadata types can be trashed. .TP .B \-x sets the .I minimum size of bit range to be trashed. The default value is 1. .TP .B \-y sets the .I maximum size of bit range to be trashed. The default value is 1024. .TP .B \-z trashes the block at the top of the stack.

See the TYPES section below for more information on these data types. .TP .BI "uuid [" uuid " | " generate " | " rewrite " | " restore ] Set the filesystem universally unique identifier (UUID). The filesystem UUID can be used by .BR mount (8) instead of using a device special file. The .I uuid can be set directly to the desired UUID, or it can be automatically generated using the .B generate option. These options will both write the UUID into every copy of the superblock in the filesystem. On a CRC-enabled filesystem, this will set an incompatible superblock flag, and the filesystem will not be mountable with older kernels. This can be reverted with the .B restore option, which will copy the original UUID back into place and clear the incompatible flag as needed. .B rewrite copies the current UUID from the primary superblock to all secondary copies of the superblock. If no argument is given, the current filesystem UUID is printed. .TP .BI "version [" feature " | " "versionnum features2" ] Enable selected features for a filesystem (certain features can be enabled on an unmounted filesystem, after .BR mkfs.xfs (8) has created the filesystem). Support for unwritten extents can be enabled using the .B extflg option. Support for version 2 log format can be enabled using the .B log2 option. Support for extended attributes can be enabled using the .B attr1 or .B attr2 option. Once enabled, extended attributes cannot be disabled, but the user may toggle between .B attr1 and .B attr2 at will (older kernels may not support the newer version). .IP If no argument is given, the current version and feature bits are printed. With one argument, this command will write the updated version number into every copy of the superblock in the filesystem. If two arguments are given, they will be used as numeric values for the .I versionnum and .I features2 bits respectively, and their string equivalent reported (but no modifications are made). .TP .BI "write [\-c] [" "field value" "] ..." Write a value to disk. Specific fields can be set in structures (struct mode), or a block can be set to data values (data mode), or a block can be set to string values (string mode, for symlink blocks). The operation happens immediately: there is no buffering. .IP Struct mode is in effect when the current type is structural, i.e. not data. For struct mode, the syntax is "\c .B write .I field value\c ". .IP Data mode is in effect when the current type is data. In this case the contents of the block can be shifted or rotated left or right, or filled with a sequence, a constant value, or a random value.

Each inode contains four regions: .BR core , .BR next_unlinked , .BR u ", and " .BR a . .B core contains the fixed information. .B next_unlinked is separated from the core due to journaling considerations, see type .B agi field .BR unlinked . .B u is a union structure that is different in size and format depending on the type and representation of the file data ("data fork"). .B a is an optional union structure to describe attribute data, that is different in size, format, and location depending on the presence and representation of attribute data, and the size of the .B u data ("attribute fork"). .B xfs_db automatically selects the proper union members based on information in the inode. .IP The following are fields in the inode core: .RS 1.4i .PD 0 .TP 1.2i .B magic inode magic number, 0x494e ('IN'). .TP .B mode mode and type of file, as described in .BR chmod (2), .BR mknod (2), and .BR stat (2). .TP .B version inode version, 1 or 2. .TP .B format format of .B u union data (0: xfs_dev_t, 1: local file \- in-inode directory or symlink, 2: extent list, 3: Btree root, 4: unique id [unused]). .TP .B nlinkv1 number of links to the file in a version 1 inode. .TP .B nlinkv2 number of links to the file in a version 2 inode. .TP .B projid_lo owner's project id (low word; version 2 inode only). .B projid_hi owner's project id (high word; version 2 inode only). .TP .B uid owner's user id. .TP .B gid owner's group id. .TP .B atime time last accessed (seconds and nanoseconds). .TP .B mtime time last modified. .TP .B ctime time created or inode last modified. .TP .B size number of bytes in the file. .TP .B nblocks total number of blocks in the file including indirect and attribute. .TP .B extsize basic/minimum extent size for the file. .TP .B nextents number of extents in the data fork. .TP .B naextents number of extents in the attribute fork. .TP .B forkoff attribute fork offset in the inode, in 64-bit words from the start of .BR u . .TP .B aformat format of .B a data (1: local attribute data, 2: extent list, 3: Btree root). .TP .B dmevmask DMAPI event mask. .TP .B dmstate DMAPI state information. .TP .B newrtbm file is the realtime bitmap and is "new" format. .TP .B prealloc file has preallocated data space after EOF. .TP .B realtime file data is in the realtime subvolume. .TP .B gen inode generation number. .RE .IP The following fields are in the .B u data fork union: .RS 1.4i .TP 1.2i .B bmbt bmap Btree root. This looks like a .B bmapbtd block with redundant information removed. .TP .B bmx array of extent descriptors. .TP .B dev dev_t for the block or character device. .TP .B sfdir shortform (in-inode) version 1 directory. This consists of a .B hdr containing the .B parent inode number and a .B count of active entries in the directory, followed by an array .B list of .B hdr.count entries. Each such entry contains .BR inumber , .BR namelen , and .B name string. .TP .B sfdir2 shortform (in-inode) version 2 directory. This consists of a .B hdr containing a .B count of active entries in the directory, an .B i8count of entries with inumbers that don't fit in a 32-bit value, and the .B parent inode number, followed by an array .B list of .B hdr.count entries. Each such entry contains .BR namelen , a saved .B offset used when the directory is converted to a larger form, a .B name string, and the .BR inumber . .TP .B symlink symbolic link string value. .RE .IP The following fields are in the .B a attribute fork union if it exists: .RS 1.4i .TP 1.2i .B bmbt bmap Btree root, as above. .TP .B bmx array of extent descriptors. .TP .B sfattr shortform (in-inode) attribute values. This consists of a .B hdr containing a .B totsize (total size in bytes) and a .B count of active entries, followed by an array .B list of .B hdr.count entries. Each such entry contains .BR namelen , .BR valuelen , .BR root flag, .BR name , and .BR value . .PD .RE .TP .B log Log blocks contain the journal entries for XFS. It's not useful to examine these with .BR xfs_db , use .BR xfs_logprint (8) instead. .TP .B rtbitmap If the filesystem has a realtime subvolume, then the .B rbmino field in the superblock refers to a file that contains the realtime bitmap. Each bit in the bitmap file controls the allocation of a single realtime extent (set == free). The bitmap is processed in 32-bit words, the LSB of a word is used for the first extent controlled by that bitmap word. The .B atime field of the realtime bitmap inode contains a counter that is used to control where the next new realtime file will start. .TP .B rtsummary If the filesystem has a realtime subvolume, then the .B rsumino field in the superblock refers to a file that contains the realtime summary data. The summary file contains a two-dimensional array of 16-bit values. Each value counts the number of free extent runs (consecutive free realtime extents) of a given range of sizes that starts in a given bitmap block. The size ranges are binary buckets (low size in the bucket is a power of 2). There are as many size ranges as are necessary given the size of the realtime subvolume. The first dimension is the size range, the second dimension is the starting bitmap block number (adjacent entries are for the same size, adjacent bitmap blocks). .TP .B sb There is one sb (superblock) structure per allocation group. It is the first disk block in the allocation group. Only the first one (block 0 of the filesystem) is actually used; the other blocks are redundant information for .BR xfs_repair (8) to use if the first superblock is damaged. Fields defined: .RS 1.4i .PD 0 .TP 1.2i .B magicnum superblock magic number, 0x58465342 ('XFSB'). .TP .B blocksize filesystem block size in bytes. .TP .B dblocks number of filesystem blocks present in the data subvolume. .TP .B rblocks number of filesystem blocks present in the realtime subvolume. .TP .B rextents number of realtime extents that .B rblocks contain. .TP .B uuid unique identifier of the filesystem. .TP .B logstart starting filesystem block number of the log (journal). If this value is 0 the log is "external". .TP .B rootino root inode number. .TP .B rbmino realtime bitmap inode number. .TP .B rsumino realtime summary data inode number. .TP .B rextsize realtime extent size in filesystem blocks. .TP .B agblocks size of an allocation group in filesystem blocks. .TP .B agcount number of allocation groups. .TP .B rbmblocks number of realtime bitmap blocks. .TP .B logblocks number of log blocks (filesystem blocks). .TP .B versionnum filesystem version information. This value is currently 1, 2, 3, or 4 in the low 4 bits. If the low bits are 4 then the other bits have additional meanings. 1 is the original value. 2 means that attributes were used. 3 means that version 2 inodes (large link counts) were used. 4 is the bitmask version of the version number. In this case, the other bits are used as flags (0x0010: attributes were used, 0x0020: version 2 inodes were used, 0x0040: quotas were used, 0x0080: inode cluster alignment is in force, 0x0100: data stripe alignment is in force, 0x0200: the .B shared_vn field is used, 0x1000: unwritten extent tracking is on, 0x2000: version 2 directories are in use). .TP .B sectsize sector size in bytes, currently always 512. This is the size of the superblock and the other header blocks. .TP .B inodesize inode size in bytes. .TP .B inopblock number of inodes per filesystem block. .TP .B fname obsolete, filesystem name. .TP .B fpack obsolete, filesystem pack name. .TP .B blocklog log2 of .BR blocksize . .TP .B sectlog log2 of .BR sectsize . .TP .B inodelog log2 of .BR inodesize . .TP .B inopblog log2 of .BR inopblock . .TP .B agblklog log2 of .B agblocks (rounded up). .TP .B rextslog log2 of .BR rextents . .TP .B inprogress .BR mkfs.xfs (8) or .BR xfs_copy (8) aborted before completing this filesystem. .TP .B imax_pct maximum percentage of filesystem space used for inode blocks. .TP .B icount number of allocated inodes. .TP .B ifree number of allocated inodes that are not in use. .TP .B fdblocks number of free data blocks. .TP .B frextents number of free realtime extents. .TP .B uquotino user quota inode number. .TP .B pquotino project quota inode number; this is currently unused. .TP .B qflags quota status flags (0x01: user quota accounting is on, 0x02: user quota limits are enforced, 0x04: quotacheck has been run on user quotas, 0x08: project quota accounting is on, 0x10: project quota limits are enforced, 0x20: quotacheck has been run on project quotas). .TP .B flags random flags. 0x01: only read-only mounts are allowed. .TP .B shared_vn shared version number (shared readonly filesystems). .TP .B inoalignmt inode chunk alignment in filesystem blocks. .TP .B unit stripe or RAID unit. .TP .B width stripe or RAID width. .TP .B dirblklog log2 of directory block size (filesystem blocks). .PD .RE .TP .B symlink Symbolic link blocks are used only when the symbolic link value does not fit inside the inode. The block content is just the string value. Bytes past the logical end of the symbolic link value have arbitrary values. .TP .B text User file blocks, and other blocks whose type is unknown, have this type for display purposes in .BR xfs_db . The block data is displayed in two columns: Hexadecimal format and printable ASCII chars. .SH DIAGNOSTICS Many messages can come from the .B check .RB ( blockget ) command. If the filesystem is completely corrupt, a core dump might be produced instead of the message .RS .I device .B is not a valid filesystem .RE .PP If the filesystem is very large (has many files) then .B check might run out of memory.

The filesystem must be mounted to be frozen (see .BR mount (8)). .PP .PP The .B \-f flag requests the specified XFS filesystem to be frozen from new modifications. When this is selected, all ongoing transactions in the filesystem are allowed to complete, new write system calls are halted, other calls which modify the filesystem are halted, and all dirty data, metadata, and log information are written to disk. Any process attempting to write to the frozen filesystem will block waiting for the filesystem to be unfrozen. .PP Note that even after freezing, the on-disk filesystem can contain information on files that are still in the process of unlinking. These files will not be unlinked until the filesystem is unfrozen or a clean mount of the snapshot is complete. .PP The .B \-u flag is used to un-freeze the filesystem and allow operations to continue. Any filesystem modifications that were blocked by the freeze are unblocked and allowed to complete. .PP The .B \-V flag prints the version number and exits. .PP Unless .B \-V is specified, one of .B \-f or .B \-u must be supplied to .BR xfs_freeze . .SH NOTES A copy of a frozen XFS filesystem will usually have the same universally unique identifier (UUID) as the original, and thus may be prevented from being mounted. The XFS .B nouuid mount option can be used to circumvent this issue. .PP In Linux kernel version 2.6.29, the interface which XFS uses to freeze and unfreeze was elevated to the VFS, so that this tool can now be used on many other Linux filesystems. .SH SEE ALSO .BR xfs (5), .BR lvm (8), .BR mount (8). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_fsr.80000664000000000000000000001210012560572026016000 0ustar .TH xfs_fsr 8 .SH NAME xfs_fsr \- filesystem reorganizer for XFS .SH SYNOPSIS .nf \f3xfs_fsr\f1 [\f3\-vdg\f1] \c [\f3\-t\f1 seconds] [\f3\-p\f1 passes] [\f3\-f\f1 leftoff] [\f3\-m\f1 mtab] \f3xfs_fsr\f1 [\f3\-vdg\f1] \c [xfsdev | file] ... .br .B xfs_fsr \-V .fi .SH DESCRIPTION .I xfs_fsr is applicable only to XFS filesystems. .PP .I xfs_fsr improves the organization of mounted filesystems. The reorganization algorithm operates on one file at a time, compacting or otherwise improving the layout of the file extents (contiguous blocks of file data). .PP The following options are accepted by .IR xfs_fsr . The .BR \-m , .BR \-t , and .B \-f options have no meaning if any filesystems or files are specified on the command line. .TP 13 .BI \-m " mtab" Use this file for the list of filesystems to reorganize. The default is to use .IR /etc/mtab . .TP .BI \-t " seconds" How long to reorganize. The default is 7200 seconds (2 hours). .TP .BI \-p " passes" Number of passes before terminating global re-org. The default is 10 passes. .TP .BI \-f " leftoff" Use this file instead of .I /var/tmp/.fsrlast to read the state of where to start and as the file to store the state of where reorganization left off. .TP .B \-v Verbose. Print cryptic information about each file being reorganized. .TP .B \-d Debug. Print even more cryptic information. .TP .B \-g Print to syslog (default if stdout not a tty). .TP .B \-V Prints the version number and exits. .PP When invoked with no arguments .I xfs_fsr reorganizes all regular files in all mounted filesystems. .I xfs_fsr makes many cycles over .I /etc/mtab each time making a single pass over each XFS filesystem. Each pass goes through and selects files that have the largest number of extents. It attempts to defragment the top 10% of these files on each pass. .PP It runs for up to two hours after which it records the filesystem where it left off, so it can start there the next time. This information is stored in the file .I /var/tmp/.fsrlast_xfs. If the information found here is somehow inconsistent or out of date it is ignored and reorganization starts at the beginning of the first filesystem found in .IR /etc/mtab . .PP .I xfs_fsr can be called with one or more arguments naming filesystems (block device name), and files to reorganize. In this mode .I xfs_fsr does not read or write .I /var/tmp/.fsrlast_xfs nor does it run for a fixed time interval. It makes one pass through each specified regular file and all regular files in each specified filesystem. A command line name referring to a symbolic link (except to a file system device), FIFO, or UNIX domain socket generates a warning message, but is otherwise ignored. While traversing the filesystem these types of files are silently skipped. .SH FILES .PD 0 .TP 21 /etc/mtab contains default list of filesystems to reorganize. .TP 21 /var/tmp/.fsrlast_xfs records the state where reorganization left off. .PD .SH "SEE ALSO" xfs_fsr(8), mkfs.xfs(8), xfs_ncheck(8), xfs(5). .SH "NOTES" .I xfs_fsr improves the layout of extents for each file by copying the entire file to a temporary location and then interchanging the data extents of the target and temporary files in an atomic manner. This method requires that enough free disk space be available to copy any given file and that the space be less fragmented than the original file. It also requires the owner of the file to have enough remaining filespace quota to do the copy on systems running quotas. .I xfs_fsr generates a warning message if space is not sufficient to improve the target file. .PP A temporary file used in improving a file given on the command line is created in the same parent directory of the target file and is prefixed by the string '\f3.fsr\f1'. The temporary files used in improving an entire XFS device are stored in a directory at the root of the target device and use the same naming scheme. The temporary files are unlinked upon creation so data will not be readable by any other process. .PP .I xfs_fsr does not operate on files that are currently mapped in memory. A 'file busy' error can be seen for these files if the verbose flag (\f3-v\f1) is set. .PP Files marked as no\-defrag will be skipped. The .IR xfs_io (8) chattr command with the f attribute can be used to set or clear this flag. Files and directories created in a directory with the no\-defrag flag will inherit the attribute. .PP An entry in .I /etc/mtab or the file specified using the .B \-m option must have the .B rw option specified for read and write access. If this option is not present, then .I xfs_fsr skips the filesystem described by that line. See the .IR fstab (5) reference page for more details. .PP In general we do not foresee the need to run .I xfs_fsr on system partitions such as .IR / , .I /boot and .I /usr as in general these will not suffer from fragmentation. There are also issues with defragmenting files .IR lilo (8) uses to boot your system. It is recommended that these files should be flagged as no\-defrag with the .IR xfs_io (8) chattr command. Should these files be moved by .I xfs_fsr then you must rerun .I lilo before you reboot or you may have an unbootable system. xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_growfs.80000664000000000000000000001145712560572026016533 0ustar .\" Verbatim blocks taken from openssl req manpage content .de Vb \" Begin verbatim text .ft CW .nf .ne \\$1 .. .de Ve \" End verbatim text .ft R .fi .. .TH xfs_growfs 8 .SH NAME xfs_growfs, xfs_info \- expand an XFS filesystem .SH SYNOPSIS .B xfs_growfs [ .B \-dilnrx ] [ .B \-D .I size ] [ .B \-e .I rtextsize ] [ .B \-L .I size ] [ .B \-m .I maxpct ] [ .B \-t .I mtab ] [ .B \-R .I size ] .I mount-point .br .B xfs_growfs \-V .PP .br .B xfs_info [ .B \-t .I mtab ] .I mount-point .br .B xfs_info \-V .SH DESCRIPTION .B xfs_growfs expands an existing XFS filesystem (see .BR xfs (5)). The .I mount-point argument is the pathname of the directory where the filesystem is mounted. The filesystem must be mounted to be grown (see .BR mount (8)). The existing contents of the filesystem are undisturbed, and the added space becomes available for additional file storage. .PP .B xfs_info is equivalent to invoking .B xfs_growfs with the .B \-n option (see discussion below). .SH OPTIONS .TP .BI "\-d | \-D " size Specifies that the data section of the filesystem should be grown. If the .B \-D .I size option is given, the data section is grown to that .IR size , otherwise the data section is grown to the largest size possible with the .B \-d option. The size is expressed in filesystem blocks. .TP .B \-e Allows the real-time extent size to be specified. In .BR mkfs.xfs (8) this is specified with .B \-r extsize=\c .IR nnnn . .TP .B \-i The new log is an internal log (inside the data section). .B [NOTE: This option is not implemented] .TP .BI "\-l | \-L " size Specifies that the log section of the filesystem should be grown, shrunk, or moved. If the .B \-L .I size option is given, the log section is changed to be that .IR size , if possible. The size is expressed in filesystem blocks. The size of an internal log must be smaller than the size of an allocation group (this value is printed at .BR mkfs (8) time). If neither .B \-i nor .B \-x is given with .BR \-l , the log continues to be internal or external as it was before. .B [NOTE: These options are not implemented] .TP .B \-m Specify a new value for the maximum percentage of space in the filesystem that can be allocated as inodes. In .BR mkfs.xfs (8) this is specified with .B -i maxpct=\c .IR nn . .TP .B \-n Specifies that no change to the filesystem is to be made. The filesystem geometry is printed, and argument checking is performed, but no growth occurs. .B See output examples below. .TP .BI "\-r | \-R " size Specifies that the real-time section of the filesystem should be grown. If the .B \-R .I size option is given, the real-time section is grown to that size, otherwise the real-time section is grown to the largest size possible with the .B \-r option. The size is expressed in filesystem blocks. The filesystem does not need to have contained a real-time section before the .B xfs_growfs operation. .TP .B \-t Specifies an alternate mount table file (default is .I /proc/mounts if it exists, else .IR /etc/mtab ). This is used when working with filesystems mounted without writing to .I /etc/mtab file - refer to .BR mount (8) for further details. .TP .B \-V Prints the version number and exits. The .I mount-point argument is not required with .BR \-V . .PP .B xfs_growfs is most often used in conjunction with logical volumes (see .BR md (4) and .BR lvm (8) on Linux). However, it can also be used on a regular disk partition, for example if a partition has been enlarged while retaining the same starting block. .SH PRACTICAL USE Filesystems normally occupy all of the space on the device where they reside. In order to grow a filesystem, it is necessary to provide added space for it to occupy. Therefore there must be at least one spare new disk partition available. Adding the space is often done through the use of a logical volume manager. .SH "EXAMPLES" Understanding xfs_info output. .PP Suppose one has the following "xfs_info /dev/sda" output: .PP .RS 2 .Vb \&meta-data=/dev/sda isize=256 agcount=32, agsize=16777184 blks \& = sectsz=512 attr=2 \&data = bsize=4096 blocks=536869888, imaxpct=5 \& = sunit=32 swidth=128 blks \&naming =version 2 bsize=4096 \&log =internal bsize=4096 blocks=32768, version=2 \& = sectsz=512 sunit=32 blks, lazy-count=1 \&realtime =none extsz=524288 blocks=0, rtextents=0 .Ve .RE .PP Here, the data section of the output indicates "bsize=4096", meaning the data block size for this filesystem is 4096 bytes. This section also shows "sunit=32 swidth=128 blks", which means the stripe unit is 32*4096 bytes = 128 kibibytes and the stripe width is 128*4096 bytes = 512 kibibytes. A single stripe of this filesystem therefore consists of four stripe units (128 blocks / 32 blocks per unit). .SH SEE ALSO .BR mkfs.xfs (8), .BR md (4), .BR lvm (8), .BR mount (8). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_io.80000664000000000000000000004771012625713772015643 0ustar .TH xfs_io 8 .SH NAME xfs_io \- debug the I/O path of an XFS filesystem .SH SYNOPSIS .B xfs_io [ .B \-adfmrRstxT ] [ .B \-c .I cmd ] ...

The commands are run in the sequence given, then the program exits. .TP .BI \-p " prog" Set the program name for prompts and some error messages, the default value is .BR xfs_io . .TP .B \-f Create .I file if it does not already exist. .TP .B \-r Open .I file read-only, initially. This is required if .I file is immutable or append-only. .TP .B \-x Expert mode. Dangerous commands are only available in this mode. These commands also tend to require additional privileges. .TP .B \-V Prints the version number and exits. .PP The other .BR open (2) options described below are also available from the command line. .SH CONCEPTS .B xfs_io maintains a number of open files and memory mappings. Files can be initially opened on the command line (optionally), and additional files can also be opened later. .PP .B xfs_io commands can be broken up into three groups. Some commands are aimed at doing regular file I/O - read, write, sync, space preallocation, etc. .PP The second set of commands exist for manipulating memory mapped regions of a file - mapping, accessing, storing, unmapping, flushing, etc. .PP The remaining commands are for the navigation and display of data structures relating to the open files, mappings, and the filesystems where they reside. .PP Many commands have extensive online help. Use the .B help command for more details on any command. .SH FILE I/O COMMANDS .TP .BI "file [ " N " ]" Display a list of all open files and (optionally) switch to an alternate current open file. .TP .BI "open [[ \-acdfrstRT ] " path " ]" Closes the current file, and opens the file specified by .I path instead.

The .I device argument is the pathname of the partition or logical volume containing the filesystem. The .I device can be a regular file if the .B \-f option is used. The contents of the filesystem remain undisturbed. There are two major modes of operation in .BR xfs_logprint . .PP One mode is better for filesystem operation debugging. It is called the transactional view and is enabled through the .B \-t option. The transactional view prints only the portion of the log that pertains to recovery. In other words, it prints out complete transactions between the tail and the head. This view tries to display each transaction without regard to how they are split across log records. .PP The second mode starts printing out information from the beginning of the log. Some error blocks might print out in the beginning because the last log record usually overlaps the oldest log record. A message is printed when the physical end of the log is reached and when the logical end of the log is reached. A log record view is displayed one record at a time. Transactions that span log records may not be decoded fully. .SH OPTIONS .TP .B \-b Extract and print buffer information.

Normally, .B xfs_logprint tries to continue and unwind from bad logs. However, sometimes it just dies in bad ways. Using this option prevents core dumps. .TP .B \-f Specifies that the filesystem image to be processed is stored in a regular file at .I device (see the .BR mkfs.xfs "(8) " -d .I file option).

The .I source argument must be the pathname of the device or file containing the XFS filesystem and the .I target argument specifies the destination file name. If .I target is \-, then the output is sent to stdout. This allows the output to be redirected to another program such as a compression application. .PP .B xfs_metadump may only be used to copy unmounted filesystems, or read-only mounted filesystems. .PP .B xfs_metadump does not alter the source filesystem in any way. The .I target image is a contiguous (non-sparse) file containing all the filesystem's metadata and indexes to where the blocks were copied from. .PP By default, .B xfs_metadump obfuscates most file (regular file, directory and symbolic link) names and extended attribute names to allow the dumps to be sent without revealing confidential information. Extended attribute values are zeroed and no data is copied. The only exceptions are file or attribute names that are 4 or less characters in length. Also file names that span extents (this can only occur with the .BR mkfs.xfs (8) options where .B \-n .I size > .B \-b .IR size ) are not obfuscated. Names between 5 and 8 characters in length inclusively are partially obfuscated. .PP .B xfs_metadump should not be used for any purposes other than for debugging and reporting filesystem problems. The most common usage scenario for this tool is when .BR xfs_repair (8) fails to repair a filesystem and a metadump image can be sent for analysis. .PP The file generated by .B xfs_metadump can be restored to filesystem image (minus the data) using the .BR xfs_mdrestore (8) tool. .PP .SH OPTIONS .TP .B \-a Copies entire metadata blocks. Normally, .B xfs_metadump will zero any stale bytes interspersed with in-use metadata. Use this option to copy full metadata blocks, to provide more debugging information for a corrupted filesystem. Note that the extra data will be unobfuscated. .TP .B \-e Stops the dump on a read error. Normally, it will ignore read errors and copy all the metadata that is accessible. .TP .B \-f Specifies that the filesystem image to be processed is stored in a regular file (see the .B mkfs.xfs -d file option). This can also happen if an image copy of a filesystem has been made into an ordinary file with .BR xfs_copy (8). .TP .B \-F Specifies that we want to continue even if the superblock magic is not correct. If the source is truly not an XFS filesystem, the resulting image will be useless, and xfs_metadump may crash. .TP .B \-g Shows dump progress. This is sent to stdout if the .I target is a file or to stderr if the .I target is stdout. .TP .BI \-l " logdev" For filesystems which use an external log, this specifies the device where the external log resides. The external log is not copied, only internal logs are copied. .TP .B \-m Set the maximum size of an allowed metadata extent. Extremely large metadata extents are likely to be corrupt, and will be skipped if they exceed this value. The default size is 1000 blocks. .TP .B \-o Disables obfuscation of file names and extended attributes. .TP .B \-w Prints warnings of inconsistent metadata encountered to stderr.

Multiple .B \-c arguments may be given. The commands are run in the sequence given, then the program exits. .TP .BI \-p " prog" Set the program name for prompts and some error messages, the default value is .BR xfs_quota . .TP .B \-x Enable expert mode. All of the administrative commands (see the ADMINISTRATOR COMMANDS section below) which allow modifications to the quota system are available only in expert mode. .TP .BI \-d " project" Project names or numeric identifiers may be specified with this option, which restricts the output of the individual .B xfs_quota commands to the set of projects specified. Multiple .B \-d arguments may be given. .TP .B \-V Prints the version number and exits. .PP The optional .I path argument(s) can be used to specify mount points or device files which identify XFS filesystems. The output of the individual .B xfs_quota commands will then be restricted to the set of filesystems specified. .PP This manual page is divided into two sections \- firstly, information for users of filesystems with quota enabled, and the .B xfs_quota commands of interest to such users; and then information which is useful only to administrators of XFS filesystems using quota and the quota commands which allow modifications to the quota system. .PP Note that common to almost all of the individual commands described below are the options for specifying which quota types are of interest \- user quota .RB ( \-u ), group quota .RB ( \-g ), and/or project quota .RB ( \-p ). Also, several commands provide options to operate on "blocks used" .RB ( \-b ), "inodes used" .RB ( \-i ), and/or "realtime blocks used" .RB ( \-r ). .PP Many commands also have extensive online help. Use the .B help command for more details on any command. .SH QUOTA OVERVIEW .PP In most computing environments, disk space is not infinite. The quota subsystem provides a mechanism to control usage of disk space. Quotas can be set for each individual user on any/all of the local filesystems. The quota subsystem warns users when they exceed their allotted limit, but allows some extra space for current work (hard limit/soft limit). In addition, XFS filesystems with limit enforcement turned off can be used as an effective disk usage accounting system. .SS Users' View of Disk Quotas To most users, disk quotas are either of no concern or a fact of life that cannot be avoided. There are two possible quotas that can be imposed \- a limit can be set on the amount of space a user can occupy, and there may be a limit on the number of files (inodes) he can own. .PP The .B quota command provides information on the quotas that have been set by the system administrators and current usage. .PP There are four numbers for each limit: current usage, soft limit (quota), hard limit, and time limit. The soft limit is the number of 1K-blocks (or files) that the user is expected to remain below. The hard limit cannot be exceeded. If a user's usage reaches the hard limit, further requests for space (or attempts to create a file) fail with the "Quota exceeded" (EDQUOT) error. .PP When a user exceeds the soft limit, the timer is enabled. Any time the quota drops below the soft limits, the timer is disabled. If the timer pops, the particular limit that has been exceeded is treated as if the hard limit has been reached, and no more resources are allocated to the user. The only way to reset this condition, short of turning off limit enforcement or increasing the limit, is to reduce usage below quota. Only the superuser (i.e. a sufficiently capable process) can set the time limits and this is done on a per filesystem basis. .SS Surviving When the Quota Limit Is Reached In most cases, the only way for a user to recover from over-quota conditions is to abort whatever activity is in progress on the filesystem that has reached its limit, remove sufficient files to bring the limit back below quota, and retry the failed program. .br However, if a user is in the editor and a write fails because of an over quota situation, that is not a suitable course of action. It is most likely that initially attempting to write the file has truncated its previous contents, so if the editor is aborted without correctly writing the file, not only are the recent changes lost, but possibly much, or even all, of the contents that previously existed. .br There are several possible safe exits for a user caught in this situation. He can use the editor shell escape command to examine his file space and remove surplus files. Alternatively, using .BR sh (1), he can suspend the editor, remove some files, then resume it. A third possibility is to write the file to some other filesystem (perhaps to a file on .IR /tmp ) where the user's quota has not been exceeded. Then after rectifying the quota situation, the file can be moved back to the filesystem it belongs on. .SH USER COMMANDS .TP .B print Lists all paths with devices/project identifiers. The path list can come from several places \- the command line, the mount table, and the .I /etc/projects file. .TP .B df See the .B free command. .HP .B quota [ .B \-gpu ] [ .B \-bir ] [ .B \-hnNv ] [ .B \-f .I file ] [ .I ID | .I name ] ... .br Show individual usage and limits, for a single user .I name or numeric user .IR ID . The .B \-h option reports in a "human-readable" format similar to the .BR df (1) command. The .B \-n option reports the numeric IDs rather than the name. The .B \-N option omits the header. The .B \-v option outputs verbose information. The .B \-f option sends the output to .I file instead of stdout. .HP .B free [ .B \-bir ] [ .B \-hN ] [ .B \-f .I file ] .br Reports filesystem usage, much like the .BR df (1) utility. It can show usage for .BR b locks, .BR i node, and/or .BR r ealtime block space, and shows used, free, and total available. If project quota are in use (see the DIRECTORY TREE QUOTA section below), it will also report utilisation for those projects (directory trees). The .B \-h option reports in a "human-readable" format.

The .B \-f option outputs the report to .I file instead of stdout. .HP .B help [ .I command ] .br Online help for all commands, or one specific .IR command . .TP .B quit Exit .BR xfs_quota . .TP .B q See the .B quit command. .SH QUOTA ADMINISTRATION The XFS quota system differs to that of other filesystems in a number of ways. Most importantly, XFS considers quota information as filesystem metadata and uses journaling to provide a higher level guarantee of consistency. As such, it is administered differently, in particular: .IP 1. The .B quotacheck command has no effect on XFS filesystems. The first time quota accounting is turned on (at mount time), XFS does an automatic quotacheck internally; afterwards, the quota system will always be completely consistent until quotas are manually turned off. .IP 2. There is no need for quota file(s) in the root of the XFS filesystem. .IP 3. XFS distinguishes between quota accounting and limit enforcement. Quota accounting must be turned on at the time of mounting the XFS filesystem. However, it is possible to turn on/off limit enforcement any time quota accounting is turned on. The "quota" option to the .B mount command turns on both (user) quota accounting and enforcement. The "uqnoenforce" option must be used to turn on user accounting with limit enforcement disabled. .IP 4. Turning on quotas on the root filesystem is slightly different from the above. For IRIX XFS, refer to .BR quotaon (1M). For Linux XFS, the quota mount flags must be passed in with the "rootflags=" boot parameter. .IP 5. It is useful to use the .B state to monitor the XFS quota subsystem at various stages \- it can be used to see if quotas are turned on, and also to monitor the space occupied by the quota system itself.. .IP 6. There is a mechanism built into .B xfsdump that allows quota limit information to be backed up for later restoration, should the need arise. .IP 7. Quota limits cannot be set before turning on quotas on. .IP 8. XFS filesystems keep quota accounting on the superuser (user ID zero), and the tool will display the superuser's usage information. However, limits are never enforced on the superuser (nor are they enforced for group and project ID zero). .IP 9. XFS filesystems perform quota accounting whether the user has quota limits or not. .IP 10. XFS supports the notion of project quota, which can be used to implement a form of directory tree quota (i.e. to restrict a directory tree to only being able to use up a component of the filesystems available space; or simply to keep track of the amount of space used, or number of inodes, within the tree). .SH ADMINISTRATOR COMMANDS .HP .B path [ .I N ] .br Lists all paths with devices/project identifiers or set the current path to the .IR N th list entry (the current path is used by many of the commands described here, it identifies the filesystem toward which a command is directed). The path list can come from several places \- the command line, the mount table, and the .I /etc/projects file. .HP .B report [ .B \-gpu ] [ .B \-bir ] [ .B \-ahntLNU ] [ .B \-f .I file ] .br Report filesystem quota information. This reports all quota usage for a filesystem, for the specified quota type .RB ( u / g / p and/or .BR b locks/ i nodes/ r ealtime). It reports blocks in 1KB units by default. The .B \-h option reports in a "human-readable" format similar to the .BR df (1) command. The .B \-f option outputs the report to .I file instead of stdout. The .B \-a option reports on all filesystems. The .B \-n option outputs the numeric ID instead of the name. The .B \-L and .B \-U options specify lower and upper ID bounds to report on. The .B \-N option reports information without the header line. The .B \-t option performs a terse report. .HP .B state [ .B \-gpu ] [ .B \-av ] [ .B \-f .I file ] .br Report overall quota state information. This reports on the state of quota accounting, quota enforcement, and the number of extents being used by quota metadata within the filesystem. The .B \-f option outputs state information to .I file instead of stdout. The .B \-a option reports state on all filesystems and not just the current path. .HP .B limit [ .B \-gpu ] .BI bsoft= N | .BI bhard= N | .BI isoft= N | .BI ihard= N | .BI rtbsoft= N | .BI rtbhard= N .B \-d | .I id | .I name .br Set quota block limits (bhard/bsoft), inode count limits (ihard/isoft) and/or realtime block limits (rtbhard/rtbsoft). The .B \-d option (defaults) can be used to set the default value that will be used, otherwise a specific .BR u ser/ g roup/ p roject .I name or numeric .IR id entifier must be specified. .HP .B timer [ .B \-gpu ] [ .B \-bir ] .I value .br Allows the quota enforcement timeout (i.e. the amount of time allowed to pass before the soft limits are enforced as the hard limits) to be modified. The current timeout setting can be displayed using the .B state command. The value argument is a number of seconds, but units of \&'minutes', 'hours', 'days', and 'weeks' are also understood (as are their abbreviations 'm', 'h', 'd', and 'w'). .HP .B warn [ .B \-gpu ] [ .B \-bir ] .I value .B -d | .I id | .I name .br Allows the quota warnings limit (i.e. the number of times a warning will be send to someone over quota) to be viewed and modified. The .B \-d option (defaults) can be used to set the default time that will be used, otherwise a specific .BR u ser/ g roup/ p roject .I name or numeric .IR id entifier must be specified. .B NOTE: this feature is not currently implemented. .TP .BR enable " [ " \-gpu " ] [ " \-v " ]" Switches on quota enforcement for the filesystem identified by the current path. This requires the filesystem to have been mounted with quota enabled, and for accounting to be currently active. The .B \-v option (verbose) displays the state after the operation has completed. .TP .BR disable " [ " \-gpu " ] [ " \-v " ]" Disables quota enforcement, while leaving quota accounting active. The .B \-v option (verbose) displays the state after the operation has completed. .TP .BR off " [ " \-gpu " ] [ " \-v " ]" Permanently switches quota off for the filesystem identified by the current path. Quota can only be switched back on subsequently by unmounting and then mounting again. .TP .BR remove " [ " \-gpu " ] [ " \-v " ]" Remove any space allocated to quota metadata from the filesystem identified by the current path. Quota must not be enabled on the filesystem, else this operation will report an error. .HP .B dump [ .B \-gpu ] [ .B \-f .I file ] .br Dump out quota limit information for backup utilities, either to standard output (default) or to a .IR file . This is only the limits, not the usage information, of course. .HP .B restore [ .B \-gpu ] [ .B \-f .I file ] .br Restore quota limits from a backup .IR file . The file must be in the format produced by the .B dump command. .HP .B quot [ .B \-gpu ] [ .B \-bir ] [ .B \-acnv ] [ .B \-f .I file ] .br Summarize filesystem ownership, by user, group or project. This command uses a special XFS "bulkstat" interface to quickly scan an entire filesystem and report usage information. This command can be used even when filesystem quota are not enabled, as it is a full-filesystem scan (it may also take a long time...). The .B \-a option displays information on all filesystems. The .B \-c option displays a histogram instead of a report. The .B \-n option displays numeric IDs rather than names. The .B \-v option displays verbose information. The .B \-f option send the output to .I file instead of stdout. .HP .B project [ .B \-cCs [ .B \-d .I depth ] [ .B \-p .I path ] .I id | .I name ] .br The .BR \-c , .BR \-C , and .B \-s options allow the directory tree quota mechanism to be maintained. .BR \-d allows to limit recursion level when processing project directories and .BR \-p allows to specify project paths at command line ( instead of .I /etc/projects ). All options are discussed in detail below. .SH DIRECTORY TREE QUOTA The project quota mechanism in XFS can be used to implement a form of directory tree quota, where a specified directory and all of the files and subdirectories below it (i.e. a tree) can be restricted to using a subset of the available space in the filesystem. .PP A managed tree must be setup initially using the .B \-s option to the .B project command. The specified project name or identifier is matched to one or more trees defined in .IR /etc/projects , and these trees are then recursively descended to mark the affected inodes as being part of that tree. This process sets an inode flag and the project identifier on every file in the affected tree. Once this has been done, new files created in the tree will automatically be accounted to the tree based on their project identifier. An attempt to create a hard link to a file in the tree will only succeed if the project identifier matches the project identifier for the tree. The .B xfs_io utility can be used to set the project ID for an arbitrary file, but this can only be done by a privileged user. .PP A previously setup tree can be cleared from project quota control through use of the .B project \-C option, which will recursively descend the tree, clearing the affected inodes from project quota control. .PP Finally, the .B project \-c option can be used to check whether a tree is setup, it reports nothing if the tree is correct, otherwise it reports the paths of inodes which do not have the project ID of the rest of the tree, or if the inode flag is not set. .PP Option .B \-d can be used to limit recursion level (\-1 is infinite, 0 is top level only, 1 is first level ... ). Option .B \-p adds possibility to specify project paths in command line without a need for .I /etc/projects to exist. Note that if projects file exists then it is also used. .SH EXAMPLES Enabling quota enforcement on an XFS filesystem (restrict a user to a set amount of space). .nf .sp .in +5 # mount \-o uquota /dev/xvm/home /home # xfs_quota \-x \-c 'limit bsoft=500m bhard=550m tanya' /home # xfs_quota \-x \-c report /home .in -5 .fi .PP Enabling project quota on an XFS filesystem (restrict files in log file directories to only using 1 gigabyte of space). .nf .sp .in +5 # mount \-o prjquota /dev/xvm/var /var # echo 42:/var/log >> /etc/projects # echo logfiles:42 >> /etc/projid # xfs_quota \-x \-c 'project \-s logfiles' /var # xfs_quota \-x \-c 'limit \-p bhard=1g logfiles' /var .in -5 .fi .PP Same as above without a need for configuration files. .nf .sp .in +5 # rm \-f /etc/projects /etc/projid # mount \-o prjquota /dev/xvm/var /var # xfs_quota \-x \-c 'project \-s \-p /var/log 42' /var # xfs_quota \-x \-c 'limit \-p bhard=1g 42' /var .in -5 .fi .SH CAVEATS XFS implements delayed allocation (aka. allocate-on-flush) and this has implications for the quota subsystem. Since quota accounting can only be done when blocks are actually allocated, it is possible to issue (buffered) writes into a file and not see the usage immediately updated. Only when the data is actually written out, either via one of the kernels flushing mechanisms, or via a manual .BR sync (2), will the usage reported reflect what has actually been written. .PP In addition, the XFS allocation mechanism will always reserve the maximum amount of space required before proceeding with an allocation. If insufficient space for this reservation is available, due to the block quota limit being reached for example, this may result in the allocation failing even though there is sufficient space. Quota enforcement can thus sometimes happen in situations where the user is under quota and the end result of some operation would still have left the user under quota had the operation been allowed to run its course. This additional overhead is typically in the range of tens of blocks. .PP Both of these properties are unavoidable side effects of the way XFS operates, so should be kept in mind when assigning block limits. .SH BUGS Quota support for filesystems with realtime subvolumes is not yet implemented, nor is the quota warning mechanism (the Linux .BR warnquota (8) tool can be used to provide similar functionality on that platform). .SH FILES .PD 0 .TP 20 .I /etc/projects Mapping of numeric project identifiers to directories trees. .TP .I /etc/projid Mapping of numeric project identifiers to project names. .PD .SH IRIX SEE ALSO .BR quotaon (1M), .BR xfs (4). .SH LINUX SEE ALSO .BR warnquota (8), .BR xfs (5). .SH SEE ALSO .BR df (1), .BR mount (1), .BR sync (2), .BR projid (5), .BR projects (5). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_repair.80000664000000000000000000003654312625713772016520 0ustar .TH xfs_repair 8 .SH NAME xfs_repair \- repair an XFS filesystem .SH SYNOPSIS .B xfs_repair [ .B \-dfLnPv ] [ .B \-m .I maxmem ] [ .BI \-c " subopt" = value ] [ .B \-o .I subopt\c [\c .B =\c .IR value ] ] [ .B \-t .I interval ] [ .B \-l .I logdev ] [ .B \-r .I rtdev ] .I device .br .B xfs_repair \-V .SH DESCRIPTION .B xfs_repair repairs corrupt or damaged XFS filesystems (see .BR xfs (5)). The filesystem is specified using the .I device argument which should be the device name of the disk partition or volume containing the filesystem. If given the name of a block device, .B xfs_repair will attempt to find the raw device associated with the specified block device and will use the raw device instead. .PP Regardless, the filesystem to be repaired must be unmounted, otherwise, the resulting filesystem may be inconsistent or corrupt. .SH OPTIONS .TP .B \-f Specifies that the filesystem image to be processed is stored in a regular file at .I device (see the .B mkfs.xfs \-d .I file option). This might happen if an image copy of a filesystem has been copied or written into an ordinary file. This option implies that any external log or realtime section is also in an ordinary file. .TP .B \-L Force Log Zeroing. Forces .B xfs_repair to zero the log even if it is dirty (contains metadata changes). When using this option the filesystem will likely appear to be corrupt, and can cause the loss of user files and/or data. .TP .BI \-l " logdev" Specifies the device special file where the filesystem's external log resides. Only for those filesystems which use an external log. See the .B mkfs.xfs \-l option, and refer to .BR xfs (5) for a detailed description of the XFS log. .TP .BI \-r " rtdev" Specifies the device special file where the filesystem's realtime section resides. Only for those filesystems which use a realtime section. See the .B mkfs.xfs \-r option, and refer to .BR xfs (5) for a detailed description of the XFS realtime section. .TP .B \-n No modify mode. Specifies that .B xfs_repair should not modify the filesystem but should only scan the filesystem and indicate what repairs would have been made. .TP .B \-P Disable prefetching of inode and directory blocks. Use this option if you find .B xfs_repair gets stuck and stops proceeding. Interrupting a stuck .B xfs_repair is safe. .TP .BI \-m " maxmem" Specifies the approximate maximum amount of memory, in megabytes, to use for .BR xfs_repair . .B xfs_repair has its own internal block cache which will scale out up to the lesser of the process's virtual address limit or about 75% of the system's physical RAM. This option overrides these limits. .IP .B NOTE: These memory limits are only approximate and may use more than the specified limit. .TP .BI \-c " subopt" = value Change filesystem parameters. Refer to .BR xfs_admin (8) for information on changing filesystem parameters. .HP .B \-o .I subopt\c [\c .B =\c .IR value ] .br Override what the program might conclude about the filesystem if left to its own devices. .IP The .IR subopt ions supported are: .RS 1.0i .TP .BI bhash= bhashsize overrides the default buffer cache hash size. The total number of buffer cache entries are limited to 8 times this amount. The default size is set to use up the remainder of 75% of the system's physical RAM size. .TP .BI ag_stride= ags_per_concat_unit This creates additional processing threads to parallel process AGs that span multiple concat units. This can significantly reduce repair times on concat based filesystems. .TP .BI force_geometry Check the filesystem even if geometry information could not be validated. Geometry information can not be validated if only a single allocation group exists and thus we do not have a backup superblock available, or if there are two allocation groups and the two superblocks do not agree on the filesystem geometry. Only use this option if you validated the geometry yourself and know what you are doing. If In doubt run in no modify mode first. .RE .TP .B \-t " interval" Modify reporting interval, specified in seconds. During long runs .B xfs_repair outputs its progress every 15 minutes. Reporting is only activated when ag_stride is enabled. .TP .B \-v Verbose output. May be specified multiple times to increase verbosity. .TP .B \-d Repair dangerously. Allow .B xfs_repair to repair an XFS filesystem mounted read only. This is typically done on a root filesystem from single user mode, immediately followed by a reboot. .TP .B \-V Prints the version number and exits. .SS Checks Performed Inconsistencies corrected include the following: .IP 1. Inode and inode blockmap (addressing) checks: bad magic number in inode, bad magic numbers in inode blockmap blocks, extents out of order, incorrect number of records in inode blockmap blocks, blocks claimed that are not in a legal data area of the filesystem, blocks that are claimed by more than one inode. .IP 2. Inode allocation map checks: bad magic number in inode map blocks, inode state as indicated by map (free or in-use) inconsistent with state indicated by the inode, inodes referenced by the filesystem that do not appear in the inode allocation map, inode allocation map referencing blocks that do not appear to contain inodes. .IP 3. Size checks: number of blocks claimed by inode inconsistent with inode size, directory size not block aligned, inode size not consistent with inode format. .IP 4. Directory checks: bad magic numbers in directory blocks, incorrect number of entries in a directory block, bad freespace information in a directory leaf block, entry pointing to an unallocated (free) or out of range inode, overlapping entries, missing or incorrect dot and dotdot entries, entries out of hashvalue order, incorrect internal directory pointers, directory type not consistent with inode format and size. .IP 5. Pathname checks: files or directories not referenced by a pathname starting from the filesystem root, illegal pathname components. .IP 6. Link count checks: link counts that do not agree with the number of directory references to the inode. .IP 7. Freemap checks: blocks claimed free by the freemap but also claimed by an inode, blocks unclaimed by any inode but not appearing in the freemap. .IP 8. Super Block checks: total free block and/or free i-node count incorrect, filesystem geometry inconsistent, secondary and primary superblocks contradictory. .PP Orphaned files and directories (allocated, in-use but unreferenced) are reconnected by placing them in the .I lost+found directory. The name assigned is the inode number. .SS Disk Errors .B xfs_repair aborts on most disk I/O errors. Therefore, if you are trying to repair a filesystem that was damaged due to a disk drive failure, steps should be taken to ensure that all blocks in the filesystem are readable and writable before attempting to use .B xfs_repair to repair the filesystem. A possible method is using .BR dd (8) to copy the data onto a good disk. .SS lost+found The directory .I lost+found does not have to already exist in the filesystem being repaired. If the directory does not exist, it is automatically created if required. If it already exists, it will be checked for consistency and if valid will be used for additional orphaned files. Invalid .I lost+found directories are removed and recreated. Existing files in a valid .I lost+found are not removed or renamed. .SS Corrupted Superblocks XFS has both primary and secondary superblocks. .B xfs_repair uses information in the primary superblock to automatically find and validate the primary superblock against the secondary superblocks before proceeding. Should the primary be too corrupted to be useful in locating the secondary superblocks, the program scans the filesystem until it finds and validates some secondary superblocks. At that point, it generates a primary superblock. .SS Quotas If quotas are in use, it is possible that .B xfs_repair will clear some or all of the filesystem quota information. If so, the program issues a warning just before it terminates. If all quota information is lost, quotas are disabled and the program issues a warning to that effect. .PP Note that .B xfs_repair does not check the validity of quota limits. It is recommended that you check the quota limit information manually after .BR xfs_repair . Also, space usage information is automatically regenerated the next time the filesystem is mounted with quotas turned on, so the next quota mount of the filesystem may take some time. .SH DIAGNOSTICS .B xfs_repair issues informative messages as it proceeds indicating what it has found that is abnormal or any corrective action that it has taken. Most of the messages are completely understandable only to those who are knowledgeable about the structure of the filesystem. Some of the more common messages are explained here. Note that the language of the messages is slightly different if .B xfs_repair is run in no-modify mode because the program is not changing anything on disk. No-modify mode indicates what it would do to repair the filesystem if run without the no-modify flag. .PP .B disconnected inode .IB ino , .B moving to lost+found .IP An inode numbered .I ino was not connected to the filesystem directory tree and was reconnected to the .I lost+found directory. The inode is assigned the name of its inode number .RI ( ino ). If a .I lost+found directory does not exist, it is automatically created. .PP .B disconnected dir inode .IB ino , .B moving to lost+found .IP As above only the inode is a directory inode. If a directory inode is attached to .IR lost+found , all of its children (if any) stay attached to the directory and therefore get automatically reconnected when the directory is reconnected. .PP .B imap claims in-use inode .I ino .B is free, correcting imap .IP The inode allocation map thinks that inode .I ino is free whereas examination of the inode indicates that the inode may be in use (although it may be disconnected). The program updates the inode allocation map. .PP .B imap claims free inode .I ino .B is in use, correcting imap .IP The inode allocation map thinks that inode .I ino is in use whereas examination of the inode indicates that the inode is not in use and therefore is free. The program updates the inode allocation map. .PP .B resetting inode .I ino .B nlinks from .I x .B to .I y .IP The program detected a mismatch between the number of valid directory entries referencing inode .I ino and the number of references recorded in the inode and corrected the the number in the inode. .PP .I fork-type .B fork in ino .I ino .B claims used block .I bno .IP Inode .I ino claims a block .I bno that is used (claimed) by either another inode or the filesystem itself for metadata storage. The .I fork-type is either .B data or .B attr indicating whether the problem lies in the portion of the inode that tracks regular data or the portion of the inode that stores XFS attributes. If the inode is a real-time (rt) inode, the message says so. Any inode that claims blocks used by the filesystem is deleted. If two or more inodes claim the same block, they are both deleted. .PP .I fork-type .B fork in ino .I ino .B claims dup extent ... .IP Inode .I ino claims a block in an extent known to be claimed more than once. The offset in the inode, start and length of the extent is given. The message is slightly different if the inode is a real-time (rt) inode and the extent is therefore a real-time (rt) extent. .PP .B inode .I ino .B \- bad extent ... .IP An extent record in the blockmap of inode .I ino claims blocks that are out of the legal range of the filesystem. The message supplies the start, end, and file offset of the extent. The message is slightly different if the extent is a real-time (rt) extent. .PP .B bad .I fork-type .B fork in inode .I ino .IP There was something structurally wrong or inconsistent with the data structures that map offsets to filesystem blocks. .PP .B cleared inode .I ino .IP There was something wrong with the inode that was uncorrectable so the program freed the inode. This usually happens because the inode claims blocks that are used by something else or the inode itself is badly corrupted. Typically, this message is preceded by one or more messages indicating why the inode needed to be cleared. .PP .B bad attribute fork in inode .IR ino , .B clearing attr fork .IP There was something wrong with the portion of the inode that stores XFS attributes (the attribute fork) so the program reset the attribute fork. As a result of this, all attributes on that inode are lost. .PP .B correcting nextents for inode .IR ino , .B was .I x .B \- counted .I y .IP The program found that the number of extents used to store the data in the inode is wrong and corrected the number. The message refers to nextents if the count is wrong on the number of extents used to store attribute information. .PP .B entry .I name .B in dir .I dir_ino .B not consistent with .. value .BI ( xxxx ) .B in dir ino .IB ino , .B junking entry .I name .B in directory inode .I dir_ino .IP The entry .I name in directory inode .I dir_ino references a directory inode .IR ino . However, the ..\& entry in directory .I ino does not point back to directory .IR dir_ino , so the program deletes the entry .I name in directory inode .IR dir_ino . If the directory inode .I ino winds up becoming a disconnected inode as a result of this, it is moved to .I lost+found later. .PP .B entry .I name .B in dir .I dir_ino .B references already connected dir ino .IB ino , .B junking entry .I name .B in directory inode .I dir_ino .IP The entry .I name in directory inode .I dir_ino points to a directory inode .I ino that is known to be a child of another directory. Therefore, the entry is invalid and is deleted. This message refers to an entry in a small directory. If this were a large directory, the last phrase would read "will clear entry". .PP .B entry references free inode .I ino .B in directory .IB dir_ino , .B will clear entry .IP An entry in directory inode .I dir_ino references an inode .I ino that is known to be free. The entry is therefore invalid and is deleted. This message refers to a large directory. If the directory were small, the message would read "junking entry ...". .SH EXIT STATUS .B xfs_repair \-n (no modify node) will return a status of 1 if filesystem corruption was detected and 0 if no filesystem corruption was detected. .B xfs_repair run without the \-n option will always return a status code of 0. .SH BUGS The filesystem to be checked and repaired must have been unmounted cleanly using normal system administration procedures (the .BR umount (8) command or system shutdown), not as a result of a crash or system reset. If the filesystem has not been unmounted cleanly, mount it and unmount it cleanly before running .BR xfs_repair . .PP .B xfs_repair does not do a thorough job on XFS extended attributes. The structure of the attribute fork will be consistent, but only the contents of attribute forks that will fit into an inode are checked. This limitation will be fixed in the future. .PP The no-modify mode .RB ( \-n option) is not completely accurate. It does not catch inconsistencies in the freespace and inode maps, particularly lost blocks or subtly corrupted maps (trees). .PP The no-modify mode can generate repeated warnings about the same problems because it cannot fix the problems as they are encountered. .PP If a filesystem fails to be repaired, a metadump image can be generated with .BR xfs_metadump (8) and be sent to an XFS maintainer to be analysed and .B xfs_repair fixed and/or improved. .SH SEE ALSO .BR dd (1), .BR mkfs.xfs (8), .BR umount (8), .BR xfs_admin (8), .BR xfs_metadump (8), .BR xfs (5). xfsprogs-4.3.0+nmu1ubuntu1.1/man/man8/xfs_rtcp.80000664000000000000000000000230712560572026016166 0ustar .TH xfs_rtcp 8 .SH NAME xfs_rtcp \- XFS realtime copy command .SH SYNOPSIS .B xfs_rtcp [ .B \-e .I extsize ] [ .B -p ] .IR source " ... " target .br .B xfs_rtcp \-V .SH DESCRIPTION .B xfs_rtcp copies a file to the realtime partition on an XFS filesystem. If there is more than one .I source and .IR target , the final argument (the .IR target ) must be a directory which already exists. .SH OPTIONS .TP .BI \-e " extsize" Sets the extent size of the destination realtime file. .TP .B \-p Use if the size of the source file is not an even multiple of the block size of the destination filesystem. When .B \-p is specified .B xfs_rtcp will pad the destination file to a size which is an even multiple of the filesystem block size. This is necessary since the realtime file is created using direct I/O and the minimum I/O is the filesystem block size. .TP .B \-V Prints the version number and exits. .SH SEE ALSO .BR xfs (5), .BR mkfs.xfs (8), .BR mount (8). .SH CAVEATS Currently, realtime partitions are not supported under the Linux version of XFS, and use of a realtime partition .B WILL CAUSE CORRUPTION on the data partition. As such, this command is made available for curious .B DEVELOPERS ONLY at this point in time. xfsprogs-4.3.0+nmu1ubuntu1.1/mdrestore/0000775000000000000000000000000012625722130014624 5ustar xfsprogs-4.3.0+nmu1ubuntu1.1/mdrestore/Makefile0000664000000000000000000000071312560572026016272 0ustar # # Copyright (c) 2007 Silicon Graphics, Inc.

The basic algorithm. TODO: (D == DONE) 0) Need to bring some sanity into the case of flags that can be set in the secondaries at mkfs time but reset or cleared in the primary later in the filesystem's life. 0) Clear the persistent read-only bit if set. Clear the shared bit if set and the version number is zero. This brings the filesystem back to a known state. 0) make sure that superblock geometry code checks the logstart value against whether or not we have an internal log. If we have an internal log and a logdev, that's ok. (Maybe we just aren't using it). If we have an external log (logstart == 0) but no logdev, that's right out. 0) write secondary superblock search code. Rewrite initial superblock parsing code to be less complicated. Just use variables to indicate primary, secondary, etc., and use a function to get the SB given a specific location or something. 2) For inode alignment, if the SB bit is set and the inode alignment size field in the SB is set, then believe that the fs inodes MUST be aligned and disallow any non-aligned inodes. Likewise, if the SB bit isn't set (or earlier version) and the inode alignment size field is zero, then never set the bit even if the inodes are aligned. Note that the bits and alignment values are replicated in the secondary superblocks. 0) add feature specification options to parse_arguments 0) add logic to add_inode_ref(), add_inode_reached() to detect nlink overflows in cases where the fs (or user had indicated fs) doesn't support new nlinks. 6) check to make sure that the inodes containing btree blocks with # recs < minrecs aren't legit -- e.g. the only descendant of a root block. 7) inode di_size value sanity checking -- should always be less than the biggest filebno offset mentioned in the bmaps. Doesn't have to be equal though since we're allowed to overallocate (it just wastes a little space). This is for both regular files and directories (have to modify the existing directory check). Add tracking of largest offset in bmap scanning code. Compare value against di_size. Should be >= di_size. Alternatively, you could pass the inode into down through the extent record processing layer and make the checks there. Add knowledge of quota inodes. size of quota inode is always zero. We should maintain that. 8) Basic quota stuff. Invariants if quota feature bit is set, the quota inodes if set, should point to disconnected, 0 len inodes. D - if quota inodes exist, the quota bits must be turned on. It's ok for the quota flags to be zeroed but they should be in a legal state (see xfs_quota.h). D - if the quota flags are non-zero, the corresponding quota inodes must exist. quota inodes are never deleted, only their space is freed. if quotas are being downgraded, then check quota inodes at the end of phase 3. If they haven't been cleared yet, clear them. Regardless, then clear sb flags (quota inode fields, quota flags, and quota bit). 5) look at verify_inode_chunk(). it's probably really broken. 9) Complicated quota stuff. Add code to bmap scan code to track used blocks. Add another pair of AVL trees to track user and project quota limits. Set AVL trees up at the beginning of phase 3. Quota inodes can be rebuilt or corrected later if damaged. D - 0) fix directory processing. phase 3, if an entry references a free inode, *don't* mark it used. wait for the rest of phase 3 processing to hit that inode. If it looks like it's in use, we'll mark in use then. If not, we'll clear it and mark the inode map. then in phase 4, you can depend on the inode map. should probably set the parent info in phase 4. So we have a check_dups flag. Maybe we should change the name of check_dir to discover_inodes. During phase 3 (discover_inodes == 1), uncertain inodes are added to list. During phase 4 (discover_inodes == 0), they aren't. And we never mark inodes in use from the directory code. During phase 4, we shouldn't complain about names with a leading '/' since we made those names in phase 3. Have to change dino_chunks.c (parent setting), dinode.c and dir.c. D - 0) make sure we don't screw up filesystems with real-time inodes. remember to initialize real-time map with all blocks XR_E_FREE. D - 4) check contents of symlinks as well as lengths in process_symlinks() in dinode.c. Right now, we only check lengths. D - 1) Feature mismatches -- for quotas and attributes, if the stuff exists in the filesystem, set the superblock version bits. D - 0) rewrite directory leaf block holemap comparison code. probably should just check the leaf block hole info against our incore bitmap. If the hole flag is not set, then we know that there can only be one hole and it has to be between the entry table and the top of heap. If the hole flag is set, then it's ok if the on-disk holemap doesn't describe everything as long as what it does describe doesn't conflict with reality. D - 0) rewrite setting nlinks handling -- for version 1 inodes, set both nlinks and onlinks (zero projid_lo/hi and pad) if we have to change anything. For version 2, I think we're ok. D - 0) Put awareness of quota inode into mark_standalone_inodes. D - 8) redo handling of superblocks with bad version numbers. need to bail out (without harming) fs's that have sbs that are newer than we are. D - 0) How do we handle feature mismatches between fs and superblock? For nlink, check each inode after you know it's good. If onlinks is 0 and nlinks is > 0 and it's a version 2 inode, then it really is a version 2 inode and the nlinks flag in the SB needs to be set. If it's a version 2 inode and the SB agrees but onlink is non-zero, then clear onlink. D - 3) keep cumulative counts of freeblocks, inodes, etc. to set in the superblock at the end of phase 5. Remember that agf freeblock counters don't include blocks used by the non-root levels of the freespace trees but that the sb free block counters include those. D - 0) Do parent setting in directory code (called by phase 3). actually, I put it in process_inode_set and propagated the parent up to it from the process_dinode/process_dir routines. seemed cleaner than pushing the irec down and letting them bang on it. D - 0) If we clear a file in phase 4, make sure that if it's a directory that the parent info is cleared also. D - 0) put inode tree flashover (call to add_ino_backptrs) into phase 5. D - 0) do set/get_inode_parent functions in incore_ino.c. also do is/set/ inode_processed. D - 0) do a versions.c to extract feature info and set global vars from the superblock version number and possibly feature bits D - 0) change longform_dir_entry_check + shortform_dir_entry_check to return a count of how many illegal '/' entries exist. if > 0, then process_dirstack needs to call prune_dir_entry with a hash value of 0 to delete the entries. D - 0) add the "processed" bitfield to the backptrs_t struct that gets attached after phase 4. D- ) Phase 6 !!! D - 0) look at usage of XFS_MAKE_IPTR(). It does the right arithmetic assuming you count your offsets from the beginning of the buffer. D - 0) look at references to XFS_INODES_PER_CHUNK. change the ones that really mean sizeof(__uint64_t)*NBBY to something else (like that only defined as a constant INOS_PER_IREC. this isn't as important since XFS_INODES_PER_CHUNK will never chang D - 0) look at junk_zerolen_dir_leaf_entries() to make sure it isn't hosing the freemap since it assumed that bytes between the end of the table and firstused didn't show up in the freemap when they actually do. D - 0) track down XFS_INO_TO_OFFSET() usage. I don't think I'm using it right. (e.g. I think it gives you the offset of an inode into a block but on small block filesystems, I may be reading in inodes in multiblock buffers and working from the start of the buffer plus I'm using it to get offsets into my ino_rec's which may not be a good idea since I use 64-inode ino_rec's whereas the offset macro works off blocksize). D - 0.0) put buffer -> dirblock conversion macros into xfs kernel code D - 0.2) put in sibling pointer checking and path fixup into bmap (long form) scan routines in scan.c D - 0.3) find out if bmap btrees with only root blocks are legal. I'm betting that they're not because they'd be extent inodes instead. If that's the case, rip some code out of process_btinode() Algorithm (XXX means not done yet): Phase 1 -- get a superblock and zero log get a superblock -- either read in primary or find a secondary (ag header), check ag headers To find secondary: Go for brute force and read in the filesystem N meg at a time looking for a superblock. as a slight optimization, we could maybe skip ahead some number of blocks to try and get towards the end of the first ag. After you find a secondary, try and find at least other ags as a verification that the secondary is a good superblock. XXX - Ugh. Have to take growfs'ed filesystems into account. The root superblock geometry info may not be right if recovery hasn't run or it's been trashed. The old ag's may or may not be right since the system could have crashed during growfs or the bwrite() to the superblocks could have failed and the buffer been reused. So we need to check to see if another ag exists beyond the "last" ag to see if a growfs happened. If not, then we know that the geometry info is good and treat the fs as a non-growfs'ed fs. If we do have inconsistencies, then the smaller geometry is the old fs and the larger the new. We can check the new superblocks to see if they're good. If not, then we know the system crashed at or soon after the growfs and we can choose to either accept the new geometry info or trash it and truncate the fs back to the old geometry parameters. Cross-check geometry information in secondary sb's with primary to ensure that it's correct. Use sim code to allow mount filesystems *without* reading in root inode. This sets up the xfs_mount_t structure and allows us to use XFS_* macros that we wouldn't otherwise be able to use. Note, I split phase 1 and 2 into separate pieces because I want to initialize the xfs_repair incore data structures after phase 1. parse superblock version and feature flags and set appropriate global vars to reflect the flags (attributes, quotas, etc.) Workaround for the mkfs "not zeroing the superblock buffer" bug. Determine what field is the last valid non-zero field in the superblock. The trick here is to be able to differentiate the last valid non-zero field in the primary superblock and secondaries because they may not be the same. Fields in the primary can be set as the filesystem gets upgraded but the upgrades won't touch the secondaries. This means that we need to find some number of secondaries and check them. So we do the checking here and the setting in phase2. Phase 2 -- check integrity of allocation group allocation structures zero the log if in no modify mode sanity check ag headers -- superblocks match, agi isn't trashed -- the agf and agfl don't really matter because we can just recreate them later. Zero part of the superblock buffer if necessary Walk the freeblock trees to get an initial idea of what the fs thinks is free. Files that disagree (claim free'd blocks) can be salvaged or deleted. If the btree is internally inconsistent, when in doubt, mark blocks free. If they're used, they'll be stolen back later. don't have to check sibling pointers for each level since we're going to regenerate all the trees anyway. Walk the inode allocation trees and make sure they're ok, otherwise the sim inode routines will probably just barf. mark inode allocation tree blocks and ag header blocks as used blocks. If the trees are corrupted, this phase will generate "uncertain" inode chunks. Those chunks go on a list and will have to verified later. Record the blocks that are used to detect corruption and multiply claimed blocks. These trees will be regenerated later. Mark the blocks containing inodes referenced by uncorrupted inode trees as being used by inodes. The other blocks will get marked when/if the inodes are verified. calculate root and realtime inode numbers from the filesystem geometry, fix up mount structure's incore superblock if they're wrong. ASSUMPTION: at end of phase 2, we've got superblocks and ag headers that are not garbage (some data in them like counters and the freeblock and inode trees may be inconsistent but the header is readable and otherwise makes sense). XXX if in no_modify mode, check for blocks claimed by one freespace btree and not the other Phase 3 -- traverse inodes to make the inodes, bmaps and freespace maps consistent. For each ag, use either the incore inode map or scan the ag for inodes. Let's use the incore inode map, now that we've made one up in phase2. If we lose the maps, we'll locate inodes when we traverse the directory heirarchy. If we lose both, we could scan the disk. Ugh. Maybe make that a command-line option that we support later. ASSUMPTION: we know if the ag allocation btrees are intact (phase 2) First - Walk and clear the ag unlinked lists. We'll process the inodes later. Check and make sure that the unlinked lists reference known inodes. If not, add to the list of uncertain inodes. Second, check the uncertain inode list generated in phase2 and above and get them into the inode tree if they're good. The incore inode cluster tree *always* has good clusters (alignment, etc.) in it. Third, make sure that the root inode is known. If not, and we know the inode number from the superblock, discover that inode and its chunk. Then, walk the incore inode-cluster tree. Maintain an in-core bitmap over the entire fs for block allocation. traverse each inode, make sure inode mode field matches free/allocated bit in the incore inode allocation tree. If there's a mismatch, assume that the inode is in use. - for each in-use inode, traverse each bmap/dir/attribute map or tree. Maintain a map (extent list?) for the current inode. - For each block marked as used, check to see if already known (referenced by another file or directory) and sanity check the contents of the block as well if possible (in the case of meta-blocks). - if the inode claims already used blocks, mark the blocks as multiply claimed (duplicate) and go on. the inode will be cleared in phase 4. - if metablocks are garbaged, clear the inode after traversing what you can of the bmap and proceed to next inode. We don't have to worry about trashing the maps or trees in cleared inodes because the blocks will show up as free in the ag freespace trees that we set up in phase 5. - clear the di_next_unlinked pointer -- all unlinked but active files go bye-bye. - All blocks start out unknown. We need the last state in case we run into a case where we need to step on a block to store filesystem meta-data and it turns out later that it's referenced by some inode's bmap. In that case, the inode loses because we've already trashed the block. This shouldn't happen in the first version unless some inode has a bogus bmap referencing blocks in the ag header but the 4th state will keep us from inadvertently doing something stupid in that case. - If inode is allocated, mark all blocks allocated to the current inode as allocated in the incore freespace bitmap. - If inode is good and a directory, scan through it to find leaf entries and discover any unknown inodes. For shortform, we correct what we can. If the directory is corrupt, we try and fix it in place. If it has zero good entries, then we blast it. All unknown inodes get put onto the uncertain inode list. This is safe because we only put inodes onto the list when we're processing known inodes so the uncertain inode list isn't in use. We fix only one problem -- an entry that has a mathematically invalid inode numbers in them. If that's the case, we replace the inode number with NULLFSINO and we'll fix up the entry in phase 6. That info may conflict with the inode information, but we'll straighten out any inconsistencies there in phase4 when we process the inodes again. Errors involving bogus forward/back links, zero-length entries make the directory get trashed. if an entry references a free inode, ignore that fact for now. wait for the rest of phase 3 processing to hit that inode. If it looks like it's in use, we'll mark in use then. If not, we'll clear it and mark the inode map. then in phase 4, you can depend on the inode map. Entries that point to non-existent or free inodes, and extra blocks in the directory will get fixed in place in a later pass. Entries that point to a quota inode are marked TBD. If the directory internally points to the same block twice, the directory gets blown away. Note that processing uncertain inodes can add more inodes to the uncertain list if they're directories. So we loop until the uncertain list is empty. During inode verification, if the inode blocks are unknown, mark then as in-use by inodes. XXX HEURISTIC -- if we blow an inode away that has space, assume that the freespace btree is now out of wack. If it was ok earlier, it's certain to be wrong now. And the odds of this space free cancelling out the existing error is so small I'm willing to ignore it. Should probably do this via a global var and complain about this later. Assumption: All known inodes are now marked as in-use or free. Any inodes that we haven't found by now are hosed (lost) since we can't reach them via either the inode btrees or via directory entries. Directories are semi-clean. All '.' entries are good. Root '..' entry is good if root inode exists. All entries referencing non-existent inodes, free inodes, etc. XXX verify that either quota inode is 0 or NULLFSINO or if sb quota flag is non zero, verify that quota inode is NULLFSINO or is referencing a used, but disconnected inode. XXX if in no_modify mode, check for unclaimed blocks - Phase 4 - Check for inodes referencing duplicate blocks At this point, all known duplicate blocks are marked in the block map. However, some of the claimed blocks in the bmap may in fact be free because they belong to inodes that have to be cleared either due to being a trashed directory or because it's the first inode to claim a block that was then claimed later. There's a similar problem with meta-data blocks that are referenced by inode bmaps that are going to be freed once the inode (or directory) gets cleared. So at this point, we collect the duplicate blocks into extents and put them into the duplicate extent list. Mark the ag header blocks as in use. We then process each inode twice -- the first time we check to see if the inode claims a duplicate extent and we do NOT set the block bitmap. If the inode claims a duplicate extent, we clear the inode. Since the bitmap hasn't been set, that automatically frees all blocks associated with the cleared inode. If the inode is ok, process it a second time and set the bitmap since we know that this inode will live. The unlinked list gets cleared in every inode at this point as well. We no longer need to preserve it since we've discovered every inode we're going to find from it. verify existence of root inode. if it exists, check for existence of "lost+found". If it exists, mark the entry to be deleted, and clear the inode. All the inodes that were connected to the lost+found will be reconnected later. XXX HEURISTIC -- if we blow an inode away that has space, assume that the freespace btree is now out of wack. If it was ok earlier, it's certain to be wrong now. And the odds of this space free cancelling out the existing error is so small I'm willing to ignore it. Should probably do this via a global var and complain about this later. Clear the quota inodes if the inode btree says that they're not in use. The space freed will get picked up by phase 5. XXX Clear the quota inodes if the filesystem is being downgraded. - Phase 5 - Build inode allocation trees, freespace trees and agfl's for each ag. After this, we should be able to unmount the filesystem and remount it for real. For each ag: (if no in no_modify mode) scan bitmap first to figure out number of extents. calculate space required for all trees. Start with inode trees. Setup the btree cursor which includes the list of preallocated blocks. As a by-product, this will delete the extents required for the inode tree from the incore extent tree. Calculate how many extents will be required to represent the remaining free extent tree on disk (twice, one for bybno and one for bycnt). You have to iterate on this because consuming extents can alter the number of blocks required to represent the remaining extents. If there's slop left over, you can put it in the agfl though. Then, manually build the trees, agi, agfs, and agfls. XXX if in no_modify mode, scan the on-disk inode allocation trees and compare against the incore versions. Don't have to scan the freespace trees because we caught the problems there in phase2 and phase3. But if we cleared any inodes with space during phases 3 or 4, now is the time to complain. XXX - Free duplicate extent lists. ??? Assumptions: at this point, sim code having to do with inode creation/modification/deletion and space allocation work because the inode maps, space maps, and bmaps for all files in the filesystem are good. The only structures that are screwed up are the directory contents, which means that lookup may not work for beans, the root inode which exists but may be completely bogus and the link counts on all inodes which may also be bogus. Free the bitmap, the freespace tree. Flash the incore inode tree over from parent list to having full backpointers. realtime processing, if any -- (Skip to below if running in no_modify mode). Generate the realtime bitmap from the incore realtime extent map and slam the info into the realtime bitmap inode. Generate summary info from the realtime extent map. XXX if in no_modify mode, compare contents of realtime bitmap inode to the incore realtime extent map. generate the summary info from the incore realtime extent map. compare against the contents of the realtime summary inode. complain if bad. reset superblock counters, sync version numbers - Phase 6 - directory traversal -- check reference counts, attach disconnected inodes, fix up bogus directories Assumptions: all on-disk space and inode trees are structurally sound. Incore and on-disk inode trees agree on whether an inode is in use. Directories are structurally sound. All hashvalues are monotonically increasing and interior nodes are correct so lookups work. All legal directory entries point to inodes that are in use and exist. Shortform directories are fine except that the links haven't been checked for conflicts (cycles, ".." being correct, etc.). Longform directories haven't been checked for those problems either PLUS longform directories may still contain entries beginning with '/'. No zero-length entries exist (they've been deleted or converted to '/'). Root directory may or may not exist. orphange may or may not exist. Contents of either may be completely bogus. Entries may point to free or non-existent inodes. At this we point, we may need new incore structures and may be able to trash an old one (like the filesystem block map) If '/' is trashed, then reinitialize it. If no realtime inodes, make them and if necessary, slam the summary info into the realtime summary inode. Ditto with the realtime bitmap inode. Make orphanage (lost+found ???). Traverse each directory from '/' (unless it was created). Check directory structure and each directory entry. If the entry is bogus (points to a non-existent or free inode, for example), mark that entry TBD. Maintain link counts on all inodes. Currently, traversal is depth-first. Mark every inode reached as "reached" (includes bumping up link counts). If a entry points to a directory but the parent (..) disagrees, then blow away the entry. if the directory being pointed to winds up disconnected, it'll be moved to the orphanage (and the link count incremented to account for the link and the reached bit set then). If an entry points to a directory that we've already reached, then some entry is bad and should be blown away. It's easiest to blow away the current entry plus since presumably the parent entry in the reached directory points to another directory, then it's far more likely that the current entry is bogus (otherwise the parent should point at it). If an entry points to a non-existent of free inode, blow the entry away. Every time a good entry is encountered update the link count for the inode that the entry points to. After traversal, scan incore inode map for directories not reached. Go to first one and try and find its root by following .. entries. Once at root, run traversal algorithm. When algorithm terminates, move subtree root inode to the orphanage. Repeat as necessary until all disconnected directories are attached. Move all disconnected inodes to orphanage. - Phase 7: reset reference counts if required. Now traverse the on-disk inodes again, and make sure on-disk reference counts are correct. Reset if necessary. SKIP all unused inodes -- that also makes us skip the orphanage inode which we think is unused but is really used. However, the ref counts on that should be right so that's ok. --- multiple TB xfs_repair modify above to work in a couple of AGs at a time. The bitmaps should span only the current set of AGs. The key it scan the inode bmaps and keep a list of inodes that span multiple AG sets and keep the list in a data structure that's keyed off AG set # as well as inode # and also has a bit to indicate whether or not the inode will be cleared. Then in each AG set, when doing duplicate extent processing, you have to process all multi-AG-set inodes that claim blocks in the current AG set. If there's a conflict, you mark clear the inode in the current AG and you mark the multi-AG inode as "to be cleared". After going through all AGs, you can clear the to-be-cleared multi-AG-set inodes and pull them off the list. When building up the AG freespace trees, you walk the bmaps of all multi-AG-set inodes that are in the AG-set and include blocks claimed in the AG by the inode as used. This probably involves adding a phase 3-0 which would have to check all the inodes to see which ones are multi-AG-set inodes and set up the multi-AG-set inode data structure. Plus the process_dinode routines may have to be altered just a bit to do the right thing if running in tera-byte mode (call out to routines that check the multi-AG-set inodes when appropriate). To make things go faster, phase 3-0 could probably run in parallel. It should be possible to run phases 2-5 in parallel as well once the appropriate synchronization is added to the incore routines and the static directory leaf block bitmap is changed to be on the stack. Phase 7 probably can be in parallel as well. By in parallel, I mean that assuming that an AG-set contains 4 AGs, you could run 4 threads, 1 per AG in parallel to process the AG set. I don't see how phase 6 can be run in parallel though. And running Phase 8 in parallel is just silly. xfsprogs-4.3.0+nmu1ubuntu1.1/repair/agheader.c0000664000000000000000000003276212574431650016027 0ustar /* * Copyright (c) 2000-2001,2005 Silicon Graphics, Inc. * All Rights Reserved. * * 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. * * This program is distributed in the hope that it would be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Some checks are done * for validity of the value field based on what the security needs are. * Calls will be made to xfs_mac_valid or xfs_acl_valid routines if the * security attributes exist. They will be cleared if invalid. * No other values will be checked. The DMF folks do not have current * requirements, but may in the future. * * For leaf block attributes, it requires more processing. One sticky * point is that the attributes can be local (within the leaf) or * remote (outside the leaf in other blocks). Thinking of local only * if you get a bad attribute, and want to delete just one, it's a-okay * if it remains large enough to still be a leaf block attribute. Otherwise, * it may have to be converted to shortform. How to convert this and when * is an issue. This call is happening in Phase3. Phase5 will capture empty * blocks, but Phase6 allows you to use the libxfs library which knows * how to handle attributes in the kernel for converting formats. What we * could do is mark an attribute to be cleared now, but in phase6 somehow * have it cleared for real and then the format changed to shortform if * applicable. Since this requires more work than I anticipate can be * accomplished for the next release, we will instead just say any bad * attribute in the leaf block will make the entire attribute fork be * cleared. The simplest way to do that is to ignore the leaf format, and * call clear_dinode_attr to just make a shortform attribute fork with * zero entries. * * Another issue with handling repair on leaf attributes is the remote * blocks. To make sure that they look good and are not used multiple times * by the attribute fork, some mechanism to keep track of all them is necessary. * Do this in the future, time permitting. For now, note that there is no * check for remote blocks and their allocations. * * For btree formatted attributes, the model can follow directories. That * would mean go down the tree to the leftmost leaf. From there moving down * the links and processing each. They would call back up the tree, to verify * that the tree structure is okay. Any problems will result in the attribute * fork being emptied and put in shortform format. */ /* * This routine just checks what security needs are for attribute values * only called when root flag is set, otherwise these names could exist in * in user attribute land without a conflict. * If value is non-zero, then a remote attribute is being passed in */ static int valuecheck( struct xfs_mount *mp, char *namevalue, char *value, int namelen, int valuelen) { /* for proper alignment issues, get the structs and memmove the values */ xfs_mac_label_t macl; void *valuep; int clearit = 0; if ((namelen == SGI_ACL_FILE_SIZE && strncmp(namevalue, SGI_ACL_FILE, SGI_ACL_FILE_SIZE) == 0) || (namelen == SGI_ACL_DEFAULT_SIZE && strncmp(namevalue, SGI_ACL_DEFAULT, SGI_ACL_DEFAULT_SIZE) == 0)) { if (value == NULL) { valuep = malloc(valuelen); if (!valuep) do_error(_("No memory for ACL check!\n")); memcpy(valuep, namevalue + namelen, valuelen); } else valuep = value; if (xfs_acl_valid(mp, valuep) != 0) { clearit = 1; do_warn( _("entry contains illegal value in attribute named SGI_ACL_FILE " "or SGI_ACL_DEFAULT\n")); } if (valuep != value) free(valuep); } else if (strncmp(namevalue, SGI_MAC_FILE, SGI_MAC_FILE_SIZE) == 0) { if (value == NULL) { memset(&macl, 0, sizeof(xfs_mac_label_t)); memmove(&macl, namevalue+namelen, valuelen); valuep = &macl; } else valuep = value; if (xfs_mac_valid((xfs_mac_label_t *)valuep) != 1) { /* 1 is valid */ /* * if sysconf says MAC enabled, * temp = mac_from_text("msenhigh/mintlow", NULL) * copy it to value, update valuelen, totsize * This causes pushing up or down of all following * attributes, forcing a attribute format change!! * else clearit = 1; */ clearit = 1; do_warn( _("entry contains illegal value in attribute named SGI_MAC_LABEL\n")); } } else if (strncmp(namevalue, SGI_CAP_FILE, SGI_CAP_FILE_SIZE) == 0) { if ( valuelen != sizeof(xfs_cap_set_t)) { clearit = 1; do_warn( _("entry contains illegal value in attribute named SGI_CAP_FILE\n")); } } return(clearit); } /* * this routine validates the attributes in shortform format. * a non-zero return repair value means certain attributes are bogus * and were cleared if possible.
