By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

Spotted by Leonard Norrgard. + - Fix bug where the call to ntfs_attr_{put,reinit}_search_ctx() would + free the extent inode attached to the search context but leave it + attached to the base inode, so this would lead to memory corruption + and worse problems. Thanks to Szakacsits Szabolcs for spotting this. + We now don't close extent inodes any more at all and just leave it + to the closing of the base inode to dispose of all the extent inodes. + - Add sanity check to ntfs_inode_close() to detect attempts at closing + extent inodes. + - Don't free extent inodes in attrib.c! (Szakacsits Szabolcs) + - Return the attribute list attribute when enumerating attributes, too. + Thanks to Szakacsits Szabolcs for pointing this problem out. + - New API function provided by unistr.[hc] and use it in mkntfs: + ntfs_ucsnlen(). + - New API function provided by attrib.[hc] and use it in mkntfs: + ntfs_resident_attr_value_resize(), + ntfs_attr_truncate(). -- WIP + - New API functions provided by inode.[hc]: + ntfs_inode_mark_dirty(), + ntfs_inode_sync(). + - Change ntfs_inode_close() to write out dirty inodes and inode extents. + - New API functions provided by lcnalloc.[hc]: + ntfs_cluster_{alloc,free}(). -- WIP + - New API function provided by bitmap.[hc]: + ntfs_bitmap_{set,clear}_run(). -- WIP + - Extend the volume.h::ntfs_volume structure with variables required by + the cluster and mft allocators and set them up in + volume.c::ntfs_volume_startup(). + - ntfs_umount() now also does an fdatasync() on the device before + closing it. + - Added new utility ntfstruncate, primarily to be able to test the + new ntfs_attr_truncate() function, it is not compiled by default. + Note, the library can currently only make attributes smaller and it + only works on uncompressed, unencrypted inodes which do not contain + attribute lists, i.e. on simple files, but that was quite a lot of + new code in itself which needs a lot of testing! + - Fix library to never issue writes on volumes that have been mounted + read-only. + - New API provided by mft.[hc]: + ntfs_mft_record_{alloc,free}(). -- WIP + +12/03/2002 - 1.6.0 - More mkntfs options and cleanups. + Fix typo in usage information of mkntfs. Thanks to Richard Russon for + spotting it. + Change version number in mkntfs and ntfsfix to match the linux-ntfs + release version number. + Added two new options to mkntfs; -I, which disables content indexing + on the volume and -C, which enables compression on the volume. + +01/02/2002 - Attempt to fix compile warnings on powerpc. + Attempt to fix compile warnings on powerpc.

This is because they are not really useful except if you are + a developer wanting to play about. + +10/06/2001 - 1.0.0 - mkntfs release and bugfixes to ntfslib and the others. + Also, released ldm which dumps the ldm database on Win2k/XP dynamic + disks. + A man page for mkntfs is also installed by make install so man 8 mkntfs + can be used to show the recognised command line options. + Building of shared libraries is disabled by default as it breaks on + some systems. + Probably need at least gcc-2.95 or something like that from now on. + +02/02/2001 - Started ChangeLog. + diff --git a/INSTALL b/INSTALL new file mode 100644 index 0000000..9f87917 --- /dev/null +++ b/INSTALL @@ -0,0 +1,237 @@ +Quick installation +================== + + In most cases it should be sufficient to do: + + ./configure + make + make install + + The above will compile and install the NTFS library and utility +programs into /usr/local/lib and /usr/local/bin respectively. The man +pages will be installed by default in /usr/local/man. + +Basic Installation +================== + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + The `--enable-debug' option to `configure' will enable additional debugging +checks in the code as well as debugging information output which will be +emitted to stdout. + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ atchitectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `./config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options.

(Note, that some attributes +cannot be non-resident.) + +Non-resident attributes +======================= + +Non-resident attributes contain only their non-resident attribute header in the +mft record and the actual attribute value is stored anywhere on the volume +(but not in other mft records). + +The value of the attribute is saved as a sequence of clusters, named virtual +clusters, beginning at virtual cluster number (vcn) zero. Each vcn corresponds +to a cluster on the volume, or a logical cluster number (lcn). The lcns on the +volume begin with lcn zero for the very first cluster on the volume. + +The location of the attribute value is described by the mapping pairs array +present in the non-resident attribute header structure. The mapping pairs array +contains, in compressed form, the mapping between the attribute's vcns and the +corresponding lcns on the volume. + +When the mapping pairs array of a non-resident attribute becomes too large to +fit in the mft record or when there are so many attributes in the mft record +that, even though all attributes that can be non-resident have been made +non-resident, they still do not fit in the mft record, the larger non-resident +attributes are moved away from the mft record to make space. + +This is done by moving whole non-resident attribute header structures to other +mft records and/or by splitting the mapping pairs array of attributes into +several non-resident attribute headers, each containing a chunk of the +original mapping pairs array. These non-resident attribute headers each +describing the same attribute value (but different parts of it) are called +extents. + +Attribute list attribute +======================== + +The attribute list attribute is then added to the base mft record to describe +the location of each attribute. + +The attribute list attribute lists all attributes that belong to this mft +record (with the exception of itself). Each entry in the attribute list +describes the attribute listed and in which mft record it's attribute header can +be found. For resident attributes this will be the same number as the base mft +record in which the attribute list attribute is located itself. For non-resident +attributes, this will be another mft record, called an extension mft record. +Naturally, all extension mft records point back to their base mft record. + +Only one attribute is stored in an extension mft record, even if the attribute +is very small. At least this is the case with Windows NT4 SP6a driver. + +Should the mapping pairs array of an attribute become so large as to not fit +into an extenstion mft record, even though it's attribute is the only attribute +in this extension record, then the attribute is splitt into several extents. +The first extent starts at vcn 0 and has it's lowest vcn value set to zero and +continues up to it's highest vcn value. This is determined by splitting up the +mapping pairs array into chunks which just fit into an extension mft record +each. Thus the first mapping pairs array chunk will determine the value of +the highest vcn for the first extent. The attribute list will contain an entry +for this extent. Then, a second extent is created which has it's lowest vcn +value set to the highest vcn of the previous extent + 1 and the next chunk of +the mapping pairs array is inserted into this extent. Again, an entry for this +extent is placed into the attribute list, and so on, until the whole +non-resident attribute's mapping pairs array has been accomodated. + +Should the attribute list become too big to fit inside the base mft record it +is made non-resident. However, it's maximum value size is determined by the +Windows cache manager to be 256kb (the size of a VACB). Also, the mapping pairs +array of the attribute list has to fit inside the base mft record, as an +attribute list can't be described by itself and attribute lists are not allowed to be nested. + +Compressed attributes +===================== + +The attribute value of each $DATA attribute can be compressed to save space. +If this is the case, the ATTR_IS_COMPRESSED flag is set. + +See the discussion on compression in include/attrib.h for more details. +FIXME: The discussion belongs here!

Just search for "Attribute compression". +FIXME: Should merge the info from there into this document some time. + +Compressed data is organized in logical "compression" blocks (cb). Each cb has +a size (cb_size) of 2^compression_unit clusters. In all versions of Windows, +NTFS (NT/2k/XP, NTFS 1.2-3.1), the only valid compression_unit is 4, IOW, each +cb is 2^4 = 16 clusters in size. + +We detect and warn about a compression_unit != 4 but we try to decompress the +data anyway. + +Compression is only supported for cluster sizes between 512 and 4096. Thus a +cb can be between 8 and 64kiB in size. + +Each cb is independent of the other cbs and is thus the minimal unit we have +to parse even if we wanted to decompress only one byte. + +Also, a cb can be totally uncompressed and this would be indicated as a sparse +cb in the runlist. + +Thus, we need to look at the runlist of the compressed data stream, starting +at the beginning of the first cb overlapping @page. So we convert the page +offset into units of clusters (vcn), and round the vcn down to a mutliple of +cb_size clusters. + +We then scan the runlist for the appropriate position. Based on what we find +there, we decide how to proceed. + +If the cb is not compressed at all, and covers the whole of @page, we pretend +to be accessing an uncompressed file, so we fall back to what we do in +aops.c::ntfs_file_readpage(), i.e. we do: + return block_read_full_page(page, ntfs_file_get_block); + +If the cb is completely sparse, and covers the whole of @page, we can just +zero out @page and complete the io (set @page up-to-date, unlock it, and +finally return 0). + +In all other cases we initiate the decompression engine, but first some more +on the compression algorithm. + +Before compression the data of each cb is further divided into 4kiB blocks, we +call them "sub compression" blocks (sb), each including a header specifying +its compressed length. So we could just scan the cb for the first sb +overlapping @page and skip the sbs before that, or we could decompress the +whole cb injecting the superfluous decompressed pages into the page cache as a +form of read ahead (this is what zisofs does for example). + +In either case, we then need to read and decompress all sbs overlapping @page, +potentially having to decompress one or more other cbs, too. + +As soon as @page is completed we could either stop or continue until we finish +the current cb, injecting pages as we go along (again following the zisofs +example). + +Because the sbs follow each other directly, we need to actually read in the +whole cb in order to be able to scan through the cb to find the first sb +overlapping @page, so it does make sense to follow the zisofs approach of +decompressing the whole cb and injecting pages as we go along. So all +discussion from now on will assume that we are going to do that. Although it +might make sense not to decompress any sbs locate before @page because this +would be a kind of "read-behind" which is probably silly, unless someone is +reading the file backwards. Performing read-ahead by decompressing all sbs +following @page OTOH, is very likely to be a good idea. + +So, we read the whole cb from disk and start at the first sb. + +As mentioned above, each sb is started with a header. The header is 16 bits of +which the lower twelve bits (i.e. bits 0 to 11) are the length (L) - 3 of the +sb (including the two bytes for the header itself, or L - 1 not counting the +two bytes for the header). The higher four bits are set to 1011 (0xb) by the +compressor for a compressed block, or to 0000 for an uncompressed block, but +the decompressor only checks the most significant bit taking a 1 to signify a +compressed block, and a 0 an uncompressed block. + +So from the header we know how many compressed bytes we need to decompress to +obtain the next 4kiB of uncompressed data and if we didn't want to decompress +this sb we could just seek to the next next one using the length read from the +header. We could then continue seeking until we reach the first sb overlapping +@page. + +In either case, we will reach a sb which we want to decompress. + +Having dealt with the 16-bit header of the sb, we now have length bytes of +compressed data to decompress. This compressed stream is further split into +tokens which are organized into groups of eight tokens. Each token group (tg) +starts with a tag byte, which is an eight bit bitmap, the bits specifying the +type of each of the following eight tokens. The least significant bit (LSB) +corresponds to the first token and the most significant bit (MSB) corresponds +to the last token. + +The two types of tokens are symbol tokens, specified by a zero bit, and phrase +tokens, specified by a set bit. + +A symbol token (st) is a single byte and is to be taken literally and copied +into the sliding window (the decompressed data). + +A phrase token (pt) is a pointer back into the sliding window (in bytes), +together with a length (again in bytes), starting at the byte the back pointer +is pointing to. Thus a phrase token defines a sequence of bytes in the sliding +window which need to be copied at the current position into the sliding window +(the decompressed data stream). + +Each pt consists of 2 bytes split into the back pointer (p) and the length (l), +each of variable bit width (but the sum of the widths of p and l is fixed at +16 bits). p is at least 4 bits and l is at most 12 bits. + +The most significant bits contain the back pointer (p), while the least +significant bits contain the length (l). + +l is actually stored as the number of bytes minus 3 (unsigned) as anything +shorter than that would be at least as long as the 2 bytes needed for the +actual pt, so no compression would be achieved. + +p is stored as the positive number of bytes minus 1 (unsigned) as going zero +bytes back is meaningless. + +Note that decompression has to occur byte by byte, as it is possible that some +of the bytes pointed to by the pt will only be generated in the sliding window +as the byte sequence pointed to by the pt is being copied into it! + +To give a concrete example; a block full of the letter A would be compressed +by storing the byte A once as a symbol token, followed by a single phrase +token with back pointer -1 (p = 0, therefore go back by -(0 + 1) bytes) and +length 4095 (l=0xffc, therefore length 0xffc + 3 bytes). + +The widths of p and l are determined from the current position within the +decompressed data (cur_pos). We don't actually care about the widths as such +however, but instead we want the mask (l_mask) with which to AND the pt to +obtain l, and the number of bits (p_shift) by which to right shift the pt to +obtain p. These are determined using the following algorithm: + +for (i = cur_pos, l_mask = 0xfff, p_shift = 12; i >= 0x10; i >>= 1) { + l_mask >>= 1; + p_shift--; +} + +Note, that as usual in NTFS, the sb header, as well as each pt, are stored in +little endian format. + diff --git a/doc/system_files.txt b/doc/system_files.txt new file mode 100644 index 0000000..9ed1336 --- /dev/null +++ b/doc/system_files.txt @@ -0,0 +1,41 @@ +System files mft record numbers.

On Windows NT/2k, X always is 16 clusters (compression_unit = 4). + * + * There are three different cases of how a compression block of X clusters + * can be stored: + * + * 1) The data in the block is all zero (a sparse block): + * This is stored as a sparse block in the runlist, i.e. the runlist + * entry has length = X and lcn = -1.

I.e. if compression has a small effect so that the + * compressed data still occupies X clusters, then the uncompressed data + * is stored in the block. + * This case is recognised by the fact that the runlist entry has + * length = X and lcn >= 0. The mapping pairs array stores this as + * normal with a run length of X and some specific delta_lcn, i.e. + * delta_lcn has to be present. + * + * 3) The data in the block is compressed: + * The common case. This case is recognised by the fact that the run + * list entry has length L < X and lcn >= 0. The mapping pairs array + * stores this as normal with a run length of X and some specific + * delta_lcn, i.e. delta_lcn has to be present. This runlist entry is + * immediately followed by a sparse entry with length = X - L and + * lcn = -1. The latter entry is to make up the vcn counting to the + * full compression block size X. + * + * In fact, life is more complicated because adjacent entries of the same type + * can be coalesced. This means that one has to keep track of the number of + * clusters handled and work on a basis of X clusters at a time being one + * block. An example: if length L > X this means that this particular runlist + * entry contains a block of length X and part of one or more blocks of length + * L - X. Another example: if length L < X, this does not necessarily mean that + * the block is compressed as it might be that the lcn changes inside the block + * and hence the following runlist entry describes the continuation of the + * potentially compressed block. The block would be compressed if the + * following runlist entry describes at least X - L sparse clusters, thus + * making up the compression block length as described in point 3 above. (Of + * course, there can be several runlist entries with small lengths so that the + * sparse entry does not follow the first data containing entry with + * length < X.) + * + * NOTE: At the end of the compressed attribute value, there most likely is not + * just the right amount of data to make up a compression block, thus this data + * is not even attempted to be compressed.

First is the area between the end of the mft zone + * and the end of the volume, and second is the area between the start of the + * volume and the start of the mft zone. On unmodified/standard NTFS 1.x + * volumes, the second data zone doesn't exist due to the mft zone being + * expanded to cover the start of the volume in order to reserve space for the + * mft bitmap attribute. + * + * This is not the prettiest function but the complexity stems from the need of + * implementing the mft vs data zoned approach and from the fact that we have + * access to the lcn bitmap in portions of up to 8192 bytes at a time, so we + * need to cope with crossing over boundaries of two buffers. Further, the fact + * that the allocator allows for caller supplied hints as to the location of + * where allocation should begin and the fact that the allocator keeps track of + * where in the data zones the next natural allocation should occur, contribute + * to the complexity of the function. But it should all be worthwhile, because + * this allocator should: 1) be a full implementation of the MFT zone approach + * used by Windows, 2) cause reduction in fragmentation as much as possible, + * and 3) be speedy in allocations (the code is not optimized for speed, but + * the algorithm is, so further speed improvements are probably possible). + * + * FIXME: We should be monitoring cluster allocation and increment the MFT zone + * size dynamically but this is something for the future. We will just cause + * heavier fragmentation by not doing it and I am not even sure Windows would + * grow the MFT zone dynamically, so it might even be correct not to do this. + * The overhead in doing dynamic MFT zone expansion would be very large and + * unlikely worth the effort. (AIA) + * + * TODO: I have added in double the required zone position pointer wrap around + * logic which can be optimized to having only one of the two logic sets. + * However, having the double logic will work fine, but if we have only one of + * the sets and we get it wrong somewhere, then we get into trouble, so + * removing the duplicate logic requires _very_ careful consideration of _all_ + * possible code paths.

If omitted, +.B mkntfs +automagically figures the file system size. +.SH OPTIONS +.TP +.BI \-s " sector-size" +Specify the size of sectors in bytes. Valid sector size values are 256, 512, +1024, 2048 and 4096 bytes per sector. If omitted, +.B mkntfs +.I sector-size +is determined automatically and if that fails a default of 512 +bytes per sector is used. +.TP +.BI \-c " cluster-size" +Specify the size of clusters in bytes. Valid cluster size values are powers of +two, with at least 256, and at most 65536 bytes per cluster. If omitted, +.B mkntfs +.I cluster-size +is determined by the volume size. The value is determined as +follows: +.TS +lB lB lB +l l r. +Volume size Default cluster +0 - 512MB 512 bytes +512MB - 1GB 1024 bytes +1GB - 2GB 2048 bytes +2GB + 4096 bytes +.TE + +Note that the default cluster size is set to be at least equal to the sector +size as a cluster cannot be smaller than a sector. Also, note that values +greater than 4096 have the side effect that compression is disabled on the +volume (due to limitations in the NTFS compression algorithm currently in use +by Windows). +.TP +.BI \-L " volume-label" +Set the volume label for the filesystem. +.TP +.BI \-z " mft-zone-multiplier" +Set the MFT zone multiplier, which determines the size of the MFT zone to use +on the volume. The MFT zone is the area at the beginning of the volume reserved +for the master file table (MFT), which stores the on disk inodes (MFT records). +It is noteworthy that small files are stored entirely within the inode; +thus, if you expect to use the volume for storing large numbers of very small +files, it is useful to set the zone multiplier to a higher value. Note, that +the MFT zone is resized on the fly as required during operation of the NTFS +driver but choosing a good value will reduce fragmentation. Valid values +are 1, 2, 3 and 4. The values have the following meaning: +.TS +lB lB +lB lB +c l. +MFT zone MFT zone size +multiplier (% of volume size) +1 12.5% (default) +2 25.0% +3 37.5% +4 50.0% +.TE +.TP +.B \-f +Same as +.BR \-Q . +.TP +.B \-Q +Perform quick format. This will skip both zeroing of the volume and bad sector +checking. +.TP +.B \-n +Causes +.B mkntfs +to not actually create a filesystem, but display what it would do if it were +to create a filesystem. All steps of the format are carried out except the +actual writing to the device. +.TP +.B \-q +Quiet execution; only errors are written to stderr, no output to stdout +occurs at all. Useful if +.B mkntfs +is run in a script. +.TP +.B \-v +Verbose execution. +.TP +.B \-vv +Really verbose execution; includes the verbose output from the +.B \-v +option as well as additional output useful for debugging +.B mkntfs. +.TP +.B \-C +Enable compression on the volume. +.TP +.B \-F +Force +.B mkntfs +to run, even if the specified +.I device +is not a block special device, or appears to be mounted. +.TP +.B \-I +Disable content indexing on the volume. (This is only meaningful on +Windows 2000 and later. Windows NT 4.0 and earlier ignore this as they do +not implement content indexing at all.) +.TP +.B \-V +Print the version number of +.B mkntfs +and exit. +.TP +.B \-l +Print the licensing information of +.B mkntfs +and exit. +.TP +.B \-h +Print the usage information of +.B mkntfs +and exit. +.SH BUGS +.B mkntfs +writes the backup boot sector to the last sector of the block +.I device +being formatted. However, current versions of the Linux kernel (all versions +up to and including todays 2.4.18) either only report an even number of sectors +when the sector size is below 1024 bytes, which is the case for most hard +drives today (512 bytes sector size) or they return the correct number but +accessing the last sector fails. Either way, this means that when a partition +has an odd number of 512-byte sectors, the last sector is either not reported +to us at all or it is not writable by us and hence the created NTFS volume +will either have the backup boot sector placed one sector ahead of where it +should be or it cannot be written at all. For this reason, +.B mkntfs +marks the NTFS volume dirty, so that when you reboot into Windows, check disk +runs automatically and creates a copy of the backup boot sector in the correct +location. This also has the benefit of catching any bugs in +.B mkntfs +as check disk would find any corrupt structures and repair them, as well as +report them. - If you do see any problems reported, please report the messages +to the author. +.br +There may be other bugs.

It only tries to leave the NTFS partition in a +not-so-inconsistent state after the NTFS driver has written to it. +.sp +\fBntfsfix\fP appeared because MS chkdsk is well known for its +stupidity when fixing altered partitions. Because the main problems +are journal files, \fBntfsfix\fP aims to fix those issues. +.sp +Running ntfsfix after mounting NTFS partitions read-write is recommended +for reducing the chance of severe data loss when NT/W2K tries to remount +the affected partition(s). +.sp +In order to use \fBntfsfix\fP you must unmount the NTFS partition, and run +ntfsfix device, where device is the NTFS partition. After this, you can +safely reboot into NT/W2K. Please note that \fBntfsfix\fP is not a +chkdsk-like tool, and so is not guaranteed that it could fix all the +alterations provoked by the NTFS driver. + +.SH AUTHOR +This manual page was written by David Martínez Moreno +, for the Debian GNU/Linux +system (but may be used by others). +.SH AVAILABILITY +.B ntfsfix +is part of the linux-ntfs package and is available from +http://linux-ntfs.sourceforge.net/. +.SH SEE ALSO +.BR mkntfs (8), +.BR ntfsprogs (8) diff --git a/ntfsprogs/ntfsfix.c b/ntfsprogs/ntfsfix.c new file mode 100644 index 0000000..587e8e2 --- /dev/null +++ b/ntfsprogs/ntfsfix.c @@ -0,0 +1,329 @@ +/** + * NtfsFix - Part of the Linux-NTFS project. + * + * Copyright (c) 2000-2003 Anton Altaparmakov. + * + * This utility will attempt to fix a partition that has been damaged by the + * current Linux-NTFS driver.

At present it can be used to enlarge or shrink a +defragmented NTFS filesystem located on an unmounted +.I device +(usually a disk partition). The new volume will have +.I size +bytes. +The +.I size +parameter may have one of the optional modifiers +\fBk\fR, \fBM\fR, \fBG\fR, which means the +.I size +parameter is given in kilo-, mega- or gigabytes respectively. +.B ntfsresize +conforms to the SI, ATA, IEEE standards and the disk manufacturers +by using k=10^3, M=10^6 and G=10^9. +The options +.B -i +and +.B -s +are mutually exclusive. If both of them are omitted then the +NTFS filesystem will be enlarged to the device size. +Before a real resize operation, always make a read-only +test run using the +.B -n +option. +.PP +The +.B ntfsresize +program doesn't manipulate the size of partitions. +To do that you have to use a disk partitioning tool, for example +.BR fdisk (8). +.PP +If you wish to enlarge an NTFS filesystem, +you must first make sure you can expand the size of the +underlying partition first. This can be done using +.BR fdisk (8) +by deleting the partition and recreating it with a larger size. +Then you may use +.B ntfsresize +to enlarge the size of the filesystem. +.PP +If you wish to shrink an NTFS partition, first use +.B ntfsresize +to shrink the size of the filesystem. Then you may use +.BR fdisk (8) +to shrink the size of the partition by deleting the +partition and recreating it with the smaller size. +.PP +.B IMPORTANT! +When recreating the partition with +.BR fdisk (8) +make sure you create it with the same starting +disk cylinder and partition type +as before. +If you enlarge a partition make sure it will not overlap with +an other existing partition! +If you shrink a partition, do not make +it smaller than the new size of the NTFS filesystem! +Otherwise you may lose your entire filesystem. +Also make sure you set the bootable flag for the partition if it +existed before. Failing to do so you might not be able to boot your +computer from the disk! +.PP +Note, +.B ntfsresize +schedules 'chkdsk' to make an NTFS consistency check +when you will boot Windows. Windows may force a reboot after +the successful consistency check. + +.SH OPTIONS +.TP +.B -f +Forces ntfsresize to proceed with the filesystem resize operation, overriding +some safety checks which +.B ntfsresize +normally enforces. You can use this +parameter multiply times if you want to overcome every single safety checks. +.TP +.B -h +Display help and exit. +.TP +.B -i +Using this option you can calculate the smallest shrunken volume size supported. +This option will not make any changes to the filesystem. +.TP +.B -n +Use this option to make a test run before doing the real resize operation. +Volume will be opened read-only and +.B ntfsresize +displays what it would do if it were to resize the filesystem. +.TP +.B -s \fIsize\fR[\fBk\fR|\fBM\fR|\fBG\fR] +Resize volume to \fIsize\fR[\fBk\fR|\fBM\fR|\fBG\fR] bytes. +The optional modifiers \fBk\fR, \fBM\fR, \fBG\fR mean the +.I size +parameter is given in kilo-, mega- or gigabytes respectively. +Conforming to standards, k=10^3, M=10^6 and G=10^9. +.SH BUGS +No bugs are known or has been reported so far in the current version. +If you find otherwise, please report it to +(no subscription needed).

Then it +will print a list giving the inode number, name and size. +.SS Undelete +.PP +The +.I undelete +mode takes the inode and recovers as much of the data as possible. It saves the +result to another location. Partly for safety, but mostly because NTFS write +support isn't finished. +.SS Copy +.PP +This is a wizard's option. It will save a portion of the MFT to a file. This +probably only be useful when debugging +.I ntfsundelete +.SS Notes +.B ntfsundelete +only ever +.B reads +from the NTFS Volume. +.B ntfsundelete +will never change the volume. +.SH CAVEATS +.SS Miracles +.B ntfsundelete +cannot perform the impossible. +.PP +When a file is deleted the MFT Record is marked as not in use and the bitmap +representing the disk usage is updated. If the power isn't turned off +immediately, the free space, where the file used to live, may become +overwritten. Worse, the MFT Record may be reused for another file. If this +happens it is impossible to tell where the file was on disk. +.PP +Even if all the clusters of a file are not in use, there is no guarantee that +they haven't been overwritten by some short\-lived file. +.SS Locale +In NTFS all the filenames are stored as Unicode. They will be converted into +the current locale for display by +.BR ntfsundelete . +The utility has successfully displayed some Chinese pictogram filenames and then +correctly recovered them. +.SS Extended MFT Records +In rare circumstances, a single MFT Record will not be large enough to hold the +metadata describing a file (a file would have to be in hundreds of fragments +for this to happen). In these cases one MFT record may hold the filename, but +another will hold the information about the data. +.B ntfsundelete +will not try and piece together such records. It will simply show unnamed files +with data. +.SS Compressed and Encrypted Files +.B ntfsundelete +cannot recover compressed or encrypted files. When scanning for them, it will +display as being 0% recoverable. +.SS The Recovered File's Size and Date +To recover a file +.B ntfsundelete +has to read the file's metadata. Unfortunately, this isn't always intact. +When a file is deleted, the metadata can be left in an inconsistant state. e.g. +the file size may be zero; the dates of the file may be set to the time it was +deleted, or random. +.br +To be safe +.B ntfsundelete +will pick the largest file size it finds and write that to disk. It will also +try and set the file's date to the last modified date. This date may be the +correct last modified date, or something unexpected. +.SH OPTIONS +Below is a summary of all the options that +.B ntfsundelete +accepts. All options have two equivalent names. The short name is preceded by +.BR \- +and the long name is preceded by +.BR \-\- . +Any single letter options, that don't take an argument, can be combined into a +single command, e.g. +.BR \-fv +is equivalent to +.BR "\-f \-v" . +Long named options can be abbreviated to any unique prefix of their name. +.TP +.BI "\-b " num +.br +.ns +.TP +.BI "\-\-byte " num +If any clusters of the file cannot be recovered, the missing parts will be +filled with this byte. The default is zeros. +.TP +.B \-C +.br +.ns +.TP +.B \-\-case +When scanning an NTFS volume, any filename matching (using the +.B \-\-match +option) is case\-insensitive.
