You have been warned! Even better is to simply use the Device-Mapper for linear raid and then you do not have this problem with odd numbers of sectors. - - -ChangeLog -========= - -2.1.30: - - Fix writev() (it kept writing the first segment over and over again - instead of moving onto subsequent segments). - - Fix crash in ntfs_mft_record_alloc() when mapping the new extent mft - record failed. -2.1.29: - - Fix a deadlock when mounting read-write. -2.1.28: - - Fix a deadlock. -2.1.27: - - Implement page migration support so the kernel can move memory used - by NTFS files and directories around for management purposes. - - Add support for writing to sparse files created with Windows XP SP2. - - Many minor improvements and bug fixes. -2.1.26: - - Implement support for sector sizes above 512 bytes (up to the maximum - supported by NTFS which is 4096 bytes). - - Enhance support for NTFS volumes which were supported by Windows but - not by Linux due to invalid attribute list attribute flags. - - A few minor updates and bug fixes. -2.1.25: - - Write support is now extended with write(2) being able to both - overwrite existing file data and to extend files. Also, if a write - to a sparse region occurs, write(2) will fill in the hole. Note, - mmap(2) based writes still do not support writing into holes or - writing beyond the initialized size. - - Write support has a new feature and that is that truncate(2) and - open(2) with O_TRUNC are now implemented thus files can be both made - smaller and larger. - - Note: Both write(2) and truncate(2)/open(2) with O_TRUNC still have - limitations in that they - - only provide limited support for highly fragmented files. - - only work on regular, i.e. uncompressed and unencrypted files. - - never create sparse files although this will change once directory - operations are implemented. - - Lots of bug fixes and enhancements across the board. -2.1.24: - - Support journals ($LogFile) which have been modified by chkdsk. This - means users can boot into Windows after we marked the volume dirty. - The Windows boot will run chkdsk and then reboot. The user can then - immediately boot into Linux rather than having to do a full Windows - boot first before rebooting into Linux and we will recognize such a - journal and empty it as it is clean by definition. - - Support journals ($LogFile) with only one restart page as well as - journals with two different restart pages. We sanity check both and - either use the only sane one or the more recent one of the two in the - case that both are valid. - - Lots of bug fixes and enhancements across the board. -2.1.23: - - Stamp the user space journal, aka transaction log, aka $UsnJrnl, if - it is present and active thus telling Windows and applications using - the transaction log that changes can have happened on the volume - which are not recorded in $UsnJrnl. - - Detect the case when Windows has been hibernated (suspended to disk) - and if this is the case do not allow (re)mounting read-write to - prevent data corruption when you boot back into the suspended - Windows session. - - Implement extension of resident files using the normal file write - code paths, i.e. most very small files can be extended to be a little - bit bigger but not by much. - - Add new mount option "disable_sparse". (See list of mount options - above for details.) - - Improve handling of ntfs volumes with errors and strange boot sectors - in particular. - - Fix various bugs including a nasty deadlock that appeared in recent - kernels (around 2.6.11-2.6.12 timeframe). -2.1.22: - - Improve handling of ntfs volumes with errors. - - Fix various bugs and race conditions. -2.1.21: - - Fix several race conditions and various other bugs. - - Many internal cleanups, code reorganization, optimizations, and mft - and index record writing code rewritten to fit in with the changes. - - Update Documentation/filesystems/ntfs.txt with instructions on how to - use the Device-Mapper driver with NTFS ftdisk/LDM raid. -2.1.20: - - Fix two stupid bugs introduced in 2.1.18 release. -2.1.19: - - Minor bugfix in handling of the default upcase table. - - Many internal cleanups and improvements. Many thanks to Linus - Torvalds and Al Viro for the help and advice with the sparse - annotations and cleanups. -2.1.18: - - Fix scheduling latencies at mount time. (Ingo Molnar) - - Fix endianness bug in a little traversed portion of the attribute - lookup code. -2.1.17: - - Fix bugs in mount time error code paths. -2.1.16: - - Implement access time updates (including mtime and ctime). - - Implement fsync(2), fdatasync(2), and msync(2) system calls. - - Enable the readv(2) and writev(2) system calls. - - Enable access via the asynchronous io (aio) API by adding support for - the aio_read(3) and aio_write(3) functions. -2.1.15: - - Invalidate quotas when (re)mounting read-write. - NOTE: This now only leave user space journalling on the side. (See - note for version 2.1.13, below.) -2.1.14: - - Fix an NFSd caused deadlock reported by several users. -2.1.13: - - Implement writing of inodes (access time updates are not implemented - yet so mounting with -o noatime,nodiratime is enforced). - - Enable writing out of resident files so you can now overwrite any - uncompressed, unencrypted, nonsparse file as long as you do not - change the file size. - - Add housekeeping of ntfs system files so that ntfsfix no longer needs - to be run after writing to an NTFS volume. - NOTE: This still leaves quota tracking and user space journalling on - the side but they should not cause data corruption. In the worst - case the charged quotas will be out of date ($Quota) and some - userspace applications might get confused due to the out of date - userspace journal ($UsnJrnl). -2.1.12: - - Fix the second fix to the decompression engine from the 2.1.9 release - and some further internals cleanups. -2.1.11: - - Driver internal cleanups. -2.1.10: - - Force read-only (re)mounting of volumes with unsupported volume - flags and various cleanups. -2.1.9: - - Fix two bugs in handling of corner cases in the decompression engine. -2.1.8: - - Read the $MFT mirror and compare it to the $MFT and if the two do not - match, force a read-only mount and do not allow read-write remounts. - - Read and parse the $LogFile journal and if it indicates that the - volume was not shutdown cleanly, force a read-only mount and do not - allow read-write remounts. If the $LogFile indicates a clean - shutdown and a read-write (re)mount is requested, empty $LogFile to - ensure that Windows cannot cause data corruption by replaying a stale - journal after Linux has written to the volume. - - Improve time handling so that the NTFS time is fully preserved when - converted to kernel time and only up to 99 nano-seconds are lost when - kernel time is converted to NTFS time. -2.1.7: - - Enable NFS exporting of mounted NTFS volumes. -2.1.6: - - Fix minor bug in handling of compressed directories that fixes the - erroneous "du" and "stat" output people reported. -2.1.5: - - Minor bug fix in attribute list attribute handling that fixes the - I/O errors on "ls" of certain fragmented files found by at least two - people running Windows XP. -2.1.4: - - Minor update allowing compilation with all gcc versions (well, the - ones the kernel can be compiled with anyway). -2.1.3: - - Major bug fixes for reading files and volumes in corner cases which - were being hit by Windows 2k/XP users. -2.1.2: - - Major bug fixes alleviating the hangs in statfs experienced by some - users. -2.1.1: - - Update handling of compressed files so people no longer get the - frequently reported warning messages about initialized_size != - data_size. -2.1.0: - - Add configuration option for developmental write support. - - Initial implementation of file overwriting. (Writes to resident files - are not written out to disk yet, so avoid writing to files smaller - than about 1kiB.) - - Intercept/abort changes in file size as they are not implemented yet. -2.0.25: - - Minor bugfixes in error code paths and small cleanups. -2.0.24: - - Small internal cleanups. - - Support for sendfile system call. (Christoph Hellwig) -2.0.23: - - Massive internal locking changes to mft record locking. Fixes - various race conditions and deadlocks. - - Fix ntfs over loopback for compressed files by adding an - optimization barrier. (gcc was screwing up otherwise ?) - Thanks go to Christoph Hellwig for pointing these two out: - - Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs(). - - Fix ntfs_free() for ia64 and parisc. -2.0.22: - - Small internal cleanups. -2.0.21: - These only affect 32-bit architectures: - - Check for, and refuse to mount too large volumes (maximum is 2TiB). - - Check for, and refuse to open too large files and directories - (maximum is 16TiB). -2.0.20: - - Support non-resident directory index bitmaps. This means we now cope - with huge directories without problems. - - Fix a page leak that manifested itself in some cases when reading - directory contents. - - Internal cleanups. -2.0.19: - - Fix race condition and improvements in block i/o interface. - - Optimization when reading compressed files. -2.0.18: - - Fix race condition in reading of compressed files. -2.0.17: - - Cleanups and optimizations. -2.0.16: - - Fix stupid bug introduced in 2.0.15 in new attribute inode API. - - Big internal cleanup replacing the mftbmp access hacks by using the - new attribute inode API instead. -2.0.15: - - Bug fix in parsing of remount options. - - Internal changes implementing attribute (fake) inodes allowing all - attribute i/o to go via the page cache and to use all the normal - vfs/mm functionality. -2.0.14: - - Internal changes improving run list merging code and minor locking - change to not rely on BKL in ntfs_statfs(). -2.0.13: - - Internal changes towards using iget5_locked() in preparation for - fake inodes and small cleanups to ntfs_volume structure. -2.0.12: - - Internal cleanups in address space operations made possible by the - changes introduced in the previous release. -2.0.11: - - Internal updates and cleanups introducing the first step towards - fake inode based attribute i/o. -2.0.10: - - Microsoft says that the maximum number of inodes is 2^32 - 1. Update - the driver accordingly to only use 32-bits to store inode numbers on - 32-bit architectures. This improves the speed of the driver a little. -2.0.9: - - Change decompression engine to use a single buffer. This should not - affect performance except perhaps on the most heavy i/o on SMP - systems when accessing multiple compressed files from multiple - devices simultaneously. - - Minor updates and cleanups. -2.0.8: - - Remove now obsolete show_inodes and posix mount option(s). - - Restore show_sys_files mount option. - - Add new mount option case_sensitive, to determine if the driver - treats file names as case sensitive or not. - - Mostly drop support for short file names (for backwards compatibility - we only support accessing files via their short file name if one - exists). - - Fix dcache aliasing issues wrt short/long file names. - - Cleanups and minor fixes. -2.0.7: - - Just cleanups. -2.0.6: - - Major bugfix to make compatible with other kernel changes. This fixes - the hangs/oopses on umount. - - Locking cleanup in directory operations (remove BKL usage). -2.0.5: - - Major buffer overflow bug fix. - - Minor cleanups and updates for kernel 2.5.12. -2.0.4: - - Cleanups and updates for kernel 2.5.11. -2.0.3: - - Small bug fixes, cleanups, and performance improvements. -2.0.2: - - Use default fmask of 0177 so that files are no executable by default. - If you want owner executable files, just use fmask=0077. - - Update for kernel 2.5.9 but preserve backwards compatibility with - kernel 2.5.7. - - Minor bug fixes, cleanups, and updates. -2.0.1: - - Minor updates, primarily set the executable bit by default on files - so they can be executed. -2.0.0: - - Started ChangeLog. - |
