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.
