ntfsfallocate is the equivalent of fallocate(1) :
Usage : ntfsfallocate [-n] [-p] [-o offset] -l length filename
For now, it is only released as a quarantined ntfsprogs because it can
produce configurations which cause subsequent updates of the file by
Windows to hang.
Distributions have complained about releasing a non-functional ntfsck.
Actually, ntfsck and a few other developer-oriented utilities were not
meant to be released by distributions and are only compiled in if the
configure option --enable-extra is set, and, for some reason, this
option is set by most distributions.
In order to get distributions to not complain, though making the source
code available for candidate developers to improve it, the non functional
or developer-oriented utilities (ntfsck, ntfsdump_logfile, ntfsmftalloc
and ntfsmove) are now only compiled in if the configure option
--enable-quarantined is set.
The ntfsprogs used to return failure when option --version or --help
was used, and this has triggered complains from distribution packagers
who use these options in packaging scripts.
With this patch, success is returned (same behavior as gcc).
When the partition is resized, the global bitmap size is adjusted accordingly,
however so far the new size was not set into the parent index (only minor
consequences).
The ioctl() function is not implemented in the Windows variant. By forcing
a negative apparent return, an alternative is triggered to get the
partition size which is normally obtained from an ioctl().
In some rare situations relocated runlists are longer than the original
ones and do not fit into the same extent. When this happens the runlist
updating is delayed and done globally. Be sure to use the updated global
bitmap for making the needed allocations.
X509 certificates have a purpose field restricting what the certificate
can be used for, and EFS encryption is such a purpose. Allow EFS encryption
to be at any position in the list.
When ntfsclone'ing to a file, the target file was truncated to the volume
size. This is not useful on file systems which support sparse files. In
the case of ntfs-3g this leads to prevent optimizations specific to
appending data. So when a sparse output file is detected, it is emptied
to benefit from subsequent appending of data.
The upcoming libgrypt-1.6 drops the "module" interface which was used
by ntfsdecrypt for decrypting files which were encrypted with the "DESX"
algorithm. This algorithm is a Microsoft variant of DES with a key size
of 128 bits, and is not natively supported by libgrypt. The module interface
made possible to declare an external algorithm so that all the encryption
modes could be processed the same way whether the algorithm was internal
or external.
This patch makes DESX a specific case, so that the module interface is
not needed any more. It is compatible with current libgrypt and upcoming
libgrypt-1.6
When trying to undelete a file which was modified several times the
same day, it is difficult to tell which one is the latest unless the
modification time is displayed.
Traditionally the backup boot sector is not set by ntfsresize because
the exact partition size is not yet known. A chkdsk is triggered to
subsequently insert it.
However ntfsresize is frequently activated by a partition editor which
has an exact knowledge of the wanted layout, and the backup boot sector
can be inserted by ntfsresize. This is only done if the target partition
size is defined with no unit suffix, and it is a multiple of the sector
size. Anyway the backup boot sector cannot overwrite useful data as it
is inserted between the file system size and the target partition size.
The usa sequence is used to make sure the sectors containing metadata
are fully written. The values are always put at the end of 512-byte
chunks even if the sectors are greater.
When the MFT is partially located beyond the end of a resized partition,
it has to be relocated after the other files have been processed
because the MFT data is needed to do the relocations. When the MFT runlist
is split over extents, all of them have to be processed.
When the beginning of the MFT is beyond the end of the resized
partition, a specific procedure has to be used to relocate this part
of the MFT and adjust the bitmap accordingly. On a test run, these
updates should not be done.
The long long printing formats (such as %lld or %llx) have to be
translated to %I64 on older Windows systems, and the buffers to
receive the translated format must be able to hold the tool banners
which can be quite lengthy.
The size argument of ntfsresize is the target partition size. This is
not the file system size as returned by df(1) or statvfs(3) because a
sector is reserved for the backup boot sector, and the remaining sector
count might not be a multiple of clusters per sector.
When a sector is unreadable, consider the whole sector as bad, instead
of trying to find which 512-byte parts of it are bad. This was causing
unwanted retries for devices with 4K sectors.
Older msvcrt.dll (on XP and earlier) did not support "%ll" print editing
formats frequently used by ntfsclone. So translate them to "%I64" when
running on Windows. This format appears to be supported by all Windows
versions. Error messages from libntfs-3g are still not translated.
This mainly means using the functions in win32_io.c instead of the
standard msvcrt.dll ones in order to be able to truncate files and
create sparse ones.
