Since Windows 8 a new stream is added to the upper case file to record
a CRC of the upper case data. This way, if the file does not match the
one defined on the current Windows system, chkdsk can tell whether the
file is damaged or just out of date, and an error is only displayed if
the file is damaged.
The $Info data has been checked to be ignored by Windows XP, Windows
Vista and Windows 7. If not present, chkdsk for Windows 8 complains about
a wrong upper case file.
The named attributes sizes were wrongly computed in mkntfs. This did not
lead to visible errors so far owing to 8-byte alignments in attribute
records (current names $SDS, $R, $O, etc).
Appending data to a file is done in two steps : first extending the
file to the required size, then inserting data in the created space.
There is no need to recompute the runlist at the end of the first
step, just be sure the original configuration is rolled back if inserting
data leads to an error.
Special files (FIFOs, SOCKETs, etc.) are not allowed to have user extended
attributes. When listing their extended attributes, return none without
checking whether the calling process is allowed to access these files.
ntfsfix now checks and update the backup boot sector on the last sector of
the partition (instead of the sector next to end of the file system). After
an ntfsresize the file system generally does not use the maximum size because
of different roundings and required alignments in the resizing and the
repartitioning.
When the target of a junction or a Windows-type symlink references another
junction or symlink, the search for the full path on the current partition
and its translation for case-sensitive access is interrupted. The target can
now be dereferenced, provided the end of the path needed no translation.
So far the set-group-id flag could be set in a chmod. This patch enables
the inheritance of the group to files and subdirectories, and the
inheritance of the set-group-id flag to subdirectories.
The suggestion to use option remove_hiberfile was displayed in the
standard help and when a volume is found dirty. As this option may
lead to loss of data, only mention it in the manual, with a proper
warning.
The option delay_mtime avoid updating the mtime of a file after each
individual updating. With this patch, the frequency of the update can
be adjusted to needs (default 60s). This is mainly useful for big files
which are kept open for a long period (file system images, virtual
computers, etc.)
Under some conditions, Windows defines an ACL inheritance for an
unidentified authenticated user. With this patch, such an unidentified
user is treated as any user (same as "world").
UTIME_NOW and UTIME_OMIT are needed for implementing utimensat() and
futimens(2), but they cannot yet be used with external fuse.
This patch is to avoid errors if they cannot be used, even with fuse 4.9
When the hide_dot_files option is set, a file is marked hidden if the
first character in its name is a dot. This patch updates the hidden flag
when the file is renamed or hard linked (useful for text editors which
create files with a temporary name)
When a file is deleted, there is no need to remove its last name in
the deleted MFT record. The name may be useful for undeleting the file
later (Windows also does not delete the name).
The special tests for accepting ftruncate(2) and access(W_OK) applied
to a file being created read-only have been implemented in the fuse
kernel module, so there is no need to duplicate them in the file system.
On OpenIndiana the fuse kernel module does not prevent unlink(2)
from deleting directories, nor prevent rmdir(2) from deleting files,
so this has to be done in the lowntfs-3g driver.
Checking supplementary groups permissions to access a file relies on
a supplementary group list available in /proc/PID. This patch adds a
variant to implement the checks based on the specific format used
by OpenIndiana.
Defined new options --new-serial and --new-half-serial to set a new
serial number (either the given one or a random one) to a file system.
Useful for mounting the original and the cloned file system at the
same time.
Defined new options --new-serial and --new-half-serial to set a new
random serial number when cloning or restoring a file system.
Useful for mounting the original and the cloned file system at the
same time.
Clearing of user data was wrong when extracting the metadata into a
special format image. In this situation the clearing has to be done
without mounting the file system.
When a file is created with no write permissions, ftruncate and
access(W_OK) should be allowed, but this check has to be made by the
file system on OpenIndiana.
This patch is not active on Linux (#ifdef'ed)
When a user queries an extended attribute in the trusted namespace,
the traditional error return was EPERM. This has been recently changed
to ENODATA. See https://lkml.org/lkml/2011/5/27/199
On Windows XP and Vista, the system hibernation is identified by the
sequence "hibr" at the beginning of hiberfil.sys. This had been changed
to "HIBR" in Windows 7, so both sequences have to be accepted as
hibernation criteria.
When extracting the metadata, unused data at the end of MFT records is
supposed to be cleared. This was done for the base record of each file,
but not for the extent records.
