The MS_* flags originated from system constants. However the flags
passed to ntfs_mount were really unrelated to the system constants and
many new MS_* flags had to be introduced as different features were
added to the library. Those flags had no counterparts in any system
APIs, so using the same naming scheme is inappropriate.
Instead, let's namespace these flags similarly to what has already been
done in ntfsprogs/libntfs earlier. This avoids any possible conflicts
with system constants.
The values of the flags themselves are kept the same as earlier, so
backward compatibility is retained.
- Replaced 'ntfschar*' parameters with 'const ntfschar*' where
appropriate (the function does not need to modify the string).
- Replaced some instances of 'u8*' and 'char*' read-only buffer
arguments with 'const u8*' and 'const char*'.
The 'uuid' library functionality may be located in a separate 'uuid'
library, but it may also be included in the standard C library. This is
the case on Mac OS X.
Instead of relying on the uuid code being located in a 'uuid' library,
we restructure the code so that it checks different libraries, in order
for the 'uuid_generate' function. This code is easy to extend if we
would find a new configuration where uuid_generate is located in a
different library.
The OpenSolaris port of libfuse, from which our Solaris-port of
libfuse-lite originated, had to be supplied with some additional
compiler flags in order to compile.
The configure script now detects whether it is running on a Solaris
system. If that is the case it passes the proper compiler flags to
libfuse-lite, so it can compile properly.
Tested on:
- OpenIndiana oi_151a3 / gcc 3.4.3
- OpenIndiana oi_151a7 / gcc 4.3.3
- Solaris 11.1 / gcc 4.5.2
When we aren't building ntfs-3g but only the tools, then there's no need
for libfuse. Still the configure script checked for libfuse availability
and wouln't proceed unless either libfuse was detected or libfuse-lite
was enabled.
This commit fixes this issue by running the libfuse checks only when
ntfs-3g is built, meaning that we can now build the ntfsprogs even when
libfuse library or headers aren't available.
Replace the obsolete definition of reparse tags in layout.h by the
current definitions from msdn, and use them in reparse.c instead of
redefining them.
As the path passed to ntfs-3g for getxattr(2)/setxattr(2) are not
guaranteed to be the one mentioned by the caller when there are hard links,
getting/setting DOS names have to be discontinued in that situation.
Getting/setting DOS names is still possible when there is a single
non-DOS name.
Windows 8 includes a "fast restart" feature for restarting without fully
remounting the internal volumes. When this mode is selected, metadata
stored in the cache (probably hiberfil.sys) is used instead of what
is actually on disk, and this may lead to inconsistencies when changes
have been made by ntfs-3g in the meantime.
This patch tries to prevent ntfs-3g from mounting in read-write mode
when a fast restart of Windows 8 is detected. It relies on the restart
pages in the $LogFile being identified as version 2.0, which is
apparently related to data being cached for hibernation or fast restarting.
External devices, such as USB keys, may have a switch to make them
temporarily unwriteable. When such a device is plugged in, mount it
as read-only by default.
In the $LogFile, Windows 8 defines restart pages with version 2.0.
The checks designed for version 1.1 appear to apply, so accept v 2.0
and apply the usual checks.
Accept security descriptors in which the SACL is present though it does not
contain any ACE. Such security descriptors have been found in Windows
installation files.
Get a user mapping proposal by designating a file created on Windows
by the user to be mapped to the current one on Linux.
This is expected to be easier to use than "usermap".
The variable 'flags' was modified along the way and did not contain the
original flags at the end as assumed by the last printout. Fixed by
storing the original state of the flags in a temporary const variable.
On OpenIndiana, the device names have commas in them. Do not interpret
commas as option separators within the option fsname. As a consequence
this option has to be the last one.
The libfuse used by OpenIndiana has the same features as libfuse-lite
though requiring some code variants. Merging them simplifies supporting
both.
Variants for OpenIndiana are selected when defining __SOLARIS__
The type of special files (symlinks, fifos, etc.) was not returned in
readdir() and they appeared wrongly in the field d_type of "struct dirent".
This prevented some applications which relied on d_type (which does
not exist in Solaris) from navigating in an NTFS tree.
Use of UTIME_NOW and UTIME_OMIT had been temporarily removed when using
external fuse, because early versions of external fuse 2.9 did not
support them. They can now be restored as they are supported by released
versions of fuse 2.9
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).
