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*'.
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.
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__
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 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.)
With the default mount options, compression of new files are now done
if the parent directory is marked for compression. The mount option
"compression" is not needed any more, but the option "nocompression"
can be used to disable compression of new files.
The default option also applies to applications using libntfs-3g with
no mount command.
Logging of fixup errors for uninitialized inodes cause unnecessary
worries and suspicion of malfunctions in ntfs-3g. This patch silences
these loggings in ntfsclone and ntfsresize which have to analyze all
inodes, including the uninitialized ones.
The label changing code in ntfslabel was cleaned up and modified to use the more
advanced functionality of libntfs-3g instead of using older custom code to
resize and create resident attributes.
The core label changing functionality was also moved into the library so it can
be reused by other programs.
For some reason, when the monted device is "/dev/mapper/*", a record
in the form "/dev/dm-*" ends up in /etc/mtab and the device cannot be
unmounted.
The reason is unclear, the /dev/mapper name is not a symlink, and the
function doing the name change is not known. No detailed feedback from
the users having met the issue.
The patch changes the name back to the /dev/mapper name after realpath()
is called, and, if there is an actual change, both the name passed to
ntfs-3g and the one passed to fuse and mount are logged in the hope
of getting a clue about what is happening.
But ntfs-3g is probably not the right place for a fix.
The "flags" argument of ntfs_initialize_file_security() is intended to
feed the one to ntfs_mount(). Having the same type for both may avoid
future problems.
