When ignore_case is set, the file names are returned lower-case in
readdir() in order to make file name completions possible. This patch
does the same for junction points to avoid directory locks when used
with non-matching names.
When the normal boot sector is not usable, ntfsfix tries to use the last
sector as a boot sector replacement. This implies getting the sector size
and reading both full-sized boot sectors.
When creating a partition image, ntfsclone write an extra byte to
describe each cluster, this causes two unneeded ntfs-3g calls per cluster,
and inefficiency when imaging to ntfs.
In rare situations there is not enough space in the base inode entry
to make an index non resident. The index has to be moved to an extent
first. This happens when not using permissions and inserting a file
whose name has 60 chars into a directory whose name has 184 chars.
(bug reported by Vito Caputo)
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.
The recorded allocated size depends on unnamed data being non resident,
which depends on MFT record size, hence on sector size.
The allocated size was wrong for $AttrDef when sector size is 4K bytes
(chkdsk silently fixes it).
A corner case was wrong and could cause aborted writes with error
"Run lists overlap. Cannot merge" when the clusters required by the
write are described in different MFT extents.
This can only happen in very fragmented files when the cluster size
is smaller than 4096 bytes. It does not cause any metadata corruption.
A recent patch added copying the backup boot sector when cloning,
saving or restoring a partition, but when the total number of sectors is
not a multiple of the number of sectors per cluster, the last cluster
containing the backup boot sector is shorter than usual.
When this happens, the present patch avoids overflowing from partition
when accessing the last cluster.
