E2fsprogs 1.44.0 (March 7, 2018)
|
|
================================
|
|
|
|
Updates/Fixes since v1.43.9:
|
|
|
|
UI and Features
|
|
---------------
|
|
|
|
E2fsprogs now supports the large_dir (INCOMPAT_LARGEDIR) feature. This
|
|
feature allows larger directories to be created, both with directory
|
|
sizes over 2GB and and a maximum htree depth of 3 instead of the
|
|
current limit of 2. These features are needed in order to exceed
|
|
the currently limit of approximately 10M entries in a single
|
|
directory for 4KB blocksize (~100k for 1KB).
|
|
|
|
E2fsprogs now supports the ea_inode (INCOMPAT_EA_INODE) feature, which
|
|
stores large extended attributes in an external inode instead of a
|
|
single data block. This is backwards compatible with a Lustre file
|
|
system feature, but it has been extended to support deduplicating
|
|
extended attribute values which are used in multiple inodes.
|
|
|
|
The metadata_csum feature (RO_COMPAT_METADATA_CSUM) is now enabled by
|
|
default by mke2fs.
|
|
|
|
The resize2fs program will no longer complain about resizing bigalloc
|
|
file systems as being dangerous when doing an on-line resize (since this
|
|
is purely a kernel feature).
|
|
|
|
Debugfs's ls command will now print the high bits of the inode's mode
|
|
bits.
|
|
|
|
Fixes
|
|
-----
|
|
|
|
Fixed some potential buffer overrun bugs in the blkid library and in the
|
|
fsck program.
|
|
|
|
There were some corner cases which tune2fs wouldn't correctly handle
|
|
when operating on a file system which was not cleanly mounted and thus
|
|
required running the journal because it could be modified. Tune2fs will
|
|
now run the journal before trying to change the superblock, and if the
|
|
file system needs to be checked after the journal has been replayed, it
|
|
will require it before proceeding. Also if the file system is busy (for
|
|
example, because it is in use by Lustre), but is not present in the
|
|
/proc/mounts or /etc/mtab, tune2fs will not try to replay the journal,
|
|
since this could do real damage if it the file system is being actively
|
|
modified by the kernel.
|
|
|
|
The libss library (used by debugfs) now supports the version 7 of the
|
|
libreadline shared library.
|
|
|
|
The e2freefrag program will use the GETFSMAP ioctl if it is available
|
|
and the file system is mounted, so that the free space statistics will
|
|
be more accurate.
|
|
|
|
The consistency checks for symlinks (especially for encrypted and inline
|
|
data file sytems) in e2fsck are now much more careful/stringent. Also
|
|
fixed a bug where creating a symlink using ext2fs_symlink() which was
|
|
exactly 60 bytes long when inline data was enabled would result in a
|
|
missing system.data xattr.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
--------------------------------------------------------------
|
|
|
|
Mke2fs now uses io_channel_flush() instead of sync() for the sync_kludge
|
|
feature.
|
|
|
|
E2fsprogs now uses i_size as the primary way of determining whether a
|
|
symlink is a fast symlink.
|
|
|
|
Fix various compiler and UBSAN warnings.
|
|
|
|
Long running test are now skipped with "make check" and only run when
|
|
"make fullcheck". The test runner will warn when potentially long
|
|
running tests are being run via "make check".
|
|
|
|
E2fsck is now much faster for bigalloc file systems when scanning
|
|
extents for bigalloc file systems. (Addresses Google Bug #36886699)
|
|
|
|
Update Czech, Spanish, French, Malay, and Ukrainian translations.
