E2fsprogs 1.46.6 (September 12, 2022)
|
|
=====================================
|
|
|
|
Updates/Fixes since v1.46.5:
|
|
|
|
UI and Features
|
|
---------------
|
|
|
|
Debugfs's ncheck command now allows the inode number to be surrounded by
|
|
angle brackets, to be consistent with other debugfs commands.
|
|
|
|
Debugfs no longer prints a scary message when debugfs -c (which enables
|
|
"catastrophic mode") is used. This was intended to allow debugfs to
|
|
operate on very badly corrupted file systems, but it is now sometimes
|
|
used to suppress reading the block and inode bitmaps when they are not
|
|
needed.
|
|
|
|
Resize2fs will round down the requested new file system size to the
|
|
nearest cluster boundary when resizing bigalloc file systems.
|
|
|
|
Improve error messages issued by badblocks.
|
|
|
|
Fuse2fs now supports an offset=<bytes> option which allows operating on
|
|
a file system image which is located starting at the specified offset
|
|
from the beginning of the image.
|
|
|
|
|
|
|
|
Fixes
|
|
-----
|
|
|
|
Pre-v6.2 Linux kernels had long-standing bug in how the extended
|
|
attribute hash was calculated when there were non-ASCII characters in
|
|
the xattr name, when the hash would be different depending on whether
|
|
the C 'char' type was signed or unsigned. To address this bug, starting
|
|
with e2fsprogs 1.46.6+ and Linux 6.2+, we will accept either the signed
|
|
or unsigned hash variant, but only set the unsigned hash variant. Since
|
|
extended attribute names are in practice composed of ASCII characters,
|
|
other than various tests (such as generic/454), most users will
|
|
hopefully not notice this change.
|
|
|
|
Avoid triggering udev in dumpe2fs and "resize2fs -P" for file systems
|
|
with MMP enabled by opening the device read-only when reading the MMP
|
|
block.
|
|
|
|
Fix MMP handling so it can notice when another writer has modify the MMP
|
|
block out from under it when stopping a MMP sessions.
|
|
|
|
Fix tune2fs so it will detect another device stealing the MMP sessions
|
|
while rewriting metadata checksums.
|
|
|
|
E2fsck will now check to make sure the journal inode does not have the
|
|
encrypt flag set.
|
|
|
|
Fix a deadlock bug in e2fsck's error handler when there are errors
|
|
trying to write to the file system.
|
|
|
|
Fix a bug where e2fsck could fail when specifying an undo file and an
|
|
explicit superblock number.
|
|
|
|
Fix e2image so it won't potentially loop forever for certain invalid
|
|
file systems.
|
|
|
|
Fix resize2fs to honor the E2FSPROGS_FAKE_TIME environment variable.
|
|
This allows embedded system builders who use resize2fs as part of their
|
|
image build process to create reproducible images.
|
|
|
|
Fix tune2fs to avoid a crash if the journal replay fails and to make
|
|
sure its exit status is non-zero if there is some failure.
|
|
|
|
Fix tune2fs, fuse2fs, and debugsfs to update j_tail_sequence when
|
|
replaying the journal.
|
|
|
|
Add additional bullet-proofing for very badly corrupted file systems.
|
|
Try avoid UBSAN warnings, null pointer derferences, and other memory
|
|
bugs. (Addresses CVE-2022-1304)
|
|
|
|
Don't fail when the source directory for mke2fs -d doesn't support
|
|
extended attributese.
|
|
|
|
Check for and handle malloc() failures when computing the log filename
|
|
in e2fsck and in the libss library.
|
|
|
|
Fix tune2fs and e2fsck to accept pathames which include '=' characters.
|
|
Previously arguments to tune2fs and e2fsck which included '=' characters
|
|
are presumed to be blkid specifiers such as UUID=xxx or LABEL=yyy. If a
|
|
specifier is both a valid pathname name and blkid tag name specifier,
|
|
priority is given to a blkid resolved pathname.
|
|
|
|
Improve tune2fs's error messages.
|
|
|
|
Fix a bug in tune2fs which could cause it to crash if device goes
|
|
off-line just as it being opened.
|
|
|
|
Fix the fsck driver so if it is interrupted while running fsck -N it
|
|
doesn't end up kllling all processes on the system.
|
|
|
|
Fix a crash in badblocks when the user specifies an overly large
|
|
number of blocks tested at a time in read/write or nondestructive
|
|
mode.
|
|
|
|
Update and clarify's chattr's man page and usage message. Fix spelling
|
|
typo's in a variety of different man pages and comments.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
--------------------------------------------------------------
|
|
|
|
Update to autoconf 2.71.
|
|
|
|
Update flags used to create shared library on Darwin/MacOS.
|
|
|
|
Speed up e2fsck's clonning of multiply-claimed blocks so it is
|
|
substantially faster on very large file systems.
|
|
|
|
Add tests/fuzz directory with fuzzers from oss-fuzz.
|
|
|
|
Add a Github Actions configuration file so that Github will run CI tests
|
|
on Linux, Windows and MacOS on a push to the e2fsprogs github repo.
|
|
|
|
Make the mtab parsing in ext2fs_check_mount_point() more careful so it
|
|
won't get confused when a block device shows up in the mnt_name field
|
|
for a virtual file system.
|
|
|
|
Fix the libss's Makefile to create the man page directory before trying
|
|
to install its man page.
|
|
|
|
Fix various Coverity and compiler warnings.
|
|
|
|
Make tests more portable on various different OS's and system
|
|
configurations (e.g., with SELinux enabled, MacOS, and Windows)
|
|
|
|
Use mallinfo2() instead of mallinfo() where avilable, since mallinfo()
|
|
is deprecated on newer glibc versions.
|
|
|
|
E2fsck will no longer do a full scan of disconnected directory when
|
|
trying to print the parent directory, which is pointless and can slow
|
|
down e2fsck if there are a large number of disconnected directories.
|
|
|
|
Debugfs will now print the extended attribute's e_hash field.
|
|
|
|
Fix the setup-schroot script to work on non-Linux platforms.
|
|
|
|
Fix ext2fs_compare_generic_bmap() so it correctly compares all of the
|
|
bits in the bitmap, and so that it works correctly when comparing a
|
|
bitarray bitmap with a rbtree-based bitmap. (Fortunately, none of the
|
|
programs in e2fsprogs uses bitmap comparison functions.)
|
|
|
|
Fix memory leaks on error paths.
|
|
|
|
Add support for the configure option --enable-largefile so that
|
|
e2fsprogs can utilize largefile support for the MUSL C library.
|
|
|
|
Add an note that the dict library code has been modified, as required by
|
|
the Kazlib license.
|
|
|
|
Synchronized changes from Android's AOSP e2fsprogs tree.
|
|
|
|
Updated config.guess and config.sub with newer versions from the FSF.
|
|
|
|
Add Friulian translation.
|
|
|
|
Update Chinese, Czech, Dutch, French, German, Malay, Polish, Serbian,
|
|
Spanish, Swedish, and Ukrainian translations.
