E2fsprogs 1.43 (May 17, 2016)
|
|
=============================
|
|
|
|
Add support for the ext4 metadata checksum, checksum seed, inline
|
|
data, encryption, project quota, and read-only features.
|
|
|
|
Support for the very old, experimental, and never-added-to-mainline
|
|
compression feature has been removed.
|
|
|
|
Mke2fs will now create file systems with the metadata_csum and 64bit
|
|
features enabled by default.
|
|
|
|
The mke2fs program will now support multiple -O options (instead of
|
|
just ignoring all but the last -O option).
|
|
|
|
Mke2fs will now correctly determine the size of a file system and
|
|
handle the discard operation correctly when the "-E offset=NNN" is
|
|
used. (Addresses Debian Bug: #803629)
|
|
|
|
The tune2fs program will ask the user for confirmation before starting
|
|
dangerous operations if the terminal is available, and it will replay
|
|
the journal if necessary.
|
|
|
|
Add an ext2/3/4 FUSE server
|
|
|
|
Debugfs can now modify extended attributes and journal transactions.
|
|
|
|
Debugfs now can properly display and set extended timestamps.
|
|
|
|
E2fsck will offer to fix extended timestamps that were incorrectly
|
|
encoded by older kernels.
|
|
|
|
Fix miscellaneous MMP bugs in debugfs.
|
|
|
|
Fix sparse_super2 bugs in mke2fs and resize2fs.
|
|
|
|
Fix or improve offset support in mke2fs, e2undo, and libext2fs.
|
|
|
|
The resize2fs command can now convert file systems between 64-bit and
|
|
32-bit mode.
|
|
|
|
Fix potential out-of-bounds memory access in resize2fs when doing a
|
|
large off-line file system grow operation.
|
|
|
|
We now use a new e2undo file format which is much more efficient and
|
|
faster than the old tdb-based scheme. Since it so much faster,
|
|
e2fsck, tune2fs, debugfs, and resize2fs now also can support using
|
|
creating an undo file.
|
|
|
|
The mke2fs command can now set the error behavior when initializing
|
|
the file system (so the administrator doesn't have to issue a separate
|
|
tune2fs -e command).
|
|
|
|
Teach mke2fs to parse a human-readable argument for -i option.
|
|
|
|
Teach mke2fs to automatically handle creating file systems > 500T by
|
|
automatically enable the meta_bg feature.
|
|
|
|
Mke2fs will now prompt for user verification before rewriting a file
|
|
system's superblock using the -S option.
|
|
|
|
Mke2fs no longer complains if the user tries to create a file system
|
|
using the entire block device (e.g., without using a partition). The
|
|
minor number convention is not used by all block devices, and it's
|
|
quite normal in some circumstances to create a file system on /dev/sdc
|
|
instead of /dev/sdc1.
|
|
|
|
Fix an "mke2fs -d" bug which could create inodes with invalid
|
|
extended attribute blocks
|
|
|
|
E2fsck is now much more paranoid about not freeing or corrupting
|
|
critical metadata blocks, such as inode table blocks, even if
|
|
corrupted indirect blocks or extent trees point at these blocks.
|
|
|
|
E2fsck now prints block ranges in pass1b instead of listing all of the
|
|
blocks exhaustively.
|
|
|
|
E2fsck will try to expand the root directory if the lost+found can't
|
|
be linked to the root directory. Also, offer to use the root
|
|
directory if lost+found can't be created.
|
|
|
|
E2fsck is now more paranoid handling corrupted extent trees as well as
|
|
corrupted journals.
|
|
|
|
E2fsck can now rebuild extent trees, either (a) to optimize them, (b)
|
|
to recover from a corrupted extent tree, or (c) to convert
|
|
block-mapped inodes to use extents.
|
|
|
|
E2fsck now has a readahead mechanism which can significantly speed its
|
|
performance, especially on RAID arrays.
|
|
|
|
E2fsck now has a "yes to all" option which the user can give if she is
|
|
tired of answering 'y' to a very large number of questions.
|
|
|
|
E2fsck will now ignore the badblocks inode if the contents of the
|
|
badblocks inode indicate that the portion inode table containing the
|
|
badblocks inode is bad. (We must go deeper...)
|
|
|
|
E2fsck can now correctly fix directory with holes on bigalloc file
|
|
systems.
|
|
|
|
E2fsck will now check for extent mapped inodes with no extent header
|
|
and clear them if found.
|
|
|
|
E2fsck now checks to make sure the extended attribute header doesn't
|
|
result in the xattr extending beyond the bounds of the inode
|
|
|
|
Fixed a bug in e2fsck to avoid overrunning a buffer containing jbd2
|
|
revoke records if the journal is corrupted.
|
|
|
|
Fixed a bug in e2fsck which could cause it loop forever if a special
|
|
inode has too many invalid block mappings.
|
|
|
|
Fixed a bug in e2fsck which could cause pass1b/c/d processing to get
|
|
confused if an attempt to allocate a block can't find any free space
|
|
in the file system.
|
|
|
|
E2fsck will no longer try to force rewrite blocks located beyond the
|
|
file system.
|
|
|
|
The e2fsck program will no longer update the quota inodes when it is
|
|
interrupted.
|
|
|
|
Fix a bug which in rare cases would cause e2fsck -fD to corrupt an
|
|
extent-mapped directory.
|
|
|
|
Fixed a bug in resize2fs which could lead to resize2fs crashing or a
|
|
corrupted file system if the file system is almost completely full
|
|
when trying grow a file system and we need to allocate blocks to grow
|
|
the block group descriptors.
|
|
|
|
Fixed a bug in resize2fs which could cause it to get fooled trying to
|
|
determine the RAID array's stride when flex_bg is enabled.
|
|
|
|
Fix resize2fs bug that could leave block allocation bitmaps
|
|
uninitialized.
|
|
|
|
The dumpe2fs output has been improved so it is cleaner and always fits
|
|
within 80 columns. Also added a more easily machine-parsable output
|
|
of dumpe2fs.
|
|
|
|
The mke2fs program can now pre-populate a file system from a directory
|
|
hierarchy using the -d option.
|
|
|
|
The mke2fs program now skips zeroing inode table blocks if they were
|
|
already zeroed using the discard feature.
|
|
|
|
Check to make sure file system features which can not be supported by
|
|
HURD are not enabled if the file system is created to be
|
|
HURD-compatible.
|
|
|
|
Added a new e2fuzz command that will fuzz an ext4 image for testing
|
|
purposes.
|
|
|
|
The debugfs logdump command can now deal with 64-bit revoke tables
|
|
correctly. Also, "logdump -O" will print the old log contents (before
|
|
the journal was replayed).
|
|
|
|
The debugfs bmap command can now be used to set or allocate a physical
|
|
block.
|
|
|
|
Fixed a bug so "filefrag -B -e -v" does not return a separate entry
|
|
for each block.
|
|
|
|
The filefrag program now accounts for holes in sparse files created by
|
|
the file punch operation as an expected/optimal mapping.
|
|
|
|
The file I/O functions now correctly handle inodes containing
|
|
uninitialized blocks.
|
|
|
|
Fix a bug in tune2fs so that removing uninit_bg feature on a bigalloc
|
|
file system won't result in corrupted block bitmaps.
|
|
|
|
Updated/fixed various man pages. (Addresses Debian Bug: #798425)
|
|
|

Programmer's Notes
|
|
------------------
|
|
|
|
Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
|
|
|
|
Added Android build files so that e2fsprogs can be built in the
|
|
Android source tree.
|
|
|
|
Reduce the use of libc functions in libext2fs that may not be present
|
|
in the boot loader environment, at least for those functions that are
|
|
needed by boot loaders such as yaboot.
|
|
|
|
Developers can now override the debugging and optimization flags by
|
|
redefining the CFLAGS makefile macro.
|
|
|
|
The libext2fs library now has support for fallocate.
|
|
|
|
The mke2fs command will now ask the user for confirmation if block
|
|
device or image file contains an existing file system image, and
|
|
stdout and stdin are connected to a tty.
|
|
|
|
The libext2fs library now picks a more intelligent goal block when
|
|
doing block allocations.
|
|
|
|
The libext2fs library will now automatically set the BLOCK_UNINT flag
|
|
if all of the blocks in a block group are free, to speed up future
|
|
e2fsck and dumpe2fs operations on the file system.
|
|
|
|
Add two new functions ext2fs_new_range() and ext2fs_alloc_range() to
|
|
libext2fs.
|
|
|
|
The ext2fs_zero_blocks() command will use FALLOC_FL_ZERO_RANGE for
|
|
file-based images.
|
|
|
|
The ext2fs_bmap() function supports new flags BMAP_UNINIT and
|
|
BMAP_ZERO.
|
|
|
|
The ext2fs_new_block2() function will now call the alloc_block hook
|
|
before checking fs->block_map.
|
|
|
|
Support for the MMP feature can now be disabled at compile time.
|
|
|
|
Added support to manipulate extended attributes to libext2fs.
|
|
|
|
Added a lot of new regression tests.
|
|
|
|
Added endian annotations so it's possible to scan e2fsprogs for endian
|
|
problems using a static code analyzer.
|
|
|
|
Fixed memory leaks in libext2fs.
|
|
|
|
The e2fsck jbd2 handling code has been resynced with the 3.16 kernel.
|
|
There is now a script in the contrib directory which automates most of
|
|
the resync process.
|
|
|
|
The build system will now run cppcheck (a static code analysis tool)
|
|
via "make C=1"
