Changelog
e2fsprogs (1.46.0-1) experimental; urgency=medium
* New upstream release
* Add support for the new fast_commit feature. (Requires Linux version
5.10 or higher)
* Add support for the new stable_inodes feature which is needed to
support some file system encryption algorithms such as siphash.
* Add support for file systems that have both case folding and
encryption enabled. (Requires Linux version 5.10 or higher)
* The fuse2fs program now supports the "norecovery" which omits replying
the journal and mounts the file system read-only.
* Bitmap loading is now done using multiple threads which can speed up
debugfs, dumpe2fs, and e2fsck on very large file systems.
* E2fsck now will check file names on file systems with case folding
enabled to make sure the characters are valid UTF-8 characters.
This is done for file systems which enforce strict encodings, and
optionally if the extended "check_encoding" option is requested.
* E2fsck will properly handle checking for duplicated file names when
case folding is enabled.
* E2fsck will now find and fix file system corruptions when the encrypted
files have a different policy from their containing directory.
* The "htree" command in debugfs now displays the metadata checksums for
hash tree index blocks.
* Fix various bugs where a maliciously corrupted file systems could case
e2fsck and other e2fsprogs programs to crash.
* Dumpe2fs will print the error code that Linux kernels newer than v5.6
will save to indicate the class of error which triggered the ext4_error
event.
* E2fsprogs programs (in particular, fuse2fs) can now update htree
directories without clearing the htree index.
* Tune2fs will properly recalculate directory block checksums when
clearing the dir_index feature.
* Fix a bug in e2fsck directory rehashing which could fail with ENOSPC
because it doesn't take into account the space needed for the metadata
checksum, and doesn't create a sufficiently deep index tree.
* Clarify the e2fsck messages when it resets the directory link count when
it is set to the overflow value but it is no longer needed.
* Mke2fs now sets the s_overhead_cluster field, so that the kernel doesn't
need to calculate it at mount time. This speeds up mounting very large
file systems.
* Speed up mke2fs when creating large bigalloc file systems by optimizing
ext2fs_convert_subcluster_bitmap().
* The filefrag program can now request the kernel to display the extent
status cache by using "filefrag -E". (This requires Linux version 5.4
or newer.)
