E2fsprogs 1.44.4 (August 18, 2018)

UI and Features

Add basic support for the ext4 verity feature (aka fsverity). It is a read-only compatibility feature which uses Merkle trees to add functionality much like dm-verity on a per-file basis. For this release we simply allow e2fsck to accept file systems with the verity feature enable (no special handling is needed) and mke2fs to create file systems with the verity feature.

Fixes

E2fsck will now properly repair a file system that has both the resize_inode and meta_bg features enabled simultaneously (which is never supposed to happen, but it could happen in versions of mke2fs before 1.44.3 when it was given parameters where more than 75% of the block group was used for group descriptor tables).

Avoid a floating point exception crash when libblkid tries probing a maliciously corrupted HFS+ superblock.

Debugfs's ncheck command now properly will handle inodes that have multiple hard links.

On platforms that don't supply strdup, the replacement function for strdup() had a bug which would cause it to crash if it was used. (Fortunately this only happens if the [scratch_files] feature in e2fsck is used.)

Fixed support for devices which have non-512 byte block sizes on Apple Darwin.

E2fsprogs 1.44.3 would fail to compile on very old versions of gcc. This is now fixed.

Update and clarify man pages.

Performance, Internal Implementation, Development Support etc.

Synchronized changes from Android's AOSP e2fsprogs tree.

Instead of building the subset e2fsprogs-libs tar file, add a new configure option, --enable-subset. This along with other changes (such as dropping obsolete files that aren't shipped as part of e2fsprogs-X.YY.tar.gz) allows us to be able to build the tarball using the "git archive" command.
