Please consider pulling fs-verity for 5.4.
fs-verity is a filesystem feature that provides Merkle tree based
hashing (similar to dm-verity) for individual readonly files, mainly for
the purpose of efficient authenticity verification.
This pull request includes:
(a) The fs/verity/ support layer and documentation.
(b) fs-verity support for ext4 and f2fs.
Compared to the original fs-verity patchset from last year, the UAPI to
enable fs-verity on a file has been greatly simplified. Lots of other
things were cleaned up too.
fs-verity is planned to be used by two different projects on Android;
most of the userspace code is in place already. Another userspace tool
("fsverity-utils"), and xfstests, are also available. e2fsprogs and
f2fs-tools already have fs-verity support. Other people have shown
interest in using fs-verity too.
I've tested this on ext4 and f2fs with xfstests, both the existing tests
and the new fs-verity tests. This has also been in linux-next since
July 30 with no reported issues except a couple minor ones I found
myself and folded in fixes for.
Ted and I will be co-maintaining fs-verity.
