fscrypt: support decrypting data from large folios (2023-01-28 15:10:12 -0800)
----------------------------------------------------------------
Fix the longstanding implementation limitation that fsverity was only
supported when the Merkle tree block size, filesystem block size, and
PAGE_SIZE were all equal. Specifically, add support for Merkle tree
block sizes less than PAGE_SIZE, and make ext4 support fsverity on
filesystems where the filesystem block size is less than PAGE_SIZE.
Effectively, this means that fsverity can now be used on systems with
non-4K pages, at least on ext4. These changes have been tested using
the verity group of xfstests, newly updated to cover the new code paths.
Also update fs/verity/ to support verifying data from large folios.
There's also a similar patch for fs/crypto/, to support decrypting data
from large folios, which I'm including in this pull request to avoid a
merge conflict between the fscrypt and fsverity branches.
There will be a merge conflict in fs/buffer.c with some of the foliation
work in the mm tree. Please use the merge resolution from linux-next.
----------------------------------------------------------------
Eric Biggers (19):
fsverity: optimize fsverity_file_open() on non-verity files
