Thank you!
The following changes since commit 88603b6dc419445847923fcb7fe5080067a30f98: Linux 6.2-rc2 (2023-01-01 13:53:16 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/fs/fsverity/linux.git tags/fsverity-for-linus for you to fetch changes up to 51e4e3153ebc32d3280d5d17418ae6f1a44f1ec1: 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 fsverity: optimize fsverity_prepare_setattr() on non-verity files fsverity: optimize fsverity_cleanup_inode() on non-verity files fsverity: pass pos and size to ->write_merkle_tree_block fsverity: remove debug messages and CONFIG_FS_VERITY_DEBUG fsverity: use unsigned long for level_start fsverity: simplify Merkle tree readahead size calculation fsverity: store log2(digest_size) precomputed fsverity: use EFBIG for file too large to enable verity fsverity: replace fsverity_hash_page() with fsverity_hash_block() fsverity: support verification with tree block size < PAGE_SIZE fsverity: support enabling with tree block size < PAGE_SIZE ext4: simplify ext4_readpage_limit() f2fs: simplify f2fs_readpage_limit() fs/buffer.c: support fsverity in block_read_full_folio() ext4: allow verity with fs block size < PAGE_SIZE fsverity.rst: update git repo URL for fsverity-utils fsverity: support verifying data from large folios fscrypt: support decrypting data from large folios Documentation/filesystems/fscrypt.rst | 4 +- Documentation/filesystems/fsverity.rst | 96 +++++---- fs/btrfs/verity.c | 19 +- fs/buffer.c | 72 +++++-- fs/crypto/bio.c | 10 +- fs/crypto/crypto.c | 28 +-- fs/ext4/inode.c | 6 +- fs/ext4/readpage.c | 3 +- fs/ext4/super.c | 5 - fs/ext4/verity.c | 6 +- fs/f2fs/data.c | 3 +- fs/f2fs/verity.c | 6 +- fs/verity/Kconfig | 8 - fs/verity/enable.c | 271 ++++++++++++-------------- fs/verity/fsverity_private.h | 24 +-- fs/verity/hash_algs.c | 24 ++- fs/verity/init.c | 1 - fs/verity/open.c | 163 +++++++++------- fs/verity/signature.c | 2 - fs/verity/verify.c | 346 ++++++++++++++++++++++----------- include/linux/fscrypt.h | 9 +- include/linux/fsverity.h | 93 +++++++-- 22 files changed, 699 insertions(+), 500 deletions(-)
