Description
Description
In the Linux kernel, the following vulnerability has been resolved:
btrfs: retry verity reads for not-uptodate Merkle folios
btrfs_read_merkle_tree_page() can find a folio in the mapping that is not
uptodate. After taking the folio lock, the current code treats that state
as a read error and returns -EIO.
That can make a previous transient read failure sticky. If the failed read
left a not-uptodate folio in the mapping, later callers find that folio and
fail instead of retrying the read.
Keep the existing page-cache insertion and locking order, but retry the
Merkle item read when a not-uptodate folio is found in the mapping. Also
unlock the folio when read_key_bytes() fails so that a later caller can
lock it and retry the read.
