| H A D | fast_commit.h | diff 64b4a25c3de81a69724e888ec2db3533b43816e2 Sun Nov 06 16:48:38 CST 2022 Eric Biggers <ebiggers@google.com> ext4: add missing validation of fast-commit record lengths
Validate the inode and filename lengths in fast-commit journal records
so that a malicious fast-commit journal cannot cause a crash by having
invalid values for these. Also validate EXT4_FC_TAG_DEL_RANGE.
Fixes: aa75f4d3daae ("ext4: main fast-commit commit path")
