Eric Biggers d1c97077fa ext4: add missing validation of fast-commit record lengths ... commit 64b4a25c3d upstream. 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.
