commit 471fbbea7ff7 ("ext4: handle casefolding with encryption") is missing a few checks for the encryption key which are needed to support deleting enrypted casefolded files when the key is not present. This bug made it impossible to delete encrypted+casefolded directories without the encryption key, due to errors like: W : EXT4-fs warning (device vdc): __ext4fs_dirhash:270: inode #49202: comm Binder:378_4: Siphash requires key Repro steps in kvm-xfstests test appliance: mkfs.ext4 -F -E encoding=utf8 -O encrypt /dev/vdc mount /vdc mkdir /vdc/dir chattr +F /vdc/dir keyid=$(head -c 64 /dev/zero | xfs_io -c add_enckey /vdc | awk '{print $NF}') xfs_io -c "set_encpolicy $keyid" /vdc/dir for i in `seq 1 100`; do mkdir /vdc/dir/$i done xfs_io -c "rm_enckey $keyid" /vdc rm -rf /vdc/dir # fails with the bug Fixes: 471fbbea7ff7 ("ext4: handle casefolding with encryption") Signed-off-by: Daniel Rosenberg <drosen@google.com> Link: https://lore.kernel.org/r/20210522004132.2142563-1-drosen@google.com Signed-off-by: Theodore Ts'o <tytso@mit.edu>
