Eric Biggers 47a846536e block/keyslot-manager: prevent crash when num_slots=1 ... If there is only one keyslot, then blk_ksm_init() computes slot_hashtable_size=1 and log_slot_ht_size=0. This causes blk_ksm_find_keyslot() to crash later because it uses hash_ptr(key, log_slot_ht_size) to find the hash bucket containing the key, and hash_ptr() doesn't support the bits == 0 case. Fix this by making the hash table always have at least 2 buckets. Tested by running: kvm-xfstests -c ext4 -g encrypt -m inlinecrypt \ -o blk-crypto-fallback.num_keyslots=1 Fixes: 1b26283970 ("block: Keyslot Manager for Inline Encryption") Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>		2020-11-20 11:52:52 -07:00
