xts_fallback_setkey() in xts_aes_set_key() will now enforce key size rule in FIPS mode when setting up the fallback algorithm keys, which makes the check in xts_aes_set_key() redundant or unreachable. So just drop this check. xts_fallback_setkey() now makes a key size check in xts_verify_key(): xts_fallback_setkey() crypto_skcipher_setkey() [ skcipher_setkey_unaligned() ] cipher->setkey() { .setkey = xts_setkey } xts_setkey() xts_verify_key() Signed-off-by: Vladis Dronov <vdronov@redhat.com> --- arch/s390/crypto/aes_s390.c | 4 ---- 1 file changed, 4 deletions(-)
