Subject: dm crypt: fix crypt_ctr_cipher_new return value on invalid AEAD cipher
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2a32897c840be1c0a0525f4279b365781acfba24;p=linux.git

dm crypt: fix crypt_ctr_cipher_new return value on invalid AEAD cipher

If the user specifies invalid AEAD cipher, dm-crypt should return the
error returned from crypt_ctr_auth_spec, not -ENOMEM.
