Please check the aead failures when enabling self-tests (CONFIG_CRYPTO_MANAGER_DISABLE_TESTS not set). They seem related with the lack of cache coherency support in caamalg.c. > - register I/O primitive support > - scatter/gather entry modifications > - clocking support > - i.MX6 device tree support for CAAM > - DMA fixes > > These patches have been tested on the i.MX6 and regression tested > on QorIQ platforms.

Accordingly, all algorithms (hash-only or aead) that use them fail with MDHA Mode error. The driver should not be advertising these algorithms to Crypto API unless supported (MDVID >=1). 3. Another type of failures is the following: caam_jr 2101000.jr0: 40001d0a: DECO: desc idx 29: Invalid FIFO LOAD Command alg: aead: encryption failed on test 1 for rfc4106-gcm-aes-caam: ret=-1073749258 caam_jr 2101000.jr0: 40001c0a: DECO: desc idx 28: Invalid FIFO LOAD Command alg: aead: encryption failed on test 1 for rfc4543-gcm-aes-caam: ret=-1073749002 caam_jr 2101000.jr0: 4000210a: DECO: desc idx 33: Invalid FIFO LOAD Command alg: aead: encryption failed on test 1 for gcm-aes-caam: ret=-1073750282 Thanks, Horia -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
