Not sure if this should succeed at all, at least that's not my code. ;) > # ./hmac_comp > requested cipher CRYPTO_AES_CBC and mac CRYPTO_SHA1_HMAC, got cipher > cbc(aes) with driver mv-cbc-aes and hash hmac(sha1) with driver > mv-hmac-sha1 > fail for datalen 0x10, MACs do not match! > wrong mac: > \xd7\xd1\xa6\xef\x0a\x38\xe1\x09\x45\xe1\x8b\x48\x88\xaa\xa9\x23\x4c\xd4\x67\xd1 > right mac: > \xd7\xd1\xa6\xef\x0a\x38\xe1\x09\x45\xe1\x8b\x48\x88\xaa\xa9\x23\x4c\xd4\x67\xd1 > test_crypto() failed for datalen of 16 That's bad. I'm pretty sure SSH uses HMAC. Unless there is a bug in hmac_comp, the fact that identical binary strings are shown for actual and expected result makes me suspect a caching issue (the additional data access while printing sometimes leads to a cache flush so one does not see the complained difference). You are using MV_CESA, therefore you are probably on a Kirkwood with VIVT cache architecture - which is pretty delicate when it comes to the zero-copy stuff involved. Please make sure your kernel doesn't miss any fixes in mv_cesa regarding cache flushes. Also, for the sake of testing you could turn off zero-copy in cryptodev as well.
