Hi Herbert, with the latest cryptodev-2.6 tree I find the following: name : cbc(aes) driver : cbc(aes-aesni) module : kernel priority : 300 refcnt : 1 selftest : passed internal : no type : givcipher async : no blocksize : 16 min keysize : 16 max keysize : 32 ivsize : 16 geniv : eseqiv name : cbc(aes) driver : cbc(aes-aesni) module : cbc priority : 300 refcnt : 1 selftest : passed internal : no type : blkcipher blocksize : 16 min keysize : 16 max keysize : 32 ivsize : 16 geniv : <default> Note the type of the ciphers. With this, an allocation of cbc(aes-aesni) does not work (ENOENT). Any ideas? -- Ciao Stephan -- 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
