The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.

But the index in RxFIFO has to match with the corresponding entry in FIFO maintained by VAS in kernel. Otherwise NX may be processing incorrect CRBs and can cause CRB timeout. VAS FIFO offset is 0 when the receive window is opened during initialization. When the module is reloaded or in kexec boot, readOffset in FIFO control register may not match with VAS entry.

crypto/nx: Do not initialize workmem allocation 2017-11-11T22:03:11+00:00 Haren Myneni haren@linux.vnet.ibm.com 2017-09-25T06:44:13+00:00 0f46a79a5a048200d4615b2509f01eed97c99b95 We are using percpu send window on P9 NX (powerNV) instead of opening / closing per each crypto session. Means txwin is removed from workmem. So we do not need to initialize workmem for each request. Signed-off-by: Haren Myneni <haren@us.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
