crypto: octeontx2 - set assoclen in aead_do_fallback()

2021-11-18T18:16:33+00:00

[ Upstream commit 06f6e365e2ecf799c249bb464aa9d5f055e88b56 ] Currently, in case of aead fallback, no associated data info is set in the fallback request. To fix this, call aead_request_set_ad() to pass the assoclen.

crypto: qat - disregard spurious PFVF interrupts

[ Upstream commit 18fcba469ba5359c1de7e3fb16f7b9e8cd1b8e02 ] Upon receiving a PFVF message, check if the interrupt bit is set in the message. If it is not, that means that the interrupt was probably triggered by a collision. In this case, disregard the message and re-enable the interrupts.

This is done after the remote function confirms that the message has been received, by clearing the interrupt bit, or the maximum number of attempts (ADF_IOV_MSG_ACK_MAX_RETRY) to check the CSR has been exceeded.

crypto: qat - power up 4xxx device

2021-11-18T18:16:25+00:00

[ Upstream commit ca605f97dae4bf070b7c584aec23c1c922e4d823 ] After reset or boot, QAT 4xxx devices are inactive and require to be explicitly activated. This is done by writing the DRV_ACTIVE bit in the PM_INTERRUPT register and polling the PM_INIT_STATE to make sure that the transaction has completed properly. If this is not done, the driver will fail the initialization sequence reporting the following message: [ 22.081193] 4xxx 0000:f7:00.0: enabling device (0140 -> 0142) [ 22.720285] QAT: AE0 is inactive!!

The device init function has been added to adf_dev_init(), and not in the probe of 4xxx to make sure that the device is re-enabled in case of reset. Note that the error code reported by hw_data->init_device() in adf_dev_init() has been shadowed for consistency with the other calls in the same function.

crypto: caam - disable pkc for non-E SoCs

2021-11-18T18:16:25+00:00

[ Upstream commit f20311cc9c58052e0b215013046cbf390937910c ] On newer CAAM versions, not all accelerators are disabled if the SoC is a non-E variant. While the driver checks most of the modules for availability, there is one - PKHA - which sticks out. On non-E variants it is still reported as available, that is the number of instances is non-zero, but it has limited functionality. In particular it doesn't support encryption and decryption, but just signing and verifying. This is indicated by a bit in the PKHA_MISC field. Take this bit into account if we are checking for availability. This will the following error: [ 8.167817] caam_jr 8020000.jr: 20000b0f: CCB: desc idx 11: : Invalid CHA selected.

crypto: ccp - fix resource leaks in ccp_run_aes_gcm_cmd()

2021-09-24T07:58:41+00:00

There are three bugs in this code: 1) If we ccp_init_data() fails for &src then we need to free aad. Use goto e_aad instead of goto e_ctx. 2) The label to free the &final_wa was named incorrectly as "e_tag" but it should have been "e_final_wa". One error path leaked &final_wa. 3) The &tag was leaked on one error path. In that case, I added a free before the goto because the resource was local to that block.
