crypto: ccp - ccp_dmaengine_unregister release dma channels

2022-04-08T12:05:41+00:00

[ Upstream commit 54cce8ecb9254f971b40a72911c6da403720a2d2 ] ccp_dmaengine_register adds dma_chan->device_node to dma_dev->channels list but ccp_dmaengine_unregister didn't remove them. That can cause crashes in various dmaengine methods that tries to use dma_dev->channels Fixes: 58ea8abf4904 ("crypto: ccp - Register the CCP as a DMA...")

crypto: ccp - Ensure psp_ret is always init'd in __sev_platform_init_locked()

[ Upstream commit 1e1ec11d3ec3134e05d4710f4dee5f9bd05e828d ] Initialize psp_ret inside of __sev_platform_init_locked() because there are many failure paths with PSP initialization that do not set __sev_do_cmd_locked().

crypto: ccp - Move SEV_INIT retry for corrupted data

2022-01-27T11:02:25+00:00

[ Upstream commit e423b9d75e779d921e6adf5ac3d0b59400d6ba7e ] Move the data corrupted retry of SEV_INIT into the __sev_platform_init_locked() function. This is for upcoming INIT_EX support as well as helping direct callers of __sev_platform_init_locked() which currently do not support the retry.

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.

crypto: ccp - shutdown SEV firmware on kexec

2021-08-06T11:45:25+00:00

The commit 97f9ac3db6612 ("crypto: ccp - Add support for SEV-ES to the PSP driver") added support to allocate Trusted Memory Region (TMR) used during the SEV-ES firmware initialization. The TMR gets locked during the firmware initialization and unlocked during the shutdown. While the TMR is locked, access to it is disallowed. Currently, the CCP driver does not shutdown the firmware during the kexec reboot, leaving the TMR memory locked. Register a callback to shutdown the SEV firmware on the kexec boot.
