* crypto: sha1-mb - Add missing args_digest offsetMegha Dey2016-01-271-1/+1
| | | | | | | | | | | The _args_digest is defined as _args+_digest, both of which are the first members of 2 separate structures, effectively yielding _args_digest to have a value of zero. Thus, no errors have spawned yet due to this. To ensure sanity, adding the missing _args_digest offset to the sha1_mb_mgr_submit.S.

* crypto: atmel-sha - fix context switchesCyrille Pitchen2016-01-252-25/+84
| | | | | | | | | | | | | This patch saves the value of the internal hash register at the end of an 'update' operation then restores this value before starting the next 'update'. This way the driver can now properly handle context switches. WARNING: only hardware versions from sama5d4x and later provide the needed interface to update the internal hash value. Especially, sama5d3x cannot implement this feature so context switches are still broken.

* crypto: atmel-sha - fix a race between the 'done' tasklet and the crypto clientCyrille Pitchen2016-01-251-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'done' tasklet handler used to check the 'BUSY' flag to either finalize the processing of a crypto request which had just completed or manage the crypto queue to start the next crypto request. On request R1 completion, the driver calls atmel_sha_finish_req(), which: 1 - clears the 'BUSY' flag since the hardware is no longer used and is ready again to process new crypto requests. 2 - notifies the above layer (the client) about the completion of the asynchronous crypto request R1 by calling its base.complete() callback. 3 - schedules the 'done' task to check the crypto queue and start to process the next crypto request (the 'BUSY' flag is supposed to be cleared at that moment) if such a pending request exists. However step 2 might wake the client up so it can now ask our driver to process a new crypto request R2. This request is enqueued by calling the atmel_sha_handle_queue() function, which sets the 'BUSY' flags then starts to process R2. If the 'done' tasklet, scheduled by step 3, runs just after, it would see that the 'BUSY' flag is set then understand that R2 has just completed, which is wrong! So the state of 'BUSY' flag is not a proper way to detect and handle crypto request completion. This patch fixes this race condition by using two different tasklets, one to handle the crypto request completion events, the other to manage the crypto queue if needed.

* crypto: atmel-sha - fix crash when computing digest on empty messageCyrille Pitchen2016-01-251-0/+1
| | | | | | | | | | | | | | | | | | | | This patch fixes a crash which occured during the computation of the digest of an empty message. Indeed, when processing an empty message, the atmel_sha_handle_queue() function was never called, hence the dd->req pointer remained uninitialized. Later, when the atmel_sha_final_req() function was called, it used to crash while using this uninitialized dd->req pointer. Hence this patch adds missing initializations of dd->req before calls of the atmel_sha_final_req() function. This bug prevented us from passing the tcrypt test suite on SHA algo.

* crypto: ccp - Add hash state import and export supportTom Lendacky2016-01-252-0/+46
| | | | | | | | | | | | | | | | | Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero") added a check to prevent ahash algorithms from successfully registering if the import and export functions were not implemented. This prevents an oops in the hash_accept function of algif_hash. This commit causes the ccp-crypto module SHA support and AES CMAC support from successfully registering and causing the ccp-crypto module load to fail because the ahash import and export functions are not implemented. Update the CCP Crypto API support to provide import and export support for ahash algorithms.
