* crypto: caam - desc.h fixesHoria Geantă2016-11-131-8/+8
| | | | | | | | | | | | | | | | | | 1. fix HDR_START_IDX_MASK, HDR_SD_SHARE_MASK, HDR_JD_SHARE_MASK Define HDR_START_IDX_MASK consistently with the other masks: mask = bitmask << offset 2. OP_ALG_TYPE_CLASS1 and OP_ALG_TYPE_CLASS2 must be shifted. 3. fix FIFO_STORE output data type value for AFHA S-Box 4. fix OPERATION pkha modular arithmetic source mask 5. rename LDST_SRCDST_WORD_CLASS1_ICV_SZ to LDST_SRCDST_WORD_CLASS1_IV_SZ (it refers to IV, not ICV).

| | | | | | | | | | | | Commit 4464a7d4f53d756101291da26563f37f7fce40f3 ("crypto: caam - remove error propagation handling") removed error propagation handling only from caamalg.

* crypto: caam - fix AEAD givenc descriptorsAlex Porosanu2016-11-131-1/+3
| | | | | | | | | | | | | | | | | | | | | The AEAD givenc descriptor relies on moving the IV through the output FIFO and then back to the CTX2 for authentication. The SEQ FIFO STORE could be scheduled before the data can be read from OFIFO, especially since the SEQ FIFO LOAD needs to wait for the SEQ FIFO LOAD SKIP to finish first. The SKIP takes more time when the input is SG than when it's a contiguous buffer. If the SEQ FIFO LOAD is not scheduled before the STORE, the DECO will hang waiting for data to be available in the OFIFO so it can be transferred to C2. In order to overcome this, first force transfer of IV to C2 by starting the "cryptlen" transfer first and then starting to store data from OFIFO to the output buffer.

* crypto: engine - Handle the kthread worker using the new APIPetr Mladek2016-10-252-19/+13
| | | | | | | | | | | | | | | | | | | | | | | Use the new API to create and destroy the crypto engine kthread worker. The API hides some implementation details. In particular, kthread_create_worker() allocates and initializes struct kthread_worker. It runs the kthread the right way and stores task_struct into the worker structure. kthread_destroy_worker() flushes all pending works, stops the kthread and frees the structure. This patch does not change the existing behavior except for dynamically allocating struct kthread_worker and storing only the pointer of this structure. It is compile tested only because I did not find an easy way how to run the code. Well, it should be pretty safe given the nature of the change.
