Currently the crypto requests were sent to engines sequentially. This commit moves the SRAM I/O operations from the prepare to the step functions. It provides flexibility for future works and allow to prepare a request while the engine is running. Signed-off-by:

So far, the 'process' operation was used to check if the current request was correctly handled by the engine, if it was the case it copied information from the SRAM to the main memory. Now, we split this operation. We keep the 'process' operation, which still checks if the request was correctly handled by the engine or not, then we add a new operation for completion. The 'complete' method copies the content of the SRAM to memory. This will soon become useful if we want to call the process and the complete operations from different locations depending on the type of the request (different cleanup logic). Signed-off-by:

Currently, the only way to access the tdma chain is to use the 'req' union from a mv_cesa_{ablkcipher,ahash}. This will soon become a problem if we want to handle the TDMA chaining vs standard/non-DMA processing in a generic way (with generic functions at the cesa.c level detecting whether the request should be queued at the DMA level or not). Hence the decision to move the chain field a the mv_cesa_req level at the expense of adding 2 void * fields to all request contexts (including non-DMA ones) and to remove the type completly. To limit the overhead, we get rid of the type field, which can now be deduced from the req->chain.first value. Once these changes are done the union is no longer needed, so remove it and move mv_cesa_ablkcipher_std_req and mv_cesa_req to mv_cesa_ablkcipher_req directly. There are also no needs to keep the 'base' field into the union of mv_cesa_ahash_req, so move it into the upper structure. Signed-off-by: -

Add a TDMA descriptor at the end of the request for copying the output IV vector via a DMA transfer. This is a good way for offloading as much as processing as possible to the DMA and the crypto engine. This is also required for processing multiple cipher requests in chained mode, otherwise the content of the IV vector would be overwritten by the last processed request. Signed-off-by:

So far, the way that the type of a TDMA operation was checked was wrong. We have to use the type mask in order to get the right part of the flag containing the type of the operation. Signed-off-by:

Add a BUG_ON() call when the driver tries to launch a crypto request while the engine is still processing the previous one. This replaces a silent system hang by a verbose kernel panic with the associated backtrace to let the user know that something went wrong in the CESA driver. Signed-off-by:

As it is if you ask for a sync gcm you may actually end up with an async one because it does not filter out async implementations of ghash. This patch fixes this by adding the necessary filter when looking for ghash. Cc: stable@vger.kernel.org Signed-off-by: -

The CTR DRBG derives its random data from the CTR that is encrypted with AES. This patch now changes the CTR DRBG implementation such that the CTR AES mode is employed. This allows the use of steamlined CTR AES implementation such as ctr-aes-aesni. Unfortunately there are the following subtile changes we need to apply when using the CTR AES mode: - the CTR mode increments the counter after the cipher operation, but the CTR DRBG requires the increment before the cipher op. Hence, the crypto_inc is applied to the counter (drbg->V) once it is recalculated. - the CTR mode wants to encrypt data, but the CTR DRBG is interested in the encrypted counter only. The full CTR mode is the XOR of the encrypted counter with the plaintext data. To access the encrypted counter, the patch uses a NULL data vector as plaintext to be "encrypted". Signed-off-by:

alloc_workqueue replaces deprecated create_workqueue(). The workqueue device_reset_wq has workitem &reset_data->reset_work per adf_reset_dev_data. The workqueue pf2vf_resp_wq is a workqueue for PF2VF responses has workitem &pf2vf_resp->pf2vf_resp_work per pf2vf_resp. The workqueue adf_vf_stop_wq is used to call adf_dev_stop() asynchronously. Dedicated workqueues have been used in all cases since the workitems on the workqueues are involved in operation of crypto which can be used in the IO path which is depended upon during memory reclaim. Hence, WQ_MEM_RECLAIM has been set to gurantee forward progress under memory pressure. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary. Signed-off-by:

SEC1 doesn't have IPSEC_ESP descriptor type but it is able to perform IPSEC using HMAC_SNOOP_NO_AFEU, which is also existing on SEC2 In order to be able to define descriptors templates for SEC1 without breaking SEC2+, we have to give lower priority to HMAC_SNOOP_NO_AFEU so that SEC2+ selects IPSEC_ESP and not HMAC_SNOOP_NO_AFEU which is less performant. This is done by adding a priority field in the template. If the field is 0, we use the default priority, otherwise we used the one in the field. Signed-off-by:

This patchs enhances the IPSEC_ESP related functions for them to also supports the same operations with descriptor type HMAC_SNOOP_NO_AFEU. The differences between the two descriptor types are: * pointeurs 2 and 3 are swaped (Confidentiality key and Primary EU Context IN) * HMAC_SNOOP_NO_AFEU has CICV out in pointer 6 * HMAC_SNOOP_NO_AFEU has no primary EU context out so we get it from the end of data out Signed-off-by: -

In preparation of IPSEC for SEC1, first step is to make the mapping helpers more generic so that they can also be used by AEAD functions. First, the functions are moved before IPSEC functions in talitos.c talitos_sg_unmap() and unmap_sg_talitos_ptr() are merged as they are quite similar, the second one handling the SEC1 case an calling the first one for SEC2 map_sg_in_talitos_ptr() and map_sg_out_talitos_ptr() are merged into talitos_sg_map() and enhenced to support offseted zones as used for AEAD. The actual mapping is now performed outside that helper. The DMA sync is also done outside to not make it several times. talitos_edesc_alloc() size calculation are fixed to also take into account AEAD specific parts also for SEC1 Signed-off-by:

Bring some consistency by: 1. Replacing fixed-space indentation of structure members with just tabs. 2. Remove indentation in declaration of local variable between type and name. Driver was mixing usage of such indentation and lack of it. When removing indentation, reorder variables in reversed-christmas-tree order with first variables being initialized ones. Signed-off-by:
