Patch 863b557a added NULL entries for intel accelerated drivers but did not marked these fips allowed. This cause panic if running tests with fips=1. For ghash, fips_allowed flag was added in patch 18c0ebd2. Without patch, "modprobe tcrypt" fails with alg: skcipher: Failed to load transform for cbc-aes-aesni: -2 cbc-aes-aesni: cbc(aes) alg self test failed in fips mode! (panic) Also add missing cryptd(__driver-cbc-aes-aesni) and cryptd(__driver-gcm-aes-aesni) test to complement null tests above, otherwise system complains with alg: No test for __cbc-aes-aesni (cryptd(__driver-cbc-aes-aesni)) alg: No test for __gcm-aes-aesni (cryptd(__driver-gcm-aes-aesni)) Signed-off-by:

This patch supports Exynos SOC's PRNG driver. Exynos's PRNG has 5 seeds and 5 random number outputs. Module is excuted under runtime power management control, so it activates only while it's in use. Otherwise it will be suspended generally. It was tested on PQ board by rngtest program. Signed-off-by:

kfree(new_key_mem) in rfc4106_set_key() should be called on malloced pointer, not on aligned one, otherwise it can cause invalid pointer on free. (Seen at least once when running tcrypt tests with debug kernel.) Signed-off-by:

This patch adds support for retrieving and printing of SEC ERA information. It is useful for knowing beforehand what features exist from the SEC point of view on a certain SoC. Only era-s 1 to 4 are currently supported; other eras will appear as unknown. Signed-off-by:

The caam job rings (input/output job ring) are allocated using dma_map_single(). These job rings can be visualized as the ring buffers in which the jobs are en-queued/de-queued. The s/w enqueues the jobs in input job ring which h/w dequeues and after processing it copies the jobs in output job ring. Software then de-queues the job from output ring. Using dma_map/unmap_single() is not preferred way to allocate memory for this type of requirements because this adds un-necessary complexity. Example, if bounce buffer (SWIOTLB) will get used then to make any change visible in this memory to other processing unit requires dmap_unmap_single() or dma_sync_single_for_cpu/device(). The dma_unmap_single() can not be used as this will free the bounce buffer, this will require changing the job rings on running system and I seriously doubt that it will be not possible or very complex to implement. Also using dma_sync_single_for_cpu/device() will also add unnecessary complexity. The simple and preferred way is using dma_alloc_coherent() for these type of memory requirements. This resolves the Linux boot crash issue when "swiotlb=force" is set in bootargs on systems which have memory more than 4G. Signed-off-by:

git commit 39871037 (crypto: algapi - Move larval completion into algboss) replaced accidentally a call to complete_all() by a call to complete(). This causes a hang on crypto allocation if we have more than one larval waiter. This pach restores the call to complete_all(). Signed-off-by:

there is no noticeable benefit for multiple cores to process one job ring's output ring: in fact, we can benefit from cache effects of having the back-half stay on the core that receives a particular ring's interrupts, and further relax general contention and the locking involved with reading outring_used, since tasklets run atomically.

Memory barriers are implied by the i/o register write implementation (at least on Power). So we can remove the redundant wmb() in caam_jr_enqueue, and, in dequeue(), hoist the h/w done notification write up to before we need to increment the head of the ring, and save an smp_mb. Signed-off-by:

It has been observed that in zero-loss benchmarks, when a slow traffic rate is being tested, the IRQ timer coalescing parameter was set too high, and the ethernet controller would start dropping packets because the job ring back half wouldn't be executed in time before the ethernet controller would fill its buffers, thereby significantly reducing the zero-loss performance figures. Empirical testing has shown that the best zero-loss performance is achieved when IRQ coalescing is set to minimum values and/or turned off, since apparently the job ring driver already implements an adequately-performing general-purpose IRQ mitigation strategy in software. Whilst we could go with minimal count (2-8) and timing settings (192-256), we prefer just turning h/w coalescing altogether off to minimize setkey latency (due to split key generation), and for consistent cross-SoC performance (the SEC vs. core clock ratio changes).

The SEC v4.x' RNGB h/w block self-initialized. RNG4, available on SEC versions 5 and beyond, is based on a different standard that requires manual initialization. Also update any new errors From the SEC v5.2 reference manual: The SEC v5.2's RNG4 unit reuses some error IDs, thus the addition of rng_err_id_list over the CHA-independent err_id_list.

functions for external storage of seq in/out lengths, i.e., for 32-bit lengths.

init_desc, by always ORing with 1 for the descriptor header inclusion into the descriptor length, and init_sh_desc_pdb, by always specifying the descriptor length modification for the PDB via options, would not allow for odd length PDBs to be embedded in the constructed descriptor length. Fix this by simply changing the OR to an addition. also round-up pdb_bytes to the next SEC command unit size, to allow for, e.g., optional packet header bytes that aren't a multiple of CAAM_CMD_SZ.
