Make use of the swap macro and remove unnecessary variable *tmp*. This makes the code easier to read and maintain. This code was detected with the help of Coccinelle. Signed-off-by:

Commit b73b7ac0 ("crypto: sha256_generic - add cra_priority") gave sha256-generic and sha224-generic a cra_priority of 100, to match the convention for generic implementations. But sha256-arm64 and sha224-arm64 also have priority 100, so their order relative to the generic implementations became ambiguous. Therefore, increase their priority to 125 so that they have higher priority than the generic implementations but lower priority than the NEON implementations which have priority 150. Signed-off-by:

Header was defining CRCPOLY_LE/BE and CRC32C_POLY_LE but in fact all of them are CRC-32 polynomials so use consistent naming. Signed-off-by:

Krzysztof Kozlowski authored
Allow other drivers and parts of kernel to use the same define for CRC32 polynomial, instead of duplicating it in many places. This code does not bring any functional changes, except moving existing code. Signed-off-by:

Add support for probing on ACPI systems, with ACPI HID QCOM8160. On ACPI systems, clocks are always enabled, the PRNG should already be enabled, and the register region is read-only. The driver only verifies that the hardware is already enabled never tries to disable or configure it. Signed-off-by:

This patch fixes two typos related to unregistering algorithms supported by SAHARAH 3. In sahara_register_algs the wrong algorithms are unregistered in case of an error. In sahara_unregister_algs the wrong array is used to determine the iteration count. Signed-off-by:

In the cipher safexcel_send_req function, GCC warns that first_rdesc may be used uninitialized. While this should never happen, this patch removes the warning by initializing this variable to NULL to make GCC happy. This was reported by the kbuild test robot. Signed-off-by:

The CTR DRBG requires two SGLs pointing to input/output buffers for the CTR AES operation. The used SGLs always have only one entry. Thus, the SGL can be initialized during allocation time, preventing a re-initialization of the SGLs during each call. The performance is increased by about 1 to 3 percent depending on the size of the requested buffer size. Signed-off-by:

Cast *val* to u64 in order to give the compiler complete information about the proper arithmetic to use.

The wait_event() function is used to detect command completion. The interrupt handler will set the wait condition variable when the interrupt is triggered. However, the variable used for wait_event() is initialized after the command has been submitted, which can create a race condition with the interrupt handler and result in the wait_event() never returning. Move the initialization of the wait condition variable to just before command submission.

The ccree driver implemented NIST 800-38A CBC-CS2 ciphertext format, which only reverses the last two blocks if the stolen ciphertext amount are none zero. Move it to the kernel chosen format of CBC-CS3 which swaps the final blocks unconditionally and rename it to "cts" now that it complies with the kernel format and passes the self tests. Ironically, the CryptoCell REE HW does just that, so the fix is dropping the code that forced it to use plain CBC if the ciphertext was block aligned. Signed-off-by:

We were copying our last cipher block into the request for use as IV for all modes of operations. Fix this by discerning the behaviour based on the mode of operation used: copy ciphertext for CBC, update counter for CTR.

Some crypto API users allocating a tfm with crypto_alloc_$FOO() are also specifying the type flags for $FOO, e.g. crypto_alloc_shash() with CRYPTO_ALG_TYPE_SHASH. But, that's redundant since the crypto API will override any specified type flag/mask with the correct ones. So, remove the unneeded flags. This patch shouldn't change any actual behavior.

Some skcipher algorithms set .cra_flags = CRYPTO_ALG_TYPE_SKCIPHER. But this is redundant with the C structure type ('struct skcipher_alg'), and crypto_register_skcipher() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the skcipher algorithms. This patch shouldn't change any actual behavior.
