For historical reasons, the AES-NI based implementation of the PCBC chaining mode uses a special FPU chaining mode wrapper template to amortize the FPU start/stop overhead over multiple blocks. When this FPU wrapper was introduced, it supported widely used chaining modes such as XTS and CTR (as well as LRW), but currently, PCBC is the only remaining user. Since there are no known users of pcbc(aes) in the kernel, let's remove this special driver, and rely on the generic pcbc driver to encapsulate the AES-NI core cipher. Signed-off-by:

Add a generic version of output feedback mode. We already have support of several hardware based transformations of this mode and the needed test vectors but we somehow missed adding a generic software one. Fix this now. Signed-off-by:

In preparation for removal of VLAs due to skcipher requests on the stack via SKCIPHER_REQUEST_ON_STACK() usage, this introduces the infrastructure for the "sync skcipher" tfm, which is for handling the on-stack cases of skcipher, which are always non-ASYNC and have a known limited request size. The crypto API additions: struct crypto_sync_skcipher (wrapper for struct crypto_skcipher) crypto_alloc_sync_skcipher() crypto_free_sync_skcipher() crypto_sync_skcipher_setkey() crypto_sync_skcipher_get_flags() crypto_sync_skcipher_set_flags() crypto_sync_skcipher_clear_flags() crypto_sync_skcipher_blocksize() crypto_sync_skcipher_ivsize() crypto_sync_skcipher_reqtfm() skcipher_request_set_sync_tfm() SYNC_SKCIPHER_REQUEST_ON_STACK() (with tfm type check) Signed-off-by:

Add support for aes counter(ctr) block cipher mode of operation for Exynos Hardware. In contrast to ecb and cbc modes, aes-ctr allows encyption/decryption for request sizes not being a multiple of 16(bytes). Hardware requires block sizes being a multiple of 16(bytes). In order to achieve this, copy request source and destination memory, and align it's size to 16. That way hardware processes additional bytes, that are omitted when copying the result back to its original destination. Tested on Odroid-U3 with Exynos 4412 CPU, kernel 4.19-rc2 with crypto run-time self test testmgr. Signed-off-by:

Remove a race condition introduced by error path in functions: s5p_aes_interrupt and s5p_aes_crypt_start. Setting the busy field of struct s5p_aes_dev to false made it possible for s5p_tasklet_cb to change the req field, before s5p_aes_complete was called. Change the first parameter of s5p_aes_complete to struct ablkcipher_request. Before spin_unlock, make a copy of the currently handled request, to ensure s5p_aes_complete function call with the correct request. Signed-off-by:
