When we have an unaligned SG list entry where there is no leftover aligned data, the hash walk code will incorrectly return zero as if the entire SG list has been processed. This patch fixes it by moving onto the next page instead. Reported-by:

In the AES cases enum spu_cipher_type and enum hash_type have the same values, so the assignment is fine. Explicitly cast the enum type conversion. This fixes two warnings when building with clang: drivers/crypto/bcm/cipher.c:821:34: warning: implicit conversion from enumeration type 'enum spu_cipher_type' to different enumeration type 'enum hash_type' [-Wenum-conversion] hash_parms.type = cipher_parms.type; ~ ~~~~~~~~~~~~~^~~~ drivers/crypto/bcm/cipher.c:1412:26: warning: implicit conversion from enumeration type 'enum spu_cipher_type' to different enumeration type 'enum hash_type' [-Wenum-conversion] hash_parms.type = ctx->cipher_type; ~ ~~~~~^~~~~~~~~~~ Signed-off-by:Stefan Agner <stefan@agner.ch> Signed-off-by:

This patch reverts commit 9c521a20 ("crypto: api - remove instance when test failed") and fixes the underlying problem in a different way. To recap, prior to the reverted commit, an instance that fails a self-test is kept around. However, it would satisfy any new lookups against its name and therefore the system may accumlulate an unbounded number of failed instances for the same algorithm name. The reverted commit fixed it by unregistering the instance. Hoever, this still does not prevent the creation of the same failed instance over and over again each time the name is looked up. This patch fixes it by keeping the failed instance around, just as we would if it were a normal algorithm. However, the lookup code has been udpated so that we do not attempt to create another instance as long as this failed one is still registered. Of course, you could still force a new creation by deleting the instance from user-space. A new error (ELIBBAD) has been commandeered for this purpose and will be returned when all registered algorithm of a given name have failed the self-test. Signed-off-by:

This patches uses the state size of the algorithms instead of their digest size to copy the ipad and opad in the context. This doesn't fix anything as the state and digest size are the same for many algorithms, and for all the hmac currently supported by this driver. However hmac(sha224) use the sha224 hash function which has a different digest and state size. This commit prepares the addition of such algorithms. Signed-off-by:

The token used for encryption and decryption of skcipher algorithms sets its stat field to "last packet". As it's a cipher only algorithm, there is not hash operation and thus the "last hash" bit should be set to tell the internal engine no hash operation should be performed. This does not fix a bug, but improves the token definition to follow exactly what's advised by the datasheet. Signed-off-by:

This patches moves the digest information from the transformation context to the request context. This fixes cases where HMAC init functions were called and override the digest value for a short period of time, as the HMAC init functions call the SHA init one which reset the value. This lead to a small percentage of HMAC being incorrectly computed under heavy load. Fixes: 1b44c5a6 ("crypto: inside-secure - add SafeXcel EIP197 crypto engine driver") Suggested-by:

cpt_device_init() is never called in atomic context. The call chain ending up at cpt_device_init() is: [1] cpt_device_init() <- cpt_probe() cpt_probe() is only set as ".probe" in pci_driver structure "cpt_pci_driver". Despite never getting called from atomic context, cpt_device_init() calls mdelay(100), i.e. busy wait for 100ms. That is not necessary and can be replaced with msleep to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself. Signed-off-by:

The decision to rebuild .S_shipped is made based on the relative timestamps of .S_shipped and .pl files but git makes this essentially random. This means that the perl script might run anyway (usually at most once per checkout), defeating the whole purpose of _shipped. Fix by skipping the rule unless explicit make variables are provided: REGENERATE_ARM_CRYPTO or REGENERATE_ARM64_CRYPTO. This can produce nasty occasional build failures downstream, for example for toolchains with broken perl. The solution is minimally intrusive to make it easier to push into stable.

The clock is optional, but if it is present we should managed it. If there is an error while trying getting it, we should exit and report this error. So instead of returning an error only in the -EPROBE case, turn it in an other way and ignore the clock only if it is not present (-ENOENT case). Signed-off-by:

CBC MAC is strictly sequential, and so the current AES code simply processes the input one block at a time. However, we are about to add yield support, which adds a bit of overhead, and which we prefer to align with other modes in terms of granularity (i.e., it is better to have all routines yield every 64 bytes and not have an exception for CBC MAC which yields every 16 bytes) So unroll the loop by 4. We still cannot perform the AES algorithm in parallel, but we can at least merge the loads and stores. Signed-off-by:
