| * crypto: inside-secure - do not rely on the hardware last bit for result ↵Antoine Tenart2019-06-061-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | descriptors When performing a transformation the hardware is given result descriptors to save the result data. Those result descriptors are batched using a 'first' and a 'last' bit. There are cases were more descriptors than needed are given to the engine, leading to the engine only using some of them, and not setting the last bit on the last descriptor we gave. This causes issues were the driver and the hardware aren't in sync anymore about the number of result descriptors given (as the driver do not give a pool of descriptor to use for any transformation, but a pool of descriptors to use *per* transformation). This patch fixes it by attaching the number of given result descriptors to the requests, and by using this number instead of the 'last' bit found on the descriptors to process them.

| * crypto: inside-secure - fix use of the SG listAntoine Tenart2019-06-062-30/+12Star
| | | | | | | | | | | | | | | | | | | | | | Replace sg_nents_for_len by sg_nents when DMA mapping/unmapping buffers and when looping over the SG entries. This fix cases where the SG entries aren't used fully, which would in such cases led to using fewer SG entries than needed (and thus the engine wouldn't have access to the full input data and the result would be wrong).

| | | | | | | | | | | | | | | | | | | | This patch changes the error reported by the Inside Secure SafeXcel driver when a result descriptor reports an error, from -EIO to -EINVAL, as this is what the crypto framework expects.

* crypto: clarify name of WEAK_KEY request flagEric Biggers2019-01-251-1/+1
| | | | | | | | | | | | | | | | | CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: inside-secure - remove request list to improve performanceOfer Heifetz2018-07-085-121/+119Star
| | | | | | | | | | | | | | | | | | | This patch main goal is to improve driver performance by moving the crypto request from a list to a RDR ring shadow. This is possible since there is one producer and one consume for this RDR request shadow and one ring descriptor is left unused. Doing this change eliminates the use of spinlock when accessing the descriptor ring and the need to dynamicaly allocate memory per crypto request. The crypto request is placed in the first RDR shadow descriptor only if there are enough descriptors, when the result handler is invoked, it fetches the first result descriptor from RDR shadow.

* crypto: inside-secure - increase minimum transfer sizeOfer Heifetz2018-06-221-4/+4
| | | | | | | | | | The token size was increased for AEAD support. Occasional authentication fails arise since the result descriptor overflows. This is because the token size and the engine minimal thresholds must be in sync.

This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;
