* crypto: inside-secure - do not use memset on MMIOAntoine Tenart2018-05-261-2/+2
| | | | | | | | | | | | This patch fixes the Inside Secure driver which uses a memtset() call to set an MMIO area from the cryptographic engine to 0. This is wrong as memset() isn't guaranteed to work on MMIO for many reasons. This led to kernel paging request panics in certain cases. Use memset_io() instead.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * crypto: inside-secure - improve the skcipher tokenAntoine Tenart2018-03-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
