The AEAD decrypt interface includes the authentication tag in req->cryptlen. Therefore we need to exlucde that when doing a walk over it. This patch adds separate walker functions for AEAD encryption and decryption. Signed-off-by:

When using SGs, only heap memory (memory that is valid as per virt_addr_valid) is allowed to be referenced. The CTR DRBG used to reference the caller-provided memory directly in an SG. In case the caller provided stack memory pointers, the SG mapping is not considered to be valid. In some cases, this would even cause a paging fault. The change adds a new scratch buffer that is used unconditionally to catch the cases where the caller-provided buffer is not suitable for use in an SG. The crypto operation of the CTR DRBG produces its output with that scratch buffer and finally copies the content of the scratch buffer to the caller's buffer. The scratch buffer is allocated during allocation time of the CTR DRBG as its access is protected with the DRBG mutex. Signed-off-by:

With virtually-mapped stacks (CONFIG_VMAP_STACK=y), using the scatterlist crypto API with stack buffers is not allowed, and with appropriate debugging options will cause the 'BUG_ON(!virt_addr_valid(buf));' in sg_set_buf() to be triggered.

For authenc / stitched AEAD algorithms, check independently each of the two (authentication, encryption) keys whether inlining is possible. Prioritize the inlining of the authentication key, since the length of the (split) key is bigger than that of the encryption key. For the other algorithms, compute only once per tfm the remaining available bytes and decide whether key inlining is possible based on this. Signed-off-by:
