[PATCH v2 0/5] crypto: add algif_akcipher user space API

[Stephan Mueller <smueller@chronox.de>]

Hi,

This patch set adds the AF_ALG user space API to externalize the
asymmetric cipher API recently added to the kernel crypto API.

The patch set is tested with the user space library of libkcapi [1].
Use [1] test/test.sh for a full test run. The test covers the
following scenarios:

	* sendmsg of one IOVEC

	* sendmsg of 16 IOVECs with non-linear buffer

	* vmsplice of one IOVEC

	* vmsplice of 15 IOVECs with non-linear buffer

	* invoking multiple separate cipher operations with one
	  open cipher handle

	* encryption with private key (using vector from testmgr.h)

	* encryption with public key (using vector from testmgr.h)

	* decryption with private key (using vector from testmgr.h)

The patch set includes a fix for the MPI parsing that is visible when
using SGL members that contain one byte.

Changes v2:
 * use updated SGL-based akcipher API
 * allow mix-n-match of sendmsg and vmsplice calls
