First four patches are a resend of the v3 algif_akcipher from
Stephan Mueller, with minor changes after rebase on top of 4.6-rc1.
The next three patches add support for keys stored in system
keyring subsystem.
First patch adds a public_key info struct that is used to query
information about the public key.
For now it only contains information about where the key is stored.
This is to prevent other modules, like AF_ALG using a key that
can not be directly accessed by software. Later, when keyctl
will allow to reference hardware based public keys this can be
extended to describe other characteristic of the key, like
information on what operations a public key supports, size of data
is supported, whether a password is required to unlock it, etc.
Second patch adds support for ALG_SET_KEY_ID and ALG_SET_PUBKEY_ID
commands to AF_ALG, which can be used to reference sw key stored
in the system keyrings.
Third patch adds algif_akcipher nokey hadlers.
Patches generated on top of 4.6-rc1
v3 changes:
- include Stephan's patches (rebased on 4.6-rc1)
- add algif_akcipher nokey hadlers
- add public_key info struct to public_key and helper query functions
- add a check if a key is a software accessible key on af_alg, and
return -ENOKEY if it isn't
v2 changes:
- pass the original skcipher request in ablkcipher.base.data instead of
casting it back from the ablkcipher request.
- rename _req to base_req
- dropped 3/3
