linux-stable.git/crypto/algif_skcipher.c, branch v4.4

Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

2015-12-28T18:44:41+00:00

Pull crypto fix from Herbert Xu:
 "This fixes a bug in the algif_skcipher interface that can trigger a
  kernel WARN_ON from user-space.  It does so by using the new skcipher
  interface which unlike the previous ablkcipher does not need to create
  extra geniv objects which is what was used to trigger the WARN_ON"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: algif_skcipher - Use new skcipher interface

crypto: algif_skcipher - Use new skcipher interface

2015-12-22T12:40:01+00:00

This patch replaces uses of ablkcipher with the new skcipher
interface.

net: rename SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA

2015-12-01T20:45:05+00:00

This patch is a cleanup to make following patch easier to
review.

Goal is to move SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA
from (struct socket)->flags to a (struct socket_wq)->flags
to benefit from RCU protection in sock_wake_async()

To ease backports, we rename both constants.

Two new helpers, sk_set_bit(int nr, struct sock *sk)
and sk_clear_bit(int net, struct sock *sk) are added so that
following patch can change their implementation.

trivial conflict in net/socket.c and non-trivial one in crypto -

crypto: algif - explicitly mark end of data

2015-04-02T02:59:28+00:00

After the TX sgl is expanded we need to explicitly mark end of data
at the last buffer that contains data.

Changes in v2
 - use type 'bool' and true/false for 'mark'.

crypto: algif - use kmalloc instead of kzalloc

2015-04-01T19:32:35+00:00

No need to use kzalloc to allocate sgls as the structure is initialized anyway.

crypto: algif - change algif_skcipher to be asynchronous

2015-03-23T20:41:37+00:00

The way the algif_skcipher works currently is that on sendmsg/sendpage it
builds an sgl for the input data and then on read/recvmsg it sends the job
for encryption putting the user to sleep till the data is processed.
This way it can only handle one job at a given time.
This patch changes it to be asynchronous by adding AIO support.
