Merge branch 'iocb' into for-davem

2015-04-09T04:01:38+00:00

trivial conflict in net/socket.c and non-trivial one in crypto -
that one had evaded aio_complete() removal.

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 - fix warn: unsigned 'used' is never less than zero

2015-03-25T15:44:18+00:00

Change type from unsigned long to int to fix an issue reported by kbuild robot:
crypto/algif_skcipher.c:596 skcipher_recvmsg_async() warn: unsigned 'used' is
never less than zero.

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.

net: Remove iocb argument from sendmsg and recvmsg

2015-03-02T18:06:31+00:00

After TIPC doesn't depend on iocb argument in its internal
implementations of sendmsg() and recvmsg() hooks defined in proto
structure, no any user is using iocb argument in them at all now.
Then we can drop the redundant iocb argument completely from kinds of
implementations of both sendmsg() and recvmsg() in the entire
networking stack.

crypto: fix af_alg_make_sg() conversion to iov_iter

2015-02-11T03:55:45+00:00

Commit 1d10eb2f156f ("crypto: switch af_alg_make_sg() to iov_iter")
broke af_alg_make_sg() and skcipher_recvmsg() in the process of moving
them to the iov_iter interfaces.  The 'npages' calculation in the formar
calculated the number of *bytes* in the pages, and in the latter case
the conversion didn't re-read the value of 'ctx->used' after waiting for
it to become non-zero.

This reverts to the original code for both these cases.

crypto: switch af_alg_make_sg() to iov_iter

2015-02-04T06:34:15+00:00

With that, all ->sendmsg() instances are converted to iov_iter primitives
and are agnostic wrt the kind of iov_iter they are working with.
So's the last remaining ->recvmsg() instance that wasn't kind-agnostic yet.
All ->sendmsg() and ->recvmsg() advance ->msg_iter by the amount actually
copied and none of them modifies the underlying iovec, etc.
