crypto: algif_hash - wait for crypto_ahash_init() to complete

2016-01-30T14:05:15Z

hash_sendmsg/sendpage() need to wait for the completion of crypto_ahash_init() otherwise it can cause panic. Cc: stable@vger.kernel.org Signed-off-by: Rui Wang Signed-off-by: Herbert Xu

crypto: algif_hash - Fix race condition in hash_check_key

2016-01-18T10:16:34Z

We need to lock the child socket in hash_check_key as otherwise two simultaneous calls can cause the parent socket to be freed. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: algif_hash - Remove custom release parent function

2016-01-18T10:16:33Z

This patch removes the custom release parent function as the generic af_alg_release_parent now works for nokey sockets too. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: algif_hash - Require setkey before accept(2)

2016-01-18T10:16:11Z

Hash implementations that require a key may crash if you use them without setting a key. This patch adds the necessary checks so that if you do attempt to use them without a key that we return -ENOKEY instead of proceeding. This patch also adds a compatibility path to support old applications that do acept(2) before setkey. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: algif_hash - Only export and import on sockets with data

2015-11-02T09:48:30Z

The hash_accept call fails to work on sockets that have not received any data. For some algorithm implementations it may cause crashes. This patch fixes this by ensuring that we only export and import on sockets that have received data.

net: Remove iocb argument from sendmsg and recvmsg

2015-03-02T18:06:31Z

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: switch af_alg_make_sg() to iov_iter

2015-02-04T06:34:15Z

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. Cc: linux-crypto@vger.kernel.org Signed-off-by: Al Viro

put iov_iter into msghdr

2014-12-09T21:29:03Z

Note that the code _using_ ->msg_iter at that point will be very unhappy with anything other than unshifted iovec-backed iov_iter. We still need to convert users to proper primitives. Signed-off-by: Al Viro
