In netdevice.h we removed the structure in net-next that is being changes in 'net'. In macsec.c and rtnetlink.c we have overlaps between fixes in 'net' and the u64 attribute changes in 'net-next'. The mlx5 conflicts have to do with vxlan support dependencies. Signed-off-by: David S. Miller

net: fix infoleak in llc

2016-05-04T20:18:48Z

The stack object “info” has a total size of 12 bytes. Its last byte is padding which is not initialized and leaked via “put_cmsg”. Signed-off-by: Kangjie Lu Signed-off-by: David S. Miller

sock: tigthen lockdep checks for sock_owned_by_user

2016-04-14T02:37:20Z

sock_owned_by_user should not be used without socket lock held. It seems to be a common practice to check .owned before lock reclassification, so provide a little help to abstract this check away.

af_llc: fix types on llc_ui_wait_for_conn

2016-02-17T21:12:13Z

The timeout is a long, we return it truncated if it is huge. Basically harmless as the only caller does a boolean check, but tidy it up anyway. (64bit build tested this time. Thank you 0day) Signed-off-by: Alan Cox Signed-off-by: David S. Miller

tcp: fix recv with flags MSG_WAITALL | MSG_PEEK

2015-07-27T08:06:53Z

Currently, tcp_recvmsg enters a busy loop in sk_wait_data if called with flags = MSG_WAITALL | MSG_PEEK. sk_wait_data waits for sk_receive_queue not empty, but in this case, the receive queue is not empty, but does not contain any skb that we can use. Add a "last skb seen on receive queue" argument to sk_wait_data, so that it sleeps until the receive queue has new skbs.

net: Pass kern from net_proto_family.create to sk_alloc

2015-05-11T14:50:17Z

In preparation for changing how struct net is refcounted on kernel sockets pass the knowledge that we are creating a kernel socket from sock_create_kern through to sk_alloc. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

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.

net: llc: use correct size for sysctl timeout entries

2015-01-25T08:23:21Z

The timeout entries are sizeof(int) rather than sizeof(long), which means that when they were getting read we'd also leak kernel memory to userspace along with the timeout values. Signed-off-by: Sasha Levin Signed-off-by: David S. Miller
