net: fix uninitialized variable issue

2016-01-23T04:55:49Z

[ Upstream commit 130ed5d105dde141e7fe60d5440aa53e0a84f13b ] msg_iocb needs to be initialized on the recv/recvfrom path. Otherwise afalg will wrongly interpret it as an async call.

net: Add a struct net parameter to sock_create_kern

2015-05-11T14:50:17Z

This is long overdue, and is part of cleaning up how we allocate kernel sockets that don't reference count struct net. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

tun: Utilize the normal socket network namespace refcounting.

2015-05-11T14:50:16Z

There is no need for tun to do the weird network namespace refcounting. The existing network namespace refcounting in tfile has almost exactly the same lifetime. So rewrite the code to use the struct sock network namespace refcounting and remove the unnecessary hand rolled network namespace refcounting and the unncesary tfile->net. This change allows the tun code to directly call sock_put bypassing sock_release and making SOCK_EXTERNALLY_ALLOCATED unnecessary. Remove the now unncessary tun_release so that if anything tries to use the sock_release code path the kernel will oops, and let us know about the bug. The macvtap code already uses it's internal socket this way. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

make new_sync_{read,write}() static

2015-04-12T02:29:40Z

All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases. Signed-off-by: Al Viro

switch kernel_sendmsg() and kernel_recvmsg() to iov_iter_kvec()

2015-04-09T04:02:34Z

For kernel_sendmsg() that eliminates the need to play with setfs(); for kernel_recvmsg() it does *not* - a couple of callers are using it with non-NULL ->msg_control, which would be treated as userland address on recvmsg side of things. In all cases we are really setting a kvec-backed iov_iter, though. Signed-off-by: Al Viro
