iucv: Fix missing msg_namelen update in iucv_sock_recvmsg()
[ Upstream commit a5598bd9c087dc0efc250a5221e5d0e6f584ee88 ]
The current code does not fill the msg_name member in case it is set.
It also does not set the msg_namelen member to 0 and therefore makes
net/socket.c leak the local, uninitialized sockaddr_storage variable
to userland -- 128 bytes of kernel stack memory.
Fix that by simply setting msg_namelen to 0 as obviously nobody cared
about iucv_sock_recvmsg() not filling the msg_name in case it was set.
