net: Fix oops from tcp_collapse() when using splice()
tcp_read_sock() can have a eat skbs without immediately advancing copied_seq. This can cause a panic in tcp_collapse() if it is called as a result of the recv_actor dropping the socket lock. A userspace program that splices data from a socket to either another socket or to a file can trigger this bug. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: David S.
