[X25]: Fix for broken x25 module.
When a user-space server application calls bind on a socket, then in kernel space this bound socket is considered 'x25-linked' and the SOCK_ZAPPED flag is unset.(As in x25_bind()/af_x25.c). Now when a user-space client application attempts to connect to the server on the listening socket, if the kernel accepts this in-coming call, then it returns a new socket to userland and attempts to reply to the caller. The reply/x25_sendmsg() will fail, because the new socket created on call-accept has its SOCK_ZAPPED flag set by x25_make_new(). (sock_init_data() called by x25_alloc_socket() called by x25_make_new() sets the flag to SOCK_ZAPPED)). Fix: Using the sock_copy_flag() routine available in sock.h fixes this. Tested on 32 and 64 bit kernels with x25 over tcp. Signed-off-by: Shaun Pereira <pereira.shaun@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.
