The BKL removal in appletalk introduced a use-after-free problem, where atalk_destroy_socket frees a sock, but we still release the socket lock on it. An easy fix is to take an extra reference on the sock and sock_put it when returning from atalk_release. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
