4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------ From: Mark Bloch <[email protected]> commit 5ed935e861a4cbf2158ad3386d6d26edd60d2658 upstream. In case ibnl_put_msg fails in send_nlmsg_done, the function returns with -ENOMEM without freeing. This patch fixes this behavior.
