4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Mark Bloch <markb@xxxxxxxxxxxx>
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.
Fixes: 30dc5e63d6a5 ("RDMA/core: Add support for iWARP Port Mapper user space service")
