| Subject: rdma_cm: fail iwarp accepts w/o connection params |
| |
| From: Steve Wise <swise@opengridcomputing.com> |
| |
| commit f2625f7db4dd0bbd16a9c7d2950e7621f9aa57ad upstream. |
| |
| cma_accept_iw() needs to return an error if conn_params is NULL. |
| Since this is coming from user space, we can crash. |
