From: Greg Kroah-Hartman
Date: Tue Oct 03 2017 - 08:30:00 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Steve Wise <swise@xxxxxxxxxxxxxxxxxxxxx>

commit 3d318605f5e32ff44fb290d9b67573b34213c4c8 upstream.

The listening endpoint should always be dereferenced at the end of
pass_accept_req().

Fixes: f86fac79afec ("RDMA/iw_cxgb4: atomic find and reference for listening endpoints")
