In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix drain SQ hang with no completion

SW generated completions for outstanding WRs posted on SQ after QP is in error target the wrong CQ. This causes the ib_drain_sq to hang with no completion.

Fix this to generate completions on the right CQ.
