## Overview

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

net/rds: Don't sleep inside rds_ib_conn_path_shutdown

New rds rdma self tests exposed a hang when tearing down
the ib network configs.  This is caused by the shutdown worker
thread sleeping on the wait_event call, which blocks other work
items in the queue. Fix this by changing wait_event to
wait_event timeout, and looping until the wait check succeeds.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
