What it is

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

RDMA/core: Wait for RCU callbacks before unloading ib_core

put_gid_ndev() is queued with call_rcu() and implemented in ib_core.

Stopping the workqueues does not drain callbacks already queued, so RCU

could invoke it after the module code has been unloaded.

synchronize_rcu() does not wait for callbacks. Wait for them after all

producers have stopped.
