handle_outgoing_dr_smp() can queue a struct ib_mad_local_private *local on the mad_agent_priv->local_work work queue with local->mad_priv == NULL if device->process_mad() returns IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_REPLY and (!ib_response_mad(&mad_priv->mad.mad) || !mad_agent_priv->agent.recv_handler). In this case, local_completions() will be called with local->mad_priv == NULL. The code does check for this case and skips calling recv_mad_agent->agent.recv_handler() but recv == 0 so kmem_cache_free() is called with a NULL pointer. Also, since recv isn't reinitialized each time through the loop, it can cause a memory leak if recv should have been zero. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> |
