Hi Sean,
Looking on that case, I noted that the CM code (SB) checks that the GID
in the incoming
REQ is present in at least of one the ports of the relevant device, but
not specifically on
the port this request arrived to, is that following IBTA? I thought it
could be problematic
e.g in the case of RC QP being set by this establishment, later the RC
packets would be dropped
by the device if they have GRH and the GID isn't on that port table,
isn't that?
Or.
ret = cm_init_av_by_path(&work->path[0], &cm_id_priv->av);
if (ret) {
ib_get_cached_gid(work->port->cm_dev->ib_device,
work->port->port_num, 0,
&work->path[0].sgid);
ib_send_cm_rej(cm_id, IB_CM_REJ_INVALID_GID,
&work->path[0].sgid, sizeof work->path[0].sgid,
NULL, 0);
goto rejected;
}
read_lock_irqsave(&cm.device_lock, flags);
list_for_each_entry(cm_dev, &cm.device_list, list) {
if (!ib_find_cached_gid(cm_dev->ib_device, &path->sgid,
&p, NULL)) {
port = cm_dev->port[p-1];
break;
}
}
read_unlock_irqrestore(&cm.device_lock, flags);
if (!port)
return -EINVAL;
