Subject: question on beacon-loss messages
Date: Wed, 13 Mar 2013 15:17:03 -0700	[thread overview]
Message-ID: <5140FADF.9060307@candelatech.com> (raw)

I am wondering, should the rssi_notify() call only be made if 'beacon' is
true?

I'm seeing lots of beacon-miss events, but when I print out the beacon-loss counters,
they are zero (or much smaller than the number of events I see come out of 'iw').



static void ieee80211_mgd_probe_ap(struct ieee80211_sub_if_data *sdata,
				   bool beacon)
{
	struct ieee80211_if_managed *ifmgd = &sdata->u.mgd;
	bool already = false;

	if (!ieee80211_sdata_running(sdata))
		return;

	mutex_lock(&ifmgd->mtx);

	if (!ifmgd->associated)
		goto out;

	mutex_lock(&sdata->local->mtx);

	if (sdata->local->tmp_channel || sdata->local->scanning) {
		mutex_unlock(&sdata->local->mtx);
		goto out;
	}

	if (beacon)
		mlme_dbg_ratelimited(sdata,
				     "detected beacon loss from AP - probing\n");

	ieee80211_cqm_rssi_notify(&sdata->vif,
		NL80211_CQM_RSSI_BEACON_LOSS_EVENT, GFP_KERNEL);


Thanks,
Ben
