Hi, I see that the event CMD_CANCEL_REMAIN_ON_CHANNEL is emitted when a CMD_REMAIN_ON_CHANNEL duration expires, but this is not true for CMD_FRAME when sending offchannel and providing a duration. I see wpa_supplicant handles this with its own timeout, but couldn't the same event be emitted for CMD_FRAME if the duration expires? Looking in mac80211/offchannel.c: ieee80211_roc_notify_destroy: if (!roc->mgmt_tx_cookie) cfg80211_remain_on_channel_expired(&roc->sdata->wdev, roc->cookie, roc->chan, GFP_KERNEL); In the case of CMD_FRAME, mgmt_tx_cookie is set, so this event does not get emitted. Could the same expire event be emitted when mgmt_tx_cookie is set as well? This would eliminate the need for userspace to keep a timeout tracking this. If this is ok I can send a patch (Looks like all I would need to do is remove the if, and include the correct cookie, roc->cookie or roc- >mgmt_tx_cookie). Thanks, James
