mac80211: disable beacon monitor while going offchannel

2010-09-16T19:46:17Z

The beacon monitor should be disabled when going off channel to prevent spurious warnings and triggering connection deterioration work such as sending probe requests. Re-enable the beacon monitor once we come back to the home channel. This patch has fixes for stable kernels [2.6.34+]. Cc: stable@kernel.org Cc: Paul Stewart Cc: Amod Bodas Signed-off-by: Luis R.

mac80211: reset connection idle when going offchannel

2010-09-16T19:46:15Z

When we go offchannel mac80211 currently leaves alive the connection idle monitor. This should be instead postponed until we come back to our home channel, otherwise by the time we get back to the home channel we could be triggering unecesary probe requests. For APs that do not respond to unicast probe requests (Nexus One is a simple example) this means we essentially get disconnected after the probes fails. This patch has stable fixes for kernels [2.6.35+] Cc: stable@kernel.org Cc: Paul Stewart Cc: Amod Bodas Signed-off-by: Luis R. Rodriguez Signed-off-by: John W. Linville

mac80211: fix offchannel queue stop

2010-08-27T17:53:31Z

Somebody noticed this problem, and I outlined to them how to fix it, but haven't heard back from them. So while I was adding the state field I figured I could use it to fix it. The problem, as I understand it, is that when we go offchannel while the driver has a queue stopped, the driver will likely start draining the queue and then enable it while offchannel. This in turn will enable the interface queue, and that leads to transmitting data frames on the wrong channel. Fix this by keeping track of offchannel status per interface, and not enabling the interface queues on interfaces that are offchannel when the driver enables a queue.

mac80211: Fixed netif_tx_wake_all_queues in IBSS mode

2010-01-15T21:58:28Z

When ieee80211_offchannel_return is called, it needs to re-enabled TX queues that have been stopped in ieee80211_offchannel_stop_beaconing or ieee80211_offchannel_stop_station. It happens if we are doing a scan with an IBSS interface. In this case, the interface stopped transmitting. Signed-off-by: Benoit Papillault Signed-off-by: John W. Linville

mac80211: support remain-on-channel command

2009-12-28T21:55:03Z

This implements the new remain-on-channel cfg80211 command in mac80211, extending the work interface. Also change the work purge code to be able to clean up events properly (pretending they timed out.) Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: Generalize off-channel operation helpers from scan code

2009-12-28T21:55:01Z

The off-channel operations for going into power save mode (station mode) or stop beaconing (AP/IBSS) are not limited to scanning. Move these into a separate file and allow them to be used for other purposes, too. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg Signed-off-by: John W. Linville
