| * | | mac80211: make ieee802_11_parse_elems an inlineJohannes Berg2013-04-08

| * | | mac80211: don't start new netdev queues if driver stoppedJohannes Berg2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a new netdev (e.g. an AP VLAN) is created while the driver has queues stopped, the new netdev queues will be started even though they shouldn't. This will lead to frames accumulating on the internal mac80211 pending queues instead of properly being held on the netdev queues. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | mac80211: replace some dead code by a warningJohannes Berg2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the (nested) switch statements, this code can't be reached, so make it warn instead of manipulating the carrier state which seems purposeful. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | mac80211: don't fiddle with netdev queues in MLME codeJohannes Berg2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The netdev queues should always represent the state that the driver gave them, so fiddling with them isn't really appropriate in the mlme code. Also, since we stop queues for flushing now, this really isn't necessary any more. As the scan/offchannel code has also been modified to no longer do this a while ago, remove the outdated smp_mb() and comments about it. While at it, also add a pair of braces that was missing.

| * | | mac80211: disable uAPSD if all ACs are under ACMAlexander Bondar2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's unlikely that an AP requires WMM mandatory admission control for all access categories, and if it does then we still transmit on the background AC without requesting admission. However, avoid using uAPSD in this case since the implementation could run into issues and might use other ACs etc. Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | mac80211: fix do_stop handling while suspendedJohannes Berg2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a device is unplugged while suspended, mac80211 is de-initialized and all interfaces are removed while no state is actually present in the driver. This can cause warnings and driver confusion. Fix this by reordering the do_stop code to not call the driver when it is suspended, i.e. when there's no state in the driver anyway. The previous patches removed a few corner cases in ROC and virtual monitor interfaces so that now this is safe to do and no state should be left over.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has to be removed from the driver, but completely destroying it helps handle unplug of a device during suspend since then the channel context handling etc. doesn't have to happen later when it's removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | They can't really be executed while suspended and could trigger work warnings, so abort all ROC items. When the system resumes the notifications about this will be delivered to userspace which can then act accordingly (though it will assume they were canceled/finished.)

| * | | mac80211: return new mpath from mesh_path_add()Bob Copeland2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most times that mesh_path_add() is called, it is followed by a lookup to get the just-added mpath. We can instead just return the new mpath in the case that we allocated one (or the existing one if already there), so do that. Also, reorder the code in mesh_path_add a bit so that we don't need to allocate in the pre-existing case.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

That leaves inconsistent state: cfg80211 thinks it's connected while mac80211 thinks it's not. Typically this won't last long, as soon as mac80211 reports the new association to cfg80211 the old one goes away. If, however, the new authentication or association doesn't succeed, then cfg80211 will forever think the old one still exists and will refuse attempts to authenticate or associate with the AP it thinks it's connected to. Anders reported that this leads to it taking a very long time to reconnect to a network, or never even succeeding. I tested this with an AP hacked to never respond to auth frames, and one that works, and with just those two the system never recovers because one won't work and cfg80211 thinks it's connected to the other so refuses connections to it. To fix this, simply make mac80211 tell cfg80211 when it is no longer connected to the old AP, while authenticating or associating to a new one.

In my tests on a clean channel, the success probability of the max throughput rate often stays somewhere between 90% and 100% under load. This can cause some unnecessary switching to lower rates.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that sta_info_recalc_tim() is called consecutively without changing the station's tim bit. In such cases there is no need to call the driver's set_tim() callback. Signed-off-by: Ilan Peer <ilan.peer@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The irqsafe version ieee80211_sta_eosp_irqsafe() exists, but drivers must not mix calls to any irqsafe/non-irqsafe function. Both ath9k and iwlwifi, the likely first users of this interface, use non-irqsafe RX/TX/TX status so must also use a non-irqsafe version of this function. Since no driver uses the _irqsafe() version, remove that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | | mac80211: provide race-free 64-bit traffic countersJohannes Berg2013-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the TX bytes/packets counters race-free by keeping them per AC so concurrent TX on queues can't cause lost or wrong updates. This works since each station belongs to a single interface. While at it also make the bytes counters 64-bit. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
