2013-06-12mac80211: Fix rate control mask matching callSimon Wunderlich1-1/+1
The order of parameters was mixed up, introduced in commit "mac80211: improve the rate control API" Cc: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Mathias Kretschmer <mathias.kretschmer@fokus.fraunhofer.de> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-06-12mac80211: abort CAC in stop_ap()Simon Wunderlich1-0/+6
When a CAC is running and stop_ap is called (e.g. when hostapd is killed while performing CAC), the CAC must be aborted immediately. Otherwise ieee80211_stop_ap() will try to stop it when it's too late - wdev->channel is already NULL and the abort event can not be generated.

2013-06-12mac80211: work around broken APs not including HT infoJohannes Berg3-11/+85
There are some APs, notably 2G/3G/4G Wifi routers, specifically the "Onda PN51T", "Vodafone PocketWiFi 2", "ZTE MF60" and a similar T-Mobile branded device [1] that erroneously don't include all the needed information in (re)association response frames. Work around this by assuming the information is the same as it was in the beacon or probe response and using the data from there instead. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58881. [1] https://bbs.archlinux.org/viewtopic.php?pid=1277305 Note that this requires marking the first ieee802_11_parse_elems() argument const, otherwise we'd get a compiler warning.

2013-05-27mac80211: Allow single vif mac address change with addr_maskHelmut Schaa1-6/+20
When changing the MAC address of a single vif mac80211 will check if the new address fits into the address mask specified by the driver. This only needs to be done when using multiple BSSIDs. Hence, check the new address only against all other vifs. Also fix the MAC address assignment on new interfaces if the user changed the address of a vif such that perm_addr is not covered by addr_mask anymore.

2013-05-27mac80211: close AP_VLAN interfaces before unregistering allJohannes Berg1-0/+9
Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces") there's a bug in mac80211 when it unregisters with AP_VLAN interfaces up. If the AP_VLAN interface was registered after the AP it belongs to (which is the typical case) and then we get into this code path, unregister_netdevice_many() will crash because it isn't prepared to deal with interfaces being closed in the middle of it. Exactly this happens though, because we iterate the list, find the AP master this AP_VLAN belongs to and dev_close() the dependent VLANs. After this, unregister_netdevice_many() won't pick up the fact that the AP_VLAN is already down and will do it again, causing a crash.

2013-05-27mac80211: assign AP_VLAN hw queues correctlyJohannes Berg1-0/+3
A lot of code in mac80211 assumes that the hw queues are set up correctly for all interfaces (except for monitor) but this isn't true for AP_VLAN interfaces. Fix this by copying the AP master configuration when an AP VLAN is brought up, after this the AP interface can't change its configuration any more and needs to be brought down to change it, which also forces AP_VLAN interfaces down, so just copying in open() is sufficient.

2013-05-23mac80211: fix queue handling crashJohannes Berg1-1/+5
The code I added in "mac80211: don't start new netdev queues if driver stopped" crashes for monitor and AP VLAN interfaces because while they have a netdev, they don't have queues set up by the driver. To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame. For AP VLAN interfaces, we can do better later and actually properly track the queue status. Not doing this is really a separate bug though.

2013-05-17mac80211: fix direct probe authStanislaw Gruszka1-6/+6
We send direct probe to broadcast address, as some APs do not respond to unicast PROBE frames when unassociated. Broadcast frames are not acked, so we can not use that for trigger MLME state machine, but we need to use old timeout mechanism.

2013-05-16mac80211: fix HT beacon-based channel switch handlingJohannes Berg1-6/+22
When an HT AP is advertising channel switch in a beacon, it doesn't (and shouldn't, according to 802.11-2012 Table 8-20) include a secondary channel offset element. The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

2013-04-22mac80211: improve the rate control APIFelix Fietkau3-167/+303
Allow rate control modules to pass a rate selection table to mac80211 and the driver. This allows drivers to fetch the most recent rate selection from the sta pointer for already buffered frames. This allows rate control to respond faster to sudden link changes and it is also a step towards adding minstrel_ht support to drivers like iwlwifi. When a driver sets IEEE80211_HW_SUPPORTS_RC_TABLE, mac80211 will not fill info->control.rates with rates from the rate table (to preserve explicit overrides by the rate control module). The driver then explicitly calls ieee80211_get_tx_rates to merge overrides from info->control.rates with defaults from the sta rate table.

2013-04-17mac80211: fix station entry leak/warning while suspendingJohannes Berg1-2/+2
Since Stanislaw's patches, when suspending while connected, cfg80211 will disconnect. This causes the AP station to be removed, which uses call_rcu() to clean up. Due to needing process context, this queues a work struct on the mac80211 workqueue. This will warn and fail when already suspended, which can happen if the rcu call doesn't happen quickly. To fix this, replace the synchronize_net() which is really just synchronize_rcu_expedited() with rcu_barrier(), which unlike synchronize_rcu() waits until RCU callback have run and thus avoids this issue. In theory, this can even happen without Stanislaw's change to disconnect on suspend since userspace might disconnect just before suspending, though then it's unlikely that the call_rcu() will be delayed long enough.

However, some devices implement connection monitor offload excluding active AP probing.

2013-04-10mac80211: fix cfg80211 interaction on auth/assoc requestJohannes Berg1-4/+20
If authentication (or association with FT) is requested by userspace, mac80211 currently doesn't tell cfg80211 that it disconnected from the AP. 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.
