* mac80211: close AP_VLAN interfaces before unregistering allJohannes Berg2013-07-25
| | | | | | | | | | | | | | | | | | | | commit 4c8a9d4bfaf7dbc7d2168494904d79d22cc01db7 upstream. 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.

* mac80211: abort CAC in stop_ap()Simon Wunderlich2013-06-12
| | | | | | | | | | 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.

* mac80211: work around broken APs not including HT infoJohannes Berg2013-06-12
| | | | | | | | | | | | | | | | | | | | 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.

* mac80211: Allow single vif mac address change with addr_maskHelmut Schaa2013-05-27
| | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: assign AP_VLAN hw queues correctlyJohannes Berg2013-05-27
| | | | | | | | | | | | | | 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.

* mac80211: fix queue handling crashJohannes Berg2013-05-23
| | | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: fix HT beacon-based channel switch handlingJohannes Berg2013-05-16
| | | | | | | | | | | | | | | | 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.)

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support extended channel switch when the operating class is one of the global operating classes as defined in Annex E of 802.11-2012. If it isn't, disconnect from the AP instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | | mac80211: unify CSA action frame/beacon processingJohannes Berg2013-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CSA action frame content should be processed as variable IEs rather than fixed to make it extensible. Unify the code and process them just like CSA in beacons to make it easier to extend for HT/VHT. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | | mac80211: use second center_freq segment only in 80+80Johannes Berg2013-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The field is otherwise reserved, so we shouldn't read and reject it, though any sane system will probably have to set it to 0 anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | | mac80211: always pick a basic rate to tx RTS/CTS for pre-HT ratesKarl Beldan2013-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the 1st rate control entry is a pre-HT rate we want to set rts_cts_rate_idx "as the fastest basic rate that is not faster than the data rate"(code comments). But in case some bss allowed rate indexes are lower than the lowest bss basic rate, if the rate control selects a rate among the formers for its 1st rate control entry, rts_cts_rate_idx remains 0 and is not a basic rate index. This commit sets rts_cts_rate_idx to the lowest bss basic rate index in this situation. Note that the code assumes that lowest indexes == lowest bitrates.

| * | | | mac80211: provide SSID in IBSS modeMarek Puzyniak2013-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers need SSID in AP and IBSS mode. AP SSID is provided through BSS_CHANGED_SSID notification. There was no easy way to do the same for IBSS. In IBSS mode SSID is known but was not stored in BSS configuration. Extend the AP-mode functionality to also work in IBSS mode. Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | | | mac80211: always advertise STBC/MCSes even if no AP supportJohannes Berg2013-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advertise STBC capabilities and MCS rates even if the AP doesn't support them. This has always been the right thing to do, but used to be problematic with some APs. Now WFA testing requires this so re-enable it, problematic APs would then presumably not pass the test and be fixed. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When AP interface is stopped ssid_len in the BSS configuration isn't cleared which can confuse drivers when switching modes.
