* cfg80211: fix channel configuration in IBSS joinAntonio Quartulli2014-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving an IBSS_JOINED event select the BSS object based on the {bssid, channel} couple rather than the bssid only. With the current approach if another cell having the same BSSID (but using a different channel) exists then cfg80211 picks up the wrong BSS object. The result is a mismatching channel configuration between cfg80211 and the driver, that can lead to any sort of problem. The issue can be triggered by having an IBSS sitting on given channel and then asking the driver to create a new cell using the same BSSID but with a different frequency. By passing the channel to cfg80211_get_bss() we can solve this ambiguity and retrieve/create the correct BSS object. All the users of cfg80211_ibss_joined() have been changed accordingly. Moreover WARN when cfg80211_ibss_joined() gets a NULL channel as argument and remove a bogus call of the same function in ath6kl (it does not make sense to call cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

* mac80211: fix bufferable MMPDU RX handlingJohannes Berg2014-02-042-15/+9Star
| | | | | | | | | | | | | | | Action, disassoc and deauth frames are bufferable, and as such don't have the PM bit in the frame control field reserved which means we need to react to the bit when receiving in such a frame. Fix this by introducing a new helper ieee80211_is_bufferable_mmpdu() and using it for the RX path that currently ignores the PM bit in any non-data frames for doze->wake transitions, but listens to it in all frames for wake->doze transitions, both of which are wrong. Also use the new helper in the TX path to clean up the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* mac80211: send {ADD,DEL}BA on AC_VO like other mgmt frames, as per specKarl Beldan2014-02-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | ATM, {ADD,DEL}BA and BAR frames are sent on the AC matching the TID of the BA parameters. In the discussion [1] about this patch, Johannes recalled that it fixed some races with the DELBA and indeed this behavior was introduced in [2]. While [2] is right for the BARs, the part queueing the {ADD,DEL}BAs on their BA params TID AC violates the spec and is more a workaround for some drivers. Helmut expressed some concerns wrt such drivers, in particular DELBAs in rt2x00. ATM, DELBAs are sent after a driver has called (hence "purposely") ieee80211_start_tx_ba_cb_irqsafe and Johannes and Emmanuel gave some details wrt intentions behind the split of the IEEE80211_AMPDU_TX_STOP_* given to the driver ampdu_action supposed to call this function, which could prove handy to people trying to do the right thing in faulty drivers (if their fw/hw don't get in their way).

* mac80211: only set CSA beacon when at least one beacon must be transmittedLuciano Coelho2014-02-045-56/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A beacon should never have a Channel Switch Announcement information element with a count of 0, because a count of 1 means switch just before the next beacon. So, if a count of 0 was valid in a beacon, it would have been transmitted in the next channel already, which is useless. A CSA count equal to zero is only meaningful in action frames or probe_responses. Fix the ieee80211_csa_is_complete() and ieee80211_update_csa() functions accordingly. With a CSA count of 0, we won't transmit any CSA beacons, because the switch will happen before the next TBTT. To avoid extra work and potential confusion in the drivers, complete the CSA immediately, instead of waiting for the driver to call ieee80211_csa_finish(). To keep things simpler, we also switch immediately when the CSA count is 1, while in theory we should delay the switch until just before the next TBTT. Additionally, move the ieee80211_csa_finish() function to cfg.c, where it makes more sense.

| | | | | | | | | | | | | | | | | | | | | | | | | | If a uAPSD service period ends with an MMPDU, we currently just send that MMPDU, but it obviously won't get the EOSP bit set as it doesn't have a QoS header. This contradicts the standard, so add a QoS-nulldata frame after the MMPDU to properly terminate the service period with a frame that has EOSP set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a response for PS-Poll or a uAPSD trigger frame is sent, the more-data bit should be set according to 802.11-2012 11.2.1.5 h), meaning that it should indicate more data on the relevant ACs (delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.) In, for example, the following scenario: * 1 frame on VO queue (either in driver or in mac80211) * at least 1 frame on VI queue (in the driver) * both VO/VI are delivery-enabled * uAPSD trigger frame received The more-data flag to the driver would not be set, even though it should be. While fixing this, I noticed that we should really release frames from multiple ACs where there's data buffered in the driver for the corresponding TIDs. To address all this, restructure the code a bit to consider all ACs if we only release driver frames or only buffered frames. This also addresses the more-data bug described above as now the TIDs will all be marked as released, so the driver will have to check the number of frames. While at it, clarify some code and comments and remove the found variable, replacing it with the appropriate sw/hw release check.

The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).
