2014-06-25mac80211: use chanctx reservation for AP CSAMichal Kazior1-27/+55
Channel switch finalization is now 2-step. First step is when driver calls csa_finish(), the other is when reservation is actually finalized (which can be deferred for in-place reservation). It is now safe to call ieee80211_csa_finish() more than once. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-06-23mac80211: set auth flags after other station infoArik Nemtsov1-3/+13
For TDLS, the AUTHORIZED flag arrives with all other important station info (supported rates, HT/VHT caps, ...). Make sure to set the station state in the low-level driver after transferring this information to the mac80211 STA entry. This aligns the STA information during sta_state callbacks with the non-TDLS case.

2014-06-23mac80211: stop only the queues assigned to the vif during channel switchLuciano Coelho1-39/+13
Instead of stopping all the hardware queues during channel switch, which is especially bad when we have large CSA counts, stop only the queues that are assigned to the vif that is performing the channel switch. Additionally, check for (sdata->csa_block_tx) instead of calling ieee80211_csa_needs_block_tx(), which can now be removed.

2014-06-23mac80211: introduce refcount for queue_stop_reasonsLuciano Coelho1-3/+6
Sometimes different vifs may be stopping the queues for the same reason (e.g. when several interfaces are performing a channel switch). Instead of using a bitmask for the reasons, use an integer that holds a refcount instead. In order to keep it backwards compatible, introduce a boolean in some functions that tell us whether the queue stopping should be refcounted or not. For now, use not refcounted for all calls to keep it functionally the same as before. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-06-23mac80211: move csa counters from sdata to beacon/prespMichal Kazior1-23/+44
Having csa counters part of beacon and probe_resp structures makes it easier to get rid of possible races between setting a beacon and updating counters on SMP systems by guaranteeing counters are always consistent against given beacon struct. While at it relax WARN_ON into WARN_ON_ONCE to prevent spamming logs and racing.

2014-06-23cfg80211: make ethtool the driver's responsibilityJohannes Berg1-340/+0
Currently, cfg80211 tries to implement ethtool, but that doesn't really scale well, with all the different operations. Make the lower-level driver responsible for it, which currently only has an effect on mac80211. It will similarly not scale well at that level though, since mac80211 also has many drivers. To cleanly implement this in mac80211, introduce a new file and move some code to appropriate places. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-05-21mac80211: export the expected throughputAntonio Quartulli1-0/+13
Add get_expected_throughput() API to mac80211 so that each driver can implement its own version based on the RC algorithm they are using (might be using an HW RC algo). The API returns a value expressed in Kbps. Also, add the new get_expected_throughput() member to the rate_control_ops structure in order to be able to query the RC algorithm (this patch provides an implementation of this API for both minstrel and minstrel_ht). The related member in the station_info object is now filled accordingly when dumping a station.

Make the beacon CSA counters part of ieee80211_mutable_offsets and don't decrement CSA counters when generating a beacon template. This permits the driver to offload the CSA counters handling. Since mac80211 updates the probe responses with the correct counter, the driver should sync the counter's value with mac80211 using ieee80211_csa_update_counter function.

Change the type of NL80211_ATTR_CSA_C_OFF_BEACON and NL80211_ATTR_CSA_C_OFF_PRESP to be NLA_BINARY which allows userspace to use beacons and probe responses with multiple CSA counters. This isn't breaking the API since userspace can continue to use nla_put_u16 for this attributes, which is equivalent to a single element u16 array. In addition advertise max number of supported CSA counters. This is needed when using CSA and eCSA IEs together.

2014-05-06mac80211: fix CSA tx queue stoppingMichal Kazior1-13/+64
It was possible for tx queues to be stuck stopped if AP CSA finalization failed. In that case neither stop_ap nor do_stop woke the queues up. This means it was impossible to perform tx at all until driver was reloaded or a successful CSA was performed later. It was possible to solve this in a simpler manner however this is more robust and future proof (having multi-vif CSA in mind). New sdata->csa_block_tx is introduced to keep track of which interfaces requested tx to be blocked for CSA. This is required because mac80211 stops all tx queues for that purpose. This means queues must be awoken only when last tx-blocking CSA interface is finished. It is still possible to have tx queues stopped after CSA failure but as soon as offending interfaces are stopped from userspace (stop_ap or ifdown) tx queues are woken up properly.

Channel context refcount is protected by chanctx_mtx. Accessing the value without holding the mutex is racy. RCU section didn't guarantee anything here. Theoretically ieee80211_channel_switch() could fail to see refcount change and read "1" instead of, e.g. "2". This means mac80211 could accept CSA even though it shouldn't have.

2014-04-09mac80211: protect AP VLAN list with local->mtxMichal Kazior1-2/+3
It was impossible to change chanctx of master AP for AP VLANs because the copy function requires RTNL which can't be simply taken in mac80211 code due to possible deadlocks. This is required for future chanctx reservation that re-bind vifs to new chanctx. This requires safe AP VLAN iteration without RTNL. Now VLANs can be iterated while holding either RTNL or local->mtx because the list is modified while holding both of these locks.

2014-02-04mac80211: only set CSA beacon when at least one beacon must be transmittedLuciano Coelho1-30/+85
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.
