* mac80211: implement dynamic power saveKalle Valo2008-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements dynamic power save for mac80211. Basically it means enabling power save mode after an idle period. Implementing it dynamically gives a good compromise of low power consumption and low latency. Some hardware have support for this in firmware, but some require the host to do it. The dynamic power save is implemented by adding an timeout to ieee80211_subif_start_xmit(). The timeout can be enabled from userspace with Wireless Extensions. For example, the command below enables the dynamic power save and sets the time timeout to 500 ms: iwconfig wlan0 power timeout 500m Power save now only works with devices which handle power save in firmware. It's also disabled by default and the heuristics when and how to enable is considered as a policy decision and will be left for the userspace to handle. In case the firmware has support for this, drivers can disable this feature with IEEE80211_HW_NO_STACK_DYNAMIC_PS. Big thanks to Johannes Berg for the help with the design and code.

* mac80211: enable IEEE80211_CONF_PS only when associatedKalle Valo2008-12-19
| | | | | | | | | | | | Also disable power save when disassociated. It makes no sense to have power save enabled while disassociated. iwlwifi seems to have this check in the driver, but it's better to do this in mac80211 instead.

* cfg80211/mac80211: Add 802.11d supportLuis R. Rodriguez2008-11-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds country IE parsing to mac80211 and enables its usage within the new regulatory infrastructure in cfg80211. We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by: Luis R.

| * mac80211: remove ieee80211_notify_macJohannes Berg2008-11-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before ieee80211_notify_mac() was added, it was presented with the use case of using it to tell mac80211 that the association may have been lost because the firmware crashed/reset. Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that when for some reason [1] the probe or auth times out, wpa_supplicant doesn't realise this and only tries the next AP when it runs into its own timeout, which is ten seconds, and that's quite long. Fix this by making mac80211 notify userspace that it didn't associate. [1] my wrt350n in mixed B/G/HT mode often runs into this, maybe it's because one of the antennas is broken off and for whatever reason it decides to use that antenna to transmit the response frames (auth, probe); I do see beacons fine so it's not totally broken.

Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

* mac80211: avoid "Wireless Event too big" message for assoc responseJohn W. Linville2008-10-06
| | | | | | | | | | | | | | | | | | | The association response IEs are sent to userland with an IWEVCUSTOM event, which unfortunately is limited to a little more than 100 bytes of IE information with the encoding used. Many APs send so much IE information that this message overflows. When the IWEVCUSTOM event is too large, the kernel doesn't send it to userland anyway -- better just not to send it. An attempt was made by Jouni Malinen to correct this issue by converting to use IWEVASSOCREQIE and IWEVASSOCRESPIE messages instead ("mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOM"). Unfortunately, that caused a problem due to 32-/64-bit interactions on some systems and was reverted after the 'userland ABI' rule was invoked. That leaves us with this option instead of a proper fix, at least until we move to a cfg80211-based solution. Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: fix scan vs. interface removal raceJohannes Berg2008-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | When we remove an interface, we can currently end up having a pointer to it left in local->scan_sdata after it has been set down, and then with a hardware scan the scan completion can try to access it which is a bug. Alternatively, a scan that started as a hardware scan may terminate as though it was a software scan, if the timing is just right. On SMP systems, software scan also has a similar problem, just canceling the delayed work and setting a flag isn't enough since it may be running concurrently; in this case we would also never restore state of other interfaces. This patch hopefully fixes the problems by always invoking ieee80211_scan_completed or requiring it to be invoked by the driver, I suspect the drivers that have ->hw_scan() are buggy. The bug will not manifest itself unless you remove the interface while hw-scanning which will also turn off the hw, and then add a new interface which will be unusable until you scan once.

* mac80211: make BA session handling independent of STA modeJohannes Berg2008-09-11
| | | | | | | | | | | The aggregation handling isn't dependent on anything related to our STA-mode implementation, and doesn't need to depend on it for frame processing. This patch moves the relevant code to ht.c and adds a hook in rx.c. For now, the relevant action frames are only processed in STA/IBSS modes, but that's now something we can easily change.

* mac80211: initialise queue QoS parameters at hw startJohannes Berg2008-09-11
| | | | | | | | | | When hardware is started it might be in a confused state with respect to queue QoS parameters. This patch changes mac80211 to set sane defaults right after the hardware is brought up.

* mac80211: split ieee80211_sta_def_wmm_paramsJohannes Berg2008-09-11
| | | | | | | | Cleans up the code a bit and prepares for the next patch that will use the function elsewhere. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: consolidate deauth/disassocJohannes Berg2008-09-11
| | | | | | | | | deauth and disassoc frames are completely identical so there's little point in having two functions to send them rather than one that gets a parameter. This same a bit of code size.
