* mac80211: implement dynamic power saveKalle Valo2008-12-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add HT rates into RX status reportingJouni Malinen2008-12-191-2/+9
| | | | | | | | | | This patch adds option for HT-enabled drivers to report HT rates (HT20/HT40, short GI, MCS index) to mac80211. These rates are currently not in the rate table, so the rate_idx is used to indicate MCS index. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

* mac80211: Fix HT channel selectionSujith2008-12-191-8/+1Star
| | | | | | | | | | | | | HT management is done differently for AP and STA modes, unify to just the ->config() callback since HT is fundamentally a PHY property and cannot be per-BSS. Rename enum nl80211_sec_chan_offset as nl80211_channel_type to denote the channel type ( NO_HT, HT20, HT40+, HT40- ).

* mac80211: remove fragmentation offload functionalityJohannes Berg2008-12-121-5/+0Star
| | | | | | | | | | | | There's no driver that actually does fragmentation on the device, and the callback is buggy (when it returns an error, mac80211's fragmentation status is changed so reading the frag threshold from userspace reads the new value despite the error).

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.

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: fix virtual interfaces vs. injectionJohannes Berg2008-09-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, virtual interface pointers passed to drivers might be from monitor interfaces and as such completely uninitialised because we do not tell the driver about monitor interfaces when those are created. Instead of passing them, we should therefore indicate to the driver that there is no information; do that by passing a NULL value and adjust drivers to cope with it. As a result, some mac80211 API functions also need to cope with a NULL vif pointer so drivers can still call them unconditionally. Also, when injecting frames we really don't want to pass NULL all the time, if we know we are the source address of a frame and have a local interface for that address, we can to use that interface. This also helps with processing the frame correctly for that interface which will help the 802.11w implementation. It's not entirely correct for VLANs or WDS interfaces because there the MAC address isn't unique, but it's already a lot better than what we do now. Finally, when injecting without a matching local interface, don't assign sequence numbers at all. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: fix scan vs. interface removal raceJohannes Berg2008-09-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

The main motiviation behind this was to centralize regulatory code as each driver was implementing their own regulatory solution, and to replace the initial centralized code we have where: * only 3 regulatory domains are supported: US, JP and EU * regulatory domains can only be changed through module parameter * all rules were built statically in the kernel We now have support for regulatory domains for many countries and regulatory domains are now queried through a userspace agent through udev allowing distributions to update regulatory rules without updating the kernel. Each driver can regulatory_hint() a regulatory domain based on either their EEPROM mapped regulatory domain value to a respective ISO/IEC 3166-1 country code or pass an internally built regulatory domain. We also add support to let the user set the regulatory domain through userspace in case of faulty EEPROMs to further help compliance. Support for world roaming will be added soon for cards capable of this. For more information see: http://wireless.kernel.org/en/developers/Regulatory/CRDA For now we leave an option to enable the old module parameter, ieee80211_regdom, and to build the 3 old regdomains statically (US, JP and EU). This option is CONFIG_WIRELESS_OLD_REGULATORY. These old static definitions and the module parameter is being scheduled for removal for 2.6.29. Note that if you use this you won't make use of a world regulatory domain as its pointless. If you leave this option enabled and if CRDA is present and you use US or JP we will try to ask CRDA to update us a regulatory domain for us. Signed-off-by: Luis R.

* mac80211: make conf_tx non-atomicJohannes Berg2008-09-111-1/+1
| | | | | | | | | | | The conf_tx callback currently needs to be atomic, this requirement is just because it can be called from scanning. This rearranges it slightly to only update while not scanning (which is fine, we'll be getting beacons when associated) and thus removes the atomic requirement.

* mac80211/cfg80211: Add BSS configuration options for AP modeJouni Malinen2008-08-291-0/+9
| | | | | | | | | | | | This change adds a new cfg80211 command, NL80211_CMD_SET_BSS, to allow AP mode BSS parameters to be changed from user space (e.g., hostapd). The drivers using mac80211 are expected to be modified with separate changes to use the new BSS info parameter for short slot time in the bss_info_changed() handler.

| | | | | | | | | | | | This patch makes possible for a driver to specify maximal listen interval The possibility for user to configure listen interval is not implemented yet, currently the maximum provided by the driver or 1 is used. Mac80211 uses config handler to set listen interval for to the driver.
