2008-09-24mac80211: clean up rate control APIJohannes Berg
Long awaited, hard work. This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it. It's still off better than before. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-09-15mac80211: fix virtual interfaces vs. injectionJohannes Berg
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.

2008-09-15mac80211: fix scan vs. interface removal raceJohannes Berg
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.

2008-09-15cfg80211: Add new wireless regulatory infrastructureLuis R. Rodriguez
This adds the new wireless regulatory infrastructure. 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.

2008-09-11mac80211: make conf_tx non-atomicJohannes Berg
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.

2008-07-14mac80211: fix TX sequence numbersJohannes Berg
This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

Hence, disallow it with a big warning and reduce mac80211-internal state.

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

2008-04-16mac80211: no BSS changes to driver from beacons processed during scanningReinette Chatre
There is no need to send BSS changes to driver from beacons processed during scanning. We are more interested in beacons from an AP with which we are associated - these will still be used to send updates to driver as the beacons are received without scanning. This change·removes the requirement that bss_info_changed needs to be atomic. The beacons received during scanning are processed from a tasklet, but if we do not call bss_info_changed for these beacons there is no need for it to be atomic.
