If only 3945 is selected, and is a module, build fails because iwl-legacy.c won't be compiled. Fix this by adding it to the build correctly. This doesn't happen for 4965 because it is a bool option, not tristate, since it's built into the AGN module. Reported-by:

When using AP VLAN interfaces, each VLAN interface should be in its own broadcast domain. Hostapd achieves this by assigning different GTKs to different AP VLAN interfaces. However, mac80211 drivers are not aware of AP VLAN interfaces and as such mac80211 sends the GTK to the driver in the context of the base AP mode interface. This causes problems when multiple AP VLAN interfaces are used since the driver will use the same key slot for the different GTKs (there's no way for the driver to distinguish the different GTKs from different AP VLAN interfaces). Thus, only the clients associated to one AP VLAN interface (the one that was created last) can actually use broadcast traffic. Fix this by not programming any GTKs for AP VLAN interfaces into the hw but fall back to using software crypto. The GTK for the underlying AP interface is still sent to the driver. That means, broadcast traffic to stations associated to an AP VLAN interface is encrypted in software whereas broadcast traffic to stations associated to the non-VLAN AP interface is encrypted in hardware.

When two cards are connected with the same regulatory domain if CRDA had a delayed response then cfg80211's own set regulatory domain would still be the world regulatory domain. There was a bug on cfg80211's logic such that it assumed that once you pegged a request as the last request it was already the currently set regulatory domain. This would mean we would race setting a stale regulatory domain to secondary cards which had the same regulatory domain since the alpha2 would match. We fix this by processing each regulatory request atomically, and only move on to the next one once we get it fully processed. In the case CRDA is not present we will simply world roam. This issue is only present when you have a slow system and the CRDA processing is delayed. Because of this it is not a known regression. Without this fix when a delay is present with CRDA the second card would end up with an intersected regulatory domain and not allow it to use the channels it really is designed for. When two cards with two different regulatory domains were inserted you'd end up rejecting the second card's regulatory domain request. This fails with mac80211_hswim's regtest=2 (two requests, same alpha2) and regtest=3 (two requests, different alpha2) module parameter options. This was reproduced and tested against mac80211_hwsim using this CRDA delayer: #!/bin/bash echo $COUNTRY >> /tmp/log sleep 2 /sbin/crda.orig And these regulatory tests: modprobe mac80211_hwsim regtest=2 modprobe mac80211_hwsim regtest=3 Reported-by:Mark Mentovai <mark@moxienet.com> Signed-off-by:

This will simplify the synchronization for pending requests. Without this we have a race between the core and when we restore regulatory settings, although this is unlikely its best to just avoid that race altogether. Signed-off-by:

On the disassociation event from the mac80211, the wl12xx driver does not clear the chipset configuration related to the AP - i.e. it does not perform a DISCONNECT and then a JOIN with zero SSID and dummy BSSID. Also, it does not unset the BSSID filter. Often this is not a problem, as the above is performed upon entering idle state. But if a scenario arises where a new association is attempted without cycling through idle state, the new association will fail. Fix this by resetting the firmware state on disassociation.

Extend nl80211 to report an exponential weighted moving average (EWMA) of the signal value. Since the signal value usually fluctuates between different packets, an average can be more useful than the value of the last packet. This uses the recently added generic EWMA library function.

Bruno Randolf authored
This adds generic functions for calculating Exponentially Weighted Moving Averages (EWMA). This implementation makes use of a structure which keeps the EWMA parameters and a scaled up internal representation to reduce rounding errors. The original idea for this implementation came from the rt2x00 driver (rt2x00link.c). I would like to use it in several places in the mac80211 and ath5k code and I hope it can be useful in many other places in the kernel code. Signed-off-by:

The code to handle powersaving stations has a race: when the powersave flag is lifted from a station, we could transmit a packet that is being processed for TX at the same time right away, even if there are other frames queued for it. This would cause frame reordering. To fix this, lift the flag only under the appropriate lock that blocks TX. Additionally, the code to allow drivers to block a station while frames for it are on the HW queue is never re-enabled the station, so traffic would get stuck indefinitely. Fix this by clearing the flag for this appropriately. Finally, as an optimisation, don't do anything if the driver unblocks an already unblocked station. Signed-off-by:

Some of the new AR9003 cards do not come with an external EEPROM chip anymore. Calibration data on these cards is stored in the OTP ROM on the chip. This patch adds support for reading this data, and also adds support for different EEPROM chip sizes (512 bytes instead of 1K). Signed-off-by:

Since the pointers after the rates in the tx info cannot be used anymore after frames have been queued, this area can be used to store information that was previously stored in the ath_buf. With these changes, we can delay the ath_buf assignment in the aggregation code until aggregates are formed. That will not only make it possible to simplify DMA descriptor setup to do less rewriting of uncached memory, but will also make it easier to move aggregation out of the core of the ath9k tx path.
