Since nullfunc frames are transmitted as unicast frames, they're more reliable than the broadcast probe requests, so we need fewer retries to figure out whether the AP is really gone. Signed-off-by:

nullfunc frames are better for connection monitoring, because probe requests are answered even if the AP has already dropped the connection, whereas nullfunc frames from an unassociated station will trigger a disassoc/deauth frame from the AP (WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA), which allows the station to reconnect immediately instead of waiting until it attempts to transmit the next unicast frame. This only works on hardware with reliable tx ACK reporting, any other hardware needs to fall back to the probe request method. Signed-off-by:

- store the multicast rate as an index instead of the rate value (reduces cpu overhead in a hotpath) - validate the rate values (must match a bitrate in at least one sband) Signed-off-by:

Felix Fietkau authored
Check the connection by probing the AP (either using nullfunc or a probe request). If nullfunc probing is supported and the assoc is no longer valid, the AP will send a disassoc/deauth immediately. Signed-off-by:

Instead of using a fixed 2 second timeout, calculate beacon loss interval from the advertised beacon interval and a frame count. With this beacon loss happens after N (default 7) consecutive frames are missed which for a typical setup (100TU beacon interval) is ~700ms (or ~1/3 previous). Signed-off-by:

Additional comment by Larry Finger <Larry.Finger@lwfinger.net>: This change deserves a bit more explanation. You might include something like "These tables came from reverse engineering the 5.10.56.46 version of the Broadcom driver. Trace comparisons between b43 and the current Broadcom driver (5.10.120.0) show byte reversals for the PHY register writes." Signed-off-by:

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:
