* cfg80211/mac80211: add mesh join/leave commandsJohannes Berg2010-12-0612-106/+322
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of tying mesh activity to interface up, add join and leave commands for mesh. Since we must be backward compatible, let cfg80211 handle joining a mesh if a mesh ID was pre-configured when the device goes up. Note that this therefore must modify mac80211 as well since mac80211 needs to lose the logic to start the mesh on interface up. We now allow querying mesh parameters before the mesh is connected, which simply returns defaults. Setting them (internally renamed to "update") is only allowed while connected. Specify them with the new mesh join command instead where needed. In mac80211, beaconing must now also follow the mesh enabled/not enabled state, which is done by testing the mesh ID.

* mac80211: speed up AP probing using nullfunc framesFelix Fietkau2010-12-063-35/+79
| | | | | | | | | | | If the nullfunc frame used to probe the AP was not acked, there is no point in waiting for the probe timeout, so advance to the next try (or disconnect) immediately. If we do reach the probe timeout without having received a tx status, the connection is probably really bad and worth disconnecting.

| | | | | | | | | | | | | | | | The last_tx_rate field was also updated for non-data frames that are often sent with a lower rate (for example management frames at 1 Mbps). This is confusing when the data rate is actually much higher. Hence, only update the last_tx_rate field with tx rate information gathered from last data frames. If the rate control algorithm filled in txrc.reported_rate we don't need to verify this information.

Saqeb Akhter reported frequent disconnects while streaming videos over samba: <http://marc.info/?m=128600031109136> > [ 1166.512087] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [ 1526.059997] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [ 2125.324356] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) > [...] The reason is that the device generates frames with slightly bogus SA/TA addresses. e.g.: [ 2314.402316] Ignore 9f:1f:31:f8:64:ff [ 2314.402321] Ignore 9f:1f:31:f8:64:ff [ 2352.453804] Ignore 0d:1f:31:f8:64:ff [ 2352.453808] Ignore 0d:1f:31:f8:64:ff ^^ the group-address flag is set! (the correct SA/TA would be: 00:1f:31:f8:64:ff) Since the AP does not know from where the frames come, it generates a DEAUTH response for the (invalid) mcast address. This mcast deauth frame then passes through all filters and tricks the stack into thinking that the AP brutally kicked us! This patch fixes the problem by simply ignoring non-broadcast, group-addressed deauth/disassoc frames.

| * | mac80211: Fix frame injection using non-AP vifJouni Malinen2010-11-291-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for frame injection to work properly for some use cases (e.g., finding the station entry and keys for encryption), mac80211 needs to find the correct sdata entry. This works when the main vif is in AP mode, but commit a2c1e3dad516618cb0fbfb1a62c36d0b0744573a broke this particular use case for station main vif. While this type of injection is quite unusual operation, it has some uses and we should fix it. Do this by changing the monitor vif sdata selection to allow station vif to be selected instead of limiting it to just AP vifs. We still need to skip some iftypes to avoid selecting unsuitable vif for injection. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Instead, it is a good idea to do a manual name request when a new connection gets created (for whatever reason) since at this point it is very cheap (no costly baseband connection creation needed just for the sake of the name request). So far userspace has been responsible for this extra name request but tighter control is needed in order not to flood Bluetooth controllers with two many commands during connection creation. It has been shown that some controllers simply fail to function correctly if they get too many (almost) simultaneous commands during connection creation. The simplest way to acheive better control of these commands is to move their sending completely to the kernel side. This patch inserts name requests into the sequence of events that the kernel performs during connection creation. It does this after the remote features have been successfully requested and before any pending authentication requests are performed. The code will work sub-optimally with userspace versions that still do the name requesting themselves (it shouldn't break anything though) so it is recommended to combine this with a userspace software version that doesn't have automated name requests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 <nbd@openwrt.org> Signed-off-by: John W.

* | | mac80211: probe the AP when resumingFelix Fietkau2010-11-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* | | mac80211: calculate beacon loss time accuratelyFelix Fietkau2010-11-242-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * | cfg80211: fix extension channel checks to initiate communicationLuis R. Rodriguez2010-11-161-0/+52
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating in a mode that initiates communication and using HT40 we should fail if we cannot use both primary and secondary channels to initiate communication. Our current ht40 allowmap only covers STA mode of operation, for beaconing modes we need a check on the fly as the mode of operation is dynamic and there other flags other than disable which we should read to check if we can initiate communication. Do not allow for initiating communication if our secondary HT40 channel has is either disabled, has a passive scan flag, a no-ibss flag or is a radar channel. Userspace now has similar checks but this is also needed in-kernel. Reported-by: Jouni Malinen <jouni.malinen@atheros.com> Cc: stable@kernel.org Signed-off-by: Luis R.
