All current rate control algorithms agree to send management and no-ack frames at the lowest rate. They also agree to do this when sta and the private rate control data is NULL. We add a hlper to mac80211 for this and simplify the rate control algorithm code. Developers wishing to make enhancements to rate control algorithms are for broadcast/multicast can opt to not use this in their gate_rate() mac80211 callback. Cc: Zhu Yi <yi.zhu@intel.com> Acked-by:

This is just calling another helper, so just use the other helper directly. This should make it clear that when do not find the next rate we stick to the current one. Cc: Derek Smithies <derek@indranet.co.nz> Cc: Chittajit Mitra <Chittajit.Mitra@Atheros.com> Signed-off-by:

This is not used, and when we need to get the lowest rate we should simply use mac80211's own rate_lowest_index(sband, sta). Cc: Derek Smithies <derek@indranet.co.nz> Cc: Chittajit Mitra <Chittajit.Mitra@Atheros.com> Signed-off-by:

This has no functional change and just cleans up the code to be more legible and removes a useless variable for Multi Rate Retry. For regular frames we use 2 retries for MRR segments [0-2]. For the last MRR segment [3] we use 4. MRR[0] = 2 MRR[1] = 2 MRR[2] = 2 MRR[3] = 4 Cc: Derek Smithies <derek@indranet.co.nz> Cc: Chittajit Mitra <Chittajit.Mitra@Atheros.com> Signed-off-by:

The case where no vaid rate is found should not happen now but to help debugging and downgrade this to a warn. Signed-off-by:
-
Luis R. Rodriguez authored
When we're associated we should be able to send data to target sta. If we cannot we may be trying to use the incorrect band to talk to the sta. Lets catch any such cases, warn, and drop the frames to not invalidate assumptions being made on rate control algorithms when they have a valid sta to communicate with. Any such cases should be handled and fixed. Signed-off-by:

Add omitted mutex_unlock to one of wl12xx_op_start fail paths (when wl12xx_chip_wakeup fails). [v2] Power off the device, because: \= cite from http://marc.info/?l=linux-kernel&m=124755028209880&w=2 If the chip cannot be booted, why should it remain powered on? In some rare cases, the chip might fail to initialize, but can recover if powered off and on again, so turning it off at this point is the right thing to do. =/ Signed-off-by:

The work that we cancel there requires the cfg80211_mutex, so we can't cancel it under the mutex, which is fine, we can just move it to after the locked section. Signed-off-by:

Johannes Berg authored
In "mac80211: monitor the connection" I forgot to add code to cancel the new timers & work when the interface is brought down, which isn't a problem if you just bring it down, but _is_ a problem when you destroy the interface. Correct this lapse. Signed-off-by:

The result of container_of should not be NULL. In particular, in this case the argument to the enclosing function has passed though INIT_WORK, which dereferences it, implying that its container cannot be NULL. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ identifier fn,work,x,fld; type T; expression E1,E2; statement S; @@ static fn(struct work_struct *work) { ... when != work = E1 x = container_of(work,T,fld) ... when != x = E2 - if (x == NULL) S ... } // </smpl> Signed-off-by:

This patch roughly implements xmit aggregation for ar9170-like device. Not all AP are compatible with the driver(and firmware) yet, so YMMV. A more refined code will definitely need the final HT specification to be available for the public, lots of firmware modification and possibly a redesigned driver just for good measure. Sadly, these conditions won't come true anytime soon... Signed-off-by:

The "what-was-I-thinking-if-anything" patch. Clearly, if cfg80211_send_disassoc() does wdev_lock() and then calls __cfg80211_send_disassoc(), the latter shouldn't lock again. And the sme_state test is ... no further comments. Signed-off-by:

Implement set_tim callback for all rt2x00 drivers, this makes the device wake up powersaving stations properly while in AP mode. The only way to update the beacon is by simply calling mac80211 and requesting the new beacon. This means the set_tim() event is mostly the same as a beacon_done() event which was already defined in rt2x00lib. Signed-off-by:

When connected to a BSS, or joined to an IBSS, we'll want to know in userspace without using wireless extensions, so report the BSS status in the BSS list. Userspace can query the BSS list, display all the information and retrieve the station information as well. For example (from hwsim): $ iw dev wlan1 scan dump BSS 02:00:00:00:00:00 (on wlan1) -- associated freq: 2462 beacon interval: 100 capability: ESS ShortSlotTime (0x0401) signal: -50.00 dBm SSID: j Supported rates: 1.0* 2.0* 5.5* 11.0* 6.0 9.0 12.0 18.0 DS Paramater set: channel 11 ERP: <no flags> Extended supported rates: 24.0 36.0 48.0 54.0 Signed-off-by:

Pavel reported that you can't set the SSID from "foo" to "bar". I tried reproducing, but used different values, with different lengths, and thus never saw the obvious problem. Reported-by:

This variable is only used internally, _while_ connected. If we use it, the sequence # iwconfig wlan1 essid foo <connects> # iwconfig wlan1 essid "" <disconnects> # iwconfig will still display "foo" as the SSID afterwards, which is obviously quite bogus. Fix this by only displaying the wext SSID, if present. Signed-off-by:

There's no reason to think that hwsim has any actual signal strength, but for testing it is very useful to have it report _some_ value to the stack so I can see if the value ends up being reported correctly Signed-off-by:

Johannes Berg authored
Instead of using the wext BSSID which may be NULL if you haven't explicitly set one, we should instead use the current_bss pointer -- if that's NULL we aren't connected anyway. Fixes missing signal quality output reported to me internally at Intel. Signed-off-by:
