* iwmc3200wifi: hardware does not support IP checksumZhu Yi2009-07-241-1/+1

* cfg80211: treat ieee80211_regdom hints as user hintsLuis R. Rodriguez2009-07-241-16/+9Star
| | | | | | | | | | | | | | | | | | | | | We were treating ieee80211_regdom module parameter hints as core hints, this means we were not letting the user help compliance further when using the module parameter. It also meant that users with a device with a custom regulatory domain set (wiphy->custom_regulatory) using this module parameter were being stuck to the original default core static regualtory domain. We fix this by using the static cfg80211_regdomain alpha2 as the core hint and treating the module parameter separately. All iwlwifi and ath5k/ath9k/ar9170 devices which world roam set the wiphy->custom_regulatory. This change allows users using this module parameter to have it trated as a a proper user hint and not have it ignored. Signed-off-by: Luis R.

* ath9k: disable radio when all devices are marked idleLuis R. Rodriguez2009-07-243-0/+42
| | | | | | | | | | | | | This uses the new configuration changes indicated up by mac80211 when all interfaces are marked idle. We need to do a little more work as we have our own set of virtual wiphys within ath9k. Only when all virtual wiphys are inactive do we allow an idle state change for a wiphy to trigger disabling the radio. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* ath9k: Fix TX hang issue with Atheros chipsetsSenthil Balasubramanian2009-07-243-14/+50
| | | | | | | | | | | | | | | | | | | | | | | | The hardware doesn't generate interrupts in some cases and so work around this by monitoring the TX status periodically and reset the chip if required. This behavior of the hardware not generating the TX interrupts can be noticed through ath9k debugfs interrupt statistics when heavy traffic is being sent from STA to AP. One can easily see this behavior when the STA is transmitting at a higher rates. The interrupt statistics in the debugfs interface clearly shows that only RX interrupts alone being generated and TX being stuck. TX should be monitored through a timer and reset the chip only when frames are queued to the hardware but TX interrupts are not generated for the same even after one second. Also, we shouldn't remove holding descriptor from AC queue if it happens to be the only descriptor and schedule TX aggregation regarless of queue depth as it improves scheduling of AMPDUs from software to hardware queue.

* ath9k: RX stucks during heavy traffic in HT40 mode.Senthil Balasubramanian2009-07-243-30/+67
| | | | | | | | | | | | | | | | | | | | Running iperf along with p2p traffic on both TX and RX side then stop one side, then stop the other side, then start it up again, eventually the STA gets into a mode that it can not pass data at all. A hardware workaround for invalid RSSI can make FIFO write pointer to jump over read pointer, causing RX data corruption and repeated DMA. Both TX and RX works fine when the workaround is disabled. To replace the original hardware work around, software looks for frames with post delimiter CRC error and mark the RSSI invalid so that the upperlayer will not use the RSSI associated with this frame. So disable the hardware workaround by updating the appropriate registers. Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: Manipulate and report the correct RSSISenthil Balasubramanian2009-07-245-5/+54

Manipulate and report the correct RSSI to the stack. This will fix the improper signal levels reported by iwconfig iw dev wlanX station dump. Also the Link Quality reported seems to be varying (falls to zero also sometimes) when iperf is run from STA to AP. Also use the default noise floor for now as the one reported during the caliberation seems to be wrong.

* cfg80211: fix unregistrationJohannes Berg2009-07-241-5/+5
| | | | | | | | | 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 <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: cancel the connection monitor timers/workJohannes Berg2009-07-242-3/+8
| | | | | | | | | | | 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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* drivers/net: Drop unnecessary NULL testJulia Lawall2009-07-241-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Julia Lawall <julia@diku.dk> Acked-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

* cfg80211: fix disabling WPA via wext (SIOCSIWAUTH)Gábor Stefanik2009-07-241-1/+11
| | | | | | | | | cfg80211_set_wpa_version completely missed the use case when disabling WPA, considering IW_AUTH_WPA_VERSION_DISABLED an invalid argument. This caused weird error messages in wpa_supplicant. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | The DEVICE_STATE_DISABLED_RADIO_HW flag is only read but never set, it is an ancient part of one of the many versions of the rfkill implementations in rt2x00.

* ar9170: implement transmit aggregationChristian Lamparter2009-07-242-26/+634
| | | | | | | | | | | | | 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: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* cfg80211: fix more bugs in mlme handlingJohannes Berg2009-07-241-5/+3Star
| | | | | | | | | | | 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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Implement set_tim callback for all driversStefan Steuerwald2009-07-248-0/+18
| | | | | | | | | | | | | 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.
