2012-02-06mac80211: move managed mode station state modificationJohannes Berg
Move the station state modification right before insert, this just makes the current code more readable (you can tell that it's before insertion looking at a single screenful of code) right now, but some upcoming changes will require this.

2012-01-30rtlwifi: Convert to asynchronous firmware loadLarry Finger
This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.

2012-01-30iwlwifi: always restrict scan dwell in P2PJohannes Berg
Whenever the PAN (P2P) context is active, it has timers in the uCode that prevent sleep, so scanning can't be out of channel for more than the beacon interval programmed into the device. Before this patch, a full scan including any passive channels when P2P was active would stall forever because it wouldn't find time to execute the passive requests (for default beacon intervals of 100 TU.)

2012-01-30iwlwifi: fix uCode event tracingJohannes Berg
Fix multiple bugs in event tracing: 1) If you enable uCode tracing with the device down, it will still attempt to access the device and continuously log "MAC is in deep sleep!" errors. Fix this by only starting logging when the device is actually alive. 2) Now you can set the flag when the device is down, but logging doesn't happen when you bring it up. To fix that, start logging when the device comes alive. This means we don't log before -- we could do that but I don't need it right now. 3) For some reason we read the error instead of the event log -- use the right pointer. 4) Optimise SRAM reading of event log header. 5) Fix reading write pointer == capacity, which can happen due to racy SRAM access 6) Most importantly: fix an error where we would try to read WAY too many events (like 2^32-300) when we read the wrap counter before it is updated by the uCode -- this does happen in practice and will cause the driver to hang the machine. 7) Finally, change the timer to 10ms instead of 100ms as 100ms is too slow to capture all data with a normal event log and with 100ms the log will wrap multiple times before we have a chance to read it.

2012-01-30mac80211: Fix incorrect num_sta_ps decrement in ap_sta_ps_endHelmut Schaa
If the driver blocked this specific STA with the help of ieee80211_sta_block_awake we won't clear WLAN_STA_PS_STA later but still decrement num_sta_ps. Hence, the next data frame from this STA will trigger ap_sta_ps_end again and also decrement num_sta_ps again leading to an incorrect num_sta_ps counter. This can result in problems with powersaving clients not waking up from PS because the TIM calculation might be skipped due to the incorrect num_sta_ps counter.
