2015-11-17rtlwifi: rtl8821ae: Fix lockups on bootLarry Finger
In commit 54328e64047a5 ("rtlwifi: rtl8821ae: Fix system lockups on boot"), an attempt was made to fix a regression introduced in commit 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from all drivers"). Unfortunately, there were logic errors in that patch that prevented affected boxes from booting even after that patch was applied. The actual cause of the original problem is unknown as none of the developers have systems that are affected.

2015-11-16ath10k: poll HTT send completion when CE 5 is unusedRajkumar Manoharan
commit a70587b3389a ("ath10k: configure copy engine 5 for HTT messages") moved send completion polling under HTT Rx (CE 5) service routine. For QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead of CE 5. So send completion never be called. This is causing "failed to transmit packet, dropping: -105" errors. Fix this by processing send completion from CE 1 service routine instead of CE 5.

2015-11-15iwlwifi: mvm: don't overwrite the key indices in D3 entryLuca Coelho
When entering D3, we need to use hardcoded key indices because the firmware requires that. To do so, we are overwriting the HW key index in the keyconf structure, which makes it impossible to reuse the indices that were used before entering D3. Additionally, we overwrite all the non-PTK keys with index 1, because the firmware only allows one non-PTK key to be set. This is bad, because when we resume, we may try to set more than one key with index 1, which will obviously fail. To fix this, allow the callers to set a pre-defined index to use in iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from the keyconf struct (which requires overwriting it). In normal cases, the caller can pass STA_KEY_IDX_INVALID, which will cause a new key offset to be chosen. During HW_RESTART, we pass the offset that is in use. And during D3 entry, we pass the hardcoded indices we need to use. Additionally, don't clear the fw_key_table in D3 entry, so that the flags are still set with the pre-D3 values when exiting D3. fixes=I3165c22362483f0152d9ec1d2a987fb5529727c1 Fixes: b546dcd6b742 ("iwlwifi: mvm: don't reset key index on HW restart") Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-11-10ath10k: fix invalid NSS for 4x4 devicesRajkumar Manoharan
The number of spatial streams that are derived from chain mask for 4x4 devices is using wrong bitmask and conditional check. This is affecting downlink throughput for QCA99x0 devices. Earlier cfg_tx_chainmask is not filled by default until user configured it and so get_nss_from_chainmask never be called. This issue is exposed by recent commit 166de3f1895d ("ath10k: remove supported chain mask"). By default maximum supported chain mask is filled in cfg_tx_chainmask.

European Union has made it mandatory that all devices working in 2.4 GHz has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1) beginnig this year. The standard basically speaks about interferences in 2.4Ghz band. For example, when 802.11 device detects interference, TX must be stopped as long as interference is present. Adaptive CCA is a feature, when enabled the device learns from the environment and configures CCA levels adaptively. This will improve detecting interferences and the device can stop trasmissions till the interference is present eventually leading to good performances in varying interference conditions.

2015-10-28ssb: pick PCMCIA host code support from b43 driverRafał Miłecki
ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO. Every ssb bus contains cores AKA devices. The main idea is to have ssb driver scan/initialize bus and register ready-to-use cores. This way ssb drivers can operate on a single core mostly ignoring underlaying details. For some reason PCMCIA support was split between ssb and b43. We got PCMCIA host device probing in b43, then bus scanning in ssb and then wireless core probing back in b43. The truth is it's very unlikely we will ever see PCMCIA ssb device with no 802.11 core but I still don't see any advantage of the current architecture. With proposed change we get the same functionality with a simpler architecture, less Kconfig symbols, one killed EXPORT and hopefully cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb specific code in ssb driver. This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We already use similar solution with b43_pci_bridge.c. I didn't use "b43" in name of this new file as in theory any driver can operate on wireless core.

2015-10-28mwifiex: toggle carrier state in start_ap/stop_ap.Marty Faltesek
In uap mode the carrier is not enabled until after the first STA joins. The carrier triggers the bridge to start its state machine, and if STP is enabled, it takes 4 seconds as it transitions from disabled to forwarding. During this time the bridge drops all traffic, and the EAPOL handshake times out after 3 seconds, preventing stations from joining. Follow the logic used in mac80211 and start the carrier in start_ap and disable it in stop_ap. This has a nice benefit of allowing the first station connection time to be reduced by up to 75% when STP is in use.

2015-10-28wcn36xx: introduce per-channel ring buffer locksBob Copeland
wcn36xx implements a ring buffer for transmitted frames for each (high and low priority) DMA channel. The ring buffers are lockless: new frames are inserted at the head of the queue, while finished packets are reaped from the tail. Unfortunately, the list manipulations are missing any kind of barriers so are susceptible to various races: for example, a TX completion handler might read an updated desc->ctrl before the head has actually advanced, and then null out the ctl->skb pointer while it is still being used in the TX path. Simplify things here by adding a spin lock when traversing the ring. This change increased stability for me without adding any noticeable overhead on my platform (xperia z).

2015-10-28ath9k: fix phyerror codesZefir Kurtisi
Some of the ath9k_phyerr enums were wrong from the beginning (and even before). Most of the time the codes were used for counters to be displayed over debugfs, which made this a non-functional issue. Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used for radar detection and require the correct code to work as intended. This patch includes: a) fixes ATH9K_PHYERR_FALSE_RADAR_EXT: 24 => 36 ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28 ATH9K_PHYERR_CCK_POWER_DROP: 33 => 29 ATH9K_PHYERR_HT_CRC_ERROR: 34 => 32 ATH9K_PHYERR_HT_LENGTH_ILLEGAL: 35 => 33 ATH9K_PHYERR_HT_RATE_ILLEGAL: 36 => 34 b) extensions ATH9K_PHYERR_CCK_BLOCKER = 24 ATH9K_PHYERR_HT_ZLF = 35 ATH9K_PHYERR_GREEN_FIELD = 37 Aside from the correction and completion made in the enum, the patch also extends the display of the related counters in the debugfs.

2015-10-28orinoco_usb: return error in ezusb_probe when alloc_orinocodev failsJohn Linville
The current code exits after alloc_orinocodev, but fails to change the return value to something that indicates the failure.

2015-10-28airo: fix scan after SIOCSIWAP (airo_set_wap)Ondrej Zary
SIOCSIWAP (airo_set_wap) affects scan: only the AP specified by SIOCSIWAP is present in scan results. This makes NetworkManager work for the first time but then unable to find any other APs. Clear APList before starting scan and set it back after scan completes to work-around the problem. To avoid losing packets during scan, modify disable_MAC() to omit netif_carrier_off() call when lock == 2.

2015-10-28airo: Track APList_rid in struct airo_infoOndrej Zary
Instead of dynamically allocating APList, make it a member of struct airo_info to always track state of APList_rid. This simplifies suspend/resume and allows removal of readAPListRid. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== here's a bigger pull request for 4.4. The diffstat looks scary as we created a new directory realtek for all realtek drivers. In the future I'm planning to create similar directories for all vendors, currently we just have ath, mediatek and realtek. This change has been in linux-next for a couple of weeks so it should be safe, but of course you never know. There's also a new driver rtl8xxxu for few realtek USB devices. This just made it to the last linux-next build. Otherwise there's nothing really special, more info below. If time permits, and it's ok for you, I'm hoping to send you a one more pull request this week. brcmfmac * using netdev carrier state * add and rework some cfg80211 callbacks mainly for AP mode * use devcoredump when triggered by firmware event realtek * create new directory drivers/net/wireless/realtek/ for all realtek drivers, not visible to users (no kconfig changes etc) * add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future ath10k * add board 2 API support for automatically choosing correct board file * data path optimisations * disable PCI power save for qca988x and QCA99x0 due to interop reasons wil6210 * BlockAckReq support * firmware crashdump using devcoredump * capture all frames with sniffer ==================== Signed-off-by: David S.
