2017-04-19ath: Fix updating radar flags for coutry code IndiaMohammed Shafi Shajakhan1-7/+12
As per latest regulatory update for India, channel 52, 56, 60, 64 is no longer restricted to DFS. Enabling DFS/no infra flags in driver results in applying all DFS related restrictions (like doing CAC etc before this channel moves to 'available state') for these channels even though the country code is programmed as 'India' in he hardware, fix this by relaxing the frequency range while applying RADAR flags only if the country code is programmed to India. If the frequency range needs to modified based on different country code, ath_is_radar_freq can be extended/modified dynamically.

2017-04-19ath9k: add noise floor override optionSimon Wunderlich3-1/+67
Introduce a debugfs option to manually override the noise floor, ignoring the automatically tuned noise floor of the driver/hw. In my tests with a AR9580 based module and a tx99 5 MHz interferer, I could tune the noisefloor to -95 dBm or above to allow communication again. The automatic noise floor calibration sometimes could adapt to the situation as well, but not reliably and permanently. I would consider this "feature" experimental and interesting for people debugging the noise floor calibration or other effects of the hardware.

For QCA6174 hw3.0, since WLAN.RM.4.4-00022-QCARMSWPZ-2, it starts to support the board ID information from otp, with some devices released on the market that didn't calibrated with OTP, will have 0 for board ID information, which cause the backward compatibility issue and was fixed in commit 'd2e202c06ca4 ("ath10k: ignore configuring the incorrect board_id")' So bump the fw api version to differentiate the latest firmware support.

2017-04-19ath10k: fix spectral scan for QCA99X0 family of chipsetsMohammed Shafi Shajakhan3-9/+32
spectral_bin length (number of bins per fft sample) is usually a value where (2^n = value), n is an integer. All of the QCA99X0 family of chipsets seems to report a spectral_bin length of 2^n + 'm' bytes, where m = 4, 12 based on the chipset. This 'm' bytes seems to carry some radar related info which is currently discarded only for 'bin_len = 68' bytes. Extend this discarding of irrelevant 'bin_len' for QCA9984, QCA9888, IPQ4019 as well by introducing a hardware parameter 'spectral_bin_discard'. Also for QCA988X based family of chipsets which doesn't seem to have this issue and also for some of the hardware which I have not tested like QCA6174/QCA9377 the existing behaviour is retained as it is.

2017-04-13wil6210: support 8KB RX buffersLior David4-5/+36
The 11ad spec requires 11ad devices to be able to receive 8KB packets over the air. Currently this is only possible by loading the driver with mtu_max=7912 but this also forces a smaller block ACK window size which reduces performance for stations which transmit normal sized packets (<2KB). Fix this problem as follows: 1. Add a module parameter rx_large_buf that when set, will allocate 8KB RX buffers regardless of mtu_max setting. 2. When receiving block ACK request agree to any window size not above our maximum, regardless of the mtu_max setting. This means if the other side transmits small packets (2KB) it can still set up block ACK with a large window size, and get better performance.

2017-04-05ath10k: fix station nss computationVenkateswara Rao Naralasetty1-0/+14
If station advertises diffferent NSS capabilities in Rx_mcs set of HT and VHT IEs in assoc req, the current NSS computation logic configures the NSS support only based on Rx_mcs set of HT capabilities in the driver. This is configuring the station NSS capabilities incorreclty in the target. For example, if station advertise Rx_mcs set as 2 spatial streams in HT capabilities and 1 spatial streams in VHT capabilities in assoc request, as per current logic we are calculating nss from HT capabilities and the driver sets peer_num_spatial_streams as 2 for the station which is configured in VHT 1*1.

Channels 34/38/42/46 can only be used for compatibility with old devices sold in Japan. Modern products, such as AR6003/AR6004 don't support these channels. Keeping them in the upstream is error prone and requires full network stack support. A custom patch should be used in case such compatibility is required. Without this one, a user is able to start an AP using wpa_supplicant, for example, on one of these channels (34/38/42/46), without getting any warning/error from the cfg80211 or ath6kl - which is correct (since these channels match regdom rules).

2017-03-16ath10k: update available channel list for 5G radioTamizh chelvam4-0/+29
If a 5 GHz radio is calibrated for operation in both the low band (channels 36 to 64) and high band(channels 100 to 169), hardware allows operations in all the listed channels. However, if the chip has been calibrated only for the low/high band and a high/low band channel is configured, due to lack of calibration there will be potentially invalid signal on those non calibrated channels. To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for those non calibrated channels by using low_5ghz_chan and high_5ghz_chan values which we get from target through wmi service ready event. Driver initialized flags are getting re initialized in handle_channel in cfg80211. So calling the function to disable the non supported channel from reg_notifier().

With this configuration (DFS disabled in hostapd) trying to bring up ath10k device in DFS channel for AP mode fails and trying to simulate DFS in ath10k debugfs results in a warning in cfg80211 complaining invalid channel and this should be avoided in the driver itself rather than false propogating RADAR detection to mac80211/cfg80211. Fix this by checking for the first vif 'is_started' state(should work for client mode as well) as all the vifs shall be configured for the same channel sys/kernel/debug/ieee80211/phy1/ath10k# echo 1 > dfs_simulate_radar WARNING: at net/wireless/chan.c:265 cfg80211_radar_event+0x24/0x60 Workqueue: phy0 ieee80211_dfs_radar_detected_work [mac80211] [<c022f2d4>] (warn_slowpath_null) from [<bf72dab8>] (cfg80211_radar_event+0x24/0x60 [cfg80211]) [<bf72dab8>] (cfg80211_radar_event [cfg80211]) from [<bf7813e0>] (ieee80211_dfs_radar_detected_work+0x94/0xa0 [mac80211]) [<bf7813e0>] (ieee80211_dfs_radar_detected_work [mac80211]) from [<c0242320>] (process_one_work+0x20c/0x32c) WARNING: at net/wireless/nl80211.c:2488 nl80211_get_mpath+0x13c/0x4cc Workqueue: phy0 ieee80211_dfs_radar_detected_work [mac80211] [<c022f2d4>] (warn_slowpath_null) from [<bf72dab8>] (cfg80211_radar_event+0x24/0x60 [cfg80211]) [<bf72dab8>] (cfg80211_radar_event [cfg80211]) from [<bf7813e0>] (ieee80211_dfs_radar_detected_work+0x94/0xa0 [mac80211]) [<bf7813e0>] (ieee80211_dfs_radar_detected_work [mac80211]) from [<c0242320>] (process_one_work+0x20c/0x32c) Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2017-03-09wil6210: correctly report locally generated disconnect in STA modeDedy Lansky4-1/+7
Driver always invoke cfg80211_disconnected() with locally_generated as false. Fix this by reporting true whenever the disconnect is triggered from upper layers (cfg80211) or from within the driver itself (reset, deinit).

2017-03-09wil6210: use WMI_DISCONNECT_CMDID upon connect timeoutDedy Lansky1-3/+27
Upon connect timeout driver invokes _wil6210_disconnect() which iterates over sta array and disconnects each connected sta. In practice, because the connection is still ongoing and because cid is not yet allocated, disconnect is not actually happening. This leaves FW in connecting state while driver is in disconnected state. To fix this, upon connect timeout, explicitly send WMI_DISCONNECT_CMDID to FW to make sure it gets disconnected.

When flush is done, pending events list is manipulated without taking the proper spinlock, which could lead to memory corruption if list is manipulated by wmi worker or by interrupt routine.

2017-03-09wil6210: store bss object and use cfg80211_connect_bss()Dedy Lansky4-5/+12
In a fast disconnect/connect sequence, cfg80211_connect_result() can fail to find the bss object which the driver is connecting to. Detailed sequence of events: * Driver is connected in STA mode * Disconnect request arrives from user space. Driver disconnects and calls cfg80211_disconnected() which adds new event to the cfg80211_wq worker thread * Connect request arrives from user space. cfg80211_connect() stores ssid/ssid_len and calls rdev_connect() * __cfg80211_disconnected() runs in worker thread and zero wdev->ssid_len * Connect succeeds. Driver calls cfg80211_connect_result() which fails to find the bss because wdev->ssid_len is zero To overcome this, upon connect request, store the bss object in the driver and upon connect completion pass it to kernel using cfg80211_connect_bss().
