* ath9k: fix misleading indentationArnd Bergmann2016-03-14
| | | | | | | | | | | | | | | | | | | | | | | A cleanup patch in linux-3.18 moved around some code in the ath9k driver and left some code to be indented in a misleading way, made worse by the addition of some new code for p2p mode, as discovered by a new gcc-6 warning: drivers/net/wireless/ath/ath9k/init.c: In function 'ath9k_set_hw_capab': drivers/net/wireless/ath/ath9k/init.c:851:4: warning: statement is indented as if it were guarded by...

* ath9k: fix buffer overrun for ar9287Arnd Bergmann2016-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | Code that was added back in 2.6.38 has an obvious overflow when accessing a static array, and at the time it was added only a code comment was put in front of it as a reminder to have it reviewed properly. This has not happened, but gcc-6 now points to the specific overflow: drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs': drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds] maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4]; ~~~~~~~~~~~~~~~~~~~~~~~~~^~~ It turns out that the correct array length exists in the local 'intercepts' variable of this function, so we can just use that instead of hardcoding '4', so this patch changes all three instances to use that variable. The other two instances were already correct, but it's more consistent this way.

The .valid flag is used later, so I'm replacing the array of structures with an array of bools. An obvious follow-up optimization would be to replace it with a bitmask and set_bit()/find_first_bit()/ find_last_bit()/... operations. However, I have not tested this patch, so I sticked to the simpler transformation that does the job of reducing the stack usage to a harmless level.

Warm Reset trigger in continuous beacon stuck for one of the customer for other chip, noticed the MAC was stuck in RTC reset. After analysis noticed DMA did not complete when RTC was put in reset. So, before resetting the MAC need to make sure there are no pending DMA transactions because this reset does not reset all parts of the chip. The 12th and 11th bit of MAC _DMA_CFG register used to do that. 12 cfg_halt_ack 0x0 0 DMA has not yet halted 1 DMA has halted 11 cfg_halt_req 0x0 0 DMA logic operates normally 1 Request DMA logic to stop so software can reset the MAC The Bit [12] of this register indicates when the halt has taken effect or not. the DMA halt IS NOT recoverable; once software sets bit [11] to request a DMA halt, software must wait for bit [12] to be set and reset the MAC.

* ath9k: feeding entropy in kernel from ADC captureMiaoqing Pan2015-12-11
| | | | | | | | | | | | | | | | | | | | This patch is derived from commit 6301566e0b2d ("ath9k: export HW random number generator"), We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x, and AR9340, and it has sufficient quality random data (at least 10 bits and up to 22 bits of min-entropy for a 32-bit value). We conservatively assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up the pool as soon as the entropy counter becomes 896/4096 (set by random.c). Since ADC was not designed to be a dedicated HW RNG, we do not want to bind it to /dev/hwrng framework directly. This patch feeds the entropy directly from the WiFi driver to the input pool. The ADC register output is only used as a seed for the Linux entropy pool. No conditioning is needed, since all the conditioning is performed by the pool itself.

| | | | | | | | | | | | | | | | | The three eeprom implementations had quite some duplicate code when it came to endianness swapping. Additionally there was a bug in eeprom_4k and eeprom_9287 which prevented the endianness swapping from working correctly, because the swapping code was guarded within an "if (!ath9k_hw_use_flash(ah))". In eeprom_def this check did not exist, so it seems that eeprom_def was the only implementation where endianness swapping worked. This patch takes the duplicate code and moves it from eeprom_* to eeprom.c. The new code is derived from eeprom_def, while taking into account the specifics from the other implementations.

It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

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.

| * | ath9k: fix QCA9561 XLNA rxgain initialMiaoqing Pan2015-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small bugfix for commit ede6a5e7b859 ("ath9k: Add QCA956x HW support"). I guess I would have skipped renaming (that initial QCA956x commit has been there already for almost a year with the "5g" in the name) and move the call outside AR_SREV_9462_20_OR_LATER() to make it reachable.

| * | ath9k: Fix NF CCA limits for AR9287 and AR9227Martin Blumenstingl2015-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips. Using the same values in ath9k results in much better throughput for me. Before this patch I had a huge amount of packet loss (sometimes up to 40%) and the max transfer speed was somewhere around 5Mbit/s. With this patch applied I have zero packet loss and ten times the throughput. My device uses a AR9227 which is the PCI variant of the AR9287.

| * | ath9k: declare required extra tx headroomFelix Fietkau2015-09-26
| |/ | | | | | | | | | | | | | | | | | | ath9k inserts padding between the 802.11 header and the data area (to align it). Since it didn't declare this extra required headroom, this led to some nasty issues like randomly dropped packets in some setups.
