2014-11-26cfg80211: clean up beacon loss CQM eventJohannes Berg

2014-11-26ath10k: fix station count enforcementMichal Kazior
The number of peers isn't directly translatable to the number of stations because ath10k needs to reserve a few extra peers for special cases like multi-vif concurrency. The previous limit was 126 and 15 stations in AP mode for 10.x and main firmware branches respectively. The limit is now 128 and 16 which was the original intention.

2014-11-26ath10k: add memory dump debugfs interfaceYanbo Li
Add mem_val debugfs file for dumping the firmware (target) memory and also for writing to the memory. The firmware memory is accessed through one file which uses position of the file as the firmware memory address. For example, with dd use skip parameter for the address. Beucase target memory width is 32 bits it's strongly recommended to use blocksize divisable with 4 when using this interface. For example, when using dd use bs=4 to set the block size to 4 and remember to divide both count and skip values with four. To read 4 kB chunk from address 0x400000: dd if=mem_value bs=4 count=1024 skip=1048576 | xxd -g1 To write value 0x01020304 to address 0x400400: echo 0x01020304 | xxd -r | dd of=mem_value bs=4 seek=1048832 To read 4 KB chunk of memory and then write back after edit: dd if=mem_value of=tmp.bin bs=4 count=1024 skip=1048576 emacs tmp.bin dd if=tmp.bin of=mem_value bs=4 count=1024 seek=1048576 Signed-off-by: Yanbo Li <yanbol@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-11-26ath10k: add register access debugfs interfaceYanbo Li
Debugfs files reg_addr and reg_val are used for reading and writing to the firmware (target) registers. reg_addr contains the address to be accessed, which also needs to be set first, and reg_value is when used for reading and writing the actual value in ASCII. To read a value from the firmware register 0x100000: # echo 0x100000 > reg_addr # cat reg_value 0x00100000:0x000002d3 To write value 0x2400 to address 0x100000: # echo 0x100000 > reg_addr # echo 0x2400 > reg_value # Signed-off-by: Yanbo Li <yanbol@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-11-26ath10k: fix shared WEPSujith Manoharan
When static keys are used in shared WEP, when a station is associated, message 3 is sent with an encrypted payload. But, for subsequent authentications that are triggered without a deauth, the auth frame is decrypted by the HW. To handle this, check if the WEP keys have already been set for the peer and if so, mark the frame as decrypted. This scenario can happen when a station changes its default TX key and initiates a new authentication sequence.

With P2P concurrency requested hw roc duration time can be very small. Some firmware revisions refuse scan requests with too small channel dwell time.

It appears it takes more than just setting the hardware's chainmask to make things work well. Without this patch, a vdev would only use 1x1 rates when chainmask was set to 0x3.

2014-11-24net: wireless: rtlwifi: Do not always include drivers in obj-mAndreas Ruprecht
In four of the rtlwifi drivers, the Makefile contains superfluous statements indicating the compilation of the driver as an LKM regardless of the corresponding Kconfig option. If the corresponding option is set to 'y', the build system will then see the object file in obj-m and obj-y, which leads to a compilation as a built-in only. Even though this leads to the desired behavior, the unconditional appearance in obj-m is confusing for someone reading the Makefile. This patch removes the superfluous Makefile statements.
