      ath10k: fix station count enforcement · cfd1061e
      由 Michal Kazior 提交于 
      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.

      ath10k: clean up num_peers locking · 292a753d
      由 Michal Kazior 提交于 
      The var was supposed to be protected by data_lock
but it wasn't so in all instances. It's actually
not necessary to have a spinlock protected
num_peers so drop it.

All instances of num_peers are already within
conf_mutex sections so use that.

      ath10k: add memory dump debugfs interface · 9f65ad25
      由 Yanbo Li 提交于 
      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

      ath10k: add register access debugfs interface · 077a3804
      由 Yanbo Li 提交于 
      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

      ath10k: fix bug reported by lockdep · 5d011f5c
      由 Sujith Manoharan 提交于 
      ath10k_tx_wep_key_work() acquires conf_mutex, so
cancelling it when conf_mutex is already taken
in ath10k_remove_interface() is incorrect, so
move it outside the lock.

      peer->keys needs to be protected by data_lock

Both install() and clear() routines for peer

      ath10k: fix shared WEP · 504f6cdf
      由 Sujith Manoharan 提交于 
      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.
