ath9k_htc: fix NULL-deref at probe

2017-08-26T01:13:58+00:00

commit ebeb36670ecac36c179b5fb5d5c88ff03ba191ec upstream.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory beyond the endpoint array should a
malicious device lack the expected endpoints.

ath9k_htc: Add new USB ID

2017-08-26T01:13:56+00:00

commit 0088d27b78f2c0118aee82923269518616481ea0 upstream.

This device is a dongle made by Philips to enhance their TVs with wireless capabilities,
but works flawlessly on any upstream kernel, provided that the ath9k_htc module is attached to it.
It's correctly recognized by lsusb as "0471:209e Philips (or NXP) PTA01 Wireless Adapter" and the
patch has been tested on real hardware.

ath9k_htc: Add PID/VID for a Ubiquiti WiFiStation

2017-08-26T01:13:56+00:00

commit 763cbac07674a648f1377b21ca66f577c103fa9a upstream.

Roger says, Ubiquiti produce 2 versions of their WiFiStation USB adapter.  One
has an internal antenna, the other has an external antenna and
name suffix EXT.  They have separate USB ids and in distribution
openSUSE 12.2 (kernel 3.4.6), file /usr/share/usb.ids shows:

  0cf3  Atheros Communications, Inc.
       ...
       b002  Ubiquiti WiFiStation 802.11n [Atheros AR9271]
       b003  Ubiquiti WiFiStationEXT 802.11n [Atheros AR9271]

Add b002 Ubiquiti WiFiStation in the PID/VID list.

ath5k: Change led pin configuration for compaq c700 laptop

commit 7b9bc799a445aea95f64f15e0083cb19b5789abe upstream.

Commit 09c9bae26b0d3c9472cb6ae45010460a2cee8b8d ("ath5k: add led pin
configuration for compaq c700 laptop") added a pin configuration for the Compaq
c700 laptop.  However, the polarity of the led pin is reversed.  It should be
red for wifi off and blue for wifi on, but it is the opposite.  This bug was
reported in the following bug report:

ath9k: fix buffer overrun for ar9287

2016-04-30T22:05:18+00:00

commit 83d6f1f15f8cce844b0a131cbc63e444620e48b5 upstream.

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.
