ath9k: ar5008_hw_cmn_spur_mitigate: add missing mask_m & mask_p initialisation

2016-05-11T09:21:30+00:00

commit de478a61389cacafe94dc8b035081b681b878f9d upstream.

by moving common code to ar5008_hw_cmn_spur_mitigate i forgot to move
mask_m & mask_p initialisation. This coused a performance regression
on ar9281.

mwifiex: fix corner case association failure

2016-05-11T09:21:28+00:00

commit a6139b6271f9f95377fe3486aed6120c9142779b upstream.

This patch corrects the error case in association path by returning
-1. Earlier "media_connected" used to remain on in this error case
causing failure for further association attempts.

ath10k: fix pktlog in QCA99X0

2016-05-11T09:21:27+00:00

commit 53a5c9bc53ce51f65699a43c67ab167436d28083 upstream.

Currently, we are providing wrong payload data of pktlog to trace points.
Data we receive from FW through copy engine 8 contains pktlog data alone.
We don't need to parse anything in driver before handing it to trace
points.

wlcore: fix error handling in wlcore_event_fw_logger

commit 68f37e5d7a2e00306adab033fba6c3042b33e8e1 upstream.

wlcore_read/wlcore_write can return negative values so it should
be assigned to signed variable.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].

rtlwifi: Fix size of wireless mode variable

2016-05-11T09:21:25+00:00

commit 73fb270592164b1917442f8bff4c791d095ee2ef upstream.

Smatch reports the following warning:

  CHECK   drivers/net/wireless/realtek/rtlwifi/rc.c
drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)'

This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning
from ieee80211_get_tx_rates() when using 5G") now checks the wireless
mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series().
As a result, all quantities used to store the wireless mode must be u16.

This patch also reorders struct rtl_sta_info to save a little space.

commit dc386ce76dedaeeaaf006fceb6ed8cf2e20ff026 upstream.

The port_open flag is not applicable for IBSS mode. IBSS data
path was broken when port_open flag was introduced.
This patch fixes the problem by correcting the checks.

iwlwifi: mvm: fix memory leak in paging

2016-05-04T21:49:03+00:00

commit 7fdf9663261cc77a516396fec82cee8a8ea07e76 upstream.

Currently paging download buffer is freed during the
the unloading of the opmode which happens when the driver
is unloaded.

This causes a memory leak since the paging download
buffer is allocated every time we enable the
interface, so the download buffer can be allocated many
times, but only be freed once.

Free paging download buffer during disabling of the
interface.

commit 9fc515bc9e735c10cd327f05c20f5ef69474188d upstream.

IWL_INFO is not an error but still printed by default.
"can't access the RSA semaphore it is write protected" seems
worrisome but it is not really a problem.

tuntap: restore default qdisc

2016-04-20T06:45:17+00:00

[ Upstream commit 016adb7260f481168c03e09f785184d6d5278894 ]

After commit f84bb1eac027 ("net: fix IFF_NO_QUEUE for drivers using
alloc_netdev"), default qdisc was changed to noqueue because
tuntap does not set tx_queue_len during .setup(). This patch restores
default qdisc by setting tx_queue_len in tun_setup().
