iwlwifi: pcie: fix SPLC structure parsing

2016-11-26T08:54:53+00:00

commit e0d9727c111a5917a1184c71c1a8e6f78c7fc41d upstream.

The SPLC data parsing is too restrictive and was not trying find the
correct element for WiFi.  This causes problems with some BIOSes where
the SPLC method exists, but doesn't have a WiFi entry on the first
element of the list.  The domain type values are also incorrect
according to the specification.

Fix this by complying with the actual specification.

Additionally, replace all occurrences of SPLX to SPLC, since SPLX is
only a structure internal to the ACPI tables, and may not even exist.

mwifiex: correct aid value during tdls setup

2016-10-31T10:13:59+00:00

commit b64db1b252e9974a43a51ba083fa7d03e4716167 upstream.

AID gets updated during TDLS setup, but modified value isn't reflected
in "priv->assoc_rsp_buf". This causes TDLS setup failure. The problem is
fixed here.

brcmfmac: avoid potential stack overflow in brcmf_cfg80211_start_ap()

2016-10-31T10:13:58+00:00

commit ded89912156b1a47d940a0c954c43afbabd0c42c upstream.

User-space can choose to omit NL80211_ATTR_SSID and only provide raw
IE TLV data. When doing so it can provide SSID IE with length exceeding
the allowed size. The driver further processes this IE copying it
into a local variable without checking the length. Hence stack can be
corrupted and used as exploit.

rtlwifi: Fix missing country code for Great Britain

2016-10-28T07:01:26+00:00

commit 0c9d3491530773858ff9d705ec2a9c382f449230 upstream.

Some RTL8821AE devices sold in Great Britain have the country code of
0x25 encoded in their EEPROM. This value is not tested in the routine
that establishes the regulatory info for the chip. The fix is to set
this code to have the same capabilities as the EU countries. In addition,
the channels allowed for COUNTRY_CODE_ETSI were more properly suited
for China and Israel, not the EU. This problem has also been fixed.

brcmfmac: fix memory leak in brcmf_fill_bss_param

commit 23e9c128adb2038c27a424a5f91136e7fa3e0dc6 upstream.

This function is called from get_station callback which means that every
time user space was getting/dumping station(s) we were leaking 2 KiB.

brcmsmac: Initialize power in brcms_c_stf_ss_algo_channel_get()

2016-10-07T13:23:46+00:00

commit f823a2aa8f4674c095a5413b9e3ba12d82df06f2 upstream.

wlc_phy_txpower_get_current() does a logical OR of power->flags, which
presumes that power.flags was initiliazed earlier by the caller,
unfortunately, this is not the case, so make sure we zero out the struct
tx_power before calling into wlc_phy_txpower_get_current().

2016-10-07T13:23:45+00:00

commit aaab50fcea78ae3414c3afc25aae8d0603df34d0 upstream.

The function ar9003_hw_apply_minccapwr_thresh takes as second parameter not
a pointer to the channel but a boolean value describing whether the channel
is 2.4GHz or not. This broke (according to the origin commit) the ETSI
regulatory compliance on 5GHz channels.
