Subject: pull request: wireless 2013-12-05
Dave,
Please pull this batch of fixes intende for the 3.13 stream!
For the mac80211 bits, Johannes says:
"For now I have various fixes all over, mostly for issues introduced in
relatively recent patches. There's no real pattern to it. Some of the
issues like go back longer, but still seemed 3.13 material."
And...
"These are just two patches disabling the broken CSA code. Once this
goes into your tree I'll merge it into mac80211-next and revert there
(since we fixed the bugs there)."
For the iwlwifi bits, Emmanuel says:
"I have here a few fixes for BT Coex. One of them is a NULL pointer
dereference. Another one avoids to enable a feature that can make the
firmware unhappy since the firmware isn't ready for it yet. WE also
avoid a WARNING that can be triggered upon association in not-so-bad
cases even if the association succeeded. We add support for new NICs
(not yet on the market) and bump the API so that 3.13 will be able to
work with the new firmware that will be out soon hopefully.
I also have a boundary check from Johannes."
In addition to those...
- Arend van Spriel fixes a brcmfmac problem that could use an
uninitialized variable in an error path.
- Borislav Petkov fixes a Kconfig-based build breakage problem for
brcmsmac.
- Michal Nazarewicz fixes a couple of NULL pointer dereference problems
in ath9k and wcn36xx.
- Sujith Manoharan fixes a couple of ath9k problems related to
incorrect interpretation of EEPROM configuration data.
- Ujjal Roy fixes a memory leak in mwifiex.
Please let me know if there are problems!
Thanks,
John
