pull request: wireless-next 2014-12-08
Please pull this last batch of pending wireless updates for the 3.19 tree...
For the wireless bits, Johannes says:
"This time I have Felix's no-status rate control work, which will allow
drivers to work better with rate control even if they don't have perfect
status reporting. In addition to this, a small hwsim fix from Patrik,
one of the regulatory patches from Arik, and a number of cleanups and
fixes I did myself.
Of note is a patch where I disable CFG80211_WEXT so that compatibility
is no longer selectable - this is intended as a wake-up call for anyone
who's still using it, and is still easily worked around (it's a one-line
patch) before we fully remove the code as well in the future."
For the Bluetooth bits, Johan says:
"Here's one more bluetooth-next pull request for 3.19:
- Minor cleanups for ieee802154 & mac802154
- Fix for the kernel warning with !TASK_RUNNING reported by Kirill A.
Shutemov
- Support for another ath3k device
- Fix for tracking link key based security level
- Device tree bindings for btmrvl + a state update fix
- Fix for wrong ACL flags on LE links"
And...
"In addition to the previous one this contains two more cleanups to
mac802154 as well as support for some new HCI features from the
Bluetooth 4.2 specification.
From the original request:
'Here's what should be the last bluetooth-next pull request for 3.19.
It's rather large but the majority of it is the Low Energy Secure
Connections feature that's part of the Bluetooth 4.2 specification. The
specification went public only this week so we couldn't publish the
corresponding code before that. The code itself can nevertheless be
considered fairly mature as it's been in development for over 6 months
and gone through several interoperability test events.
Besides LE SC the pull request contains an important fix for command
complete events for mgmt sockets which also fixes some leaks of hci_conn
objects when powering off or unplugging Bluetooth adapters.
A smaller feature that's part of the pull request is service discovery
support. This is like normal device discovery except that devices not
matching specific UUIDs or strong enough RSSI are filtered out.
Other changes that the pull request contains are firmware dump support
to the btmrvl driver, firmware download support for Broadcom BCM20702A0
variants, as well as some coding style cleanups in 6lowpan &
ieee802154/mac802154 code.'"
For the NFC bits, Samuel says:
"With this one we get:
- NFC digital improvements for DEP support: Chaining, NACK and ATN
support added.
- NCI improvements: Support for p2p target, SE IO operand addition,
SE operands extensions to support proprietary implementations, and
a few fixes.
- NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support,
and SE IO operand addition.
- A bunch of minor improvements and fixes for STMicro st21nfcb and
st21nfca"
For the iwlwifi bits, Emmanuel says:
"Major works are CSA and TDLS. On top of that I have a new
firmware API for scan and a few rate control improvements.
Johannes find a few tricks to improve our CPU utilization
and adds support for a new spin of 7265 called 7265D.
Along with this a few random things that don't stand out."
And...
"I deprecate here -8.ucode since -9 has been published long ago.
Along with that I have a new activity, we have now better
a infrastructure for firmware debugging. This will allow to
have configurable probes insides the firmware.
Luca continues his work on NetDetect, this feature is now
complete. All the rest is minor fixes here and there."
For the Atheros bits, Kalle says:
"Only ath10k changes this time and no major changes. Most visible are:
o new debugfs interface for runtime firmware debugging (Yanbo)
o fix shared WEP (Sujith)
o don't rebuild whenever kernel version changes (Johannes)
o lots of refactoring to make it easier to add new hw support (Michal)
There's also smaller fixes and improvements with no point of listing
here."
In addition, there are a few last minute updates to ath5k,
ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210.
Also included is a pull of the wireless tree to pick-up the fixes
originally included in "pull request: wireless 2014-12-03"...

pull request: wireless-next 2014-11-21
Please pull this batch of updates intended for the 3.19 stream...
For the mac80211 bits, Johannes says:
"It has been a while since my last pull request, so we accumulated
another relatively large set of changes:
* TDLS off-channel support set from Arik/Liad, with some support
patches I did
* custom regulatory fixes from Arik
* minstrel VHT fix (and a small optimisation) from Felix
* add back radiotap vendor namespace support (myself)
* random MAC address scanning for cfg80211/mac80211/hwsim (myself)
* CSA improvements (Luca)
* WoWLAN Net Detect (wake on network found) support (Luca)
* and lots of other smaller changes from many people"
For the Bluetooth bits, Johan says:
"Here's another set of patches for 3.19. Most of it is again fixes and
cleanups to ieee802154 related code from Alexander Aring. We've also got
better handling of hardware error events along with a proper API for HCI
drivers to notify the HCI core of such situations. There's also a minor
fix for mgmt events as well as a sparse warning fix. The code for
sending HCI commands synchronously also gets a fix where we might loose
the completion event in the case of very fast HW (particularly easily
reproducible with an emulated HCI device)."
And...
"Here's another bluetooth-next pull request for 3.19. We've got:
- Various fixes, cleanups and improvements to ieee802154/mac802154
- Support for a Broadcom BCM20702A1 variant
- Lots of lockdep fixes
- Fixed handling of LE CoC errors that should trigger SMP"
For the Atheros bits, Kalle says:
"One ath6kl patch and rest for ath10k, but nothing really major which
stands out. Most notable:
o fix resume (Bartosz)
o firmware restart is now faster and more reliable (Michal)
o it's now possible to test hardware restart functionality without
crashing the firmware using hw-restart parameter with
simulate_fw_crash debugfs file (Michal)"
On top of that...both ath9k and mwifiex get their usual level of
updates. Of note is the ath9k spectral scan work from Oleksij Rempel.
I also pulled from the wireless tree in order to avoid some merge issues.
Please let me know if there are problems!

Also the current netlink interface doesn't allow to set the short_addr

pull request: wireless-next 2014-11-07
Please pull this batch of updates intended for the 3.19 stream!
For the mac80211 bits, Johannes says:
"This relatively large batch of changes is comprised of the following:
* large mac80211-hwsim changes from Ben, Jukka and a bit myself
* OCB/WAVE/11p support from Rostislav on behalf of the Czech Technical
University in Prague and Volkswagen Group Research
* minstrel VHT work from Karl
* more CSA work from Luca
* WMM admission control support in mac80211 (myself)
* various smaller fixes, spelling corrections, and minor API additions"
For the Bluetooth bits, Johan says:
"Here's the first bluetooth-next pull request for 3.19. The vast majority
of patches are for ieee802154 from Alexander Aring with various fixes
and cleanups. There are also several LE/SMP fixes as well as improved
support for handling LE devices that have lost their pairing information
(the patches from Alfonso). Jukka provides a couple of stability fixes
for 6lowpan and Szymon conformance fixes for RFCOMM. For the HCI drivers
we have one new USB ID for an Acer controller as well as a reset
handling fix for H5."
For the Atheros bits, Kalle says:
"Major changes are:
o ethtool support (Ben)
o print dev string prefix with debug hex buffers dump (Michal)
o debugfs file to read calibration data from the firmware verification
purposes (me)
o fix fw_stats debugfs file, now results are more reliable (Michal)
o firmware crash counters via debugfs (Ben&me)
o various tracing points to debug firmware (Rajkumar)
o make it possible to provide firmware calibration data via a file (me)
And we have quite a lot of smaller fixes and clean up."
For the iwlwifi bits, Emmanuel says:
"The big new thing here is netdetect which allows the
firmware to wake up the platform when a specific network
is detected. Along with that I have fixes for d3 operation.
The usual amount of rate scaling stuff - we now support STBC.
The other commit that stands out is Johannes's work on
devcoredump. He basically starts to use the standard
infrastructure he built."
Along with that are the usual sort of updates and such for ath9k,
brcmfmac, wil6210, and a handful of other bits here and there...

Currently we ensure that the skb is freed on every error path in IPHC
decompression which makes it easy to introduce skb leaks. By centralising
the skb_free into the receive function it makes future decompression routines
easier to maintain. It does come at the expense of ensuring that the skb
passed into the decompression routine must not be copied.
