git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== 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! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patch adds support for setting an extended address while registration a new interface.

2014-11-12ieee820154: add short_addr setting supportAlexander Aring
This patch adds support for setting short address via nl802154 framework. Also added a comment because a 0xffff seems to be valid address that we don't have a short address. This is a valid setting but we need more checks in upper layers to don't allow this address as source address. Also the current netlink interface doesn't allow to set the short_addr to 0xffff. Same for the 0xfffe short address which describes a not allocated short address. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-12ieee820154: add pan_id setting supportAlexander Aring
This patch adds support for setting pan_id via nl802154 framework. Adding a comment because setting 0xffff as pan_id seems to be valid setting. The pan_id 0xffff as source pan is invalid. I am not sure now about this setting but for the current netlink interface this is an invalid setting, so we do the same now. Maybe we need to change that when we have coordinator support and association support. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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...

2014-11-066lowpan: move skb_free from error paths in decompressionMartin Townsend
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.

This encapsulates all of the skb_copy_datagram_iovec() callers with call argument signature "skb, offset, msghdr->msg_iov, length". When we move to iov_iters in the networking, the iov_iter object will sit in the msghdr. Having a helper like this means there will be less places to touch during that transformation.
