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"...
Please let me know if there are problems!

When deploying FQ pacing, one thing we noticed is that CUBIC Hystart
triggers too soon.
Having SNMP counters to have an idea of how often the various Hystart
methods trigger is useful prior to any modifications.
This patch adds SNMP counters tracking, how many time "ack train" or
"Delay" based Hystart triggers, and cumulative sum of cwnd at the time
Hystart decided to end SS (Slow Start)
myhost:~# nstat -a | grep Hystart

Allow reading of timestamps and cmsg at the same time on all relevant
socket families. One use is to correlate timestamps with egress
device, by asking for cmsg IP_PKTINFO.
on AF_INET sockets, call the relevant function (ip_cmsg_recv). To
avoid changing legacy expectations, only do so if the caller sets a
new timestamping flag SOF_TIMESTAMPING_OPT_CMSG.
on AF_INET6 sockets, IPV6_PKTINFO and all other recv cmsg are already
returned for all origins. only change is to set ifindex, which is
not initialized for all error origins.
In both cases, only generate the pktinfo message if an ifindex is
known. This is not the case for ACK timestamps.
The difference between the protocol families is probably a historical
accident as a result of the different conditions for generating cmsg
in the relevant ip(v6)_recv_error function:
ipv4: if (serr->ee.ee_origin == SO_EE_ORIGIN_ICMP) {
ipv6: if (serr->ee.ee_origin != SO_EE_ORIGIN_LOCAL) {
At one time, this was the same test bar for the ICMP/ICMP6
distinction. This is no longer true.

----
Changes
v1 -> v2
large rewrite
- integrate with existing pktinfo cmsg generation code
- on ipv4: only send with new flag, to maintain legacy behavior
- on ipv6: send at most a single pktinfo cmsg
- on ipv6: initialize fields if not yet initialized
The recv cmsg interfaces are also relevant to the discussion of
whether looping packet headers is problematic. For v6, cmsgs that
identify many headers are already returned. This patch expands
that to v4. If it sounds reasonable, I will follow with patches
1. request timestamps without payload with SOF_TIMESTAMPING_OPT_TSONLY
(http://patchwork.ozlabs.org/patch/366967/)
2. sysctl to conditionally drop all timestamps that have payload or
cmsg from users without CAP_NET_RAW.

The handling of can error states is different between platforms.
This is an attempt to correct that problem.
I've moved this handling into a generic function for changing the
error state. This ensures that error state changes are handled
the same way everywhere (where this function is used).
This new mechanism also adds reverse state transitioning in error
frames, i.e. the user will be notified through the socket interface
when the state goes down.

Netfilter updates for net-next
The following batch contains netfilter updates for net-next. Basically,
enhancements for xt_recent, skip zeroing of timer in conntrack, fix
linking problem with recent redirect support for nf_tables, ipset
updates and a couple of cleanups. More specifically, they are:
1) Rise maximum number per IP address to be remembered in xt_recent
while retaining backward compatibility, from Florian Westphal.
2) Skip zeroing timer area in nf_conn objects, also from Florian.
3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using
using meta l4proto and transport layer header, from Alvaro Neira.
4) Fix linking problems in the new redirect support when CONFIG_IPV6=n
and IP6_NF_IPTABLES=n.
And ipset updates from Jozsef Kadlecsik:
5) Support updating element extensions when the set is full (fixes
netfilter bugzilla id 880).
6) Fix set match with 32-bits userspace / 64-bits kernel.
7) Indicate explicitly when /0 networks are supported in ipset.
8) Simplify cidr handling for hash:*net* types.
9) Allocate the proper size of memory when /0 networks are supported.
10) Explicitly add padding elements to hash:net,net and hash:net,port,
because the elements must be u32 sized for the used hash function.
Jozsef is also cooking ipset RCU conversion which should land soon if
they reach the merge window in time.

When the swdev device learns a new mac/vlan on a port, it sends some async
notification to the driver and the driver installs an FDB in the device.
To give a holistic system view, the learned mac/vlan should be reflected
in the bridge's FBD table, so the user, using normal iproute2 cmds, can view
what is currently learned by the device. This API on the bridge driver gives
a way for the swdev driver to install an FBD entry in the bridge FBD table.
(And remove one).
This is equivalent to the device running these cmds:
bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master
This patch needs some extra eyeballs for review, in paricular around the
locking and contexts.

This driver is very similar to the macvlan driver except that it
uses L3 on the frame to determine the logical interface while
functioning as packet dispatcher. It inherits L2 of the master
device hence the packets on wire will have the same L2 for all
the packets originating from all virtual devices off of the same
master device.
This driver was developed keeping the namespace use-case in
mind. Hence most of the examples given here take that as the
base setup where main-device belongs to the default-ns and
virtual devices are assigned to the additional namespaces.
The device operates in two different modes and the difference
in these two modes in primarily in the TX side.
(a) L2 mode : In this mode, the device behaves as a L2 device.
TX processing upto L2 happens on the stack of the virtual device
associated with (namespace). Packets are switched after that
into the main device (default-ns) and queued for xmit.
RX processing is simple and all multicast, broadcast (if
applicable), and unicast belonging to the address(es) are
delivered to the virtual devices.
(b) L3 mode : In this mode, the device behaves like a L3 device.
TX processing upto L3 happens on the stack of the virtual device
associated with (namespace). Packets are switched to the
main-device (default-ns) for the L2 processing. Hence the routing
table of the default-ns will be used in this mode.
RX processins is somewhat similar to the L2 mode except that in
this mode only Unicast packets are delivered to the virtual device
while main-dev will handle all other packets.
The devices can be added using the "ip" command from the iproute2
package -
ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ]

* 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:

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

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
