John W. Linville says:

====================
Please accept this pull request for the 3.10 stream...

Regarding the mac80211 bits, Johannes says:

"Here I have a bunch of minstrel fixes from Felix, per-interface
multicast filtering from Alex, set_tim debouncing from Ilan,
per-interface debugfs cleanups from Stanislaw, an error return fix from
Wei and a number of small improvements and fixes that I made myself."

And for the iwlwifi bits, Johannes says:

"Andrei changed an instance of kmalloc+memdup to kmemdup, Stanislaw
removed the now unused 5ghz_disable module parameter. I also have a
number of fixes from Ilan, Emmanuel and myself, Emmanuel also continued
working on Bluetooth coexistence."

For the sizeable batch of Bluetooth bits, Gustavo says:

"This is our first batch of patches for 3.10. The biggest changes of this pull
request are from Johan Hedberg, he implemented a HCI request framework to make
life easier when we have to send many HCI commands and a block and wait for
all of the to finish, we were able to fix a few issues in stack with the
introduction of this framework.

Other than that Dean Jenkins did a good work cleaning the RFCOMM code, the
refcnt infrastructure was removed and now we use NULL pointer checks to know
when a object was freed or not. That code was buggy and now it looks a way
better.

The rest of changes are clean ups, fixes and small improvements all over the
Bluetooth subsystem."

Regarding the wl12xx bits, Luca says:

"Some patches intended for 3.10.  Mostly bug fixes and other small
improvements."

On top of that, there are updates to brcmfmac, brcmsmac, b43, ssb and
bcma, as well as mwifiex, rt2x00, and ath9k and a few others.  The most
notable bit is the addition of a new driver in the rtlwifi family.

Please let me know if there are problems!

====================
This patch and the following two patches add support for link flap avoidance
by maintaining the link on power down. This feature is required for
management capable devices to have the management connection
uninterrupted on driver reload, reboot and interface up/down.

The other pros of this feature are
 - It speeds up boot up time by several seconds as DHCP addresses can be
   acquired faster.
 - It avoids lengthy Spanning Tree delay.

On powerup the hardware brings up the phy with default settings. If the

and starts autonegotiate. Subsequently, as long as the link is up, the
driver and management refrain from resetting and/or changing any
configuration that the link depends on.

The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is

Normally on driver load, we set the default settings for speed and flow

A second scenario is if a user changes the speed/duplex/fc settings when
the interface is down. In this case we must not pull the settings from

net: sctp: introduce uapi header for sctp

This patch introduces an UAPI header for the SCTP protocol,
so that we can facilitate the maintenance and development of
user land applications or libraries, in particular in terms
of header synchronization.

To not break compatibility, some fragments from lksctp-tools'
netinet/sctp.h have been carefully included, while taking care
that neither kernel nor user land breaks, so both compile fine
with this change (for lksctp-tools I tested with the old
netinet/sctp.h header and with a newly adapted one that includes
the uapi sctp header). lksctp-tools smoke test run through
successfully as well in both cases.

net: ipv6: only invalidate previously tokenized addresses

Instead of invalidating all IPv6 addresses with global scope
when one decides to use IPv6 tokens, we should only invalidate
previous tokens and leave the rest intact until they expire
eventually (or are intact forever). For doing this less greedy
approach, we're adding a bool at the end of inet6_ifaddr structure
instead, for two reasons: i) per-inet6_ifaddr flag space is
already used up, making it wider might not be a good idea,
since ii) also we do not necessarily need to export this
information into user space.

net: ipv6: add tokenized interface identifier support

This patch adds support for IPv6 tokenized IIDs, that allow
for administrators to assign well-known host-part addresses
to nodes whilst still obtaining global network prefix from
Router Advertisements. It is currently in draft status.

  The primary target for such support is server platforms
  where addresses are usually manually configured, rather
  than using DHCPv6 or SLAAC. By using tokenised identifiers,
  hosts can still determine their network prefix by use of
  SLAAC, but more readily be automatically renumbered should
  their network prefix change. [...]

  The disadvantage with static addresses is that they are
  likely to require manual editing should the network prefix
  in use change.  If instead there were a method to only
  manually configure the static identifier part of the IPv6
  address, then the address could be automatically updated
  when a new prefix was introduced, as described in [RFC4192]
  for example.  In such cases a DNS server might be
  configured with such a tokenised interface identifier of
  ::53, and SLAAC would use the token in constructing the
  interface address, using the advertised prefix. [...]

  http://tools.ietf.org/html/draft-chown-6man-tokenised-ipv6-identifiers-02

The implementation is partially based on top of Mark K.
Thompson's proof of concept. However, it uses the Netlink
interface for configuration resp. data retrival, so that
it can be easily extended in future. Successfully tested
by myself.

mwifiex: hold proper locks when accessing ra_list / bss_prio lists

Not locking ra_list when dequeuing packets creates race conditions.
When adding a packet 'tx_pkts_queued' is modified before setting
highest_priority_queue. If in-between the main loop starts, it will
see a packet queued (tx_pkts_queued > 0) but will not find it, since
max prio is not set yet. Depending on the scheduling, the thread
trying to add the packet could complete and restore the situation.
But this is not something to rely on.

Another race condition exists, if a new packet, exceeding current
max prio is added. If concurrently a packet is dequeued, the newly
set max prio will be overwritten with the value of the dequeued
packet. This can occur, because selecting a packet and modifying
the max prio is not atomic. The result in an infinite loop unless,
a new packet is added that has at least the priority of the hidden
packet.

Same applies to bss_prio_tbl. Forward iteration is no proper
lock-free technique and provides no protection from calls to
list_del. Although BSS are currently not added/removed dynamically,
this must not be the case in the future. Hence always hold proper
locks when accessing those lists.

mwifiex: fix infinite loop by removing NO_PKT_PRIO_TID

Using NO_PKT_PRIO_TID and tx_pkts_queued to check for an empty
state, can lead to a contradictory state, resulting in an
infinite loop. Currently queueing and dequeuing of packets is
not synchronized, and can happen concurrently. While tx_pkts_queued
is incremented when adding a packet, max prio is set to NO_PKT when
the WMM list is empty. If a packet is added right after the check
for empty, but before setting max prio to NO_PKT, that packet is
trapped and creates an infinite loop.

Because of the new packet, tx_pkts_queued is at least 1, indicating
wmm lists are not empty. Opposing that max prio is NO_PKT, which
means "skip this wmm queue, it has no packets". The infinite loop
results, because the main loop checks the wmm lists for not empty
via tx_pkts_queued, but for dequeing it uses max_prio to see if it
can skip current list. This will never end, unless a new packet is
added which will restore max prio to the level of the trapped packet.

The solution here is to rely on tx_pkts_queued solely for checking
wmm queue to be empty, and drop the NO_PKT define. It does not
address the locking issue.

6lowpan: handle dev_queue_xmit() error code properly

dev_queue_xmit() will return a positive value if the packet could not be
queued, often because the real network device (in our case the mac802154
wpan device) has its queue stopped.  lowpan_xmit() should handle the
positive return code (for the debug statement) and return that value to
the higher layer so the higher layer will retry sending the packet.

mac802154: Increase tx_buffer_len

Increase the buffer length from 10 to 300 packets. Consider that traffic on
mac802154 devices will often be 6LoWPAN, and a full-length (1280 octet)
IPv6 packet will fragment into 15 6LoWPAN fragments (because the MTU of
IEEE 802.15.4 is 127).  A 300-packet queue is really 20 full-length IPv6
packets.

With a queue length of 10, an entire IPv6 packet was unable to get queued
at one time, causing fragments to be dropped, and making reassembly
impossible.

mac802154: Use netif flow control

Use netif_stop_queue() and netif_wake_queue() to control the flow of
packets to mac802154 devices.  Since many IEEE 802.15.4 devices have no
output buffer, and since the mac802154 xmit() function is designed to
block, netif_stop_queue() is called after each packet.

mac802154: Do not try to resend failed packets

When ops->xmit() fails, drop the packet. Devices which support hardware
ack and retry (which include all devices currently supported by mainline),
will automatically retry sending the packet (in the hardware) up to 3
times, per the 802.15.4 spec.  There is no need, and it is incorrect to
try to do it in mac802154.
