Merge branch 'for-davem' of git://git./linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
This pull request is intended for the 3.8 stream. It is a bit large
-- I guess Thanksgiving got me off track! At least the code got to
spend some time in linux-next... :-)
This includes the usual batch of pulls for Bluetooth, NFC, and mac80211
as well as iwlwifi. Also here is an ath6kl pull, and a new driver
in the rtlwifi family. The brcmfmac, brcmsmac, ath9k, and mwl8k get
their usual levels of attention, and a handful of other updates tag
along as well.
For more detail on the pulls, please see below...
On Bluetooth, Gustavo says:
"Another set of patches for integration in wireless-next. There are two big set
of changes in it: Andrei Emeltchenko and Mat Martineau added more patches
towards a full Bluetooth High Speed support and Johan Hedberg improve the
single mode support for Bluetooth dongles. Apart from that we have small fixes
and improvements."
...and:
"A few patches to 3.8. The majority of the work here is from Andrei on the High
Speed support. Other than that Johan added support for setting LE advertising
data. The rest are fixes and clean ups and small improvements like support for
a new broadcom hardware."
On mac80211, Johannes says:
"This is for mac80211, for -next (3.8). Plenty of changes, as you can see
below. Some fixes for previous changes like the export.h include, the
beacon listener fix from Ben Greear, etc. Overall, no exciting new
features, though hwsim does gain channel context support for people to
try it out and look at."
...and...:
"This one contains the mac80211-next material. Apart from a few small new
features and cleanups I have two fixes for the channel context code. The
RX_END timestamp support will probably be reworked again as Simon Barber
noted the calculations weren't really valid, but the discussions there
are still going on and it's better than what we had before."
...and:
"Please pull (see below) to get the following changes:
* a fix & a debug aid in IBSS from Antonio,
* mesh cleanups from Marco,
* a few bugfixes for some of my previous patches from Arend and myself,
* and the big initial VHT support patchset"
And on iwlwifi, Johannes says:
"In addition to the previous four patches that I'm not resending,
we have a number of cleanups, message reduction, firmware error
handling improvements (yes yes... we need to fix them instead)
and various other small things all over."
...and:
"In his quest to try to understand the current iwlwifi problems (like
stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm
including his changes in this pull request. Other than that I only have
a small cleanup from Sachin Kamat to remove a duplicate include and a
bugfix to turn off MFP if software crypto is enabled, but this isn't
really interesting as MFP isn't supported right now anyway."
On NFC, Samuel says:
"With this one we have:
- A few HCI improvements in preparation for an upcoming HCI chipset support.
- A pn544 code cleanup after the old driver was removed.
- An LLCP improvement for notifying user space when one peer stops ACKing I
frames."
On ath6kl, Kalle says:
"Major changes this time are firmware recover support to gracefully
handle if firmware crashes, support for changing regulatory domain and
support for new ar6004 hardware revision 1.4. Otherwise there are just
smaller fixes or cleanups from different people."
Thats about it... :-) Please let me know if there are problems!

ip6tnl/sit: drop packet if ECN present with not-ECT
This patch reports the change made by Stephen Hemminger in ipip and gre[6] in
commit
eccc1bb8d4b4 (tunnel: drop packet if ECN present with not-ECT).
Goal is to handle RFC6040, Section 4.2:
Default Tunnel Egress Behaviour.
o If the inner ECN field is Not-ECT, the decapsulator MUST NOT
propagate any other ECN codepoint onwards. This is because the
inner Not-ECT marking is set by transports that rely on dropped
packets as an indication of congestion and would not understand or
respond to any other ECN codepoint [RFC4774]. Specifically:
* If the inner ECN field is Not-ECT and the outer ECN field is
CE, the decapsulator MUST drop the packet.
* If the inner ECN field is Not-ECT and the outer ECN field is
Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the
outgoing packet with the ECN field cleared to Not-ECT.
The patch takes benefits from common function added in net/inet_ecn.h.
Like it was done for Xin4 tunnels, it adds logging to allow detecting broken
systems that set ECN bits incorrectly when tunneling (or an intermediate
router might be changing the header). Errors are also tracked via
rx_frame_error.

bonding: in balance-rr mode, set curr_active_slave only if it is up
If all slaves of a balance-rr bond with ARP monitor are enslaved
with down link state, bond keeps down state even after slaves
go up.
This is caused by bond_enslave() setting curr_active_slave to
first slave not taking into account its link state. As
bond_loadbalance_arp_mon() uses curr_active_slave to identify
whether slave's down->up transition should update bond's link
state, bond stays down even if slaves are up (until first slave
goes from up to down at least once).
Before commit
f31c7937 "bonding: start slaves with link down for
ARP monitor", this was masked by slaves always starting in UP
state with ARP monitor (and MII monitor not relying on
curr_active_slave being NULL if there is no slave up).

ixgbe: Fix incorrect disabling of Tx hang check in case of PFC
The XOFF received statistic registers are per priority based and not per
traffic class. The ixgbe driver was incorrectly considering them to be for
each traffic class; and then disabling the "Tx hang" check for the queues
that belonged to the particular traffic class that had received PFC frames.
The above logic worked fine in scenario where the user priority and traffic
class number matched e.g. priority 0 is mapped to traffic class 0 and so on.
But, when multiple user priorities are mapped to a single traffic class or
when user priorities and traffic class numbers do not line up; the ixgbe
driver may disable the "Tx hang" check for queues belonging to a traffic
class that did not receive PFC frames and keep the "Tx hang" check enabled
for the queues that did receive the PFC frames.
This patch corrects the above in the code by considering the statistics
on a per priority basis; then getting the traffic class the user priority
belongs to and disabling the "Tx hang" check for queues that belong
to that traffic class.

atm: br2684: Fix excessive queue bloat
There's really no excuse for an additional wmem_default of buffering
between the netdev queue and the ATM device. Two packets (one in-flight,
and one ready to send) ought to be fine. It's not as if it should take
long to get another from the netdev queue when we need it.
If necessary we can make the queue space configurable later, but I don't
think it's likely to be necessary.
cf. commit
9d02daf754238adac48fa075ee79e7edd3d79ed3 (pppoatm: Fix
excessive queue bloat) which did something very similar for PPPoATM.
Note that there is a tremendously unlikely race condition which may
result in qspace temporarily going negative. If a CPU running the
br2684_pop() function goes off into the weeds for a long period of time
after incrementing qspace to 1, but before calling netdev_wake_queue()...
and another CPU ends up calling br2684_start_xmit() and *stopping* the
queue again before the first CPU comes back, the netdev queue could
end up being woken when qspace has already reached zero.
An alternative approach to coping with this race would be to check in
br2684_start_xmit() for qspace==0 and return NETDEV_TX_BUSY, but just
using '> 0' and '< 1' for comparison instead of '== 0' and '!= 0' is
simpler. It just warranted a mention of *why* we do it that way...
Move the call to atmvcc->send() to happen *after* the accounting and
potentially stopping the netdev queue, in br2684_xmit_vcc(). This matters
if the ->send() call suffers an immediate failure, because it'll call
br2684_pop() with the offending skb before returning. We want that to
happen *after* we've done the initial accounting for the packet in
question. Also make it return an appropriate success/failure indication
while we're at it.
Tested by running 'ping -l 1000 bottomless.aaisp.net.uk' from within my
network, with only a single PPPoE-over-BR2684 link running. And after
setting txqueuelen on the nas0 interface to something low (5, in fact).
Before the patch, we'd see about 15 packets being queued and a resulting
latency of ~56ms being reached. After the patch, we see only about 8,
which is fairly much what we expect. And a max latency of ~36ms. On this
OpenWRT box, wmem_default is 163840.

It's not very useful to make either the DSA core or the tagging

1. Define a hidden HAVE_NET_DSA option and move the dependencies of
NET_DSA to that. While we're at it, drop the deprecated

2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA.

It does not make sense to keep a station alive if it is not authorised
at all. If IBSS/RSN is used it could also be the case that something
went wrong during the keys exchange and the stations ended up in a not
recoverable state.
By not updating last_rx we are giving the station a chance to be
deleted and to start the key exchange once again from scratch.

cfg80211: change function signature of cfg80211_get_p2p_attr()
The function cfg80211_get_p2p_attr() can fail and returns
a negative error code. However, the return type is unsigned
int. The largest positive number is determined by desired_len
variable in the function, which is u16. So changing the return
type to int to allow easy error checking. Also change the type
for the attribute to enum for improved type checking.

Earlier approach to fix this was discussed here:
lkml.org/lkml/2012/10/29/549
This is another approach to fix it. This is done by some changes in config
options, which make more sense than the earlier approach. As, atleast one
tagging option must always be selected for using net/dsa/ infrastructure, this
patch selects NET_DSA from tagging configs instead of having it as an selectable
config.

8139cp: set ring address after enabling C+ mode
This fixes (for me) a regression introduced by commit
b01af457 ("8139cp:
set ring address before enabling receiver"). That commit configured the
descriptor ring addresses earlier in the initialisation sequence, in
order to avoid the possibility of triggering stray DMA before the
correct address had been set up.
Unfortunately, it seems that the hardware will scribble garbage into the
TxRingAddr registers when we enable "plus mode" Tx in the CpCmd
register. Observed on a Traverse Geos router board.
To deal with this, while not reintroducing the problem which led to the
original commit, we augment cp_start_hw() to write to the CpCmd register
*first*, then set the descriptor ring addresses, and then finally to
enable Rx and Tx in the original 8139 Cmd register. The datasheet
actually indicates that we should enable Tx/Rx in the Cmd register
*before* configuring the descriptor addresses, but that would appear to
re-introduce the problem that the offending commit
b01af457 was trying
to solve. And this variant appears to work fine on real hardware.
