In case the AP has different regulatory information than we do,
it can happen that we connect to an AP based on e.g. the world
roaming regulatory data, and then update our database with the
AP's country information disables the channel the AP is using.
If this happens on an HT AP, the bandwidth tracking code will
hit the WARN_ON() and disconnect. Since that's not very useful,
ignore the channel-disable flag in bandwidth tracking.

When a P2P GO interface goes down, cfg80211 doesn't properly
tear it down, leading to warnings later. Add the GO interface
type to the enumeration to tear it down like AP interfaces.
Otherwise, we leave it pending and mac80211's state can get
very confused, leading to warnings later.

While we're connected, the AP shouldn't change the primary channel
in the HT information. We checked this, and dropped the connection
if it did change it.
Unfortunately, this is causing problems on some APs, e.g. on the
Netgear WRT610NL: the beacons seem to always contain a bad channel
and if we made a connection using a probe response (correct data)
we drop the connection immediately and can basically not connect
properly at all.
Work around this by ignoring the HT primary channel information in
beacons if we're already connected.
Also print out more verbose messages in the other situations to
help diagnose similar bugs quicker in the future.

Samuel Ortiz <sameo@linux.intel.com> says:
'This is the second NFC fixes pull request for 3.11.
We have:
- A build failure fix for the NCI SPI transport layer due to a
missing CRC_CCITT Kconfig dependency.
- A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11
merge window but the typical terminology for loading a firmware to a
target is firmware download rather than upload. In order to avoid any
confusion in a file exported to userspace, we rename this command into
CMD_FW_DOWNLOAD."

Commit "3d9646d mac80211: fix channel selection bug" introduced a possible
infinite loop by moving the out target above the chandef_downgrade
while loop. When we downgrade to NL80211_CHAN_WIDTH_20_NOHT, we jump
back up to re-run the while loop...indefinitely. Replace goto with
break and carry on. This may not be sufficient to connect to the AP,
but will at least keep the cpu from livelocking. Thanks to Derek Atkins
as an extra pair of debugging eyes.

Currently, it is not possible to use neither NLM_F_EXCL nor
NLM_F_REPLACE from genetlink. This is due to this checking in
genl_family_rcv_msg:
if (nlh->nlmsg_flags & NLM_F_DUMP)
NLM_F_DUMP is NLM_F_MATCH|NLM_F_ROOT. Thus, if NLM_F_EXCL or
NLM_F_REPLACE flag is set, genetlink believes that you're
requesting a dump and it calls the .dumpit callback.
The solution that I propose is to refine this checking to
make it stricter:
if ((nlh->nlmsg_flags & NLM_F_DUMP) == NLM_F_DUMP)
And given the combination NLM_F_REPLACE and NLM_F_EXCL does
not make sense to me, it removes the ambiguity.
There was a patch that tried to fix this some time ago (0ab03c2
netlink: test for all flags of the NLM_F_DUMP composite) but it
tried to resolve this ambiguity in *all* existing netlink subsystems,
not only genetlink. That patch was reverted since it broke iproute2,
which is using NLM_F_ROOT to request the dump of the routing cache.

Loading a firmware into a target is typically called firmware
download, not firmware upload. So we rename the netlink API to
NFC_CMD_FW_DOWNLOAD in order to avoid any terminology confusion from

This is similar to the race Linus had reported, but in this case
it's an older bug: nl80211_prepare_wdev_dump() uses the wiphy
index in cb->args[0] as it is and thus parses the message over
and over again instead of just once because 0 is the first valid
wiphy index. Similar code in nl80211_testmode_dump() correctly
offsets the wiphy_index by 1, do that here as well.

In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev
with HCI_EV_CMD_COMPLETE as the expected completion event there is the
chance that hci_event_packet will call hci_req_cmd_complete twice (once
for the explicitly looked after event and another time in the actual
handler of cmd_complete).
In the case of __hci_cmd_sync_ev this introduces a race where the first
call wakes up the blocking __hci_cmd_sync_ev and lets it complete.
However, by the time that a second __hci_cmd_sync_ev call is already in
progress the second hci_req_cmd_complete call (from the previous
operation) will wake up the blocking function prematurely and cause it
to fail, as witnessed by the following log:

None of the BlueFRITZ! devices with manufacurer ID 31 (AVM Berlin)
support HCI_Read_Local_Supported_Commands. It is safe to use the
manufacturer ID (instead of e.g. a USB ID specific quirk) because the

John W. Linville says:
====================
This is another batch of fixes intended for the 3.11 stream. FWIW,
this is the first request with fixes from the mac80211 and iwlwifi
trees as well.
Regarding the mac80211 bits, Johannes says:
"Here I have a fix for RSSI thresholds in mesh, two minstrel fixes from
Felix, an nl80211 fix from Michal and four various fixes I did myself."
As for the iwlwifi bits, Johannes says:
"Here I have a fix for debugfs directory creation (causing a spurious
error message), two scanning fixes from David Spinadel, an LED fix and
two patches related to a BA session problem that eventually caused
firmware crashes from Emmanuel and a small BT fix for older devices as
well as a workaround for a firmware problem with APs with very small
beacon intervals from myself."
Along with those:
Arend van Spriel addresses a lock-up and a NULL pointer dereference
in brcmfmac.
Daniel Drake fixes an unhandled interrupt during device tear down
in mwifiex.
Larry Finger corrects a wil6210 build error.
Oleksij Rempel fixes two ath9k_htc problems related to keeping the
driver and firmware in sync.
Solomon Peachy gives us a cw1200 fix to avoid an oops in monitor mode.

build_skb() specifies that the data parameter must come from a kmalloc'd
area, this is only true if frag_size equals 0, because then build_skb()
will use kzsize(data) to figure out the actual data size. Update the

This patch is intended to avoid the buffering to non-assoc mesh STA
and also to avoid the triggering of frame to non-assoc mesh STA which
could cause kernel panic in specific hw.
One of the examples, is kernel panic happens to ath9k if user space
inserts the mesh STA and not proceed with the SAE and AMPE, and later
the same mesh STA is detected again. The sta_state of the mesh STA remains
at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called
and subsequently the ath_tx_aggr_wakeup, the kernel panic due to
ath_tx_node_init is not called before to initialize the require data
structures.
This issue is reported by Cedric Voncken before.

7) Add missing locking on vxlan device removal, from Stephen

8) xen-netfront has to make two passes over an SKB to prepare it for
transfer. One pass calculates the number of slots needed, the
second massages the SKB and fills the slots. Unfortunately, the
first pass doesn't calculate the number of slots properly so we
can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
work out so well. Fix from Jan Beulich with help and discussion

9) Fix a similar problem in tun and macvtap, which have to split up
scatter-gather elements at PAGE_SIZE boundaries. Don't do
zerocopy if it would result in a > MAX_SKB_FRAGS skb. Fixes from
Jason Wang.

In commit 48cc32d38a52d0b68f91a171a8d00531edc6a46e
("vlan: don't deliver frames for unknown vlans to protocols")
Florian made sure we set pkt_type to PACKET_OTHERHOST
if the vlan id is set and we could find a vlan device for this
particular id.
But we also have a problem if prio bits are set.
Steinar reported an issue on a router receiving IPv6 frames with a
vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device,
because skb->vlan_tci is set.
Forwarded frame is completely corrupted : We can see (8100:4000)
being inserted in the middle of IPv6 source address :

It seems we are not really ready to properly cope with this right now.
We can probably do better in future kernels :
vlan_get_ingress_priority() should be a netdev property instead of
a per vlan_dev one.
For stable kernels, lets clear vlan_tci to fix the bugs.

QFQ+ inherits from QFQ a design choice that may cause a high packet
delay/jitter and a severe short-term unfairness. As QFQ, QFQ+ uses a
special quantity, the system virtual time, to track the service
provided by the ideal system it approximates. When a packet is
dequeued, this quantity must be incremented by the size of the packet,
divided by the sum of the weights of the aggregates waiting to be
served. Tracking this sum correctly is a non-trivial task, because, to
preserve tight service guarantees, the decrement of this sum must be
delayed in a special way [1]: this sum can be decremented only after
that its value would decrease also in the ideal system approximated by
QFQ+. For efficiency, QFQ+ keeps track only of the 'instantaneous'
weight sum, increased and decreased immediately as the weight of an
aggregate changes, and as an aggregate is created or destroyed (which,
in its turn, happens as a consequence of some class being
created/destroyed/changed). However, to avoid the problems caused to
service guarantees by these immediate decreases, QFQ+ increments the
system virtual time using the maximum value allowed for the weight
sum, 2^10, in place of the dynamic, instantaneous value. The
instantaneous value of the weight sum is used only to check whether a
request of weight increase or a class creation can be satisfied.
Unfortunately, the problems caused by this choice are worse than the
temporary degradation of the service guarantees that may occur, when a
class is changed or destroyed, if the instantaneous value of the
weight sum was used to update the system virtual time. In fact, the
fraction of the link bandwidth guaranteed by QFQ+ to each aggregate is
equal to the ratio between the weight of the aggregate and the sum of
the weights of the competing aggregates. The packet delay guaranteed
to the aggregate is instead inversely proportional to the guaranteed
bandwidth. By using the maximum possible value, and not the actual
value of the weight sum, QFQ+ provides each aggregate with the worst
possible service guarantees, and not with service guarantees related
to the actual set of competing aggregates. To see the consequences of
this fact, consider the following simple example.
Suppose that only the following aggregates are backlogged, i.e., that
only the classes in the following aggregates have packets to transmit:
one aggregate with weight 10, say A, and ten aggregates with weight 1,
say B1, B2, ..., B10. In particular, suppose that these aggregates are
always backlogged. Given the weight distribution, the smoothest and
fairest service order would be:
A B1 A B2 A B3 A B4 A B5 A B6 A B7 A B8 A B9 A B10 A B1 A B2 ...
QFQ+ would provide exactly this optimal service if it used the actual
value for the weight sum instead of the maximum possible value, i.e.,
11 instead of 2^10. In contrast, since QFQ+ uses the latter value, it
serves aggregates as follows (easy to prove and to reproduce
experimentally):
A B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 A A A A A A A A A A B1 B2 ... B10 A A ...
By replacing 10 with N in the above example, and by increasing N, one
can increase at will the maximum packet delay and the jitter
experienced by the classes in aggregate A.
This patch addresses this issue by just using the above
'instantaneous' value of the weight sum, instead of the maximum
possible value, when updating the system virtual time. After the
instantaneous weight sum is decreased, QFQ+ may deviate from the ideal
service for a time interval in the order of the time to serve one
maximum-size packet for each backlogged class. The worst-case extent
of the deviation exhibited by QFQ+ during this time interval [1] is
basically the same as of the deviation described above (but, without
this patch, QFQ+ suffers from such a deviation all the time). Finally,
this patch modifies the comment to the function qfq_slot_insert, to
make it coherent with the fact that the weight sum used by QFQ+ can
now be lower than the maximum possible value.

Pull phase two of __cpuinit removal from Paul Gortmaker:
"With the __cpuinit infrastructure removed earlier, this group of
commits only removes the function/data tagging that was done with the
various (now no-op) __cpuinit related prefixes.
Now that the dust has settled with yesterday's v3.11-rc1, there
hopefully shouldn't be any new users leaking back in tree, but I think
we can leave the harmless no-op stubs there for a release as a
courtesy to those who still have out of tree stuff and weren't paying
attention.
Although the commits are against the recent tag to allow for minor
context refreshes for things like yesterday's v3.11-rc1~ slab content,
the patches have been largely unchanged for weeks, aside from such
trivial updates.
For detail junkies, the largely boring and mostly irrelevant history
of the patches can be viewed at:
http://git.kernel.org/cgit/linux/kernel/git/paulg/cpuinit-delete.git
If nothing else, I guess it does at least demonstrate the level of

commit 45f00f99d6e ("ipv4: tcp: clean up tcp_v4_early_demux()") added a
performance regression for non GRO traffic, basically disabling
IP early demux.
IPv6 stack resets transport header in ip6_rcv() before calling
IP early demux in ip6_rcv_finish(), while IPv4 does this only in
ip_local_deliver_finish(), _after_ IP early demux.
GRO traffic happened to enable IP early demux because transport header
is also set in inet_gro_receive()
Instead of reverting the faulty commit, we can make IPv4/IPv6 behave the
same : transport_header should be set in ip_rcv() instead of
ip_local_deliver_finish()
ip_local_deliver_finish() can also use skb_network_header_len() which is
faster than ip_hdrlen()

When priv_sta == NULL, mi->prev_sample is dereferenced too early. Move
the assignment further down, after the rate_control_send_low call.

The duplicate retransmission detection code in mac80211
erroneously attempts to do the check for every frame,
even frames that don't have a sequence control field or
that don't use it (QoS-Null frames.)
This is problematic because it causes the code to access
data beyond the end of the SKB and depending on the data
there will drop packets erroneously.
Correct the code to not do duplicate detection for such
frames.
I found this error while testing AP powersave, it lead
to retransmitted PS-Poll frames being dropped entirely
as the data beyond the end of the SKB was always zero.

RSSI threshold value used for mesh peering should be in
negative value. After range checks to mesh parameters is
introduced, this is not allowed. Fix this.

As reported in https://bugzilla.kernel.org/show_bug.cgi?id=60514,
the station loop never initialises 'sinfo' and therefore adds up
a stack values, leaking stack information (the number of times it
adds values is easily obtained another way.)
Fix this by initialising the sinfo for each station to add.

The CCK group needs special treatment to set the right flags and rate
index. Add this missing check to prevent setting broken rates for tx
packets.

When splitting the SME implementation from the MLME code,
I introduced a few bugs:
* association failures no longer sent a connect-failure event
* getting disassociated from the AP caused deauth to be sent
but state wasn't cleaned up, leading to warnings
* authentication failures weren't cleaned up properly, causing
new connection attempts to warn and fail
Fix these bugs.
