We already set a station to be associated when peering completes, both
in user space and in the kernel. Thus we should always have an
associated sta before sending data frames to that station.
Failure to check assoc state can cause crashes in the lower-level driver
due to transmitting unicast data frames before driver sta structures
(e.g. ampdu state in ath9k) are initialized. This occurred when
forwarding in the presence of fixed mesh paths: frames were transmitted
to stations with whom we hadn't yet completed peering.

When processing a PREQ or PREP it's critical to use the incoming SN. If
that is improperly done routing loops and other types of badness can
happen. But the code was always processing path messages for deactivated
paths. This path fixes that so that if we have a valid SN then we use it
to verify that it is a message we can accept. For reference the relevant
section of the standard is 13.10.8.4 which doesn't address the deactivated
path case at all.
I also included a special case for when our peer reboots or restarts
networking. This is an important case because without it there can be a
very long delay before we accept path messages from that peer. It's also a
simple case and intimately associated with processing messages for
deactivated paths so I used one patch instead of two.

The 2012 spec mentions that path SNs can be invalid when created (see
section 13.10.8.4 table 13-9) but AFAICT never talks about invalidating
SNs. Which makes sense: if we have figured out the path to a target at a
certain SN then we want to remember that fact. Failing to do so can lead
to routing loops because if we don't have a valid SN then we have no way
of knowing whether an incoming path message leads to or away from the
target.
However currently when discovery fails we zero out mpath->flags which
clears MESH_PATH_SN_VALID. This patch fixes that so that only the
discovery relevant flags are cleared.

When the nexthop is unable to resolve its own nexthop it will send back a
PERR with a zero target_sn. According to section 13.10.11.4.3 step b in the
2012 standard that perr should be forwarded and the associated mpath->sn
should be incremented. Neither one of those was happening which is rather
bad because the originator was not told that packets are black holing.

Define a station chandef, to be used for wider-bw TDLS peers. When both
peers support the feature, upgrade the channel bandwidth to the maximum
allowed by both peers and regulatory. Currently widths up to 80MHz are
supported in the 5GHz band.
When a TDLS peer connects/disconnects recalculate the channel type of the
current chanctx.
Make the chanctx width calculation consider wider-bw TDLS peers and
similarly fix the max_required_bw calculation for the chanctx min_def.
Since the sta->bandwidth is calculated only later on, take
bss_conf.chandef.width as the minimal width for station interface.
Set the upgraded channel width in the VHT-operation set during TDLS setup.

Allow a device to specify support for the TDLS wider-bandwidth feature.
Indicate this support during TDLS setup in the ext-capab IE and set an
appropriate station flag when our TDLS peer supports it.
This feature gives TDLS peers the ability to use a wider channel than
the base width of the BSS. For instance VHT capable TDLS peers connected
on a 20MHz channel can extend the channel to 80MHz, if regulatory
considerations allow it.
Do not cap the bandwidth of such stations by the current BSS channel width
in mac80211.

When there are multiple RX queues, the PN checks in mac80211 cannot be
used since packets might be processed out of order on different CPUs.
Allow the driver to report that the PN has been checked, drivers that
will use multi-queue RX will have to set this flag.
For now, the flag is only valid when the frame has been decrypted, in
theory that restriction doesn't have to be there, but in practice the
hardware will have decrypted the frame already.

When introducing multiple RX queues, a single NAPI struct will not
be sufficient. Instead of trying to store multiple, simply change
the API to have the NAPI struct passed to the RX function. This of
course means that drivers using rx_irqsafe() cannot use NAPI, but
that seems a reasonable trade-off, particularly since only two of
all drivers are currently using it at all.
While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag
again since this code path cannot have a napi struct anyway.

If the hardware is unregistered while interfaces are up, mac80211 will
unregister all interfaces, which in turns causes mac80211 to be called
again to remove them all from the driver and eventually shut down the
hardware.
During this shutdown, however, it's currently already unsafe to iterate
the list of interfaces atomically, as the list is manipulated in an
unsafe manner. This puts an undue burden on the driver - it must stop
all its activities before calling ieee80211_unregister_hw(), while in
the normal stop path it can do all cleanup in the stop method. If, for
example, it's using the iteration during RX for some reason, it would
have to stop RX before unregistering to avoid crashes.
Fix this problem by closing all interfaces before unregistering them.
This will cause the driver stop to have completed before we manipulate
the interface list, and after the driver is stopped *and* has called
ieee80211_unregister_hw() it really musn't be iterating any more as
the memory will be freed as well.

If for any reason we're in the middle of PS-polling or awake after
TX due to dynamic powersave while going to suspend, go back to save
power. This might cause a response frame to get lost, but since we
can't really wait for it while going to suspend that's still better
than not enabling powersave which would cause higher power usage
during (and possibly even after) suspend.
Note that this really only affects the very few drivers that use
the powersave implementation in mac80211.

When acting as AP and a PS-Poll frame is received
associated station is marked as one in a Service
Period. This state is kept until Tx status for
released frame is reported. While a station is in
Service Period PS-Poll frames are ignored.
However if PS-Poll was received during A-MPDU
teardown it was possible to have the to-be
released frame re-queued back to pending queue.
In such case the frame was stripped of 2 important
flags:
(a) IEEE80211_TX_CTL_NO_PS_BUFFER
(b) IEEE80211_TX_STATUS_EOSP
Stripping of (a) led to the frame that was to be
released to be queued back to ps_tx_buf queue. If
station remained to use only PS-Poll frames the
re-queued frame (and new ones) was never actually
transmitted because mac80211 would ignore
subsequent PS-Poll frames due to station being in
Service Period. There was nothing left to clear
the Service Period bit (no xmit -> no tx status ->
no SP end), i.e. the AP would have the station
stuck in Service Period. Beacon TIM would
repeatedly prompt station to poll for frames but
it would get none.
Once (a) is not stripped (b) becomes important
because it's the main condition to clear the
Service Period bit of the station when Tx status
for the released frame is reported back.
This problem was observed with ath9k acting as P2P
GO in some testing scenarios but isn't limited to
it. AP operation with mac80211 based Tx A-MPDU
control combined with clients using PS-Poll frames
is subject to this race.

When we calculate the checksum on the recv path, we store the
result in the skb as an optimisation in case we need the checksum
again down the line.
This is in fact bogus for the MSG_PEEK case as this is done without
any locking. So multiple threads can peek and then store the result
to the same skb, potentially resulting in bogus skb states.
This patch fixes this by only storing the result if the skb is not
shared. This preserves the optimisations for the few cases where
it can be done safely due to locking or other reasons, e.g., SIOCINQ.

Shared skbs must not be modified and this is crucial for broadcast
and/or multicast paths where we use it as an optimisation to avoid
unnecessary cloning.
The function skb_recv_datagram breaks this rule by setting peeked
without cloning the skb first. This causes funky races which leads
to double-free.
This patch fixes this by cloning the skb and replacing the skb
in the list when setting skb->peeked.

Similarly as in commit 4f7d2cdfdde7 ("rtnetlink: verify IFLA_VF_INFO
attributes before passing them to driver"), we have a double nesting
of netlink attributes, i.e. IFLA_VF_PORTS only contains IFLA_VF_PORT
that is nested itself. While IFLA_VF_PORTS is a verified attribute
from ifla_policy[], we only check if the IFLA_VF_PORTS container has
IFLA_VF_PORT attributes and then pass the attribute's content itself
via nla_parse_nested(). It would be more correct to reject inner types
other than IFLA_VF_PORT instead of continuing parsing and also similarly
as in commit 4f7d2cdfdde7, to check for a minimum of NLA_HDRLEN.
