Station entries can have various states, the most
important ones being auth, assoc and authorized.
This patch prepares us for telling the driver about
these states, we don't want to confuse drivers with
strange transitions, so with this we enforce that
they move in the right order between them (back and
forth); some transitions might happen before the
driver even knows about the station, but at least
runtime transitions will be ordered correctly.As a consequence, IBSS and MESH stations will now
have the ASSOC flag set (so they can transition to
AUTHORIZED), and we can get rid of a special case
in TX processing.When freeing a station, unwind the state so that
other parts of the code (or drivers later) can rely
on the transitions.Signed-off-by: Johannes Berg

We can't rely on ieee80211_select_queue() to do its job at this point
since the skb->protocol is not yet known. Instead, factor out and reuse
the queue mapping logic for injected frames.Also, to mitigate congestion, forwarded frames should be dropped if the
outgoing queue was stopped. This was not correctly implemented as we
were not checking the right queue. Furthermore, we were dropping frames
that had arrived to their destination if that queue was stopped.Signed-off-by: Thomas Pedersen

mac80211 calls ieee80211_set_wmm_default (which in turn
calls drv_conf_tx()) for every new interface, including
"internal" ones (e.g. monitor interface, which the low-level
driver doesn't know about).Limit this call only to valid interfaces.

The flaglock in struct sta_info has long been
something that I wanted to get rid of, this
finally does the conversion to atomic bitops.The conversion itself is straight-forward in
most places, a few things needed to change a
bit since we can no longer use multiple bits
at the same time.On x86-64, this is a fairly significant code
size reduction:

When an AP interface is removed without the
AP/VLAN interfaces having been removed before
already, the AP-VLAN interface might still
have sleeping stations and buffer multicast
frames which will happen on the AP interface.
Thus, we need to remove AP/VLAN interfaces
before purging buffered broadcast frames.Signed-off-by: Johannes Berg

After the last patch, We are left in a state in which only drivers calling
ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
hardware call ether_setup for their net_devices and don't hold any state in
their skbs. There are a handful of drivers that violate this assumption of
course, and need to be fixed up. This patch identifies those drivers, and marks
them as not being able to support the safe transmission of skbs by clearning the
IFF_TX_SKB_SHARING flag in priv_flagsSigned-off-by: Neil Horman

This adds sparse RCU annotations to most of
mac80211, only the mesh code remains to be
done.Due the the previous patches, the annotations
are pretty simple. The only thing that this
actually changes is removing the RCU usage of
key->sta in debugfs since this pointer isn't
actually an RCU-managed pointer (it only has
a single assignment done before the key even
goes live). As that is otherwise harmless, I
decided to make it part of this patch.Signed-off-by: Johannes Berg

From: Eric W. Biederman
In the beginning with batching unreg_list was a list that was used only
once in the lifetime of a network device (I think). Now we have calls
using the unreg_list that can happen multiple times in the life of a
network device like dev_deactivate and dev_close that are also using the
unreg_list. In addition in unregister_netdevice_queue we also do a
list_move because for devices like veth pairs it is possible that
unregister_netdevice_queue will be called multiple times.So I think the change below to fix dev_deactivate which Eric D. missed
will fix this problem. Now to go test that.Signed-off-by: David S. Miller

iwlwifi and other drivers like to blink their LED
based on throughput. Implement this generically in
mac80211, based on a throughput table the driver
specifies. That way, drivers can set the blink
frequencies depending on their desired behaviour
and max throughput.All the drivers need to do is provide an LED class
device, best with blink hardware offload.Signed-off-by: Johannes Berg

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.Signed-off-by: Javier Cardona

For client STA interfaces, ieee80211_do_stop unsets the relevant
interface's SDATA_STATE_RUNNING state bit prior to cancelling an
interrupted scan. When ieee80211_offchannel_return is invoked as
part of cancelling the scan, it doesn't bother unsetting the
SDATA_STATE_OFFCHANNEL bit because it sees that the interface is
down. Normally this doesn't matter because when the client STA
interface is brought back up, it will probably issue a scan. But
in some cases (e.g., the user changes the interface type while it
is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This
prevents the interface queues from being started. So we
cancel the scan before unsetting the SDATA_STATE_RUNNING bit.Signed-off-by: Brian Cavagnolo

When roaming while we have active BA session,
we can end up transmitting delBA frames to

channel, which can cause warnings.Simply avoid sending those frames, but still
tear down the internal session state, since
they are not really necessary anyway as we
will implicitly disassociate when sending the

When a driver advertises p2p device support,
mac80211 will handle it, but internally it will
rewrite the interface type to STA/AP rather than
P2P-STA/GO since otherwise a lot of paths need

p2p boolean tells drivers whether or not a given
interface will be used for p2p or not.Signed-off-by: Johannes Berg
