f2ca3ea484 mac80211: MFP - Drop unprotected Action frames prior key setup
When management frame protection (IEEE 802.11w) is used, unprotected
Robust Action frames are not allowed prior to key configuration.
However, unprotected Deauthentication and Disassociation frames are
allowed at that point, but not after key configuration.

Make ieee80211_drop_unencrypted() handle the special cases for MFP by
separating the basic Data frame case from Management frame processing
and handle the Management frames only if MFP has been negotiated. In
addition, do not use sdata->drop_unencrypted for Management frames
since the decision on whether to accept the frame depends on the key
being configured.

0c7c10c7cc mac80211: Drop unencrypted frames based on key setup
When using nl80211, we do not have a mechanism to set
sdata->drop_unencrypted. Currently, this breaks code that is supposed
to drop unencrypted frames when protection is expected since
ieee80211_rx_h_decrypt() is optimized to not set rx->key when the
frame is not protected.

This patch modifies ieee80211_rx_h_decrypt() to set rx->key for all
frames and only skip decryption if the frame is not protected. This
allows ieee80211_drop_unencrypted() to correctly drop frames even if
drop_unencrypted is not set.

The changes here are not enough to handle all cases, though. Additional
patches will be needed to implement proper IEEE 802.1X PAE for station
mode (currently, this is only used for AP mode) and some additional
rules are needed for MFP to drop unprotected Robust Action frames prior
to having PTK and IGTK configured.

In theory, the unprotected frames could and should be dropped in
ieee80211_rx_h_decrypt(). However, due to the special case with EAPOL
frames that have to be allowed to be received unprotected even when
keys are set, it is simpler to only set rx->key and allow the
ieee80211_frame_allowed() function to handle the actual dropping of
data frames after 802.11->802.3 header conversion. In addition,
unprotected robust management frames are dropped before they are
processed.

aec6795210 mac80211: Comment the order of HT RX reorder handler vs. RX handlers
We are currently processing block ack reordering as a separate task
before all other RX handlers. In theory, this is wrong since this step
should be done only after duplicate removal (see Figure 6-1 in IEEE
802.11n). However, moving this needs some work and the current
situation is not too bad. Add a comment here so that this small detail
does not get forgotten and who knows, maybe someone has some extra
time to take a look at cleaning this up.

4d050f1dae mac80211: Add a timeout for frames in the RX reorder buffer
This patch allows skbs to be released from the RX reorder buffer in
case they have been there for an unexpectedly long time without us
having received the missing frames before them. Previously, these
frames were only released when the reorder window moved and that could
take very long time unless new frames were received constantly (e.g.,
TCP connections could be killed more or less indefinitely).

This situation should not happen very frequently, but it looks like
there are some scenarious that trigger it for some reason. As such,
this should be considered mostly a workaround to speed up recovery
from unexpected siutation that could result in connections hanging for
long periods of time.

The changes here will only check for timeout situation when adding new
RX frames to the reorder buffer. It does not handle all possible
cases, but seems to help for most cases that could result from common
network usage (e.g., TCP retrying at least couple of times). For more
completely coverage, a timer could be used to periodically check
whether there are any frames remaining in the reorder buffer if no new
frames are received.

a3b8b0569f nl80211: Add Michael MIC failure event
Define a new nl80211 event, NL80211_CMD_MICHAEL_MIC_FAILURE, to be
used to notify user space about locally detected Michael MIC failures.
This matches with the MLME-MICHAELMICFAILURE.indication() primitive.

Since we do not actually have TSC in the skb anymore when
mac80211_ev_michael_mic_failure() is called, that function is changed
to take in the TSC as an optional parameter instead of as a
requirement to include the TSC after the hdr field (which we did not
really follow). For now, TSC is not included in the events from
mac80211, but it could be added at some point.

b3631286ac mac80211: Fix bug in getting rx status for frames pending in reorder buffer
Currently rx status for frames which are completed from reorder buffer
is taken from it's cb area which is not always right, cb is not holding
the rx status when driver uses mac80211's non-irq rx handler to pass it's
received frames. This results in dropping almost all frames from reorder
buffer when security is enabled by doing double decryption (first in hw,
second in sw because of wrong rx status). This patch copies rx status into
cb area before the frame is put into reorder buffer. After this patch,
there is a significant improvement in throughput with ath9k + WPA2(AES).

3cf335d527 mac80211: decrease execution of the associated timer
Currently the timer is triggering every two seconds
(IEEE80211_MONITORING_INTERVAL). Decrease the timer to only trigger during
data idle periods to avoid waking up CPU unnecessary. The timer will
still trigger during idle periods, that needs to be fixed later.

There's also a functional change that probe requests are sent only when the
data path is idle, earlier they were sent also while there was activity
on the data path.

This is also preparation for the beacon filtering support. Thanks to
Johannes Berg for the idea.

469002983f mac80211: split IBSS/managed code
This patch splits out the ibss code and data from managed (station) mode.
The reason to do this is to better separate the state machines, and have
the code be contained better so it gets easier to determine what exactly
a given change will affect, that in turn makes it easier to understand.

This is quite some churn, especially because I split sdata->u.sta into
sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that
way. I've also shuffled around some code -- null function sending is only
applicable to managed interfaces so put that into that file, some other
functions are needed from various places so put them into util, and also
rearranged the prototypes in ieee80211_i.h accordingly.

572e001221 mac80211: use ps-poll when dynamic power save mode is disabled
When a directed tim bit is set, mac80211 currently disables power save
ands sends a null frame to the AP. But if dynamic power save is
disabled, mac80211 will not enable power save ever gain. Fix this by
adding ps-poll functionality to mac80211. When a directed tim bit is
set, mac80211 sends a ps-poll frame to the AP and checks for the more
data bit in the returned data frames.

Using ps-poll is slower than waking up with null frame, but it's saves more
power in cases where the traffic is low. Userspace can control if either
ps-poll or null wakeup method is used by enabling and disabling dynamic
power save.

2ff6a6d4e9 mac80211: fix mesh action frame handling
When I split off the action frame handling I made the code drop
all action frames we don't want to handle. This is wrong since
some action frames are actually handled via rx_h_mgmt through
being queued to the sta/mesh implementations.

Thanks to Li YanBo for noticing the problem.

79617deeeb mac80211: mesh portal functionality support
Currently the mesh code doesn't support bridging mesh point interfaces
with wired ethernet or AP to construct an MPP or MAP. This patch adds
code to support the "6 address frame format packet" functionality to
mesh point interfaces. Now the mesh network can be used as backhaul
for end to end communication.

133b822638 mac80211: make master iface not wireless
There's no need to register the master netdev with cfg80211,
in fact, this is quite dangerous and lead to having to add
checks for the master interface all over the config handlers.
This patch removes the "ieee80211_ptr" from the master iface
in favour of having a small netdev_priv() associated with
the master interface that stores the ieee80211_local pointer.
Because of this, a lot of code in the configuration handlers
can go away. To make this patch easier to verify I have also
removed a number of wiphy_priv() calls in favour of getting
the sdata first and then the local pointer from that.

17741cdc26 mac80211: share STA information with driver
This patch changes mac80211 to share some more data about
stations with drivers. Should help iwlwifi and ath9k when
 they get around to updating, and might also help with
implementing rate control algorithms without internals.

05c914fe33 mac80211: use nl80211 interface types
There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

ccd7b36286 mac80211: clean up some comments
Some comments refer to 80211.o or similar; also remove
a comment about implementing fragments better, we really
have better things to do.

c2b13452b2 mac80211: clean up scan namespace
Most of the scan functions are called ieee80211_sta_scan_*
or similar, make clean it up so they are all just called
ieee80211_scan_*.

213cd118cb mac80211: make bridge_packets a virtual interface option
The bridge_packets configuration really should be per virtual
interface (theoretically per AP/VLAN, but this is much easier);
there currently is no way to set it yet though. Also invert
the option to "NO_BRIDGE_PACKETS" so the default is to bridge.

While at it, also document the flags properly.

472dbc45dc mac80211: split off mesh handling entirely
This patch splits off mesh handling from the STA/IBSS.
Unfortunately it increases mesh code size a bit, but I
think it makes things clearer. The patch also reduces
per-interface run-time memory usage.

Also clean up a few places where ifdef is not required.
