Fix merge between commit 3adadc08cc1e ("net ax25: Reorder ax25_exit to
remove races") and commit 0ca7a4c87d27 ("net ax25: Simplify and
cleanup the ax25 sysctl handling")
The former moved around the sysctl register/unregister calls, the
later simply removed them.
With help from Stephen Rothwell.

Legacy rates are not validated while configuring
tx rateset using iw. So below cmd is accepted by nl80211.
sudo iw wlan2 set bitrates legacy-2.4 1 2 3
Validate legacy rates and return
error if any rate in the rateset is not valid.

The background scan completion takes more time when the station is
having heavy uplink traffic. The scan state machine decides to fall
back to home channel on every off-channel visit when there are pending
frames in tx queue. bgscan completion took ~30sec on dual band US
regulatory card.
scan period = (20 active channels * probe timeout) +
(12 passive channels * passive probe timeout) +
(32 * timeout on home channel) +
(32 * flush timeout)

My grand plan to allow drivers to gradually move over
to advertising virtual interface combinations and only
enforce with drivers that do want it enforced doesn't
seem to be working out, only Christian ever added the
advertising (to carl9170), nobody else did.
Begin enforcing combinations in cfg80211 so that users
can rely on the information reported about a device.

The firmware may decide to switch channels while already beaconing, e.g.
in response to a cfg80211 connect request on a different vif. Add this
event to notify userspace when an AP or GO interface has successfully
migrated to a new channel, so it can update its configuration
accordingly.

In WoWLAN, we only get the triggers when we actually get
to suspend. As a consequence, drivers currently don't
know that the device should enable wakeup. However, the
device_set_wakeup_enable() API is intended to be called
when the wakeup is enabled, not later when needed.
Add a new set_wakeup() call to cfg80211 and mac80211 to
allow drivers to properly call device_set_wakeup_enable.

It has happened twice now where elaborate troubleshooting has
undergone on systems where CONFIG_CFG80211_INTERNAL_REGDB [0]
has been set but yet net/wireless/db.txt was not updated.
Despite the documentation on this it seems system integrators could
use some more help with this, so throw out a kernel warning at boot time
when their database is empty.
This does mean that the error-prone system integrator won't likely
realize the issue until they boot the machine but -- it does not seem
to make sense to enable a build bug breaking random build testing.

The nl80211 handling code should ensure as much as
it can that the interface is in a valid state, it
can certainly ensure the interface is running.
Not doing so can cause calls through mac80211 into

Merge batch of fixes from Andrew Morton:
"The simple_open() cleanup was held back while I wanted for laggards to
merge things.
I still need to send a few checkpoint/restore patches. I've been
wobbly about merging them because I'm wobbly about the overall
prospects for success of the project. But after speaking with Pavel
at the LSF conference, it sounds like they're further toward
completion than I feared - apparently davem is at the "has stopped
complaining" stage regarding the net changes. So I need to go back
and re-review those patchs and their (lengthy) discussion."

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire
tree.
Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:
<smpl>

The station_info struct had demanded dBm signal values, but the
cfg80211 wireless extensions implementation was also accepting
"unspecified" (i.e. RSSI) unit values while the nl80211 code was
completely unaware of them. Resolve this by formally allowing the
"unspecified" units while making nl80211 ignore them.

This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT,
to set the inactivity timeout which can be used to remove the
station in AP mode. This can be passed in NL80211_CMD_START_AP
and used by the drivers which have AP MLME in firmware but
don't support get_station() properly. To disable inactivity
timer in userspace, wpa_s for example, there is a new flag,
NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags
through which drivers can register their capability to use
the inactivity timeout to free the stations.

Mesh peer links are established only if average rssi of the peer
candidate satisfies the threshold. This is not in 802.11s specification
but was requested by David Fulgham, an open80211s user. This is a way to avoid
marginal peer links with stations that are barely within range.
This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This
feature is supported only for hardwares that report signal in dBm.

The AP/GO mode API isn't very clearly defined, it
has "set beacon" and "new beacon" etc.
Modify the API to the following:
* start AP -- all settings
* change beacon -- new beacon data
* stop AP -- stop AP mode operation
This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)
Overall, this makes it much clearer what's going
on in the API.

To track authenticated state seems to have been
a design mistake in cfg80211. It is possible to
have out of band authentication (FT), tracking
multiple authentications caused more problems
than it ever helped, and the implementation in
mac80211 is too complex.
Remove all this complexity, and let userspace
do whatever it wants to, mac80211 can deal with
that just fine. Association is still tracked of
course, but authentication no longer is. Local
auth state changes are thus no longer of value,
so ignore them completely.
This will also help implement SAE -- asking the
driver to do an authentication is now almost
equivalent to sending an authentication frame,
with the exception of shared key authentication
which is still handled completely.

calucation of the local maximum transmit power
The local maximum transmit power is the maximum power a wireless device
allowed to transmit. If Power Constraint is presented, the local maximum
power equals to the maximum allowed power defined in regulatory domain
minus power constraint.
The maximum transmit power is maximum power a wireless device capable of
transmitting, and should be used in Power Capability element (7.3.2.16
IEEE802.11 2007).
The transmit power from a wireless device should not greater than the
local maximum transmit power.
The maximum transmit power was not calculated correctly in the current
Linux wireless/mac80211 when Power Constraint is presented.

My patch to validate station flags broke compatibility
with the old station flags setting where all flags are
always set at once since it always set the mask as all
possible flags which ended up being rejected later in
the station add/modify code.
Fix by parsing only the current flags in the old flags
attribute -- new applications and new flags should use
(and will now require) the new flags attribute where
the mask is given by the application.

Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:
o Frans Pop RIP 2010 [0]
- Frans Pop <elendil@planet.nl>
- Frans Pop <fjp@debian.org>
o Nokia RIP February, 11, 2011 [1], [2]
- ext-yuri.ershov@nokia.com
- kalle.valo@nokia.com
Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.
As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.
The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

When we restore regulatory settings the world regulatory domain
is properly reset on cfg80211 (or user prefered regulatory domain)
but we were never setting back channel values for drivers that use
WIPHY_FLAG_CUSTOM_REGULATORY. Set these values up again by using
the orig_ channel parameters.
This fixes restoring custom regulatory settings upon disconnect
events.

By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the
wiphy to adjust itself to the country IE power information if the
card had no regulatory data but we had no way to tell cfg80211 that if
the card also had its own custom regulatory domain (these are typically
custom world regulatory domains) that we want to follow the country IE's
noted values for power for each channel. We add support for this and
document it.
This is not a critical fix but a performance optimization for cards
with custom regulatory domains that associate to an AP with sends
out country IEs with a higher EIRP than the one on the custom
regulatory domain. In practice the only driver affected right now
are the Atheros drivers as they are the only drivers using both
WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY --
used on cards that have an Atheros world regulatory domain. Cards
that have been programmed to follow a country specifically will not
follow the country IE power. So although not a stable fix distributions
should consider cherry picking this.

The nl80211 station handling code is a bit messy
and doesn't do a lot of validation. It seems like
this could be an issue for drivers that don't use
mac80211 to validate everything.
As cfg80211 doesn't keep station state, move the
validation of allowing supported_rates to change
for TDLS only in station mode to mac80211.
