79420f09e7 cfg80211: add more flexible BSS lookup
Add a more flexible BSS lookup function so that mac80211 or
other drivers can actually use this for getting the BSS to
connect to.

d491af19db cfg80211: allow users to request removing a BSS
This patch introduces cfg80211_unlink_bss, a function to
allow a driver to remove a BSS from the internal list and
make it not show up in scan results any more -- this is
to be used when the driver detects that the BSS is no
longer available.

When cfg80211 users have their own allocated data in the per-BSS

destroyed. Add a free_priv method and fix one place where the BSS

2a51931192 cfg80211/nl80211: scanning (and mac80211 update to use it)
This patch adds basic scan capability to cfg80211/nl80211 and
changes mac80211 to use it. The BSS list that cfg80211 maintains
is made driver-accessible with a private area in each BSS struct,
but mac80211 doesn't yet use it. That's another large project.

f976376de0 cfg80211: Allow for strict regulatory settings
This allows drivers to request strict regulatory settings to
be applied to its devices. This is desirable for devices where
proper calibration and compliance can only be gauranteed for
for the device's programmed regulatory domain. Regulatory
domain settings will be ignored until the device's own
regulatory domain is properly configured. If no regulatory
domain is received only the world regulatory domain will be
applied -- if OLD_REG (default to "US") is not enabled. If
OLD_REG behaviour is not acceptable to drivers they must
update their wiphy with a custom reuglatory prior to wiphy
registration.

9aed3cc124 nl80211: New command for adding extra IE(s) into management frames
A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to
add arbitrary IE data into the end of management frames. The interface
allows extra IEs to be configured for each management frame subtype, but
only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth,
Disassoc) are currently accepted in mac80211 implementation.

This makes it easier to implement IEEE 802.11 extensions like WPS and
FT that add IE(s) into some management frames. In addition, this can
be useful for testing and experimentation purposes.

3e0c3ff36c cfg80211: allow multiple driver regulatory_hints()
We add support for multiple drivers to provide a regulatory_hint()
on a system by adding a wiphy specific regulatory domain cache.
This allows drivers to keep around cache their own regulatory domain
structure queried from CRDA.

We handle conflicts by intersecting multiple regulatory domains,
each driver will stick to its own regulatory domain though unless
a country IE has been received and processed.

If the user already requested a regulatory domain and a driver
requests the same regulatory domain then simply copy to the
driver's regd the same regulatory domain and do not call
CRDA, do not collect $200.

0c7dc45d21 cfg80211: Fix regression with 11d on bands
This fixes a regression on disallowing bands introduced with the new
802.11d support. The issue is that IEEE-802.11 allows APs to send
a subset of what a country regulatory domain defines. This was clarified
in this document:

http://tinyurl.com/11d-clarification

As such it is possible, and this is what is done in practice, that a
single band 2.4 GHz AP will only send 2.4 GHz band regulatory information
through the 802.11 country information element and then the current
intersection with what CRDA provided yields a regulatory domain with
no 5 GHz information -- even though that country may actually allow
5 GHz operation. We correct this by only applying the intersection rules
on a channel if the the intersection yields a regulatory rule on the
same band the channel is on.

3f2355cb91 cfg80211/mac80211: Add 802.11d support
This adds country IE parsing to mac80211 and enables its usage
within the new regulatory infrastructure in cfg80211. We parse
the country IEs only on management beacons for the BSSID you are
associated to and disregard the IEs when the country and environment
(indoor, outdoor, any) matches the already processed country IE.

To avoid following misinformed or outdated APs we build and use
a regulatory domain out of the intersection between what the AP
provides us on the country IE and what CRDA is aware is allowed
on the same country.

A secondary device is allowed to follow only the same country IE
as it make no sense for two devices on a system to be in two
different countries.

In the case the AP is using country IEs for an incorrect country
the user may help compliance further by setting the regulatory
domain before or after the IE is parsed and in that case another
intersection will be performed.

CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
present.

5203cdb6ad cfg80211: remove switch from __regulatory_hint()
We have complete control over REGDOM_SET_BY_* enum passed
down to __regulatory_hint() as such there is no need to
account for unexpected REGDOM_SET_BY_*'s, lets just remove
the switch statement as this code does not change and
won't change even when we add 802.11d support.

This patch has no functional changes.
