cfg80211/mac80211: Add 802.11d support

2008-11-25T21:41:26+00:00

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To avoid following misinformed or outdated APs we build and use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.

wireless: remove cfg80211_reg_mutex

2008-10-31T23:00:42+00:00

This mutex is wrong, we use cfg80211_drv_mutex (which should
possibly be renamed to just cfg80211_mutex) everywhere except
in one place, fix that and get rid of the extra mutex.

Also get rid of a spurious regulatory_requests list definition.

cfg80211: fix debugfs error handling

2008-10-15T00:48:25+00:00

If something goes wrong creating the debugfs dir or when
debugfs is not compiled in, the current code might lead to
trouble; make it more robust.

wireless: a global static to local static improvement

2008-09-24T20:18:04+00:00

There are two improvements in this simple patch:
1. wiphy_counter is a static var only used in one function, so
   can use local static instead of global static;
2. wiphy_counter wrap handling killed one comparision;

cfg80211: show interface type

2008-09-24T20:18:00+00:00

This patch makes cfg80211 show the interface in the nl80211
information about a specific interface. API users are required
to keep the type updated (everything else is fairly complicated)
but you will get a warning if you fail to keep it updated.

cfg80211: clean up regulatory mess

2008-09-24T20:17:59+00:00

The recent code from Luis is an #ifdef hell and contains lots of
code that's stuffed into the wrong file making a whole bunch of
things needlessly non-static, and besides, what is it doing in
core.c??

cfg80211: fix static regdomains

2008-09-24T20:17:58+00:00

When Luis added the static regdomains back he used +/-20
of the centre frequencies to account for 40MHz bandwidth
neglecting the fact that 40MHz bandwidth cannot be used
on the channels close to the allowed band edges.

cfg80211: Add new wireless regulatory infrastructure

2008-09-15T20:48:19+00:00

This adds the new wireless regulatory infrastructure. The
main motiviation behind this was to centralize regulatory
code as each driver was implementing their own regulatory solution,
and to replace the initial centralized code we have where:

* only 3 regulatory domains are supported: US, JP and EU
* regulatory domains can only be changed through module parameter
* all rules were built statically in the kernel

We now have support for regulatory domains for many countries
and regulatory domains are now queried through a userspace agent
through udev allowing distributions to update regulatory rules
without updating the kernel.

Each driver can regulatory_hint() a regulatory domain
based on either their EEPROM mapped regulatory domain value to a
respective ISO/IEC 3166-1 country code or pass an internally built
regulatory domain. We also add support to let the user set the
regulatory domain through userspace in case of faulty EEPROMs to
further help compliance.

Support for world roaming will be added soon for cards capable of
this.

For more information see:

http://wireless.kernel.org/en/developers/Regulatory/CRDA

For now we leave an option to enable the old module parameter,
ieee80211_regdom, and to build the 3 old regdomains statically
(US, JP and EU). This option is CONFIG_WIRELESS_OLD_REGULATORY.
These old static definitions and the module parameter is being
scheduled for removal for 2.6.29. Note that if you use this
you won't make use of a world regulatory domain as its pointless.
If you leave this option enabled and if CRDA is present and you
use US or JP we will try to ask CRDA to update us a regulatory
domain for us.
