      cfg80211/mac80211: Add 802.11d support · 3f2355cb
      Luis R. Rodriguez authored
      
      
      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      To avoid following misinformed or outdated APs we build and use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.

      cfg80211: Add new wireless regulatory infrastructure · b2e1b302
      Luis R. Rodriguez authored
      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.

      cfg80211 API for channels/bitrates, mac80211 and driver conversion · 8318d78a
      Johannes Berg authored
      
      
      This patch creates new cfg80211 wiphy API for channel and bitrate
      registration and converts mac80211 and drivers to the new API. The
      old mac80211 API is completely ripped out. All drivers (except ath5k)
      are updated to the new API, in many cases I expect that optimisations
      can be done.
      
      Along with the regulatory code I've also ripped out the
      IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
      unnecessary if the hardware simply gives us whatever channels it wants
      to support and we then enable/disable them as required, which is pretty
      much required for travelling.
      
      Additionally, the patch adds proper "basic" rate handling for STA
      mode interface, AP mode interface will have to have new API added
      to allow userspace to set the basic rate set, currently it'll be
      empty... However, the basic rate handling will need to be moved to
      the BSS conf stuff.
      
      I do expect there to be bugs in this, especially wrt. transmit
      power handling where I'm basically clueless about how it should work.
