* cfg80211: Add kdoc for struct regulatory_requestLuis R. Rodriguez2008-11-101-3/+19
| | | | | | | | | | As regulatory_request gets bigger there will be more questions of what things means, so clarify documenation for it and keep track of the special alpha2 codes we use internally and on the userspace regulatory agents.

* cfg80211: Add regulatory domain intersection capabilityLuis R. Rodriguez2008-11-101-8/+158
| | | | | | | | | | | | | | | | | | | There are certain scenerios where we require intersecting two regulatory domains. This adds intersection support. When we enable 802.11d support we will use this to intersect the regulatory domain from the AP's country IE and what our regulatory agent believes is correct for a country. This patch enables intersection for now in the case where the last regdomain was set by a country IE which was parsed and the user then wants to set the regulatory domain. Since we don't support country IE parsing yet this code path will not be hit, however this allows us to pave the way for 11d support. Intersection code has been tested in userspace with CRDA.

* wireless regulatory: move ignore_requestJohannes Berg2008-11-011-63/+63

* wireless: clean up regulatory ignore_request functionJohannes Berg2008-11-011-40/+27
| | | | | | | | | | | | | | | | | | | | | This function has a few WARNs that may eventually trigger when an AP sends rogue beacons, those must be removed. Some of the comments in the function are also inappropriate as this function is concerned with the global hint, not a per- wiphy thing (which a multidomain flag on a wiphy would imply). I'm convinced that we don't need to do anything to implement multi-domain capability as 802.11-2007 specifies it because it makes only two things mandatory: * starting of BSS/IBSS must have country information (this can easily be done with a mac80211 patch) * a STA must adopt the country information (we already have the framework for this) But we don't have anything implemented anyway for now.

* wireless: remove struct regdom hintingJohannes Berg2008-11-011-47/+16
| | | | | | | | | | | | | The code needs to be split out and cleaned up, so as a first step remove the capability, to add it back in a subsequent patch as a separate function. Also remove the publically facing return value of the function and the wiphy argument. A number of internal functions go from being generic helpers to just being used for alpha2 setting.

* wireless: remove cfg80211_reg_mutexJohannes Berg2008-11-011-3/+0
| | | | | | | | | | | 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. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: clean up static regdomain messJohannes Berg2008-09-241-53/+20
| | | | | | | | | The statically defined regdomains are used in a very convoluted way, use them instead to prime the information we have and then continue operating normally. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: fix regulatory code constJohannes Berg2008-09-241-30/+28
| | | | | | | | | | A few pointers and structures in the regulatory code are const, but because it wasn't done properly a whole bunch of bogus casts were needed to compile without warning.

* cfg80211: Add new wireless regulatory infrastructureLuis R. Rodriguez2008-09-151-113/+692
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Luis R.

* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-0/+153
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.
