[WIRELESS] cfg80211: New wireless config infrastructure. This patch creates the core cfg80211 code along with some sysfs bits. This is a stripped down version to allow mac80211 to function, but doesn't include any configuration yet except for creating and removing virtual interfaces. This patch includes the nl80211 header file but it only contains the interface types which the cfg80211 interface for creating virtual interfaces relies on.

cfg80211: add rfkill support To be easier on drivers and users, have cfg80211 register an rfkill structure that drivers can access. When soft-killed, simply take down all interfaces; when hard-killed the driver needs to notify us and we will take down the interfaces after the fact. While rfkilled, interfaces cannot be set UP.

cfg80211: introduce nl80211 testmode command This introduces a new NL80211_CMD_TESTMODE for testing and calibration use with nl80211. There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

help
The nl80211 testmode command helps implementing things like
factory calibration or validation tools for wireless chips.
Select this option ONLY for kernels that are specifically
built for such purposes.
Debugging tools that are supposed to end up in the hands of
users should better be implemented with debugfs.

cfg80211: make spurious warnings less likely, configurable Bob reported that he got warnings in IBSS mode about the ssid_len being zero on a joined event, but only when kmemcheck was enabled. This appears to be due to a race condition between drivers and userspace, when the driver reports joined but the user in the meantime decided to leave the IBSS again, the warning would trigger. This was made more likely by kmemcheck delaying the code that does the check and sends the event. So first, make the warning trigger closer to the driver, which means it's not locked, but since only the warning depends on it that's ok. And secondly, users will not want to have spurious warnings at all, so make those that are known to be racy in such a way configurable.

bool "enable developer warnings"
depends on CFG80211

help
This option enables some additional warnings that help
cfg80211 developers and driver developers, but that can
trigger due to races with userspace.
For example, when a driver reports that it was disconnected
from the AP, but the user disconnects manually at the same
time, the warning might trigger spuriously due to races.

on it (or mac80211).
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. Signed-off-by: Luis R.

cfg80211: Add new wireless regulatory infrastructure 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.
