This moves the cfg80211 specific stuff to new cfg80211 debugfs entries. Non-mac80211 will also get these entries now. There were only 4 which we take: rts_threshold fragmentation_threshold short_retry_limit long_retry_limit Signed-off-by: NLuis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: NJohn W.

Move key handling wireless extension ioctls from mac80211 to cfg80211 so that all drivers that implement the cfg80211 operations get wext compatibility. Note that this drops the SIOCGIWENCODE ioctl support for getting IW_ENCODE_RESTRICTED/IW_ENCODE_OPEN. This means that iwconfig will no longer report "Security mode:open" or "Security mode:restricted" for mac80211. However, what we displayed there (the authentication algo used) was actually wrong -- linux/wireless.h states that this setting is meant to differentiate between "Refuse non-encoded packets" and "Accept non-encoded packets". (Combined with "cfg80211: fix a couple of bugs with key ioctls". -- JWL) Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

When we leave an IBSS, we should clear the SSID and not just the BSSID, but since WEXT allows configuring while the interface is down we must not clear it when leaving due to taking the iface down, so some complications are needed.

Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

This adds IBSS API along with (preliminary) wext handlers. The wext handlers can only do IBSS so you need to call them from your own wext handlers if the mode is IBSS. The nl80211 API requires * an SSID * a channel (frequency) for the case that a new IBSS has to be created It optionally supports * a flag to fix the channel * a fixed BSSID The cfg80211 code also takes care to leave the IBSS before the netdev is set down. If wireless extensions are used, it also caches values when the interface is down and instructs the driver to join when the interface is set up.

Instead, allocate extra IE memory if necessary. Normally, this isn't even necessary since there's enough space. This is a better way of correcting the "held BSS can disappear" issue, but also a lot more code. It is also necessary for proper auth/assoc BSS handling in the future.

Luis reports that there's a circular locking dependency; this is because cfg80211_dev_rename() will acquire the cfg80211_mutex while the device mutex is held, while this normally is done the other way around. The solution is to open-code the device-getting in nl80211_set_wiphy and require holding the mutex around cfg80211_dev_rename rather than acquiring it within. Also fix a bug -- rtnl locking is expected by drivers so we need to provide it. Reported-by: NLuis R.

"cfg80211: add assert_cfg80211_lock() to ensure proper protection" added assert_cfg80211_lock() calls into various places. At least one of them, nl80211_send_wiphy(), should not have been there. That triggers the BUG_ON in assert_cfg80211_lock() and pretty much kills the kernel whenever someone runs hostapd.. Remove that call and make assert_cfg80211_lock() use WARN_ON instead of BUG_ON to be a bit more friendly to users.

Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate. On resume, every BSS in the scan list looks like it was scanned within the last 10 seconds, irregardless of how long the machine was actually asleep.

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.

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: NLuis R.

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: NLuis R.

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.

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.
