* nl80211: export supported commandsJohannes Berg2009-03-27
| | | | | | | | | | This makes nl80211 export the supported commands (command groups) per wiphy so userspace has an idea what it can do -- this will be required reading for userspace when we introduce auth/assoc /or/ connect for older hardware that cannot separate auth and assoc.

* cfg80211/nl80211: remove usage of CONFIG_NL80211Reinette Chatre2009-03-27
| | | | | | | | | | | | | The scan capability added to cfg80211/nl80211 introduced a dependency on nl80211 by cfg80211. We can thus no longer have just cfg80211 without nl80211. Specifically, cfg80211_scan_done() calls nl80211_send_scan_aborted() or nl80211_send_scan_done(). Now we remove the option for user to select nl80211. It will always be compiled if user selects cfg80211. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * nl80211: Check that function pointer != NULL before using itJouni Malinen2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS handlers did not verify whether a function pointer is NULL (not supported by the driver) before trying to call the function. The former nl80211 command is available for unprivileged users, too, so this can potentially allow normal users to kill networking (or worse..) if mac80211 is built without CONFIG_MAC80211_MESH=y.

* | cfg80211: Add AP beacon regulatory hintsLuis R. Rodriguez2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When devices are world roaming they cannot beacon or do active scan on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although we have a good regulatory API some cards may _always_ world roam, this is also true when a system does not have CRDA present. Devices doing world roaming can still passive scan, if they find a beacon from an AP on one of the world roaming frequencies we make the assumption we can do the same and we also remove the passive scan requirement. This adds support for providing beacon regulatory hints based on scans. This works for devices that do either hardware or software scanning. If a channel has not yet been marked as having had a beacon present on it we queue the beacon hint processing into the workqueue. All wireless devices will benefit from beacon regulatory hints from any wireless device on a system including new devices connected to the system at a later time. Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | We were not protecting last_request there is a small possible race between an 11d hint and another routine which calls reset_regdomains() which can prevent a valid country IE from being processed.

* | cfg80211: propagate -ENOMEM during regulatory_init()Luis R. Rodriguez2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling kobject_uevent_env() can fail mainly due to out of memory conditions. We do not want to continue during such conditions so propagate that as well instead of letting cfg80211 load as if everything is peachy. Additionally lets clarify that when CRDA is not called during cfg80211's initialization _and_ if the error is not an -ENOMEM its because kobject_uevent_env() failed to call CRDA, not because CRDA failed. For those who want to find out why we also let you do so by enabling the kernel config CONFIG_CFG80211_REG_DEBUG -- you'll get an actual stack trace. So for now we'll treat non -ENOMEM kobject_uevent_env() failures as non fatal during cfg80211's initialization. CC: Greg KH <greg@kroah.com> Signed-off-by: Luis R.

During that rare case and time frame (if its even possible) we don't allow user regulatory changes as cfg80211 is working on enabling its first regulatory domain.
