| * cfg80211: make regulatory_hint() remove REGULATORY_CUSTOM_REGLuis R. Rodriguez2014-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The REGULATORY_CUSTOM_REG can be used during early init with the goal of overriding the wiphy's default regulatory settings in case the alpha2 of the device is not known. In the case that the alpha2 becomes known lets avoid having drivers having to clear the REGULATORY_CUSTOM_REG flag by doing it for them when regulatory_hint() is used.

| | * cfg80211: fix wext-compat for getting retry valueUjjal Roy2014-01-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While getting the retry limit, wext-compat returns the value without updating the flag for retry->flags is 0. Also in this case, it updates long retry flag when short and long retry value are unequal. So, iwconfig never showing "Retry short limit" and showing "Retry long limit" when both values are unequal. Updated the flags and corrected the condition properly. Signed-off-by: Ujjal Roy <royujjal@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* | cfg80211: Add support for QoS mappingKyeyoon Park2013-12-198-1/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to nl80211 API breakage, 5/10 MHz support is broken for all drivers. Fixing it requires adding new API, but that can't be done as a bugfix commit since that would require either updating all APIs in the trees needing the bugfix or cause different kernels to have incompatible API. Therefore, just disable 5/10 MHz support for all drivers. Cc: stable@vger.kernel.org [3.12] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

If a new scan will be requested at this stage, the scan_done_wk will try freeing it (instead of the previous scan), and this will later result in a use after free.

This also adds the previously missing sdata_lock protection in csa_finalize_work.
