2012-10-23cfg80211: add tracing for P2P Device start/stopJohannes Berg

2012-10-18cfg80211: add support for flushing old scan resultsSam Leffler
Add an NL80211_SCAN_FLAG_FLUSH flag that causes old bss cache entries to be flushed on scan completion. This is useful for collecting guaranteed fresh scan/survey result (e.g. on resume). For normal scan, flushing only happens on successful completion of a scan; i.e. it does not happen if the scan is aborted. For scheduled scan, previous scan results are flushed everytime when we get new scan results. This feature is enabled by default. Drivers can disable it by unsetting the NL80211_FEATURE_SCAN_FLUSH flag.

2012-09-10netlink: Rename pid to portid to avoid confusionEric W. Biederman
It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.

2012-08-20cfg80211: add P2P Device abstractionJohannes Berg
In order to support using a different MAC address for the P2P Device address we must first have a P2P Device abstraction that can be assigned a MAC address. This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel.

2012-07-17cfg80211: add cellular base station regulatory hint supportLuis R. Rodriguez
Cellular base stations can provide hints to cfg80211 about where they think we are. This can be done for example on a cell phone. To enable these hints we simply allow them through as user regulatory hints but we allow userspace to clasify the hint as either coming directly from the user or coming from a cellular base station. This option is only available when you enable CONFIG_CFG80211_CERTIFICATION_ONUS. The base station hints themselves will not be processed by the core unless at least one device on the system supports this feature. Signed-off-by: Luis R.

2012-07-13cfg80211/mac80211: re-add get_channel operationJohannes Berg
This essentially reverts commit 2e165b818456 but introduces the get_channel operation with a new wireless_dev argument so that you can retrieve the channel per interface. This is necessary as even though we can track all interface channels (except monitor) we can't track the channel type used. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The management frame and remain-on-channel APIs will be needed in the P2P device abstraction, so move them over to the new wdev-based APIs. Userspace can still use both the interface index and wdev identifier for them so it's backward compatible, but for the P2P Device wdev it will be able to use the wdev identifier only.

2012-07-09nl80211: add NL80211_FLAG_NEED_WDEVJohannes Berg

2012-07-09nl80211: prepare for non-netdev wireless devsJohannes Berg
In order to support a P2P device abstraction and Bluetooth high-speed AMPs, we need to have a way to identify virtual interfaces that don't have a netdev associated. Do this by adding a NL80211_ATTR_WDEV attribute to identify a wdev which may or may not also be a netdev. To simplify things, use a 64-bit value with the high 32 bits being the wiphy index for this new wdev identifier in the nl80211 API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-07-05{nl,cfg}80211: support high bitratesVladimir Kondratiev
Until now, a u16 value was used to represent bitrate value. With VHT bitrates this becomes too small. Introduce a new 32-bit bitrate attribute. nl80211 will report both the new and the old attribute, unless the bitrate doesn't fit into the old u16 attribute in which case only the new one will be reported. User space tools encouraged to prefer the 32-bit attribute, if available (since it won't be available on older kernels.)

2012-06-27cfg80211: don't allow WoWLAN support without CONFIG_PMJohannes Berg
When CONFIG_PM is disabled, no device can possibly support WoWLAN since it can't go to sleep to start with. Due to this, mac80211 had even rejected the hardware registration. By making all the code and data for WoWLAN depend on CONFIG_PM we can promote this runtime error to a compile-time error. Add #ifdef around all WoWLAN code to remove it in systems that don't need it as they never suspend.

2012-06-20cfg80211: fix regression in multi-vif AP startFelix Fietkau
Commit "cfg80211: provide channel to start_ap function" assumes that the channel is always passed to the NL80211_CMD_START_AP command, however in case of multi-BSSID, hostapd only passes the channel for the first vif. This makes starting beaconing on secondary vifs fail with -EINVAL.
