93827f456a hostapd: Allow external management frame processing or testing
This enables more convenient protocol testing of station side
functionality in various error cases and unexpected sequences without
having to implement each test scenario within hostapd.
ext_mgmt_frame_handle parameter can be set to 1 to move all management
frame processing into an external program through control interface
events (MGMT-RX and MGMT-TX-STATUS) and command (MGMT_TX).

795baf773f hostapd: Filter channel list updated events after country code change
We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

6023a7880b Restore hapd->interface_added tracking to core hostapd
This reverts parts of commit 390e489c0d
that tried to enable removal of the first BSS. Since that operation is
now forced to remove all BSSs, these changes are not needed. The
hostapd_if_remove() operation in hostapd_free_hapd_data() is problematic
for the first BSS since it ends up freeing driver wrapper information
that is needed later when deinitializing the driver wrapper.

f0793bf191 hostapd: Wait for channel list update after country code change
If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.

5afaa067d9 hostapd: Allow per-BSS (vif) configuration files
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.

4345fe963e bridge: Track inter-BSS usage
Currently, struct hostapd_vlan is a per-BSS data structure which
also contains informations about whether to remove the bridge
or clear wlan / tagged-vlan interface from the bridge.

In a multi-interface multi-BSS setup, this can lead to the following
race condition:
 1. wlan0 creates VLAN A, sets DVLAN_CLEAN_BR and DVLAN_CLEAN_VLAN_PORT
 2. wlan1 creates VLAN A, does not set DVLAN_CLEAN_BR and
    DVLAN_CLEAN_VLAN_PORT as already there
 3. wlan0 removes VLAN A, removes tagged-interface from the bridge
    but not the bridge.
    Now wlan1 VLAN A is unusable due to the missing uplink.
 4. wlan1 removes VLAN A, does not cleanup

Solution:
This requires an inter-BSS inter-interface data structure to track the
bridge / bridge port usage within hostapd. This data structure could
also be used to track any other device-has-been-created-by-hostapd
information or when regarding interface freeing.

2d9ffe1e85 P2P: Fix Action frame processing if Interworking is enabled
GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.
