This adds ACS support to hostapd. Currently only survey-based
algorithm is available.
To use ACS you need to enable CONFIG_ACS=y in .config and use
channel=0 (or channel=acs_survey) in hostapd.conf.
For more details see wiki page [1] or comments in src/ap/acs.c.

This adds survey dump support for all frequencies
and for specific desired frequencies. This will later
be used by ACS code for spectrum heuristics.

Interfaces that take one or two seconds to reconfigure the link after we
set IFF_ALLMULTI or after we bring the interface up were dropping the
initial TX EAPOL packet which caused excessive delays in authentication.
This change applies to FreeBSD/DragonFly only.

It is possible that when trying to remove a dynamically added interface,
changing its type to station mode is not possible (since the kernel does
not support so in its interface combinations).
Since P2P interfaces are always dynamically added, avoid changing their
type to station in the deinit_ap() and deinit_p2p_client() nl80211
callbacks, assuming that the interface is about to be removed.

Commit 8e12685c43 replaced call to
nl80211_mgmt_unsubscribe() on the deinit path with a
wpa_driver_nl80211_set_mode() call. This is not enough to unregister the
bss->nl_mgmt read socket in all cases. Fix this by unconditionally
unsubscribing from the nl80211 events after having change mode to
station.

drv->assoc_freq was not updated during the connect command (neither
during the command's invocation nor after getting the event) unlike with
auth/assoc case where assoc_freq is updated. This resulted in
nl80211_get_link_noise() (and any other function for that matter) using
the improper drv->assoc_freq value with drivers that use the connect
API. Fix this by updating drv->assoc_freq on connect command and when
fetching the frequency from the driver.

Stop AP command can be used by the driver as an event to indicate that
AP mode has stopped operation. WLAN driver may have encountered errors
that has forced the driver to report this event or concurrent operations
on virtual interfaces may have forced AP operation to be stopped. When
in P2P GO mode, wpa_supplicant uses this event to remove P2P group to
keep in sync with the driver state.

The nl80211 command for setting the TX index does not distinguish TDLS
vs. AP key and as such, the driver would not know what this set TX key
index operation is doing in the TDLS case. This could result in the TX
key index for AP being changed instead if static WEP is used in the AP
connection. Fix the issue by not setting TX key index when configuring a
TDLS key.

The static WEP keys have to be configured for the new VLAN

This allows wpa_supplicant to associate to an AP that has VHT BSS
membership selector set to indicate VHT support is required for the BSS.
Without the patch it was impossible to connect to, e.g., hostapd-based
AP that has require_vht=1. wpa_supplicant was complaining with:
hardware does not support required rate 63.0 Mbps
Signed-hostap: Michal Kazior <michal.kazior@tieto.com>
Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.
This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same
behavior.

Since the P2P_DEVICE support indication was added to kernel before
everything was working properly, there may be kernel versions in use
with the new mechanism breaking P2P functionality (especially with
mac80211_hwsim). For now, disable P2P_DEVICE support by default and
allow it to be enabled with driver_param=p2p_device=1 in the
configuration file. This default behavior may be changed in the future
once the kernel issues has been resolved in stable releases.

The phy name was determined using /sys/class/net/<ifname> but the P2P

For P2P an interface may be created for the P2P client/group. The
create request is done on the P2P management interface, which may

In order to get a P2P-DEVICE-FOUND event the supplicant needs to
see a peer device during SEARCH and LISTEN phase. The SEARCH
phase does a scan so obtaining the scan results for the P2P Device
interface needs to be supported, i.e., use the wdev_id.

For P2P Device the MAC address is determined upon .init2(). The

To support Android the kernel may have a "p2p0" netdev for a P2P Device
even though this isn't very useful, but Android requires a netdev. To
support this in the supplicant, if the interface mode is P2P_DEVICE,
re-set it to the same instead of STATION mode.
Note that this is only possible with a kernel that creates a
netdev for the P2P Device wdev.

Add wdev_id to i802_bss. wdev_id_set indicates whether this id is
