Jouni Malinen 9f104b0324 hostapd: Reuse hostapd_clear_old() for RELOAD command
Instead of duplicating the functionality and missing changes (like the
hostapd_broadcast_wep_clear() call), use the hostapd_clear_old()
function that was already used for the similar case with configuration
file reload.

Janusz Dziedzic e76da50529 hostapd: Add AP DFS support
Add DFS structures/events handlers, CAC handling, and radar detection.
By default, after radar is detected or the channel became unavailable, a
random channel will be chosen.

This patches are based on the original work by Boris Presman and
Victor Goldenshtein. Most of the DFS code is moved to a new dfs.c/dfs.h
files.

There is no need to use the bss variable which is used only within a

Jouni Malinen ed1bf011da Allow hostapd config file for dynamically added interface
This extends hostapd global control interface command "ADD" to use a
configuration file instead of requiring configuration to be built using
SET command.

The command format is now following:
ADD <ifname> <control path|config=<path to config>>

For example:

ADD wlan0 /var/run/hostapd
ADD wlan0 config=/tmp/hostapd.conf

When using the configuration file option, ctrl_interface parameter in
the file needs to be set to allow ENABLE command to be issued on the new
interface.

Jouni Malinen 97bacf7cf6 Do not clear hostapd configuration parameters on disable-iface
There was a comment about the the cleanup steps being from
hostapd_cleanup_iface(). However, the operations that cleared some
security parameters do not seem to exist elsewhere and do not make sense
here. Remove them to avoid changing configuration with DISABLE followed
by ENABLE.

Michal Kazior 50f4f2a066 hostapd: Add Automatic Channel Selection (ACS) support
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.

Sujith Manoharan 3f9a8137f5 hostapd: Add a config option to control beaconing
In a AP/STA concurrent setup, if the STA interface is continually
scanning, trying to connect to a network, the AP interface
is basically broken since beaconing would be erratic.

This option can be used in a WDS setup where one AP acts as a
Client/AP-Repeater. The Repeater AP interface has to start beaconing
only after the Client interface has established a WDS link with the
"Root AP".

Use reason code 3 (Deauthenticated because sending STA is leaving)
instead of reason code 2 (Previous authentication ot valid) in the
Deauthentication frame sent at the time a BSS is terminated. This is
more accurate reason for the message and allows the stations to get
better understand on why they were disconnected. This can be useful

P2P group session was ended per P2P specification section 3.2.9.

The AP code might, currently only in the case of HT40, defer actual
