85660d312a Add DATA_TEST_FRAME for testing Data frame processing on AP side
The new hostapd control interface command can be used in automated
testing to verify how AP processes Data frames with arbitrary contents.
This is enabled only in builds with CONFIG_TESTING_OPTIONS=y.

df131d4597 proxyarp: Try multicast-to-unicast conversion only for authorized STAs
There is no point in trying to send the unicast converted version to a
STA that is not in authorized state since the driver would be expected
to drop normal TX Data frames in such state.

67aeee118a tests: Convert proxyarp tests to use DATA_TEST_FRAME
This is more robust and extensible than configuring IPv6 addresses on

9ed53f5edf tests: Increase WPS connection timeout to make tests more robust
It was possible to hit the 10 second timeout in some test cases under

These timeouts are not really indicating any real error, so make them

It was possible for wmm_ac_deinit() not getting called when an interface

wmm_ac_notify_disassoc() did not get called. This resulted in leaking

ac330cfd87 P2P: Reinvite with social operation channel if no common channels
If invitation to reinvoke a persistent group from the GO fails with the
peer indicating that there are no common channels, there is no defined
means for the peer to indicate which channel could have worked. Since
this type of issue with available channels changing over time can
happen, try to work around this by retrying invitation using one of the
social channels as the operating channel unless a specific operating
channel was forced for the group.

7a94120ea9 nl80211: Clear ignore_if_down_event if interface is up
It was possible for the ignore_if_down_event flag to remain set in some
cases where interface mode change required the interface to be set down
temporarily. If that happened, the following rfkill interface down could
have been ignored and device could have been left trying to scan or
connect (which would all fail due to the interface beign down). Clean
this up by clearing the ignore_if_down_event flag on the interface down
event regardless of whether the interface is up at the time this event
is processed.

3a7414b6a6 Do not re-open Android control sockets
On Android, the control socket being used may be the socket that is
created when wpa_supplicant is started as a /init.*.rc service. Such a
socket is maintained as a key-value pair in Android's environment.
Closing this control socket would leave wpa_supplicant in a bad state.
When wpa_supplicant re-opens the ctrl_iface socket, it will query the
Android's environment, and will be returned with the same socket
descriptor that has already been closed.

builds with toolchains that do not support IPv6 even if Hotspot 2.0 is

adf96fb66b WPS: Add explicit message length limit of 50000 bytes
Previously, this was implicitly limited by the 16-bit length field to

Add an explicit (but pretty arbitrary) limit of 50000 bytes to avoid
this. The actual WSC messages are significantly shorter in practice, but
there is no specific protocol limit, so 50000 is as good as any limit to
use here.
