439efd1eac bgscan_simple: Reschedule first fast scan
If the scan interval switches to the short interval soon after a
scan, bgscan_simple should not immediately scan again. However,
it should also make sure that the next scan occurs no later than
the new, short scan interval.

6d21d41125 bgscan_simple: Time out short scan interval
We gain diminishing returns by the short scan interval. The short
scan interval is used to hunt for a better AP if the RSSI of the
current AP drops. However, if we never roam, and the AP continues
to have low RSSI, at some point we should give up and return to
the slow background scan rate, otherwise we waste a lot of power.

1c5c7273f5 driver: Function to directly poll signal quality
This provides a means for the supplicant to directly request signal
quality metrics from the driver. This is useful, for example for
background scan algorithms that might ask desire this information

bc8397822b wpa_supplicant: Search BSS list from back to front
This fixes an issue seen in our wifi testbed, where we frequently
switch the SSID of the AP. wpa_supplicant's BSS list will have, for
example both <bssid, "Check11b"> (from the previous test) and <bssid,
"Check11g"> (from the current test) - note that the bssid is the same for
both. The (old) D-Bus API for fetching scan responses from wpa_supplicant
is fetch-by-bssid, so the caller (flimflam) incorrectly believes we're
associated with <bssid, "Check11b">.

2b65b30da8 dbus: Add D-Bus methods to flush the BSS cache
Add an "Interface.FlushBSS" method to the new D-Bus API and a "flush"
method to the old API. Both take an age parameter that is a threshold
(in seconds) for selecting entries to evict. Setting this parameter
to zero flushes all entries from the cache.

This mechanism is useful for a connection manager to clear state at
startup and on resume (where the age parameter may be used to hold
onto recent/valid data).

c76e5d7f9b wpa_s AP mode: complete only when setup is complete
The AP code might, currently only in the case of HT40, defer actual
enabling to after a scan. In this case, the wpa_s AP code gets confused.
Add a callback for it to use and make it use it to finish only when the
setup has actually completed.

With appropriate hacks in place this allows using HT40 in P2P mode.

  with the old interface)

resulted in blacklisting not working in the expected way (i.e., the same

Use a common function to handle all these cases and fix the blacklist
operation. Use smaller delay before trying to scan again during the

bbb921daaa Maintain internal entropy pool for augmenting random number generation
By default, make hostapd and wpa_supplicant maintain an internal
entropy pool that is fed with following information:

hostapd:
- Probe Request frames (timing, RSSI)
- Association events (timing)
- SNonce from Supplicants

wpa_supplicant:
- Scan results (timing, signal/noise)
- Association events (timing)

The internal pool is used to augment the random numbers generated
with the OS mechanism (os_get_random()). While the internal
implementation is not expected to be very strong due to limited
amount of generic (non-platform specific) information to feed the
pool, this may strengthen key derivation on some devices that are
not configured to provide strong random numbers through
os_get_random() (e.g., /dev/urandom on Linux/BSD).

This new mechanism is not supposed to replace proper OS provided
random number generation mechanism. The OS mechanism needs to be
initialized properly (e.g., hw random number generator,
maintaining entropy pool over reboots, etc.) for any of the
security assumptions to hold.

If the os_get_random() is known to provide strong ramdom data (e.g., on
Linux/BSD, the board in question is known to have reliable source of
random data from /dev/urandom), the internal hostapd random pool can be
disabled. This will save some in binary size and CPU use. However, this
should only be considered for builds that are known to be used on
devices that meet the requirements described above. The internal pool
is disabled by adding CONFIG_NO_RANDOM_POOL=y to the .config file.

ab72eb5256 P2P: Accept invitations to already running persistent group
We can automatically accept invitations that are for a persistent
group that is already running. There is no need to confirm this
separately or preparare a new group interface.

9d39057c2b P2P: Stop p2p_find/p2p_listen when Invitation is accepted
When an Invitation to reinvoke a persistent group is accepted,
we need to make sure that any pending p2p_find or p2p_listen
operation gets stopped to avoid consuming all radio resources
doing device discovery while the group is being set up.

requested group is already running and if so, do not try to
start another copy of it.

ca806fb540 P2P: Indicate WPS events from AP mode only during group formation
The duplicated WPS event in the parent interface should only be used
during P2P group formation, i.e., when the WPS operation was actually
started using the parent interface. When authorizing a client to
connect to an already running group, the WPS command is issued on
the group interface and there is no need to duplicate the event to
the parent interface.

d1b024c9e5 P2P: Make sure wpa_s->global->p2p_group_formation gets cleared
This pointer is now used in number of places to check whether an
interface is in P2P Group Formation, so we better make sure it gets
cleared when group formation has been completed. This was done in
only some of the cases.

9dd7d6b09c WPS: Add special AP Setup Locked mode to allow read only ER
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change then.
In other words, the protocol is allowed to continue past M2, but
is stopped at M7 when AP is in this mode. WPS IE does not
advertise AP Setup Locked in this case to avoid interoperability
issues.

In wpa_supplicant, use ap_setup_locked=2 by default. Since the AP PIN
is disabled by default, this does not enable any new functionality
automatically. To allow the read-only ER to go through the protocol,
wps_ap_pin command needs to be used to enable the AP PIN.

70d84f11fe WPS: Add wps_ap_pin ctrl_iface command for wpa_supplicant AP mode
This can be used to control the AP PIN in wpa_supplicant AP mode
in the same way as the identical command in hostapd ctrl_iface.

bb79dc720b P2P: Fix invitation-to-running-group handling
The pending_invite_ssid_id of -1 (running group, not persistent) was
being stored incorrectly in the group interface, not device interface
(i.e., parent of the group interface) and consequently, the incorrect
information was used when processing the Invitation Response.

If there was a persistent group credentials stored with network id
0, those were used instead to try to set up a persistent group
instead of using the already running group.

5496062919 P2P: Update pending join interface address during scans
Since the P2P peer entry may not have been available at the time the
join request was issued, we need to allow the P2P Interface Address
to be updated during join-scans when the P2P peer entry for the GO
may be added.
