When using the p2p_oper_reg_class configuration option instead of
p2p_group_add freq parameter, the operating class 124 was not
processed correctly. Include that class in the list of 5 GHz classes
for the p2p_oper_reg_class to resolve this.
Both the SA and IEs from the received Probe Request frames must be
included and the Probe Request RX callback functions may assume that
these are not NULL.
When comparing BSS table entries, handle empty concatenated
vendor-specific IE differently from completely missing IE. This
does not change anything for the only currently compared IE that
can be fragmented (WPS IE), but it is better to have the generic
code here ready for any possible new IE that could be used in
with zero-length data.
Better make sure the address value included in the event message gets
cleared in case the GO Device Address is not known for some reason.
Previously, this could potentially have been some random data from
stack should we ever hit the case where wpa_s->current_ssid is not
set (which should not really happen in normal use cases).
It is now possible to configure the the time in seconds that
wpa_supplicant waits before requesting a new scan after failing to find
a suitable network in scan results.

If WPA/WPA2 was enabled in the configuration, the non-WPA exception
could allow an incorrect AP to be selected from scan results. Do
not use the exception if WPA/WPA2 is enabled in configuration.
Commit c76e5d7f9b moved the
ap_configured_cb() call into a completion callback from AP mode code.
However, this callback can be called before hostap_setup_interface()
returns. In that case, the ap_configured_cb() ended up getting
called before the wpa_supplicant connection information was updated.
Fix this by reordering code to set up everything before calling
hostapd_setup_interface().
This should fix EAPOL reauthentication and rekeying timeout issues
with Intel clients when using WMM (e.g., with IEEE 802.11n). These
stations do not seem to be able to handle EAPOL data frames as
non-QoS Data frames after the initial setup.
This adds STA flags to hapd_send_eapol() driver op to allow
driver_nl80211.c to mark the EAPOL frames as QoS Data frame
when injecting it through the monitor interface.
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.

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.

It is not guaranteed that we will get a CQM signal shortly after setting
up monitoring. In order to establish the correct initial background
scanning rate, poll directly for the signal strength.

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
out-of-band with CQM events.

Change the old design of running a single long living RSN IBSS
instance to keep a separate instance for each IBSS connection.
This fixes number of issues in getting keys set properly for
new connections and is in general quite a bit more correct
design.
Replace compile-time BSS cache expiration age and scan count by config
parameters that can be set via wpa_cli and the new D-Bus API. The latter
is done with interface properties BSSExpireAge and BSSExpireCount.
Move the code snippet to switch on bgscan over to wpa_supplicant.c
from event.c, so that it can be activated on wpa_supplicant_set_state().
Also create a centralized place to switch off bgscan. bgscan is now
turned on in COMPLETED, not ASSOCIATED.
This adds a new command to the interface to remove all configured
netblocks. Without this it's necessary to query properties on the
interface and explicitly remove each netblock.
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">.
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).
This provides feature parity with the old-style D-Bus API. Explicit
properties to control global parameters is preferred but until that
happens this allows doing things like setting pkcs11_engine_path and
pkcs11_module_path via D-Bus.
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.

When wpa_s scans in AP mode, it doesn't propagate the scan event to the
AP code, so that code can get stuck if it uses the callbacks there.
Simply call them where appropriate.
