This allows credentials to be set with a specific priority to allow

a565c23bf3 WPS: Fix regression in post-WPS scan optimization
Commit 3c85f144ce fixed issues with P2P
Action frame TX after disconnection by clearing wpa_s->assoc_freq.
This resulted in a regression to the post-WPS scan optimization that
used wpa_s->assoc_freq to enable fast single-channel scan. Fix this by
copying wpa_s->assoc_freq to a local variable before calling
wpa_supplicant_deauthenticate() that ends up calling
wpa_supplicant_mark_disassoc() which will clear assoc_freq.

the software in hostap.git can still be used with GPL projects. In
addition, any new contribution to hostap.git is expected to be licensed

f63b854215 P2P: Wait for PD-before-join response
Even though the Provision Discovery Response frame from PD-before-join
does not really provide any additional information, it can be better to
wait for it before starting the join operation. This adds a minimal
extra latency in the most common case and cleans up the sequence of
driver operations and debug log by avoiding potential processing of the
Provision Discovery Response while already running a scan for the actual
connection.

If transmission of Provision Discovery Request fails, join operation is
started without the additional wait. In addition, a new timeout is used
to start the join if Provision Discovery Response is lost for any
reason.

87343c2017 bgscan_simple: Refinements to fast-scan backoff
These changes account for situations where the CQM threshold
might be approximately the same as the currently received signal,
and thus CQM events are triggered often due to measurement
error/small fluctuations.  This results in scanning occurring
too frequently.

Firstly, inhibit the immediate scan when the short-scan count
is at the maximum.  This keeps bursts of CQM toggling from
causing a torrent of back-to-back scans.  This does not inhibit
immediate scans if the CQM triggers a second time (if the signal
falls lower past the hysteresis).  This reduces the scan rate in
the worst case (fast-rate toggling high/low CQM events) to the
short scan interval.

Secondly, change the behavior of the short scan count so it acts like
a "leaky bucket".  As we perform short-scans, the bucket fills until
it reaches a maximal short-scan count, at which we back-off and
revert to a long scan interval.  The short scan count decreases by
one (emptying the bucket) every time we complete a long scan interval
without a low-RSSI CQM event.

This reduces the impact of medium-rate toggling of high/low CQM
events, reducing the number of short-interval scans that occur before
returning to a long-interval if the system was recently doing
short scans.

0f4668ceac Try fallback drivers if global init for preferred drivers fails
Driver global init was considered a hard failure. Thus if, for example,
you used the Broadcom STA driver and didn't have nl80211 or cfg80211
loaded into the kernel, and specified a driver value of "nl80211,wext",
the nl80211 driver's global init would fail with the following message:

nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'

but since global init was a hard failure, creating the supplicant
interface would fail and the WEXT driver would not be tried.
Give other drivers a chance instead.

d93dfbd588 Delay scan request on select_network if disconnecting
The disconnection command results in disassociation and deauthentication
events which were previously processed during the scan in case of
select_network command being used while associated with another network.
While this works in most cases, it can result in confusing event

between the disconnection and scan request to allow the disconnection
events to be processed prior to starting the new scan.

cd2f4ddfb9 Update WPA/RSN IE properly for driver based BSS selection
This patch fixes an issue with roaming for drivers that set
WPA_DRIVER_FLAGS_BSS_SELECTION (currently ath6kl). On moving to an AP
with a different BSSID, an EVENT_ASSOC is received and the subsequent
4-way handshake may fail because of a mismatch between the RSN IE in
message 3/4 and in Beacon/Probe Response. This happens only when the APs
use different RSN IE contents and ap_scan is set to 1, since
wpa_supplicant fails to update its cached IEs.

Initial association may fail, too, in case of multiple APs with
the same SSID, since BSSID selection is done by the driver and again
a mismatch could be seen.

Fix these two issues by clearing and updating the cached IEs on
receiving an Association event from the driver. Also, retrieve the
scan results when the new BSS information is not present locally.

3d9975d5b0 Do not trigger fast reconnection on locally generated deauth/disassoc
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.

Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.

It will be very useful for clients to know upon receipt of such a message

Now that the peer information is available and the API is changed
already, the function composing the D-Bus message might as well include
all GO negotiation information. This is done with a dict to make things

We traced it down to a GTK failure, and he then
bisected it to commit bdffdc5ddb:
"AP: Reorder WPA/Beacon initialization".

The reason this commit broke it is that the state
machine's GInit variable is never set to false as
wpa_init_keys() never gets called, and thus new
keys are generated every time the state machine
executes.

Fix this by calling wpa_init_keys() when the new

so we need to work around it in order to keep compatibility

registrar to skip overlap detection if P2P addresses of two

ea5bae4731 Increase min sched_scan interval from 2 to 10 seconds
Trying to run sched_scan round every two seconds by defaults sounds way
too frequent since dualband cards are unlikely to be able to complete
the full scan cycle in two seconds. For now, set the hardcoded value to
10 seconds to make this somewhat more reasonable.

0b7a25c00f Use normal scan before sched_scan if that can speed up connection
When normal scan can speed up operations, use that for the first three
scan runs before starting the sched_scan to allow user space sleep more.
We do this only if the normal scan has functionality that is suitable
for this or if the sched_scan does not have better support for multiple
SSIDs.

Previously, only networks with scan_ssid=1 were included in sched_scan.
This needs to behave similarly to the normal scan where broadcast SSID

ef992bbd3b wpa_gui-qt4: Improve scan results signal display
Display signal strength in dBm with visual indicator in the form of a
bar for scan results displayed by wpa_gui-qt4. Any signal > -35dBm is
treated as full signal bar, signals between range of -95<->-35dBm are
displayed linearly. Convert WEXT signal level value to scale that
nl80211 typically reports in dBm. The condition which differentiates
8-bit WEXT dBm and regular dBm is probably fragile, but there is
currently no way to know what the driver is going to report for signal
strength.

Use the no-ACK send_mlme request to transmit Probe Response frames
in P2P Listen state. This reduces number of unnecessary transmissions
if the peer device has already moved away from the channel. It will most
likely go through Search state multiple times anyway, so even if the
response were to be lost, a new retry will happen at higher layer.
