A list of disallowed frequencies for P2P channel list can now be
configured with P2P_SET disallow_freq. The frequencies (or frequency
pairs) are comma separated. For example:
wpa_cli p2p_set disallow_freq 2462,5000-6000
The allowed P2P channel list is constructed by removing explicitly
disallowed channels from the channel list received from the driver.

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.

alternative from distribution terms and from contribution requirements.
The BSD license alternative that has been used in hostap.git (the one

the software in hostap.git can still be used with GPL projects. In

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.
Signed-hostap: Jouni Malinen <j@w1.fi>
Provision Discovery is used as a notification to the GO in the case we
are about join a running group. In such case, there is not much point in
indicating the provision discovery response events to external programs
especially when the PIN-to-be-displayed was different from the one
returned for the p2p_connect command. Skip this confusing event
completely for join-a-running-group case.

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.
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.
