This allows users of wpa_supplicant control interface to figure out when
their specific scan command has been started and completed. For example:
CTRL-EVENT-SCAN-STARTED
> scan freq=2412,2417 passive=1 use_id=1
3
CTRL-EVENT-SCAN-RESULTS
CTRL-EVENT-SCAN-STARTED id=3
CTRL-EVENT-SCAN-RESULTS id=3

This allows external programs to request wpa_supplicant to execute
a passive scan (i.e., do not send any Probe Request frames).

This parameter was not really used for anything else apart from a debug
message in the same function that set it. In addition, cfg80211 returns
the set of scanned frequencies even for the full scan, so the code that
was setting this conditionally on frequency list not being there was not
really ever entered either.
Signed-hostap: Jouni Malinen <j@w1.fi>
The new freq=<frequency ranges> parameter to the SCAN command can be
used to request a scan to be performed on the specified set of channels
instead of on all channels. For example, "wpa_cli scan
freq=2400-2500,5180" would scan channels 1-14 and 36. Only the channels
that the driver indicates as enabled and that are within the specified
ranges are included in the request.

In wpa_supplicant_terminate_proc(), while iterating and
terminating interfaces, after an interface is terminated,
we can no longer access its memory as it is no longer valid
and causes a crash.
Fix this by saving the pointer to the next interface before freeing
the current one to avoid accessing an invalid memory location.

This just serves to check if there was a scan within

This is only used for a debug message, but that message prints

The reinit detection skips reinit when the time since the own

The EAPOL RX workaround checks that the events are less than 100 ms

The bgscan simple and learn algorithms should run regardless

The BSS table, scan timeout, and related functionality should use
monotonic time since they care about relative values (age) only.
Unfortunately, these are all connected, so the patch can't be split
further. Another problem with this is that it changes the driver wrapper
API. Though, it seems only the test driver is using this.

The SA query timeout is just a regular timeout (currently

bgscan_learn_get_probe_freq() starts from returning the second entry in
the supp_freqs arrays. Change its logic a bit to make it start from the
first entry.
Signed-hostap: Eliad Peller <eliad@wizery.com>
In case the initial signal level of the associated BSS was above the
given threshold, bgscan_learn module would begin using the
short_interval but never switch to the long_interval as there would be
no signal change event. Make the init code poll for the current signal
level and set scan_interval accordingly. This logic exists in
bgscan_simple but was missing in bgscan_learn.

An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).
If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.
This patch fixes this issue by restoring the previous scan_req value.

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

The shorter 250 ms wait for the next scan request can be used also for
