This restores some of the pre-radio work behavior for scanning by
retrying scan trigger if the driver rejects it (most likely returning
EBUSY in case of nl80211-drivers). Retry is indicated in the
CTRL-EVENT-SCAN-FAILED event with "retry=1".
For manual scans (e.g., triggered through "SCAN" control interface
command), no additional retries are performed. In other words, if upper
layers want to retry, they can do so based on the CTRL-EVENT-SCAN-FAILED
event.

For CONFIG_TESTING_OPTIONS=y builds, add a new test parameter than can
be used to trigger various error cases within wpa_supplicant operations
to make it easier to test error path processing. "SET test_failure
<val>" is used to set which operation fails. For now, 0 = no failures
and 1 = scan trigger fails with EBUSY. More operations can be added in
the future to extend coverage.

Commit ce7b56afab ('WPS: Fix an
interoperability issue with mixed mode and AP Settings') added code to
filter M7 Authentication/Encryption Type attributes into a single bit
value in mixed mode (WPA+WPA2) cases to work around issues with Windows
7. This workaround was lost in commit
d7a15d5953 ('WPS: Indicate current AP
settings in M7 in unconfigurated state') that fixed unconfigured state
values in AP Settings, but did not take into account the earlier
workaround for mixed mode.
Re-introduce filtering of Authentication/Encryption Type attributes for
M7 based on the current AP configuration. In other words, merge those
two earlier commits together to include both the earlier workaround the
newer fix.

Current mesh code uses ap_max_inactivity as inactivity timer. This patch
makes it configurable.
There is another mesh inactivity timer in mac80211. The timer works even
if user_mpm=1. So this patch sets the max value to the timer for
workaround.

There were couple of common cases where the control interface for the
dynamic wpa_supplicant instance could have been left in attached state
until Python ends up cleaning up the instance. This could result in
issues if many monitor interface events were queued for that attached
socket. Make this less likely to cause issues by explicitly detaching
and closing control interfaces before moving to the next test case.

It is easier to debug issues related to the wpa_supplicant control
interfaces being left behind in attached state when the debug log file

It was possible for the Action frame used for entring WNM Sleep Mode to
get dropped on the AP side due to it arriving prior to having processed
EAPOL-Key message 4/4 due to a race condition between Data and
Management frame processing paths. Avoid this by waiting for
AP-STA-CONNECTED event from hostapd prior to trying to enter WNM Sleep
Mode. In addition, make the check for the STA flag change more robust by
allowing the wait to be a bit longer with a loop that terminates as soon
as the flag has changed.

When the STA is forced to disconnect immediately after completion of
4-way handshake, there is a race condition on the AP side between the
reception of EAPOL-Key msg 4/4 and the following Deauthentication frame.
It is possible for the deauthentication notification to be processed
first since that message uses different path from kernel to user space.
If hostapd does not receive EAPOL-Key msg 4/4 prior to deauthentication,
no PMKSA cache entry is added. This race condition was making the test
cases expecting PMKSA caching to work to fail every now and then. Avoid
this issue by waiting for AP-STA-CONNECTED event from hostapd. This
makes sure the PMKSA cache entry gets added on the AP side.

This test case uses get_bss() with a BSSID to find a BSS entry. That can
result in failures if there are multiple BSS entries in wpa_supplicant
BSS table for the same BSSID, e.g., due to an earlier hidden SSID test
case. Explicitly clear the cfg80211 and wpa_supplicant scan caches at
the beginning of this test case to make it less likely for earlier test
cases to trigger a failure here.

Commit 17b8995cf5 ('Interworking: Try to
use same BSS entry for storing GAS results') added a mechanism to try to
pair GAS request and response to a single BSS entry to cover cases where
multiple BSS entries may exists for the same BSSID. However, that commit
did not cover the Hotspot 2.0 ANQP elements. Extend this mechanism to
all ANQP elements. This can help in cases where information in the
Hotspot 2.0 specific ANQP elements got lost if a hidden SSID or some
other reason of duplicated BSS entries was present while doing ANQP
fetches.

This is a regression test case to detect a failure that resulted in an
up to five second busy loop through wpa_supplicant_fast_associate() when

It was possible for interworking_find_network_match() to find a possible
BSS match in a case where more thorough checks in
wpa_supplicant_select_bss() reject network. This itself is fine, in
general, but when combined with wpa_supplicant_fast_associate()
optimization and auto_interworking=1, this resulted in a busy loop of up
to five seconds and a possible stack overflow due to recursion in that
loop.
Fix this by limiting the Interworking wpa_supplicant_fast_associate()
call to be used only once per scan iteration, so that new scan
operations can be completed before going through the scan results again.

Reduce maximum stack use by starting next ANQP fetch operation from an
eloop callback rather than calling interworking_next_anqp_fetch()
directly from interworking_start_fetch_anqp(). This avoids issues that
could potentially make the process run out of stack if long loops of
ANQP operations are executed in cases where automatic Interworking
network selection is used and scan results do not have a full match for
