07e2de3193 wpa_supplicant: Allow OpenSSL cipherlist string to be configured
The new openssl_cipher configuration parameter can be used to select
which TLS cipher suites are enabled for TLS-based EAP methods when
OpenSSL is used as the TLS library. This parameter can be used both as a
global parameter to set the default for all network blocks and as a
network block parameter to override the default for each network
profile.

b7328434f7 OpenSSL: Add a mechanism to configure cipher suites
This extends the TLS wrapper code to allow OpenSSL cipherlist string to
be configured. In addition, the default value is now set to
DEFAULT:!EXP:!LOW to ensure cipher suites with low and export encryption
algoriths (40-64 bit keys) do not get enabled in default configuration
regardless of how OpenSSL build was configured.

01b3bbfc66 test: Remove driver_test.c
The driver_test.c driver wrapper (-Dtest in wpa_supplicant and
driver=test in hostapd) was previously used for testing without real
Wi-Fi hardware. mac80211_hwsim-based tests have practically replaced all
these needs and there has been no improvements or use for driver_test.c
in a long while. Because of this, there has not really been any effort
to maintain this older test tool and no justification to change this
either. Remove the obsoleted test mechanism to clean up the repository.

e41e4f9ee3 Simplify memory allocation/freeing for static analyzers
It looks like the use of sm->wpa == WPA_VERSION_WPA2 in two locations
within the function was a bit too much for clang static analyzer to
understand. Use a separate variable for storing the allocated memory so
that it can be freed unconditionally. The kde variable can point to
either stack memory or temporary allocation, but that is now const
pointer to make the design clearer.

6cbdb0c537 Set WoWLAN triggers only if driver capabilities are known
Previously, wpas_set_wowlan_triggers() could have been called in
uninitialized wpa_driver_capa data if the driver interface did not
support reporting of capabilities. While this would not really happen
with a driver wrapper that implements set_wowlan() and as such, would
not cause any difference in practice, it is better to clean this up to
make the code path easier to understand for static analyzers.

61fc90483f P2P: Handle improper WPS termination on GO during group formation
A P2P Client may be able to connect to the GO even if the WPS
provisioning step has not terminated cleanly (e.g., P2P Client does not
send WSC_Done). Such group formation attempt missed the event
notification about started group on the GO and also did not set the
internal state corresponding to the successful group formation.

This commit addresses the missing part by completing GO side group
formation on a successful first data connection if WPS does not complete
cleanly. Also, this commit reorders the STA authorization indications to
ensure that the group formation success notification is given prior to
the first STA connection to handle such scenarios.

debb2dacac P2P: Report group removal reason PSK_FAILURE in timeout case
It was possible for group formation timeout to be the trigger for

case by replacing the reason code with PSK_FAILURE if the PSK failure
timeout gets registed as part of the disconnection processing in the
formation timeout handler.

number of additional DFS channel having been enabled for passive
