It was possible for wpa_auth_sm_event(WPA_DEAUTH) to be called from
wpa_sm_step() iteration in the case the EAPOL authenticator state
machine ended up requesting the station to be disconnected. This
resulted in unnecessary recursive call to wpa_sm_step(). Avoid this by
using the already running call to process the state change.
It was possible to hit this sequence in the hwsim test case
ap_wpa2_eap_eke_server_oom.

Clearing keyRun here is not specified in IEEE Std 802.1X-2004, but it
looks like this would be logical thing to do here since the EAPOL-Key
exchange is not possible in this state. It is possible to get here on
disconnection event without advancing to the AUTHENTICATING state to
clear keyRun before the IEEE 802.11 RSN authenticator state machine runs
and that may advance from AUTHENTICATION2 to INITPMK if keyRun = TRUE
has been left from the last association. This can be avoided by clearing
keyRun here.
It was possible to hit this corner case in the hwsim test case
ap_wpa2_eap_eke_server_oom in the case getKey operation was forced to
fail memory allocation. The following association resulted in the
station getting disconnected when entering INITPMK without going through
EAP authentication.

This allows an empty nested list (i.e., no MAC addresses) to be included
in the NL80211_CMD_SET_MAC_ACL message unlike with
nla_nest_start()/nla_nest_end() where the current libnl implementation
removes the "empty" attribute and causes cfg80211 to reject the command.

While the EAPOL-Key MIC derivation was already changed from SHA256 to
SHA384 for the Suite B 192-bit AKM, KDF had not been updated similarly.
Fix this by using HMAC-SHA384 instead of HMAC-SHA256 when deriving PTK
from PMK when using the Suite B 192-bit AKM.

Config file is written to a temp file and then it is renamed to the
original config file. However, it is possible that the rename operation
will be commited to storage while file data will be still in cache
causing original config file to be empty or partially written in case of
a system reboot without a clean shutdown. Make this less likely to occur
by forcing the data to be written to the storage device before renaming
the file.

This allows a BSS entry to be expired if the AP has changed its SSID
while maintaining the same BSSID and we are associated with the BSS.
Previously, the same BSSID was enough to mark all BSS entries from the
BSSID as in use regardless of the SSID and as such, they could remain in
the wpa_supplicant BSS table indefinitely as long as the association
remaining.

Commit 7da4f4b499 ('WPS: Check maximum
HTTP body length earlier in the process') added too strict check for
body length allocation. The comparison of new_alloc_nbytes against
h->max_bytes did not take into account that HTTPREAD_BODYBUF_DELTA was
added to previous allocation even if that ended up going beyond
h->max_bytes. This ended up rejecting some valid HTTP operations, e.g.,
when checking AP response to WPS ER setting selected registrar.
Fix this by taking HTTPREAD_BODYBUF_DELTA into account.

This can be used to limit TLS session resumption within a TLS library
implementation to apply only for the cases where the same EAP method is
used. While the EAP server method matching will be enforced separately
by EAP server method implementations, this additional steps can optimize
cases by falling back to full authentication instead of having to reject
attempts after having completed session resumption successfully.

The P2P group is not yet operating when going through GO Negotiation
exchange. Previously, an old cached scan result could be used to skip
the scan immediately after the GO Negotiation. While this is quite
unlikely to happen in practice, we can easily force a scan here now with
the generic scan_min_time mechanism. Do that to avoid any corner cases
that a previous instance of the group could have if found in cached scan
results.

The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.
Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

The -T<ctrl_iface> command line argument can now be used to start
eapol_test in mode where the configuration file is not needed and the

Network profile is also managed through the control interface in this

BoringSSL commit 533ef7304d9b48aad38805f1997031a0a034d7fe ('Remove
SSL_clear calls in handshake functions.') triggered a regression for
EAP-TLS/TTLS/PEAP session resumption in wpa_supplicant due to the
removed SSL_clear() call in ssl3_connect() going away and wpa_supplicant
not calling SSL_clear() after SSL_shutdown(). Fix this by adding the
SSL_clear() call into wpa_supplicant after SSL_shutdown() when preparing
the ssl instance for another connection.
While OpenSSL is still call SSL_clear() in ssl3_connect(), it looks to
be safe to add this call to wpa_supplicant unconditionally.
