This adds kek_len argument to aes_wrap() and aes_unwrap() functions and
allows AES to be initialized with 192 and 256 bit KEK in addition to
the previously supported 128 bit KEK.

Update that to use stack_index_t variable to avoid this just like the

BoringSSL is Google's cleanup of OpenSSL and an attempt to unify
Chromium, Android and internal codebases around a single OpenSSL.
As part of moving Android to BoringSSL, the wpa_supplicant maintainers
in Android requested that I upstream the change. I've worked to reduce
the size of the patch a lot but I'm afraid that it still contains a
number of #ifdefs.

If the first entry in the PMKSA cache did not match the station's MAC
address, an infinite loop could be reached in pmksa_cache_get_okc() when
trying to find a PMKSA cache entry for opportunistic key caching cases.
This would only happen if OKC is enabled (okc=1 included in the

Previously, WPA/WPA2 case ended up using the hardcoded
dot11RSNAConfigPMKLifetime (43200 seconds) for PMKSA cache entries
instead of using the Session-Timeout value from the RADIUS server (if
included in Access-Accept). Store a copy of the Session-Timeout value
and use it instead of the default value so that WPA/WPA2 cases get the
proper timeout similarly to non-WPA/WPA2 cases.

Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.
Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.

It was possible for the p2p_go_neg_start timeout handler to get called
when there was a pending timeout from an earlier GO Negotiation start.

Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.
Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.

The network block bssid parameter can be used to force a specific BSS to
be used for a connection. It is also possible to modify this parameter
during an association. Previously, that did not result in any
notification to the driver which was somewhat problematic with drivers
that take care of BSS selection. Add a new mechanism to allow
wpa_supplicant to provide a driver update if the bssid parameter change
for the current connection modifies roaming policy (roaming
allowed/disallowed within ESS).

If a TX status event and RX event for a GO Negotiation frame gets
delayed long enough to miss the initial wait, it was possible for
reception of a GO Negotiation Response frame with status 1 to try to
initiate a new p2p-listen work item to wait for the peer to become ready
while a previous p2p-listen was already in progress due to that earlier
timeout while waiting for peer. This would result in the new
start_listen request getting rejected ("P2P: Reject start_listen since
p2p_listen_work already exists") and the negotiation not proceeding.
Work around this by using P2P_WAIT_PEER_CONNECT state instead of
P2P_WAIT_PEER_IDLE if P2P_CONNECT_LISTEN state has already been entered
when processing this special GO Negotiation Response status=1 case. This
can avoid double-scheduling of p2p-listen and as such, completion of the
GO negotiation even if the driver event or peer response are not
received in time (the response is supposed to be there within 100 ms per
spec, but there are number of deployed devices that do not really meet
this requirement).

Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.
Reduce the default startWhen value from 3 to 2 seconds for non-WPS case
since WPS builds have likely received most testing for the past years
with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else
require the EAPOL-Start to initiate operation after a connection.

The internal entropy pool was previously used to prevent 4-way handshake
in AP mode from completing before sufficient entropy was available to
allow secure keys to be generated. This commit extends that workaround
for boards that do not provide secure OS level PRNG (e.g., /dev/urandom
does not get enough entropy) for the most critical WPS operations by
rejecting AP-as-enrollee case (use of AP PIN to learn/modify AP
configuration) and new PSK/passphrase generation. This does not have any
effect on devices that have an appropriately working OS level PRNG
(e.g., /dev/random and /dev/urandom on Linux).
