The new hostapd.conf radio_measurements parameter can now be used to
configure a test build to advertise support for radio measurements with
neighbor report enabled. There is no real functionality that would
actually process the request, i.e., this only for the purpose of minimal
STA side testing for now.

Previously, only WPA + WPA2 was covered. If FT is enabled in addition to
WPA, MDIE is included in the buffer between RSN and WPA elements. The
previous version ended up leaving only the MDIE after having skipped RSN
element. Fix this to skip MDIE as well to leave only WPA IE regardless
of whether FT is enabled in AP configuration.

The send_eapol() callback was used by driver_test.c, but with that
removed, there is no remaining users of the alternative EAPOL frame
transmitting mechanism in wpa_supplicant, i.e., all remaining driver
interfaces use l2_packet instead. Remove the send_eapol() to get rid of

Commit d4913c585e ('OpenSSL: Fix EAP-FAST
peer regression') introduced a workaround to use a new SSL_CTX instance
set for TLSv1_method() when using EAP-FAST. While that works, it is
unnecessarily complex since there is not really a need to use a separate
SSL_CTX to be able to do that. Instead, simply use SSL_set_ssl_method()
to update the ssl_method for the SSL instance. In practice, this commit
reverts most of the tls_openssl.c changes from that earlier commit and
adds that single call into tls_connection_set_params() based on EAP-FAST
flag.

Commit 35efa2479f ('OpenSSL: Allow TLS
v1.1 and v1.2 to be negotiated by default') changed from using
TLSv1_method() to SSLv23_method() to allow negotiation of TLS v1.0,
v1.1, and v1.2.
Unfortunately, it looks like EAP-FAST does not work with this due to
OpenSSL not allowing ClientHello extensions to be configured with
SSL_set_session_ticket_ext() when SSLv23_method() is used. Work around
this regression by initiating a separate SSL_CTX instance for EAP-FAST
phase 1 needs with TLSv1_method() while leaving all other EAP cases
using TLS to work with the new default that allows v1.1 and v1.2 to be
negotiated. This is not ideal and will hopefully get fixed in the future
with a new OpenSSL method, but until that time, this can be used allow
other methods use newer TLS versions while still allowing EAP-FAST to be
used even if it remains to be constraint to TLS v1.0 only.

Commit f5fa824e9a ('Update OpenSSL 0.9.8

there should be no valid users of the old API anymore and tls_openssl.c
can be cleaned up to use only the new API.

Some cases like ifconfig down/up may require MACsec restart. To make
sure the appropriate protect frames and replay parameters get configured
in cases where the interface was down, set these parameters from KaY
configuration to the driver before creating a new transmit SC. This
allows MACsec functionality to recover automatically on such restart.

Commit ac330cfd87 ('P2P: Reinvite with
social operation channel if no common channels') introduced a mechamisn
to reinvite a peer during a persistent group reinvocation from a GO with
a different operating channel proposal. This mechanism can fail if the
inviting device (GO) ends up getting a retransmitted, duplicated
Invitation Response frame processed second time while waiting for the
response to the retried Invitation Request (using one of the social
channels as the operating channel). IEEE 802.11 duplicate frame
detection mechanisms are supposed to prevent this type of sequence, but
not all drivers support those rules properly for pre-association frames,
including P2P Public Action frames.
Work around this issue by checking that the dialog token in the
Invitation Response frame matches the one from the last Invitation
Request if the special invitation retry mechanism is used. This is safer
to do now than to enable dialog token matching for all invitation cases.

It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.
It may be possible to allow the failed operation in cfg80211/mac80211,
but it looks better to work around this on wpa_supplicant side as well.
Try to unmask the 11b rates again on the next connection request if the
rate unmasking operation had failed.
