The new tls_connection_set_success_data(),
tls_connection_set_success_data_resumed(),
tls_connection_get_success_data(), and tls_connection_remove_session()
functions can be used to mark cached sessions valid and to remove
invalid cached sessions. This commit is only adding empty functions. The
actual functionality will be implemented in followup commits.

Commit 94f1fe6f63 ('Remove master key
extraction from tls_connection_get_keys()') left only fetching of
server/client random, but did not rename the function and structure to
minimize code changes. The only name is quite confusing, so rename this
through the repository to match the new purpose.

This adds a new STATUS command field "eap_tls_version" that shows the
TLS version number that was used during EAP-TLS/TTLS/PEAP/FAST exchange.
For now, this is only supported with OpenSSL.

This mechanism to figure out TLS library capabilities has not been used
since commit fd2f2d0489 ('Remove
EAP-TTLSv1 and TLS/IA') (Sep 2011).

The internal TLS implementation started rejecting number of unsupported
configuration parameters recently, but those new error paths did not
free the allocated tlsv1_credentials buffer.

This function exposes internal state of the TLS negotiated parameters
for the sole purpose of being able to implement PRF for EAP-FAST. Since
tls_connection_prf() is now taking care of all TLS-based key derivation
cases, it is cleaner to keep this detail internal to each tls_*.c
wrapper implementation.

This is similar with domain_suffix_match, but required a full match of
the domain name rather than allowing suffix match (subdomains) or
wildcard certificates.

This new wpa_supplicant and hostapd control interface command can be
used to determine which TLS library is used in the build and what is the
version of that library.

This TLS configuration parameter is explicitly for OpenSSL. Instead of
ignoring it silently, reject any configuration trying to use it in
builds that use other options for TLS implementation.

Validation of these parameters has not been implemented in the internal
TLS implementation. Instead of ignoring them silently, reject the
configuration to avoid giving incorrect impression of the parameters
being used if wpa_supplicant is built with the internal TLS
implementation instead of the default OpenSSL.

The internal TLS server implementation and RADIUS server implementation
in hostapd can be configured to allow EAP clients to be tested to
perform TLS validation steps correctly. This functionality is not
included in the default build; CONFIG_TESTING_OPTIONS=y in
hostapd/.config can be used to enable this.
When enabled, the RADIUS server will configure special TLS test modes
based on the received User-Name attribute value in this format:
<user>@test-tls-<id>.<rest-of-realm>. For example,
anonymous@test-tls-1.example.com. When this special format is used, TLS
test modes are enabled. For other cases, the RADIUS server works
normally.
The following TLS test cases are enabled in this commit:
1 - break verify_data in the server Finished message
2 - break signed_params hash in ServerKeyExchange
3 - break Signature in ServerKeyExchange
Correctly behaving TLS client must abort connection if any of these
failures is detected and as such, shall not transmit continue the
session.

This allows the internal TLS implementation to write log entries to the
same authlog with rest of the RADIUS server and EAP server
functionality.

Reassemble partial TLS records to make the internal TLS client
implementation more convenient for stream sockets.

These protocols seem to be abandoned: latest IETF drafts have expired
years ago and it does not seem likely that EAP-TTLSv1 would be
deployed. The implementation in hostapd/wpa_supplicant was not complete
and not fully tested. In addition, the TLS/IA functionality was only
available when GnuTLS was used. Since GnuTLS removed this functionality
in 3.0.0, there is no available TLS/IA implementation in the latest
version of any supported TLS library.
Remove the EAP-TTLSv1 and TLS/IA implementation to clean up unwanted
complexity from hostapd and wpa_supplicant. In addition, this removes
any potential use of the GnuTLS extra library.
This phase1 parameter for TLS-based EAP methods was already supported
with GnuTLS and this commit extends that support for OpenSSL and the
internal TLS implementation.
This converts tls_connection_handshake(),
tls_connection_server_handshake(), tls_connection_encrypt(), and
tls_connection_decrypt() to use struct wpa_buf to allow higher layer
code to be cleaned up with consistent struct wpabuf use.
When the TLS handshake had been completed earlier by the server in case of
abbreviated handshake, the output buffer length was left uninitialized. It
must be initialized to zero in this case. This code is used by EAP-FAST
server and the uninitialized length could have caused it to try to send a
very large frame (though, this would be terminated by the 50 roundtrip EAP
limit). This broke EAP-FAST server code in some cases when PAC was used to
establish the tunnel.
