EAP peer does not expect data present when beginning the Phase 2 in
EAP-{TTLS,PEAP} but in TLS 1.3 session tickets are sent after the
handshake completes.
There are several strategies that can be used to handle this, but this
patch picks up from the discussion[1] and implements the proposed use of
SSL_MODE_AUTO_RETRY. SSL_MODE_AUTO_RETRY has already been enabled by
default in OpenSSL 1.1.1, but it needs to be enabled for older versions.
The main OpenSSL wrapper change in tls_connection_decrypt() takes care
of the new possible case with SSL_MODE_AUTO_RETRY for
SSL_ERROR_WANT_READ to indicate that a non-application_data was
processed. That is not really an error case with TLS 1.3, so allow it to
complete and return an empty decrypted application data buffer.
EAP-PEAP/TTLS processing can then use this to move ahead with starting
Phase 2.

SSL_CTX_get0_certificate() returns NULL if no certificate is installed.
While this should not be the case here due to the loop in
openssl_debug_dump_certificate_chains() proceeding only if the
SSL_CTX_set_current_cert() returns success, it is safer to make
openssl_debug_dump_certificate() explicitly check against NULL before
trying to dump details about the certificate.

This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).
Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.
Note that due to the use of thin archives, this required
building with absolute paths.

Instead of building in the source tree, put most object
files into the build/ folder at the root, and put each
thing that's being built into a separate folder.
This then allows us to build hostapd and wpa_supplicant
(or other combinations) without "make clean" inbetween.
For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.

Explicit configuration to enable TLS v1.0 and/or v1.1 did not work with
systemwide OpenSSL secpolicy=2 cases (e.g., Ubuntu 20.04). Allow such
systemwide configuration to be overridden if the older TLS versions have
been explicitly enabled in the network profile. The default behavior
follows the systemwide policy, but this allows compatibility with old
authentication servers without having to touch the systemwide policy.

The previous implementation used mp_rand_prime() to generate a random
value in range 0..m. That is insanely slow way of generating a random
value since mp_rand_prime() is for generating a random _prime_ which is
not what is needed here. Replace that implementation with generationg of
a random value in the requested range without doing any kind of prime
number checks or loops to reject values that are not primes.
This speeds up SAE and EAP-pwd routines by couple of orders of
magnitude..

It looks like EVP_PKEY_derive() may change the returned length of the
buffer from the initial length determination (NULL buffer) to the

ECDH result has been used with extra data (zeros in the end) with OWE or

BN_bn2bin_padded() broke this function for cases where no padding is
used (padlen == 0). Those would have always failed after the changes and

hostap.git, so this did not have any real issues, but anyway, better fix
this function to match its documentation.

hostapd EAP server can now be configured with two separate server
certificates/keys to enable parallel operations using both RSA and ECC
public keys. The server will pick which one to use based on the client
preferences for the cipher suite (in the TLS ClientHello message). It
should be noted that number of deployed EAP peer implementations do not
filter out the cipher suite list based on their local configuration and
as such, configuration of alternative types of certificates on the
server may result in interoperability issues.

This adds support for a new EAP method: EAP-TEAP (Tunnel Extensible
Authentication Protocol). This should be considered experimental since
RFC 7170 has number of conflicting statements and missing details to
allow unambiguous interpretation. As such, there may be interoperability
issues with other implementations and this version should not be
deployed for production purposes until those unclear areas are resolved.
This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to
allow arbitrary data to be specified as the contents of the message.
