e2e9adc3d9 openssl: Disable padding after initializing the cipher suite
according to OpenSSL documentation [1], EVP_CIPHER_CTX_set_padding()
should be called after EVP_EncryptInit_ex(), EVP_DecryptInit_ex(), or
EVP_CipherInit_ex(). Not doing this causes EVP_CIPHER_CTX_set_padding()
to return false on OpenSSL-3.0.0, resulting in the impossibility to
connect in many scenarios. Fix this changing the order of function calls
where needed.

d265dd2d96 openssl: Remove deprecated functions from des_encrypt()
NetworkManager-CI detected systematic failures on test scenarios using
MSCHAPv2 when wpa_supplicant uses OpenSSL-3.0.0.
The 'test_module_tests.py' script also fails, and the following log is
shown:

 1627404013.761569: generate_nt_response failed
 1627404013.761582: ms_funcs: 1 error

It seems that either DES_set_key() or DES_ecb_encrypt() changed their
semantic, but it doesn't make sense to fix them since their use has been
deprecated. Converting des_encrypt() to avoid use of deprecated
functions proved to fix the problem, and removed a couple of build
warnings at the same time.

872609c151 EAP-TTLS/PEAP peer: Fix failure when using session tickets under TLS 1.3
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.

e364a34c69 OpenSSL: Make openssl_debug_dump_certificate() more robust
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.

87098d3324 build: Put archive files into build/ folder too
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.

722138cd25 build: Put object files into build/ folder
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.

eb595b3e3a wolfssl: Fix crypto_bignum_rand() implementation
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..
