fix TLS version gating in tests/quic.c;
fix gating in src/ssl.c for wolfSSLv2_client_method() and wolfSSLv2_server_method();
reorganize prototypes in wolfssl/ssl.h for wolf*_method*() to group systematically by protocol version and gate correctly on support for that version in the build.
- new internal field for keeping early data enabled status,
as QUIC does not call SSL_write_early_data() itself.
- using read_/write_early_data() methods in QUIC handshake
when early data is enabled. This triggers the internals
that emit the proper early data indication handlings.
Also:
* added HAVE_FALCON guards as needed.
* corrected minor falcon bugs as I found them.
* handling OID sum collision between DILITHIUM_LEVEL5 and DILITHIUM_AES_LEVEL3
Tested with the following commands:
examples/server/server -v 4 -l TLS_AES_256_GCM_SHA384 \
-c ~/tmp/dilithium_aes_level5_entity_cert.pem \
-k ~/tmp/dilithium_aes_level5_entity_key.pem \
-A ~/tmp/dilithium_aes_level5_root_cert.pem --pqc P521_KYBER_LEVEL5
examples/client/client -v 4 -l TLS_AES_256_GCM_SHA384 \
-c ~/tmp/dilithium_aes_level5_entity_cert.pem \
-k ~/tmp/dilithium_aes_level5_entity_key.pem \
-A ~/tmp/dilithium_aes_level5_root_cert.pem --pqc P521_KYBER_LEVEL5
with permutations of SHAKE,AES variants and levels 2,3,5
Support wolfSSL_CTX_set1_curves_list being available when X25519 and/or
X448 only defined.
Don't recognize X25519 or X448 if corresponding define is not set.
Enable test in api.c.
Add support for parsing and verifying certificates with RSA-PSS
signatures. Including check PSS parameters in key with those in
signature algorithm.
Add support for parsing private RSA PSS key.
Add support for parsing public RSA PSS key.
added numerous missing _SMALL_STACK code paths (PK objects on the stack);
in settings.h, enable WOLFSSL_SMALL_STACK_STATIC by default when WOLFSSL_SMALL_STACK is defined (NO_WOLFSSL_SMALL_STACK_STATIC to override);
fixes for unsafe strcat()s in tests/quic.c;
fix for unsafe macro WOLFSSL_IS_QUIC();
fix to exclude quic from enable-all when enable-linuxkm (quic needs opensslextra, and opensslextra currently only works in-kernel in cryptonly builds);
fix for signed/unsigned clash in wolfSSL_quic_receive().
In test with ngtcp2 example client using openssl, session resumption
against a QUIC wolfssl server failed. The error was tracked down to
wolfSSL believing EaryData needs to be handled and returning SUCCESS
from wolfSSL_SSL_do_handshake() after the server Finished had been
sent.
However the handshake was not complete and ngtcp2 invoked the
post_handshake processing for new data arriving from the client.
This failed a check in post processing that the ssl->handShakeState
actually was HANDSHAKE_DONE.
The workaround in this PR repeats do_handshake until the ssl
state acually says it is complete. This way, session resumption works.
Either this alternative do_handshake() is merged for QUIC protocol
hanlders. Or we need to fix the 'normal' do_handshake() to no return
SUCCESS when early data is expected on a QUIC WOLFSSL.
use camel case not underscores in variable names;
restore use of const int variables for buffer sizes in several spots (for ease of smallstack code paths should they be needed);
use more MISRAish flow control in X509PrintSignature().
also, capture the retval from several more snprintf()s to pass directly to wolfSSL_BIO_write(), avoiding frivolous strlen()s.
fix various possible buffer overruns;
fix various runtime-error-driven memory leaks;
various refactors for efficiency, clarity, and safety, including refactors to eliminate unsafe XSTRNCAT() calls.
We have users who need to debug errors coming out of libwolfssl in production,
where --enable-debug isn't an option. Our error queue implementation is the
solution, but our usage of WOLFSSL_ERROR isn't consistent. This commit greatly
expands our usage of WOLFSSL_ERROR. There are too many error cases to tackle
all at once, and not all error cases are particularly meaningful or likely to be
hit in regular operation of the library. I've tried to focus on errors that
users are likely to hit, and I've chosen to ignore things like the mountain of
BUFFER_E and BAD_FUNC_ARG cases (for the most part). I've also tried to expand
WOLFSSL_ERROR usage in files where we haven't been using it historically
(e.g. aes.c), so the pattern is now there for other developers to follow. In
order to prevent these additions from exploding the size of libwolfssl, they're
all behind a new macro, WOLFSSL_ERROR_VERBOSE. If WOLFSSL_VERBOSE_ERRORS is
defined, WOLFSSL_ERROR_VERBOSE just maps to WOLFSSL_ERROR.
