* Prepare pcks12 for opaque structs in libcryptotb2021-10-231-69/+70
| | | | | | | | | | | | | | | get_cert_chain() needs some error checking. return X509_V_ errors instead of trying to overload the NULL and then whine in a comment that this won't really work. Fix a bug that printed only the first attribute by factoring out the thing that did the actual printing. Sprinkle a few changes to accessors here and there. This is loosely based on what OpenSSL did with some simplifications by jsing. ok beck jsing
* Provide a way to determine our maximum legacy version.jsing2021-10-237-57/+62
| | | | | | | | | | | | | | With the introduction of TLSv1.3, we need the ability to determine our maximum legacy version and to track our peer's maximum legacy version. This is needed for both the TLS record layer when using TLSv1.3, plus it is needed for RSA key exhange in TLS prior to TLSv1.3, where the maximum legacy version is incorporated in the pre-master secret to avoid downgrade attacks. This unbreaks RSA KEX for the TLS client when the non-version specific method is used with TLSv1.0 or TLSv1.1 (clearly no one does this). ok tb@
* Add a regress test for TLS client/server.jsing2021-10-233-1/+496
| | | | | | | | | This currently exercises various combinations of TLS versions and their associated key exchange mechanisms. Note that this currently fails for TLSv1.0/TLSv1.1 with RSA KEX (to be fixed shortly). Over time all of the ssl regress should be moved into the dtls and tls regress tests.

* Untangle ssl3_get_message() return values.jsing2021-10-236-166/+139
| | | | | | | | | | | | | | | This function currently has a long return type that may be <= 0 on error/retry (which is then cast to an int in order to return it up the stack), or it returns the length of the handshake message (on success). This obviously means that 0 can be returned for both success and failure, which is the reason why a separate 'ok' argument has to exist. Untangle this mess by changing the return value to an int that indicates success (1) or error/retry (<= 0). The length never needs to actually be returned as it is already stored in s->internal->init_num (which is where the return value is read from anyway). ok tb@
