When resuming a session wolfSSL_SetSession unconditionally
overwrote ssl->version with the version stored in the cached
session, even if that version was below the WOLFSSL's configured
minDowngrade. The overwritten version then fed straight into
SendClientHello, so a client configured to require TLS 1.2 or
higher could still emit a ClientHello advertising e.g. TLS 1.0
when resuming an old cached session. The ServerHello path catches
the actual downgrade, but the ClientHello version is already a
protocol-conformance issue and can confuse middleboxes.
Reject the session if its stored minor version is below
ssl->options.minDowngrade. The check is DTLS-aware: DTLS minor
versions decrease as the protocol version increases, so the
direction of the comparison is flipped for DTLS.
F-2105
The signature algorithm specified in CertificateVerify must have been in
the CertificateRequest. Add check.
The cipher suite test cases, when client auth and RSA are built-in and
use the default client certificate and use the *-ECDSA-* cipher
suites, no longer work. The client certificate must be ECC when the
cipher suite has ECDSA. Don't run them for that build.
