Pull request overview
This PR adjusts the POSIX TLS transport’s server-side peer verification behavior so that when peer verification is enabled, the server requires the client to present a certificate (mTLS), aligning the transport behavior with “require peer cert” expectations.
Changes:
- Extends
LoadTlsCertificates()with anis_serverflag to differentiate client vs server verification behavior. - In server mode (and when peer verification is not disabled), sets
WOLFSSL_VERIFY_PEER | WOLFSSL_VERIFY_FAIL_IF_NO_PEER_CERTto require a client certificate. - Updates TLS client/server initialization paths to pass the new
is_serverflag.
