I don't see any obvious leaks (although I'm unfamiliar with OpenSSL semantics),
but using a goto is generally frowned upon. Better code might be something
like this:
+ certs = d2i_X509(NULL, &tmp, lengthOfCert);
+ if (certs == NULL) {
+ ERR_error_string(ERR_get_error(), err);
+ tcn_Throw(e, "Error reading certificate (%s)", err);
+ rv = JNI_FALSE;
+ } else if (SSL_CTX_add0_chain_cert(c->ctx, certs) <= 0) {
+ ERR_error_string(ERR_get_error(), err);
+ tcn_Throw(e, "Error setting certificate (%s)", err);
+ rv = JNI_FALSE;
+ }
+
+ free(cert);
+ return rv;

This needs a review by someone who knows C better than I do.
The implementation is essentially a copy/paste of setCertificateRaw with
what looked to be the right changes to remove the unnecessary private
key code and to call the right OpenSSL method to set the chain.
It does work - in that SSL Labs sees the full chain - but the code may
well be terrible. I wouldn't be surprised if it leaked memory.
Once this has been reviewed and fixed, I plan to do a tc-native release
so we can up the minimum required version in 9.0.x and 8.5.x and ship
the next releases with the necessary tc-native code to use this feature.
