We do for direct usage of the CM, but I dont think anything for X509 STORE. |

Can you confirm you only want to return success or failure and not any other possible return codes? Old logic was >= 0 success else failure.
@douzzer does this need to be WC_NO_ERR_TRACE(WOLFSSL_FAILURE), etc?

Talked with douzzer, he said this should be OK.

@ColtonWilley the first half of the question still stands -- do we really want to be masking the true return code here?

Yes actually I believe we do. I believe openssl only returns 0 or 1, and uses X509_STORE_CTX_get_error for error reporting.

OpenSSL returns -1 on an error, 0 on verification failure, and 1 on verification success. This rework conforms to that API.

This could also be a crl so maybe better to use obj->data.ptr. Same effect just showing that we don't want to free anything the WOLFSSL_X509_OBJECT holds.

In the future it would be nice to up ref what gets put into the object list so that we can just call pop_free but that is not necessary on this PR.

Great catch on the CRLs. Agreed this whole thing could use a second pass at some point to take a close look at better using refcounts, but I think its large enough as is.

Why !WOLFSSL_SIGNER_DER_CERT here?

If !WOLFSSL_SIGNER_DER_CERT, CM internals do not hold onto the full DER buffer of the cert. In this case we need to keep a copy of it ourselves to meet requirements to return the chain. If WOLFSSL_SIGNER_DER_CERT, is defined, no need to keep a separate trusted stack as we can retrieve DER buffer from the underlying CM.
