--------------------------------
Resolution: Fixed
> intermediate certificate chain loading can miss certificates
> ------------------------------------------------------------
>
> Key: TS-4619
> URL: https://issues.apache.org/jira/browse/TS-4619
> Project: Traffic Server
> Issue Type: Bug
> Components: SSL
> Reporter: James Peach
> Assignee: Susan Hinrichs
> Fix For: 7.0.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> When loading intermediate SSL certificates, the original code used
> {{SSL_CTX_add_extra_chain_cert_file}} which adds all the certificates in the
> file.
> The new code uses {{SSL_CTX_add0_chain_cert}} and passes it a single {{X509
> *}}, so it only ends up loading the first intermediate rather than all of
> them.
> This code occurs in 3 places with ugly {{#ifdefs}}. The right thing to do
> here is to call {{SSL_CTX_add_extra_chain_cert_file}} in every place and
> inside {{SSL_CTX_add_extra_chain_cert_file}} use {{SSL_CTX_add0_chain_cert}}
> if it is available.
> Also take a look at the place where the server certificate is loaded. This is
> also allowed to be a bundle, so we can call
> {{SSL_CTX_add_extra_chain_cert_file}} again to avoid the code duplication,
> though at this point we already have a {{BIO}} in hand that we would need to
> use.
