MEDIUM: ssl: Insert ocsp responses in update tree when needed
When 'ocsp-update' is enabled for a given certificate, we need to insert
the certificate_ocsp member of this certificate in the OCSP update tree
as well as the already existing OCSP response tree. For such an entry to
be created, the certificate needs to contain an "OCSP URI" field, and we
also need to know the certificate's issuer, that is used to build the
OCSP_CERTID. When no OCSP response is known for a given certificate, an
empty certificate_ocsp object gets created so that it can be inserted in
the ocsp update tree.
The entry is inserted on the first spot of the update tree since its
expire time is 0. Then whenever the update task is started, it will try
to get responses for those certificates first.
In order for the update process to work, we also need to store some
information relative to the main certificate into the certificate_ocsp
structure. This avoids having to keep a reference to a ckch in an ocsp
tree entry.
This patch adds a reference to the certificate chain as well as the ocsp
issuer that might have been filled during init into the certificate_ocsp
object. It also gets the ocsp uri at this time since it is contained in
the server's certificate. We only take the first uri that might be
contained in the certificate though.
Those fields are only filled when ocsp auto update is enabled for the
concerned certificate.
