+Subject: [PATCH 1/3] _gnutls_pkcs11_verify_crt_status: check validity against
+ system cert
+
+To verify a certificate chain, this function replaces known
+certificates with the ones in the system trust store if possible.
+
+However, if it is found, the function checks the validity of the
+original certificate rather than the certificate found in the trust
+store.  That reveals a problem in a scenario that (1) a certificate is
+signed by multiple issuers and (2) one of the issuers' certificate has
+expired and included in the input chain.
+
+This patch makes it a little robuster by actually retrieving the
+certificate from the trust store and perform check against it.

+ expired
+
+gnutls_x509_trust_list_verify_crt2 use the macro SIGNER_OLD_OR_UNKNOWN
+to trigger the fallback verification path if the signer of the last
+certificate is not in the trust store.  Previously, it doesn't take
+into account of the condition where the certificate is expired.
