gnupg/dirmngr/validate.h
Werner Koch 831d014550
dirmngr: Add special treatment for the standard hkps pool to ntbtls.
* dirmngr/validate.h (VALIDATE_FLAG_SYSTRUST): Remove
(VALIDATE_FLAG_EXTRATRUST): Remove
(VALIDATE_FLAG_TRUST_SYSTEM): New.
(VALIDATE_FLAG_TRUST_CONFIG): New.
(VALIDATE_FLAG_TRUST_HKP): New.
(VALIDATE_FLAG_TRUST_HKPSPOOL): New.
(VALIDATE_FLAG_MASK_TRUST): New.
* dirmngr/validate.c (check_header_constants): New.
(validate_cert_chain): Call new function.  Simplify call to
is_trusted_cert.
* dirmngr/crlcache.c (crl_parse_insert): Pass
VALIDATE_FLAG_TRUST_CONFIG to validate_cert_chain
* dirmngr/server.c (cmd_validate): Use VALDIATE_FLAG_TRUST_SYSTEM and
VALIDATE_FLAG_TRUST_CONFIG.
* dirmngr/http-ntbtls.c (gnupg_http_tls_verify_cb): Check provided TLS
context.  Set trustclass flags using the new VALIDATE_FLAG_TRUST
values.

* dirmngr/certcache.c (cert_cache_init): Load the standard pool
certificate prior to the --hkp-cacerts.
--

Note that this changes the way the standard cert is used: We require
that it is installed at /usr/share/gnupg and we do not allow to change
it.  If this is not desired, the the standard cert can be removed or
replaced by a newer one.
