The dirmngr may need to get a certificate from gpgsm's store in the

gpgsm: Always use the chain model if the root-CA requests this.
* sm/call-dirmngr.c (gpgsm_dirmngr_isvalid): Do not use
option --force-default-responder.
* sm/certchain.c (is_cert_still_valid): Rename arg for clarity.
(gpgsm_validate_chain): Always switch to chain model.
--

The trustlist.txt may indicate that a root CA issues certificates
which shall be validated using the chain model.  This is for example
the case for qualified signatures.  Before this change we did this
only if the default shell model indicated that a certificate has
expired.  This optimization is technically okay but has one problem:
The chain model requires the use of OCSP but we switch to this only
when running the chain model validation.  To catch revoked
certificates using OCSP we need to always switch to the chain model
unless OCSP has been enabled anyway.

Note that the old --force-default-responder option is not anymore
used.

Test cases are certificates issued by

  # CN=TeleSec qualified Root CA 1
  # O=Deutsche Telekom AG
  # C=DE
  # 2.5.4.97=USt-IdNr. DE 123475223

I did some test against

  Governikus_Signer:       2.9.2.0
  MCard security Provider: 2.4.0
  Algorithm catalog from:  05.12.2019

using a Signature Card v2.0 and a nistp256 certificate.  Encrypting
with Governikus used the stdDH-sha1kdf scheme which we can now
decrypt.  Encrypting with GPGSM uses for that curve the recommended
scheme sha256kdf but Governikus was not able to decrypt this (no
usable error message).  Encrypting using stdDH-sha1kdf with GPGSM by
using the new --debug-force-ecdh-sha1kdf option showed that
Governikus was able to decrypt this.

FWIW: RFC5753 (Use of Elliptic Curve Cryptography (ECC) Algorithms)
has this requirement:

   Implementations that support EnvelopedData with the
   ephemeral-static ECDH standard primitive:

   - MUST support the dhSinglePass-stdDH-sha256kdf-scheme key
     agreement algorithm, the id-aes128-wrap key wrap algorithm, and
     the id-aes128-cbc content encryption algorithm; and

which Governikus seems not to fulfill.

If the issuer does not provide a DP and the user wants such an issuer,
we expect that a certificate does not need revocation checks.  The new

old behaviour which requires that a suitable LDAP server has been
configured to lookup a CRL by issuer.

See the code for a description of the problem. Tested using the certs
from the bug report and various command lines

  gpgsm --faked-system-time=XXXX --disable-crl-checks \
         -ea -v --debug x509  -r 0x95599828

with XXXX being 20190230T000000 -> target cert too young
with XXXX being 20190330T000000 -> okay
with XXXX being 20190830T000000 -> okay, using the long term cert
with XXXX being 20220330T000000 -> target cert expired

The --disabled-crl-checks option is required because in our a simple
test setting dirmngr does not know about the faked time.

There was no way to specify an LDAPS server in
dirmngr_ldapserver.socnf or with gpgsm's --keyserver option.  This
patch fixes this.  Eventually we should allow to replace host and port
by a partial URI in the same way ldap_initialize does it.  For backward
compatibility we do not yet do that.

Although the dirmngr code accepts an URL (eg. taken from a
certificate), I can't see how the scheme was ever used.  Thus the
patch also detects an ldaps scheme and uses this.  That part has not
been tested, though.

As described in my report T1644, it is possible that multiple
certificates exist with the same Distinguished Name and the same key.
In this case, verifying S/MIME signatures and other actions fail with
"certificate not found: Ambiguous name". For details see the bug
report.

To circumvent the problem, I am patching GnuPG since 2014 so that in
this case the newest of the ambiguous certificates is used.

This is not an ultimate solution of the problem: You should try every
certificate with the same DN until verification succeeds or until all
certificates fail, and if multiple certificates of a chain are
ambiguous you even have to check every combination. You may even
consider checking the keyUsage attributes of the ambiguous certificates
to reduce the number of combinations.

But in the existing case of the certificates in the German Research
Network (DFN) PKI where the newest one is the valid one and all
ambiguous certificates have the same keyUsage attributes, this patch
has proven to be sufficient over the last three years.

With every GnuPG update, I have adapted the patch, luckily I never
needed to change anything except line numbers.

This new option can be used to detect ROCA affected keys.  To scan an
entire keyring and print the affected fingerprints use this:

  gpg -k --with-key-screening --with-colons | gawk -F: \
       '$1~/pub|sub|sec|ssb|crt/ && $18~/\<6001\>/ {found=1;next};
        $1=="fpr" && found {print $10}; {found=0}'

The same works for gpgsm.  Note that we need gawk due to the "\<" in
the r.e.
