Any messages retrieved from a query - either directly via

query. Retrieving the same message (i.e. corresponding to the same
message ID / database object) several times will always yield the same
C object.

The caller is allowed to destroy message objects owned by a query before
the query itself - which can save memory for long-lived queries.
However, that message must then never be retrieved again from that
query.

The python-notmuch2 bindings will currently destroy every message object
in Message._destroy(), which will lead to an invalid free if the same
message is then retrieved again. E.g. the following python program leads
to libtalloc abort()ing:

import notmuch2
db   = notmuch2.Database(mode = notmuch2.Database.MODE.READ_ONLY)
t    = next(db.threads('*'))
msgs = list(zip(t.toplevel(), t.toplevel()))
msgs = list(zip(t.toplevel(), t.toplevel()))

Fix this issue by creating a subclass of Message, which is used for
"standalone" message which have to be freed by the caller. Message class
is then used only for messages descended from a query, which do not need
to be freed by the caller.

verification whose results we throw away, because GMime doesn't offer
us any way to unwrap without doing signature verification.

smime: tests of X.509 certificate validity are known-broken on GMime < 3.2.7

When checking cryptographic signatures, Notmuch relies on GMime to
tell it whether the certificate that signs a message has a valid User
ID or not.

If the User ID is not valid, then notmuch does not report the signer's
User ID to the user.  This means that the consumer of notmuch's
cryptographic summary of a message (or of its protected headers) can
be confident in relaying the reported identity to the user.

However, some versions of GMime before 3.2.7 cannot report Certificate
validity for X.509 certificates.  This is resolved upstream in GMime
at https://github.com/jstedfast/gmime/pull/90.

We adapt to this by marking tests of reported User IDs for
S/MIME-signed messages as known-broken if GMime is older than 3.2.7
and has not been patched.

If GMime >= 3.2.7 and certificate validity still doesn't work for
X.509 certs, then there has likely been a regression in GMime and we
should fail early, during ./configure.

To break out these specific User ID checks from other checks, i had to
split some tests into two parts, and reuse $output across the two
subtests.

tests/smime: include secret key material for Bob

This is taken from the same Internet Draft that test/smime/ca.crt
comes from.  See that draft for more details.
https://www.ietf.org/id/draft-dkg-lamps-samples-02.html#name-pkcs12-object-for-bob

We don't use it yet, but it will be used to decrypt other messages in
the test suite.

Note that we include it here with an empty passphrase, rather than
with the passphrase "bob" that it is supplied with in the I-D.  The
underlying cryptographic material is the same, but this way we can
import cleanly into gpgsm without having a passphrase set on it (gpgsm
converts an empty-string passphrase into no passphrase at all on
import).

4 months agotest: Allow tests to have both gpg and gpgsm active at once

test: Allow tests to have both gpg and gpgsm active at once

Without this fix, we couldn't run both add_gnupg_home and
add_gpgsm_home in the same test script.

4 months agotests/smime: avoid copying the key+cert.pem around

tests/smime: avoid copying the key+cert.pem around

No functional change.

We no longer need to identify the key and cert to mml-mode when
sending an S/MIME message, so making a copy of key+cert.pem to
test_suite.pem is superfluous.  Get rid of the extra file.

4 months agotests/smime: Use gpgsm instead of openssl for mml creation of S/MIME msgs
Daniel Kahn Gillmor [Tue, 28 Apr 2020 18:57:13 +0000 (14:57 -0400)]
tests/smime: Use gpgsm instead of openssl for mml creation of S/MIME msgs

The documentation for message mode clearly states that EasyPG (which
uses GnuPG) is the default and recommended way to use S/MIME with
mml-secure:

[0] https://www.gnu.org/software/emacs/manual/html_node/message/Using-S_002fMIME.html

To ensure that this mode works, we just need to import the secret key
in question into gpgsm in addition to the public key.  gpgsm should be
able pick the right keys+certificates to use based on To/From headers,
so we don't have to specify anything manually in the #secure mml tag.

The import process from the OpenSSL-preferred form (cert+secretkey) is
rather ugly, because gpgsm wants to see a PKCS#12 object when
importing secret keys.

Note that EasyPG generates the more modern Content-Type:
application/pkcs7-signature instead of application/x-pkcs7-signature
for the detached signature.

We are also obliged to manually set gpgsm's include-certs setting to 1
because gpgsm defaults to send "everything but the root cert".  In our
weird test case, the certificate we're using is self-signed, so it
*is* the root cert, which means that gpgsm doesn't include it by
default.  Setting it to 1 forces inclusion of the signer's cert, which
satisfies openssl's smime subcommand. See https://dev.gnupg.org/T4878
for more details.
