This was not a new check!  The call to gnutls_dh_set_prime_bits() was
made with DH_BITS in Exim 4.77, so the only difference is that now an

Test suite fixes, mostly for new certs.

This fixes OpenSSL ones too.

the test output just hadn't been updated to match the munging.

10 years agoGnuTLS pretty much passes test suite. exim-4_80_RC1
Phil Pennock [Fri, 18 May 2012 03:04:36 +0000 (23:04 -0400)]
GnuTLS pretty much passes test suite.

Fixed assumption that tls_certificate non-NULL in server when TLS
advertised.
Weakened an !S_ISREG() to an S_ISDIR() to keep the test-suite happy.

Using:
  do { rc = gnutls_handshake(state->session);
  } while ((rc == GNUTLS_E_AGAIN) || (rc == GNUTLS_E_INTERRUPTED));
is contra-indicated when you expect SIGALRM to be able to break you out
of the loop.  A little _too_ robust there.  Switching last part to:
  (rc == GNUTLS_E_INTERRUPTED && !sigalrm_seen)
is rather more productive.

Only test not passing is 2025, which makes major assumptions about
cipher suites and needs to be revisited to see what it's trying to
achieve.  We fail the test because we successfully deliver the message
without expected errors, because other ciphersuites are available, since
we're no longer limited to a *very* short list embedded in the Exim
code.  That sort of failure I can live with.

More GnuTLS cleanups/fixes.

Decided "unknown (reason)" in tls_peerdn was wrong, stripped that, added
replacement guard.

Moved cipherbuf construction to where it makes more sense, where peerdn
is extracted, so that setting the exim vars gets back closer to just
some pointer switching.

Fix missing failure check after handshake in client.

Fix tls.c tls_ungetc() and friends by pointing watermark vars at state
content.

Regenerated test-suite D-H params so we don't have too small values,
which was causing connection rejections.

Test-suite output where new test cert info is logged (there will be a
couple more, when I fix a lingering problem with tls_peerdn being unset

Get TLS SNI server-switching working with GnuTLS.

Registering a cert/key in an x509 credentials *adds* them, and there's
no way to remove them, so we need a shiny new x509_cred each time the
key/cert change.

Since we avoid re-expanding unless tls_sni appears in tls_certificate,
we've mostly avoided the expense unless SNI is in use, and the extra
loading should be minimal, as everything should be in buffer/cache from
a few microseconds beforehand.

extensions, with servername, and verifying we do now get the correct

In older versions, the vaguely_random_number() function just immediately
calls the fallback, so it's the same as before this change (just one
extra indirection in the code-path).

Define a constant of 1024 for dh-bits for use in those old releases
where GnuTLS won't tell us how many we should use.

Change the on-disk filename for generated D-H params again, replacing
the -normal with -<bitcount>, so that it's 1024 or whatever, and as
the value changes, Exim will automatically start using the new value.
