* Revert "Lower EXIM_CLIENT_DH_MIN_BITS 1024 -> 512."exim-4_80Phil Pennock2012-05-303-11/+3
| | | | | | | | | | | | | This reverts commit 83f4c7515f3eb06dc070e78edd2694c1d088e5fd. 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 administrator can choose at compile time to change the lower bound. So keeping this at 1024 is not a regression and if we can't talk to them now, we couldn't before, and we shouldn't lower security by default. The reverted commit was only acceptable IF it was still better than what we had in Exim 4.77.

| | | | | | | | | | _ISOC99_SOURCE broke build on Linux (Ubuntu 11.10) because it broke <resolv.h>, <arpa/nameser.h>, etc. Their u_char and u_int usage relies upon BSD source being enabled too. So use _GNU_SOURCE.

| | | | | | | | | | | | | | | | | | With this, src/EDITME as Local/Makefile *only* needs EXIM_USER to be set and EXIM_MONITOR commented out for Exim to build on my box. I think this is a reasonable default; if there are releases of PCRE which do not include pcre-config, then on those boxes a slight change will be needed, but only where the file was already having to be edited anyway.

| | | | | | | | | | | | | | | | Pull in <features.h> on Linux. Switch readconf log from D_all (bug) to D_tls (though D_any would have worked). Modified runtest to handle clamped DH bits and tls_validate_require_cipher added debug logging.

* | Update docs for latest state of TLS affairs.Phil Pennock2012-05-202-16/+27
| | | | | | | | | | | | gnutls-params bits count no longer necessarily what GnuTLS says to use. The OpenSSL-vs-GnuTLS text needed some updating. Catches a ChangeLog addition made during the previous commit, so not picked up by it.
* | Added tls_dh_max_bits & check tls_require_ciphers early.Phil Pennock2012-05-2010-5/+293
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Janne Snabb tracked down the GnuTLS 2.12 vs NSS (Thunderbird) interop problems to a hard-coded limit of 2236 bits for DH in NSS while GnuTLS was suggesting 2432 bits as normal. Added new global option tls_dh_max_bits to clamp all DH values (client or server); unexpanded integer. Default value to 2236. Apply to both GnuTLS and OpenSSL (which requires tls_dh_params for this). Tired of debugging "SMTP fails TLS" error messages in mailing-lists caused by OpenSSL library/include clashes, and of finding out I typo'd in tls_require_ciphers only at the STARTTLS handshake. During readconf, fork/drop-privs/initialise-TLS-library. In that, if tls_require_ciphers is set, then validate it. The validation child will panic if it can't initialise or if tls_require_ciphers can't be parsed, else it exits 0. If the child exits anything other than 0, the main Exim process will exit.
* | Guard TLS SNI callback define better.Phil Pennock2012-05-201-1/+9
| | | | | | | | | | | | Guarded the callback invocation on OpenSSL having TLS extension support. Failed to guard the callback definition. Fixed. Problem spotted by Todd Lyons.
