2012-06-25Let Linux makefile inherit CFLAGS/CFLAGS_DYNAMIC.Phil Pennock
Pulled from Debian 30_dontoverridecflags.dpatch by Andreas Metzler. We just add CFLAGS_DYNAMIC too and some comments. Non-POSIX syntax, but fairly portable; GNU make gained it in 1998, we believe even very old systems should handle it fine.
2012-06-24Add gnutls_enable_pkcs11 option.Phil Pennock
GnuTLS 2.12.0 adds PKCS11 support using p11-kit and by default will autoload modules, which interoperates badly with GNOME keyring integration, configured via paths in environment variables, and Exim invoked by the user (eg, mailq) will then try to load the modules, fail and spew warnings from the module for a library loaded by a library. http://www.gnu.org/software/gnutls/manual/gnutls.html#Smart-cards-and-HSMs documents that to prevent this, explicitly init PKCS11 before calling gnutls_global_init(). So we do so, unless the admin sets the new option. Reported by Andreas Metzler, who confirmed that the added calls fixed the problem for him.

2012-05-30Revert "Lower EXIM_CLIENT_DH_MIN_BITS 1024 -> 512."exim-4_80Phil Pennock
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.

Wolfgang Breyha saw a real-world site using 768 bits.

2012-05-23_ISOC99_SOURCE -> _GNU_SOURCEexim-4_80_RC5Phil Pennock
_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.
2012-05-23Define _ISOC99_SOURCE in exim.hPhil Pennock
Done before os.h is pulled in so an OS can override it.

2012-05-23Doc: tls_require_ciphers examplesPhil Pennock
Note how to test strings, provide examples which distinguish port 25 from other ports. Carefully used short examples, but allows two different strings per implementation and demonstrates how the strings are very different.

2012-05-21features.h; tls_validate_require_cipher: log flag & testsexim-4_80_RC3Phil Pennock
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.
2012-05-20Update docs for latest state of TLS affairs.Phil Pennock
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.
2012-05-20Added tls_dh_max_bits & check tls_require_ciphers early.Phil Pennock
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.
