9 years agoAdd gnutls_enable_pkcs11 option.
Phil Pennock [Sun, 24 Jun 2012 09:55:29 +0000 (02:55 -0700)]
Add gnutls_enable_pkcs11 option.

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.

Enable PCRE_CONFIG by default

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.
