bug#14774: 24.3.50; Warnings from gnutls under Fedora 19

[Lars Ingebrigtsen]

When doing gnutls connections under Fedora 19 with the current bzr
Emacs, I get the following warning:

gnutls.c: [1] Note that the security level of the Diffie-Hellman key exchange has been lowered to 256 bits and this may allow decryption of the session data

And that's what `gnutls-min-prime-bits' is defined as.

However, the gnutls-log-level is defined as 0, so we shouldn't get these
warnings.

LI> warnings.

Aha, I found the problem.  I'm setting the global log function, but not
the global "audit log" function which is issuing these.  That function
was added in GnuTLS 2.99, after I worked on the GnuTLS integration for
Emacs.

I was planning on requiring GnuTLS 3.x anyhow, so perhaps this can be
implemented with that rework instead of as a standalone change?

Sure; if it's likely that that will happen before the next Emacs
release.  :-)  Which I have no idea when is planned...

Check out this patch, which sets the audit log function correctly if
using GnuTLS 3.x and gives all audit messages level 1.  Does it work for
you?

I will ask separately about requiring GnuTLS 3.x.

[Lars Ingebrigtsen]

I'm no longer getting any warnings on Fedora 19, so I think your changes
fixed things.  Thanks!
