Hi Honza,

I'm confused, the commit I mentioned above is not in the range you
provided.  Besides, I can only include targeted security fixes for
exploitable vulnerabilities in a stable security update.  A pre-
authentication buffer overflow (CVE-2018-1084) most certainly qualifies,
while the msgio cleanup does not.  Missing checks for messages being
sent (08cb237) are hard to judge for me... wouldn't expoiting this
require root privileges to start with?  Also, how much of these issues
can be mitigated by enabling encryption or strict firewalling?
Basically, I'll need more ammo to push all these changes through the
Security Team.

(I'll package 2.4.4 for testing/unstable and eventually provide a stable
backport of it, but that goes through different channels.)
