prepare their updates within hours or days due to the work done by SUSE,
Red Hat, and others on the distros list, hopefully in time before
attacks using the Qualys findings start or become widespread, but
nevertheless they are at a disadvantage.

People doing this might want to note that Icinga ran into problems
with the fix in RHEL/Centos kernels when using setrlimit to restrict
the stack size below the default.

The Red Hat ticket is currently locked but there's some information at
https://bugs.centos.org/view.php?id=13453.

Ah sorry about that, I've made

https://bugzilla.redhat.com/show_bug.cgi?id=1463241

public, kernel bugs default to private and then typically get opened up
(mostly because people have a tendency to put traces/dumps with
sensitive information in them and we don't want someone accidentally
exposing their SSH host keys or whatever).
