825476beda qemuSnapshotCreateActiveExternal: Remove duplicit assignment
The block of code pausing the VM assigns 'resume' to true but it's
already true because of the previous condition.

The code is deliberately kept in two blocks as upcoming changes will
modify both conditions.

a870801ae1 run: gracefully handle SIGHUP, SIGQUIT, SIGTERM
When using thue 'run' script to launch a daemon, it is intended to
temporarily stop the systemd units and re-start them again after.

When using this script over an SSH connection, it will get SIGHUP
if the connection goes away, and in this case it fails to re-start
the systemd units. We need to catch SIGHUP and turn it into a
normal python exception. For good measure we do the same for
SIGQUIT and SIGTERM too.  SIGINT already gets turned into an
exception by default which we handle.

2a95dbd03c nwfilter: drop support for legacy iptables conntrack direction
Long ago we adapted to Linux kernel changes which inverted the
behaviour of the conntrack --ctdir setting:

  commit a6a04ea47a
  Author: Stefan Berger <stefanb@us.ibm.com>
  Date:   Wed May 15 21:02:11 2013 -0400

    nwfilter: check for inverted ctdir

    Linux netfilter at some point (Linux 2.6.39) inverted the meaning of the
    '--ctdir reply' and newer netfilter implementations now expect
    '--ctdir original' instead and vice-versa.
    We check for the kernel version and assume that all Linux kernels with version
    2.6.39 have the newer inverted logic.

    Any distro backporting the Linux kernel patch that inverts the --ctdir logic
    (Linux commit 96120d86f) must also backport this patch for Linux and
    adapt the kernel version being tested for.

    Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

Given our supported platform targets, we no longer need to
consider a version of Linux before 2.6.39, so can drop
support for the old direction behaviour.

The test suite updates are triggered because that never
probed for the ctdir direction, and so the iptables syntax
generator unconditionally dropped the ctdir args.

02b8045517 nwfilter: drop support for legacy iptables match syntax
Long ago we adapted to iptables changes by introducing support

  commit 06844ccbaa
  Author: Stefan Berger <stefanb@us.ibm.com>
  Date:   Tue Aug 6 20:30:46 2013 -0400

    nwfilter: Use -m conntrack rather than -m state

    Since iptables version 1.4.16 '-m state --state NEW' is converted to
    '-m conntrack --ctstate NEW'. Therefore, when encountering this or later
    versions of iptables use '-m conntrack --ctstate'.

Given our supported platform targets, we no longer need to
consider a version of iptables before 1.4.16, so can drop
support for the old syntax.

The test suite updates are triggered because that never
probed for the new syntax, and so unconditionally
generated the old syntax.
