The directory /etc/libvirt is backed up on uninstallation and is
restored on installation.
Alle Files in /var are commented in the rootfile so they are not
removed on uninstallation.
Because of the fact that the directories are not shipped with the
package they were created at installation time.
The permissions of 3 directories are changed because the qemu user is
nobody and the qemu group is kvm, so the permissions must be nobody:kvm

Includes various security fixes:
* sshd(8): Mitigate a potential denial-of-service attack against
the system's crypt(3) function via sshd(8). An attacker could
send very long passwords that would cause excessive CPU use in
crypt(3). sshd(8) now refuses to accept password authentication
requests of length greater than 1024 characters. Independently
reported by Tomas Kuthan (Oracle), Andres Rojas and Javier Nieto.
* sshd(8): Mitigate timing differences in password authentication
that could be used to discern valid from invalid account names
when long passwords were sent and particular password hashing
algorithms are in use on the server. CVE-2016-6210, reported by
EddieEzra.Harari at verint.com
* ssh(1), sshd(8): Fix observable timing weakness in the CBC padding
oracle countermeasures. Reported by Jean Paul Degabriele, Kenny
Paterson, Torben Hansen and Martin Albrecht. Note that CBC ciphers
are disabled by default and only included for legacy compatibility.
* ssh(1), sshd(8): Improve operation ordering of MAC verification for
Encrypt-then-MAC (EtM) mode transport MAC algorithms to verify the
MAC before decrypting any ciphertext. This removes the possibility
of timing differences leaking facts about the plaintext, though no
such leakage has been observed. Reported by Jean Paul Degabriele,
Kenny Paterson, Torben Hansen and Martin Albrecht.
* sshd(8): (portable only) Ignore PAM environment vars when
UseLogin=yes. If PAM is configured to read user-specified
environment variables and UseLogin=yes in sshd_config, then a
hostile local user may attack /bin/login via LD_PRELOAD or
similar environment variables set via PAM. CVE-2015-8325,
found by Shayan Sadigh.

The perl-Net-IP module provides various methods for validating
and calculating IP-addresses (both IP protocols supported) and
is a runtime dependency of guardian 2.0.

Add support and usage of the recently introduced feature of
including other files in the ignore file to add
the red related IP-addresses to the ignore list on IPFire
systems.
Also use reload-ignore-list feature instead of reloading the
whole configuration on ignore list modifications.

This function is responsible for collecting all required data,
like the green, blue, orange (if the interfaces are available),
red, gateway and used DNS server IP-addresses.
It will add als these addresses and the configured and enabled
user-defined ignored addresses/networks to the ignore file of
guardian to prevent from blocking any of them.
Note:
The IPFire and RED inteface related addresses also will be added
to the ignore file, even if there is no user-defined entry in the
list.

The CGI now uses an own ignored configuration file for
storing host addresses and/or subnets which should be
ignored by guardian.
This allows to add remarks for them and to enable or disable
each entry individally at any time.
