Mathijs Kwik 97a3a99b40 firewall: options to select connection-tracking helpers
My main reason for adding this is the ability to turn off helpers
altogether. If you are not using any of the special protocols, keeping
them turned off is safest, and in case you do want to use them, it's
best to configure them through the new CT target for your network
topology. Perhaps some sane defaults for nixos can be examined in the
future.

This change has no impact if you don't touch the added options, so no
need to adapt.

Mathijs Kwik 6c62de6a31 firewall: option to enable the rpfilter netfilter module
This is meant to replace /proc/sys/net/ipv4/conf/*/rp_filter, which
only works for ipv4. Furthermore, it's nicer to handle this kind of
filtering in the firewall.

There are some more subtle differences, please see:
https://home.regit.org/netfilter-en/secure-use-of-helpers/

I chose to enable this by default (when the firewall is enabled) as
it's a good idea in general. Only people with advanced routing needs
might not want this, but I guess they don't use the nixos firewall
anyway and use a custom solution. Furthermore, the option only becomes
available in kernel 3.3+, so conservative nixos users that just stick
to the default kernel will not need to act now just yet.

Eelco Dolstra d4af6edd5e firewall.nix: Allow specifying trusted network interfaces
Trusted network interfaces (such as "lo") will accept any incoming
traffic.

Eelco Dolstra 3bc3dc3940 * Put the NixOS firewall ruleset in its own chain (‘nixos-fw’). This
should make it easier to compose with packages that set their own
  firewall rules, such as Nova or Libvirt.
* Provide a chain for accepted packets (‘nixos-fw-accept’), requested
  by Nicolas Pierron.

Eelco Dolstra e9b2ebcb99 * Send a TCP RST packet, rather than an ICMP port-unreachable packet,
for (apparently) open TCP connections that connection tracking 
  doesn't know about.  This prevents TCP connections to this machine
  from hanging in CLOSE_WAIT for a long time.

Eelco Dolstra 005ca15f64 * Firewall: add an option to allow extra firewall rules to be added.
* Firewall: change the policy of the INPUT chain back to ACCEPT to
  prevent a lockup when the Nix store is mounted over the network
  (i.e. in our VM tests).  This is because as soon as the policy is
  set to DROP, the iptables modules that enable access to the network
  filesystem cannot be acccessed anymore.

Eelco Dolstra f672aa71bf * RFC 4890 says that local nodes should not filter pretty much any
ICMPv6 messages (including echo requests), so don't do that.

Eelco Dolstra 0ea9f6611a * Add some more rules to allow ICMPv6 router/neighbour advertisements

  echo requests.
