- Advertises the build-time $hostname.local as a CNAME to the A and
AAAA records already advertised by Avahi
- Advertises a special network.local CNAME and provides a fastcgi
service on unix:/tmp/netbrowse.sock for browsing mDNS services
This commit also activates netbrowse by default with nginx listeing
to port 80 on IPv4 and IPv6 /browse by default but also / if called
with server name network.local.

With an increase in requests to confine users to the CLI, access using
SSH/SCP/SFTP to the configuration is becoming more and more important.
The admin role in Infix is mapped to the UNIX group 'wheel', meaning we
want all users in that group to be able to read and write files with
that ownership.
This patch fixes the initial ownership of startup-config, and /cfg, and
ensures the copy command in the CLI retain wheel group permissions.

Both L2 and L3 is supported.
With VLAN-filtering:
admin@infix-00-00-00:/config/interface/br0/> set bridge vlans vlan 1 multicast-filter 224.1.3.4 ports e0
Without VLAN-filtering:
admin@infix-00-00-00:/config/interface/br0/> set bridge multicast-filter 224.1.2.3 ports e0
- Rename mdb -> multicast-filters
- Add support for L2 multicast groups
- Change vlan, multicast and mulitcast-filters containers to presence
containers. This will result in that snooping will be disabled when
creating a bridge (or a vlan if vlan-filtered)
- Force the user to choose between VLANs and Multicast on top level bridge configuration
- Force L2 multicast to be state permanent
If an absolute path contains '../' we disallow it because what are you
doing, possible security violation.
Built-ins for running, startup, etc. remain as-is.

On any change to a container network interface we should schedule a
restart of the container to activate the changes. This code triggers
also at boot, when applying the whole startup-config, which initctl
handles by queuing any create/touch events for services.
This patch depends on the two previous commtis backporing fixes to
Finit's initctl tool and an upgrade of the k8s-logger.

In a host interface setup, i.e., moving an interface from the host to a
container, often using VETH pairs, any route should only be set when an
IP address has been set. This because the CNI ipam plugin, which we
use, require routes be part of ipam, which in turn requires an address.
For details, see <https://www.cni.dev/plugins/current/ipam/static/>

All querier functionality for IGMP now handled by mcd, even if there are
no VLAN interfaces on top of the bridge. Also, mcd now handles unique
query interval per interface, or per VLAN, so we no longer need multiple
daemons running.

This patch adds support for small incremental changes to bridge ports.
Changes where the libyang diff does not include a bridge reference so
that it will have to be synthesized from the current configuration.
For example, forgetting to set a port's PVID in a VLAN filtering bridge
setup, changing a bridge port's multicast flooding properties, or any
other per-bridge-port setting after the fact.
Fixes#349.

Temporary fix to prevent odd log messages. The fix is to add RAW VLAN
support to mcd so it can run as a proxy querier even if there is no

This patch adds validation of bridge port VLAN memberships and IP
addressing for VLAN filtering bridges:
1. Ports must be a member of this bridge
2. Ports cannot be tagged and untagged member at the same time
3. A VLAN filtering bridge does not support IP addressing
A VLAN filtering bridge can only be a tagged member of a VLAN. Any IP
addressing needs to be done using an upper VLAN interface.
NOTE: while technically possible break up these long must expressions
into multiple must expressions per node (split at 'and'), it will
break libyang in interesting ways that in turn make the confd
inference functionality stop working. E.g., creating VETH pairs.

This patch fixes a runtime error triggered by modifying an interface
currently used by a container. The CNI code must always return the
CNI status (reserved for container or not).
How to trigger:
- Create veth pair
- Make one end container-network and add to container
- Leave
- Return to configure and set an IP address on container interface
- Leave - BOOM

Simplify interface generation by collapsing eth_ and ethlike_ifaces to a
single list. Let gen_iface_json() determine interface type by querying
each interface. This allows us to create bridge setups also for qemu
use-cases.

In a VLAN filtering bridge setup we want to be able to support an
external IGMP/MLD querier running from userspace, because the bridge
multicast code can only generate proxy/NULL querys per VLAN.
This patch is a refactor to allow just that. If a VLAN on the bridge
has an upper interface, matching the bridge name and VID, we generate
a profile for querierd and enable the service.
For all other cases we try to disable any running querierd. It is up
to the daemon to figure out if it has a usable IP address to use as
the query source IP or use 0.0.0.0.
Since the logic for selecting a proper IP address must be handled by
the daemon in the per-VLAN setup, we revert back to also use it for
the stand-alone unfiltered bridge case as well.

An RFC conforming multicast snooping bridge should forward all unknown
multicast (IP & MAC) on ports where the mcast_flood flag is set. The
upstream kernel does not (yet) support this, but the KernelKit branch
of the kernel and iproute2 now support it.
