Fabian Bläse 6bf01bb070 fff-mqtt: Remove unnecessary mosquitto server
The mosquitto server is not necessary for the intended use case of

Johannes Kimmel 450312e237 fff-layer3-config: add rules for router_ip
If the router_ips don't happen to be included in the client network's
subnet, the decision defaults to a main table lookup. This causes
packets to choose the wrong interface.

This patch forces packets from a router_ip to be routed via the fff table.

Fabian Bläse 5e7bdc0548 Drop support for devices with less than 8/64 MB flash/memory
Memory consumption has increased enough with OpenWrt 21.02, that
devices with 32 MB memory do not work reliably anymore.

It might be possible to work around the 4 MB flash limitation, but
reducing memory consumption is quite a bit harder. It is very likely
that this is only possible with a signifcant reduction of feature.

As we do not support any devices that have enough memory but only 4 MB
of flash, drop support for devices with less than 8/64 MB alltogether.

Fabian Bläse de9d4abf44 Retain old compat_version for sysupgrade compatibility
OpenWrt images contain a compat_version, which is used to block upgrades
to newer versions with incompatible configuration, if the configuration
cannot be migrated.

As we maintain our own configuration and all OpenWrt configuration files
are dropped on an upgrade, this upgrade block is not required.

To simplify the upgrade process, retain the old compat_version for the
next release. The compat_version should be bumped manually on release, so
we stay compatible with OpenWrt releases.

Fabian Bläse e07f6121cc fff-layer3-config: add router_ip option
For some purposes (e.g. SNAT, vxlan) it might be necessary to have an
additional address just for the router which is not attached to any
interfaces. Addresses like this are typically added to the loopback
interface.

The new options "router_ip" and "router_ip6" are added to the gateway
config to allow the user to configure such addresses. It is possible to
both specify the address with or without a subnet size.

The default configuration contains the IPv4 loopback address
(127.0.0.1/8) explicitly, but this is not necessary. These addresses are
configured automatically, even if they are not present in the
configuration, so they can safely be removed, if present.

The filters of our routing daemon babeld are adjusted accordingly, so
the newly added addresses are announced correctly.

The SIGHUP signal is sent to a process if a hangup is detected on the

Because ssh session disconnects might happen due to network
reconfiguration, aborting the test mode without restoring the old
settings might make the device unreachable.

Instead, disable the SIGHUP signal when test mode is activated, so
the script is either killed by the user (after successful configuration)
or the timer expires and the old settings are restored.

Receive packet steering (RPS) is a linux feature to improve forwarding
performance by distributing the forwarding of packets across multiple
cpus. This is necessary for network devices which have less queues than
cpu cores.

OpenWrt allows to enable RPS easily by setting the global option
'packet_steering' in the network configuration. With earlier OpenWrt
versions this option was enabled by default. However, the default value
was changed with OpenWrt 21.02.

Fabian Bläse 15d259b98a fff-network: add support for DSA switch configuration
Starting with OpenWrt 21.02 some devices now use upstream kernel drivers
for the built-in switch instead of relying on OpenWrt's swconfig driver.

The upstream kernel drivers use the Distributed Switch Architecture
(DSA) for configuration of the switch. Instead of explicitly configuring
the hardware switch, all ports appear as distinct interfaces and linux
bridges are offloaded to the hardware switch if possible.

To keep changes small, this patch adds support for DSA devices by
setting up a linux bridge, which is then treated just like the
cpuport-interface of the swconfig driver.

This exploits the existing WANDEV and SWITCHDEV variables to

the best route to the source address of a packet is via a different
interface.

Because there is no guarantee that routes have to be symmetric in the
Freifunk Franken backbone network, we cannot use strict mode. Because
default routes are used in the Freifunk Franken backone, loose mode
could be used, but does not make any sense. Instead, revert back to the
kernel default setting, which currently is 0 (disabled).

While this change affects both layer3 and node variant, nothing changes
for the node firmware, because it does not forward packets.

Fabian Bläse 764556b980 fff-network: Create separate interface for wan dhcp
Previously, an additional wan6 interface for SLAAC has been added, which
references the wan interface for its interface.
However, OpenWrt waits until the wan interface is completely up, until
it tries to start up interfaces that depend on it.

This not only can delay the configuration of IPv6 addresses
significantly, but also makes configuration of the wan6 interface
impossible in WAN networks with out a DHCP server.

To solve this issue, a separate interface wan4 for dhcp, which also
reference the wan interface, is created and the proto of wan is set to
none.

Adrian Schmutzler 539406d96b fff-network: fix primary port for Nanostation M
Migration from ar71xx to ath79 included changes to the ethernet/switch
driver for the target. This introduced a peculiar issue where
eth0 and eth1 are swapped for several devices. Most of the relevant
cases were already covered in 1cf4d762ff ("treewide: move devices
from ar71xx to ath79").

This switch also affects the Nanostation M, where the PoE-in port
is now eth1 und the PoE-out port is eth0. However, no action was
taken in the referenced patch, as nobody was aware of it then.

Since the Nanostation M is a two-port device, which we cannot
implement properly so far, it was implemented as a one-port with
the "primary" PoE-in port so far. This was broken by the ath79
introduction and is now fixed in this patch by using the one-port
setup on eth1. That way, the PoE-in port can now be switched by
ETHMODE as usual again.

Note that custom scripts, e.g. to set up the second port, need to
be adjusted manually, as that one is eth0 now.
