Fabian Bläse 41b4168290 fff-network: Do not configure switch for ONE and TWO_PORT devices
In a previous change all static configuration has been moved from
configurenetwork to a static uci-defaults script. As the configuration
of the switch is completely static, while port assignment for ONE and
TWO_PORT devices is dynamic, this patch slightly changed the condition
for the creation of the switch config.

Instead of only configuring the switch, if ONE_PORT and TWO_PORT is not
set, the switch is now always configured if a swconfig device is
present. However, some ONE and TWO_PORT devices have a swconfig device,
even though only a single physical port is connected to it. Those
devices require an unconfigured switch to function properly.

Therefore, introduce additional conditions, so the switch configuration
is not generated if ONE_PORT or TWO_PORT is set.

Fixes: 1c3328e64a ("Remove static configuration from dynamic script")

Fabian Bläse 240a506ee7 fff-network: convert GL-AR150 to TWOPORT
The GL-AR150 has two ethernet ports. One of them is connected directly
to the CPU (labeled "WAN"), while the other one (labeled "LAN") is
connected to the internal switch of the AR9330 platform.

Previously, this device had its own codepath in configurenetwork,
utilizing the ETHPORT variable, so the single physical port of the
switch could be connected to either the CLIENT or BATMAN vlan of the
SWITCHPORT.

When adding support for TWO_PORT devices, this codepath was accidentally
removed, so the LAN-Port was not configured anymore.

Configuring the internal switch is not necessary when only a single
physical port ist connected to it. Instead, leave the switch
unconfigured, so it behaves like an unmanaged vlan-transparent switch.

As we support TWO_PORT devices now, utilize the TWO_PORT codepath
(instead of the ONE_PORT codepath, which would be equivalent to the old
behaviour) to make both ports configureable. To retain the previously
configured mode of the LAN-Port, migrate ETHPORT to LAN1MODE before
executing configurenetwork.

With the recent rework of the network configuration, any existing

Fabian Bläse 1c3328e64a Remove static configuration from dynamic script
Most of the configuration done in configurenetwork is static and does
not change after the first boot. Move this static configuration into a
uci-defaults script, which is only executed on first boot.

Configuration which might be changed at runtime (e.g. port assignment),
is kept in the configurenetwork script.

To improve readability and speed, combine multiple uci commands into a
uci batch. Drop any existing network configuration before applying our
own configuration. This requires the network.globals section to be
created explicitly. Also, the fdff:: addresses, ETHMESHMAC and ROUTERMAC
can be set unconditionally, as the uci-defaults script is only executed
once. Other than that, the static configuration has not been altered.

Fabian Bläse 44c3328eb4 fff-network: add packet_steering option to enable RPS
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.

Enable this option agian to improve forwarding performance on routers
with multiple cpu cores.

Fabian Bläse 5d5eb29518 fff-network: Remove obsolete and unnecessary sysctls
Many of the set sysctls are either unnecessary, are already default in
the kernel or in OpenWrts defaults, or the reason for them being
explicitly set is unknown.

Remove all those sysctls from fff-network, as unfounded deviations from
default values will cause hard-to-debug problems in the future.

The original motivation for this patch is the netdev_max_backlog sysctl,
which was set to a very low value without any reason or comment.
This hurt forwarding performance on mt7621 with DSA significantly and
took quite a while to discover.

Fabian Bläse 3147a33c52 fff-network: Disable source address filtering
Source address filtering (RFC3704) can be used to mitigate source
address spoofing. However, strict mode only works when routes are
strictly symmetric. If routes are asymmetric, it can happen that
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.

Fabian Bläse 37695a1cfc fff-network: Add migration for Archer C7 WAN ports
With 8d66bdf the port configuration of TP-Link Archer C7 has been
changed to a single-interface configuration.

This had unforseen side effects on upgraded devices. Because WANDEV
is evaluated from the updated network.* file, the port configuration
of the switch is evaluated from the update-safe network.config, which
is now incompatible with the updated interface configuration.

Therefore, a migration script has to be added, which updates the port
configuration in network.config to the new single-interface network
configuration.

Adrian Schmutzler 24be8ecdda fff-network: fix unintended wan=eth1 for two-port devices
For historic reasons, the wan interface is set to eth1 as default
value. When updating the config for one-port devices in
configurenetwork, the same value is put there again if the mode
is switched to something != WAN, instead of just removing the
value.

While ifname actually is a mandatory value, this has been handled
inconsistently in the past, where ethmesh ifname was deleted, and
wan ifname was just changed back to eth1, when assigning the
actually relevant eth0 to a different task.

This concept was set up with a one-port device in mind, i.e. a
device where there is no eth1. However, this very setup routine
got applied to the Nanostation M as well (which is treated as
as one-port), where we suddenly have two interfaces and the eth1
exists.
So, while the user assumes it's unconfigured, the second port
actually becomes set up as WAN if the first one is != WAN.
If connected to a second device with CLIENT (=default) to provide
PoE there, this will create a loop.

So, finally, in order to somehow fix this mess, this patch just
changes the hardcoded "eth1" to "eth2". While this is no proper
fix, it perpetuates the original idea of keeping wan set to
something, but nothing which actually exists. However, there are
no sideeffects and we keep this minimal-invasive.

Fabian Bläse b5563caa23 fff-network: Improve IPv6 WAN connectivity
Until now, IPv6 connectivity was only ensured by some custom sysctls.
OpenWrt has a proper way of enabling IPv6 client (SLAAC, as well as DHCPv6)
for an interface. Switching to OpenWrt's way of configuring client addresses
for an interface might also make configuration more reliable, as the appropriate
sysctls are now set by netifd. Especially OnePort and TwoPort devices will
benefit from this change, as IPv6 auto configuration does not have to be manually
enabled and disabled for a physical interface, but rather is set as an option for
our logical wan interface.

At the same time this change enables DHCPv6 client support for WAN.

Tim Niemeyer b6c7acd704 nodewatcher: split into nodewatcher.d scripts for individual task
This splits up the data extraction/assembly of the nodewatcher
script into several parts and distributes them across packages, so
that each nodewatcher.d subscript is located in the package providing
the relevant functionality. This allows to extend the nodewatcher data
by enabling/disabling packages.
This scheme is not perfectly fulfilled for fff-network vs. fff-wireless,
as data cannot uniquely assigned there and the XML syntax does not allow
separation anyway.

In general, this moves code without applying code improvements, yielding
at an easy comparison of moved fragments. However, the following changes
were done to improve experience:

- The function writing debug output has been renamed from "err" to "debug"
- Since we catch the stdout of the nodewatcher.d functions anyway,
  those scripts were adjusted to echo output directly instead of first
  writing it into a variable and then outputting it at the end.
- The uci config has been kept, but initialization for the network part
  has been moved to the fff-network package.
- Space indent has been changed to tab, which is more common in the
  firmware and requires less space.
- Remove support for nodewatcher run without uci config. Script-based
  nodewatcher on other platforms will have altered code anyway, and
  splitting it up will prevent effective use as a blueprint for those
  cases. After this change, nodewatcher in firmware is supposed to be
  used only for this firmware.

Note that since the nodewatcher.d scripts are evaluated by using their
echo output, having a function created uncaught output to stdout there
will corrupt the XML.
