Fabian Bläse 8ef6dba5a1 fff-babeld: Only select first list entry from router_ip
The router_ip option can be a list of multiple ip addresses. It is also
possible to specify a subnet using a CIDR mask.

Only a single ip is required for peering interfaces, so select only the
first list entry and remove the CIDR mask.

Johannes Kimmel feeead6c43 fff-firewall: remove obsolete rules
20-clamp-mss:

Clamping is done in other parts of the network and to a very low static
value. This rules is very likely doing nothing at the moment.

20-filter-ssh:

These rules make use of the conntrack module to ratelimit incoming
connections. Using conntrack comes with a performance penalty for all
traffic. As an alternative, dropbear could be run behind an inetd(-like)
service that does the ratelimit, should removing this rule result in an
actual attack vector.

Removing both rules would enable us to unload the conntrack module all
together, potentially improving overall performance.

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 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

the script is either killed by the user (after successful configuration)

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.

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.

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.

Adrian Schmutzler 1946aaca87 fff: create proper package variants instead of copying file
So far, we ensure the selection of a specific variant by copying
included Make files. This not only breaks if the packages are used
as a feed, but also is against the concept of how packages are used.

In this patch, the fff package is converted into a set of variants
that allow selection via a FFF_VARIANT variable that is exported by
buildscript. If no export happens, e.g. when using packages in a
feed, no package is selected.

Since the names fff-node and fff-layer3 are not available anymore,
the packages for the variants are called (though irrelevant for
the user):

  * fff-variant-layer3
  * fff-variant-node

The only drawback is that we now have to specify the list of
available variants in the buildscript. However, these values are
hardcoded in several other places as well, and the former code
based on file names was not really appealing anyway.

Christian Dresel da50954db7 fff-web: Make ssl menu modular
To add new menu items in other packages we need a modular construction:
- Simpel Babelweb
- Layer 3 configuration
and so on

Every menu item needs a file in /www/menu/ssl/ with the content

  link,name

  - link is the name of the html file without extension (.html)
  - name is the text of the link in the webui

While at it, rename "Password" menu item to German "Passwort".

Adrian Schmutzler 8fe7512ae5 ramips/mt76x8: Add support for TP-Link Archer C50 v4
Add support for the TP-Link Archer C50 v4, a low-cost mt7628-based
dual-band router.

Label MAC address is on ethernet and 2.4 GHz WiFi.

The v4 uses the same hardware as the v3 variant, but v4 includes
the newer split uboot.

ATTENTION:

Initial flashing of this device requires additional steps:

As all installation methods require an U-Boot to be integrated into the
image (and we do not ship one with the image) we are not able to create
an image in our build-process.

Download a TP-Link image from their Website and a FFF/OpenWRT sysupgrade
image for the device and build yourself a factory image like following:

TP-Link image:             tpl.bin
OpenWRT sysupgrade image:  owrt.bin

 > dd if=tpl.bin of=boot.bin bs=131584 count=1
 > cat owrt.bin >> boot.bin

This image can be used for Web-UI and recovery, but not TFTP.

Additional instruction can be found in the OpenWrt commit
01dcd574a248 ("ramips: add support for Archer C50 v4")

Fabian Bläse 52e15e072c fff-firewall: Remove ssh firewall on WAN interface
This firewall was introduced as a countermeasure for very slow routers
directly connected to the internet without any firewall.

Our routers have got quite a bit faster since then. Also, a setup like
this is highly uncommon, especially for slower routers.

Therefore this firewall rule is removed.

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.

The factory image needs to be uploaded via the OEM firmware GUI.

Notes:

The device is implemented as two-port in OpenWrt, i.e. it has
eth0/eth1 interfaces without switch setup. As our firmware currently
does not support that, this uses a switch setup with one port for
LAN.

This removes two useless cat as found by shellcheck:

               ^-- SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead.

While not functionally relevant in our case, note that

  cat <non-existant-file> | sha256sum

actually returns a hash code, while

  sha256sum <non-existant-file>

does not return anything on stdout.

Since we check the existance of $hoodfiletmp before calling sha256sum,
though, we always have a hash value for at least one file, so two empty
checksum won't happen at that point.
