With the recent changes to confd to support: hostname format specifiers,
$factory$ default keyword for password, and on-the-fly generation of the
NETCONF SSH host keys, the system no longer depend on the very intricate
confd gen-* scripts to create factory-config and failure-config.
This patch set adds support for detecting and installing product/vendor
specific static factory-config and failure-config files. See the confd
README for details.
To facilitate generation, e.g., of the NETCONF SSH host keys, the confd
daemon must be running when bootstrapping the first startup-config from
eithe generated or static factory-config. This is why the bootstrap and
load helper scripts have been changed.

This patch adds support for an empty "genkey" pair in the keystore for
the NETCONF hostkeys. Primarily intended for static factory-config.
When a configuration is loaded and confd detects a missing public or
private key in the "genkey" asymmetric key, it loads generated keys
from disk and store in the running datastore.

Since a user has access to the shell in developer mode, we might as
well allow booting through the standard boot scripts as well. This
means that a product with a bootloader only accepting images signed by
Company A can now be configured to netboot a regular developer image
without any special user interaction.
If we receive an option 67 (bootfile) matching http://IP/rootfs.itb,
use U-Boot's wget implementation to download the file. The web server
must listen on port 80. tftp:// is also supported.
Without a protocol prefix, assume that the bootfile should be fetched
using TFTP from ${serverip}.
Generate a boot menu, accessible with C-c during a short window, where
a user can interactively select a custom boot source and/or trigger a
factory reset of the device.
With this in place, we should always be able to unbrick a device, as
the image can be fed over the network, and local data can be ignored
by opting in to a factory reset.
By default, Linux will map an IP packet's TOS field into skb->priority
when acting as a router. Unfortunately this is only globally
configurable (per network namespace), which leaves us with the
following dilemma:
If we keep reclassification enabled, then a setup like this...
vlan1 vlan2
\ /
br0
/ \
e1 e2
...would likely not work as expected because any priority information
from hardware, that might be mapped to skb->priority via vlan1's
ingress-qos-map, would then be replaced by the standard TOS-mapping on
the routing boundary.
On the other hand, if we disable reclassification, then we won't be
able to source priority information from the TOS field when no other
source is available, as is the case when the source interface is a
regular NIC.
Given that the primary use-case is to run on switchdev ports, we will
most likely always have priority information available from hardware,
which is why we opt to disable the reclassification.
If this ever becomes configurable per interface, then we could open up
the configuration to let users define the policy of which layer's
priority should take precedence.
Opportunistically look for interfaces with multiple transmit queues
and hardware support for the mqprio queuing discipline. For every
matching interface, set up mappings from kernel-internal packet
priorities, via traffic classes, to transmit queues such that as many
high priorities as possible are scheduled on separate queues.
This makes it easier to add more scripts without having to update the
finit config file, and it clarifies which of the scripts in
/libexec/infix only execute at boot.
This enables access to /restconf on port 443 over HTTP/1.1 and HTTP/2
via rousette when enabled.
Also, slight refactor to allow including /restconf and /netbrowse as
optional locations in the main servier directive.

When interface naming switched to use 1-based indices instead of
0-based, the topology generation was overlooked thus breaking tests
against a `make run` instance.

- Add sshd 'UsePAM yes'
- Buildroot automatically adds and enables:
- /etc/pam.d/ with authentication for login, sshd, and sudo
- PAM support in BusyBox login
Also, prepare for adding RADIUS authentication support to ietf-system
the only tricky part is testing against a RADIUS server.

Assume that the caller always want to create a new partition table,
even in scenarios where one already exists. This allows devices to be
reprovisioned with a newer image, for example.

This fixes a serious security regression introduced late in the v24.04
release cycle. The root cause is the placement of the shadow file in
the rootfs overlay, which causes any changes made by the Buildroot
setting BR2_TARGET_ENABLE_ROOT_LOGIN to be discarded/overwritten just
before creating the squashfs image.
The fix in this commit relocates all files from b4eb450 to the skeleton
in Infix, package/skeleton-init-finit/skeleton/etc, which is one of the
first packages to be installed when starting a build.

The base mac address is used by bridges in Infix. This patch adds
support for extracting a base mac from the first interface "- 1",
e.g., if the mac address of e1 is 08:00:20:00:00:01, the base mac
will be 08:00:20:00:00:00.
This works with the Infamy test framework (Qeneth) and also with
the qemu script, included in this patch.

Today, only one certificate is shipped with infix, it is
selectable in menuconfig. It is also possible to add extra
certificates, useful when using infix as a submodule.
Even though dnsmasq only listened to requests from 127.0.0.1, port 53
was visible using nmap. We only use dnsmasq as a local resolver, so
we can safely change the config to bind to loopback instead, and at
the same time get less noise from nmap scans.
