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.
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.

- 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.

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.

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.

This commit adds an initial YANG model for Infix web services under the
infix-services.yang umbrella. For now the nginx server statements in
/etc/nginx/nginx.conf are always on, but the backend ttyd, and the
entire nginx server can be disabled.
The default in the YANG model for both is disabled, the factory-config
has been updated to enable these services by default.
The Web Console Interface mDNS service has been updated to advertise
on port 7681, which nginx is set to forward to ttyd.

With Classic builds out of the way we can move everything back to common
again to simplify and reduce our collective cognitive overhead a bit.

With the changes in 9847a8f we can keep the /etc/motd file with a proper
newline at EOF so that also Classic builds make sense.

Sending SIGTERM to conmon is not a safe shutdown of a podman container.
To handle gracefully handle shutdown, restarting and provide an orderly
start of dependencies, we use the Finit sysv trick via container script
wrapper to call 'podman stop foo'.
However, since podman does not support syslog as output for containers
we employ an old FIFO trick with another program, k8s-logger, to allow
logs to reach syslog. Please note that k8s-logger must have properly
started before we call `podman start` -- this makes us fully dependent
on the 'container' wrapper script. Hence the documentation update.

Install the sudo command, and let all members of the "wheel" group run
any command as the superuser.
This ensures that administrators have full access to the system,
primarily for troubleshooting, diagnostics, and remote scripting
purposes.
Move from everything in a single /etc/chrony.conf to a split up with
configuration and server snippets. The latter comes in the form of
configured (static) and DHCP client (dynamic) server setup.
To accomodate this new scheme we need to detect when serves are removed
from the configuration, so not only have the whole change_ntp() been
refactored, it has been extended with a new pass.

The bootstrap script gets feedback from gen-admin-auth, on error we no
longer bail out but instead log the error and continue booting. This
way a developer build with root login can diagnose the error.
When logging the error we also set /etc/issue, /etc/issue.net for local
and remote login services, as well as the dedicated /etc/banner used by
OpenSSH, to hold the error summary. So when attaching to the console
port, or attempting to log in remotely with SSH, the error is printed
to indicate the device is not healthy.
Finally, since factory-config may be missing we need to bootstrap the
sysrepo db with something else, and fortunately we will always have a
failure-config to fall back on.
