Joachim Wiberg 6752ff4d2f cli: regression in ospf show commands
With the recent changes in Infix v24.08 to tighten up permissions, a
regression in the 'show ospf' family of commands was introduced.

This patch adds a 'doas' prefix to all vtysh commands.  The 'doas' tool
wraps sudo in a way such than unauthorized users do not get a sudo error
thrown as result.

A better fix might be to either include all admin group users also in
the UNIX group 'frrvty', or even better, change the default group of
vtysh to 'wheel'.  Affected files are /etc/frr/vtysh.conf and all
/run/frr/*.vty sockets, the latter are created at runtime by zebra,
ospfd, etc.  This require modifying the buildroot/package/frr/frr.mk
file, which unfortunately have the group hard coded.

    admin@R2:~$ ls -l /etc/frr/vtysh.conf
    -rw-r-----    1 frr      frrvty    32 Sep  3 05:27 /etc/frr/vtysh.conf

    admin@R2:~$ ls -l /run/frr/*.vty
    srwxrwx---    1 frr      frrvty     0 Sep  5 04:37 /run/frr/ospfd.vty
    srwxrwx---    1 frr      frrvty     0 Sep  5 04:37 /run/frr/zebra.vty

Joachim Wiberg 8a09b3e22c confd: fix audit logs using proper facility
The LOG_SECURITY facility was set wrong (1 << 13) instead of (13 << 3), see
https://github.com/kernelkit/sysklogd/blob/0fc6656/src/syslog.h#L120 for
details.  This caused all audit log messages to be logged in LOG_USER.

Also, rename LOG_SECURITY -> LOG_AUDIT and log macro SECURITY() -> AUDIT()
to match RFC5424 terminology.

Similar fix to sysrepo, LOG_AUDIT facility instead of daemon + WARNING.
Additionally, drop the leading [severity] prefix to sysrepo logs.  Only
needed when logging to stdout.

Joachim Wiberg fb00719069 package/klish: bump for droprivs refactor of script plugin
As of KernelKit Klish @ 710a631 the script plugin has been refactored to
run all commands as the logged in user instead of as root.  The default
admin user is member of the wheel group, which allows access to sysrepo
and sudo access to containers thanks to NOPASSWD rights.

The doas script is a dummy wrapper to silence 'sudo -n' output for users
without any privileges.

As of this commit, unprivileged users can no longer copy, show, or in
any other way manipulate the system configuraiton.

Joachim Wiberg 90f818437a confd: refactor ietf-syslog callbacks for log-file and remote
This refactor changes the callback subscription for log-file and remote
log actions to ensure they are called for *all* changes.  Even changes
to deeply nested sub-trees like file-rotation when no other changes are
made.  The previous attempt failed to address that.

The refactored callbacks replace sr_get_changes() with srx_get_changes()
for better control over what they iterate over.  The callbacks always
regenerate the syslogd *.conf file snippets for each log action, so
there is no need for the overly granular sr_get_changes(), ever.

are used when per-file rotation is not configured.  The defaults chosen
match previously decided defaults for Infix: 1M:10, i.e., rotate every

The standard model includes a default value of 1 for the number of files
kept, which is removed (deviated).  There is also a unit specified for
max-file-size, 'megabytes', replaced with 'kilobytes' in this change.
On smaller embedded systems, smaller sizes may be required.

Currently, it's not possible to run infix tests from an external
project (based on infix) due to an incompatibility between the
configuration used in the tests (the default configuration
within the image generated by the external project) and the infix
base configuration expected by the test cases. Therefore, a simple
configuration specifically for testing purposes needs to be generated
within an image. This test-config should always be generated
but only loaded when the device is in test mode.

Joachim WibergandTobias Waldekranz 890d812b69 board/common: allow device specific compat strings for .pkg files
This patch allows us to define the rauc manifest compatibility string with
menuconfig.  The INFIX_IMAGE_ID is a direct replacement for the previously
composed "infix-$ARCH" in mkrauc.sh.

For example, the compatibility string "infix-aarch64" is replaced for the
NanoPi R2S with "infix-r2s" to ensure users get a proper warning if they
try upgrading to an image that maybe boots, but is not likely to work.

The CLI upgrade command gets a 'force' flag to override the compat string.
