A very quiet week, here are the details of the few notable changes…

rdisc

On Ubuntu Noble there is now a networkd-dispatcher hook which will restart rdisc whenever the network configuration is changed. This should help to ensure the default route does not disappear.

PHP

The lcfg/options/php.h and lcfg/options/apacheconf-php8.h headers now support PHP 8.3 for Ubuntu Noble.

Software

LCFG_OPTIONS_CONNTRACKD – Provides the conntrackd connection tracking daemon software.

New IPTABLES Convenience Macros

The lcfg/options/iptables.h header gained four new macros to make it easier to maintain a local firewall configuration – IPTABLES_CHAIN_CONCAT(chain,rule,"comment") and a IPTABLES_CHAIN_PRECONCAT() partner, IPTABLES_ACCEPT_TCP(port) and IPTABLES_ACCEPT_UDP(port). They are functionally identical to those with the same names in Physics’ phys/options/super-simple-firewall.h, Biology’s biolsci/options/iptables-jupyterhub.h and GeoSciences’ geos/options/iptables.h so these won’t need to be changed, but no longer need to be defined locally.

These will be used to develop a simple local default deny incoming firewall in a new header inspired by mdp/options/iptables.h in the coming releases.
