REJECT iptables rule not applying after 6.12.1 => 6.12.4 upgrade

[danog]

An iptables setup containing a iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited doesn't block incoming connections on 6.12.4, on an Ubuntu system running the cachyos kernel.

Everything worked correctly on 6.12.1, and testing on a dev cachyos machine on 6.12.5 also seems to work fine: will attempt to test 6.12.5 on ubuntu, opening this issue just to track the existence of the problem at least on 6.12.4.

Since this was likely then an upstream issue, I think we can close this, since its fixed .5. :)
