Package: ferm Version: 2.4-1 Severity: normal Dear Maintainer,
1. With ebtables set to ebtables-nft (via alternatives): # cat /etc/ferm/printer.ferm @def $PrinterMAC = MAC; domain eb table broute chain BROUTING { daddr $PrinterMAC { DROP; } } # ferm /etc/ferm/printer.ferm Policy ACCEPT not allowed for user defined chains. Cannot rollback domain 'eb' because there is no ebtables-restore 2. With iptables set to iptables-nft (via alternatives) I've discovered NULL pointer dereference: https://bugzilla.kernel.org/show_bug.cgi?id=203681 (Yes, this is not a ferm issue) The question is: should ferm call *-legacy tools directly regardless alternative settings?
