Marek Marczykowski-Górecki	57a3c2d67e	network: have safe fallback in case of qubes-firewall crash/error ... When qubes-firewall service is started, modify firewall to have "DROP" policy, so if something goes wrong, no data got leaked. But keep default action "ACCEPT" in case of legitimate service stop, or not starting it at all - because one may choose to not use this service at all. Achieve this by adding "DROP" rule at the end of QBS-FIREWALL chain and keep it there while qubes-firewall service is running. Fixes QubesOS/qubes-issues#3269	2017-11-20 01:56:14 +01:00
Marek Marczykowski-Górecki	ee0a292b21	network: rewrite qubes-firewall daemon ... This rewrite is mainly to adopt new interface for Qubes 4.x. Main changes: - change language from bash to python, introduce qubesagent python package - support both nftables (preferred) and iptables - new interface (https://qubes-os.org/doc/vm-interface/) - IPv6 support - unit tests included - nftables version support running along with other firewall loaded Fixes QubesOS/qubes-issues#1815 QubesOS/qubes-issues#718	2016-09-12 05:22:53 +02:00
Marek Marczykowski	f33d2e4f42	vm/iptables: block IPv6 traffic ... This isn't properly handled by Qubes VMs yet, so block it in all the VMs. Also restrict access to firewall config.	2012-09-25 16:14:06 +02:00
