Public bug reported: [Impact]
The ipv6 sysctl entry 'disable_policy' has effect for local packets only (while the ipv4 version is for all packets coming from the specified interface). This is fixed upstream with commit ccd27f05ae7b ("ipv6: fix 'disable_policy' for fwd packets"). https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ccd27f05ae7b [Test Case] Enable 'disable_policy' for an interface: sysctl -w net.ipv6.conf.eth0.disable_policy=1 Add an ipsec policy: ip xfrm policy add src fd00:100::/64 dst fd00:200::/64 dir out tmpl src fd00:125::1 dst fd00:125::2 proto esp mode tunnel Try a ping from subnet fd00:100::/64 to subnet fd00:200::/64.
