[Nicolas Dichtel]

Hi Ubuntu kernel team,

please, could you consider to backport the linux upstream commit ccd27f05ae7b
("ipv6: fix 'disable_policy' for fwd packets"):

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ccd27f05ae7b

It will be included in the next linux release (v5.14). The bug exists since
linux v4.12.

Here is the launchpad entry:

Thank you,
Nicolas
