Hi Ubuntu kernel team,

please, could you consider to backport the linux upstream commit 6f3f65d80dac
("net: bpf: Allow TC programs to call BPF_FUNC_skb_change_head"):

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6f3f65d80dac

It is included in v5.8 (the bug exists since v4.10).

Here is the launchpad entry:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896504


Thank you,
Nicolas
