[SRU][F][PATCH 0/1] tc/ebpf: unable to use BPF_FUNC_skb_change_head

[Ian May]

BugLink: https://bugs.launchpad.net/bugs/1896504

[Impact]

tc ebpf programs that uses BPF_FUNC_skb_change_head are rejected.

[FIX]

Clean cherry pick from the 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

[Test Case]

Create an ebpf program that uses this helper and load it with tc.

[Regression Potential]

This patch is enabling an additional feature of ebpf, the potential regressions should be low.
