bpf: add bpf_clone_redirect to bpf_helper_changes_pkt_data
[ Upstream commit 41703a731066fde79c3e5ccf3391cf77a98aeda5 ]
The bpf_clone_redirect() still needs to be listed in
bpf_helper_changes_pkt_data() since we call into
bpf_try_make_head_writable() from there, thus we need
to invalidate prior pkt regs as well.
Fixes: 36bbef52c7eb ("bpf: direct packet write and access for helpers for clsact progs")
