This bug affects BPF helper bpf_l4_csum_replace and IPv6 ILA in adj-transport mode. In those cases, inet_proto_csum_replace_by_diff updates the L4 checksum field after an IPv6 address change. These two changes cancel each other in terms of checksum, so skb->csum shouldn't be updated. v2: https://lore.kernel.org/aCz84JU60wd8etiT@mail.gmail.com ==================== Link: https://patch.msgid.link/cover.1748509484.git.paul.chaignon@gmail.com Signed-off-by: Jakub Kicinski --- 558428921eddbd5083fe8116e31b8af460712f44
