IP_ECN_decapsulate() and IP6_ECN_decapsulate() assume IP header is already pulled.
geneve does not ensure this yet.
Fixing this generically in IP_ECN_decapsulate() and IP6_ECN_decapsulate() is not possible, since callers pass a pointer that might be freed by pskb_may_pull()

I'll drop it thanks. Odd I lost the upstream git id on this patch, let me check what went wrong...
