    net: Convert protocol error handlers from void to int · 32bbd879
    Stefano Brivio authored
    We'll need this to handle ICMP errors for tunnels without a sending socket
    (i.e. FoU and GUE). There, we might have to look up different types of IP
    tunnels, registered as network protocols, before we get a match, so we
    want this for the error handlers of IPPROTO_IPIP and IPPROTO_IPV6 in both
    inet_protos and inet6_protos. These error codes will be used in the next
    For consistency, return sensible error codes in protocol error handlers
    whenever handlers can't handle errors because, even if valid, they don't
    match a protocol or any of its states.
    This has no effect on existing error handling paths.
