  "message": "ipv4: Fix ip_skb_dst_mtu to use the sk passed by ip_finish_output\n\nip_skb_dst_mtu uses skb-\u003esk, assuming it is an AF_INET socket (e.g. it\ncalls ip_sk_use_pmtu which casts sk as an inet_sk).\n\nHowever, in the case of UDP tunneling, the skb-\u003esk is not necessarily an\ninet socket (could be AF_PACKET socket, or AF_UNSPEC if arriving from\ntun/tap).\n\nOTOH, the sk passed as an argument throughout IP stack\u0027s output path is\nthe one which is of PMTU interest:\n - In case of local sockets, sk is same as skb-\u003esk;\n - In case of a udp tunnel, sk is the tunneling socket.\n\nFix, by passing ip_finish_output\u0027s sk to ip_skb_dst_mtu.\nThis augments 7026b1ddb6 \u0027netfilter: Pass socket pointer down through okfn().\u0027\n\nSigned-off-by: Shmulik Ladkani \u003cshmulik.ladkani@gmail.com\u003e\nReviewed-by: Hannes Frederic Sowa \u003channes@stressinduktion.org\u003e\nSigned-off-by: David S.
