These commits added second dif to raw, inet{6,}, udp, multicast sockets. The change is not a fix but a feature - significant change, therefore I understand if you're aginast backporting it. My motivation is to get backported to LTS 4.9 these fixes from v5.17 (which has been backported to all newer stable/LTS trees): 2afc3b5a31f9 ("ping: fix the sk_bound_dev_if match in ping_lookup") 35a79e64de29 ("ping: fix the dif and sdif check in ping_lookup") cd33bdcbead8 ("ping: remove pr_err from ping_lookup") which fix small issue with IPv6 in ICMP datagram socket ("ping" socket). These 3 commits depend on 9bcb5a572fd6, particularly on: 3fa6f616a7a4d ("net: ipv4: add second dif to inet socket lookups") 4297a0ef08572 ("net: ipv6: add second dif to inet6 socket lookups") Kind regards, Petr
