This code path eventually calls fib_compute_spec_dst()\nwhich dereferences skb-\u003edev. An attempt was made to fix the NULL skb-\u003edev\ndereference in commit 0113d9c9d1cc (\"ipv4: fix null-deref in\nipv4_link_failure\"), but it only addressed the immediate dev_net(skb-\u003edev)\ndereference by using a fallback device. The fix was incomplete because\nfib_compute_spec_dst() later in the call chain still accesses skb-\u003edev\ndirectly, which remains NULL when IPVS calls dst_link_failure().\n\nThe crash occurs when:\n1. IPVS processes a packet in NAT mode with a misconfigured destination\n2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route\n3. The error path calls dst_link_failure(skb) with skb-\u003edev == NULL\n4. ipv4_link_failure() -\u003e ipv4_send_dest_unreach() -\u003e\n   __ip_options_compile() -\u003e fib_compute_spec_dst()\n5. fib_compute_spec_dst() dereferences NULL skb-\u003edev\n\nApply the same fix used for IPv6 in commit 326bf17ea5d4 (\"ipvs: fix\nipv6 route unreach panic\"): set skb-\u003edev from skb_dst(skb)-\u003edev before\ncalling dst_link_failure().\n\nKASAN: null-ptr-deref in range [0x0000000000000328-0x000000000000032f]\nCPU: 1 PID: 12732 Comm: syz.1.3469 Not tainted 6.6.114 #2\nRIP: 0010:__in_dev_get_rcu include/linux/inetdevice.h:233\nRIP: 0010:fib_compute_spec_dst+0x17a/0x9f0 net/ipv4/fib_frontend.c:285\nCall Trace:\n  \u003cTASK\u003e\n  spec_dst_fill net/ipv4/ip_options.c:232\n  spec_dst_fill net/ipv4/ip_options.c:229\n  __ip_options_compile+0x13a1/0x17d0 net/ipv4/ip_options.c:330\n  ipv4_send_dest_unreach net/ipv4/route.c:1252\n  ipv4_link_failure+0x702/0xb80 net/ipv4/route.c:1265\n  dst_link_failure include/net/dst.h:437\n  __ip_vs_get_out_rt+0x15fd/0x19e0 net/netfilter/ipvs/ip_vs_xmit.c:412\n  ip_vs_nat_xmit+0x1d8/0xc80 net/netfilter/ipvs/ip_vs_xmit.c:764",
