  - ipvs修正 saddr 引數 [1] 的 uninit-value 之 do_output_route4 syzbot 報告中 saddr 的 uninit-value。認可 4754957f04f5 (ipvs請勿針對通道使用隨機本機來源位址) 已暗示應忽略 saddr 的輸入值但程式碼仍在讀取該值這可能會阻止 連線路由。透過變更 ret_saddr 的引數來修正此問題。 [1] 錯誤KMSANdo_output_route4+0x42c/0x4d0 net/netfilter/ipvs/ip_vs_xmit.c:147 do_output_route4+0x42c/0x4d0 net/netfilter/ipvs/ip_vs_xmit.c:147 中的 uninit-value __ip_vs_get_out_rt+0x403/0x21d0 net/ netfilter/ipvs/ip_vs_xmit.c:330 ip_vs_tunnel_xmit+0x205/0x2380 net/netfilter/ipvs/ip_vs_xmit.c:1136 ip_vs_in_hook+0x1aa5/0x35b0 net/netfilter/ipvs/ip_vs_core.c:2063 nf_hook_entry_hookfninclude/////linux 154 [內嵌] nf_hook_slow+0xf7/0x400 net/netfilter/core.c:626 nf_hook include/linux/netfilter.h:269 [內嵌]
