Hi, I use iproute-5.10 with kernel-5.10.6, I found that ip-nexthop does not support flush by id, is it by design?
Reproduce steps: # ip netns add me # ip -netns me addr add 127.0.0.1/8 dev lo # ip -netns me link set lo up # ip -netns me nexthop add id 105 blackhole proto 99 # ip -netns me nexthop flush id 105 id 105 blackhole proto 99 # ip -netns me nexthop ls id 105 blackhole proto 99 while use flush without any args, flush will success. # ip -netns me nexthop flush Flushed 1 nexthops I find the function ipnh_list_flush implemented in ipnexthop.c: else if (!strcmp(*argv, "id")) { __u32 id; NEXT_ARG(); if (get_unsigned(&id, *argv, 0)) invarg("invalid id value", *argv); return ipnh_get_id(id); } When args is “id”, just return the related info of “id”, so I want to known is it by design ?
