Make `bpf link show` aware of new link type, that is links attached to
netns. When listing netns-attached links, display netns inode number as its
identifier and link attach type.
Sample session:
# readlink /proc/self/ns/net
net:[4026532251]
# bpftool prog show
357: flow_dissector tag a04f5eef06a7f555 gpl
loaded_at 2020-05-30T16:53:51+0200 uid 0
xlated 16B jited 37B memlock 4096B
358: flow_dissector tag a04f5eef06a7f555 gpl
loaded_at 2020-05-30T16:53:51+0200 uid 0
xlated 16B jited 37B memlock 4096B
# bpftool link show
108: netns prog 357
netns_ino 4026532251 attach_type flow_dissector
# bpftool link -jp show
[{
"id": 108,
"type": "netns",
"prog_id": 357,
"netns_ino": 4026532251,
"attach_type": "flow_dissector"
}
]
(... after netns is gone ...)
# bpftool link show
108: netns prog 357
netns_ino 0 attach_type flow_dissector
# bpftool link -jp show
[{
"id": 108,
"type": "netns",
"prog_id": 357,
"netns_ino": 0,
"attach_type": "flow_dissector"
}
]
