Added support to show filenames of pinned objects. For example: root@test# ./bpftool prog 3: tracepoint name tracepoint__irq tag f677a7dd722299a3 loaded_at Oct 26/11:39 uid 0 xlated 160B not jited memlock 4096B map_ids 4 pinned /sys/fs/bpf/softirq_prog 4: tracepoint name tracepoint__irq tag ea5dc530d00b92b6 loaded_at Oct 26/11:39 uid 0 xlated 392B not jited memlock 4096B map_ids 4,6 root@test# ./bpftool --json --pretty prog [{ "id": 3, "type": "tracepoint", "name": "tracepoint__irq", "tag": "f677a7dd722299a3", "loaded_at": "Oct 26/11:39", "uid": 0, "bytes_xlated": 160, "jited": false, "bytes_memlock": 4096, "map_ids": [4 ], "pinned": ["/sys/fs/bpf/softirq_prog" ] },{ "id": 4, "type": "tracepoint", "name": "tracepoint__irq", "tag": "ea5dc530d00b92b6", "loaded_at": "Oct 26/11:39", "uid": 0, "bytes_xlated": 392, "jited": false, "bytes_memlock": 4096, "map_ids": [4,6 ], "pinned": [] } ] root@test# ./bpftool map 4: hash name start flags 0x0 key 4B value 16B max_entries 10240 memlock 1003520B pinned /sys/fs/bpf/softirq_map1 5: hash name iptr flags 0x0 key 4B value 8B max_entries 10240 memlock 921600B root@test# ./bpftool --json --pretty map [{ "id": 4, "type": "hash", "name": "start", "flags": 0, "bytes_key": 4, "bytes_value": 16, "max_entries": 10240, "bytes_memlock": 1003520, "pinned": ["/sys/fs/bpf/softirq_map1" ] },{ "id": 5, "type": "hash", "name": "iptr", "flags": 0, "bytes_key": 4, "bytes_value": 8, "max_entries": 10240, "bytes_memlock": 921600, "pinned": [] } ] Signed-off-by: NPrashant Bhole <bhole_prashant_q7@lab.ntt.co.jp> Signed-off-by: NDavid S.
