Manu Bretelle d55dfe587b bpftool: Remove BPF_OBJ_NAME_LEN restriction when looking up bpf program by name ... bpftool was limiting the length of names to BPF_OBJ_NAME_LEN in prog_parse fds. Since commit b662000aff ("bpftool: Adding support for BTF program names") we can get the full program name from BTF. This patch removes the restriction of name length when running `bpftool prog show name ${name}`. Test: Tested against some internal program names that were longer than `BPF_OBJ_NAME_LEN`, here a redacted example of what was ran to test. # previous behaviour $ sudo bpftool prog show name some_long_program_name Error: can't parse name # with the patch $ sudo ./bpftool prog show name some_long_program_name 123456789: tracing name some_long_program_name tag taghexa gpl .... ... ... ... # too long sudo ./bpftool prog show name $(python3 -c 'print("A"*128)') Error: can't parse name # not too long but no match $ sudo ./bpftool prog show name $(python3 -c 'print("A"*127)') Signed-off-by: Manu Bretelle <chantr4@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Tested-by: Jiri Olsa <jolsa@kernel.org> Reviewed-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20220801132409.4147849-1-chantr4@gmail.com		2022-08-04 14:41:13 -07:00
