Subject: [PATCH v4 bpf-next 0/4] bpftool: Add struct_ops support
Date: Wed, 18 Mar 2020 10:16:31 -0700 [thread overview]
Message-ID: <20200318171631.128566-1-kafai@fb.com> (raw)
This set adds "struct_ops" support to bpftool.
The first two patches improve the btf_dumper in bpftool.
Patch 1: print the enum's name (if it is found) instead of the
enum's value.
Patch 2: print a char[] as a string if all characters are printable.
"struct_ops" stores the prog_id in a func ptr.
Instead of printing a prog_id,
patch 3 adds an option to btf_dumper to allow a func ptr's value
to be printed with the full func_proto info and the prog_name.
Patch 4 implements the "struct_ops" bpftool command.
v4:
- Return -EINVAL in patch 1 (Andrii)
v3:
- Check for "case 1:" in patch 1 (Andrii)
v2:
- Typo fixes in comment and doc in patch 4 (Quentin)
- Link to a few other man pages in doc in patch 4 (Quentin)
- Alphabet ordering in include files in patch 4 (Quentin)
- Use GET_ARG() in patch 4 (Quentin)
Martin KaFai Lau (4):
bpftool: Print the enum's name instead of value
bpftool: Print as a string for char array
bpftool: Translate prog_id to its bpf prog_name
bpftool: Add struct_ops support
