bpf-workshp

bpf-workshop is just the simplest skeleton that helps developers to write their bpf codes. It only contains the example.bpf.c.

How to Build

$ make

Then example.bpf.c will be compiled into example.bpf.o.

You can use make clean to delete *.bpf.o.

libbpf and vmlinux.h

• include/bpf

  • From libbpf v0.6.1 release version
  • Build from the following commands:

    $ cd src/
    $ mkdir build root
    $ BUILD_STATIC_ONLY=y OBJDIR=build DESTDIR=root make install

    Then copy root/usr/include/bpf directory.

• include/vmlinux.h: It's the symbol link of bpf/include/vmlinux_510.h and dump from linux 5.10 kernel:

  $ bpftool btf dump file /sys/kernel/btf/vmlinux format c

Code Style

• Use .clang-format to format C codes: The clang format is from linux kernel(linux-5.13.12) and use spaces instead of tab.
