Does this repo contains 192 programs you claimed in the paper?

elazarg commented 3 years ago

Yes. There are more sections than that, but

some sections hold the same program
some programs use features that were unsupported at the time of publication
some files are new

The ebpf-verifier repo has a link to the version from the paper, in the README.md file, along with instructions how to reproduce the results.

hckuo2 commented 3 years ago

I only see 102 .o files in the repo. Could you point me to the rest?

Thanks

elazarg commented 3 years ago

Most files contain more than one section, the sections are the programs. You can list them using ./check -l PROGRAM. For example:

$ ./check -l ebpf-samples/cilium/bpf_lxc.o
2/1 2/3 2/5 2/4 2/10 2/7 2/6 from-container 2/12 2/11 1/0x1010 2/8 2/9

Alternatively, you can use llvm-objdump. For example llvm-objdump -d ebpf-samples/cilium/bpf_lxc.o prints disassembly of all the programs in the file.

Also, see here a complete list of the programs ( = sections in the .o files) we can and cannot verify.

hckuo2 commented 3 years ago

Is each section loaded as a BPF program in the kernel?

elazarg commented 3 years ago

Yes.

hckuo2 commented 3 years ago

Thank you very much! I see 366 programs now.
