Re: [PATCH bpf-next v2 2/2] selftests/bpf: add tests for attaching invalid fd

Kohei Enju enjuk@amazon.com writes:

Add test cases for situations where adding the following types of file descriptors to a cpumap entry should fail:

• Non-BPF file descriptor (expect -EINVAL)
• Nonexistent file descriptor (expect -EBADF)

Also tighten the assertion for the expected error when adding a non-BPF_XDP_CPUMAP program to a cpumap entry.
