YiFei Zhu	b8bff6f890	selftests/bpf: Test bpf_{get,set}_retval behavior with cgroup/sockopt The tests checks how different ways of interacting with the helpers (getting retval, setting EUNATCH, EISCONN, and legacy reject returning 0 without setting retval), produce different results in both the setsockopt syscall and the retval returned by the helper. A few more tests verify the interaction between the retval of the helper and the retval in getsockopt context.

selftests/bpf: Test bpf_{get,set}_retval behavior with cgroup/sockopt

The tests checks how different ways of interacting with the helpers
(getting retval, setting EUNATCH, EISCONN, and legacy reject
returning 0 without setting retval), produce different results in
both the setsockopt syscall and the retval returned by the helper.
A few more tests verify the interaction between the retval of the
helper and the retval in getsockopt context.
