Stanislav Fomichev	e01b4a72f1	selftests/bpf: Correctly handle optlen > 4096 ... Even though it's not relevant in selftests, the people might still copy-paste from them. So let's take care of optlen > 4096 cases explicitly.

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.
