2020-09-28	selftest: bpf: Test copying a sockmap and sockhash	Lorenz Bauer	1	-5/+22
	Since we can now call map_update_elem(sockmap) from bpf_iter context it's possible to copy a sockmap or sockhash in the kernel. Add a selftest which exercises this.

2020-09-28	selftests: bpf: Remove shared header from sockmap iter test	Lorenz Bauer	1	-3/+2
	The shared header to define SOCKMAP_MAX_ENTRIES is a bit overkill. Dynamically allocate the sock_fd array based on bpf_map__max_entries instead.

2020-09-10	selftests: bpf: Test iterating a sockmap	Lorenz Bauer	1	-0/+43
	Add a test that exercises a basic sockmap / sockhash iteration. For now we simply count the number of elements seen. Once sockmap update from iterators works we can extend this to perform a full copy.
