Hou Tao	e3dd408285	selftests/bpf: Test outer map update operations in syscall program ... Syscall program is running with rcu_read_lock_trace being held, so if bpf_map_update_elem() or bpf_map_delete_elem() invokes synchronize_rcu_tasks_trace() when operating on an outer map, there will be dead-lock, so add a test to guarantee that it is dead-lock free.

Delyan Kratunov	3931618378	selftests/bpf: Migrate from bpf_prog_test_run_xattr ... bpf_prog_test_run_xattr is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK_ATTR so replace usages with ASSERT_* calls. Also, prog_run_xattr is now prog_run_opts.

Alexei Starovoitov	00899e7e8d	selftests/bpf: Test for syscall program type ... bpf_prog_type_syscall is a program that creates a bpf map, updates it, and loads another bpf program using bpf_sys_bpf() helper.
