With different cgroups, the script starts one or multiple concurrent SGX selftests (test_sgx), each to run the unclobbered_vdso_oversubscribed test case, which loads an enclave of EPC size equal to the EPC capacity available on the platform. The script checks results against the expectation set for each cgroup and reports success or failure. The script creates 3 different cgroups at the beginning with following expectations: 1) small - intentionally small enough to fail the test loading an enclave of size equal to the capacity. 2) large - large enough to run up to 4 concurrent tests but fail some if more than 4 concurrent tests are run. The script starts 4 expecting at least one test to pass, and then starts 5 expecting at least one test to fail. 3) larger - limit is the same as the capacity, large enough to run lots of concurrent tests. The script starts 8 of them and expects all pass. Then it reruns the same test with one process randomly killed and usage checked to be zero after all processes exit. The script also includes a test with low mem_cg limit and large sgx_epc limit to verify that the RAM used for per-cgroup reclamation is charged to a proper mem_cg. For this test, it turns off swapping before start, and turns swapping back on afterwards. Add README to document how to run the tests.
