Extend the enclave to have two operations: ENCL_OP_PUT and ENCL_OP_GET. ENCL_OP_PUT stores value inside the enclave address space and ENCL_OP_GET reads it. The internal buffer can be later extended to be variable size, and allow reclaimer tests.

Test output before applying the series: TAP version 13 1..1 # selftests: sgx: test_sgx # Unable to open /dev/sgx_enclave: No such file or directory # 1..0 # SKIP cannot load enclaves ok 1 selftests: sgx: test_sgx # SKIP Test output after applying second patch selftests/sgx: Migrate to kselftest harness Output changes to the following. It doesn't look like the second patch adds any new tests. What is the point in running the tests that fail if /dev/sgx_enclave is missing. Unfortunately this series doesn't have a cover letter that explains what this series is doing. I don't like the fact that the test output and behavior changes when migrating the test to kselftest harness. Shouldn't the output stay the same as in skip the tests if /dev/sgx_enclave fails.
