Unless of course you wired up the OpenEnclave infrastructure to use the new VDSO and exception handling, as that would be a significant test, is that the case? Getting a real live enclave loaded and initialized in memory is essentially a contract with the enclave ELF parser and metadata interpreter that the runtime implements. There is nothing subtle about whether or not that is working correctly. The acid test after that is the enclave entry and exit handling which is ultimately a function of the exception handling. > Thanks, > Jordan Have a good remainder of the week.
