However, there are existing enclaves (e.g. those built with current Intel SGX SDK libraries) relying on the untrusted stack for passing parameters to untrusted functions (aka. o-calls), which requires allocating space on the untrusted stack by enclaves. And given its simplicity and convenience, it could be desired by future SGX applications as well. This patchset introduces a new ABI for __vdso_sgx_enter_enclave() to anchor its stack frame on %rbp (instead of %rsp), so as to allow enclaves to "push" onto the untrusted stack by decrementing the untrusted %rsp. Additionally, this new __vdso_sgx_enter_enclave() will take one more parameter - a callback function, to be invoked upon all enclave exits (both AEX and normal exits). The callback function will be given the value of %rsp left off by the enclave, so that data "pushed" by the enclave (if any) could be addressed/accessed. Please note that the callback function is optional, and if not supplied (i.e. null), __vdso_sgx_enter_enclave() will just return (i.e. behave the same as the current implementation) after the enclave exits (or AEX due to exceptions). The SGX selftest is augmented to test out the new callback interface, and to serve as a simple example to showcase how to use the callback interface in practice.
