dingelish commented on issue #195: Get SGX_ERROR_INVALID_PARAMETER when Calling sgx_get_quote()
URL: https://github.com/apache/incubator-teaclave-sgx-sdk/issues/195#issuecomment-574040669
 
 
   Please look closer into Intel's manual:
   https://download.01.org/intel-sgx/sgx-linux/2.7.1/docs/Intel_SGX_Developer_Reference_Linux_2.7.1_Open_Source.pdf
    sgx_get_quote is on page 163-165.
   
   at the bottom of page 165, intel writes clearly:
   > Library: Requirements - libsgx_epid.so or libsgx_uae_service_sim.so (simulation)
   
   these two requirements (two general linux shared object), as well as the name of "uae_service) both indicate that this function can only be called in the untrusted app. you cannot call it in the enclave.
   
   you can look into the mutual-ra enclave sample to see how to generate a quote:
