Remote-attestation example is non-functional #44

Closed ahawad closed 8 years ago

ahawad commented 8 years ago

I have tried running the provided remote-attestation example, but it doesn't proceed to success; in fact, it seems that all three enclave programs "hang" after the call to malloc in the sgx-remote-attestation library.

Removing the call to malloc and replacing the dynamic arrays with static ones leads to progress. However, the attestation fails providing the error "Mac mismatch" .

When I tried to use printf to see what the values are of the calculated and provided MACs, garbage is output to the terminal. I am not entirely sure where things are going wrong, to be honest. Do you guys have any information on this issue/am I perhaps doing something wrong?

In case it matters I am running openSGX in kubuntu and compiled it as per the tutorial file.

I discovered my setjmp missing problem disappears if I revert to commit 6cc1fe695b61bd34eed199402b8ea575a6fe49ed. I suggest you try this commit and see what happens.

Reverting to that commit has indeed fixed the issue thanks for the suggestion.
