[SGX] Use Fortanix EDP #2885

nhynes · 2019-03-24T08:03:55Z

Depends on #2616

TODO:

This currently breaks direct use of python, but greatly simplifies the use of TVM in SGX. Future improvements include:

enclave as TVM RPC server
calling enclaves from Python using custom enclave runner

Notes:

Thanks to @paddyhoran for adding docs fixes in #4114

tqchen · 2019-03-24T17:54:29Z

This seems to be a significant change, perhaps it would be better to open a RFC to elaborate the reasons behind the change. Specifically:

What is the reason to move away from the original rust SGX SDK, benefits
Dependency and license issue(The Fortanix one is MPL while the original one is BSD)
- This might affect whether a user will want to use the tool
Would the original C++ example makes it easier to port to other enclave based runtime?

I am not expert but my observation is that our current way of SGX is "closer to the metal", which brings a bit more boilerplate code. This may or may not be a bad thing depending on how stable the code is and how can we evolve.

ping @nhynes see if you would like to push it through

nhynes · 2019-07-23T15:41:21Z

Yes, absolutely! I'll give it a go this weekend.

kaimast · 2019-09-22T04:17:23Z

Whats the status of this branch? Any chance it's being merged soon?

nhynes · 2019-09-22T23:15:59Z

Any chance it's being merged soon?

Sure! I didn't know if anyone but me was keen on using it, so I've been keeping it WIP as the EDP and Rust evolve. I'll start tidying it up now for a merge hopefully this week.

Mind if I ask what you're working on?

kaimast · 2019-09-23T04:12:29Z

Thanks for updating the branch.

Are you able to build this with the most recent rust nightly? I'm still running into this strange compile error. https://discuss.tvm.ai/t/linker-errors-when-compiling-rust-bindings/3712

nhynes · 2019-09-23T05:02:57Z

strange compile error

For some reason the frontend was being compiled as a dylib. This PR fixes that.

Although, you shouldn't need the frontend if you're just trying to use the Rust runtime.

tqchen · 2019-10-10T20:10:52Z

gentle ping :)

nhynes · 2019-10-10T20:26:40Z

this was ready two weeks ago but nobody reviewed it 🤷‍♂

tqchen · 2019-10-10T21:05:02Z

Aaha, my bad, would be great if we could bring in more reviewers. @kaimast @jroesch @jethrogb can you review?

did we re-enabled the rust test in CI already?

kaimast · 2019-10-10T23:45:34Z

I still get the build error mentioned above if I compile on the latest rust nightly even if I use the default toolchain.

nhynes · 2019-10-12T18:08:42Z

build error mentioned above if I compile on the latest rust nightly

🤦‍♂ I had a3c7f9c in a local branch

Should be fixed now. Also CI is re-enabled (@tqchen)

jethrogb · 2019-10-12T19:59:50Z

Latest Rust nightly broke a couple of targets (including SGX), so you have to use 2019-10-11 instead until fixed. See rust-lang/rust#65335

kaimast · 2019-10-12T20:38:54Z

Thanks! I think my issue was related to the tvm_runtime being linked to CUDA. When I disable CUDA in the C library the rust bindings from this branch compile fine.

kaimast · 2019-10-12T21:02:59Z

Could we add a short readme for the rust bindings? In particular which configurations are compatible with the bindings. It seems like CUDA does not work right now but you need to enable LLVM and have the python bindings installed.

Also the tests currently fail for me. I get this error

sorry that that i lost track of this thread, @nhynes can you rebase and let us merge it in :)?

ehsanmok · 2019-12-19T20:18:25Z

@kaimast if you look at how tests are run, you should use limit to --test-threads=1 because the default registered global functions are not accessible in a multi-threaded way. There's no requirement of python binding installed for testing the rust frontend, only if you want to run the resnet example.
