Re: [apache/incubator-teaclave-sgx-sdk] Implement enclave memory management (PR #436)
@yangfh2004 Hello, I'm pleased to know that the EDMM feature has been integrated into your project. Unfortunately, the simulation mode (SW mode) for EDMM is not on our current roadmap, primarily because Intel does not offer support for EDMM in SW mode, and I am currently at full capacity, preventing me from undertaking the implementation of this feature. However, conceptually speaking, I believe the SW mode could be relatively straightforward to implement using system calls like mmap and munmap. -- Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/436#issuecomment-2133031533 You are receiving this because you are subscribed to this thread.

@ClawSeven Hi, our team is using your emm branch, which works OK. But we want to request some supports to the simulation mode (SW mode) so that we can build and run our enclave without sgx drivers. Do you have a chance to add SW supports to your branch?

@yangfh2004 Btw, I have tested the `httpreq` with `rustc 1.78.0-nightly (397937d81 2024-02-22)`. It also worked well. -- Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/436#issuecomment-1960986008 You are receiving this because you are subscribed to this thread.

@yangfh2004 , Hi, thanks for your two issue. 1. Regarding the first issue, I have managed to replicate it and have confirmed that the Makefile for the EMM sample code indeed requires thread feature activation. I will address and resolve this promptly. 2. As for the second issue, I am unable to reproduce the scenario you've described. In my environment, the `httpreq` sample code works well without any panic. Could you please provide the version of your toolchain so that I can further investigate this matter? -- Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/436#issuecomment-1960966112 You are receiving this because you are subscribed to this thread.

The second issue has an easy fix, essentially, all problems are due to the alignment checks in dereference of raw pointers. We just need to use `read_unaligned` or `write_unaligned` -- Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/436#issuecomment-1952851066 You are receiving this because you are subscribed to this thread.

Thanks a lot for your reply, we are using SGX2 on 3rd Gen Xeon Scalable Processor with MKTME, and we will need large dynamic heap allocations. We are now using v1.1.6 with Intel SGX SDK 2.21. We are trying to upgrade to v2.0.0 with support to the later Rust toolchain. -- Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/436#issuecomment-1951412654 You are receiving this because you are subscribed to this thread.

@ClawSeven Hi, I notice two issues with your PR: 1. your `emm` sample code cannot be built with `BUILD_STD=cargo` 2. I merged your commits in this PR into the current `v2.0.0-preview` branch to support the latest rust toolchain as this [fork branch](https://gitlab.com/dexlabs/incubator-teaclave-sgx-sdk/-/tree/v2.0.0-sgx-emm?ref_type=heads), however, I see problems with `httpreq` sample code, it will have pointer alignment issues while doing ocall "u_getaddrinfo_ocall", the pointer address of the argument and the return value is misaligned, which will cause panic in the repo. It seems that your implementation has some conflicts with the recent Rust toolchain.
