arm-unknown-linux-gnueabihf build failed #427

Problem:

  Copying platform assembly files from /cargo/registry/src/index.crates.io-6f17d22bba15001f/aws-lc-sys-0.17.0/aws-lc/generated-src/linux-arm/crypto/ to /target/arm-unknown-linux-gnueabihf/release/build/aws-lc-sys-f9c203f2eb6d1229/out/build/aws-lc/crypto

                                        AT_HWCAP

It looks like that AT_HWCAP2 was missing.

It could be reproduced in this project: https://github.com/shadowsocks/shadowsocks-rust by running:

cross build --release --target arm-unknown-linux-gnueabihf --features "full"

I believe the problem related to the Cross.toml configuration that you have here. See my comment on your other issue. Since I believe these have the same root cause, I will close this issue.

rustls v0.23 starts to use aws-lc as the default crypto implementation. But now not all the dependencies are upgraded to the latest rustls. If there are still any older version of rustls exists in the build process, aws-lc may fails. - ref aws/aws-lc-rs#428 - ref aws/aws-lc-rs#427 - ref aws/aws-lc-rs#426

rami3l · 2024-06-29T01:53:33Z

@justsmth Wait, actually Rustup is now on the same boat (again with rust-lang/rustup#3898) 😅 For cross compilation we have historically used the Docker images provided by rust-lang/rust, and maybe that error was caused by a very outdated version of GCC (we use 8.5.0, and the log above uses 8.3.0)?

The log here is more or less the same thing: https://github.com/rust-lang/rustup/actions/runs/9720503984/job/26831972336?pr=3898

I mean I could try to use cross on our side instead but that migration might not be easy :]

rami3l · 2024-06-30T14:28:53Z

The real problem is, since I have no intention of using fipsmodule (it's not supported for the target in question according to https://aws.github.io/aws-lc-rs/requirements/linux.html), why I'm getting an error on that part of the codebase?

justsmth · 2024-06-30T17:10:08Z

..., why I'm getting an error on that part of the codebase?

It's just due to how the code is structured. Code that is related to the certification has been placed into a "fipsmodule" directory, but the additional "delocation" and runtime checks required for certification are only activated for a "FIPS" build. We have some detail about how a "FIPS" build differs from our default build here: https://github.com/aws/aws-lc/blob/main/crypto/fipsmodule/FIPS.md

I have a fairly simple patch for it, but I need to test it:

@justsmth Thanks! The patch looks reasonable to me. Is there a way I can easily test it within the current cargo setup though?

The change to address this in AWS-LC made it into the release yesterday: https://github.com/aws/aws-lc/releases/tag/v1.31.0

Hopefully, we can get a PR up today for aws-lc-sys to align it with that release.

justsmth · 2024-07-18T19:18:08Z

This should be resolved with our latest release: https://github.com/aws/aws-lc-rs/releases/tag/v1.8.1
