rustup: rustup-init hangs in armv7 docker container running on an arm64 Linux with `reqwest` backend

Problem

Running curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh in armv7 docker container running on an arm64 Linux hangs.

Steps

Run a docker container with --platform linux/arm/v7 on an arm64 Linux, install curl and run the sh.rustup.sh script

$ docker run --rm -it --platform linux/arm/v7 ubuntu:22.04 bash
root@668fa2822782:/# apt update && apt install curl -y
root@668fa2822782:/# curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y --verbose
info: downloading installer
info: profile set to 'default'
info: default host triple is aarch64-unknown-linux-gnu
verbose: installing toolchain 'stable-aarch64-unknown-linux-gnu'
verbose: toolchain directory: '/root/.rustup/toolchains/stable-aarch64-unknown-linux-gnu'
info: syncing channel updates for 'stable-aarch64-unknown-linux-gnu'

hangs forever at the verbose: downloading with reqwest step, use RUSTUP_USE_CURL=1 works fine

I tried to disable cURL and use the default reqwest backend instead with the 1.27 beta, and it also didn’t change anything compared to before.

Here is the output:

For good measure I also tried the same Dockerfile but with Ubuntu 18.04, 20.04 and 22.04 and I see the exact same behaviour across all of them.

That certainly looks like docker is providing the host’s cpuinfo through. This is the issue we had on reqwest - https://github.com/seanmonstar/reqwest/issues/642 which eventually boiled down to https://github.com/lxc/lxcfs/issues/553 which is what eventually fixed it in that case - I wonder if Docker needs equivalent help.
