Landlock support #1550
Description
Having searched through issues and PRs I have not seen any direct mentions of adding support for Landlock - the new-ish userspace-sandboxing syscalls initially added in the Linux kernel version 5.13, so here is that mention.
Documentation for the kernel feature is available here.
There is already a crate made by the original author, which is actively maintaining it. However, it directly uses libc for the syscalls, thus is not purely written in Rust, which is a shame.
Is there interest in adding support for the landlock syscalls directly in rustix or should one use the official landlock crate instead and have to live with the libc dependency?
