rust: library: Add `setsid` method to `CommandExt` trait Add a setsid method to the CommandExt trait so that callers can create a process in a new session and process group whilst still using the POSIX spawn fast path. Tracking issue: rust-lang/rust#105376 ACP: https://github.com/rust-lang/libs-team/issues/184 This PR was previously submitted by ``@HarveyHunt`` (whom I marked as Co-Author in the commit message) in rust-lang/rust#105377. However that PR went stale. I applied the [suggestion](https://github.com/rust-lang/rust/pull/105377/files/231d19fcbfe155b2e85116865adae4253380ff1f#r1893457943) to change the function signature to `fn setsid(&mut self, setsid: bool) -> &mut Command`.

std: fix aliasing bug in UNIX process implementation

2025-05-23T15:09:00+00:00

`CStringArray` contained both `CString`s and their pointers. Unfortunately, since `CString` uses `Box`, moving the `CString`s into the `Vec` can (under stacked borrows) invalidate the pointer to the string, meaning the resulting `Vec<*const c_char>` was, from an opsem perspective, unusable. This PR removes removes the `Vec` from `CStringArray`, instead recreating the `CString`/`CStr` from the pointers when necessary. Also,`CStringArray` is now used for the process args as well, the old implementation was suffering from the same kind of bug.

Add `std::os::unix::process::CommandExt::chroot` to safely chroot a child process

2025-05-20T16:25:05+00:00

This adds a `chroot` method to the `CommandExt` extension trait for the `Command` builder, to set a directory to chroot into. This will chroot the child process into that directory right before calling chdir for the `Command`'s working directory. To avoid allowing a process to have a working directory outside of the chroot, if the `Command` does not yet have a working directory set, `chroot` will set its working directory to "/".

collect all Fuchsia bindings into the `fuchsia` module The Fuchsia bindings are currently spread out across multiple modules in `sys/pal/unix` leading to unnecessary duplication. This PR moves all of these definitions into `sys::pal::unix::fuchsia` and additionally: * deduplicates the definitions * makes the error names consistent * marks `zx_thread_self` and `zx_clock_get_monotonic` as safe extern functions * removes unused items (there's no need to maintain these bindings if we're not going to use them) * removes the documentation for the definitions (contributors should always consult the platform documentation, duplicating that here is just an extra maintenance burden) `@rustbot` ping fuchsia
