Calling `unwrap` on the result of `CString::new` may cause the current thread to panic, which is a bit surprising undocumented behavior. It would be more reasonable to treat the erroneous name as a non-existing user or group.
This is a backport of 006fc6f. The original commit message follows: In a future release of the `libc` crate, `libc::timespec` will contain private padding fields on `*-linux-musl` targets and so the struct will no longer be able to be created using the literal initialization syntax. Update places where `libc::timespec` is created to first zero initialize the value and then update the `tv_sec` and `tv_nsec` fields manually. Many of these places are in `const fn`s so a helper function `zero_init_timespec()` is introduced to help with this as `std::mem::MaybeUninit::zeroed()` is not a `const` function. Some matches on `libc::timespec` are also updated to include a trailing `..` pattern which works when `libc::timespec` has additional, private fields as well as when it does not (like for `x86_64-unknown-linux-gnu`).
It just so happens that Redox, OpenBSD, Dragonfly, and uclibc don't use some of the rules for two internal macros.
