GHSA-R9HW-MJ3W-PHCQ mknod: Device nodes created mislabeled on SELinux, with broken cleanup (remove_dir on a node)

uutils calls mknod before setting the SELinux context GNU uses setfscreatecon first, labeling atomically. If setselinuxsecuritycontext fails, cleanup uses std::fs::removedir, which cannot remove device nodes or FIFOs, leaving the mislabeled node behind. Impact: on SELinux-enforcing systems the no...
