Rust Coreutils 0.10.0 Release:

We are happy to announce the release of Rust Coreutils 0.10.0 - a release focused on GNU compatibility and robustness. The GNU test suite results improved sharply this cycle (645 passing, 29 failing, down from 56), we landed a second wave of security hardening (TOCTOU races, safe recursive descent, SELinux labeling at creation, backup guards), and we ran a broad anti-panic campaign across the utilities. On top of that: new features (mv --exchange and an OpenSSL backend for the checksum utilities), more zero-copy/read-ahead performance work, and wasm32-wasip2 support.

GNU Test Suite Compatibility:

Note: 0.9.0 bumped the GNU reference to 9.11, which added 25 new tests and temporarily pushed the failure count up. This cycle absorbed most of that debt: failures dropped from 56 to 29 and passes reached an all-time high of 645.
As we contributed many tests to the GNU implementation, we are also the source of some of these regressions!

Highlights:

• GNU Compatibility

  • 645 passing GNU tests (+20) and 27 fewer failures, the largest single-cycle drop we have had
  • Dozens of behavior alignments: pr (-w/-W/-l/-e/-o, merge mode, page ranges), nproc (cgroups v2 quota, affinity mask, offline cores, OMP_* handling), date (out-of-range years, -d -, O modifier, timezone strings), numfmt, ls, du, install, od, truncate, fold, head/tail, sum, stat
  • Many error messages now carry the file name and the real OS error instead of a vague or stripped message

• Security Hardening

  • Continued the TOCTOU work started in 0.9.0: touch no longer uses O_TRUNC on create, mkfifo drops the path-based chmod, head checks the open fd instead of the path, split hardens the output-open path, chcon anchors recursive relabeling to the traversal dirfd
  • Safe recursive descent fixes for chmod/chown (symlink cycles, --preserve-root re-checked during the descent), and cp no longer descends into a destination subdirectory that is a symlink
  • SELinux labels are now applied at creation in mkdir, mkfifo and mknod instead of being applied afterwards
  • mv fails closed when recreating a cross-device directory destination, compares file identity in the --backup=simple guard, and strips setuid/setgid when a cross-device copy cannot preserve ownership
  • chroot chroots exactly the path --skip-chdir validated; stdbuf refuses a libstdbuf path that cannot be represented in LD_PRELOAD; install finalizes ownership before mode
  • Added SECURITY.md documenting our threat model, scope and reporting process

• Robustness: Anti-Panic Campaign

  • Removed panics and aborts across a long list of utilities: shuf, printf, numfmt, fmt, pr, chroot, dircolors, install, ln, touch, stat, split, expand, more, kill, cp, du, rm, runcon, sort, chown/chgrp, dirname, expr, cksum, dd, truncate, hashsum
  • Recurring classes fixed: write failures on /dev/full, char-boundary panics on multibyte input, integer overflow on extreme widths/precisions/sizes, and unbounded allocations for huge arguments
  • expr now uses an iterative parser, so deeply nested expressions no longer overflow the stack

• New Features

  • mv --exchange to atomically swap two paths
  • install --reflink support, and install -C now works with --preserve-timestamps
  • OpenSSL backend for the faster checksum utilities
  • cut -O as a short option for --output-delimiter
  • rm --one-file-system
  • timeout now works on Windows, and tail -f/-F finally follows files on Windows

• Performance

  • Read-ahead hints across the cksum family, sum, split, expand/unexpand and the base* utilities
  • tee zero-copy fast path; cat throughput improvements; faster non-reflink cp; cross-device mv via the fast copy path
  • expr: index went from O(N*M) to O(N+M); uniq and du improvements; tsort now buffers its output
  • New benchmarks for expr, tr, cut, uniq and locale-aware sort merges

• Internationalization

  • cut supports multibyte characters in non-UTF-8 locales
  • ls uses Unicode quotes for the locale/clocale styles in UTF-8 locales and escapes non-ASCII control characters
  • Fixed C.UTF-8 being detected as ASCII, and incomplete Fluent fallback bundles
  • cksum quotes file names in a locale-aware way

• Cross-platform Reach

  • New wasm32-wasip2 target support
  • Windows: timeout implementation, sparse copy support in cp, tail -f, cksum CRLF fix
  • ls --numeric-uid-gid on non-unix platforms, uptime uses CLOCK_BOOTTIME on more platforms

• Code Quality

  • clippy::collapsible_if and clippy::match_same_arms are now clean and enabled workspace-wide
  • Continued nix → rustix migration (dd, kill, sync, uptime) and further removal of unsafe and to_string_lossy

• Contributions: This release was made possible by 50 new contributors joining our community

Rust Coreutils 0.9.0 Release:

We are excited to announce the release of Rust Coreutils 0.9.0 - a release focused on safety and security. This cycle was shaped by a third-party security audit, driving extensive TOCTOU hardening and a sustained, project-wide effort to shrink the amount of unsafe code by removing it outright and migrating low-level syscalls from nix/libc to rustix. On top of that, we landed major zero-copy I/O performance work (splice/tee/pipe), broadened WebAssembly, Cygwin and Windows support, and continued contributing tests and bug reports upstream to GNU coreutils.

GNU Test Suite Compatibility:

Note: The rise in failing tests is due to the upstream GNU test suite being extended, not to regressions on our side. We updated our GNU reference from 9.10 to 9.11 (PR #11922), which added 25 new tests (665 → 690). Many of these newly-introduced tests are not yet passing, which accounts for the jump from 21 to 56 failures; no previously-passing functionality regressed, and work is ongoing to address the new tests.

Highlights:

• Security Hardening (Zellic audit)

  • A third-party security audit by Zellic reviewed the codebase; the findings - widely reported as 44 CVEs (see also the Ubuntu update and the corrode write-up Bugs Rust won't catch) - were concentrated in TOCTOU races and filesystem edge cases that Rust's type system does not prevent
  • It's worth noting that many of these CVEs are not memory-safety issues but differences in behavior from GNU coreutils that the audit identified; aligning our semantics with GNU resolves them
  • This release closes many of them: a new TOCTOU-resistant uucore::safe_copy module; TOCTOU fixes in cp, mv, and chmod recursive traversal; rm dot/dotdot path-parsing protection; nohup.out now created with mode 0600; and chroot now resolves all ids before chrooting

• Reducing unsafe & migrating to rustix

  • A sustained, project-wide push to shrink the unsafe surface: dozens of unsafe removals across utilities, tests, fuzz targets and uucore (get_groups, make_fifo, build.rs, and more)
  • Migration from nix/libc to rustix across id, tr, timeout, sort, wc, tail, cp, who, factor, and core process/IO paths

• Performance

  • splice()/tee()/pipe() fast paths landed across cat, wc, head, tail, yes, cp, tee, and unexpand (e.g. unexpand +7.5%, faster cp from a pipe on Linux, tee via raw syscalls, yes using the tee syscall)
  • Consolidated in a reworked uucore::pipes / buf_copy

• GNU Compatibility & Upstream Collaboration

  • Reference bumped to GNU 9.11, which extended the suite with 25 new tests (the reason the failure count went up - see the note above; it is not a regression)
  • We continue to contribute tests and bug reports upstream to GNU coreutils, and our compatibility work keeps surfacing edge cases on both sides
  • New fixes across numfmt, date, tr, cksum, factor, head, stat, and sort

• numfmt Overhaul

  • Precision handling, rejection of scientific notation, LC_NUMERIC decimal separator, zero-padding for negative numbers, IEC precision cap, large %f values, --to=auto exit code, and multi-byte --suffix width accounting

• ls Improvements

  • ls -lF symlink target indicators, link-count column no longer inflated per-ACL-file, version-sorting and recursive-mode fixes, independent permissions-column width
  • Refactor letting crate users (e.g. nushell) call ls without writing everything to stdout

• Cross-platform Reach

  • WASI/wasm support for ln, dd, mktemp, and tty.wasm; Cygwin CI and builds (date, stdbuf); Windows tty (incl. msys2 paths); OpenBSD triage improvements

• Internationalization

  • numfmt and du now honor LC_NUMERIC for the decimal separator

• Contributions: This release was made possible by 30 new contributors joining our community
