Toolchain variants
Each release ships three Rust-toolchain variants of every binary:
| Suffix | Rust toolchain | Recommended use |
|---|---|---|
| (none) | stable | Default. Use this. |
-beta |
Rust beta | Early adopters validating the next Rust release. |
-nightly |
Rust nightly | Performance experiments and unstable-feature testing. |
The -beta / -nightly suffix denotes the Rust toolchain the artifact was built with - it is not an indicator of oc-rsync's own release maturity (that is set in the release title and README.md).
Security
See SECURITY.md for the canonical mitigation roster and docs/design/sec-1-completion-summary-2026-05-22.md for the SEC-1 sub-task (.a-.p) ship state.
Active mitigations
| CVE | Description | Status | Cite |
|---|---|---|---|
| CVE-2024-12084 | Heap overflow in checksum parsing | Not vulnerable | Rust Vec<u8> handles dynamic sizing |
| CVE-2024-12085 | Uninitialized stack buffer leak | Not vulnerable | Rust requires initialization |
| CVE-2024-12086 | Server leaks client files | Not vulnerable | Strict path validation |
| CVE-2024-12087 | Path traversal via --inc-recursive |
Not vulnerable | Path sanitization |
| CVE-2024-12088 | --safe-links bypass |
Mitigated | Rust path handling |
| CVE-2024-12747 | Symlink race condition | Mitigated | TOCTOU is OS-level |
| CVE-2026-29518 | TOCTOU symlink race in daemon receiver | Fixed | SEC-1.a-q2, SECURITY.md |
| CVE-2026-43617 | Reverse-DNS lookup after daemon chroot | Not vulnerable | Hostname ACL runs before chroot |
| CVE-2026-43618 | Integer overflow in compressed-token decoder | Fixed | Typed CompressedToken enum, SECURITY.md |
| CVE-2026-43619 | Symlink races on chmod/lchown/utimes/rename/unlink/mkdir | Fixed | SEC-1.a-q2, SECURITY.md |
| CVE-2026-43620 | OOB read via negative parent_ndx |

| CVE-2026-45232 | Off-by-one stack write in HTTP CONNECT proxy | Fixed | SEC-2.a-b, SECURITY.md |
Defense-in-depth. This release ships the SEC-1 *at syscall chain (fstatat, unlinkat, mkdirat, symlinkat, linkat, fchmodat, fchownat, utimensat, renameat) routed through a per-transfer DirSandbox carrier with openat2(RESOLVE_BENEATH | RESOLVE_NO_SYMLINKS) runtime detection. The optional landlock Cargo feature (Linux 5.13+) layers kernel-enforced PathBeneath allowlisting on top; daemons on older kernels run with the *at chain as the sole TOCTOU defense, which is itself sufficient against CVE-2026-29518 / CVE-2026-43619.
Kernel / platform compatibility
| Layer | Minimum | Notes |
|---|---|---|
| io_uring data path | Linux 5.6+ | Runtime-probed; falls back to standard buffered I/O. |
| Provided buffer rings (PBUF_RING) | Linux 5.19+ | Runtime-probed; falls back to standard buffered I/O. |
Landlock LSM (landlock feature) |
Linux 5.13+ | Best-effort ABI downgrade; no-op on older kernels. |
IORING_OP_SEND_ZC (iouring-send-zc feature) |
Linux 6.0+ recommended | Opt-in; default builds use plain IORING_OP_SEND. |
macOS *at chain |
macOS 10.10+ | BSD *at family verified at parity with Linux (SEC-1.k). |
| Windows IOCP | Windows 10 1809+ | NTFS handle-based APIs sidestep path TOCTOU structurally (SEC-1.l). |
Distro packagers: see docs/packaging/landlock-feature-guidance.md for the per-distro --features landlock recommendation, runtime ABI matrix, and build-time dependency notes.
Supported rsync protocol versions
Protocol versions 28-32 (upstream rsync 2.6.x-3.4.x). Protocols <= 27 unsupported. Per-opcode kernel floor: docs/audit/iouring-opcode-kernel-floor.md.

v0.5.7
What's Changed
- Stream whole-file transfers in a single pass, eliminating per-file buffer allocations.
- Fix push-to-daemon protocol (MultiplexWriter optimizations, correct sender-side framing).
- Reduce per-file allocation overhead: stack-based checksum finalization, PathBuf ownership transfer, Vec pre-allocation.
- Increase daemon integration test timeout for nightly CI stability.

v0.5.4
What's Changed
This release is all about performance optimizations.
I added performance benchmark vs upstream rsync using Linux to the release to track performance regressions better.
While I do track and optimize performance metrics on other platforms my focus is Linux performance.
A container image based on Alpine Linux is now available at https://github.com/oferchen/rsync/pkgs/container/oc-rsync
