- Changelog
3.4.2
SECURITY RELATED:
	Several security-relevant defects were reported and fixed since 3.4.1.
	None were assigned a CVE — rsync's fork-per-connection design scopes
	the impact of each of these to the attacker's own connection, which is
	equivalent to the client closing the socket itself — but they are
	fixed here as a matter of hygiene and to reduce the chances of a
	future exploitable combination.  Many thanks to the external
	researchers who reported these issues.
	- Fixed a signed integer overflow in the PROXY protocol v2 header
	  parser: a negative `len` field could bypass the size check and cause
	  a stack buffer overflow in `read_buf()`.  Reported by John Walker of
	  ZeroPath.
	- Fixed an invalid access to the files array.  Reported by Calum
	  Hutton of Rapid7.
	- Reject negative token values in the compressed-stream token
	  decoder; a negative value could cause callers to misinterpret a
	  missing data pointer as literal data.  Reported by Will Sergeant.
	- Fixed the element count passed to the xattr `qsort()` (see
	  https://www.openwall.com/lists/oss-security/2026/04/16/2).
	- Fixed a buffer underflow in `clean_fname()`, and added a regression
	  test.
	- Fixed an uninitialized `mul_one` in the AVX2 get_checksum1 path
	  (undefined behaviour), and added a SIMD-checksum self-test that
	  cross-checks SSE2, SSSE3 and AVX2 against the C reference on both
	  aligned and unaligned buffers.
	- Fixed an uninitialized `buf1` on the first call to
	  `get_checksum2()` in the MD4 path (fixes #673).
	- Zero all new memory from internal allocations: `my_alloc()` now uses
	  `calloc`, and `expand_item_list()` zeros the expanded portion after
	  `realloc`.  This gives more predictable behaviour if stale or
	  uninitialised memory is ever accidentally read.
BUG FIXES:
	- Call `tzset()` before chroot so that log timestamps continue to
	  reflect the configured local timezone after the daemon chroots
	  (glibc needs `/etc/localtime`, which is unreachable post-chroot).
	- Use the correct time when writing to the log file.
	- Do not clear `DISPLAY` unconditionally.
	- Fixed a Y2038 bug in `syscall.c` by replacing the `Int32x32To64`
	  macro (which truncates its arguments to 32 bits) with a plain
	  64-bit multiplication.
	- Fixed ACL ID mapping for non-root users (closes #618).
	- Fixed handling of objects with many xattrs on FreeBSD.
	- Fixed `--open-noatime` not taking effect when opening regular
	  files: `O_NOATIME` is now also passed to `do_open_nofollow()`, which
	  has been used for regular files since the CVE fix "fixed symlink
	  race condition in sender".
	- Ignore "directory has vanished" errors.
	- Fixed the removal of multiple leading slashes.
	- Added the missing `--dirs` long option.
	- Fixed a segfault if `poptGetContext()` returns NULL (e.g. under
	  OOM) by not passing NULL to `poptReadDefaultConfig()`.  Reported by
	  Ronnie Sahlberg; found with `malloc-fail-tester`.
	- Fixed a build error on ia64 NonStop (which treats missing
	  prototypes as an error, not a warning).
	- Fixed a flaky hardlinks test (fixes #735).
ENHANCEMENTS:
	- Added multi-threaded `zstd` compression, gated by a new
	  `--compress-threads=N` option, with validation and man-page
	  coverage.
	- Documented the `temp dir` parameter in the rsyncd.conf man page
	  (fixes #820).
	- Improved rendering of interior dashes in long-option names in
	  `md-convert` (perhaps fixes #686).
PORTABILITY / BUILD:
	- Fixed glibc 2.43 const-preserving overloads of `strtok()`,
	  `strchr()` etc. by declaring the affected locals with the right
	  constness.  Contributed by Holger Hoffstätte.
	- Converted the bundled zlib 1.2.8 from K&R-style function
	  definitions to ANSI prototypes, so it builds with clang 16+.
	- Avoid using `bool` as an identifier; it is a keyword in C23.
	- `configure.ac`: check for xattr functions in libc first and only
	  fall back to `-lattr`, avoiding spurious overlinking when `-lattr`
	  happens to be installed.  Contributed by Eli Schwartz.
	- Made the build reproducible by honouring `SOURCE_DATE_EPOCH` for
	  the manpage date.
	- Removed obsolete `popt/findme.c` and `popt/findme.h` that upstream
	  popt 1.14 folded into `popt.c` (fixes #710).  Contributed by Alan
	  Coopersmith.
INTERNAL:
	- Made many module-global variables `const` so they can live in
	  `.rodata` and enable additional compiler optimization.
DEVELOPER RELATED:
	- Replaced `runtests.sh` with `runtests.py`, a Python test runner
	  that supports `--valgrind` (with per-process log files so valgrind
	  output no longer interferes with output comparisons) and
	  `-j/--parallel` execution for roughly a 7× speed-up on typical
	  hardware.
	- Added a SIMD checksum self-test and a `clean-fname-underflow`
	  regression test.
	- Various CI fixes for macOS and Cygwin (including adding
	  `simd-checksum` to the expected-skipped lists on platforms without
	  SIMD), and tests now run on `ubuntu-latest`.
	- removed support for the unmaintained rsync-patches archive
