This improvement is due to changes to Gnulib's fprintftime module.
* NEWS: Mention the improvement.
* src/getlimits.c (OFF64_T_MAX, OFF64_T_MIN): New macros.
(main): Print them.
* tests/misc/write-errors.sh: Call getlimits_. Add a date invocation.
* src/local.mk: Revert v9.7-322-gc2e1816a5, instead relying
on the more focused v9.8-79-g532cd66af. When built with
--disable-nls on macOS this will result in only some commands
being linked with INTL_MACOSX_LIBS, thus resulting in env(1)
at least not setting a __CF_USER_TEXT_ENCODING envirnoment variable.
* src/copy-file-data.c (infer_scantype): Fall back to a plain copy
if SEEK_HOLE indicates non-sparse, as zero copy avoids copy offload.
This was seen with transparently compressed files on OpenZFS.
* tests/cp/sparse-perf.sh: Add a test case even though it might
only trigger on compressed file systems that don't support reflink.
* NEWS: Mention the bug fix.
Addresses https://github.com/coreutils/coreutils/issues/122
* NEWS: Remove timeout from the list of programs that use posix_spawn.
* bootstrap.conf (gnulib_modules): Remove posix_spawnattr_setsigmask.
* src/timeout.c: Don't include spawn.h.
(main): Use fork and execvp instead of posix_spawn.
This reverts commit dac96ce3e3.
* NEWS: Mention that we don't fall-back to executing /bin/sh <script>
for malformed scripts that don't start with #!..., or any executable
that returns ENOEXEC in general.
* src/sort.c (main): Ignore SIGPIPE so we've more control over
how we handle for stdout and compression programs.
(sort_die): Handle EPIPE from stdout and mimic a standard SIGPIPE,
otherwise reverting to a standard exit(SORT_FAILURE);
* tests/sort/sort-compress-proc.sh: Add a test case.
* NEWS: Mention the bug fix.
* NEWS: Mention the improvement. Consolidate the posix_spawn
improvements into one item.
* bootstrap.conf (gnulib_modules): Add posix_spawnattr_setsigmask.
* src/timeout.c: Include spawn.h.
(main): Setup signals using a posix_spawnattr_t object. Use posix_spawn
instead of fork and execvp.
The build can be force enabled with --with-selinux and vice versa.
* build-aux/gen-lists-of-programs.sh: Move chcon and runcon
to the list of optional programs.
* configure.ac: Only enable chcon and runcon if selinux.h is available.
* NEWS: Mention the Build-related change.
Fixes https://github.com/coreutils/coreutils/issues/121
* NEWS: Mention the improvement. Mention that 'sort' will continue
without compressing temporary files if the program specified by
--compress-program cannot be executed.
* doc/coreutils.texi (sort invocation): Document the behavior when the
program specified by --compress-program cannot be executed.
* src/sort.c: Include spawn.h.
(MAX_FORK_TRIES_COMPRESS, MAX_FORK_TRIES_DECOMPRESS): Remove definition.
(MAX_TRIES_COMPRESS, MAX_TRIES_DECOMPRESS): New definitions based on
MAX_FORK_TRIES_COMPRESS and MAX_FORK_TRIES_DECOMPRESS.
(async_safe_die): Remove function.
(posix_spawn_file_actions_move_fd): New function.
(pipe_fork): Remove function.
(pipe_child): New function based on pipe_fork. Return an error number
instead of a pid. Use posix_spawnp instead of calling fork and expecting
the caller to exec.
(maybe_create_temp): Call pipe_child instead of pipe_fork. Print a
warning to standard error if --compress-program cannot be executed and
the error is different than the previous call. Remove code for the child
process.
(open_temp): Remove code for the child process. Improve error message.
* tests/sort/sort-compress.sh: Add a test case for when the program
specified by --compress-program does not exist.
* NEWS: Mention the change.
* bootstrap.conf (gnulib_modules): Add posix_spawn,
posix_spawnattr_setsigdefault, posix_spawn_file_actions_addclose,
posix_spawn_file_actions_adddup2, and posix_spawn_file_actions_init.
* src/split.c: Include spawn.h.
(create): Use posix_spawn instead of fork and execl.
* NEWS: Mention the improvement.
* src/fmt.c (put_line): Exit if any error writing line.
(flush_paragraph): Exit if any error writing buffer.
* tests/misc/write-errors.sh: Enable the (flush_paragraph) test case,
and add another to check the put_line() case.
* src/numfmt.c (process line): Inspect the stdio error state when
outputting each line so that we don't have to check each output function
but do eventually exit upon write error, while also remaining buffered.
(main): Also check when outputting a header for the edge case
of very long headers.
* tests/misc/write-errors.sh: Enable the numfmt test case.
* NEWS: Mention the improvement, and reorganize all numfmt improvements.
* NEWS: Mention the change.
* bootstrap.conf (gnulib_modules): Add posix_spawnattr_destroy,
posix_spawnattr_init, posix_spawnattr_setflags, and posix_spawnp.
* src/install.c (strip): Use posix_spawnp instead of fork and execlp.
* bootstrap.conf: Depend on mbsstr() to robustly search for a
multi-byte delimiter character (string) within a multi-byte string.
* src/numfmt.c (main): Accept a valid multi-byte delimiter character.
(next_field): Adjust delimiter search from single byte
to multi-byte aware. Use mbsstr to find the first match.
* tests/misc/numfmt.pl: Add test case.
* NEWS: Mention the improvement.
* src/numfmt.c (process_line): Restore byte overwritten with NUL,
as it may be part of a multi-byte blank.
(process_suffixed_number): Skip multi-byte blanks,
and correctly determine width with mbswidth().
(parse_format_string): Use c_isblank() to explicitly
indicate that's all the format spec supports.
* tests/misc/numfmt.pl: Add test cases.
* NEWS: Mention the bug fix.
Output, accept, or disallow a string between the number and unit
as recommended in <https://physics.nist.gov/cuu/Units/checklist.html>
I.e. support outputting numbers of the form: "1234 M"
* src/numfmt.c (simple_strtod_human): Skip unit separator if present,
or disallow a unit separator if empty.
(double_to_human): Output unit separator if specified.
(main): Accept --unit-separator.

* doc/coreutils.texi: Describe the new option,
giving examples of interaction with --delimiter.
* NEWS: Mention the new feature.
* THANKS.in: Add Johannes Schauer Marin Rodrigues,
who provided a preliminary patch.
This does not validate grouping character placement,
and currently just ignores grouping characters.
* src/numfmt.c (simple_strtod_int): Skip grouping chars
that are part of a number.
* tests/misc/numfmt.pl: Add test cases.
* NEWS: Mention the improvement.
* src/numfmt.c (simple_strtod_human): Accept (multi-byte)
non-breaking space character between number and unit.
Note we restrict this to a single character between number
and unit, to allow less ambiguous parsing if multiple blanks
are used to delimit fields.
* tests/misc/numfmt.pl: Add test cases.
* doc/coreutils.texi (numfmt invocation): Fix stale description
--delimiter skipping whitespace.
* NEWS: Mention the improvement.
* src/digest.c (split_3): Fallback to untagged matching in the
case where -a is specified and we have matched a TAG in
the possibly base64 data. This might happen in 1 in every 64K files.
Note we remove the modification of string S (and redundant streq) in
the tag matching, as that was not needed since v8.32-223-g217cd278e.
* tests/cksum/cksum-c.sh: Add a test case.
* NEWS: Mention the bug fix.
* src/digest.c (sha2_sum_stream): Change from unreachable()
to affirm() so that we have defined behavior unless
we configure with --disable-assert.
(sha3_sum_stream): Likewise.
(split_3): Validate SHA2-lengths before passing on.
* tests/cksum/cksum-c.sh: Add a test case.
* NEWS: Mention the bug fix.
* src/digest.c (split_3): Look up the provided tag with -a sha2
because there is not a 1:1 mapping between them.
* tests/cksum/cksum-c.sh: Add a test case.
* NEWS: Mention the bug fix.
* src/remove.c (rm_fts): When not recursive,
arrange for ‘rm -d DIR’ to behave more like ‘rmdir DIR’.
This works better for Ceph snapshot directories.
Problem reported by Yannick Le Pennec (bug#78245).
* NEWS: Mention the bug.
* src/digest.c (split_3): Check that the base64 digest matches the
length supported by the algorithm.
(digest_check): Check that the read digest matches the base64 length of
the algorithm's digest. The previous condition would not work for
'cksum -a blake2b -l 8 ...'.
* tests/cksum/cksum-base64-untagged.sh: New file.
* tests/local.mk (all_tests): Add the new test.
This avoids CWE-122: Heap-based Buffer Overflow
where we could write blank characters beyond
the allocated heap buffer.
* src/expand-common.c (set_max_column_width): Refactor function from ...
(add_tab_stop): ... here.
(set_extend_size): Call new function.
(set_increment_size): Likewise.
* NEWS: Mention the bug fix.
Fixes https://bugs.gnu.org/79555
* configure.ac: Add detection of AVX512 intrinsics for wc.
* src/local.mk: Build AVX512 wc libraries.
* src/wc.c: Add runtime detection of AVX512 intrinsics and call
appropriate function when detected.
* src/wc.h (wc_lines_avx512): Declare function.
* tests/wc/wc-cpu.sh: Add a test that disables AVX512 intrinsics.
* src/wc_avx512.c: New file containing the wc -l implementation using
AVX512. The logic and code is reused from the AVX2 implementation with
slight adaptations. Replaced __builtin_popcount by __builtin_popcountll
and the combination of _mm256_cmpeq_epi8 and _mm256_movemask_epi8 by a
single call to _mm512_cmpeq_epi8_mask.
* NEWS: Mention the improvement.
* src/tail.c (file_lines): Seek to the previous block instead of the
beginning (or a little before) of the block that was just scanned.
Otherwise, the same block is read and scanned (at least partially)
again. This bug was introduced by commit v9.7-219-g976f8abc1.
* tests/tail/basic-seek.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: mention the bug fix.
base58_length() operated naively on an int
which resulted in an overflow to a negative number
for any input > 2^31-1/138, i.e. 15,561,475 bytes.
* src/basenc.c (base_length): Change input and output
parameter types from int to idx_t since this needs to
cater for the full input size in the base58 case.
(base58_length): Likewise. Also reorder the calculation
to be less exact, but doing the division first
to minimize the chance of overflow (which now on 64 bit
would only happen for inputs > around 6 Exa bytes).
* tests/basenc/basenc-large.sh: Add a new test,
that triggers with valgrind or ASAN.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.
* src/dd.c (v): Add the O_EXCL flag to the set of bits that we do not
want to use for our definitions.
* cfg.mk (sc_dd_O_FLAGS): Adjust to pass syntax-check.
* NEWS: Mention the fix.
Reported by Bruno Haible.
* NEWS: Mention the new GLIBC_TUNABLES feature.
* doc/coreutils.texi (Hardware Acceleration): A new node
detailing the build time and run time configuration options.
* src/fold.c (write_out): A new helper to check all writes.
(fold-file): Use write_out() for all writes.
* tests/fold/fold-zero-width.sh: Adjust to writing more
data in various patterns, rather than two buffers of NULs.
This is a more robust memory bound check, and the '\303' case
tests this particular logic change.
* NEWS: fold now exits immediately, not just promptly.
* NEWS: Mention the improvement.
* src/fold.c (fold_file): Check for write errors
after each buffer read from stdin.
* tests/misc/write-errors.sh: Add test cases.
* NEWS: Before commit fb9016d50 (fold: use fread instead of getline,
2025-08-24), fold required that the maximum line size in a file fit into
memory. Document that this is no longer the case.
The meaning of non-file permission umask bits is implementation defined.
On Bionic libc, attempting to set them triggers a FORTIFY runtime check.
$ nohup true
FORTIFY: umask: called with invalid mask -601
Aborted nohup true
* src/nohup.c: (main) Avoid setting non-permission bits in umask.
Just clear the umask to ensure we create nohup.out with u+rw,
as we restore the original umask before the exec().
* tests/misc/nohup.sh: Add a test case.
* NEWS: Mention the bug fix.
* src/basenc.c (has_padding): A more robust helper to
identify padding in the presence of trailing newlines.
(do_decode): Use has_padding() rather than just looking
at the last character.
* tests/basenc/base64.pl: Fully test commit v9.4-53-g378dc38f4
by ensuring partially padded data is diagnosed.
baddecode9 is the case fixed in this commit.
* NEWS: Mention the bug fix.
To make the interface more concise and consistent,
while being backwards compatible.
* src/digest.c (main): Continue to support -a "sha###" but
also support -a "sha2" and treat it like "sha3", except in...
(output_file): ... maintain the legacy tags for better compatability.
* doc/coreutils.texi (cksum invocation): Document the -a sha2 option.
* tests/cksum/cksum-base64.pl: Adjust as per modified --help.
* tests/cksum/cksum-c.sh: Add new supported SHA2-### tagged variant.
* NEWS: Mention the new feature.
* src/digest.c: Include sha3.h.
(BLAKE2B_MAX_LEN): Rename to
DIGEST_MAX_LEN since it is also used for SHA-3.
(sha3_sum_stream): New function.
(enum Algorithm, algorithm_args, algorithm_args, algorithm_types)
algorithm_tags, algorithm_bits, cksumfns, cksum_output_fns): Add entries
for SHA-3.
(usage): Mention that SHA-3 is supported. Mention requirements for
--length with SHA-3.
(split_3): Use DIGEST_MAX_LEN instead of BLAKE2B_MAX_LEN. Determine the
length of the digest for SHA-3. Make sure it is 224, 256, 384, or 512.
(digest_file): Set the digest length in bytes. Use DIGEST_MAX_LEN
instead of BLAKE2B_MAX_LEN. Always append the digest length to SHA3 in
the output.
(main): Allow the use of --length with 'cksum -a sha3'. Use
DIGEST_MAX_LEN instead of BLAKE2B_MAX_LEN. Make sure it is 224, 256,
384, or 512.
* tests/cksum/cksum-base64.pl (@pairs): Add expected sha3 output.
(fmt): Modify the output to use SHA3-512 since that is the default.
(@Tests): Modify arguments for sha3 to use --length=512.
* tests/cksum/cksum-sha3.sh: New test, based on tests/cksum/b2sum.sh.
* tests/local.mk (all_tests): Add the test.
* bootstrap.conf: Add crypto/sha3.
* gnulib: Update to latest commit.
* NEWS: Mention the change.
* doc/coreutils.texi (cksum general options): Mention sha3 as a
supported argument to the -a option. Mention that 'cksum -a sha3'
supports the --length option. Mention that SHA-3 is considered secure.
* src/seq.c (main): Avoid possibly innacurate conversion
to long double, for all digit start values.
* tests/seq/seq-long-double.sh: Add a test case.
* NEWS: Mention the improvement.
Fixes https://bugs.gnu.org/79369
Fix allocated size alignment in locales with multi-byte grouping chars.
Tested with: LC_ALL=sv_SE.utf8 ls --size --block-size=\'k
* src/ls.c (print_file_name_and_frills): Don't rely on
printf("%*s", width, string) to pad multi-byte strings appropriately.
Instead work out the padding required and use:
printf("%*s%s", padding, "", string) to pad multi-byte appropriately.
* tests/ls/block-size.sh: Add a test case.
* NEWS: Mention the bug fix.
Fixes https://bugs.gnu.org/79347
* src/digest.c (main): Don't saturate -l to BLAKE2B_MAX_LEN,
so that the subsequent bounds check is performed.
* tests/cksum/b2sum.sh: Add a test case.
* NEWS: Mention the fix introduced in commit v9.5-71-gf2c84fe63
