	version 9.5
	* NEWS: Record release date.

2024-03-27  Bruno Haible  <bruno@clisp.org>

	tests: od: avoid outputting undefined floating point values
	od was seen to abort() on glibc on ia64 and m68k with the error:
	Fatal glibc error: printf_fp.c:501 (__printf_fp_buffer_1):
	assertion failed:
	  cy == 1 || (p.frac[p.fracsize - 2] == 0 && p.frac[0] == 0)

	* tests/od/od-multiple-t.sh: Avoid outputting long double floats
	to avoid undefined behavior. 'float' and 'double' are standardized
	by IEEE 754 (except on Linux/m68k) and don't have undefined values.

	build: update with gnulib fixes
	* gnulib: Update to incorporate gnulib fixes
	from Bruno Haible

	tests: numfmt: fix false failures on some systems
	* tests/misc/numfmt.pl: Verify that printf field width specs
	count characters and not bytes before enabling locale tests.
	This was seen on FreeBSD 14.0 and Solaris 11 OpenIndiana.
	Reported by Bruno Haible

	ls: avoid ENOENT from readdir() on FreeBSD 14
	* src/ls.c (print_dir): readdir() on FreeBSD 14 was
	seen to pass ENOENT through.  ENOENT in this context
	means "Directory unlinked but still open".
	Reported by Bruno Haible with tests/ls/removed-directory.sh

2024-03-26  Pádraig Brady  <P@draigBrady.com>

	tests: avoid false failure due to mismatched isblank()
	There is a mismatch between isblank() used by tr and c32isblank() now
	used by uniq on Solaris 11 OpenIndiana. isblank() was seen to return
	true for non breaking space, while c32isblank() returned false.
	Interestingly on Solaris, non breaking space is considered a blank
	character, and isblank() and c32isblank() honor this in all locales.

	* tests/uniq/uniq.pl: Adjust the blank check to use join(1) rather than
	tr(1), as join uses the same blank determination routines as uniq(1).

	cp: with --no-preserve=mode ensure set-group-ID bits maintained on dirs
	This issue was introduced in commit v8.19-145-g24ebca6

	* src/copy.c (copy_internal): On systems that don't support ACLs,
	the fallback default chmod done on directories should maintain
	the set-group-ID, as that's generally auto-set by the system.
	* NEWS: Mention the fix.
	Reported by Bruno Haible on Alpine (with tests/cp/preserve-mode.sh)

2024-03-25  Pádraig Brady  <P@draigBrady.com>

	tests: avoid false failure with partial locale info
	* tests/misc/numfmt.pl: Some systems with the fr_FR.UTF-8
	locale installed, do not have a thousands grouping character defined.
	In this case we skip the locale tests which depend on a non empty
	grouping character.

	tests: avoid triggering obsolete tail option processing
	* tests/ls/dired.sh: With 2 options, the latter is taken
	as a file name on some systems.  This avoids a false
	failure on Solaris and FreeBSD at least.

	tests: remove debugging from a test
	* tests/ls/dired.sh: Remove temp debugging output.

	tests: fix false failure on systems that can chmod symlinks
	* tests/chmod/symlinks.sh: The count of adjusted modes was
	one more on systems where symlink modes can be adjusted.
	Therefore only include the non symlinks in the count.

	doc: fix translation issue in chown/chgrp amalgamation
	* src/chown-core.h (emit_from_option_description): The conditional
	string composition here caused issues for translators.
	Instead move to a more general description ...
	(src/chown.c (usage): ... here.
	Fixes https://bugs.gnu.org/69985

	doc: fix various translation issues
	 src/chown.c (usage): Translate parameterized strings.
	 src/copy.c (copy_internal): Translate each part of ternary.
	* src/cp.c (usage): Fix typo; s/exisiting/existing/.

	test: avoid false failure with setgid directories
	* tests/chmod/symlinks.sh: Ensure this new test is immune
	to setgid directories by resetting modes with =777 rather than 777.
	Also output more debugging in all failure cases.

	tests: avoid false failure on new mv --exchange test
	* tests/mv/mv-exchange.sh: Canonicalize different
	"operation not supported" messages, so we can ignore correctly.
	Reported by Bruno Haible on AIX, NetBSD, and OpenBSD.

	doc: update THANKS related to env --argv0 option
	* THANKS.in: Add Matheus who was central to the env --argv0
	addition in commit v9.4-167-g193449b17.

	mv: treat --exchange more like non-exchange
	Also, improve quality of diagnostics.
	Problems/suggestions by Bernhard Voelker in
	<https://bugs.gnu.org/69532#82>.
	* src/copy.c (emit_verbose): New arg FORMAT.  All uses changed,
	to improve quality of diagnostics when --exchange is used.
	(copy_internal): Don’t try to optimize --exchange so much; this
	simplifies the code and keeps it closer to the non --exchange case.

	cp,ln,mv: improve dir vs nondir diagnostics
	* src/copy.c (copy_internal): Simplify logic for copying
	from directory to non-directory or vice versa, and always

2024-03-22  Pádraig Brady  <P@draigBrady.com>

	env: add -a,--argv0 to set the first argument passed to exec
	Using the shell's exec -a feature can be awkward
	so add support for setting overriding argv[0].
	This gives env full control over the arguments it passes.

	* src/env.c: Accept -a,--argv0 and set argv[0] appropriately.
	* tests/env/env.sh: Add test cases.

	chmod: fix TOCTOU security issue with symlink replacement
	This is an issue with -[H]R mode, where an attacker
	may replace a traversed file with a symlink
	between where we stat() the file and chmod() the file.

	* src/chmod.c (process_file): Remove the first !S_ISLNK guard
	as that's now just an optimization, and instead consistently
	apply fchmodat() to files/symlinks.  Ensure AT_SYMLINK_NOFOLLOW
	is set when traversing in default (-H) mode.
	* NEWS: Mention the bug fix.
	Fixes https://bugs.gnu.org/11108

2024-03-19  Pádraig Brady  <P@draigBrady.com>

	chmod: add support for -h, -H,-L,-P, --dereference options
	There have been various requests to add -h to avoid following symlinks
	for security reasons.  This wasn't provided previously as chmod(1)
	already ignored symlinks unless specified on the command line.
	Note chmod defaults to -H mode rather than the chown default of -P,
	as usually chown can work directly on symlinks and so defaults
	to not traversing those specified on the command line.
	Note FreeBSD chmod does default to -P mode, but we retain the -H mode
	default also for compatibility with existing chmod behavior.

	Adding -HLP will allow chmod to disable traversing CLI symlinks to dirs.
	Adding -h will allow to disable following CLI symlinks to files/dirs,
	  also operating on all symlinks on systems that support that.
	Adding --dereference will be significant with -H (the default).  I.e.
	  symlinks to dirs not recursed, but symlinks are dereferenced.
	Adding these options will also be consistent with chown(1), chgrp(1),
	and chmod(1) on other systems.

	Note since chmod(1) currently ignores symlinks by default,
	and -h is primarily a mechanism to avoid following symlinks, rather than
	for operating on the symlink itself, we make -h try to chmod a symlink,
	but ignore ENOTSUP.  In that way we're consistent with chown(1)
	where it also ignores ENOTSUP for symlinks, and we don't fail when
	trying to be extra secure with command line params.

	* doc/coreutils.texi (chmod invocation): Reference the -H,-L,-P
	descriptions, and adjust the corresponding macros to say
	the default is -H or -P as appropriate.
	Add --dereference and -h,--no-dereference descriptions.
	* man/chmod.x: Adjust discussion of symlink handling.
	* src/chmod.c (main): Accept new options and set
	fts flags appropriately.
	(process_file): Process / dereference symlinks as necessary.
	* src/system.h (emit_symlink_recurse_options): A new function
	refactored from chown.c and chmod.c usage().
	* tests/chmod/symlinks.sh: New test for the new options.
	* tests/local.mk: Reference the new test.
	* NEWS: Mention the new feature.

	maint: basenc: consistently check buffer bounds when encoding
	* src/basenc.c (base16_encode, base2msbf_encode, base2lsbf_encode):
	Ensure we don't overflow the output buffer, whose length is
	passed in the OUTLEN parameter.  This issue was flagged by clang
	with -Wunused-but-set-parameter.

2024-03-19  Pádraig Brady  <P@draigBrady.com>

	pinky: disable location canonicalization by default
	Behave like who(1) in requiring --lookup to enable this
	often slow feature.  pinky(1) is supposed to be lightweight after all.

	* doc/coreutils.texi (who invocation): Adjust the description to no
	longer reference dialup, and be more general about the still significant
	delays.
	(pinky invocation): Reference the same --lookup description.
	* src/pinky.c (main): Accept --lookup to enable DNS lookups.
	* NEWS: Mention the change in behavior.
	Fixes https://bugs.debian.org/628815

2024-03-18  Pádraig Brady  <P@draigBrady.com>

	doc: fix stale --dereference info for chown/chgrp
	Following v5.2.1-679-g7e29ef8b8 symlinks specified on the command line
	no longer induce an error if lchown() is not supported on the system.

	* doc/coreutils.texi (chown invocation, chgrp invocation): Adjust
	accordingly, and also use a macro to avoid duplication.
	* src/chown-core.c: Use our more standard is_ENOTSUP() wrapper
	in the code related to this.

	build: update gnulib submodule to latest

2024-03-15  Pádraig Brady  <P@draigBrady.com>

	build: provide a cross-compiling default for 16 bit float checks
	* configure.ac: Provide a conservative 16 bit float support default
	when cross-compiling, to avoid configure failing in that case.

2024-03-13  Grisha Levit  <grishalevit@gmail.com>

	env,kill,timeout: support unnamed signals
	Some signals with values less that the max signal number for the system
	do not have defined names.  For example, currently on amd64 Linux,
	signals 32 and 33 do not have defined names, and Android has a wider
	gap of undefined names where it reserves some realtime signals.

	Previously the signal listing in env ended up reusing the name
	of the last printed valid signal (the repeated HUP below):

	    $ env --list-signal-handling true
	    HUP        ( 1): IGNORE
	    HUP        (32): BLOCK
	    HUP        (38): IGNORE

	..and the corresponding signal numbers were rejected as operands for the
	env, kill, and timeout commands.

	This patch removes the requirement that sig2str returns 0 for a signal
	number associated with an operand.  This allows unnamed signals to be in
	the sets `env' attempts to manipulate when a --*-signal option is used
	with no argument, and kill(1) and timeout(1) to send such unnamed
	signals.

	* src/operand2sig.c (operand2sig): Drop signame argument, accept all
	signal numbers <= SIGNUM_BOUND.  All callers updated.
	* src/env.c (parse_signal_action_params, reset_signal_handlers)
	(parse_block_signal_params, set_signal_proc_mask)
	(list_signal_handling): Accept all signal numbers <= SIGNUM_BOUND,
	use SIG%d for printing if necessary.
	* src/kill.c (list_signals, main): Likewise.
	(send_signals): Check errno from kill(3) for bad signo.
	* src/timeout.c (main): Update operand2sig call.
	* tests/misc/kill.sh: Test listing all signal numbers.
	* NEWS: Mention the improvement.

2024-03-13  Pádraig Brady  <P@draigBrady.com>

	build: add caching for involved configure checks
	* configure.ac: Wrap the following with AC_CACHE_VAL,
	so that they can be cached / overridden.  We use
	the "utils_cv_" prefix as they're coreutils specific overrides.
	utils_cv_avx2_intrinsic_exists,
	utils_cv_brain_16_bit_supported,
	utils_cv_ieee_16_bit_supported,
	utils_cv_pclmul_intrinsic_exists,
	utils_cv_stdbuf_supported.

2024-03-13  Grisha Levit  <grishalevit@gmail.com>

	build: strengthen 16 bit float support checks
	Recent clang provides __bf16 on aarch64 but it is broken.

	If built with -O0, the conversion is wrong:

	    $ printf '\x3F\x80' | od --end=big -An -tfB | tr -d ' '
	    1.875

	If built with -O1 or higher, compilation fails:

	    fatal error: error in backend:
	    Cannot select: 0xb400007a58d29780: f32 = fp_extend 0xb40000...
	    0xb40000...: bf16,ch = CopyFromReg 0xb40000..., Register:bf16 %13
	    0xb40000...: bf16 = Register %13
	    In function: print_bfloat

	The latter issue does not cause the existing configure test to fail
	because the promotion is optimized out.

	* configure.ac: Ensure 16 bit float promotion code does not get
	optimized out, and produces an expected result.

2024-03-12  Collin Funk  <collin.funk1@gmail.com>

	maint: prefer minmax.h instead of defining our own
	* src/comm.c (min): Remove.
	(compare_files): Use MIN which is referenced by system.h.

2024-03-12  Ville Skyttä  <ville.skytta@iki.fi>

	dircolors: add more archive extensions
	* src/dircolors.hin: Add .apk (Alpine Linux/Android package); .drpm
	(delta rpm); .egg, .pyz, and .whl (Python related); and .udeb (form of
	.deb).

2024-03-12  Collin Funk  <collin.funk1@gmail.com>

	doc: add basic documentation for 'pinky'
	* doc/coreutils.texi: Add 'pinky' under 'who'.

	timeout: fix narrow race in failing to kill processes
	* src/timeout.c (main): Block cleanup signals earlier so that cleanup()
	is not runnable until monitored_pid is in a deterministic state.
	This ensures we always send a termination signal to the child
	once it's forked.
	* NEWS: Mention the bug fix.
	Reported at https://github.com/coreutils/coreutils/issues/82

2024-03-11  Pádraig Brady  <P@draigBrady.com>

	timeout: fix race where we might kill arbitrary processes
	* src/timeout.c (cleanup): Handle the case where monitored_pid
	might be -1, which could happen if a signal was received
	immediately after a failed fork() call.  In that case it would
	send the termination signal to all processes that the timeout
	process has permission to send signals too.
	* NEWS: Mention the bug fix.

	cp: add --keep-directory-symlink option
	When recursively copying files into OS trees, it often happens that
	some subdirectory of the source directory is a symlink in the target
	directory. Currently, cp will fail in that scenario with the error:

	"cannot overwrite non-directory %s with directory %s"

	However, we'd like cp in this scenario to follow the destination
	directory symlink and copy the files into the symlinked directory
	instead. Let's support this by adding a new option
	--keep-directory-symlink that makes cp follow destination directory
	symlinks.

	We name the option --keep-directory-symlink to keep consistent with
	tar which has the same option with the same effect.

	* doc/coreutils.texi (cp invocation): Describe the new option.
	* src/copy.h: Add the new setting.
	* src/copy.h: Adjust to follow symlinks if setting enabled.
	* src/cp.c (usage): Describe the new option.
	(main): Accept the new option.
	* tests/cp/keep-directory-symlink.sh: A new test.
	* tests/local.mk: Reference the new test.
