* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME
as a parameter, so that consistent references are made to online docs
and texinfo nodes, when a --program-prefix is in place. Note the
man pages don't need this fix as they're generated before the program
prefix is used.
* NEWS: Mention the improvements in references to online documentation.

Since commit v8.22-94-g99960ee, chroot(1) skips the chroot(2) syscall
for "/" arguments (and synonyms). The problem is that it also skips
the following chdir("/") call in that case. The latter breaks existing
scripts which expect "/" to be the working directory inside the chroot.
While the first part of the change - i.e., skipping chroot("/") - is
okay for consistency with systems where it might succeed for a non-root
user, the second part might be malicious, e.g.
cd /home/user && chroot '/' bin/foo
In the "best" case, chroot(1) could not execute 'bin/foo' with ENOENT,
but in the worst case, chroot(1) would execute '/home/user/bin/foo' in
the case that exists - instead of '/bin/foo'.
Revert that second part of the patch, i.e., perform the chdir("/)
in the common case again - unless the new --skip-chdir option is
specified. Restrict this new option to the case of "/" arguments.
* src/chroot.c (SKIP_CHDIR): Add enum.
(long_opts): Add entry for the new --skip-chdir option.
(usage): Add --skip-chdir option, and while at it, move the other
to options into alphabetical order.
(main): Accept the above new option, allowing it only in the case
when NEWROOT is the old "/".
Move down the chdir() call after the if-clause to ensure it is
run in any case - unless --skip-chdir is specified.
Add a 'newroot' variable for the new root directory as it is used
in a couple of places now.
* tests/misc/chroot-fail.sh: Invert the last tests which check the
working directory of the execvp()ed program when a "/"-like
argument was passed: now expect it to be "/" - unless --skip-chdir
is given.

Document that chroot(1) usually calls chdir("/") unless the new
--skip-chdir option is specified. Sort options.

This didn't seem to cause any invalid operation on GNU/Linux at least,
but depending on the implementation, mutex deadlocks could occur.
For example this might be the cause of lockups seen on Solaris:
http://lists.gnu.org/archive/html/coreutils/2013-03/msg00048.html
This was identified with valgrind 3.9.0 with this setup:
seq 200000 > file.sort
valgrind --tool=drd src/sort file.sort -o file.sort
With that, valgrind would _intermittently_ report the following:
Destroying locked mutex: mutex 0x5419548, recursion count 1, owner 2.

Add the --enable-single-binary option to the configure file.
When enabled, this option builds a single binary file containing
the selected tools. Which tool gets executed depends on the value
of argv[0] which can be set implicitly through symlinks to the
single program.
This setup reduces significantly the size of a complete coreutils
install, since code from lib/libcoreutils.a is not duplicated in
every one of the more than 100 binaries. Runtime overhead is
increased due to more dynamic libraries being loaded, and extra
initialization being performed for all utils. Also initially
a larger binary is loaded from storage, though this is usually
alleviated due to caching and lazy mmaping of unused blocks,
and in fact the single binary should have better caching
characteristics.
Comparing the size of the individual versus single binary on x86_64:
$ cd src
$ size coreutils
$ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
text data bss dec hex filename
1097416 5388 88432 1191236 122d44 src/coreutils
4901010 124964 163768 5189742 4f306e (TOTALS)
Storage requirements are reduced similarly:
$ cd src
$ du -h coreutils
$ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
1.2M coreutils
5.3M total
When installing, the makefile will create either symlinks or
shebangs based on the --enable-single-binary setting, for
each configured tool. In this way, all the tools are still
callable individually, but they are all implemented by the same
"coreutils" binary installed on the same directory.

commits v8.20-98-g51ce0bf and v8.20-99-gd302aed changed cut(1)
to process each line independently and thus promptly output
each line without buffering. As part of those changes we removed
the special handling of --delimiter=$'\n' --fields=... which
could be used to select arbitrary (ranges of) lines, so as to
simplify and optimize the implementation while also matching the
behavior of different cut(1) implementations.
However that GNU behavior was in place for a long time, and
could be useful in certain cases like making a separated list like
`seq 10 | cut -f1- -d$'\n' --output-delimiter=,` although other tools
like head(1) and paste(1) are more suited to this operation.
This patch reinstates that functionality but restricts the
"line behind" buffering behavior to only the -d$'\n' case.
We also fix the following related edge case to be more consistent:
before> printf "\n" | cut -s -d$'\n' -f1- | wc -l
2
before> printf "\n" | cut -d$'\n' -f1- | wc -l

The device name reported for a particular mount entry
may no longer be valid if the mount point was subsequently
mounted on a different device. Therefore honor the order

It's dangerous and confusing to leave root's supplemental
groups in place when specifying other users with --userspec.
In the edge case that that is desired one can explicitly
specify --groups.
Also we implicitly set the system defined supplemental groups
for a user. The existing mechanism where supplemental groups
needed to be explicitly specified is confusing and not general
when the lookup needs to be done within the chroot.
Also we extend the --groups syntax slightly to allow clearing
the set of supplementary groups using --groups=''.
* src/chroot.c (setgroups): On systems without supplemental groups,
clearing then is a noop and so should return success.
(main): Lookup the primary GID with getpwuid() when just a numeric
uid is specified, and also infer the USERNAME from this call,
needed when we're later looking up the supplemental groups for a user.
Support clearing supplemental groups, either implicitly for
unknown users, or explicitly when --groups='' is specified.
* tests/misc/chroot-credentials.sh: Various new test cases
* doc/coreutils.texi (chroot invocation): Adjust for the new behavior.
* NEWS: Mention the change in behavior.

This allows chroot to be used as a light weight tool
to change user identification for a command,
while not changing the current working directory.
It also makes `chroot / true` consistently succeed on
all platforms for non root users.
* src/chroot.c (main): If the same root is specified. i.e. '/'
then don't change the current working directory, and avoid the
overhead of the other redundant calls.
* tests/misc/chroot-fail.sh: Remove failure guard previously
needed on some systems. Also add an explicit case to ensure
we don't change directory.
* NEWS: Mention the change in behavior.

* src/df.c (filter_mountlist): Remove the constraint that
a '/' needs to be in the device name for a mount entry to
be considered for deduplication. Virtual file systems also
have storage associated with them (like tmpfs for example),
and thus need to be deduplicated since they will be shown
in the default df output and subject to --total processing also.
* test/df/skip-duplicates.sh: Add a test to ensure we deduplicate
all entries, even for virtual file systems. Also avoid possible
length operations on many remote file systems in the initial
check of df operation. Also avoid the assumption that "/root"
is on the same file system as "/".

The initial report and high level analysis were from Jim Meyering...
"The underlying problem is that swallow_file_in_memory()
is setting the contents of the global text_buffer for the first file,
then updating it (clobbering old value) for the second file.
Yet, some pointers to the initial buffer have been squirreled away
and later, one of them (keyafter) is presumed to point into
the new "text_buffer", which it does not. The subsequent
SKIP_WHITE_BACKWARDS use backs up "cursor" and goes out of bounds."
* src/ptx.c (text_buffers): Maintain references for the limits of each
buffer corresponding to each file, rather than just the last processed.

to OFF_T_MAX in the edge case where we do overflow.
* NEWS: Mention the shred improvements from recent changes.
* tests/misc/shred-passes.sh: Adjust as we no longer
write a BLKSIZE of data for empty files.

This removes an unportable assumption that if lseek succeeds, the
file is capable of seeking. See: http://bugs.gnu.org/17145
* src/head.c (elseek): New function, for consistency in reporting
lseek failures.
(elide_tail_bytes_file, elide_tail_lines_seekable)
(elide_tail_lines_file, head_lines, head): Use it.
(elide_tail_bytes_file, elide_tail_lines_file):
New args CURRENT_POS and SIZE. All uses changed. Don't bother
invoking lseek, since we know the file's pos and size now.
(elide_tail_bytes_file): Change a local from uintmax_t to off_t,
since it fits.
(head): Use lseek only on regular files, since its behavior on
unseekable devices is implementation-defined.
* NEWS: Document this.

* src/head.c (elide_tail_bytes_file): Fix typo in lseek invocation.
* tests/misc/head-c.sh: Add test for this bug.
* NEWS: Document this.

* src/ptx.c (main): Add a 'break' after the --format handling case.
Otherwise it would fall through into the usage case.
* tests/misc/ptx.pl: Add test cases for --format=tex and --format=roff.
* NEWS (Bug fixes): Mention the fix.
Bug introduced in 1999-04-04 commit, SH-UTILS-1_16f-269-gd815c15.
Spotted by coverity (MISSING_BREAK).

Input buffering is best avoided because it introduces
delayed processing of output for intermittent input,
especially when the output size is less than that of
the input buffer. This is significant when output
is being further processed which could happen if split
is writing to precreated fifos, or through --filter.
If input is arriving quickly from a pipe then this will
already be buffered before we read it, so fast arriving
input shouldn't be a performance issue.
* src/split.c (lines_split, lines_bytes_split, bytes_split,
lines_chunk_split, bytes_chunk_extract): s/full_read/safe_read/.
* THANKS.in: Mention the reporter.
* NEWS: Mention the improvement.

For files with "special" bits set, we would stat the relative
file name in the wrong directory, giving an erroneous ENOENT diagnostic.
This issue was introduced with commit v5.92-653-gc1994c1
which changed fts to not change directory on traversal.
* src/chmod.c (mode_changed): Use fts->fts_cwd_fd with fstatat rather
than stat. All callers changed.
* tests/chmod/c-option.sh: Add a test case.
* NEWS: Mention the fix.

Prior to this change, "ln -sr '' F" would segfault, attempting
to read path2[1] in relpath.c's path_common_prefix function.
This problem arises whenever canonicalize_filename_mode returns
NULL.
* src/ln.c (convert_abs_rel): Call relpath only when
both canonicalize_filename_mode calls return non-NULL.
* tests/ln/relative.sh: Add a test to trigger this failure.
* THANKS.in: List reporter's name/address.
* NEWS (Bug fixes): Mention it.

- Support arbitrary numbers in --groups, consistent with
what is already done for --userspec
- Avoid look-ups entirely for --groups items with a leading '+'
- Support names that are actually numbers in --groups
- Ignore an empty --groups="" option for consistency with --userspec
- Look up both inside and outside the chroot with inside taking
precedence. The look-up outside may load required libraries
to complete the look-up inside the chroot. This can happen for
example with a 32 bit chroot on a 64 bit system, where the
32 bit NSS plugins within the chroot fail to load.
* src/chroot.c (parse_additional_groups): A new function refactored
from set_addition_groups(), to just do the parsing. The actual
setgroups() call is separated out for calling from the chroot later.
(main): Call parse_user_spec() and parse_additional_groups()
both outside and inside the chroot for the reasons outlined above.
* tests/misc/chroot-credentials.sh: Ensure arbitrary numeric IDs
can be specified without causing look-up errors.
* NEWS: Mention the improvements.
* THANKS.in: Add Norihiro Kamae who initially reported the issue
with a proposed patch.
Also thanks to Dmitry V. Levin for his diagnosis and sample patch.

* NEWS: Mention the fix.

* src/shuf.c (main): s/No/no/, introduced by commit v8.22-25-g9f60f37.

Problem reported by valiant xiao in <http://bugs.gnu.org/16855>.
* NEWS: Document this.
* src/shuf.c (main): With -r, report an error if the input is empty.
* tests/misc/shuf.sh: Test for the bug.

* src/head.c (elide_tail_lines_pipe): Just output all input in
this case to avoid the issue and also avoid redundant '\n' processing.
(elide_tail_lines_seekable): Likewise.
* tests/misc/head-elide-tail.pl: Add tests for no '\n' at EOF.
* NEWS: Mention the fix.

taking "little" and "big" as parameters.
(usage): Describe the new option.
(PRINT_FIELDS): Adjust to swap bytes if required.

the byte swapping operations for hex (ints) and floats
for all sizes between 1 and 16 inclusive.
* test/local.mk: Reference the new test.
* doc/coreutils.texi (od invocation): Describe the new option.

set of errors we handle.
* tests/ln/sf-1.sh: Add test cases for the newly handled errors.

* src/selinux.c (restorecon_private): On ArchLinux the
`fakeroot cp -a file1 file2` command segfaulted due
to getfscreatecon() returning a NULL context.
So map this to the sometimes ignored ENODATA error,
rather than crashing.
* tests/cp/no-ctx.sh: Add a new test case.
* tests/local.mk: Reference the new test.
* NEWS: Mention the fix.

* src/copy.c (copy_internal): Use the global process context
to set the context of existing directories before they're populated.
This is more consistent with the new directory case, and fixes
a bug for existing directories where we erroneously set the
context to the last copied descendent, rather than to that of
the source directory itself.
* tests/cp/cp-a-selinux.sh: Add a test for this case.
* NEWS: Mention the fix.
* THANKS.in: Add reporter Michal Trunecka.
