This flag is used in field 'cr_flags', which is never directly visible
outside the kernel. That field is however exported through 'struct
kinfo_proc' objects (field 'ki_cr_flags'), either from the kernel via
sysctls or from libkvm, and is supposed to contain exported flags
prefixed with KI_CRF_ (currently, KI_CRF_CAPABILITY_MODE and
KI_CRF_GRP_OVERFLOW, this second one being a purely userland one
signaling overflow of 'ki_groups').
Make sure that KI_CRF_CAPABILITY_MODE is the flag actually exported and
tested by userland programs, and hide the internal CRED_FLAG_CAPMODE.
As both flags are currently defined to the same value, this doesn't
change the KBI, but of course does change the KPI. A code search via
GitHub and Google fortunately doesn't reveal any outside uses for
CRED_FLAG_CAPMODE.
While here, move assignment of 'ki_uid' to a more logical place in
kvm_proclist(), and definition of XU_NGROUPS as well in 'sys/ucred.h'
(no functional/interface changes intended).

The error may be due to an error while writing, but it's more helpful to
report what we were trying to from rather than "stdout" for these
errors. Noticed because of what happens now when `cat` gets an EISDIR
for reading from a dirfd:
kevans@ifrit:~$ cat /etc
cat: stdout: Is a directory
which, after this change, becomes:

Some sh tests use ktrace to see whether a particular file, specified in

Use ktrace to only log name lookups, to avoid such false matches.

The intended value is:
-offset indent
If there's any typo such that the value doesn't match the pre-defined
strings, then the offset is the same width as the value. So by chance,
"-offset -ident" ended up being a standard-width indent (since the
default indent is 6 chars, and "-ident" also has 6 chars), whereas
"-offset -indent" had a longer indent, and "-offset ident" had a shorter
one.

Pax can sometimes loop forever. For example:
$ mkdir -p /tmp/src/foo/bar
$ rm -rf /tmp/dst ; mkdir -p /tmp/dst
$ cd /tmp/src
$ echo 'foo/bar/' | /bin/pax -r -w -d -pe "/tmp/dst"
<looping infinitely>
Here, pax(1) infinitely deletes and re-creates /tmp/dst/foo/bar/.
The problem is that chk_path() (bin/pax/file_subs.c), called from
node_creat() also creates the leaf directory when a trailing '/' appears
in the directory name to create. When the execution goes back from
chk_path() to node_creat(), the function still cannot create the leaf
directory (it has been created by chk_path()), so it unlinks it and
calls node_creat() again. The function re-creates it, and so on...
In node_creat() detect trailing slashes and not create a leaf directory,
but only intermediate ones.

I just noticed a slight issue with the '-D' option. Basically,
I accidentally typed something along the lines of:
ps -Dboth-p303
I.E. missing out the "space". Instead of giving an error, it behaved as
if I'd just typed "ps".
Looking at bin/ps/ps.c, where the -D option is parsed, it doesn't
error-out if there is no valid match.
This commit fixes the bug.

This patch introduces support for a conversion specification for
nanoseconds.
The format of %N is meant to be compatible with that of GNU date.
The nanoseconds conversion specification is implemented directly in
date(1) instead of libc (in strftime(3)) to avoid introducing
non-standard functions to libc at this time and modifying struct tm.
Apart from introducing the nanoseconds conversion specification, this
patch brings the following changes:
- The "ns" format for ISO 8061 dates is now unlocked. E.g., date -Ins
prints:
2024-04-22T12:20:28,763742224+02:00
- The -r flag when fed a file is now aware of the nanosecond part of the last
modification time.
- date(1) is now able to set the time with nanosecond precision. It is
not possible as of now to do that by specifying nanoseconds directly
via the command-line arguments. Instead, the -r flag can be used.
- date(1) is now using the clock_gettime(3) family of functions instead
of ctime(3) family of functions where possible.

compiler doesn't support it. The sys/cdefs.h has had __unreachable for
9 years (commit 732b31de5d). It expands
to the builtin if it is available. In the rare case that it is
unsupported it expands to a null statement so compilation does not

Historically, BSD cp has followed symbolic links in the destination
when copying recursively, while GNU cp has not. POSIX is somewhat
vague on the topic, but both interpretations are within bounds. In
33ad990ce9, cp was changed to apply the same logic for symbolic
links in the destination as for symbolic links in the source: follow
if not recursing (which is moot, as this situation can only arise
while recursing) or if the `-L` option was given. There is no support
for this in POSIX. We can either switch back, or go all the way.
Having carefully weighed the kind of trouble you can run into by
following unexpected symlinks up against the kind of trouble you can
run into by not following symlinks you expected to follow, we choose
to go all the way.
Note that this means we need to stat the destination twice: once,
following links, to check if it is or references the same file as the
source, and a second time, not following links, to set the dne flag
and determine the destination's type.
While here, remove a needless complication in the dne logic. We don't
need to explicitly reject overwriting a directory with a non-directory,
because it will fail anyway.
Finally, add test cases for copying a directory to a symlink and
overwriting a directory with a non-directory.
