My change to allow bootstrapping pwd_mkdb (r363992) resulted in i386 build
failures because the bootstrap header was being included in non-bootstrap chpass.
Dropping the no longer required pwd_mkdb include path from chpass fixes
the build, but to be certain that the failure doesn't get re-introduced,
I've also moved the bootstrap pwd.h into a subdirectory so that adding
-I${SRCTOP}/usr.sbin/pwd_mkdb doesn't pull it in.

libregex is incomplete, but it's a bit less buggy than the in-base
libgnuregex and mostly OK.
While here, rename -DIWTH_GNU -> -DWITH_GNU_COMPAT; the option implies
that we're compatible with the GNU counterpart, not that we're including GNU
anything.
The tests compare the command output (including of error cases) with the
expected output and exit code.
Not all tests are executed, since some expect to have a known good bc and
dc binary installed and compare results of large amounts of generated data
being processed by both versions to test for regressions.
This version omits the printing of a copyright header in interactive mode
and the dc command now exits after execution of the commands passed via -e
or -f instead of switching to interactive mode. To pass further commands
via STDIN when dc has been invoked with -e or -f, add "-f -" to the
parameter list.
r363679 is in-fact the future change referenced by the comment, helpfully
left and forgotten by kevans. Instead of just silently not matching, we
should now be erroring out with vigor.
It's currently unclear to me how this could have worked previously; \n here
is not a literal newline but actual '\' 'n', and was getting passed to the
underlying regex engine as such. regex(3) does not translate this to a
newline, and this became an error because we don't really allow escaping
of arbitrary ordinary characters anymore.
Run the pattern strings through printf to make sure we're dealing with real
newlines before passing them through to atf_check, which ultimately feeds
them directly to regcomp(3).
This fix is different than that will be needed for sed, in that this is the
proper way to inject newlines into search strings as long as regex(3)
won't combine \ + n as folks might expect.

The current localedef simply assumes that the locale headers on build system

It generally works on FreeBSD (as long as we don't change the locale headers),
but Linux and macOS provide completely different locale headers.
This change adds new bootstrap headers that namespace certain xlocale
structures defined or used by in the headers that localdef needs.
This is required since system headers *must* be able to include the "real"

Currently, "install -s -S" behaviour is inefficient for upgrade.
First it finds that destination file already exists and copies
source file to temporary file. Then it calls strip(1)
with name of temporary file as single agrument and our strip(1) creates
another temporary file in the /tmp (or TMPDIR) making another copy
that is finally copied to DESTDIR third time.
Meantime, strip(1) has an option "-o dst" to specify destination
so install(1) is allowed to skip initial copying from obj to DESTDIR.
This change makes it do so.

This version fixes a regression with regard to tradtional behavior of the

bc to exit before any computations had been performed, since all -e option

commands passed with -e one by one and only exits after all prior commands
have been executed.
This commit is not a SVN merge, since the vendor import had been performed

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:
- They do not depend on external large number functions (i.e. no dependency
on OpenSSL or any other large number library)
- They implements all features found in GNU bc/dc (with the exception of
the forking of sub-processes, which the author of this version considers
as a security issue).
- They are significantly faster than the current code in base (more than
2 orders of magnitude in some of my tests, e.g. for 12345^100000).
- They should be fully compatible with all features and the behavior of the
current implementations in FreeBSD (not formally verified).
- They support POSIX message catalogs and come with localized messages in
Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
and Russian.
- They offer very detailed man-pages that provide far more information than
the current ones.

Sort(1)'s radixsort implementation was broken for multibyte LC_CTYPEs in at

* In actual radix sort, it would only bucket the least significant
byte from each wchar, ignoring the 24 most-significant bits of each
unicode character.
* In degenerate cases / "fast paths," it would fall back to another
sorting algorithm (default: mergesort) with a bogus comparator
offset. The string comparison functions in sort(1) take an offset
in units of the operating character size. However, radixsort was
passing an offset in units of bytes. The byte offset must be
divided by sizeof(wchar_t).
This revision addresses both discovered issues.

Changes since 20181221 are mostly portability related
hence the large gap in versions imported.
There are however some bug fixes, and a rework of filemon handling.
In NetBSD make/filemon/filemon_ktrace.c allows use of fktrace
and elimination of filemon(4) which has not had the TLC it needs.
FreeBSD filemon(4) is in much better shape, so bmake/filemon/filemon_dev.c
allows use of that, with a bit less overhead than the ktrace model.
Summary of changes from ChangeLog
o str.c: empty string does not match % pattern

o var.c: import handling of old sysV style modifier using '%'
o str.c: refactor brk_string
o meta.c: meta_oodate, CHECK_VALID_META is too aggressive for CMD
a blank command is perfectly valid.
o meta.c: meta_oodate, check for corrupted meta file
earlier and more often.
* meta.c: meta_compat_parent check for USE_FILEMON
patch from Soeren Tempel
o meta.c: fix compat mode, need to call meta_job_output()
o job.c: extra fds for meta mode not needed if using filemon_dev
o meta.c: avoid passing NULL to filemon_*() when meta_needed()
returns FALSE.
o filemon/filemon_{dev,ktrace}.c: allow selection of
filemon implementation. filemon_dev.c uses the kernel module
while filemon_ktrace.c leverages the fktrace api available in
NetBSD. filemon_ktrace.c can hopefully form the basis for
adding support for other tracing mechanisms such as strace on
Linux.

This is the foundational change for the routing subsytem rearchitecture.
More details and goals are available in https://reviews.freebsd.org/D24141 .
This patch introduces concept of nexthop objects and new nexthop-based
routing KPI.
Nexthops are objects, containing all necessary information for performing
the packet output decision. Output interface, mtu, flags, gw address goes
there. For most of the cases, these objects will serve the same role as
the struct rtentry is currently serving.
Typically there will be low tens of such objects for the router even with
multiple BGP full-views, as these objects will be shared between routing
entries. This allows to store more information in the nexthop.
New KPI:
struct nhop_object *fib4_lookup(uint32_t fibnum, struct in_addr dst,
uint32_t scopeid, uint32_t flags, uint32_t flowid);
struct nhop_object *fib6_lookup(uint32_t fibnum, const struct in6_addr *dst6,
uint32_t scopeid, uint32_t flags, uint32_t flowid);
These 2 function are intended to replace all all flavours of
<in_|in6_>rtalloc[1]<_ign><_fib>, mpath functions and the previous
fib[46]-generation functions.
Upon successful lookup, they return nexthop object which is guaranteed to
exist within current NET_EPOCH. If longer lifetime is desired, one can
specify NHR_REF as a flag and get a referenced version of the nexthop.
Reference semantic closely resembles rtentry one, allowing sed-style conversion.
Additionally, another 2 functions are introduced to support uRPF functionality
inside variety of our firewalls. Their primary goal is to hide the multipath
implementation details inside the routing subsystem, greatly simplifying
firewalls implementation:
int fib4_lookup_urpf(uint32_t fibnum, struct in_addr dst, uint32_t scopeid,
uint32_t flags, const struct ifnet *src_if);
int fib6_lookup_urpf(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid,
uint32_t flags, const struct ifnet *src_if);
All functions have a separate scopeid argument, paving way to eliminating IPv6 scope
embedding and allowing to support IPv4 link-locals in the future.
Structure changes:
* rtentry gets new 'rt_nhop' pointer, slightly growing the overall size.
* rib_head gets new 'rnh_preadd' callback pointer, slightly growing overall sz.
Old KPI:
During the transition state old and new KPI will coexists. As there are another 4-5
decent-sized conversion patches, it will probably take a couple of weeks.
To support both KPIs, fields not required by the new KPI (most of rtentry) has to be
kept, resulting in the temporary size increase.
Once conversion is finished, rtentry will notably shrink.

--tabsize was previously listed as optional_argument, but didn't account for
the optionality of it in the argument handling. This is irrelevant -- the
manpage doesn't indicate that the argument is optional, and indeed there's
no clear interpretation of omitting the argument because there's no other
side effect of --tabsize.
The "malformed" argument part of the header on this message is simply
referring to usage like this:
% diff --tabsize 4 A B
With an optional_argument, the argument must be attached to the parameter
directly (e.g. --tabsize=4), so the argument is effectively NULL with the

r355992 added listing of NFSv4.2 procedure and operation counts.
This patch updates the nfsstat.1 man page to reflect that change.
This is a content change.
r355677 added NFSv4.2 support to the NFS client and server. It also updated
the nfsstats structure to keep counts for the new procedures (client) and
operations (server) added for NFSv4.2.
This patch updates the "-E" option of nfsstat so that it lists counts for
these new procedures and operations.
This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.
Updating the vendor area to match this layout is next.
- Move libxo.a build to subdirectory (lib/libxo/libxo/Makefile)

This adds a new -D/--all-repeats option to uniq(1), which outputs each copy
of any repeated lines (as opposed to a single copy of a repeated line). You
can specify a separator option to output a blank line before or after each
group of repeated lines. This adds compatibility with the GNU coreutils
version of uniq(1).
This change also re-groups the -c, -d, -D, -u options in the usage display
and man page to indicate that they are mutally exclusive of each other. This
matches the posix/opengroup definition of uniq(1) command line args. Note
that this change does NOT actually enforce the mutual exclusion in the code,
for now, it simply documents that the arguments should be considered
exclusive with each other.

This is both reasonable and a common GNUism that a lot of ported software
expects.
Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.
Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.
This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.
Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

Use RB_TREE to make some algorithms O(lg N) and O(N lg N) instead of O(N)
and O(N^2). Because N is typically small and the former linear array also has
great constant factors (as a property of CPU caching), this doesn't provide
material benefit most or all of the time.
While here, remove arbitrarily limit on number of macros understood.
Otherwise small quantities look nonsensical. For instance, when
swapping in a single page we would print "4096 In".

The igmp stats tend to print two lines of warning for an unexpected
version and length. Despite an invalid version and struct size it
continues to try to do something with the data. Do not try to parse
the remainder of the struct and error on warning.
Note the underlying issue of the data not being available properly
is still there and needs to be fixed seperately.

The code for "netstat -gs -f inet" failed if the kernel namelist did not
include the _mrtstat symbol. However, that symbol is not in a standard
kernel even with the ip_mroute module loaded, where the functionality is
available. It is also not in a kernel with MROUTING but also VIMAGE, as
there can be multiple sets of stats. However, when running the command
on a live system, the symbol is not used; a sysctl is used. Go ahead
and try the sysctl in any case, and complain that IPv4 MROUTING is not
present only if the sysctl fails with ENOENT. Also fail if _mrtstat is
not defined when running on a core file; netstat doesn't know about vnets,
so can only work if MROUTING was included, and VIMAGE was not.

We have a bad habit of duplicating contents of files that are sourced from
/dev/null and applied more than once... take the more sane (in most ways)
GNU route and complain if the file exists and offer reversal options.
This still falls short a little bit as selecting "don't reverse, apply
anyway" will still give you duplicated file contents. There's probably other
issues as well, but awareness is the first step to happiness.

This warning (comparing a pointer against a zero character literal
rather than NULL) has existed since GCC 7.1.0, and was recently added to
Clang trunk.
Almost all of these are harmless, except for fwcontrol's str2node, which
needs to both guard against dereferencing a NULL pointer (though in
practice it appears none of the callers will ever pass one in), as well
as ensure it doesn't parse the empty string as node 0 due to strtol's
awkward interface.

This uses the same logic as with the -s option, first validating the

X-MFC-With: r352818
In r334906, the -s option was changed to allow fractional times, but
this only functioned correctly for batch mode. In interactive mode, any
delay below 1.0 would get floored to zero. This would put top(1) into a
tight loop, which could be difficult to interrupt.
Fix this by storing the -s option value (after validation) into a struct
timeval, and using that struct consistently for delaying with select(2).
Next up is to allow interactive entry of a fractional delay value.

Add an atomic shm rename operation, similar in spirit to a file
rename. Atomically unlink an shm from a source path and link it to a
destination path. If an existing shm is linked at the destination
path, unlink it as part of the same atomic operation. The caller needs
the same permissions as shm_unlink to the shm being renamed, and the
same permissions for the shm at the destination which is being
unlinked, if it exists. If those fail, EACCES is returned, as with the
other shm_* syscalls.
truss support is included; audit support will come later.
This commit includes only the implementation; the sysent-generated

When an empty pattern is encountered in the pattern list, I had previously
broken bsdgrep to count that as a "match all" and ignore any other patterns
in the list. This commit rectifies that mistake, among others:
- The -v flag semantics were not quite right; lines matched should have been
counted differently based on whether the -v flag was set or not. procline
now definitively returns whether it's matched or not, and interpreting
that result has been kicked up a level.
- Empty patterns with the -x flag was broken similarly to empty patterns
with the -w flag. The former is a whole-line match and should be more
strict, only matching blank lines. No -x and no -w will will match the
empty string at the beginning of each line.
- The exit code with -L was broken, w.r.t. modern grep. Modern grap will
exit(0) if any file that didn't match was output, so our interpretation
was simply backwards. The new interpretation makes sense to me.
Tests updated and added to try and catch some of this.

The way jot(1) defaults missing arguments doesn't match the behaviour
described in the manpage, which states that with fewer than 3 arguments
missing values are supplied from left to right.
In fact, with one or two arguments, the last (s which is step size or seed)
defaults to 1 (or -1 if begin and end specify a descending range), and then
omitted arguments are set to default starting with the leftmost until three
arguments are available.
This is why `jot 2 1000` prints 1000 and 1001 instead of 1000 and 100.
