The program reads oldsize bytes from oldfile, and proceeds to initialize
a suffix array of oldsize elements using divsufsort(). As per the
function's API [1], array indices 0 through n-1 are initialized.
Later, search() is called, but with index bounds [0, n]. Depending on
the contents of the malloc'd buffer, accessing this uninitialized index
at the end of can result in a segmentation fault. Fix this by passing
oldsize-1 to search(), limiting the search bounds to [0, n-1].
This bug is a result of r303285, which introduced divsufsort() as an
alternate suffix sorting function to the existing qsufsort(). It seems
that qsufsort() did initialize the final empty element, meaning it could
be safely accessed. This difference in the implementations was missed at
the time.

The previous behavior was to support nested #ifdef and #ifndef, but to
return to unconditional parsing after the next #endif, independently of
the number of previously parsed conditions.
E.g. after "#ifdef A / #ifdef B / #endif" the following lines were
unconditially parsed again, independently of A and/or B being defined.
The new behavior is to count the level of false conditions and to only
restart parsing of calendar entries when the corresponding number of
#endif tokens have been seen.
In addition to the above, an #else directive has been added, to toggle
between parsing and ignoring of the following lines.
No validation of the correct use of the condition directives is made.
#endif without prior #define or #ifndef is ignored and #else toggles
between parsing and skipping of entries.
The MFC period has been set to 1 month to allow for a review of the
changes and for a discussion, whether these modifications should not

According to git blame the trymmap() function was added in 1996 to skip
mmap() calls for NFS file systems. However, nowadays mmap() should be
perfectly safe even on NFS. Importantly, onl ufs and cd9660 file systems
were whitelisted so we don't use mmap() on ZFS. It also prevents the use
of mmap() when bootstrapping from macOS/Linux since on those systems the
trymmap() function was always returning zero due to the missing MFSNAMELEN
define.
This change keeps the trymmap() function but changes it to check whether
using mmap() can reduce the number of system calls that are required.
Using mmap() only reduces the number of system calls if we need multiple read()
syscalls, i.e. if the file size is > MAXBSIZE. However, mmap() is more expensive
than read() so this sets the threshold at 4 fewer syscalls. Additionally, for
larger file size mmap() can significantly increase the number of page faults,
so avoid it in that case.
It's unclear whether using mmap() is ever faster than a read with an appropriate
buffer size, but this change at least removes two unnecessary system calls
for every file that is installed.

This change is based on the nexthop objects landed in D24232.
The change introduces the concept of nexthop groups.
Each group contains the collection of nexthops with their
relative weights and a dataplane-optimized structure to enable
efficient nexthop selection.
Simular to the nexthops, nexthop groups are immutable. Dataplane part
gets compiled during group creation and is basically an array of
nexthop pointers, compiled w.r.t their weights.
With this change, `rt_nhop` field of `struct rtentry` contains either
nexthop or nexthop group. They are distinguished by the presense of
NHF_MULTIPATH flag.
All dataplane lookup functions returns pointer to the nexthop object,
leaving nexhop groups details inside routing subsystem.
User-visible changes:
The change is intended to be backward-compatible: all non-mpath operations
should work as before with ROUTE_MPATH and net.route.multipath=1.
All routes now comes with weight, default weight is 1, maximum is 2^24-1.
Current maximum multipath group width is statically set to 64.
This will become sysctl-tunable in the followup changes.

* Recompile kernel with ROUTE_MPATH
* set net.route.multipath to 1

By default, lockf(1) opens its lock file O_RDONLY|O_EXLOCK. On NFS, if the
file already exists, this is split into opening the file read-only and then
requesting an exclusive lock -- and the second step fails because NFS does
not permit exclusive locking on files which are opened read-only.
The new -w option changes the open flags to O_WRONLY|O_EXLOCK, allowing it
to work on NFS -- at the cost of not working if the file cannot be opened
for writing.
(Whether the traditional BSD behaviour of allowing exclusive locks to be
obtained on a file which cannot be opened for writing is a good idea is
perhaps questionable since it may allow less-privileged users to perform
a local denial of service; however this behaviour has been present for a
long time and changing it now seems like it would cause problems.)

The most awkward bit in this patch is the bootstrapping of m4:
We can't simply use the host version of m4 since that is not compatible
with the flags passed by lex (at least on macOS, possibly also on Linux).
Therefore we need to bootstrap m4, but lex needs m4 to build and m4 also
depends on lex (which needs m4 to generate any files). To work around this
cyclic dependency we can build a bootstrap version of m4 (with pre-generated
files) then use that to build the real m4.
This patch also changes the xz/unxz/dd tools to always use the host version
since the version in the source tree cannot easily be bootstrapped on macOS
or Linux.

Add small example section showing general use and -d and -h flags
Approved by: manpages (bcr@)
Differential Revision: https://reviews.freebsd.org/D26172
Every version of patch since the first one posted to mod.sources in 1985 have
included a heuristic for coping with the state of email messaging at the
time. This heuristic would add up to 4 blank lines to a patch if it thought it
needed it. The trouble is, though this causes at least one bug.
The bug in my case is that if you have a context diff whose last hunk only
deletes 3 or fewer lines, then if you try to reverse apply it with -R, it will
fail. The reason for this is the heuristic builds an internal representation
that includes those blank lines. However, it should really replicate the lines
from the pattern lines line it would any other time, not assume they are blank
lines. Removing this heuristic will prevent patch from misapplying the lines
removed after applying a 'fuzz' factor to the previous blank line in the file. I
believe this will only affect 'new-style' 4.3BSD context diffs and not the
older-style 4.2BSD diffs and plain, non-context diffs. It won't affect any of
the newer formats, since they don't use the 'omitted' construct in the same way.
Since this heuristic was put into patch at a time when email / etc ate trailing
white space on a regular basis, and since it's clear that this heuristic is the
wrong thing to do at least some of the time, it's better to remove it
entirely. It's not been needed for maybe 20 years since patch files are not
usually corrupted. If there are a small number of patch files that would benefit
from this corruption fixing, those already-currupt patches can be fixed by the
addition of blank lines. I'd wager that no one will ever come to me with an
example of a once-working patch file that breaks with this change. However, I
have 2 patches from the first 195 patches to 2.11BSD that are affected by this
bug, suggesting that the relative frequency of the issue has changed
signficantly since the original heuristic was put into place.

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

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
are compatible with those on the target system which is not necessarily true.
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"
locale headers for printf(), etc., but we also want to access the target
systems's internal locale structures.

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.
Take a look at https://reviews.freebsd.org/D25551 for details
and efficiency numbers (in short: upto 32% gained for installword).

This version fixes a regression with regard to tradtional behavior of the
non-standard FreeBSD option "-e". In the previous version "-e quit" caused
bc to exit before any computations had been performed, since all -e option
parameters were concatenated and parsed as a whole, with quit causing the
program to exit as soon as it was parsed. This version parses and executes
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
after the import to contrib. Instead the contents of contrib/bc has been
removed and the new version is copied over unchanged from vendor/bc/dist.

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.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.
Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
