In C, strchr(3) returns a char*, whereas C++ defines two overloads:
* const char *strchr(const char*, int)
* char *strchr(char*, int)
Building fdt.cc (with the WITHOUT_GPL_DTC knob set) with libc++ 3.9.0 (imported
in r309124) was failing because libc++ r260377 added the first overload to
string.h, leading to failures such as:
fdt.cc:1638:8: error: cannot initialize a variable of type 'char *' with an
rvalue of type 'const char *'
Just define val as a const char* to fix it.

If set it installs LLD as /usr/bin/ld. LLD (as of version 3.9) is not
capable of linking the world and kernel, but can self-host and link many
substantial applications. GNU ld continues to be used for the world and
kernel build, regardless of how this knob is set.
It is on by default for arm64, and off for all other CPU architectures.

sendfile_swapin() loop works this way:
- Find first invalid page in the request.
- Do vm_pager_has_page() and get count of pages, that can be taken in
single I/O.
- Trim valid pages from the end of the request.
- Cycle through the request and substitute to bogus_page all valid
pages that are in the middle of the request.
- After I/O launched (pager copies array of pages into buf(9), it
is important to restore proper page pointers with help vm_page_lookup().
Count bogus pages used and report them in sendfile stats.
An example problem case is 163.1.0.0 (University of Oxford)
which is in an APNIC ERX address range. Previously we assumed
that ARIN has the correct information for all ERX allocations,
but in this case ARIN refers back to APNIC, rather than referring
to RIPE. This caused whois to loop.
Whois will no longer loop back and forth forever between two RIRs
that don't have an answer, but instead try the other RIRs in turn.
As Jean-Sébastien notes, fold(1) requires handling argv-supplied files. That
will require a slightly more sophisticated approach.

The previous calculation used an approximation which was only valid in
cases where the means being compared were similar; this resulted in very
odd claims being made, e.g. that 0 +/- 0 is a difference of -100% +/- 1%
from 100 +/- 1.
The new calculation scales sample standard deviations by the means, and
yields approximately correct percentage difference bounds providing that
the reference population is bounded away from zero. (In the case where
the values being compared are not sufficiently bounded away from zero,
the distribution of ratios becomes much harder to calculate, and is not
likely to be useful anyway.)
Note that when ministat is used for its intended purpose of determining
whether two samples are statistically different, this change is unlikely
to have any noticeable effect; in such cases the means will be similar
enough that the correction applied here will be minimal.
In r297602, which included a __FreeBSD_version bump to 1100105, we changed
sed 'i' and 'a' from discarding whitespaces to conform with what GNU and
sysvish sed do.
There are arguments in favor of keeping the old behavior but the new
behavior is also useful for migration purposes. It seems important to at
least consider the case of developers depending on the previous behavior,
so add a CFLAG to enable the old behaviour.

UUIDs are not portable.
o Move mkimg_uuid() to a new file and merge both gpt_uuid_enc()
and vhd_uuid_enc() into a single mkimg_uuid_enc() that lives
in the same file.
o Move the OS-specific implementation of generating a UUID to
osdep_uuidgen() and provide the implementations for FreeBSD,
macOS and Linux.
o Expect the partitioning scheme headers to be found by having
a search to the directory in which the headers live. This
avoids conflicts on non-FreeBSD machines.
Restructure this script so that it generates a header of tables instead
of a source file. The tables are included in a flags.c source file which
provides functions to decode various system call arguments.
For functions that decode an enumeration, the function returns a pointer
to a string for known values and NULL for unknown values.
For functions that do more complex decoding (typically of a bitmask), the
function accepts a pointer to a FILE object (open_memstream() can be used
as a string builder) to which decoded values are written. If the
function operates on a bitmask, the function returns true if any bits
were decoded or false if the entire value was valid. Additionally, the
third argument accepts a pointer to a value to which any undecoded bits
are stored. This pointer can be NULL if the caller doesn't care about
remaining bits.
Convert kdump over to using decoder functions from libsysdecode instead of
mksubr. truss also uses decoders from libsysdecode instead of private
lookup tables, though lookup tables for objects not decoded by kdump remain
in truss for now. Eventually most of these tables should move into
libsysdecode as the automated table generation approach from mksubr is
less stale than the static tables in truss.
Some changes have been made to truss and kdump output:
- The flags passed to open() are now properly decoded in that one of
O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded
mask.
- Optional arguments to open(), openat(), and fcntl() are only printed
in kdump if they exist (e.g. the mode is only printed for open() if
O_CREAT is set in the flags).
- Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int.
- Include all procctl() commands.
- Correctly decode pipe2() flags in truss by not assuming full
open()-like flags with O_RDONLY, etc.
- Decode file flags passed to *chflags() as file flags (UF_* and SF_*)
rather than as a file mode.
- Fix decoding of quotactl() commands by splitting out the two command
components instead of assuming the raw command value matches the
primary command component.
In addition, truss and kdump now build without triggering any warnings.
All of the sysdecode manpages now include the required headers in the
synopsis.

I had originally suspected the parsing of ctype definition files as being
the source of the ctype flag mis-definitions, but it wasn't. In the
process, I simplified the cc_list parsing so I'm committing the no-impact
improvement separately. It removes some parsing redundancies and
won't parse partial range definitions anymore.

This commit is from John Marino in dragonfly with the following commit log:
====
This was a CTYPE encoding error involving consecutive points of the same
ctype. It was reported by myself to Illumos over a year ago but I was
unsure if it was only happening on BSD. Given the cause, the bug is also
present on Illumos.
Basically, if consecutive points were of the exact same ctype, they would
be defined as a range regardless. For example, all of these would be
considered equivalent:
<A> ... <C>, <H> (converts to <A> .. <H>)
<A>, <B>, <H> (converts to <A> .. <H>)
<A>, <J> ... <H> (converts to <A> .. <H>)
So all the points that shouldn't have been defined got "bridged" by the
extreme points.
The effects were recently reported to FreeBSD on PR 213013. There are
countless places were the ctype flags are misdefined, so this is a major
fix that has to be MFC'd.

Enter Capsicum capability sandbox pretty early in this setuid program.
Some minor modifications were needed to cache directory fds and use
relative lookups.
Rights restriction of the stdio descriptors is unfortunately pretty messy
because we need an ioctl capability not present in the current libcapsicum
helpers (FIODGNAME).
