One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

These were only used on PDP-11 for two programs we don't ship,
and have been obsolete since the VAX days.
xstr never worked in the build.sh cross-build environment (22 years), or
parallel make environment (nearly 28 years), didn't work in the orignal 386bsd
import, and has never been needed in NetBSD as we don't have the older BSD
programs (pascal, pre-nvi ex) that needed mkstr/xstr on PDP-11.

New test case that reflects the fix in PR kern/57260. The majority of
work for this case itself was by riastradh@, who'd supplied the basis
for it in the ticket, and provided further guidance.

allow conditionally disabling the building of certain user space

There is not enough consensus that this is the right way and a few
people had strong objections, see source-changes-d@.

This was introduced two years ago when the getrandom/getentropy API
question was still open, and removed because the discussion was
ongoing. Now getentropy is more widely adopted and soon to be in
POSIX. So reintroduce the symbol into libc since we'll be keeping it
anyway. Discussion of details of the semantics, as interpreted by
NetBSD, is ongoing, but the symbol needs to get in before the
netbsd-10 branch. The draft POSIX text is
(https://www.opengroup.org/austin/docs/austin_1110.pdf):
SYNOPSIS
#include <unistd.h>
int getentropy(void *buffer, size_t length);
DESCRIPTION
The getentropy() function shall write length bytes of data
starting at the location pointed to by buffer. The output
shall be unpredictable high quality random data, generated by
a cryptographically secure pseudo-random number
generator. The maximum permitted value for the length
argument is given by the {GETENTROPY_MAX} symbolic constant
defined in <limits.h>.
RETURN VALUES
Upon successful completion, getentropy() shall return 0;
otherwise, -1 shall be retunred and errno set to indicate the
error.
ERRORS
The getentropy() function shall fail if:
[EINVAL] The value of length is greater than
{GETENTROPY_MAX}.
The getentropy() function may fail if:
[ENOSYS] The system does not provide the necessary
source of entropy.
RATIONALE
The getentropy() function is not a cancellation point.
Minor changes from the previous introduction of getentropy into libc:
- Return EINVAL, not EIO, on buflen > 256.
- Define GETENTROPY_MAX in limits.h.
The declaration of getentropy in unistd.h and definition of
GETENTROPY_MAX in limits.h are currently conditional on
_NETBSD_SOURCE. When the next revision of POSIX is finalized, we can
expose them also under _POSIX_C_SOURCE > 20yymmL as usual -- and this
can be done as a pullup without breaking existing compiled programs.

These tests run two threads for five seconds each to try to trigger
races in the event of broken memory barriers. They run only on
machines with at least two CPUs; on uniprocessor systems there's no

Driver module as illustrated here:
https://www.sparkfun.com/products/13911
A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.
The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

From their notes:
All new functionality should be explained by the updated manpage.
The manpage has been refactored a bit: A new section "Directives"
has been added and the information about default hostnames and
IPsec directives has been moved there, and the new file include
directive information is also there.
getconfigent has the most major changes. A newline is no longer
read immediately, but is called only by a "goto more" (inside an
if(false) block). This allows multiple definitions or directives
to exist on a single line for anything that doesn't terminate using
a newline. This means a key-values service definition can be followed
by another key-values service definition, a positional definition,
or an ipsec, hostname, or .include directive on the same line.
memset is no longer used explicitly to clear the servtab structure,
a function init_servtab() is used instead, which uses a C struct
initializer.
The servtab se_group field is its own allocation now, and not just
a pointer into the user:group string.
Refactored some stuff out of getconfigent to separate functions
for use by parse_v2.c. These functions in inetd.c are named with
the form parse_*()
parse_v2.c only has code for parsing a key-values service definition
into a provided servtab. It should not have anything that affects
global state other than line and line_number.
Some function prototypes, structures, and #defines have been moved
from inetd.c to inetd.h.
The function config_root replaces config as the function called on
a config file load/reload. The code removed from the end of
config(void) is now called in config_root, so it is not run on each
recursive config call.
setconfig(void) was removed and its code added into config_root
because that is the only place it is called, and redundant checks
for non-null globals were removed because they are always freed by
endconfig. The fseek code was also removed because the config files
are always closed by endconfig.
Rate limiting code was updated to add a per-service per-IP rate
limiting form. Some of that code was refactored out of other places
into functions with names in the form rl_*()
We have not added any of the license or version information to the
new files parse_v2.c, parse_v2.h, and inetd.h and we have not
updated the license or version info for inetd.c.
Security related:
The behavior when reading invalid IPsec strings has changed. Inetd
no longer exits, it quits reading the current config file instead.
Could this impact program security?
We have not checked for memory leaks. Solomon tried to use dmalloc
without success. getconfigent seemed to have a memory leak at each
"goto more". It seems like inetd has never free'd allocated strings
when throwing away erroneous service definitions during parsing
(i.e. when "goto more" is called when parsing fields). OpenBSD's
version calls freeconfig on "goto more"
(https://github.com/openbsd/src/blob/c5eae130d6c937080c3d30d124e8c8b86db7d625/usr.sbin/inetd/inetd.c#L1049)
but NetBSD only calls it when service definitions are no longer
needed. This has been fixed. freeconfig is called immediately before
any "goto more". There shouldn't be any time when a servtab is in
an invalid state where freeconfig would break.
