This is required by POSIX, at least for pids that are not known child
processes.
Other problems with job specifications still cause wait to abort with
exit status 2.

This is only part of the PR; the behaviour for unknown/invalid pids/jobs
remains unchanged (aborts the builtin with status 2).

+ pkt-gen -f rx now remains active even when traffic stops
Previous behaviour (exit after 1 second of silence) can be
restored with the -W option
+ the -X option does a hexdump of the content of a packet (both tx and rx).
This can be useful to check what goes in and out.
+ the -I option instructs the sender to use indirect buffers
(not really useful other than to test the kernel module in the
VALE switch)
I initially thought wchar_t was locale independent, but this seems to be
only the case on Linux. This means that we cannot depend on the *wc*()
routines to implement *c16*() and *c32*(). Instead, use the Citrus
libiconv that is part of libc.
I'll see if there is anything I can do to make the existing functions
somewhat useful in case the system is built without libiconv in the
nearby future. If not, I'll simply remove the broken implementations.

long double versions don't pass yet. (They are rather nit-picky cases,
so there's ongoing discussion with Bruce about whether it is worth the
performance cost.)
because different tests have different ideas about what it means to be
"close enough" to the right answer, depending on the properties of the
function being tested. In the process, I fixed some warnings and
added a few more 'volatile' hacks, which are sufficient to make all
the tests pass at -O2 with clang.
This reverts commit r247274.
As maintainer of sh, I disapprove of this feature addition.
It is too specific and can be done without easily using find(1) or stat(1).
I will add some hints to the test(1) man page shortly.
In general, FreeBSD sh is not the place to invent new shell language
features. This is how it has been maintained and adding features randomly
does not work with that.
The new syntax (e.g. [ FILE1 -ntca FILE2 ]) looks cryptic to me.
In most shells (including our sh), break outside a loop does nothing with
status 0, or at least does not abort. Therefore, scripts sometimes (buggily)
depend on this.
- the VALE switch now support up to 254 destinations per switch,
unicast or broadcast (multicast goes to all ports).
- we can attach hw interfaces and the host stack to a VALE switch,
which means we will be able to use it more or less as a native bridge
(minor tweaks still necessary).
A 'vale-ctl' program is supplied in tools/tools/netmap
to attach/detach ports the switch, and list current configuration.
- the lookup function in the VALE switch can be reassigned to
something else, similar to the pf hooks. This will enable
attaching the firewall, or other processing functions (e.g. in-kernel
openvswitch) directly on the netmap port.
The internal API used by device drivers does not change.
Userspace applications should be recompiled because we
bump NETMAP_API as we now use some fields in the struct nmreq
that were previously ignored -- otherwise, data structures
are the same.
Manpages will be committed separately.

Small values are used in the new tests such that cosine and sine are well
defined.

are workarounds for various symptoms of the problem described in clang
bugs 3929, 8100, 8241, 10409, and 12958.
The regression tests did their job: they failed, someone brought it
up on the mailing lists, and then the issue got ignored for 6 months.
Oops. There may still be some regressions for functions we don't have
test coverage for yet.
The <uchar.h> header, part of C11, adds a small number of utility
functions for 16/32-bit "universal" characters, which may or may not be
UTF-16/32. As our wchar_t is already ISO 10646, simply add light-weight
wrappers around wcrtomb() and mbrtowc().
While there, also add (non-yet-standard) _l functions, similar to the
ones we already have for the other locale-dependent functions.

If 'e' is used, the kernel must support the recently added pipe2() system
call.
The use of pipe2() with O_CLOEXEC also fixes race conditions between
concurrent popen() calls from different threads, even if the close-on-exec
flag on the fd of the returned FILE is later cleared (because popen() closes
all file descriptors from earlier popen() calls in the child process).
Therefore, this approach should be used in all cases when pipe2() can be
assumed present.
The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".

To speed build times, if XCC is an absolute path or
WITHOUT_CROSS_COMPILER is defined then no cross compiler will be built

This test case sometimes fails because of an EINTR-related race condition.
Fixing this race condition likely requires an extra system call per byte,
which would make the read builtin even slower than it already is, or very
complicated trickery. Therefore, remove the test case for now.
* If read -t times out, return status as if interrupted by SIGALRM
(formerly 1).
* If a trapped signal interrupts read, return status 128+sig (formerly 1).
* If [EINTR] occurs but there is no trap, retry the read (for example
because of a SIGWINCH in interactive mode).
* If a read error occurs, write an error message and return status 2.
As before, a variable assignment error returns 2 and discards the remaining
data read.
Generate images sparsely. This saves space and time, especially when

Add a 'true' statement to last_orders to prevent some version of sh from
