This is a workaround for WITH_LDNS_UTILS forcing BIND_UTILS off. It can
be reverted when we no longer have these conflicting options, or made more
general if we grow more cases like this.
This small utility performs a sequence of atomic operations with random
parameters on an atomic variable. For every type, we also create 16
variables, to ensure that we test the correctness at different
alignments.
debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.
The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.
Thanks to everyone who contributed changes, review, and testing during
development.
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).

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

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+".
