The resolver in libc creates a kqueue for watching a single file descriptor.
This can be done using poll() which should be lighter on the kernel and
reduce possible problems with rlimits (file descriptors, kqueues).

Redo r260506 by using the new TEST_METADATA functionality of bsd.test.mk
to mark the sh(1) and test(1) tests as not supporting root. This is to
get rid of hand-crafted Kyuafiles for these very simple cases.

Redo r260586 by using the new functionality in tap.test.mk to transparently
support perl-based test programs.
As a side-effect, we get rid of an explicit path to /usr/bin/perl by
replacing it with /usr/local/bin/perl (or as defined in tap.test.mk).
This also fixes the name of the legacy_test source file because this should
have always been legacy_test.pl and not legacy_test.sh. My mistake when
originally moving the code around without realizing that this was a perl
script.

Introduce a TAP_TESTS_PERL primitive to list test programs written in perl.
Only do this in tap.test.mk because I only expect perl-based test programs
with this interface.
This is very similar to TAP_TESTS_SH but the difference is that we record
in the Kyuafile that the test program requires a perl interpreter. This
in turn makes Kyua mark the test as skipped if the perl package is not yet
installed, instead of mysteriously failing to run the program.

Introduce a new, per-test-program TEST_METADATA.<program> variable that
contains a list of key/value paris describing metadata properties for
that test program. These properties are later written into the
auto-generated Kyuafile when using the KYUAFILE=auto functionality.
This is to avoid having to supply hand-crafted Kyuafiles when the needs
for metadata overrides are trivial.
While doing this, and because I am documenting TEST_METADATA, take the
chance to document the TEST_INTERFACE setting as well.

can be initiated in the context of a vcpu thread or from the bhyve(8) control

The first use of this functionality is to update the vlapic trigger-mode
register when the IOAPIC pin configuration is changed.
Prior to this change we would update the TMR in the virtual-APIC page at
the time of interrupt delivery. But this doesn't work with Posted Interrupts
because there is no way to program the EOI_exit_bitmap[] in the VMCS of
the target at the time of interrupt delivery.

standard core target by declaring coreops_suppress_target with
initializer. This is also happening for non-cross kgdb, by
virtue of having fbsd-threads.c in libgdb and having it do the
exact same thing. Since fbsd-threads.c is not included in in
libgdb when building a cross debugger, we ended up with more
than 1 core file targets (the standard gdb core file target and
kgdb's libkvm based core file target) and this behaves the same
as not having a core target at all.
one significant difference: for LIB32 builds both TARGET_ARCH
and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the
architecture of the host (e.g. amd64), while MACHINE_ARCH holds
the architecture were trying to build (e.g. i386). With both
set and different, r260022 changed the behaviour to interpret
the condition as building a cross-amd64 libkvm on i386, when
obviously we're trying to build an i386 version on amd64. When
COMPAT_32BIT is defined, we're building LIB32 and ignore the
value of TARGET_ARCH as we did before.
found in High Speed USB HUBs which translate from High Speed USB into
FULL or LOW speed USB. In some rare cases SPLIT transactions might get
lost, which might leave the TT in an unknown state. Whenever we detect
such an error try to issue either a clear TT buffer request, or if
that is not possible reset the whole TT.

The effect of this is that the test program is marked as skipped when perl
is missing, instead of marking it as broken due to an execution failure.

Do this by generating misc_helpers explicitly, without using the
ATF_TESTS_SH functionality.
While this script is technically an atf-sh test program, it is not intended
to be run as a test and therefore it mustn't end up in the Kyuafile. Using
ATF_TESTS_SH means that misc_helpers ended up registered in the Kyuafile
and then failed to run as a test.
The alternative would be to supply an explicit Kyuafile from this directory
that lists the known test files, but doing it the way described above will
be easier to maintain.

These files are required to get packages in ports to build against atf and
also to get a couple of currently-failing tests to pass.
I'm following the approach already used by the libusb pkg-config files

As a result, the kernel needs to process shorter pathnames if fts is not
changing directories (if fts follows symlinks (-L option to utilities), fts
cannot open "." or FTS_NOCHDIR was specified).
Side effect: If pathnames exceed PATH_MAX, [ENAMETOOLONG] is not hit at the
stat stage but later (opendir or application fts_accpath) or not at all.
vm_pageout_scan(). There were missing increments in two less common cases.
Don't conflate the count of stuck pages and the pageout deficit provided by
vm_page_alloc{,_contig}(). (A proposed fix to the OOM code depends on this.)
Handle held pages consistently in the inactive queue scan. In the more
common case, we did not move the page to the tail of the queue. Whereas, in
the less common case, we did. There's no particular reason to move the page
in the less common case, so remove it.
Perform the calculation of the page shortage for the active queue scan a
little earlier, before the active queue lock is acquired. The correctness
of this calculation doesn't depend on the active queue lock being held.
Eliminate a redundant variable, "pcount". Use the more descriptive
variable, "maxscan", in its place.
Apply a few nearby style fixes, e.g., eliminate stray whitespace and excess
parentheses.
