wildcard specifications. Earlier the only wildcard syntax
was "-j 0" for "any jail". There were at least
two shortcomings in it: First, jail ID 0 was abused; it
meant "no jail" in other utils, e.g., ps(1). Second, it
was impossible to match processed not in jail, which could
be useful to rc.d developers. Therefore a new syntax is
introduced: "-j any" means any jail while "-j none" means
out of jail. The old syntax is preserved for compatibility,
but now it's deprecated because it's limited and confusing.
Update the respective regression tests. While I'm here,
make the tests more complex but sensitive: Start several
processes, some in jail and some out of jail, so we can
detect that only the right processes are killed by pkill
or matched by pgrep.

relating to O_RDWR file descriptors, which while not defined in POSIX,
are in fact used:
(1) Revise assumption that we have two file descriptors when testing I/O
operations on a fifo. Provide cleanup routines that handle either
two or three file descriptors (including a kqueue descriptor).
(2) Add an openfifo_rw() routine to supplement openfifo().
(3) kqueue_setup() now configures an existing kqueue to monitor a new
file descriptor, rather than allocating a new kqueue to monitor two
existing file descriptors.
(4) Wrap all direct poll/select/kqueue/FIONREAD interactions in a single
function, assert_status(), which takes a file descriptor, kqueue
descriptor, assertion of read/writable/exception states, and
test description, then tests the assertion. This reduces the bulk
of calls in many of the tests, making them shorter, more readable,
and easier to determine correct.
(5) Add a new test_events_rdwr() function, which performs a basic create/
write/read event test on a O_RDWR fifo file descriptor. This is
currently failed by our fifo code in HEAD due to a bug in FIONREAD
handling. Fix to be merged shortly.
Add test_kqueue(), which registers and unregisters various kqueue filter
types on a fifo in order to make sure that EVFILT_READ, EVFILT_WRITE can
be registered, and that EVFILT_NETDEV can't be registered. For now, we
don't test that EVFILT_VNODE can be registered on fifos, as that has been
broken at some point.
- Teach fifo_io about kqueue monitoring of fifo file descriptor status,
and add test cases for kqueue to match existing case for poll and
select. Add a new cleanup routine, cleanfifokq(), for use in tests that
use kqueues. kqueue_setup() sets up kqueue sessions, and kqueue_status()
returns file descriptor status.
- Correct a bug in select handling relating to the nfds argument, which
was incorrect so resulted in select occuring on the wrong file descriptor,
and possible false positive/negative results.
- Clarify error reporting in one byte write+read tests to distinguish
errors in the after case from the before case.
