Tests an empty exect(2) executing
The function exect() executes a file with the program tracing facilities
enabled (see ptrace(2)).

This test will be attached to build afterwards.

can get missing entries!). Instead, as a temporary solution, we switch
to a simple linear scan of the hash tables for the longest-prefix-match
(lpm.c lpm.h) algorithm. In fact, with few unique prefixes in the set,
on modern hardware this simple algorithm is pretty fast anyway!

Appease it with initializing info to {0, 0}.

* Simultaneous playback and mixing of multiple streams
* Playback streams can be of different encoding, frequency, precision
and number of channels
* Simultaneous recording to different formats
* One audio device per process
* Sysctls to set the common format frequency, precision and channels
* Independent mixer controls for recording/playback per stream
* Utilizes little cpu time for multiple streams / good performance
* Compatible with existing programs that use OSS/NetBSD audio
* Changes to audioctl(1) to allow specifying process id for corresponding
audio device
In the MP-safe world, a rtentry stemming from a rtcache can be freed at any
points. So we need to protect rtentries somehow say by reference couting or
passive references. Regardless of the method, we need to call some release
function of a rtentry after using it.
The change adds a new function rtcache_unref to release a rtentry. At this
point, this function does nothing because for now we don't add a reference
to a rtentry when we get one from a rtcache. We will add something useful
in a further commit.
This change is a part of changes for MP-safe routing table. It is separated
to avoid one big change that makes difficult to debug by bisecting.
The framework provides a means to schedule if_start that will be executed
in softint later. It intends to be used to avoid calling if_start,
especially bpf_mtap, in hardware interrupt.
It adds a dedicated softint to a driver if the driver requests to use the
framework via if_deferred_start_init. The driver can schedule deferred
if_start by if_schedule_deferred_start.
Proposed and discussed on tech-kern and tech-net
Switch from:
child = atf_utils_fork();
to:
ATF_REQUIRE((child = fork()) != -1);
Prefer the latter as working as intended and not outputing to files with
danger to overwrite files' content after each fork in test-suite.
Discussed with Christos Zoulas.
