kqueue(2) already supports EVFILT_PROC. Add an EVFILT_PROCDESC that
behaves the same, but operates on a procdesc(4) instead. Only implement
NOTE_EXIT for now. The nice thing about NOTE_EXIT is that it also
returns the exit status of the process, meaning that we can now obtain
this value, even if pdwait4(2) is still unimplemented.
Notes:
- Simply reuse EVFILT_NETDEV for EVFILT_PROCDESC. As both of these will
be used on totally different descriptor types, this should not clash.
- Let procdesc_kqops_event() reuse the same structure as filt_proc().
The only difference is that procdesc_kqops_event() should also be able
to deal with the case where the process was already terminated after
registration. Simply test this when hint == 0.
- Fix some style(9) issues in filt_proc() to keep it consistent with the
newly added procdesc_kqops_event().
- Save the exit status of the process in pd->pd_xstat, as we cannot pick
up the proctree_lock from within procdesc_kqops_event().

are unaware of RFC 3542 can construct control messages.
The kernel disallows mixing RFC 2292 behaviour with RFC 3542 behaviour.
Only sockets that have specifically been marked as using the RFC 2292
API can use RFC 2292 specific options. This is all good and well, but
libc itself seems inconsistent with this.
The root cause of this inconsistency seems to relate to the definitions
of IPV6_HOPOPTS and IPV6_DSTOPTS. They are defined in RFC 2292 and re-used
in RFC 3542, yet have distinct values in the kernel. It's for this reason
that the kernel also has definitions for IPV6_2292HOPOPTS and
IPV6_2292DSTOPTS. Not so in libc.
For example: some program calls inet6_option_init() (defined by RFC 2292)
with the RFC 2292 defined IPV6_HOPOPTS and IPV6_DSTOPTS. Before RFC 3542,
this was translated to values of 22 and 23 (resp.) The libc implementation
correctly checks that only options IPV6_HOPOPTS and IPV6_DSTOPTS are given
(as per RFC 2292) but since these defines have taken on the values defined
by RFC 3542 (values 49 and 50 resp,) rejects the correct option values
(22 and 23) passed said program and returns -1.
The precisie fix is to have inet6_option_init() and friends only accept the
RFC 2292 defined IPV6_HOPOPTS & IPV6_DSTOPTS, but that breaks other code
(like mld6query(8)), which seem to not be aware of RFC 3542 and how it
hi-jacked the option names. So the best fix is to accept the options from
both.

The pdfork(2) man page states:
"pdfork() returns a PID, 0 or -1, as fork(2) does."
As it returns a PID, the return type should obviously be pid_t. As int

from any context i.e., it is not required to be called from a vcpu thread. The
ioctl simply sets a state variable 'vm->suspend' to '1' and returns.
The vcpus inspect 'vm->suspend' in the run loop and if it is set to '1' the
vcpu breaks out of the loop with a reason of 'VM_EXITCODE_SUSPENDED'. The
suspend handler waits until all 'vm->active_cpus' have transitioned to
'vm->suspended_cpus' before returning to userspace.

all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with

This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.
armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
* WITH_ARM_EABI
* WITHOUT_GCC
* WITHOUT_GNUCXX
In addition, without an external toolchain, the following need to be left
as their default:
* WITH_CLANG
* WITH_CLANG_IS_CC
As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.

my tests, it is faster ~20%, even on an old IXP425 533MHz it is ~45%
faster... This is partly due to loop unrolling, so the code size does
significantly increase... I do plan on committing a version that
rolls up the loops again for smaller code size for embedded systems
where size is more important than absolute performance (it'll save ~6k
code)...

Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk. Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.
The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.
Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner. Coming soon.
IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.
Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.
The previous code failed to return an error condition when the whole input
was invalid due to improper handling of the sscanf return value. Actually,
this failure was properly being caught by a test in
tools/regression/lib/libc/net/test-ether.t but was not noticed because
these tests are never run. (On my way to fixing that ;-)
The fix applied here resembles the implementation of ether_line in NetBSD
modulo the setting of an errno value (which is not documented as an
expectation in the manpage anyway).
