After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

When a user defines "jail_list" in rc.conf the jails are started in the
order defined. Currently the jails are not are stopped in reverse order
which may break dependencies between jails/services and prevent a clean
shutdown. The new parameter "jail_reverse_stop" will shutdown jails in
"jail_list" in reverse order when set to "YES".
Please note that this does not affect manual invocation of the jail rc
script. If a user runs the command
# service jail stop jail1 jail2 jail3
the jails will be stopped in exactly the order specified regardless of
jail_reverse_stop being defined in rc.conf.

With this change, it's possible to redefine rc_conf_files (e.g.,

diff(1) output between two files in "new_only"-mode. Otherwise,
with the default of using unified format a remnant of the header
in the output is the result. This is especially irritating when
the two files differ but the second one is empty, amounting to the
vestige of the header being the only readout.

- tests/sys/geom/class/Makefile.inc is not present; it was

- The testcases officially require root via kyua

Fix a bug in rpcbind for multihomed hosts. If the server had interfaces on
two separate subnets, and a client on the first subnet contacted rpcbind at
the address on the second subnet, rpcbind would advertise addresses on the
first subnet. This is a bug, because it should prefer to advertise the
address where it was contacted. The requested service might be firewalled
off from the address on the first subnet, for example.
usr.sbin/rpcbind/check_bound.c
If the address on which a request was received is known, pass that
to addrmerge as the clnt_uaddr parameter. That is what addrmerge's
comment indicates the parameter is supposed to mean. The previous
behavior is that clnt_uaddr would contain the address from which the
client sent the request.
usr.sbin/rpcbind/util.c
Modify addrmerge to prefer to use an IP that is equal to clnt_uaddr,
if one is found. Refactor the relevant portion of the function for
clarity, and to reduce the number of ifdefs.

USB NICs.
USB network hardware may not be enumerated and available when the rc.d
networking scripts run. Eventually the USB attachment completes and devd
events cause the network initialization to happen, but by then other rc.d
scripts have already failed, because services which depend on NETWORKING
(such as mountcritremote) may end up running before the network is actually
ready.
There is an existing netwait script, but because it is dependent on
NETWORKING it runs too late to prevent failure of some other rc
scripts. This change flips the order so that NETWORKING depends on netwait,
and netwait now depends on devd and routing (the former is needed to make
interfaces appear, and the latter is needed to run the ping tests in
netwait).
The netwait script used to be oriented primarily towards "as soon as any
host is reachable the network is fully functional", so you gave it a list of
IPs to try and you could optionally name an interface and it would wait for
carrier on that interface. That functionality still works the same, but now
you can provide a list of interfaces to wait for and it waits until each one
of them is available. The ping logic still completes as soon as the first IP
on the list responds.
These changes were submitted by Brenden Molloy <brendan+freebsd@bbqsrc.net>
in PR 205186, and lightly modified by me to allow a list of interfaces
instead of just one.

Currently rc scripts implementing their own start_cmd do not enjoy the
benefits of rc.subr's own check for rc_pid.
This leads to around a third of ports with such a start_cmd not to check for
the process at all and two thirds of ports to re-implement this check
(sometimes wrongly).
This patch moves the check for rc_pid to before ${rc_arg}_cmd is executed.
