to the primary local IP address when doing a TCP connect(). The
tcp_connect() code was relying on in_pcbconnect (actually in_pcbladdr)
modifying the passed-in sockaddr, and I failed to notice this in
the recent change that added in_pcbconnect_setup(). As a result,
tcp_connect() was ending up using the unmodified sockaddr address
instead of the munged version.
There are two cases to handle: if in_pcbconnect_setup() succeeds,
then the PCB has already been updated with the correct destination
address as we pass it pointers to inp_faddr and inp_fport directly.
If in_pcbconnect_setup() fails due to an existing but dead connection,
then copy the destination address from the old connection.
This policy can be loaded dynamically, and assigns each process a
partition number, as well as permitting processes to operate outside
the partition. Processes contained in a partition can only "see"
processes inside the same partition, so it's a little like jail.
The partition of a user can be set using the label mechanisms in
login.conf. This sample policy is a good starting point for developers
wanting to learn about how to produce labeled policies, as it labels
only one kernel object, the process credential.

- Add detach support to the driver so that you can kldunload the module.
Note that currently rc_detach() fails to detach a unit if any of its
child devices are open, thus a kldunload will fail if any of the tty
devices are currently open.

In order to properly handle reset requests whether they originate in the
ATA layer (atacontrol reinit) or from the CAM layer (camcontrol reset)
ata_reinit does not cause the SIM to be deallocated anymore. The SIM
is now unconditionnally created for each ATAPI bus.
This change may cause existing bus ids to change on some setups.

system calls (almost identical to existing ones except that they permit
a pid to be specified for process label retrieval, and don't follow
symlinks). This generalizes the label API so that the framework is
now almost entirely policy-agnostic.

on all label parsing occuring in userland, and knowledge of the loaded
policies in the user libraries. This revision of the API pushes that
parsing into the kernel, avoiding the need for shared library support
of policies in userland, permitting statically linked binaries (such
as ls, ps, and ifconfig) to use MAC labels. In these API revisions,
high level parsing of the MAC label is done in the MAC Framework,
and interpretation of label elements is delegated to the MAC policy
modules. This permits modules to export zero or more label elements
to user space if desired, and support them in the manner they want
and with the semantics they want. This is believed to be the final
revision of this interface: from the perspective of user applications,
the API has actually not changed, although the ABI has.
