existing devices (e.g.: tunX). This may need a little more thought.
Create a /dev/netX alias for devices. net0 is reserved.
Allow wiring of net aliases in /boot/device.hints of the form:
hint.net.1.dev="lo0"
hint.net.12.ether="00:a0:c9:c9:9d:63"
for initializing the parts. Since I don't have any of these parts in
any of my working laptops, I'm committing this to allow people to test
it. Will MFC when I receive reports of it working.
non-backward compatible changes in the format of packing list and handle
them gracefully;
- fix a longstanding issue with symlinks handling. Instead of recording
checksum for the file symlink points to, record checksum for the value
returned by readlink(2). For backward compatibility increase packing list
format minor version number and provide a fallback to a previous behaviour,
if package in question was created with older version of pkg_* tools;

files.

a single kern.security.seeotheruids_permitted, describes as:
"Unprivileged processes may see subjects/objects with different real uid"
NOTE: kern.ps_showallprocs exists in -STABLE, and therefore there is
an API change. kern.ipc.showallsockets does not.
- Check kern.security.seeotheruids_permitted in cr_cansee().
- Replace visibility calls to socheckuid() with cr_cansee() (retain
the change to socheckuid() in ipfw, where it is used for rule-matching).
- Remove prison_unpcb() and make use of cr_cansee() against the UNIX
domain socket credential instead of comparing root vnodes for the
UDS and the process. This allows multiple jails to share the same
chroot() and not see each others UNIX domain sockets.
- Remove unused socheckproc().
Now that cr_cansee() is used universally for socket visibility, a variety
of policies are more consistently enforced, including uid-based
restrictions and jail-based restrictions. This also better-supports
the introduction of additional MAC models.

code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

global kern_unprivileged_procdebug_permitted policy might disallow
this.
o Move the kern_unprivileged_procdebug_permitted check above the
