ae8e7ec2a3 - Add constants for the different memory types in the SMAP table.
- Use the SMAP types and constants from <machine/pc/bios.h> in the boot
  code rather than duplicating it.

54102acdd3 Garbage collect mac_mbuf_create_multicast_encap TrustedBSD MAC Framework
entry point, which is no longer required now that we don't support
old-style multicast tunnels.  This removes the last mbuf object class
entry point that isn't init/copy/destroy.

369fd04f48 Continue to move from generic network entry points in the TrustedBSD MAC
Framework by moving from mac_mbuf_create_netlayer() to more specific
entry points for specific network services:

- mac_netinet_firewall_reply() to be used when replying to in-bound TCP
  segments in pf and ipfw (etc).

- Rename mac_netinet_icmp_reply() to mac_netinet_icmp_replyinplace() and
  add mac_netinet_icmp_reply(), reflecting that in some cases we overwrite
  a label in place, but in others we apply the label to a new mbuf.

2bca3d4001 Move towards more explicit support for various network protocol stacks
in the TrustedBSD MAC Framework:

- Add mac_atalk.c and add explicit entry point mac_netatalk_aarp_send()
  for AARP packet labeling, rather than using a generic link layer
  entry point.

- Add mac_inet6.c and add explicit entry point mac_netinet6_nd6_send()
  for ND6 packet labeling, rather than using a generic link layer entry
  point.

- Add expliict entry point mac_netinet_arp_send() for ARP packet
  labeling, and mac_netinet_igmp_send() for IGMP packet labeling,
  rather than using a generic link layer entry point.

- Remove previous genering link layer entry point,
  mac_mbuf_create_linklayer() as it is no longer used.

- Add implementations of new entry points to various policies, largely
  by replicating the existing link layer entry point for them; remove
  old link layer entry point implementation.

- Make MAC_IFNET_LOCK(), MAC_IFNET_UNLOCK(), and mac_ifnet_mtx global
  to the MAC Framework rather than static to mac_net.c as it is now
  needed outside of mac_net.c.

3bce611192 Actually the keyword tells network.subr to launch wpa_supplicant on the
selected interface. wpa_supplicant does not only handle WPA
authentication but also EAP/LEAP as well as WEP encryption or no
encryption at all. The patch clarifies this.

7fc8683d7c When skipping input data, don't overflow a 32-bit size_t.
This can only happen on 32-bit systems when you're reading
an uncompressed archive and the skip request is an exact
multiple of 4G (e.g., skipping a tar entry with an 8G body).

The symptom is that the read_ahead() ends up returning zero
bytes, and the extraction stops with a premature end-of-file.

Using '1' here is more correct anyway, as it allows read_ahead()
to function opportunistically and minimize copying.

3ee3b45ab8 Change the roundrobin implementation in the 4BSD scheduler to trigger a
userland preemption directly from hardclock() via sched_clock() when a
thread uses up a full quantum instead of using a periodic timeout to cause
a userland preemption every so often.  This fixes a potential deadlock
when IPI_PREEMPTION isn't enabled where softclock blocks on a lock held
by a thread pinned or bound to another CPU.  The current thread on that
CPU will never be preempted while softclock is blocked.

Note that ULE already drives its round-robin userland preemption from
sched_clock() as well and always enables IPI_PREEMPT.

2913d80333 Allow the shell used by make(1) to be changed early via the

31933d8615 if_loop doesn't need to keep the list of lo(4) interfaces. Today
a private softc list is needed neither for tracking clones in general
nor for destroying all clones before the module unload -- if_clone
takes care of all that.  (Note that some other interface drivers do
need a softc list to be able to scan it for their private purposes.)

bd7f6192a0 Add some essential tools to rescue(8) in order to make it
a versatile emergency tool:

o sed(1) as a multi-purpose text filter -- can do grep's job and much more.
o head(1), tail(1), and tee(1) as idiomatic text filters.
o mt(1) to control tape drives (PR misc/98383).
o chown(8) aka chgrp(8) to complement the ch* subset.
o pkill(1) aka pgrep(1) to control running processes easily and thus to be
  able to recover from a serious problem or a fatal typo in an otherwise live
  system w/o a reboot.  (It also deserves adding to rescue(8) for its having
  triggered a latent bug in crunchgen(1), but we had better add a regression
  test for that. :-)

The resulting change in rescue(8) size has the following order of magnitude
on i386: 3787656 - 3727872 = 59784, i.e. just a tad.

aa4d1c093f Add the following mount options to the nfs_opts array:
noatime, noexec, suiddir, nosuid, nosymfollow, union,
noclusterr, noclusterw, multilabel, acls, force, update,
async.  These options correspond to MOPT_STDOPTS, MOPT_FORCE, MOPT_UPDATE,
and MOPT_ASYNC.

Currently, mount_nfs converts these "-o" options from strings
to MNT_ flags via getmntopts(),
and passes the flags from userspace to the kernel.
This change will allow us in future to pass these mount options
as strings directly to the kernel via nmount() when doing NFS mounts.

59761712e0 Set the program name if the crunched program is selected through
argv[1] to mimic crt0 behaviour.  Do the job by a direct assignment
to __progname in order to stay compatible with NetBSD, whose
setprogname() is a deliberate no-op.

The reason for this change is that some programs (usually those
imported from NetBSD) use getprogname() to distinguish between their
aliases.  (See pkill aka pgrep for example.)

This change can be useful, and applicable, to NetBSD, too.

0b0826633e In nmount(), if MNT_ROOT is in the mount flags, filter it
out instead of returning an error.
(1)  This makes the behavior consistent with mount(2).
(2)  This makes update mounts on the root file system work properly.
(3)  The explicit checks for MNT_ROOTFS in src/sbin/fsck_ffs/main.c
     and src/usr.sbin/mountd/mountd.c which were put in to
     eliminate errors during update mounts on the root file system
     can be removed.

The only place were MNT_ROOTFS can be validly set
is inside the kernel, i.e. with vfs_mountroot_try().
