c4b21cbe4a Fix ipfw's initialization functions to get the correct order of evaluation
to allow vnet and non vnet operation. Move some functions from ip_fw_pfil.c
to ip_fw2.c and mode to mostly using the SYSINIT and VNET_SYSINIT handlers
instead of the modevent handler. Correct some spelling errors in comments
in the affected code. Note this bug fixes a crash in NON VIMAGE kernels when
ipfw is unloaded.

This patch is a minimal patch for 8.0
I have a much larger patch that actually fixes the underlying problems
that will be applied after 8.0

2b97862843 Bugfix: all requests for creating vnets via vimage -c were always
reported as failures, even if the actual library / system call
would succeed, because error message would be reported if the return
value from jail_setv() call was >= 0, and if not, then if that same
value was < 0, i.e. always.  The correct behavior is to abort (only)
if jail_setv() returns < 0.

eb5a1e8f38 This patch fixes two bugs in sglist(9) and improves robustness of the API via
better semantics if a request to append an address range to an existing list
fails.
- When cloning an sglist, properly set the length in the new sglist instead of
  leaving the new list empty.
- Properly compute the amount of data added to an sglist via
  _sglist_append_buf().  This allows sglist_consume_uio() to properly update
  uio_resid.
- When a request to append an address range to a scatter/gather list fails,
  restore the sglist to the state it had at the start of the function call
  instead of resetting it to an empty list.

ad3764ac1d vimage(8) is a legacy CLI interface for managing jails associated with
network stack instances, which is provided for compatibility with
older applications.  This change brings it back to life in a followup
to the initial conversion of vimage to use the new jail(4)
userland-kernel API:

- when creating vimages via "vimage -c", by default turn on a few
options expected by legacy applications, such as allow operations on
raw sockets, FS mounts etc, and allow jail-related parameters to be
optionally configured.

- introduce the "-m" modifier which allows for configuring jail
parameters of existing vimages / vnet-jails.

- make "vimage name command ..." actually work.

- when reassigning ifnets to vnets using "vimage -i", attempt to rename
the ifnet as "ethXXX" on arrival in the target vnet.  Several legacy
applications are known to depend heavily on such behavior.

- vimage -l lists only jails associated with vnets.  The output is
sorted using vimage / jail names as keys.

- vimage -l by default searches only the current level in the jail
hierarchy.  Recursive listing can be requested via -r switch.

- vimage -l by default prints only jail names on each line, making
such output suitable for pipelining to other commands.  More verbose
output can be obtained via -v switch, and even more jail specific
information will be displayed if -j switch is turned on.

- there's no need to build vimage as statically linked, so update the
Makefile accordingly.

- update the vimage.8 man page.

497e910cd3 fstat: fix fsid comparison when executed on systems with 64-bit long
This affects only fstat on zfs and devfs, only on 64-bit systems
and only when fsid is greater than 2^31 - 1.
When fstat examines a file via stat(2) it takes uint32_t st_dev
and assigns to (signed) (64-bit) long fsid, this results in
a positive value.
When fstat examines opened files it takes int32_t f_fsid.val[0]
and assigns to (signed) (64-bit) long fsid, this results in
a negative value.
So, while initially st_dev and f_fsid.val[0] have the same bit
values they get promoted to different 64-bit values because
of the signed-vs-unsigned difference.

A fix is to use "more natural" positive numbers by introducing
intermediate unsigned cast for f_fsid.val[0].

23d827ef05 Add support for backing up the old kernel when installing a new kernel
using freebsd-update.  This applies to using freebsd-update in "upgrade
mode" and normal freebsd-update on a security branch.

The backup kernel will be written to /boot/kernel.old, if the directory
does not exist, or the directory was created by freebsd-update in a
previous backup.  Otherwise freebsd-update will generate a new directory
name for use by the backup.  By default symbol files are not backed up
to save diskspace and avoid filling up the root partition.

This feature is fully configurable in the freebsd-update config file,
but defaults to enabled.

35d01728c6 Fix USB cache sync operations for platforms with non-coherent DMA.
- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
  so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
  cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
  the low level bus dma sync operation is implementation dependent and we
  cannot assume the required order of operations to be guaranteed.

- usb_pc_cpu_flush() is called before writing to a device, so
  BUS_DMASYNC_PREWRITE should be used.

faccac2d45 Correct a critical accounting error in pmap_demote_pde(). Specifically,
when pmap_demote_pde() allocates a page table page to implement a
user-space demotion, it must increment the pmap's resident page count.
Not doing so, can lead to an underflow during address space termination
that causes pmap_remove() to exit prematurely, before it has destroyed
all of the mappings within the specified range.  The ultimate effect or
symptom of this error is an assertion failure in vm_page_free_toq()
because the page being freed is still mapped.

This error is only possible when superpage promotion is enabled.  Thus,
it only affects FreeBSD  versions greater than 7.2.
