05b262e264 This patch adds a host route to an interface address (that is assigned
to a non loopback/ppp link type) through the loopback interface. Prior
to the new L2/L3 rewrite, this host route was explicitly created when
processing the IPv6 address assignment. This loopback host route is
deleted when that IPv6 address is removed from the interface.

USB CORE: busdma improvement

      For single segment allocations the boundary field
      of the BUSDMA tag should be zero. Currently all
      single segment allocations are less than or equal
      to 4096 bytes, so the limit does not kick in. If
      any single segment USB allocations would be greater
      than 4K, then it would be a problem.

529ab57b9a When VM_MAP_WIRE_HOLESOK is not specified and vm_map_wire(9) encounters
non-readable and non-executable map entry, the entry is skipped from
wiring and loop is aborted. But, since MAP_ENTRY_WIRE_SKIPPED was not
set for the map entry, its wired_count is later erronously decremented.
vm_map_delete(9) for such map entry stuck in "vmmaps".

Properly set MAP_ENTRY_WIRE_SKIPPED when aborting the loop.

back to the 8 branch:

tcp_var.h
- struct sackhint
- struct tcpcb
- struct tcpstat

The patch breaks the ABI. Bump __FreeBSD_version to 800102 accordingly. User
space tools that rely on the size of any of these structs (e.g. sockstat) need

31d22003dd Rename option USBVERBOSE to USB_VERBOSE for 2 reasons:
1.  USB_VERBOSE is more consistent with USB_DEBUG,
2.  sys/dev/usb/usb_device.c uses option USB_VERBOSE and
    not USBVERBOSE.

POLA with the USBVERBOSE option as it's found in 7-STABLE
has been considered but found insignificant in the face
of the USB stack overhaul.

b54b764c72 Revert rev 192323 (nfs_common.c only):
The D-cache flushing added here was to deal with I-cache
incoherency observed on ia64. However, the problem was
in the implementation of pmap_enter_object() for ia64:
it was missing I-cache coherency logic for prefaulted
pages. After this got added in rev 195625, testing showed
that no D-cache flushing was required.

The SIGILL that was observed on Book-E (see commit log
for rev 192323) ended up not being related to I-cache
incoherency, but was found to be caused by bad memory.
This discovery further undermined the need for D-cache
flushing in the NFS I/O code, triggering the reversal.

dd8a461e83 In nvpair_native_embedded_array(), meaningless pointers are zeroed.
The programmer was aware that alignment was not guaranteed in the
packed structure and used bzero() to NULL out the pointers.
However, on ia64, the compiler is quite agressive in finding ILP
and calls to bzero() are often replaced by simple assignments (i.e.
stores). Especially when the width or size in question corresponds
with a store instruction (i.e. st1, st2, st4 or st8).

The problem here is not a compiler bug. The address of the memory
to zero-out was given by '&packed->nvl_priv' and given the type of
the 'packed' pointer the compiler could assume proper alignment for
the replacement of bzero() with an 8-byte wide store to be valid.
The problem is with the programmer. The programmer knew that the
address did not have the alignment guarantees needed for a regular
assignment, but failed to inform the compiler of that fact. In
fact, the programmer told the compiler the opposite: alignment is
guaranteed.

The fix is to avoid using a pointer of type "nvlist_t *" and
instead use a "char *" pointer as the basis for calculating the
address. This tells the compiler that only 1-byte alignment can
be assumed and the compiler will either keep the bzero() call
or instead replace it with a sequence of byte-wise stores. Both
are valid.

7d845dde8d Remove build timestamps from the following files:
/boot/kernel/hptrr.ko
/etc/mail/*.cf
/lib/libcrypto.so.5
/usr/bin/ntpq
/usr/sbin/amd
/usr/sbin/iasl
/usr/sbin/ntpd
/usr/sbin/ntpdate
/usr/sbin/ntpdc

There does not appear to be any purpose to having these timestamps, and
they have the irritating consequence that the aforementioned files will
be different every time they are rebuilt.

After this commit, the only remaining build timestamps are in the kernel,
the boot loaders, /usr/include/osreldate.h (the year in the copyright
notice), and lib*.a (the timestamps on all of the included .o files).

1ed01448fb On exec(2), when loading the ELF image, pmap_enter_object() is
called to prefault pages. This is an obvious place for making
sure the I-cache is coherent. It was missing though. As such,
execution over NFS and ZFS file systems was failing. NFS was
fixed the wrong way (by flushing the D-cache as part of the
NFS code) in a previous commit. ZFS problems were encountered
after that and indicated that something else was wrong...

59aa14a91d Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

d77e2734a1 When amd64 CPU cannot load segment descriptor during trap return to
usermode, it generates GPF, that is mirrored to user mode as SIGSEGV.
The offending register in mcontext should contain the value loading of
which generated the GPF, and it is so on i386. On amd64, we currently
report segment descriptor in tf_err, while segment register contains the
corrected value loaded by trap handler.

Fix the issue by behaving like i386, reloading segment register in trap
frame after signal frame is pushed onto user stack.

52c9ce25d8 Separate the parallel scsi knowledge out of the core of the XPT, and
modularize it so that new transports can be created.

Add a transport for SATA

Add a periph+protocol layer for ATA

Add a driver for AHCI-compliant hardware.

Add a maxio field to CAM so that drivers can advertise their max
I/O capability.  Modify various drivers so that they are insulated
from the value of MAXPHYS.

The new ATA/SATA code supports AHCI-compliant hardware, and will override
the classic ATA driver if it is loaded as a module at boot time or compiled
into the kernel.  The stack now support NCQ (tagged queueing) for increased
performance on modern SATA drives.  It also supports port multipliers.

ATA drives are accessed via 'ada' device nodes.  ATAPI drives are
accessed via 'cd' device nodes.  They can all be enumerated and manipulated
via camcontrol, just like SCSI drives.  SCSI commands are not translated to
their ATA equivalents; ATA native commands are used throughout the entire
stack, including camcontrol.  See the camcontrol manpage for further
details.  Testing this code may require that you update your fstab, and
possibly modify your BIOS to enable AHCI functionality, if available.

This code is very experimental at the moment.  The userland ABI/API has
changed, so applications will need to be recompiled.  It may change
further in the near future.  The 'ada' device name may also change as
more infrastructure is completed in this project.  The goal is to
eventually put all CAM busses and devices until newbus, allowing for
interesting topology and management options.

Few functional changes will be seen with existing SCSI/SAS/FC drivers,
though the userland ABI has still changed.  In the future, transports
specific modules for SAS and FC may appear in order to better support
the topologies and capabilities of these technologies.

The modularization of CAM and the addition of the ATA/SATA modules is
meant to break CAM out of the mold of being specific to SCSI, letting it
grow to be a framework for arbitrary transports and protocols.  It also
allows drivers to be written to support discrete hardware without
jeopardizing the stability of non-related hardware.  While only an AHCI
driver is provided now, a Silicon Image driver is also in the works.
Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware
is possible and encouraged.  Help with new transports is also encouraged.

9ca27b565b Since the nfscl_getclose() function both decremented open counts and,
optionally, created a separate list of NFSv4 opens to be closed, it
was possible for the associated OpenOwner to be free'd before the Open
was closed. The problem was that the Open was taken off the OpenOwner
list before the Close RPC was done and OpenOwners can be free'd once the
list is empty. This patch separates out the case of doing the Close RPC
into a separate function called nfscl_doclose() and simplifies nfsrpc_doclose()
so that it closes a single open instead of a list of them. This avoids
removing the Open from the OpenOwner list before doing the Close RPC.
