f4e24c4e7a Fix compile warnings building on amd64. This is modified slightly
from Jaakko's original patch: I have misgivings about the portability
of the 'z' printf modifier so opted to cast the arguments to (int)
instead.

2ff47c5f18 Remove unnecessary locking around vn_fullpath(). The vnode lock for the
vnode in question does not need to be held.  All the data structures used
during the name lookup are protected by the global name cache lock.
Instead, the caller merely needs to ensure a reference is held on the
vnode (such as vhold()) to keep it from being freed.

In the case of procfs' <pid>/file entry, grab the process lock while we
gain a new reference (via vhold()) on p_textvp to fully close races with
execve(2).

For the kern.proc.vmmap sysctl handler, use a shared vnode lock around
the call to VOP_GETATTR() rather than an exclusive lock.

size changes.  Change the number of lines before each header to the
current lines of the terminal when the terminal is resized, so that

eabe30fc9c Bring in USB4BSD, Hans Petter Selasky rework of the USB stack
that includes significant features and SMP safety.

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:

1) A brief feature list:

  - A new and mutex enabled USB API.

  - Many USB drivers are now running Giant free.

  - Linux USB kernel compatibility layer.

  - New UGEN backend and libusb library, finally solves the "driver
    unloading" problem. The new BSD licensed libusb20 library is fully
    compatible with libusb-0.1.12 from sourceforge.

  - New "usbconfig" utility, for easy configuration of USB.

  - Full support for Split transactions, which means you can use your
    full speed USB audio device on a high speed USB HUB.

  - Full support for HS ISOC transactions, which makes writing drivers
    for various HS webcams possible, for example.

  - Full support for USB on embedded platforms, mostly cache flushing
    and buffer invalidating stuff.

  - Safer parsing of USB descriptors.

  - Autodetect of annoying USB install disks.

  - Support for USB device side mode, also called USB gadget mode,
    using the same API like the USB host side. In other words the new
    USB stack is symmetric with regard to host and device side.

  - Support for USB transfers like I/O vectors, means more throughput
    and less interrupts.

  - ... see the FreeBSD quarterly status reports under "USB project"

2) To enable the driver in the default kernel build:

2.a) Remove all existing USB device options from your kernel config
file.

2.b) Add the following USB device options to your kernel configuration
file:

# USB core support
device          usb2_core

# USB controller support
device		usb2_controller
device		usb2_controller_ehci
device		usb2_controller_ohci
device		usb2_controller_uhci

# USB mass storage support
device		usb2_storage
device		usb2_storage_mass

# USB ethernet support, requires miibus
device		usb2_ethernet
device		usb2_ethernet_aue
device		usb2_ethernet_axe
device		usb2_ethernet_cdce
device		usb2_ethernet_cue
device		usb2_ethernet_kue
device		usb2_ethernet_rue
device		usb2_ethernet_dav

# USB wireless LAN support
device		usb2_wlan
device		usb2_wlan_rum
device		usb2_wlan_ral
device		usb2_wlan_zyd

# USB serial device support
device		usb2_serial
device		usb2_serial_ark
device		usb2_serial_bsa
device		usb2_serial_bser
device		usb2_serial_chcom
device		usb2_serial_cycom
device		usb2_serial_foma
device		usb2_serial_ftdi
device		usb2_serial_gensa
device		usb2_serial_ipaq
device		usb2_serial_lpt
device		usb2_serial_mct
device		usb2_serial_modem
device		usb2_serial_moscom
device		usb2_serial_plcom
device		usb2_serial_visor
device		usb2_serial_vscom

# USB bluetooth support
device		usb2_bluetooth
device		usb2_bluetooth_ng

# USB input device support
device		usb2_input
device		usb2_input_hid
device		usb2_input_kbd
device		usb2_input_ms

# USB sound and MIDI device support
device		usb2_sound

2) To enable the driver at runtime:

2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.

2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.

30f60d8c31 Remove the mnt_holdcnt and mnt_holdcntwaiters because they are useless.
Really, the concept of holdcnt in the struct mount is rappresented by
the mnt_ref (which prevents the type-stable structure from being
"recycled) handled through vfs_ref() and vfs_rel().
On this optic, switch the holdcnt acquisition into an emulated vfs_ref()
(and subsequent release into vfs_rel()).

a9148abd9d Implement support for RPCSEC_GSS authentication to both the NFS client
and server. This replaces the RPC implementation of the NFS client and
server with the newer RPC implementation originally developed
(actually ported from the userland sunrpc code) to support the NFS
Lock Manager.  I have tested this code extensively and I believe it is
stable and that performance is at least equal to the legacy RPC
implementation.

The NFS code currently contains support for both the new RPC
implementation and the older legacy implementation inherited from the
original NFS codebase. The default is to use the new implementation -
add the NFS_LEGACYRPC option to fall back to the old code. When I
merge this support back to RELENG_7, I will probably change this so
that users have to 'opt in' to get the new code.

To use RPCSEC_GSS on either client or server, you must build a kernel
which includes the KGSSAPI option and the crypto device. On the
userland side, you must build at least a new libc, mountd, mount_nfs
and gssd. You must install new versions of /etc/rc.d/gssd and
/etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf.

As long as gssd is running, you should be able to mount an NFS
filesystem from a server that requires RPCSEC_GSS authentication. The
mount itself can happen without any kerberos credentials but all
access to the filesystem will be denied unless the accessing user has
a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There
is currently no support for situations where the ticket file is in a
different place, such as when the user logged in via SSH and has
delegated credentials from that login. This restriction is also
present in Solaris and Linux. In theory, we could improve this in
future, possibly using Brooks Davis' implementation of variant
symlinks.

Supporting RPCSEC_GSS on a server is nearly as simple. You must create
service creds for the server in the form 'nfs/<fqdn>@<REALM>' and
install them in /etc/krb5.keytab. The standard heimdal utility ktutil
makes this fairly easy. After the service creds have been created, you
can add a '-sec=krb5' option to /etc/exports and restart both mountd
and nfsd.

The only other difference an administrator should notice is that nfsd
doesn't fork to create service threads any more. In normal operation,
there will be two nfsd processes, one in userland waiting for TCP
connections and one in the kernel handling requests. The latter
process will create as many kthreads as required - these should be
visible via 'top -H'. The code has some support for varying the number
of service threads according to load but initially at least, nfsd uses
a fixed number of threads according to the value supplied to its '-n'
option.
