2802110bd5 Fix a bug introduced with r182851 splitting tcp_mss() into
tcp_mss() and tcp_mss_update() so that tcp_mtudisc() could
re-use the same code.

In case we return early and got a metricptr to pass the hostcache
info back to the caller we need to initialize the data to a defined
state (zero it) as tcp_hc_get() would do if there was no hit.
Without that the caller would check on random stack garbage which
could lead to undefined results.

This only affected tcp_mss() if there was no routing entry for the peer,
tcp_mtudisc() was not affected.

77fbb9695c Reintroduce the snp(4) driver.
Because the TTY hooks interface was not finished when I imported the
MPSAFE TTY layer, I had to disconnect the snp(4) driver. This snp(4)
implementation has been sitting in my P4 branch for some time now.
Unfortunately it still doesn't use the same error handling as snp(4)
(returning codes through FIONREAD), but it should already be usable.

I'm committing this to SVN, hoping someone else could polish off its
rough edges. It's always better than having a broken driver sitting in
the tree.

6c6f8c89e8 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.

effcf5d59c 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.

26a604f3bc 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()).

2fb03513fc 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.

8df5c9ee67 Make the touch pad on my PowerBook G4 12" a little more usable.
For an unknown reason the touch pad of my PowerBook generates button 5
events when you operate it. This causes the adb_mouse code to convert
them to button 2 events, which is not what we want.

Add a new flag, AMS_TOUCHPAD, which is used to distinguish the touch
pad. When set, don't convert button events of unknown buttons to the
last button.

There are still three problems left with respect to user input:

- The mouse button events are not properly processed when the touch pad
  isn't touched.

- The arrow keys on the keyboard don't work inside X11.

- The power button isn't handled by the kernel, similar to the ACPI
  power button on i386/amd64.

e1f493235e Improve VFS locking:
- Implement real draining for vfs consumers by not relying on the
  mnt_lock and using instead a refcount in order to keep track of lock
  requesters.
- Due to the change above, remove the mnt_lock lockmgr because it is now
  useless.
- Due to the change above, vfs_busy() is no more linked to a lockmgr.
  Change so its KPI by removing the interlock argument and defining 2 new
  flags for it: MBF_NOWAIT which basically replaces the LK_NOWAIT of the
  old version (which was unlinked from the lockmgr alredy) and
  MBF_MNTLSTLOCK which provides the ability to drop the mountlist_mtx
  once the mnt interlock is held (ability still desired by most consumers).
- The stub used into vfs_mount_destroy(), that allows to override the
  mnt_ref if running for more than 3 seconds, make it totally useless.
  Remove it as it was thought to work into older versions.
  If a problem of "refcount held never going away" should appear, we will
  need to fix properly instead than trust on such hackish solution.
- Fix a bug where returning (with an error) from dounmount() was still
  leaving the MNTK_MWAIT flag on even if it the waiters were actually
  woken up. Just a place in vfs_mount_destroy() is left because it is
  going to recycle the structure in any case, so it doesn't matter.
- Remove the markercnt refcount as it is useless.

This patch modifies VFS ABI and breaks KPI for vfs_busy() so manpages and
__FreeBSD_version will be modified accordingly.

64f6525f93 We only allow a partial read of the first record in an audit pipe
record queue, so move the offset field from the per-record
audit_pipe_entry structure to the audit_pipe structure.

Now that we support reading more than one record at a time, add a
new summary field to audit_pipe, ap_qbyteslen, which tracks the
total number of bytes present in a pipe, and return that (minus
the current offset) via FIONREAD and kqueue's data variable for
the pending byte count rather than the number of bytes remaining
in only the first record.

Add a number of asserts to confirm that these counts and offsets
following the expected rules.

57b4089c20 Clamp the values of t_column to 5 digits in pstat -t' and show all ttys'.
We often run into these very high column numbers when we run curses
applications, because they don't print any newlines. This messes up the
table output of `pstat -t'. If these numbers get really high, they
aren't of any use to the reader anyway. Convert them to `99999' when
they run out of bounds.

c2c324d379 Reimplement the /dev/console device node.
One of the pieces of code that I had left alone during the development
of the MPSAFE TTY layer, was tty_cons.c. This file actually has two
different functions:

- It contains low-level console input/output routines (cnputc(), etc).

- It creates /dev/console and wraps all its cdevsw calls to the
  appropriate TTY.

This commit reimplements the second set of functions by moving it
directly into the TTY layer. /dev/console is now a character device node
that's basically a regular TTY, but does a lookup of `si_drv1' each time
you open it. d_write has also been changed to call log_console().
d_close() is not present, because we must make sure we don't revoke the
TTY after writing a log message to it.

Even though I'm not convinced this is in line with the future directions
of our console code, it is a good move for now. It removes recursive
locking from the top half of the TTY layer. The previous implementation
called into the TTY layer with Giant held.

I'm renaming tty_cons.c to kern_cons.c now. The code hardly contains any
TTY related bits, so we'd better give it a less misleading name.

ec4658731c Allow a read() on /dev/ams[0-9] to be interrupted.
Right now ams_read() uses cv_wait() to wait for new data to arrive on
the mouse device. This means that when you run `cat /dev/ams0', it
cannot be interrupted directly. After you press ^C, you first need to
move the mouse before cat will quit. Make this function use
cv_wait_sig(), which allows it to be interrupted directly.

6f79887fc5 Historically, /dev/auditpipe has allows only whole records to be read via
read(2), which meant that records longer than the buffer passed to read(2)
were dropped.  Instead take the approach of allowing partial reads to be
continued across multiple system calls more in the style of streaming
character device.

This means retaining a record on the per-pipe queue in a partially read
state, so maintain a current offset into the record.  Keep the record on
the queue during a read, so add a new lock, ap_sx, to serialize removal
of records from the queue by either read(2) or ioctl(2) requesting a pipe
flush.  Modify the kqueue handler to return bytes left in the current
record rather than simply the size of the current record.

It is now possible to use praudit, which used the standard FILE * buffer
sizes, to track much larger record sizes from /dev/auditpipe, such as
very long command lines to execve(2).

81bbfda754 When we drop an audit record going to and audit pipe because the audit
pipe has overflowed, drop the newest, rather than oldest, record.  This
makes overflow drop behavior consistent with memory allocation failure
leading to drop, avoids touching the consumer end of the queue from a
producer, and lowers the CPU overhead of dropping a record by dropping
before memory allocation and copying.

7e2b08356c Break out single audit_pipe_mtx into two types of locks: a global rwlock
protecting the list of audit pipes, and a per-pipe mutex protecting the
queue.

Likewise, replace the single global condition variable used to signal
delivery of a record to one or more pipes, and add a per-pipe condition
variable to avoid spurious wakeups when event subscriptions differ
across multiple pipes.

This slightly increases the cost of delivering to audit pipes, but should
reduce lock contention in the presence of multiple readers as only the
per-pipe lock is required to read from a pipe, as well as avoid
overheading when different pipes are used in different ways.

6d1fb102aa - Turn off interrupts instead of only entering a critical section
while doing the block store workaround so we restore the correct
  floating-point registers state in case of nested floating-point
  operations resulting from nested interrupts. This allows the
  VIS-based block copy/zero functions to be used on machines
  requiring this workaround. Alternatively, we could take care of
  saving the floating-point registers here, which would be more
  inefficiently though and also involves turning off interrupts.
- It turns out that the SCZ_PCI_DMA_SYNC register doesn't work
  like the TOMXMS_PCI_DMA_SYNC_PEND one (but more like the
  corresponding register in of Hummingbird and Sabre bridges)
  and writing the INO of the respective device to it causes a
  Safari bus error. However, due to the Schizo errata I-23,
  SCZ_PCI_DMA_SYNC can't be used as intended either, so remove
  consistent DMA syncing for Schzio bridges for now, which means
  that add-on cards with non-"sun4u compliant" (whatever that
  means exactly) PCI-PCI-bridges should be avoided until the
  proper workaround is implemented. [1]

9555573a49 - In GCC 4.2 __builtin_frame_address() was fixed to include the
V9 stack bias so we no longer need to add it in db_backtrace()
  and stack_capture() respectively. This also reverts r182018,
  which kludged around the resulting unaligned access.
- Sync the sun4v versions of db_trace.c and stack_machdep.c with
  the sparc64 ones and fix some style bugs.

3a67cd4520 o With the addition of HT rates the set of h/w codes has a much wider range
making the use of sc_hwmap to do direct mapping impractical.  Switch to
  indexing by the rate index instead of the rate code and adjust associated
  state and logic appropriately.  This has several benefits including
  simplification of the led code.

207c8f3843 More issues with pre-blocking:
a) Need for EEOR mode to take the min of the socket buffer size and the
    add more threshold, otherwise if you are so silly as to set a send
    buf size less than the add-more you could block forever in eeor mode.

 b) We were incorrectly using the sysctl vs the calculated value. This
    causes us to block forever if the addmore theshold is larger than
    then the socket buffer size.

9cdcbb63a2 Two inter-related bugs.
- If we send EXACTLY the size left in the send buffer
    and then send again, we end up with exactly 0 bytes and
    don't hit the pre-block code to wait for more space.
  - If we fall into the loop with our max_len == 0 (the bug
    above) we then call in to copy out the data, setup the length
    of the waiting to transmit data to 0 and call the mbuf copy routine
    which 0 indicates copy all the data to the mbuf chain.. which it
    does. This then leaves a "stuck" message on the stream queue with
    its size exactly 0 bytes but all the data there and thus nothing
    left in the uio structure. We then reach a stuck forever state
    never being able to send data.

5b1802a644 Improved IDE HDD geometry adjustment. Previous code didn't work with
certain ATA-6 drives including CF cards.

The IDE geometry of the PC98 is calculated from the drive capacity.
In addition to the algorithm in NEC BIOS, a variety of algorithms are
provided by 3'rd party boards and BIOS hacks.  This change has
implemented the three algorithms: IDE BIOS compatible mode, SCSI BIOS
compatible mode and same way as the previous version.  The tunable
machdep.ad_geom_method selects the algorithm.

I have been using this change for a year with CF cards.

6b076dc603 Default HZ value (1,000) on i386/amd64 is not very virtual machine friendly.
Due to the nature of the beast it causes lot of unproductive overhead. This
is especially bad when running SMP kernel on VMWare with several virtual
processors - idle FreeBSD guest with SMP kernel takes 150% host CPU time on my
dual-core MacBook Pro when I am enabling two virtual CPUs, making even host
not very usable. Detect when we are running in the sandbox and reduce HZ
to 10 (can be adjusted via VM_HZ in the kernel config) in such cases. This
brings host CPU usage of idle FreeBSD/SMP on two virtual processors down
to 10%.

Detect most popular VM platforms out there - VMWare, Parallels, VirtualBox
and VirtualPC.

- ATAPI DMA is broken on Marcel's Mac Mini because we need an ATA SELECT hook

  advisory but for now treat it as mandatory)
o handle an odd edge case, if there is a fixed transmit rate for 11g
