f6bde1fd05 Add a new API for allocating unit number (-like) resources.
Allocation is always lowest free unit number.

A mixed range/bitmap strategy for maximum memory efficiency.  In
the typical case where no unit numbers are freed total memory usage
is 56 bytes on i386.

malloc is called M_WAITOK but no locking is provided (yet).  A bit of
experience will be necessary to determine the best strategy.  Hopefully
a "caller provides locking" strategy can be maintained, but that may
require use of M_NOWAIT allocation and failure handling.

A userland test driver is included.

fbcd15008a While calling perror() on send() failure was useful for debugging the
if_em "wedging" problem, large numbers of perror() calls impacts send

  Correct handling of SADB_UPDATE and SADB_ADD requests.  key_align may
  split the mbuf due to use of m_pulldown.  Discarding the result because
  of this does not make sense as no subsequent code depends on the entire
  msg being linearized (only the individual pieces).  It's likely
  something else is wrong here but for now this appears to get things back

34ed91b45b Introduce a tunable to disable support for Synaptics touchpads. A number of
people have reported problems (stickyness, aiming difficulty) which is proving
difficult to fix, so this will default to disable until sometime after 5.3R.

To enable Synaptics support, set the 'hw.psm.synaptics_support=1' tunable.

009b028629 We seem to have occasions where sending an IPI takes significantly
longer than 'normal'.  The cause is still being tracked down but
in the meantime there are machines where raising IPI_RETRIES does
help - it's not just a case of the machine staying locked up longer
and then panic-ing anyway.  Several helpful folks on sparc64@ tried
a patch that helped figure out what to raise this number to.

0a752e9843 Prevent the unexpected deallocation of a page table page while performing
pmap_copy().  This entails additional locking in pmap_copy() and the
addition of a "flags" parameter to the page table page allocator for
specifying whether it may sleep when memory is unavailable.  (Already,
pmap_copy() checks the availability of memory, aborting if it is scarce.
In theory, another CPU could, however, allocate memory between
pmap_copy()'s check and the call to the page table page allocator,
causing the current thread to release its locks and sleep.  This change
makes this scenario impossible.)

3229c9302a When opening a pipe, usbd_setup_pipe() will do a usbd_clear_endpoint_stall()
to make sure the pipe is ready. Some devices apparently don't support
the clear stall command however. So what happens when you issue such
devices a clear stall command? Typically, the command just times out.
This, at least, is the behavior I've observed with two devices that
I own: a Rio600 mp3 player and a T-Mobile Sidekick II.

It used to be that after the timeout expired, the pipe open operation
would conclude and you could still access the device, with the only
negative effect being a long delay on open. But in the recent past,
someone added code to make the timeout a fatal error, thereby breaking
the ability to communicate with these devices in any way.

I don't know exactly what the right solution is for this problem:
presumeably there is some way to determine whether or not a device
supports the 'clear stall' command beyond just issuing one and waiting
to see if it times out, but I don't know what that is. So for now,
I've added a special case to the error checking code so that the
timeout is once again non-fatal, thereby letting me use my two
devices again.

d6a8d58875 Add an additional struct inpcb * argument to pfil(9) in order to enable
passing along socket information. This is required to work around a LOR with
the socket code which results in an easy reproducible hard lockup with
debug.mpsafenet=1. This commit does *not* fix the LOR, but enables us to do
so later. The missing piece is to turn the filter locking into a leaf lock
and will follow in a seperate (later) commit.

This will hopefully be MT5'ed in order to fix the problem for RELENG_5 in
forseeable future.

39d969aedf This is a small tool which will read an entire disk(partition) using
1M blocks and optionally write the read data to a file or disk.

If a read error happens, the 1M block gets put on the end of the worklist
and will be retried with 64k blocksize.

If a read error happens again, the 64k block gets put at the end of the
worklist and will be retried with single sector reads.

The program keeps trying until you stop it.

You can refresh a disk:

	recoverdisk /dev/ad1 /dev/ad1

or salvage a floppy:

	recoverdisk /dev/fd0 myfloppy.flp

ae59037978 Use generic infrastructure for the ucom driver instead of local stuff.
This changes the naming of USB serial devices to: /dev/ttyU%d and
/dev/cuaU%d for call-in and call-out devices respectively.  (Please
notice: capital 'U')

Please also note that we now have .init and .lock devices for USB
serial ports.  These are not persistent across device removal.  devd(8)
can be used to configure them on attachment time.

These changes also improve the chances of the system surviving if
the USB device is unplugged at an inconvenient time.  At least we
do not rip things apart while there are any threads in the device
driver anymore.

	Remove cdevsw, rely on the tty generic one.

	Don't make_dev(), use ttycreate() which does all the magic.

	In detach, do close procesing if we ripped things apart
	while the device was open.  Call ttyfree() once we're done
	cleaning up.

	Add generic cdevsw for tty devices.

	Add generic slave cdevsw for init/lock devices.

	Add ttypurge function which wakes up all know generic sleep
	points in the tty code, and calls into the hw-driver if it
	provides a method.

	Add ttycreate function which creates tty device and optionally
	cua device.  In both cases .init/.lock devices are created
	as well.

	Change ttygone() slightly to also call the hw driver provided
	purge routine.

	Add ttyfree() which will purge and destroy the cdevs.

	Add ttyconsole mode for setting console friendly termios
	on a port.

7b12509082 improve the mbuf m_print function.. Only pull length from pkthdr if there
is one, detect mbuf loops and stop, add an extra arg so you can only print
the first x bytes of the data per mbuf (print all if arg is -1), print
flags using %b (bitmask)...

No code in the tree appears to use m_print, and it's just a maner of adding
-1 as an additional arg to m_print to restore original behavior..

2bb980892d Arrgh. Recently I tried using ugen(4) in an application that uses
select(2), and discovered to my horror that ugen(4)'s bulk in/out support
is horribly lobotomized. Bulk transfers are done using the synchronous
API instead of the asynchronous one. This causes the following broken
behavior to occur:

- You open the bulk in/out ugen device and get a descriptor
- You create some other descriptor (socket, other device, etc...)
- You select on both the descriptors waiting until either one has
  data ready to read
- Because of ugen's brokenness, you block in usb_bulk_transfer() inside
  ugen_do_read() instead of blocking in select()
- The non-USB descriptor becomes ready for reading, but you remain blocked
  on select()
- The USB descriptor becomes ready for reading
- Only now are you woken up so that you can ready data from either
  descriptor.

The result is select() can only wake up when there's USB data pending. If
any other descriptor becomes ready, you lose: until the USB descriptor
becomes ready, you stay asleep.

The correct approach is to use async bulk transfers, so I changed
the read code to use the async bulk transfer API. I left the write
side alone for now since it's less of an issue.

Note that the uscanner driver has the same brokenness in it.
