9e6461a2d8 Add an xpt_rescan function and a thread that will field
rescan requests. The purpose of this is to allow a SIM
(or other entities) to request a bus rescan and have it
then fielded in a different (process) context from the
caller.

There are probably better ways to accomplish this, but
it's a very small change that helps solve a number of
problems.

59398f700e Remove CTS_SPI_FLAGS_TAG_ENB. Nobody is using it and at least one
author can't remember why it was there.

The CTS_SCSI_FLAGS_TAG_ENB remains in place, and makes sense, and is
checked all over the place.

The CTS_SPI_FLAGS_TAG_ENB was probably an attempt to distinguish
protocol and transport tag capabilities. At the very least this can
be confusing and prone to many bugs, so let's just assume that the
transport tag case just flows from the protocol (and vice versa)
for now.

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

73cf209ffb Put a bit of hysteresis into both BUSY SCSI status returns
and CAM_RESRC_UNAVAIL returns. Delay a tunable amount for
either between retries.

This came up because the MPT IOC was returning "IOC out of
resources" for some user and this caused a CAM_RESRC_UNAVAIL
return. Putting a bit of delay between retries helped them
out.

There was some discussion that an async event should be used
to clear CAM_RESRC_UNAVAIL. That's probably a better notion
eventually.

c1c3139ed3 Add PIM_SEQSCAN for HBA misc flags and code that understands
what to do with it.

This forces us to scan targets sequentially, not in parallel.
The reason we might want to do this is that SPI negotiation
might not work right at the SIM level if we try to do it
in parallel. We *could* fix this for each SIM where this is
broken, but it's a lot harder to do that when we can simply
ask CAM to probe sequentially.

If PIM_SEQSCAN is not set (default), the original behaviour for
probing is unchanged.

LUN probing is still done in parallel for each target in either
case.

While we're at it, clean up some resource leakage for error
cases.

de8fa52e52 Incorporate the O_NONBLOCK open semantics of Linux and Solaris. This allows
an application to upon a tape (yea, even the non-control device) even if
it cannot establish a mount session. If the open cannot establish a mount
session and O_NONBLOCK was specified, the tape becomes 'open pending mount'.
All I/O operations that would require access to a tape thereafter until
a close attempt to initiate the mount session. If the mount session succeeds,
the tape driver transitions to full open state, else returns an appropriate
I/O error (ENXIO).

At the same time, add a change that remembers whether tape is being opened
read-only. If so, disallow 'write' operations like writing filemarks that
bypass the normal read-only filtering operations that happen in the write(2)
syscall.

d3ef345454 When deregistering a bus, attempt to flush out all outstanding
operations before returning. Point the bus at a dummy cam_sim
structure so that any CCBs will complete immediately with a
CAM_DEV_NOT_THERE status, and ensure that any xpt_schedule() calls
on the bus's devices will immediately call the peripheral's
periph_start() routine. Also repeat the async messages because
devices that were part of the way through being probed may appear
after the original AC_LOST_DEVICE was sent, and would otherwise
never go away.

These changes make it possible to deregister a bus and free the SIM
at most stages during bus probing without the usual crashes in
camisr(). In particular, plugging in a umass device and then
unplugging it as soon as the first probe messages appeared would
almost always result in a crash. Now the device just goes away with
a few CAM errors and all references to the CAM bus, target and
device are dropped correctly.

9a014e6f69 There should be no need to retry when the CCB status code is

a7e69e8b7d Fix a bug that caused some /dev entries to continue to exist after
the underlying drive had been hot-unplugged from the system.  Here
is a specific example.  Filesystem code had opened /dev/da1s1e.
Subsequently, the drive was hot-unplugged.  This (correctly) caused
all of the associated /dev/da1* entries to be deleted.  When the
filesystem later realized that the drive was gone it closed the
device, reducing the write-access counts to 0 on the geom providers
for da1s1e, da1s1, and da1.  This caused geom to re-taste the
providers, resulting in the devices being created again.  When the
drive was hot-plugged back in, it resulted in duplicate /dev entries
for da1s1e, da1s1, and da1.

This fix adds a new disk_gone() function which is called by CAM when a
drive goes away.  It orphans all of the providers associated with the
drive, setting an error condition of ENXIO in each one.  In addition,
we prevent a re-taste on last close for writing if an error condition
has been set in the provider.

- Using the vnode lock for the knlist locking, when doing kqueue operations

53372d3a6d Fix a problem with the cd(4) driver -- the CAMGETPASSTHRU ioctl wouldn't
succeed if there was no media in the drive.

This was broken in rev 1.72 when the media check was added to cdioctl().

For now, check the ioctl group to decide whether to check for media or not.
(We only need to check for media on CD-specific ioctls.)

df8f908079 Restore queue depth settings across tag disable events. The system often
disables tag queuing temporarily in order to allow controllers a window
to safely perform transfer negotiation with non-compliant devices.  Before
this change, CAM would restore the queue depth to the controller specified
maximum or device quirk level rather than any depth determined by reactions
to QUEUE FULL/BUSY events or an explicit user setting.

During device probe, initialize the flags field for XPT_SCAN_BUS.
The uninitialized value often confused CAM into not bothering to
issue an AC_FOUND_DEVICE async event for new devices.  The reason
this bug wasn't reported earlier is that CAM manually announces
devices after the initial system bus scans.

ef3cf714a4 Provide locking for the ccb_bioq. This allows xpt_done() to be called without
Giant held.  In camisr(), move the ccb_bioq elements to a temporary local list
and then process the elements off of that list.  This enables the list to be
processed by only taking the ccb_bioq_lock once and only for a very short
time.

ccb_bioq_lock is a leaf mutex, so it's fine to call xpt_done() with other
locks held.  This is just a very minor step in the work to lock CAM, but
it allows us to avoid some messy locking/unlock dances in certain drivers.

4379219537 Boot away another stackgap (one of the lest ones in linuxlator/i386) by
providing special version of CDIOCREADSUBCHANNEL ioctl(), which assumes that
result has to be placed into kernel space not user space. In the long run
more generic solution has to be designed WRT emulating various ioctl()s
that operate on userspace buffers, but right now there is only one such
ioctl() is emulated, so that it makes little sense.

f4322bc884 This is a somewhat imperfect means to try and bring FreeBSD forward in
its ability to automatically scan and attach luns for modern storage
which has luns in the 0..1000 range, not 0..7.

The correct thing would be to do REPORT LUNS for devices whose LUN0
version shows a version >= SCSI3, but lacking that we should be able
to search higher than LUN 7 if we're >= SCSI3 with no ill effects.

This change keeps all of the QUIRK_HILUNS quirks, obeys the QUIRK_NOLUNS,
and introduces a QUIRK_NOHILUNS which will keep searches above LUN 7
happening for devices that report >= SCSI3 compliance. I doubt the latter
will be needed, but you never know.

This allowed me to randomly scan and attach  > 500 disks at a time in
a situation where quirking for QUIRK_HILUNS wasn't practical (the
vendor id and product id changes of the virtualization changes
constantly).

709a936f1f Correct an off-by-one in the calculation of the inquiry buffer length
to request from devices during the "long inquiry" portion of our probe.
This same bug was fixed in the 4.x stream a few years ago, but the fix
was never propogated to -current.

This fix is slightly different than in -stable:

 o Use offsetof() instead of a hard coded constant so as the make
   the code more self-explainatory.

 o Round odd long inquiry lengths up so as to avoid tickling ignore
   wide residue bugs in broken parallel SCSI devices running with a
   wide transfer negotiation.

ad3b9257c2 Add locking to the kqueue subsystem. This also makes the kqueue subsystem
a more complete subsystem, and removes the knowlege of how things are
implemented from the drivers.  Include locking around filter ops, so a
module like aio will know when not to be unloaded if there are outstanding
knotes using it's filter ops.

Currently, it uses the MTX_DUPOK even though it is not always safe to
aquire duplicate locks.  Witness currently doesn't support the ability
to discover if a dup lock is ok (in some cases).
