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
CAM_LUN_INVALID or CAM_TID_INVALID. Retries were being triggered
here when a umass device was unplugged, and while the retries
themselves are probably harmless, they complicated finding the real
SIM removal problems.

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.

3b87a552e4 Make the exploring of all luns supported by an HBA more of a
tunable (until we get REPORT LUNS in place).

If we're probing luns, and each probe succeeds, we keep going past
lun 7 if we're a SCSI3 or better device (until we fail to probe).

If we're probing luns, and a probe fails, we only keep going if
we're quirked *for* it (CAM_QUIRK_HILUNS), and if we're not quirked
*against* it (CAM_QUIRK_NOHILUNS), or we're a SCSI3 or better device
and the tunable (kern.cam.cam_srch_hi) is set non-zero.

6a113b3de7 Merge the dev_clone and dev_clone_cred event handlers into a single
event handler, dev_clone, which accepts a credential argument.
Implementors of the event can ignore it if they're not interested,
and most do.  This avoids having multiple event handler types and
fall-back/precedence logic in devfs.

This changes the kernel API for /dev cloning, and may affect third
party packages containg cloning kernel modules.

571dcd15e2 Fix the recent panics/LORs/hangs created by my kqueue commit by:
- Introducing the possibility of using locks different than mutexes
for the knlist locking. In order to do this, we add three arguments to
knlist_init() to specify the functions to use to lock, unlock and
check if the lock is owned. If these arguments are NULL, we assume
mtx_lock, mtx_unlock and mtx_owned, respectively.

- Using the vnode lock for the knlist locking, when doing kqueue operations
on a vnode. This way, we don't have to lock the vnode while holding a
mutex, in filt_vfsread.

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.

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).
