gcc hates dt < CC_DT_NONE since it can never be true when dt is an unsigned

use (unsigned)dt > CC_DT_UNKNOWN to test for bounds error since that will work
regardless of the signedness of dt.

NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are

and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for

HGST was bought by WDC. Over the years, it has sold different drives
branded as HGST, WD or WDC. All of them need the HGST workaround of
sending 4k-sized packets (or multiples of 4k). And the ones that don't
really need this aren't broken by this change. Submitter is the vendor
who has tested these changes on a number of drives. I've simplified it
slightly, since we don't need additional vendors for this at this

The -l flag sends only the READ CAPACITY (16) sevice action. Normally
we send the READ CAPACITY (10) command, and only send RC16 when the
capacity is larger than 2TB (since that's the max RC10 can
report). However, some badly programmed drives report different
numbers for RC10 and RC16. This can be hard to diagnose, but generally
there's a "Logical block address out of range" error when RC16 reports
a larger number than RC10 and the RC10 number is the correct one. By
comparing the output of readcap with and without the -l argmuent, one
can determine if there's a mismatch and if the DA_Q_NO_RC16 quirk is
needed.

Mainly focus on files that use BSD 2-Clause license, however the tool I

The Software Package Data Exchange (SPDX) group provides a specification

opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,

name and unit number in camcontrol(8).
Previously camcontrol(8) only supported rescanning or resetting
devices specified by bus:target:lun. This is because for
rescanning at least, you don't have a peripheral name and unit
number (e.g. da4) for devices that don't exist yet.
That is still the case after this change, but in other cases, when
the device does exist in the CAM EDT (Existing Device Table), we
do a careful lookup of the bus/target/lun if the user supplies a
peripheral name and unit number to find the bus:target:lun and then
issue the requested reset or rescan.
The lookup is done without actually opening the device in question,
since a rescan is often done to make a device go away after it has
been pulled. (This is especially true for busses/controllers, like
parallel SCSI controllers, that don't automatically detect changes
in topology.) Opening a device that is no longer there to
determine the bus/target/lun might result in error recovery actions
when the user really just wanted to make the device go away.
sbin/camcontrol/camcontrol.c:
In dorescan_or_reset(), if the use hasn't specified a
numeric argument, assume he has specified a device. Lookup
the pass(4) instance for that device using the transport
layer CAMGETPASSTHRU ioctl. If that is successful, we can
use the returned bus:target:lun to rescan or reset the
device.
Under the hood, resetting a device using XPT_RESET_DEV is
actually sent via the pass(4) device anyway. But this
provides a way for the user to specify devices in a more
convenient way, and can work on device rescans when the
device is going away, assuming it still exists in the EDT.
sbin/camcontrol/camcontrol.8:
Update the man page for the rescan and reset subcommands
to reflect that you can now use a device name and unit

locale, which makes the time, when reported back from the drive,
1 hour off from the intended setting. This also fixes a duplicate
day of the week ("Wednesday Wed") in the previous example.

Users can use the new generic argument, -Q task_attr, to specify a task
attribute (simple, ordered, head of queue, aca) for the commands issued.
The the default is simple, which works with all SCSI devices that support
tagged queueing.
This will mostly be useful for debugging target behavior in certain
situations.
You can try it out by compiling CTL with CTL_IO_DELAY turned on (in
sys/cam/ctl/ctl_io.h) and then do something like this with one of the CTL
LUNs:
ctladm delay 0:0 -l done -t 10
camcontrol tur da34 -v
And at then before the 10 second timer is up, in another terminal:
camcontrol inquiry da34 -Q ordered -v
The Inquiry should complete just after the TUR completes. Ordinarily
it would complete first because of the delay injection, but because the
task attribute is set to ordered in this case, CTL holds it up until the
previous command has completed.

In r307684, I changed rescan_or_reset_bus() to bzero stack-allocated CCBs
before sending them to the kernel because there was stack garbage in there
that wound up meaning that bogus CCB flags were set.
While this fixed the 'camcontrol rescan all' case (XPT_DEV_MATCH CCBs were
failing previously), it broke the 'camcontrol rescan 0' (or any other
number) case when INVARIANTS are turned on. Rescanning a single bus
reliably produced an assert in cam_periph_runccb():
panic: cam_periph_runccb: ccb=0xfffff80044ffe000, func_code=0x708, flags=0xffffdde0
The flags values don't make sense from the code. Changing the CCBs in
rescan_or_reset_bus() from stack to heap allocated avoids the problem.
It would be better to understand why userland stack allocated CCBs don't
work properly, since there may be other code that breaks if stack allocated
CCBs don't work.
