This is an overhaul of the mode page handling in camcontrol as well as
related patches. These include:
* Mode page editting can be scripted. This involves two
things: first, if stdin is not a tty, changes are read from
stdin rather than invoking $EDITOR. Second, and more
importantly, not all modepage entries must be included in the
change set. This means that camcontrol can now gracefully handle
more intrusive editting from the $EDITOR, including removal or
rearrangement of lines. It also means that you can do stuff
like:
# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
# newfs /dev/da3
# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
* Range-checking on user-supplied input values. modeedit.c now
uses the field width specifiers to determine the maximum
allowable value for a field. If the user enters a value larger
than the maximum, it clips the value to the max and warns the
user. This also involved patching cam_cmdparse.c to be more
consistent with regards to the "count" parameter to arg_put
(previously is was the length of strings and 1 for all integral
types). The cam_cdbparse(3) man page was also updated to reflect
the revised semantics.
* In the process, I removed the 64 entry limit on mode pages (not
that we were even close to hitting that limit). This was a nice
side-effect of the other changes.
* Technically, the new mode editting functionality allows editting
of character array entries in mode pages (type 'c' or 'z'),
however since buff_encode doesn't grok them it is currently
useless.
* Camcontrol gained two new options related to mode pages: -l and
-b. The former lists all available mode pages for a given
device. The latter forces mode page display in binary format
(the default when no mode page definition was found in
scsi_modes).
* Added support for mode page names to scsi_modes. Allows names to
be displayed alongside mode numbers in the mode page
listing. Updated scsi_modes to use the new functionality. This
also adds the semicolon into the scsi_modes syntax as an
optional mode page definition terminator. This is needed to name
pages without providing a page format definition.
* Updated scsi_all.h to include a structure describing mode page
headers.
* Added $FreeBSD$ line to scsi_modes.

Implement a new camcontrol function, 'camcontrol format'.

libcam/Makefile: Add scsi_da.c to libcam for the new
scsi_format_unit() function.

camcontrol.8: Update the man page for the new format
functionality, and take out the examples section
describing how to do it with 'camcontrol cmd'.

camcontrol.c: New format functionality. Note that unlike the
rest of the camcontrol subcommands, this one is
interactive by default. Because of the potential
destructiveness of the format command, I thought
it necessary to get confirmation from the user
before spamming a disk. You can disable the
interactive behavior, and the status meter with
command line arguments.

scsi_da.c: Add the new scsi_format_unit() cdb building
function and use #ifdef _KERNEL to make this file
compile in both the kernel and userland. The
format unit function is currently only defined in
the non-kernel case, because nothing in the kernel
is using it. If that changes, it should be
un-ifdefed and compiled in both cases.

scsi_da.h: New function declaration, CDB structure and format
data structures.

Thanks to Nick Hibma for providing some valuable input on these changes.

Typo of sample command line.

Fix a typo, and get rid of the bugs section that talks about adding
different ways to specify devices. That code has been added.

Add a new device specification syntax to camcontrol. It is now possible to

camcontrol tur da5
or

Add a new device specification syntax to camcontrol. It is now possible to
do things like:

camcontrol tur da5
or
camcontrol tur 1:2:0
or
camcontrol tur 1:2

These changes are fully backwards compatible with the original device
specification syntax (-n dev -u unit), so it is possible to use either
method to specify a device now.

The device specification changes do not affect the rescan, reset or debug
commands, since by design, those commands work on a bus or bus:target:lun
basis only.

Also, shorten the default usage statement so that it fits in a 24 column
terminal. The full usage statement is still available by using the "help"
"-h" or "-?" arguments to camcontrol.

Add a number of interrelated CAM feature enhancements and bug fixes.

NOTE: These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface. A make world is recommended.

camcontrol.[c8]:
- We now support two new commands, "tags" and "negotiate".

- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related
parameters, and it allows users to set tagged openings for
a device.

- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.

- new description in the camcontrol man page of how to format a disk
- cleanup of the camcontrol inquiry command
- add support in the 'devlist' command for skipping unconfigured devices if
-v was not specified on the command line.
- make use of the new base_transfer_speed in the path inquiry CCB.
- fix CCB bzero cases

cam_xpt.c, cam_sim.[ch], cam_ccb.h:

- new flags on many CCB function codes to designate whether they're
non-immediate, use a user-supplied CCB, and can only be passed from
userland programs via the xpt device. Use these flags in the transport
layer and pass driver to categorize CCBs.

- new flag in the transport layer device matching code for device nodes
that indicates whether a device is unconfigured

- bump the CAM version from 0x10 to 0x11

- Change the CAM ioctls to use the version as their group code, so we can
force users to recompile code even when the CCB size doesn't change.

- add + fill in a new value in the path inquiry CCB, base_transfer_speed.
Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.

- Fix the set transfer settings code in the transport layer.

scsi_cd.c:

- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.

scsi_da.c:

- attach unless we get a "logical unit not supported" error

scsi_pass.c:

- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.

scsi_pass.h:

- change the CAM ioctls to use the CAM version as their group code.

adv driver:

- Allow changing the sync rate and offset separately.

adw driver

- Allow changing the sync rate and offset separately.

aha driver:

- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

ahc driver:

- Allow setting offset and sync rate separately

bt driver:

- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

NCR driver:

- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately

Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.
