ce4ba40ac9 Take CAM_REQUEUE_REQ out of the class of things we were trying to honor
retry count on.

2cd43ee6dc Clear SA_FLAG_ERR_PENDING for MTREW, MTERASE and MTRETENS ioctl cases.
Clear residual counts after a successful samount (the user doesn't
care that we got an N-kbyte residual on our test read).

Change a lot of error handling code.

1. If we end up in saerror, check more carefully about the kind of
error. If it is a CAM_SCSI_STATUS_ERROR and it is a read/write
command, we'll be handling this in saerror.  If it isn't a read/write
command, check to see whether this is just an EOM/EOP check condition-
if it is, just set residual and return normally. A residual and
then a NO SENSE check condiftion with the ASC of 0 and ASCQ of
between 1 and 4 are normal 'signifying' events, not errors per se,
and we shouldn't give the command to cam_periph_error to do something
relatively unpredictable with.

2. If we get a Bus Reset, had a BDR sent, or get the cam status of
CAM_REQUEUE_REQ, check the retry count on the command. The default
error handler, cam_periph_error, doesn't honor retry count in these
cases. This may change in the future, but for now, make sure we
set EIO and return without calling cam_periph_error if the retry
count for the command with an error is zero.

3. Clean up the pending error case goop and handle cases more
sensibly.

The rules are:

 If command was a Write:

  If we got a SSD_KEY_VOLUME_OVERFLOW, the resid is
  propagated and we set ENOSPC as the error.

  Else if we got an EOM condition- just mark EOM pending.

	And set a residual of zero. For the longest time I was just
        propagating residual from the sense data- but my tape
        comparison tests were always failing because all drives I
        tested with actually *do* write the data anyway- the EOM
        (early warning) condition occurred *prior* to all of the
        data going out to media- that is, it was still buffered by
        the drive. This case is described in SCSI-2, 10.2.14,
        paragraph #d for the meaning of 'information field'. A
        better fix for this would be to issue a WFM command of zero
        to cause the drive to flush any buffered data, but this
        would require a fairly extensive rewrite.

 Else if the command was a READ:

  If we got a SSD_KEY_BLANK_CHECK-
	If we have a One Filemark EOT model- mark EOM as pending,
	otherwise set EIO as the erorr.
  Else if we found a Filemark-
	If we're in Fixed Block mode- mark EOF pending.

 If we had an ILI (Incorrect Length Indicator)-
  If the residual is less than zero, whine about tape record
  being too big for user's buffer, otherwise if we were in
  Fixed Block mode, mark EIO as pending.

All 'pending' conditions mean that the command in question completes
without error indication. It had succeeded, but a signifying event
occurred during its execution which will apply to the *next* command
that would be exexcuted. Except for the one EOM case above, we always
propagate residual.

Now, way back in sastart- if we notice any of the PENDING bits set,
we don't run the command we've just pulled off the wait queue. Instead,
we then figure out it's disposition based upon a previous command's
association with a signifying event.

 If SA_FLAG_EOM_PENDING is set, we don't set an error. We just complete
 the command with residual set to the request count (not data moved,
 but no error). We continue on.

 If SA_FLAG_EOF_PENDING- if we have this, it's only because we're in
 Fixed Block mode- in which case we traverse all waiting buffers (which
 we can get in fixed block mode because physio has split things up) and
 mark them all as no error, but no data moved and complete them.

 If SA_FLAG_EIO_PENDING, just mark the buffer with an EIO error
 and complete it.

Then we clear all of the pending state bits- we're done.

ec7938a91d Fix the `tape drive spinning indefinately upon mt stat' problem.
With the recent changes in the CAM error handling, some problems in
the error handling of sa(4) have been uncovered.  Basically, a number
of conditions that are not actually errors have been mistreated as
genuine errors.  In particular:

. Trying to read in variable length mode with a mismatched blocksize
  between the on-tape (virtual) blocks and the read(2) supplied buffer
  size, causing an ILI SCSI condition, have caused an attempt to retry
  the supposedly `errored' transfer, causing the tape to be read
  continuously until it eventually hit EOM.  Since by default any
  simple mt(1) operation does an initial test read, an `mt stat' was
  sufficient to trigger this bug.

  Note that it's Justin's opinion that treating a NO SENSE as an EIO
  is another bug in CAM.  I feel not authorized to fix cam_periph.c
  without another confirmation that i'm on the right track, however.

. Hitting a filemark caused the read(2) syscall to return EIO, instead
  of returning a `short read'.  Note that the current fix only solves
  this problem in variable length mode.  Fixed length mode uses a
  different code path, and since i didn't grok all the intentions behind
  that handling, i did not touch it (IOW: it's still broken, and you get
  an EIO upon hitting a filemark).

The solution is to keep track of those conditions inside saerror(),
and upon completion to not call cam_periph_error() in that case.  We
need to make sure that the device gets unfrozen if needed though (in
case of actual errors, cam_periph_error() does this on our behalf).

24c4b1e75b Rewrite of the CAM error recovery code.
Some of the major changes include:

	- The SCSI error handling portion of cam_periph_error() has
	  been broken out into a number of subfunctions to better
	  modularize the code that handles the hierarchy of SCSI errors.
	  As a result, the code is now much easier to read.

	- String handling and error printing has been significantly
	  revamped.  We now use sbufs to do string formatting instead
	  of using printfs (for the kernel) and snprintf/strncat (for
	  userland) as before.

	  There is a new catchall error printing routine,
	  cam_error_print() and its string-based counterpart,
	  cam_error_string() that allow the kernel and userland
	  applications to pass in a CCB and have errors printed out
	  properly, whether or not they're SCSI errors.  Among other
	  things, this helped eliminate a fair amount of duplicate code
	  in camcontrol.

	  We now print out more information than before, including
	  the CAM status and SCSI status and the error recovery action
	  taken to remedy the problem.

	- sbufs are now available in userland, via libsbuf.  This
	  change was necessary since most of the error printing code
	  is shared between libcam and the kernel.

	- A new transfer settings interface is included in this checkin.
	  This code is #ifdef'ed out, and is primarily intended to aid
	  discussion with HBA driver authors on the final form the
	  interface should take.  There is example code in the ahc(4)
	  driver that implements the HBA driver side of the new
	  interface.  The new transfer settings code won't be enabled
	  until we're ready to switch all HBA drivers over to the new
	  interface.

src/Makefile.inc1,
lib/Makefile:		Add libsbuf.  It must be built before libcam,

libcam/Makefile:	libcam now depends on libsbuf.

libsbuf/Makefile:	Add a makefile for libsbuf.  This pulls in the
			sbuf sources from sys/kern.

bsd.libnames.mk:	Add LIBSBUF.

camcontrol/Makefile:	Add -lsbuf.  Since camcontrol is statically
			linked, we can't depend on the dynamic linker

sbuf.9:			Change the prototypes for sbuf_cat() and
			sbuf_cpy() so that the source string is now a
			const char *.  This is more in line wth the
			standard system string functions, and helps
			eliminate warnings when dealing with a const
			source buffer.

			Fix a typo.

			error status values, as well as routines to
			look up those strings.

			Add new cam_error_string() and
			cam_error_print() routines for userland and
			the kernel.

			Add enumerated types for the various options
			available with cam_error_print() and
			cam_error_string().

cam_ccb.h:		Add new transfer negotiation structures/types.

			Change inq_len in the ccb_getdev structure to
			be "reserved".  This field has never been
			filled in, and will be removed when we next
			bump the CAM version.

cam_debug.h:		Fix typo.

cam_periph.c:		Modularize cam_periph_error().  The SCSI error
			handling part of cam_periph_error() is now
			in camperiphscsistatuserror() and
			camperiphscsisenseerror().

			In cam_periph_lock(), increase the reference
			count on the periph while we wait for our lock
			attempt to succeed so that the periph won't go
			away while we're sleeping.

cam_xpt.c:		Add new transfer negotiation code.  (ifdefed
			out)

			Add a new function, xpt_path_string().  This
			is a string/sbuf analog to xpt_print_path().

scsi_all.c:		Revamp string handing and error printing code.
			We now use sbufs for much of the string
			formatting code.  More of that code is shared
			between userland the kernel.

scsi_all.h:		Get rid of SS_TURSTART, it wasn't terribly
			useful in the first place.

			Add a new error action, SS_REQSENSE.  (Send a
			request sense and then retry the command.)
			This is useful when the controller hasn't
			performed autosense for some reason.

			Change the default actions around a bit.

scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.  Selection
			timeouts shouldn't be covered by a sense flag.

scsi_pass.[ch]:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.

			Get rid of the last vestiges of a read/write
			interface.

libkern/bsearch.c,
sys/libkern.h,
conf/files:		Add bsearch.c, which is needed for some of the
			new table lookup routines.

aic7xxx_freebsd.c:	Define AHC_NEW_TRAN_SETTINGS if
			CAM_NEW_TRAN_CODE is defined.

sbuf.h,
subr_sbuf.c:		Add the appropriate #ifdefs so sbufs can
			compile and run in userland.

			Change sbuf_printf() to use vsnprintf()
			instead of kvprintf(), which is only available
			in the kernel.

			Change the source string for sbuf_cpy() and
			sbuf_cat() to be a const char *.

			Add __BEGIN_DECLS and __END_DECLS around
			function prototypes since they're now exported
			to userland.

kdump/mkioctls:		Include stdio.h before cam.h since cam.h now
			includes a function with a FILE * argument.

perhaps, of growing media defect lists in drives), but the default of
printing errors out if bootverbose in this case is probably enough.

Also, there'd been a missing ERESTART for that clause anyway.

2. If you have an ABORTED COMMAND, it's almost invariably a SCSI parity
error. You should never be silent about these since users should do something
about this if it occurs (moving that power cord *away* from the SCSI cable is
always a good first start). This should print irrespective of bootverbose
because it's an actual real error even if we retry a transmission.

437df10fdc Use the residual from a spacing operation to try and figure out where
we *really* are.

It should be noted that there is a degenerate case where soft tape
location will be lost (not causing a frozen state- but causing
the loss of reporting fileno/blockno)- that's where you backspace
over a filemark- you stop backspacing as soon as you cross the
filemark, but you have no idea what the record number now is because
you have no idea how many records you are into the file you just
backed into. Such is life.

While I'm at it, also pick up residuals from writing filemarks.

f2e5184027 Turn off the load_eject bit in cdstartunit(). It causes an `Invalid
field in CDB' error when attempting to start a caddy-type CD drive,
since those drives apparently in general refuse to load a medium.  Since
we never advertised the feature to load the medium upon calling
cdstartunit() (i. e. upon receipt of a CDIOCSTART ioctl command), nobody
should have relied on it.  Besides, nobody noticed so far at all that
this command is failing for caddy-type drives...  Only few applications
seem to use it at all (among them is workman, which made me notice it).

b1f245fc31 Fix a problem with the previous revision (1.42) that showed up with audio
CDs.

With audio CDs, you can't just do a READ(10) call on most drives without
first setting the blocksize with a mode select command.  The disklabel code
does a read of the first sector of the media to find a label if it exists.

This caused drives to return an error when an audio CD was in the drive,
due to the problem described above.

The solution is to read the table of contents on the CD, and only attempt
to read the disklabel if the first track is a data track.

This works on all the various CD and DVD media I have tried, but further
testing (especially with Video CDs and other mode 2 media) will be
needed to determine if this is a universal solution.

3096d95ce6 Write support for the cd(4) driver.
This allows writing to DVD-RAM, PD and similar drives that probe as CD
devices.  Note that these are randomly writeable devices, not
sequential-only devices like CD-R drives, which are supported by cdrecord.

Add a new flag value for dsopen(), DSO_COMPATLABEL.  The cd(4) driver now
uses this flag instead of the DSO_NOLABELS flag.  The DSO_NOLABELS always
used a "fake" disklabel for the entire disk, provided by the caller.

With the DSO_COMPATLABEL flag, dsopen() will first search the media for a
label, and if it finds a label, it will use that label.  Otherwise it will
use the fake disklabel provided by the caller.  This provides backwards
compatibility, since we will still have labels for ISO9660 media.

It also provides new functionality, since you can now have a regular BSD
disklabel on read-only media, or on writeable media (e.g. DVD-RAM).

Bruce and I both think that we should eventually (in a few years) get
away from using disklabels for ISO9660 media, and just use the whole disk
device (/dev/cd0).  At that point disklabel handling in the cd(4) driver
could follow the "normal" model, as used in the da(4) driver.

Also, clean up the path in a couple of places in cdregister().  (Thanks to
Nick Hibma for catching that bug.)
