42aa10a9a1 After creating a filesystem using newfs -j the time stamps are all
zero and thus report as having been made in January 1970. Apart
from looking a bit silly, it also triggers alarms from scripts
that detect weird time stamps. This update sets all 4 (or 3, in
the case of UFS1) time stamps to the current time when enabling
journaling during newfs or later when enabling it with tunefs.

c78f4c8ed1 Add a "kern.features.ata_cam" sysctl in the kernel when the ATA_CAM kernel
option is defined.  This sysctl can be queried by feature_present(3).

Query for this feature in /sbin/atacontrol and /usr/sbin/burncd.
If these utilities detect that ATA_CAM is enabled, then these utilities
will error out.  These utilities are compatible with the old ATA
driver, but are incomptible with the new ATA_CAM driver.  By erroring out,
we give end-users an idea as to what remedies to use, and reduce the need for them
to file PR's.  For atacontrol, camcontrol must be used instead,
and for burncd, alternative utilties from the ports collection must be used
such as sysutils/cdrtools.

In future, maybe someone can re-write burncd to work with ATA_CAM,
but at least for now, we give a somewhat useful error message to end users.

949394e8e0 Add descriptor sense support to CAM, and honor sense residuals properly in
CAM.

Desriptor sense is a new sense data format that originated in SPC-3.  Among
other things, it allows for an 8-byte info field, which is necessary to
pass back block numbers larger than 4 bytes.

This change adds a number of new functions to scsi_all.c (and therefore
libcam) that abstract out most access to sense data.

This includes a bump of CAM_VERSION, because the CCB ABI has changed.
Userland programs that use the CAM pass(4) driver will need to be
recompiled.

camcontrol.c:	Change uses of scsi_extract_sense() to use
		scsi_extract_sense_len().

		Use scsi_get_sks() instead of accessing sense key specific
		data directly.

scsi_modes:	Update the control mode page to the latest version (SPC-4).

scsi_cmds.c,
scsi_target.c:	Change references to struct scsi_sense_data to struct
		scsi_sense_data_fixed.  This should be changed to allow the
		user to specify fixed or descriptor sense, and then use
		scsi_set_sense_data() to build the sense data.

ps3cdrom.c:	Use scsi_set_sense_data() instead of setting sense data
		manually.

cam_periph.c:	Use scsi_extract_sense_len() instead of using
		scsi_extract_sense() or accessing sense data directly.

cam_ccb.h:	Bump the CAM_VERSION from 0x15 to 0x16.  The change of
		struct scsi_sense_data from 32 to 252 bytes changes the
		size of struct ccb_scsiio, but not the size of union ccb.
		So the version must be bumped to prevent structure
		mis-matches.

scsi_all.h:	Lots of updated SCSI sense data and other structures.

		Add function prototypes for the new sense data functions.

		Take out the inline implementation of scsi_extract_sense().
		It is now too large to put in a header file.

		Add macros to calculate whether fields are present and
		filled in fixed and descriptor sense data

scsi_all.c:	In scsi_op_desc(), allow the user to pass in NULL inquiry
		data, and we'll assume a direct access device in that case.

		Changed the SCSI RESERVED sense key name and description
		to COMPLETED, as it is now defined in the spec.

		Change the error recovery action for a number of read errors
		to prevent lots of retries when the drive has said that the
		block isn't accessible.  This speeds up reconstruction of
		the block by any RAID software running on top of the drive
		(e.g. ZFS).

		In scsi_sense_desc(), allow for invalid sense key numbers.
		This allows calling this routine without checking the input
		values first.

		Change scsi_error_action() to use scsi_extract_sense_len(),
		and handle things when invalid asc/ascq values are
		encountered.

		Add a new routine, scsi_desc_iterate(), that will call the
		supplied function for every descriptor in descriptor format
		sense data.

		Add scsi_set_sense_data(), and scsi_set_sense_data_va(),
		which build descriptor and fixed format sense data.  They
		currently default to fixed format sense data.

		Add a number of scsi_get_*() functions, which get different
		types of sense data fields from either fixed or descriptor
		format sense data, if the data is present.

		Add a number of scsi_*_sbuf() functions, which print
		formatted versions of various sense data fields.  These
		functions work for either fixed or descriptor sense.

		Add a number of scsi_sense_*_sbuf() functions, which have a
		standard calling interface and print the indicated field.
		These functions take descriptors only.

		Add scsi_sense_desc_sbuf(), which will print a formatted
		version of the given sense descriptor.

		Pull out a majority of the scsi_sense_sbuf() function and
		put it into scsi_sense_only_sbuf().  This allows callers
		that don't use struct ccb_scsiio to easily utilize the
		printing routines.  Revamp that function to handle
		descriptor sense and use the new sense fetching and
		printing routines.

		Move scsi_extract_sense() into scsi_all.c, and implement it
		in terms of the new function, scsi_extract_sense_len().
		The _len() version takes a length (which should be the
		sense length - residual) and can indicate which fields are
		present and valid in the sense data.

		Add a couple of new scsi_get_*() routines to get the sense
		key, asc, and ascq only.

mly.c:		Rename struct scsi_sense_data to struct
		scsi_sense_data_fixed.

sbp_targ.c:	Use the new sense fetching routines to get sense data
		instead of accessing it directly.

sbp.c:		Change the firewire/SCSI sense data transformation code to
		use struct scsi_sense_data_fixed instead of struct
		scsi_sense_data.  This should be changed later to use
		scsi_set_sense_data().

ciss.c:		Calculate the sense residual properly.  Use
		scsi_get_sense_key() to fetch the sense key.

mps_sas.c,
mpt_cam.c:	Set the sense residual properly.

iir.c:		Use scsi_set_sense_data() instead of building sense data by
		hand.

iscsi_subr.c:	Use scsi_extract_sense_len() instead of grabbing sense data
		directly.

umass.c:	Use scsi_set_sense_data() to build sense data.

		Grab the sense key using scsi_get_sense_key().

		Calculate the sense residual properly.

isp_freebsd.h:	Use scsi_get_*() routines to grab asc, ascq, and sense key
		values.

		Calculate and set the sense residual.

2a84e78d2e Get rid of major/minor number distinction.
As of FreeBSD 6, devices can only be opened through devfs. These device
nodes don't have major and minor numbers anymore. The st_rdev field in
struct stat is simply based a copy of st_ino.

Simply display device numbers as hexadecimal, using "%#jx". This is
allowed by POSIX, since it explicitly states things like the following
(example taken from ls(1)):

	"If the file is a character special or block special file, the
	size of the file may be replaced with implementation-defined
	information associated with the device in question."

This makes the output of these commands more compact. For example, ls(1)
now uses approximately four columns less. While there, simplify the
column length calculation from ls(1) by calling snprintf() with a NULL
buffer.

Don't be afraid; if needed one can still obtain individual major/minor
numbers using stat(1).

0e6cabaab1 Fix the check in dircheck() on namlen.
The value of namlen is copied from on-disk d_namlen, which is a 8-bit
unsigned integer which can never exceed MAXNAMLEN (255) so the test is
always true.  Moreover, UFS does not allow d_namelen being zero.

Change namlen from u_int to u_int8_t, and replace the unneeded test
with a useful test.

cecff2d26e The MBR uses a 32-bit unsigned integer to store the size of a slice, but
fdisk(1) internally uses a signed int.  Should a user attempt to specify
a slice containing more than 2^31 - 1 sectors, an error will be reported
on systems with sizeof(long) == 4 and the slice size will be silently
truncated on systems with sizeof(long) > 4.

Instead use an unsigned long to store the slice size in fdisk(1).  This
allows the user to specify a slice size up to the maximum permitted by
the MBR on-disk format and does not have any problems with silent
truncation should the use specify an slice size larger than 2^32 on systems
with sizeof(long) > 4.
