b79dc8a8da Fix an issue that caused the kernel to panic inside CTL when trying
to attach to target capable HBAs that implement the old immediate
notify (XPT_IMMED_NOTIFY) and notify acknowledge (XPT_NOTIFY_ACK)
CCBs.  The new API has been in place since SVN change 196008 in
2009.

The solution is two-fold:  fix CTL to handle the responses from the
HBAs, and convert the HBA drivers in question to use the new API.

These drivers have not been tested with CTL, so how well they will
interoperate with CTL is unknown.

scsi_target.c:	Update the userland target example code to use the
		new immediate notify API.

scsi_ctl.c:	Detect when an immediate notify CCB is returned
		with CAM_REQ_INVALID or CAM_PROVIDE_FAIL status,
		and just free it.

		Fix a duplicate assignment.

aic79xx.c,
aic79xx_osm.c:	Update the aic79xx driver to use the new API.
		Target mode is not enabled on for this driver, so
		the changes will have no practical effect.

aic7xxx_osm.c:	Update the aic7xxx driver to use the new API.

sbp_targ.c:	Update the firewire target code to work with the
		new API.

mpt_cam.c:	Update the mpt(4) driver to work with the new API.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

1cc052e80f 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.

1abcdbd127 When user_frac in the polling subsystem is low it is going to busy the
CPU for too long period than necessary.  Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.

In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).

Bump __FreeBSD_version in order to signal such situation.

76ca6f88da Place hostnames and similar information fully under the prison system.
The system hostname is now stored in prison0, and the global variable
"hostname" has been removed, as has the hostname_mtx mutex.  Jails may
have their own host information, or they may inherit it from the
parent/system.  The proper way to read the hostname is via
getcredhostname(), which will copy either the hostname associated with
the passed cred, or the system hostname if you pass NULL.  The system
hostname can still be accessed directly (and without locking) at
prison0.pr_host, but that should be avoided where possible.

The "similar information" referred to is domainname, hostid, and
hostuuid, which have also become prison parameters and had their
associated global variables removed.

ebe234793b Synopsis:
If speed of link between two devices is slower than the reported max
speed of both endpoints, the current driver will fail and be unable to
negotiate.

Summary:
Test negotiated speed by reading the CSRROM into a dummy variable.
If that read fails, decrement our speed and retry.  If all else fails,
go to lowest speed possible(0).

Report speed to the user.
Add display of the Bus Info Block when debug.firewire_debug > 1
Support the Bus Info Block(1394a-2000) method of speed detection.

I also should note that I am moving "hold_count" to 0 for future

This variable determines how many bus resets to "hold" a removed
firewire device before deletion.  I don't feel this is useful and will
probably drop support for this sysctl in the future.

3042cc43f0 Some updates and bug squashing in the firewire stack.
Move the interupt handler to a driver_intr_t type function as it was trying
to do way to much for a lightweight filter interrupt function.

Introduce much more locking around fc->mtx.  Tested this for lock reversals
and other such lockups.  Locking seems to be working better, but there
is much more to do with regard to locking.  The most significant lock is
in the BUS RESET handler.  It was possible, before this checkin, to set
a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before
the code responsible for asserting BUS RESET was complete.  This locking
fixes that issue.

Move some of the memory allocations in the fc struct to the attach function
in firewire.c

Rework the businfo.generation indicator to be merely a on/off bit now.
It's purpose according to spec is to notify the bus that the config ROM
has changed.  That's it.

Catch and squash a possible panic in SBP where in the SBP_LOCK was held
during a possible error case.  The error handling code would definitely
panic as it would try to acquire the SBP_LOCK on entrance.

Catch and squash a camcontrol/device lockup when firewire drives go away.
When a firewire device was powered off or disconnected from the firewire
bus, a "camcontrol rescan all" would hang trying to poll removed devices
as they were not properly detached.  Don't do that.

Prepare for virtualization of selected SYSCTL objects by introducing a

Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).

All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
