Teach GEOM and CAM about the difference between the max "size" of r/w and delete requests.
sys/geom/geom_disk.h: - Added d_delmaxsize which represents the maximum size of individual device delete requests in bytes. This can be used by devices to inform geom of their size limitations regarding delete operations which are generally different from the read / write limits as data is not usually transferred from the host to physical device.
sys/geom/geom_disk.c: - Use new d_delmaxsize to calculate the size of chunks passed through to the underlying strategy during deletes instead of using read / write optimised values. This defaults to d_maxsize if unset (0).
- Moved d_maxsize default up so it can be used to default d_delmaxsize
sys/cam/ata/ata_da.c: - Added d_delmaxsize calculations for TRIM and CFA
sys/cam/scsi/scsi_da.c: - Added re-calculation of d_delmaxsize whenever delete_method is set.
- Added kern.cam.da.X.delete_max sysctl which allows the max size for delete requests to be limited. This is useful in preventing timeouts on devices who's delete methods are slow. It should be noted that this limit is reset then the device delete method is changed and that it can only be lowered not increased from the device max.

Implement media change notification for DA and CD removable media devices. It includes three parts: 1) Modifications to CAM to detect media media changes and report them to disk(9) layer. For modern SATA (and potentially UAS) devices it utilizes Asynchronous Notification mechanism to receive events from hardware. Active polling with TEST UNIT READY commands with 3 seconds period is used for incapable hardware. After that both CD and DA drivers work the same way, detecting two conditions: "NOT READY: Medium not present" after medium was detected previously, and "UNIT ATTENTION: Not ready to ready change, medium may have changed". First one reported to disk(9) as media removal, second as media insert/change. To reliably receive second event new AC_UNIT_ATTENTION async added to make UAs broadcasted to all periphs by generic error handling code in cam_periph_error(). 2) Modifications to GEOM core to handle media remove and change events. Media removal handled by spoiling all consumers attached to the provider. Media change event also schedules provider retaste after spoiling to probe new media. New flag G_CF_ORPHAN was added to consumers to reflect that consumer is in process of destruction. It allows retaste to create new geom instance of the same class, while previous one is still dying. 3) Modifications to some GEOM classes: DEV -- to report media change events to devd; VFS -- to handle spoiling same as orphan to prevent accessing replaced media. PART class already handles spoiling alike to orphan.

Fix a bug which causes a panic in daopen(). The panic is caused by a da(4) instance going away while GEOM is still probing it.
In this case, the GEOM disk class instance has been created by disk_create(), and the taste of the disk is queued in the GEOM event queue.
While that event is queued, the da(4) instance goes away. When the open call comes into the da(4) driver, it dereferences the freed (but non-NULL) peripheral pointer provided by GEOM, which results in a panic.
The solution is to add a callback to the GEOM disk code that is called when all of its resources are cleaned up. This is implemented inside GEOM by adding an optional callback that is called when all consumers have detached from a provider, and the provider is about to be deleted.
scsi_cd.c, scsi_da.c: In the register routine for the cd(4) and da(4) routines, acquire a reference to the CAM peripheral instance just before we call disk_create().
Use the new GEOM disk d_gone() callback to register a callback (dadiskgonecb()/cddiskgonecb()) that decrements the peripheral reference count once GEOM has finished cleaning up its resources.
In the cd(4) driver, clean up open and close behavior slightly. GEOM makes sure we only get one open() and one close call, so there is no need to set an open flag and decrement the reference count if we are not the first open.
In the cd(4) driver, use cam_periph_release_locked() in a couple of error scenarios to avoid extra mutex calls.
geom.h: Add a new, optional, providergone callback that is called when a provider is about to be deleted.
geom_disk.h: Add a new d_gone() callback to the GEOM disk interface.
Bump the DISK_VERSION to version 2. This probably should have been done after a couple of previous changes, especially the addition of the d_getattr() callback.
geom_disk.c: Add a providergone callback for the disk class, g_disk_providergone(), that calls the user's d_gone() callback if it exists.
Bump the DISK_VERSION to 2.
geom_subr.c: In g_destroy_provider(), call the providergone callback if it has been provided.
In g_new_geomf(), propagate the class's providergone callback to the new geom instance.
blkfront.c: Callers of disk_create() are supposed to pass in DISK_VERSION, not an explicit disk API version number. Update the blkfront driver to do that.
disk.9: Update the disk(9) man page to include information on the new d_gone() callback, as well as the previously added d_getattr() callback, d_descr field, and HBA PCI ID fields.

One more major cam_periph_error() rewrite to improve error handling and reporting. It includes: - removing of error messages controlled by bootverbose, replacing them with more universal and informative debugging on CAM_DEBUG_INFO level, that is now built into the kernel by default; - more close following to the arguments submitted by caller, such as SF_PRINT_ALWAYS, SF_QUIET_IR and SF_NO_PRINT; consumer knows better which errors are usual/expected at this point and which are really informative; - adding two new flags SF_NO_RECOVERY and SF_NO_RETRY to allow caller specify how much assistance it needs at this point; previously consumers controlled that by not calling cam_periph_error() at all, but that made behavior inconsistent and debugging complicated; - tuning debug messages and taken actions order to make debugging output more readable and cause-effect relationships visible; - making camperiphdone() (common device recovery completion handler) to also use cam_periph_error() in most cases, instead of own dumb code; - removing manual sense fetching code from cam_periph_error(); I was told by number of people that it is SIM obligation to fetch sense data, so this code is useless and only significantly complicates recovery logic; - making ada, da and pass driver to use cam_periph_error() with new limited recovery options to handle error recovery and debugging in common way; as one of results, CAM_REQUEUE_REQ and other retrying statuses are now working fine with pass driver, that caused many problems before. - reverting r186891 by raj@ to avoid burning few seconds in tight DELAY() loops on device probe, while device simply loads media; I think that problem may already be fixed in other way, and even if it is not, solution must be different.

cam_ccb.h: Add a new advanced information type, CDAI_TYPE_RCAPLONG, for long read capacity data.
cam_xpt_internal.h: Add a read capacity data pointer and length to struct cam_ed.
cam_xpt.c: Free the read capacity buffer when a device goes away. While we're here, make sure we don't leak memory for other malloced fields in struct cam_ed.
scsi_all.c: Update the scsi_read_capacity_16() to take a uint8_t * and a length instead of just a pointer to the parameter data structure. This will hopefully make this function somewhat immune to future changes in the parameter data.
scsi_all.h: Add some extra bit definitions to struct scsi_read_capacity_data_long, and bump up the structure size to the full size specified by SBC-3.
Change the prototype for scsi_read_capacity_16().
scsi_da.c: Register changes in read capacity data with the transport layer. This allows the transport layer to send out an async notification to interested parties. Update the dasetgeom() API.
Use scsi_extract_sense_len() instead of scsi_extract_sense().
scsi_xpt.c: Add support for the new CDAI_TYPE_RCAPLONG advanced information type.
Make sure we set the physpath pointer to NULL after freeing it. This allows blindly freeing it in the struct cam_ed destructor.
sys/param.h: Bump __FreeBSD_version from 1000005 to 1000006 to make it easier for third party drivers to determine that the read capacity data async notification is available.
camcontrol.c, mptutil/mpt_cam.c: Update these for the new scsi_read_capacity_16() argument structure.

Add BIO_DELETE support for SCSI Direct Access devices (da).
Depending on device capabilities use different methods to implement it. Currently used method can be read/set via kern.cam.da.X.delete_method sysctls. Possible values are: NONE - no provisioning support reported by the device; DISABLE - provisioning support was disabled because of errors; ZERO - use WRITE SAME (10) command to write zeroes; WS10 - use WRITE SAME (10) command with UNMAP bit set; WS16 - use WRITE SAME (16) command with UNMAP bit set; UNMAP - use UNMAP command (equivalent of the ATA DSM TRIM command). The last two methods (UNMAP and WS16) are defined by SBC specification and the UNMAP method is the most advanced one. The rest of methods I've found supported in Linux, and as soon as they were trivial to implement, then why not? Hope they will be useful in some cases.
Unluckily I have no devices properly reporting parameters of the logical block provisioning support via respective VPD pages (0xB0 and 0xB2). So all info I have/use now is the flag telling whether logical block provisioning is supported or not. As result, specific methods chosen now by trying different ones in order (UNMAP, WS16, DISABLE) and checking completion status to fallback if needed. I don't expect problems from this, as if something go wrong, it should just disable itself. It may disable even too aggressively if only some command parameter misfit.
Unlike Linux, which executes each delete with separate request, I've implemented here the same request aggregation as implemented in ada driver. Tests on SSDs I have show much better results doing it this way: above 8GB/s of the linear delete on Intel SATA SSD on LSI SAS HBA (mps).

Fix a race condition in CAM peripheral free handling, locking in the CAM XPT bus traversal code, and a number of other periph level issues.
cam_periph.h, cam_periph.c: Modify cam_periph_acquire() to test the CAM_PERIPH_INVALID flag prior to allowing a reference count to be gained on a peripheral. Callers of this function will receive CAM_REQ_CMP_ERR status in the situation of attempting to reference an invalidated periph. This guarantees that a peripheral scheduled for a deferred free will not be accessed during its wait for destruction.
Panic during attempts to drop a reference count on a peripheral that already has a zero reference count.
In cam_periph_list(), use a local sbuf with SBUF_FIXEDLEN set so that mallocs do not occur while the xpt topology lock is held, regardless of the allocation policy of the passed in sbuf.
Add a new routine, cam_periph_release_locked_buses(), that can be called when the caller already holds the CAM topology lock.
Add some extra debugging for duplicate peripheral allocations in cam_periph_alloc().
Treat CAM_DEV_NOT_THERE much the same as a selection timeout (AC_LOST_DEVICE is emitted), but forgo retries.
cam_xpt.c: Revamp the way the EDT traversal code does locking and reference counting. This was broken, since it assumed that the EDT would not change during traversal, but that assumption is no longer valid.
So, to prevent devices from going away while we traverse the EDT, make sure we properly lock everything and hold references on devices that we are using.
The two peripheral driver traversal routines should be examined. xptpdperiphtraverse() holds the topology lock for the entire time it runs. xptperiphtraverse() is now locked properly, but only holds the topology lock while it is traversing the list, and not while the traversal function is running.
The bus locking code in xptbustraverse() should also be revisited at a later time, since it is complex and should probably be simplified.
scsi_da.c: Pay attention to the return value from cam_periph_acquire().
Return 0 always from daclose() even if the disk is now gone.
Add some rudimentary error injection support.
scsi_sg.c: Fix reference counting in the sg(4) driver.
The sg driver was calling cam_periph_release() on close, but never called cam_periph_acquire() (which increments the reference count) on open.
The periph code correctly complained that the sg(4) driver was trying to decrement the refcount when it was already 0.

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.

Correct bioq_disksort so that bioq_insert_tail() offers barrier semantic. Add the BIO_ORDERED flag for struct bio and update bio clients to use it.
The barrier semantics of bioq_insert_tail() were broken in two ways:
o In bioq_disksort(), an added bio could be inserted at the head of the queue, even when a barrier was present, if the sort key for the new entry was less than that of the last queued barrier bio.
o The last_offset used to generate the sort key for newly queued bios did not stay at the position of the barrier until either the barrier was de-queued, or a new barrier (which updates last_offset) was queued. When a barrier is in effect, we know that the disk will pass through the barrier position just before the "blocked bios" are released, so using the barrier's offset for last_offset is the optimal choice.
sys/geom/sched/subr_disk.c: sys/kern/subr_disk.c: o Update last_offset in bioq_insert_tail().
o Only update last_offset in bioq_remove() if the removed bio is at the head of the queue (typically due to a call via bioq_takefirst()) and no barrier is active.
o In bioq_disksort(), if we have a barrier (insert_point is non-NULL), set prev to the barrier and cur to it's next element. Now that last_offset is kept at the barrier position, this change isn't strictly necessary, but since we have to take a decision branch anyway, it does avoid one, no-op, loop iteration in the while loop that immediately follows.
o In bioq_disksort(), bypass the normal sort for bios with the BIO_ORDERED attribute and instead insert them into the queue with bioq_insert_tail(). bioq_insert_tail() not only gives the desired command order during insertion, but also provides barrier semantics so that commands disksorted in the future cannot pass the just enqueued transaction.
sys/sys/bio.h: Add BIO_ORDERED as bit 4 of the bio_flags field in struct bio.

MFp4: Large set of CAM inprovements.
- Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs.

Separate the parallel scsi knowledge out of the core of the XPT, and modularize it so that new transports can be created.
Add a transport for SATA
Add a periph+protocol layer for ATA
Add a driver for AHCI-compliant hardware.
Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS.
The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers.
ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available.
This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options.
Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies.
The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged.

Fix a locking mistake in daopen(). If the open fails, which can happen because the media was removed, the periph would get its refcount dropped and ultimately freed before getting unlocked. This created a dangling pointer that was easy to trip over. This fixes a common source of crashes with removaable media, but problems remain and will get tracked down.

Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will use to synchornize and protect all data objects that are used for that SIM. Drivers that are not yet MPSAFE register Giant and operate as usual. RIght now, no drivers are MPSAFE, though a few will be changed in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled. The userland API has not changed, so tools like camcontrol do not need to be recompiled.

Fix a bug that caused some /dev entries to continue to exist after the underlying drive had been hot-unplugged from the system. Here is a specific example. Filesystem code had opened /dev/da1s1e. Subsequently, the drive was hot-unplugged. This (correctly) caused all of the associated /dev/da1* entries to be deleted. When the filesystem later realized that the drive was gone it closed the device, reducing the write-access counts to 0 on the geom providers for da1s1e, da1s1, and da1. This caused geom to re-taste the providers, resulting in the devices being created again. When the drive was hot-plugged back in, it resulted in duplicate /dev entries for da1s1e, da1s1, and da1.
This fix adds a new disk_gone() function which is called by CAM when a drive goes away. It orphans all of the providers associated with the drive, setting an error condition of ENXIO in each one. In addition, we prevent a re-taste on last close for writing if an error condition has been set in the provider.

Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing.
Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called.
Unfortunately, this results in a ton of "s/\./->/" changes to device drivers.
Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time:
The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT
A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future.
Manual page update to follow shortly.

Move dynamic sysctl(8) variable creation for the cd(4) and da(4) drivers out of cdregister() and daregister(), which are run from interrupt context.
The sysctl code does blocking mallocs (M_WAITOK), which causes problems if malloc(9) actually needs to sleep.
The eventual fix for this issue will involve moving the CAM probe process inside a kernel thread. For now, though, I have fixed the issue by moving dynamic sysctl variable creation for these two drivers to a task queue running in a kernel thread.
The existing task queues (taskqueue_swi and taskqueue_swi_giant) run in software interrupt handlers, which wouldn't fix the problem at hand. So I have created a new task queue, taskqueue_thread, that runs inside a kernel thread. (It also runs outside of Giant -- clients must explicitly acquire and release Giant in their taskqueue functions.)
scsi_cd.c: Remove sysctl variable creation code from cdregister(), and move it to a new function, cdsysctlinit(). Queue cdsysctlinit() to the taskqueue_thread taskqueue once we have fully registered the cd(4) driver instance.
scsi_da.c: Remove sysctl variable creation code from daregister(), and move it to move it to a new function, dasysctlinit(). Queue dasysctlinit() to the taskqueue_thread taskqueue once we have fully registered the da(4) instance.
taskqueue.h: Declare the new taskqueue_thread taskqueue, update some comments.
subr_taskqueue.c: Create the new kernel thread taskqueue. This taskqueue runs outside of Giant, so any functions queued to it would need to explicitly acquire/release Giant if they need it.
cd.4: Update the cd(4) man page to talk about the minimum command size sysctl/loader tunable. Also note that the changer variables are available as loader tunables as well.
da.4: Update the da(4) man page to cover the retry_count, default_timeout and minimum_cmd_size sysctl variables/loader tunables. Remove references to /dev/r???, they aren't used any longer.
cd.9: Update the cd(9) man page to describe the CD_Q_10_BYTE_ONLY quirk.
taskqueue.9: Update the taskqueue(9) man page to describe the new thread task queue, and the taskqueue_swi_giant queue.

This is a quick workaround for many devices (especially USB) that require da(4) quirks to operate. The more complete approach is to finish the new transport code which will be aware of the SCSI version a transport implements.

Fix three problems in large (>2TB) device handling: - Make sure we don't release the READ CAPACITY CCB twice - If we have a device that needs a 16 byte READ CAPACITY command, make sure we call xpt_schedule() so we can get a CCB. - Don't unlock the peripheral until we're fully probed.
Many thanks to Julian Elischer for providing hardware and testing this.

Fix compile errors on ia64 in dagetcapacity. Set block_len and maxsector to 0 initially. It seems that the ia64 backend isn't as "smart" as the i386 backend, which realized that those variables were only set or used when error == 0, and thus were not used uninitialized.

Add support to CAM for devices with more than 2^32 blocks. (2TB if you're using 512 byte blocks).
cam_ccb.h: Bump up volume_size and cylinders in ccb_calc_geometry to 64 bits and 32 bits respectively, so we can hold larger device sizes. cylinders would overflow at about 500GB. Bump CAM_VERSION for this change. Note that this will require a recompile of all applications that talk to the pass(4) driver.
scsi_all.c: Add descriptions for READ/WRITE(16), update READ/WRITE(12) descriptions, add descriptions for SERVICE ACTION IN/OUT. Add a new function, scsi_read_capacity_16(), that issues the read capacity service action. (Necessary for arrays larger than 2^32 sectors.) Update scsi_read_write() to use a 64 bit LBA and issue READ(16) or WRITE(16) if necessary. NOTE the API change. This should be largely transparnet to most userland applications at compile time, but will break binary compatibility. The CAM_VERSION bump, above, also serves the purpose of forcing a recompile for any applications that talk to CAM.
scsi_all.h: Add 16 byte READ/WRITE structures, structures for 16 byte READ CAPACITY/SERVICE ACTION IN. Add scsi_u64to8b() and scsi_8btou64.
scsi_da.c: The da(4) driver probe now has two stages for devices larger than 2TB. If a standard READ CAPACITY(10) returns 0xffffffff, we issue the 16 byte version of read capacity to determine the true array capacity. We also do the same thing in daopen() -- use the 16 byte read capacity if the device is large enough.
The sysctl/loader code has also been updated to accept 16 bytes as a minimum command size.

Clean up dynamically allocated sysctl variables when we run dacleanup() and cdcleanup(). This fixes sysctl problems ("can't re-use a leaf") when someone adds another peripheral at the same unit number. (e.g. rescan da0, it goes away, then rescan again and da0 comes back, but since we haven't cleaned up the sysctl variables from the last da0 instance, we can't register the variables for the new instance under the same name.)

NO_GEOM cleanup:
Retire the "d_dump_t" and use the "dumper_t" type instead.
Dumper_t takes a void * as first arg which is more general than the dev_t taken by d_dump_t. (Remember: we could have net-dumpers if somebody wrote us one!)
Define the convention for GEOM controlled disk devices to be that the first argument to the dumper function is the struct disk pointer.

Fix ATAPI/USB/Firewire CDROM drive handling in cd(4) and hopefully fix a number of related problems along the way.
- Automatically detect CDROM drives that can't handle 6 byte mode sense and mode select, and adjust our command size accordingly. We have to handle this in the cd(4) driver (where the buffers are allocated), since the parameter list length is different for the 6 and 10 byte mode sense commands.
- Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM and in the umass(4) driver, since there's no way for that to work properly.
- Add a quirk entry for CDROM drives that just hang when they get a 6 byte mode sense or mode select. The reason for the quirk must be documented in a PR, and all quirks must be approved by ken@FreeBSD.org. This is to make sure that we fully understand why each quirk is needed. Once the CAM_NEW_TRAN_CODE is finished, we should be able to remove any such quirks, since we'll know what protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether we should use 6 or 10 byte mode sense/select commands.
- Change the way the da(4) handles the no_6_byte sysctl. There is now a per-drive sysctl to set the minimum command size for that particular disk. (Since you could have multiple disks with multiple requirements in one system.)
- Loader tunable support for all the sysctls in the da(4) and cd(4) drivers.
- Add a CDIOCCLOSE ioctl for cd(4) (bde pointed this out a long time ago).
- Add a media validation routine (cdcheckmedia()) to the cd(4) driver, to fix some problems bde pointed out a long time ago. We now allow open() to succeed no matter what, but if we don't detect valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT ioctls.
- The media validation routine also reads the table of contents off the drive. We use the table of contents to implement the CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command. The PLAY AUDIO TRACK INDEX command that we previously used was deprecated after SCSI-2. It works in every SCSI CDROM I've tried, but doesn't seem to work on ATAPI CDROM drives. We still use the play audio track index command if we don't have a valid TOC, but I suppose it'll fail anyway in that case.
- Add _len() versions of scsi_mode_sense() and scsi_mode_select() so that we can specify the minimum command length.
- Fix a couple of formatting problems in the sense printing code.

Move dashutdown from SHUTDOWN_PRI_DEFAULT to SHUTDOWN_PRI_FIRST. Otherwise, the scsi devices that it is trying to issue commands to may have gone away. This is what caused shutdown to hang on ia64 systems with mpt scsi controllers. The bus system has torn down the device tree and reset the mpt controller etc, and suddenly along comes dashutdown and wants to issue a few more scsi commands.... <HANG!>
This shouldn't work on i386 either, but it seems to work solely due to luck.

(This commit touches about 15 disk device drivers in a very consistent and predictable way, and I apologize if I have gotten it wrong anywhere, getting prior review on a patch like this is not feasible, considering the number of people involved and hardware availability etc.)
If struct disklabel is the messenger: kill the messenger.
Inside struct disk we had a struct disklabel which disk drivers used to communicate certain metrics to the disklayer above (GEOM or the disk mini-layer). This commit changes this communication to use four explicit fields instead.
Amongst the benefits is that the fields do not get overwritten by wrong or bogus on-disk disklabels.
Once that is clear, <sys/disk.h> which is included in the drivers no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in, the few places that needs them, have gotten explicit #includes for them.
The disklabel inside struct disk is now only for internal use in the disk mini-layer, so instead of embedding it, we malloc it as we need it.
This concludes (modulus any mistakes) the series of disklabel related commits.
I belive it all amounts to a NOP for all the rest of you :-)

Automatically detect devices that do not support READ(6)/WRITE(6) and upgrade to using 10 byte cdbs.
As far as I tested, this works efficiently for most of the SBP-II/Firewire devices but most of the umass devices still need ad-hoc work around because umass-sim doesn't return any SCSI errors.
A sysctl nob is also added for the last resort. I hope we don't need DA_Q_NO_6_BYTE quirks anymore.

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, since libcam uses sbuf routines.
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 to pull in libsbuf.
camcontrol.c: Use cam_error_print() instead of checking for CAM_SCSI_STATUS_ERROR on every failed CCB.
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.
cam.c: Add description strings for the various CAM 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.
cam.h: Add a new CAM flag, CAM_RETRY_SELTO.
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.

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.

Implement an optimization of the VM<->pmap API. Pass vm_page_t's directly to various pmap_*() functions instead of looking up the physical address and passing that. In many cases, the first thing the pmap code was doing was going to a lot of trouble to get back the original vm_page_t, or it's shadow pv_table entry.
Inspired by: John Dyson's 1998 patches.
Also: Eliminate pv_table as a seperate thing and build it into a machine dependent part of vm_page_t. This eliminates having a seperate set of structions that shadow each other in a 1:1 fashion that we often went to a lot of trouble to translate from one to the other. (see above) This happens to save 4 bytes of physical memory for each page in the system. (8 bytes on the Alpha).
Eliminate the use of the phys_avail[] array to determine if a page is managed (ie: it has pv_entries etc). Store this information in a flag. Things like device_pager set it because they create vm_page_t's on the fly that do not have pv_entries. This makes it easier to "unmanage" a page of physical memory (this will be taken advantage of in subsequent commits).
Add a function to add a new page to the freelist. This could be used for reclaiming the previously wasted pages left over from preloaded loader(8) files.

B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.

Revamp the devstat priority system. All disks now have the same priority. The same goes for CD drivers and tape drivers. In systems with mixed IDE and SCSI, devices in the same priority class will be sorted in attach order.
Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of drivers have been modified to use that priority.
This includes the necessary changes to all drivers, except the ATA drivers. Soren will modify those separately.
This does not include and does not require any change in the devstat version number, since no known userland applications use the priority enumerations.

Add a facility in the CAM error handling code to retry selection timeouts. If the client requests that the error recovery code retry a selection timeout, it will be retried after half a second. The delay is to give the device time to recover.
For most of these drivers, I only added selection timeout retries where they were also retrying unit attention type errors. The sa(4) driver calls saerror() in a number of places, but most of them don't request retrying unit attentions.
Also, bump the default minimum CD changer timeout from 2 to 5 seconds and the maximum timeout from 10 to 15 seconds. Some Pioneer changers seem to have trouble with the shorter timeout.

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

Add a prioritization field to the devstat_add_entry() call so that peripheral drivers can determine where in the devstat(9) list they are inserted.
This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and any ports that depend on the devstat code, since the size of the devstat structure has changed. The devstat version number has been incremented as well to reflect the change.
This sorts devices in the devstat list in "more interesting" to "less interesting" order. So, for instance, da devices are now more important than floppy drives, and so will appear before floppy drives in the default output from systat, iostat, vmstat, etc.
The order of devices is, for now, kept in a central table in devicestat.h. If individual drivers were able to make a meaningful decision on what priority they should be at attach time, we could consider splitting the priority information out into the various drivers. For now, though, they have no way of knowing that, so it's easier to put them in an easy to find table.
Also, move the checkversion() call in vmstat(8) to a more logical place.
Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and for putting up with the long time it has taken me to commit it. Bruce did object somewhat to the central priority table (he would rather the priorities be distributed in each driver), so his objection is duly noted here.

"Fix" a problem with the Quantum Viking. It appears that this drive does not like the 6-byte read and write commands! It returns illegal request, with the field pointer pointing to byte 9 of a 6 byte CDB.
In any case, the work around is to put in a quirk mechanism that makes sure that we don't send 6-byte reads or writes to this device. It's rather sad that this is necessary. You'd think that they would be able to get something that basic to work right in their firmware...

Fix a problem with the way we handled device invalidation when attaching to a device failed.
In theory, the same steps that happen when we get an AC_LOST_DEVICE async notification should have been taken when a driver fails to attach. In practice, that wasn't the case.
This only affected the da, cd and ch drivers, but the fix affects all peripheral drivers.
There were several possible problems: - In the da driver, we didn't remove the peripheral's softc from the da driver's linked list of softcs. Once the peripheral and softc got removed, we'd get a kernel panic the next time the timeout routine called dasendorderedtag(). - In the da, cd and possibly ch drivers, we didn't remove the peripheral's devstat structure from the devstat queue. Once the peripheral and softc were removed, this could cause a panic if anyone tried to access device statistics. (one component of the linked list wouldn't exist anymore) - In the cd driver, we didn't take the peripheral off the changer run queue if it was scheduled to run. In practice, it's highly unlikely, and maybe impossible that the peripheral would have been on the changer run queue at that stage of the probe process.
The fix is: - Add a new peripheral callback function (the "oninvalidate" function) that is called the first time cam_periph_invalidate() is called for a peripheral.
- Create new foooninvalidate() routines for each peripheral driver. This routine is always called at splsoftcam(), and contains all the stuff that used to be in the AC_LOST_DEVICE case of the async callback handler.
- Move the devstat cleanup call to the destructor/cleanup routines, since some of the drivers do I/O in their close routines.
- Make sure that when we're flushing the buffer queue, we traverse it at splbio().
- Add a check for the invalid flag in the pt driver's open routine.

Fixed two potentially serious classes of bugs:
1) The vnode pager wasn't properly tracking the file size due to "size" being page rounded in some cases and not in others. This sometimes resulted in corrupted files. First noticed by Terry Lambert. Fixed by changing the "size" pager_alloc parameter to be a 64bit byte value (as opposed to a 32bit page index) and changing the pagers and their callers to deal with this properly. 2) Fixed a bogus type cast in round_page() and trunc_page() that caused some 64bit offsets and sizes to be scrambled. Removing the cast required adding casts at a few dozen callers. There may be problems with other bogus casts in close-by macros. A quick check seemed to indicate that those were okay, however.

Add quirk entries to disable the synchronize cache command for Micropolis 2217's (reported by Matthew Jacob in NetBSD PR kern/6027) and Fujitsu M2954's (reported by Tom Jackson).
Some of the Fujitsus at least hang when they get a cache sync command. (Others just return illegal request.)
Also, make error printing in dashutdown() a little more selective. Don't print any error when the sense key is illegal request. Drives that don't support the synchronize cache command usually return illegal request. Also, make sure the scsi status is check condition before going into scsi_sense_print().

Add the quirk entry framework to handle disabling the synchronize cache command on drives that don't like it. Right now, there's just a bogus quirk entry in the table that doesn't do anything, but that should be changed once we get actual inquiry data for drives that don't like the synchronize cache command.
Also, add a shutdown hook that runs through all direct access peripherals and runs a synchronize cache on them if they're still open, and if synchronize cache isn't disabled via a quirk entry.
Add a synchronize cache call at the end of dadump() (again, conditionalized on the quirk entry), so we can insure that the disk cache contents get flushed to physical media after a dump.
Check the new quirk entry in daclose() to decide whether or not to synchronize the cache for a disk at final close.

Up the read capacity timeout from 20 seconds to 60 seconds to keep my JAZ drive happy. This shouldn't impact fast drives, and will keep cam from failing on very slow ones (that are spinning up, say). 20 seconds was almost long enough, but not in all cases.

Some fixes for the CD and DA drivers from bde. (and some of my own as well) Among them:
[ cd driver ] 1. Old labeling code was still there. 2. Error handling for dsopen() was broken (no test for the `error' returned by dsopen(); bogus test of an `error' that is known to be 0). 3. cdopen() closed the physical device after certain errors although there may still be open partitions on it. 4. cdclose() closed the physical device although there may still be open partitions on it. 5. Some printf format fixes was incomplete or missing. 6. cdioctl() truncated unit numbers mod 256. 7. cdioctl() was missing locking.
[ da driver ] 1. daclose() closed the physical device although there may still be open partitions on it. This was fixed many years ago in sd.c rev.1.57. 2. A minor optimization (the dk_slices != NULL test) in sdopen() became uglier in daopen(). It is not worth doing. da only regressed compared with od and my version of sd, since I never committed the change to sd. daopen() should probably do less if some partition is already open. This is not addressed by the diffs. [ ... ] 5. "opt_hw_wdog.h" was not included, so the HW_WDOG code was unreachable.
- Added a getdev CCB call in the cdopen() and daopen() calls so that the vendor name and device name are available for the disklabel. (suggested by bde)
- Removed vestigal devfs support in both drivers, since we can't properly work with devfs yet. (ask bde for details on this)
- Cleaned up the probe code in both drivers in the failure cases. There were a number of things wrong here. The peripheral driver instances weren't getting properly cleaned up. Sometimes the wrong probe message would get printed out (with the failure message appended), so it wasn't very clear that we failed to attach. SCSI sense information was printed, even when the error in question wasn't a SCSI error. I put similar fixes into the changer driver in revision 1.2 of scsi_ch.c.

Don't invalidate devices due to unexpected unit attention errors. In a perfect world, we'd notice the UA and do some device validation to ensure that the device hasn't changed. We may get this before the year ends, but not before 3.0R. This change gives the adminstrator ample ammunition to take off a foot or two, but hey this *is* UN*X.

Fix the CAM code so that people can compile kernels with the CD driver but without the DA driver.
The problem was that the CD driver depended on scsi_read_write() and scsi_start_stop(), which were defined in scsi_da.c.
I moved both functions, and their associated data structures and defines from scsi_da.* to scsi_all.*. This is technically the "wrong" thing to do since those commands are really only for direct-access type devices, not for all SCSI devices. I think, though, that the advantage (allowing people to compile kernels without the disk driver) outweighs any architectural purity arguments.
