Bound amount of extra data that we might touch to the max length of the compressed block and detect zero-padding in the last cluster, which when sector is all-zero might cause us to emit bogus I/O error after decompression of that fails. To not make code any more complicated that it needs to be deal with it in lazy-manner, i.e. when we first access that specific cluster. This change also fixes stupid mistake in the LZMA code, inherited from geom_lzma, which does not share length of the output buffer buffer with the decompression routine, so that in the presence of corrupted or purposedly tailored data may easily cause heap overflow and kernel memory corruption. Beef up validation of the CLOOP TOC by checking that lengths of all but the last compressed clusters match upper limit set by the decompressor and improve some error diagnostic output while I am here. 2.Add kern.geom.uzip.attach_to tunable to artifically limit attaching uzip to certain devices in the dev tree only. For example the following only makes us attaching to the GPT labels: kern.geom.uzip.attach_to="gpt/*" 3.Add kern.geom.uzip.noattach_to, which does opposite to the (2) above, i.e. prevents geom_uzip from tasting / attaching to providers matching some pattern. By default we don't attach to our own kind, i.e. kern.geom.uzip.noattach_to="*.uzip". It saves us quite some CPU cycles, esp on low-end embedded systems.

* Fix a bug that caused da(4) peripheral drivers to not fully go awayken2016-06-221-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | after the underlying device went away. The problem was that callers who queue the GEOM resize provider event didn't check to make sure that the provider had not been withered. For the other equivalent case, g_new_provider_event(), the code checks to see whether the provider has been withered before queueing a g_new_provider_event() to the event thread. In some cases, a resize provider event would come through after the provider had been withered and all of the existing consumers had been orphaned. When the resize event triggered a taste of the provider, that would attach a new consumer to the now withered provider. The wither washer (g_wither_washer() would never be able to completely tear down the GEOM because of the consumers that were hanging around. The solution was to check the G_PF_WITHER provider flag before queueing the g_resize_provider_event(), and add an assert to g_resize_provider_event() to insure that it isn't called on a withered provider. sys/geom/geom_subr.c: In g_resize_provider(), don't try to continue if the G_PF_WITHER flag is set. In g_resize_provider_event(), add an assert that the G_PF_WITHER flag is not set. In g_access(), if a provider has an error, print out the name of the provider with the error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | device is gone. The problem was that when disk_gone() is called, if the GEOM disk creation process has not yet happened, the withering process couldn't start. We didn't record any state in the GEOM disk code, and so the d_gone() callback to the da(4) driver never happened. The solution is to track the state of the creation process, and initiate the withering process from g_disk_create() if the disk is being created. This change does add fields to struct disk, and so I have bumped DISK_VERSION. geom_disk.c: Track where we are in the disk creation process, and check to see whether our underlying disk has gone away or not. In disk_gone(), set a new d_goneflag variable that g_disk_create() can check to see if it needs to clean up the disk instance. geom_disk.h: Add a mutex to struct disk (for internal use) disk init level, and a gone flag.

* Add support for managing Shingled Magnetic Recording (SMR) drives.ken2016-05-197-1/+129

This includes full management support through the GEOM BIO interface, and through a new userland utility, zonectl(8), and through camcontrol(8). This is now ready for filesystems to use to detect and manage zoned drives. (There is no work in progress that I know of to use this for ZFS or UFS, if anyone is interested, let me know and I may have some suggestions.) Also, improve ATA command passthrough and dispatch support, both via ATA and ATA passthrough over SCSI. Also, add support to camcontrol(8) for the ATA Extended Power Conditions feature set. You can now manage ATA device power states, and set various idle time thresholds for a drive to enter lower power states. Note that this change cannot be MFCed in full, because it depends on changes to the struct bio API that break compatilibity. In order to avoid breaking the stable API, only changes that don't touch or depend on the struct bio changes can be merged. For example, the camcontrol(8) changes don't depend on the new bio API, but zonectl(8) and the probe changes to the da(4) and ada(4) drivers do depend on it. Also note that the SMR changes have not yet been tested with an actual SCSI ZBC device, or a SCSI to ATA translation layer (SAT) that supports ZBC to ZAC translation. I have not yet gotten a suitable drive or SAT layer, so any testing help would be appreciated. These changes have been tested with Seagate Host Aware SATA drives attached to both SAS and SATA controllers. Also, I do not have any SATA Host Managed devices, and I suspect that it may take additional (hopefully minor) changes to support them. Thanks to Seagate for supplying the test hardware and answering questions. sbin/camcontrol/Makefile: Add epc.c and zone.c. sbin/camcontrol/camcontrol.8: Document the zone and epc subcommands. sbin/camcontrol/camcontrol.c: Add the zone and epc subcommands. Add auxiliary register support to build_ata_cmd(). Make sure to set the CAM_ATAIO_NEEDRESULT, CAM_ATAIO_DMA, and CAM_ATAIO_FPDMA flags as appropriate for ATA commands. Add a new get_ata_status() function to parse ATA result from SCSI sense descriptors (for ATA passthrough over SCSI) and ATA I/O requests. sbin/camcontrol/camcontrol.h: Update the build_ata_cmd() prototype Add get_ata_status(), zone(), and epc(). sbin/camcontrol/epc.c: Support for ATA Extended Power Conditions features. This includes support for all features documented in the ACS-4 Revision 12 specification from t13.org (dated February 18, 2016). The EPC feature set allows putting a drive into a power power mode immediately, or setting timeouts so that the drive will automatically enter progressively lower power states after various idle times. sbin/camcontrol/fwdownload.c: Update the firmware download code for the new build_ata_cmd() arguments. sbin/camcontrol/zone.c: Implement support for Shingled Magnetic Recording (SMR) drives via SCSI Zoned Block Commands (ZBC) and ATA Zoned Device ATA Command Set (ZAC). These specs were developed in concert, and are functionally identical. The primary differences are due to SCSI and ATA differences. (SCSI is big endian, ATA is little endian, for example.) This includes support for all commands defined in the ZBC and ZAC specs. sys/cam/ata/ata_all.c: Decode a number of additional ATA command names in ata_op_string(). Add a new CCB building function, ata_read_log(). Add ata_zac_mgmt_in() and ata_zac_mgmt_out() CCB building functions. These support both DMA and NCQ encapsulation. sys/cam/ata/ata_all.h: Add prototypes for ata_read_log(), ata_zac_mgmt_out(), and ata_zac_mgmt_in(). sys/cam/ata/ata_da.c: Revamp the ada(4) driver to support zoned devices. Add four new probe states to gather information needed for zone support. Add a new adasetflags() function to avoid duplication of large blocks of flag setting between the async handler and register functions. Add new sysctl variables that describe zone support and paramters. Add support for the new BIO_ZONE bio, and all of its subcommands: DISK_ZONE_OPEN, DISK_ZONE_CLOSE, DISK_ZONE_FINISH, DISK_ZONE_RWP, DISK_ZONE_REPORT_ZONES, and DISK_ZONE_GET_PARAMS. sys/cam/scsi/scsi_all.c: Add command descriptions for the ZBC IN/OUT commands. Add descriptions for ZBC Host Managed devices. Add a new function, scsi_ata_pass() to do ATA passthrough over SCSI. This will eventually replace scsi_ata_pass_16() -- it can create the 12, 16, and 32-byte variants of the ATA PASS-THROUGH command, and supports setting all of the registers defined as of SAT-4, Revision 5 (March 11, 2016). Change scsi_ata_identify() to use scsi_ata_pass() instead of scsi_ata_pass_16(). Add a new scsi_ata_read_log() function to facilitate reading ATA logs via SCSI. sys/cam/scsi/scsi_all.h: Add the new ATA PASS-THROUGH(32) command CDB. Add extended and variable CDB opcodes. Add Zoned Block Device Characteristics VPD page. Add ATA Return SCSI sense descriptor. Add prototypes for scsi_ata_read_log() and scsi_ata_pass(). sys/cam/scsi/scsi_da.c: Revamp the da(4) driver to support zoned devices. Add five new probe states, four of which are needed for ATA devices. Add five new sysctl variables that describe zone support and parameters. The da(4) driver supports SCSI ZBC devices, as well as ATA ZAC devices when they are attached via a SCSI to ATA Translation (SAT) layer. Since ZBC -> ZAC translation is a new feature in the T10 SAT-4 spec, most SATA drives will be supported via ATA commands sent via the SCSI ATA PASS-THROUGH command. The da(4) driver will prefer the ZBC interface, if it is available, for performance reasons, but will use the ATA PASS-THROUGH interface to the ZAC command set if the SAT layer doesn't support translation yet. As I mentioned above, ZBC command support is untested. Add support for the new BIO_ZONE bio, and all of its subcommands: DISK_ZONE_OPEN, DISK_ZONE_CLOSE, DISK_ZONE_FINISH, DISK_ZONE_RWP, DISK_ZONE_REPORT_ZONES, and DISK_ZONE_GET_PARAMS. Add scsi_zbc_in() and scsi_zbc_out() CCB building functions. Add scsi_ata_zac_mgmt_out() and scsi_ata_zac_mgmt_in() CCB/CDB building functions. Note that these have return values, unlike almost all other CCB building functions in CAM. The reason is that they can fail, depending upon the particular combination of input parameters. The primary failure case is if the user wants NCQ, but fails to specify additional CDB storage. NCQ requires using the 32-byte version of the SCSI ATA PASS-THROUGH command, and the current CAM CDB size is 16 bytes. sys/cam/scsi/scsi_da.h: Add ZBC IN and ZBC OUT CDBs and opcodes. Add SCSI Report Zones data structures. Add scsi_zbc_in(), scsi_zbc_out(), scsi_ata_zac_mgmt_out(), and scsi_ata_zac_mgmt_in() prototypes. sys/dev/ahci/ahci.c: Fix SEND / RECEIVE FPDMA QUEUED in the ahci(4) driver. ahci_setup_fis() previously set the top bits of the sector count register in the FIS to 0 for FPDMA commands. This is okay for read and write, because the PRIO field is in the only thing in those bits, and we don't implement that further up the stack. But, for SEND and RECEIVE FPDMA QUEUED, the subcommand is in that byte, so it needs to be transmitted to the drive. In ahci_setup_fis(), always set the the top 8 bits of the sector count register. We need it in both the standard and NCQ / FPDMA cases. sys/geom/eli/g_eli.c: Pass BIO_ZONE commands through the GELI class. sys/geom/geom.h: Add g_io_zonecmd() prototype. sys/geom/geom_dev.c: Add new DIOCZONECMD ioctl, which allows sending zone commands to disks. sys/geom/geom_disk.c: Add support for BIO_ZONE commands. sys/geom/geom_disk.h: Add a new flag, DISKFLAG_CANZONE, that indicates that a given GEOM disk client can handle BIO_ZONE commands. sys/geom/geom_io.c: Add a new function, g_io_zonecmd(), that handles execution of BIO_ZONE commands. Add permissions check for BIO_ZONE commands. Add command decoding for BIO_ZONE commands. sys/geom/geom_subr.c: Add DDB command decoding for BIO_ZONE commands. sys/kern/subr_devstat.c: Record statistics for REPORT ZONES commands. Note that the number of bytes transferred for REPORT ZONES won't quite match what is received from the harware. This is because we're necessarily counting bytes coming from the da(4) / ada(4) drivers, which are using the disk_zone.h interface to communicate up the stack. The structure sizes it uses are slightly different than the SCSI and ATA structure sizes. sys/sys/ata.h: Add many bit and structure definitions for ZAC, NCQ, and EPC command support. sys/sys/bio.h: Convert the bio_cmd field to a straight enumeration. This will yield more space for additional commands in the future. After change r297955 and other related changes, this is now possible. Converting to an enumeration will also prevent use as a bitmask in the future. sys/sys/disk.h: Define the DIOCZONECMD ioctl. sys/sys/disk_zone.h: Add a new API for managing zoned disks. This is very close to the SCSI ZBC and ATA ZAC standards, but uses integers in native byte order instead of big endian (SCSI) or little endian (ATA) byte arrays. This is intended to offer to the complete feature set of the ZBC and ZAC disk management without requiring the application developer to include SCSI or ATA headers. We also use one set of headers for ioctl consumers and kernel bio-level consumers. sys/sys/param.h: Bump __FreeBSD_version for sys/bio.h command changes, and inclusion of SMR support. usr.sbin/Makefile: Add the zonectl utility. usr.sbin/diskinfo/diskinfo.c Add disk zoning capability to the 'diskinfo -v' output. usr.sbin/zonectl/Makefile: Add zonectl makefile. usr.sbin/zonectl/zonectl.8 zonectl(8) man page. usr.sbin/zonectl/zonectl.c The zonectl(8) utility.

* Add an EARLY_AP_STARTUP option to start APs earlier during boot.jhb2016-05-141-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Application Processors (non-boot CPUs) are started by MD code at SI_SUB_CPU, but they are kept waiting in a "pen" until SI_SUB_SMP at which point they are released to run kernel threads. SI_SUB_SMP is one of the last SYSINIT levels, so APs don't enter the scheduler and start running threads until fairly late in the boot. This change moves SI_SUB_SMP up to just before software interrupt threads are created allowing the APs to start executing kernel threads much sooner (before any devices are probed). This allows several initialization routines that need to perform initialization on all CPUs to now perform that initialization in one step rather than having to defer the AP initialization to a second SYSINIT run at SI_SUB_SMP. It also permits all CPUs to be available for handling interrupts before any devices are probed. This last feature fixes a problem on with interrupt vector exhaustion. Specifically, in the old model all device interrupts were routed onto the boot CPU during boot. Later after the APs were released at SI_SUB_SMP, interrupts were redistributed across all CPUs. However, several drivers for multiqueue hardware allocate N interrupts per CPU in the system. In a system with many CPUs, just a few drivers doing this could exhaust the available pool of interrupt vectors on the boot CPU as each driver was allocating N * mp_ncpu vectors on the boot CPU. Now, drivers will allocate interrupts on their desired CPUs during boot meaning that only N interrupts are allocated from the boot CPU instead of N * mp_ncpu. Some other bits of code can also be simplified as smp_started is now true much earlier and will now always be true for these bits of code. This removes the need to treat the single-CPU boot environment as a special case. As a transition aid, the new behavior is available under a new kernel option (EARLY_AP_STARTUP). This will allow the option to be turned off if need be during initial testing. I plan to enable this on x86 by default in a followup commit in the next few days and to have all platforms moved over before 11.0. Once the transition is complete, the option will be removed along with the !EARLY_AP_STARTUP code. These changes have only been tested on x86. Other platform maintainers are encouraged to port their architectures over as well. The main things to check for are any uses of smp_started in MD code that can be simplified and SI_SUB_SMP SYSINITs in MD code that can be removed in the EARLY_AP_STARTUP case (e.g. the interrupt shuffling).

* sys/geom: spelling fixes.pfg2016-04-283-5/+5
| | | | | | These affect debugging messages. MFC after: 2 weeks
* geom: unsign some types to match their definitions and avoid overflows.pfg2016-04-275-10/+10
| | | | | | | | | | | | | | | In struct:gctl_req, nargs is unsigned. In mirror: g_mirror_syncreqs is unsigned. In raid: in struct:g_raid_volume, v_disks_count is unsigned. In virstor: in struct:g_virstor_softc, n_components is unsigned. MFC after: 2 weeks
* g_part_bsd64: Delete duplicate/dead codecem2016-04-261-2/+0
| | | | | | | | RAW_PART is handled earlier in the loop. Reported by: Coverity CID: 1223201 Sponsored by: EMC / Isilon Storage Division
* g_part_bsd64: Check for valid on-disk npartitions valuecem2016-04-261-1/+2
| | | | | | | | | | | | | | | | | This value is u32 on disk, but assigned to an int in memory. After we do the implicit conversion via assignment, check that the result is at least one[1] (non-negative[2]). 1. The subsequent for-loop iterates from gpt_entries minus one, down, until reaching zero. A negative or zero initial index results in undefined signed integer overflow. 2. It is also used to index into arrays later. In practice, we expected non-malicious disks to contain small positive values.

* sys: extend use of the howmany() macro when available.pfg2016-04-265-47/+44
| | | | | We have a howmany() macro in the <sys/param.h> header that is convenient to re-use as it makes things easier to read.
* Relax TOC offsets checking somewhat, allowing offset pointing tosobomax2016-04-261-1/+6

* o Fix handling of images with compression block sizes comparable tosobomax2016-04-231-5/+9
| | | | | | | | MAXPHYS. o Improve debug somewhat; o Convert "BUG BUG BUG message" into a proper KASSERT.
* DRY on buffer sizes. Update to r298420.asomers2016-04-211-1/+2
| | | | | | | | | | sys/geom/geom_disk.c: In disk_attr_changed, don't repeat a buffer size. Reported by: ngie, hselasky MFC after: 4 weeks X-MFC-With: 298420 Sponsored by: Spectra Logic Corp
* sys: use our roundup2/rounddown2() macros when param.h is available.pfg2016-04-212-10/+8
| | | | | | | | | | rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement. This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted.
* Notify userspace listeners when geom disk attributes have changedasomers2016-04-211-0/+4
| | | | | | | | | | sys/geom/geom_disk.c: disk_attr_changed(): Generate a devctl event of type GEOM:<attr> for every call. MFC after: 4 weeks Sponsored by: Spectra Logic Corp Differential Revision: https://reviews.freebsd.org/D5952
* Indentation issues.pfg2016-04-204-14/+7
| | | | | | Contract some lines leftover from r298310. Mea culpa.
* kernel: use our nitems() macro when it is available through param.h.pfg2016-04-194-7/+7
| | | | | | No functional change, only trivial cases are done in this sweep, Discussed in: freebsd-current
* g_gate: for pointers replace 0 with NULL.pfg2016-04-151-1/+1
| | | | | | These are mostly cosmetical, no functional change. Found with devel/coccinelle.
