Introduce "soft" serseq variant. With new ZFS prefetcher improvements it is no longer needed to fully serialize reads to reach decent prediction hit rate. Softer variant only creates small time window to reduce races instead of completely blocking following reads while previous is running. It much less hurts the performance in case of prediction miss.

Rework CTL frontend & backend options to use nv(3), allow creating multiple ioctl frontend ports. This revision introduces two changes to CTL: - Changes the way options are passed to CTL_LUN_REQ and CTL_PORT_REQ ioctls. Removes ctl_be_arg structure and associated logic and replaces it with nv(3)-based logic for passing in and out arguments. - Allows creating multiple ioctl frontend ports using either ctladm(8) or ctld(8). New frontend ports are represented by /dev/cam/ctl<pp>.<vp> nodes, eg /dev/cam/ctl5.3. Those device nodes respond only to CTL_IO ioctl. New command-line options for ctladm: # creates new ioctl frontend port with using free pp and vp=0 ctladm port -c # creates new ioctl frontend port with pp=10 and vp=0 ctladm port -c -O pp=10 # creates new ioctl frontend port with pp=11 and vp=12 ctladm port -c -O pp=11 -O vp=12 # removes port with number 4 (it's a "targ_port" number, not pp number) ctladm port -r -p 4 New syntax for ctl.conf: target ... { port ioctl/<pp> ... } target ... { port ioctl/<pp>/<vp> ...

Make CTL ramdisk backend a real RAM disk. If "capacity" LU option is set, ramdisk backend now implements featured thin provisioned disk, storing data in malloc(9) allocated memory blocks of pblocksize bytes (default PAGE_SIZE or 4KB). Additionally ~0.2% of LU size is used for indirection tree (bigger pblocksize reduce the overhead). Backend supports all unmap and anchor operations. If configured capacity is overflowed, proper error conditions are reported. If "capacity" LU option is not set, the backend operates mostly the same as before without allocating real storage: writes go to nowhere, reads return zeroes, reporting that all LBAs are unmapped. This backend is still mostly oriented on testing and benchmarking (it is still a volatile RAM disk), but now it should allow to run real FS tests, not only simple dumb dd. MFC after: 2 weeks

CTL LUN mapping rewrite. Replace iSCSI-specific LUN mapping mechanism with new one, working for any ports. By default all ports are created without LUN mapping, exposing all CTL LUNs as before. But, if needed, LUN mapping can be manually set on per-port basis via ctladm. For its iSCSI ports ctld does it via ioctl(2). The next step will be to teach ctld to work with FibreChannel ports also. Respecting additional flexibility of the new mechanism, ctl.conf now allows alternative syntax for LUN definition. LUNs can now be defined in global context, and then referenced from targets by unique name, as needed. It allows same LUN to be exposed several times via multiple targets. While there, increase limit for LUNs per target in ctld from 256 to 1024. Some initiators do not support LUNs above 255, but that is not our problem.

Count consecutive read requests as blocking in CTL for files and ZVOLs. Technically read requests can be executed in any order or simultaneously since they are not changing any data. But ZFS prefetcher goes crasy when it receives consecutive requests from different threads. Since prefetcher works on level of separate blocks, instead of two consecutive 128K requests it may receive 32 8K requests in mixed order. This patch is more workaround then a real fix, and it does not fix all of prefetcher problems, but it improves sequential read speed by 3-4x times in some configurations. On the other side it may hurt performance if some backing store has no prefetch, that is why it is disabled by default for raw devices. MFC after: 2 weeks

Burry devid port method, which was a gross hack. Instead make ports provide wanted port and target IDs, and LUNs provide wanted LUN IDs. After that core Device ID VPD code only had to link all of them together and add relative port and port group numbers. LUN ID for iSCSI LUNs no longer created by CTL, but by ctld, and passed to CTL as "scsiname" LUN option. This makes LUNs to report the same set of IDs, independently from the port through which it is accessed, as required by SCSI specifications.

Add the CAM Target Layer (CTL). CTL is a disk and processor device emulation subsystem originally written for Copan Systems under Linux starting in 2003. It has been shipping in Copan (now SGI) products since 2005. It was ported to FreeBSD in 2008, and thanks to an agreement between SGI (who acquired Copan's assets in 2010) and Spectra Logic in 2010, CTL is available under a BSD-style license. The intent behind the agreement was that Spectra would work to get CTL into the FreeBSD tree. Some CTL features: - Disk and processor device emulation. - Tagged queueing - SCSI task attribute support (ordered, head of queue, simple tags) - SCSI implicit command ordering support. (e.g. if a read follows a mode select, the read will be blocked until the mode select completes.) - Full task management support (abort, LUN reset, target reset, etc.) - Support for multiple ports - Support for multiple simultaneous initiators - Support for multiple simultaneous backing stores - Persistent reservation support - Mode sense/select support - Error injection support - High Availability support (1) - All I/O handled in-kernel, no userland context switch overhead. (1) HA Support is just an API stub, and needs much more to be fully functional. ctl.c: The core of CTL. Command handlers and processing, character driver, and HA support are here. ctl.h: Basic function declarations and data structures. ctl_backend.c, ctl_backend.h: The basic CTL backend API. ctl_backend_block.c, ctl_backend_block.h: The block and file backend. This allows for using a disk or a file as the backing store for a LUN. Multiple threads are started to do I/O to the backing device, primarily because the VFS API requires that to get any concurrency. ctl_backend_ramdisk.c: A "fake" ramdisk backend. It only allocates a small amount of memory to act as a source and sink for reads and writes from an initiator. Therefore it cannot be used for any real data, but it can be used to test for throughput. It can also be used to test initiators' support for extremely large LUNs. ctl_cmd_table.c: This is a table with all 256 possible SCSI opcodes, and command handler functions defined for supported opcodes. ctl_debug.h: Debugging support. ctl_error.c, ctl_error.h: CTL-specific wrappers around the CAM sense building functions. ctl_frontend.c, ctl_frontend.h: These files define the basic CTL frontend port API. ctl_frontend_cam_sim.c: This is a CTL frontend port that is also a CAM SIM. This frontend allows for using CTL without any target-capable hardware. So any LUNs you create in CTL are visible in CAM via this port. ctl_frontend_internal.c, ctl_frontend_internal.h: This is a frontend port written for Copan to do some system-specific tasks that required sending commands into CTL from inside the kernel. This isn't entirely relevant to FreeBSD in general, but can perhaps be repurposed. ctl_ha.h: This is a stubbed-out High Availability API. Much more is needed for full HA support. See the comments in the header and the description of what is needed in the README.ctl.txt file for more details. ctl_io.h: This defines most of the core CTL I/O structures. union ctl_io is conceptually very similar to CAM's union ccb. ctl_ioctl.h: This defines all ioctls available through the CTL character device, and the data structures needed for those ioctls. ctl_mem_pool.c, ctl_mem_pool.h: Generic memory pool implementation used by the internal frontend. ctl_private.h: Private data structres (e.g. CTL softc) and function prototypes. This also includes the SCSI vendor and product names used by CTL. ctl_scsi_all.c, ctl_scsi_all.h: CTL wrappers around CAM sense printing functions. ctl_ser_table.c: Command serialization table. This defines what happens when one type of command is followed by another type of command. ctl_util.c, ctl_util.h: CTL utility functions, primarily designed to be used from userland. See ctladm for the primary consumer of these functions. These include CDB building functions. scsi_ctl.c: CAM target peripheral driver and CTL frontend port. This is the path into CTL for commands from target-capable hardware/SIMs. README.ctl.txt: CTL code features, roadmap, to-do list. usr.sbin/Makefile: Add ctladm. ctladm/Makefile, ctladm/ctladm.8, ctladm/ctladm.c, ctladm/ctladm.h, ctladm/util.c: ctladm(8) is the CTL management utility. It fills a role similar to camcontrol(8). It allow configuring LUNs, issuing commands, injecting errors and various other control functions. usr.bin/Makefile: Add ctlstat. ctlstat/Makefile ctlstat/ctlstat.8, ctlstat/ctlstat.c: ctlstat(8) fills a role similar to iostat(8). It reports I/O statistics for CTL. sys/conf/files: Add CTL files. sys/conf/NOTES: Add device ctl. sys/cam/scsi_all.h: To conform to more recent specs, the inquiry CDB length field is now 2 bytes long. Add several mode page definitions for CTL. sys/cam/scsi_all.c: Handle the new 2 byte inquiry length. sys/dev/ciss/ciss.c, sys/dev/ata/atapi-cam.c, sys/cam/scsi/scsi_targ_bh.c, scsi_target/scsi_cmds.c, mlxcontrol/interface.c: Update for 2 byte inquiry length field. scsi_da.h: Add versions of the format and rigid disk pages that are in a more reasonable format for CTL. amd64/conf/GENERIC, i386/conf/GENERIC, ia64/conf/GENERIC, sparc64/conf/GENERIC: Add device ctl. i386/conf/PAE: The CTL frontend SIM at least does not compile cleanly on PAE.
