  • 9c58b7ddd   target: Simplify fabric sense data length handling ... Browse Code »

    Every fabric driver has to supply a se_tfo->set_fabric_sense_len()
    method, just so iSCSI can return an offset of 2. However, every fabric
    driver is already allocating a sense buffer and passing it into the
    target core, either via transport_init_se_cmd() or target_submit_cmd().

    So instead of having iSCSI pass the start of its sense buffer into the
    core and then later tell the core to skip the first 2 bytes, it seems
    easier for iSCSI just to do the offset of 2 when it passes the sense
    buffer into the core. Then we can drop the se_tfo->set_fabric_sense_len()
    everywhere, and just add a couple of lines of code to iSCSI to set the
    sense data length to the beginning of the buffer right before it sends
    it over the network.

    (nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops +
    change transport_get_sense_buffer to follow v3.6-rc6 code w/o
    ->set_fabric_sense_len usage)

  • 2ed772b7b   target: Remove unused target_core_fabric_ops.get_fabric_sense_len method ... Browse Code »

    There are no callers of se_tfo->get_fabric_sense_len(), so we should
    stop having every fabric driver implement it.

  • ced38c8c0   target: tcm_mod_builder: small fixups ... Browse Code »

    This includes:
    - remove on _ in "__NAMELEN" in $fabric _make_tport
    - target_fabric_configfs_init() returns an error pointer and not NULL
    anymore. Consider that.
    - replace (!(var_name)) with (!var_name). The extra () are not required
    - remove #ifdef MODULE. If the code is builtin it needs an init function
    or the code is useless
    - put exit/clean functions into __exit

  • 77271de64   Documentation/target: Fix tcm_mod_builder.py build breakage ... Browse Code »

    This patch fixes TFO->release_cmd() and removes legacy pack_lun() usage
    and new_cmd_failure when generating new TCM fabric skeleton from the
    tcm_mod_builder.py script.

  • c4795fb20   target: header reshuffle, part2 ... Browse Code »

    This reorganized the headers under include/target into:

    - target_core_base.h stays as is with all target-wide data stuctures and defines
    - target_core_backend.h contains the whole interface to I/O backends
    - target_core_fabric.h contains the whole interface to fabric modules

    Except for those only the various configfs macro headers stay around.

    This patch adds the missing core_tpg_del_initiator_node_acl() call required
    by fabric modules for struct se_node_acl->acl_group context shutdown via

    target_core_fabric_configfs.c:target_fabric_nacl_base_release() ->

    struct target_core_fabric_ops->fabric_drop_nodeacl()

    for tcm_mod_builder.py generated $FABRIC_MOD_configfs.c skeleton code.

  • 10635c8b7   [SCSI] target: tcm_mod_builder.py generated Makefile cleanups ... Browse Code »

    This patch converts the tcm_mod_builder.py generation script to
    create a new drivers/target/$TCM_FABRIC_MOD/Makefile and update
    drivers/target/Makefile, instead of creating+updating a 'Kbuild'
    filename.

    It also removes the remaining EXTRA_CFLAGS includes from
    tcm_mod_build_kbuild(), and converts fabric module generated .c
    code to us ""-style includes for $FABRIC_MOD_[base,fabric].h

  • c66ac9db8   [SCSI] target: Add LIO target core v4.0.0-rc6 ... Browse Code »

    LIO target is a full featured in-kernel target framework with the
    following feature set:

    High-performance, non-blocking, multithreaded architecture with SIMD
    support.

    Advanced SCSI feature set:

    * Persistent Reservations (PRs)
    * Asymmetric Logical Unit Assignment (ALUA)
    * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S)
    * Full Error Recovery (ERL=0,1,2)
    * Active/active task migration and session continuation (ERL=2)
    * Thin LUN provisioning (UNMAP and WRITE_SAMExx)

    Multiprotocol target plugins

    Storage media independence:

    * Virtualization of all storage media; transparent mapping of IO to LUNs
    * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB
    * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc.

    Standards compliance:

    * Full compliance with IETF (RFC 3720)
    * Full implementation of SPC-4 PRs and ALUA

    Significant code cleanups done by Christoph Hellwig.

    [jejb: fix up for new block bdev exclusive interface. Minor fixes from
    Randy Dunlap and Dan Carpenter.]
