  • b5aff3d27   tcm_qla2xxx: Fix residual for underrun commands that fail ... Browse Code »

    Suppose an initiator sends a DATA IN command with an allocation length
    shorter than the FC transfer length -- we get a target message like

    TARGET_CORE[qla2xxx]: Expected Transfer Length: 256 does not match SCSI CDB Length: 0 for SAM Opcode: 0x12

    In that case, the target core adjusts the data_length and sets
    se_cmd->residual_count for the underrun. But now suppose that command
    fails and we end up in tcm_qla2xxx_queue_status() -- that function
    unconditionally overwrites residual_count with the already adjusted
    data_length, and the initiator will burp with a message like

    qla2xxx [0000:00:06.0]-301d:0: Dropped frame(s) detected (0x100 of 0x100 bytes).

    Fix this by adding on to the existing underflow residual count instead.

  • 364398324   [SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routines ... Browse Code »

    The driver uses ha->mbx_cmd_flags variable to pass information between
    its ISR and mailbox routines, however, it does so without the protection of
    any locks. Under certain conditions, this can lead to multiple mailbox
    command completions being signaled, which, in turn, leads to a false
    mailbox timeout error for the subsequently issued mailbox command.

    The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz
    card during card initialization, resulting in card initialization failure.

    Pull VFS updates from Al Viro,

    Misc cleanups all over the place, mainly wrt /proc interfaces (switch
    create_proc_entry to proc_create(), get rid of the deprecated
    create_proc_read_entry() in favor of using proc_create_data() and
    seq_file etc).

    7kloc removed.

    Pull SCSI target update from Nicholas Bellinger:
    "The highlights this round include:

    - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
    - Add fileio support for UNMAP discard (asias)
    - Add tcm_vhost hotplug support to work with upstream QEMU
    vhost-scsi-pci code (asias + mst)
    - Check for aborted sequence in tcm_fc response path (mdr)
    - Add initial iscsit_transport support into iscsi-target code (nab)
    - Refactor iscsi-target RX PDU logic + export request PDU handling
    (nab)
    - Refactor iscsi-target TX queue logic + export response PDU creation
    (nab)
    - Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)

    The biggest changes revolve around iscsi-target refactoring in order
    to support the iser-target driver. This includes the conversion of
    the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
    and allowing transport independent aspects of RX/TX PDU
    request/response handling be shared across existing traditional
    iscsi-target code, and the new iser-target code.

    Thanks to Or Gerlitz + Mellanox for supporting the iser-target
    development effort!"
