  • 77c9cfc51   [SCSI] Fix printing of failed 32-byte commands ... Browse Code »

    Having the large CDB allocation logic in sd.c means that
    scsi_io_completion does not have access to the command buffer. That in
    turn causes garbage to be printed when a 32-byte command fails. Move the
    command printing to sd_done where the command buffer is intact. Clear
    the command buffer pointer after the extended CDB has been freed.

    Make scsi_print_command ignore commands with NULL CDB pointers to
    inhibit printing of garbled command strings.

  • b4567ca63   [SCSI] update scsi/constants.c ... Browse Code »

    It has been 3 years since this file was sync-ed with
    www.t10.org . Information taken from the last bunch
    of drafts released in May 2009. More asc/ascq codes
    are coming for thin provisioning; when approved and
    allocated another patch could add them prior to this
    patch going live.

    Changelog:
    - add some new command names and rename two commands
    - sync asc/ascq table with www.t10.org/lists/asc-num.txt
    - correct bug in scsi_extd_sense_format() [second
    for loop]

    for a while and we don't actually use them in the error handling.
    Remove the remaining occurrences.

  • a4dfaa6f2   [SCSI] scsi: add transport host byte errors (v3) ... Browse Code »

    Currently, if there is a transport problem the iscsi drivers will return
    outstanding commands (commands being exeucted by the driver/fw/hw) with
    DID_BUS_BUSY and block the session so no new commands can be queued.
    Commands that are caught between the failure handling and blocking are
    failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values.
    When the recovery_timeout fires, the iscsi drivers then fail IO with
    DID_NO_CONNECT.

    For fcp, some drivers will fail some outstanding IO (disk but possibly not
    tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry
    and hits the scsi_error.c failfast check, block the rport, and commands
    caught in the race are failed with DID_IMM_RETRY. Other drivers, may
    hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk
    to be called.

    The following patches attempt to unify what upper layers will see drivers
    like multipath can make a good guess. This relies on drivers being
    hooked into their transport class.

    This first patch just defines two new host byte errors so drivers can
    return the same value for when a rport/session is blocked and for
    when the fast_io_fail_tmo fires.

    The idea is that if the LLD/class detects a problem and is going to block
    a rport/session, then if the LLD wants or must return the command to scsi-ml,
    then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue
    the IO into the same scsi queue it came from, until the fast io fail timer
    fires and the class decides what to do.

    When using multipath and the fast_io_fail_tmo fires then the class
    can fail commands with DID_TRANSPORT_FAILFAST or drivers can use
    DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or
    the equivlent in iscsi if we ever implement more advanced recovery methods.
    A LLD, like lpfc, could continue to return DID_ERROR and then it will hit
    the normal failfast path, so drivers do not have fully be ported to
    work better. The point of the patches is that upper layers will
    not see a failure that could be recovered from while the rport/session is
    blocked until fast_io_fail_tmo/recovery_timeout fires.

    V3
    Remove some comments.
    V2
    Fixed patch/diff errors and renamed DID_TRANSPORT_BLOCKED to
    DID_TRANSPORT_DISRUPTED.
    V1
    initial patch.

  • db4742dd8   [SCSI] add support for variable length extended commands ... Browse Code »

    Add support for variable-length, extended, and vendor specific
    CDBs to scsi-ml. It is now possible for initiators and ULD's
    to issue these types of commands. LLDs need not change much.
    All they need is to raise the .max_cmd_len to the longest command
    they support (see iscsi patch).

    - clean-up some code paths that did not expect commands to be
    larger than 16, and change cmd_len members' type to short as
    char is not enough.

  • 75a9a4e14   [SCSI] add DID_REQUEUE string to scsi_show_result host table ... Browse Code »

    I was working on patches which add new transport error values, when I
    noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
    there is any way to hit the code path where scsi_show_result is called
    and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to
    always requeue the command. However, for completeness and because I want
    to one day send a patch that tries to add new host bytes values, I am
    sending this patch.

    scsi_print_msg() is an SPI-specific concept. This patch moves it from
    constants.c to scsi_transport_spi.c and updates the Kconfig to link in
    the SPI class for the drivers which use scsi_print_msg().

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
