  • 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.

  • 992b5bcee   block: no need to initialize rq->cmd with blk_get_request ... Browse Code »

    blk_get_request initializes rq->cmd (rq_init does) so the users don't
    need to do that.

    The purpose of this patch is to remove sizeof(rq->cmd) and &rq->cmd,
    as a preparation for large command support, which changes rq->cmd from
    the static array to a pointer. sizeof(rq->cmd) will not make sense and
    &rq->cmd won't work.

  • 7a85f8896   block: restore the meaning of rq->data_len to the true data length ... Browse Code »

    The meaning of rq->data_len was changed to the length of an allocated
    buffer from the true data length. It breaks SG_IO friends and
    bsg. This patch restores the meaning of rq->data_len to the true data
    length and adds rq->extra_len to store an extended length (due to
    drain buffer and padding).

    This patch also removes the code to update bio in blk_rq_map_user
    introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa.
    The commit adjusts bio according to memory alignment
    (queue_dma_alignment). However, memory alignment is NOT padding
    alignment. This adjustment also breaks SG_IO friends and bsg. Padding
    alignment needs to be fixed in a proper way (by a separate patch).

  • 6b00769fe   block: add request->raw_data_len ... Browse Code »

    With padding and draining moved into it, block layer now may extend
    requests as directed by queue parameters, so now a request has two
    sizes - the original request size and the extended size which matches
    the size of area pointed to by bios and later by sgs. The latter size
    is what lower layers are primarily interested in when allocating,
    filling up DMA tables and setting up the controller.

    Both padding and draining extend the data area to accomodate
    controller characteristics. As any controller which speaks SCSI can
    handle underflows, feeding larger data area is safe.

    So, this patch makes the primary data length field, request->data_len,
    indicate the size of full data area and add a separate length field,
    request->raw_data_len, for the unmodified request size. The latter is
    used to report to higher layer (userland) and where the original
    request size should be fed to the controller or device.

  • 44ec95425   [SCSI] sg: cap reserved_size values at max_sectors ... Browse Code »

    This patch (as857) modifies the SG_GET_RESERVED_SIZE and
    SG_SET_RESERVED_SIZE ioctls in the sg driver, capping the values at
    the device's request_queue's max_sectors value. This will permit
    cdrecord to obtain a legal value for the maximum transfer length,
    fixing Bugzilla #7026.

    The patch also caps the initial reserved_size value. There's no
    reason to have a reserved buffer larger than max_sectors, since it
    would be impossible to use the extra space.

    The corresponding ioctls in the block layer are modified similarly,
    and the initial value for the reserved_size is set as large as
    possible. This will effectively make it default to max_sectors.
    Note that the actual value is meaningless anyway, since block devices
    don't have a reserved buffer.

    Finally, the BLKSECTGET ioctl is added to sg, so that there will be a
    uniform way for users to determine the actual max_sectors value for
    any raw SCSI transport.

    The blk_rq_unmap_user() API is not very nice. It expects the caller to
    know that rq->bio has to be reset to the original bio, and it will
    silently do nothing if that is not done. Instead make it explicit that
    we need to pass in the first bio, by expecting a bio argument.

  • 097b8457d   [PATCH] scsi: clear garbage after CDBs on SG_IO ... Browse Code »

    ATAPI devices transfer fixed number of bytes for CDBs (12 or 16). Some
    ATAPI devices choke when shorter CDB is used and the left bytes contain
    garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch
    makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.

  • 21b2f0c80   [SCSI] unify SCSI_IOCTL_SEND_COMMAND implementations ... Browse Code »

    We currently have two implementations of this obsolete ioctl, one in
    the block layer and one in the scsi code. Both of them have drawbacks.

    This patch kills the scsi layer version after updating the block version
    with the missing bits:

    - argument checking
    - use scatterlist I/O
    - set number of retries based on the submitted command

    This is the last user of non-S/G I/O except for the gdth driver, so
    getting this in ASAP and through the scsi tree would be nie to kill
    the non-S/G I/O path. Jens, what do you think about adding a check
    for non-S/G I/O in the midlayer?

    Thanks to Or Gerlitz for testing this patch.

  • defd94b75   [SCSI] seperate max_sectors from max_hw_sectors ... Browse Code »

    - export __blk_put_request and blk_execute_rq_nowait
    needed for async REQ_BLOCK_PC requests
    - seperate max_hw_sectors and max_sectors for block/scsi_ioctl.c and
    SG_IO bio.c helpers per Jens's last comments. Since block/scsi_ioctl.c SG_IO was
    already testing against max_sectors and SCSI-ml was setting max_sectors and
    max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only
    prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set
    a valid max_hw_sectors for all LLDs. Today if a LLD does not set it
    SCSI-ml sets it to a safe default and some LLDs set it to a artificial low
    value to overcome memory and feedback issues.

    Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024,
    drivers that used to call blk_queue_max_sectors with a large value of
    max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.
