With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two. Signed-off-by: -

At the block level bidi request uses req->next_rq pointer for a second bidi_read request. At Scsi-midlayer a second scsi_data_buffer structure is used for the bidi_read part. This bidi scsi_data_buffer is put on request->next_rq->special. Struct scsi_cmnd is not changed. - Define scsi_bidi_cmnd() to return true if it is a bidi request and a second sgtable was allocated. - Define scsi_in()/scsi_out() to return the in or out scsi_data_buffer from this command This API is to isolate users from the mechanics of bidi. - Define scsi_end_bidi_request() to do what scsi_end_request() does but for a bidi request. This is necessary because bidi commands are a bit tricky here. (See comments in body) - scsi_release_buffers() will also release the bidi_read scsi_data_buffer - scsi_io_completion() on bidi commands will now call scsi_end_bidi_request() and return. - The previous work done in scsi_init_io() is now done in a new scsi_init_sgtable() (which is 99% identical to old scsi_init_io()) The new scsi_init_io() will call the above twice if needed also for the bidi_read command. Only at this point is a command bidi. - In scsi_error.c at scsi_eh_prep/restore_cmnd() make sure bidi-lld is not confused by a get-sense command that looks like bidi. This is done by puting NULL at request->next_rq, and restoring. [jejb: update to sg_table and resolve conflicts also update to blk-end-request and resolve conflicts] Signed-off-by:

In preparation for bidi we abstract all IO members of scsi_cmnd, that will need to duplicate, into a substructure. - Group all IO members of scsi_cmnd into a scsi_data_buffer structure. - Adjust accessors to new members. - scsi_{alloc,free}_sgtable receive a scsi_data_buffer instead of scsi_cmnd. And work on it. - Adjust scsi_init_io() and scsi_release_buffers() for above change. - Fix other parts of scsi_lib/scsi.c to members migration. Use accessors where appropriate. - fix Documentation about scsi_cmnd in scsi_host.h - scsi_error.c * Changed needed members of struct scsi_eh_save. * Careful considerations in scsi_eh_prep/restore_cmnd. - sd.c and sr.c * sd and sr would adjust IO size to align on device's block size so code needs to change once we move to scsi_data_buff implementation. * Convert code to use scsi_for_each_sg * Use data accessors where appropriate. - tgt: convert libsrp to use scsi_data_buffer - isd200: This driver still bangs on scsi_cmnd IO members, so need changing [jejb: rebased on top of sg_table patches fixed up conflicts and used the synergy to eliminate use_sg and sg_count] Signed-off-by: -

If we export scsi_init_io()/scsi_release_buffers() instead of scsi_{alloc,free}_sgtable() from scsi_lib than tgt code is much more insulated from scsi_lib changes. As a bonus it will also gain bidi capability when it comes. [jejb: rebase on to sg_table and fix up rejections] Signed-off-by:Andrew Morton <akpm@linux-foundation.org> Signed-off-by:

The driver only needs to check the SCB_ACTIVE flag if the SCB is not in the untagged queue. If the driver is in error recovery, you may end panic'ing on a TUR that is in the untagged queue.

The 32/64 compatibility code in the DLM does not check the validity of the lock name length passed into it, so it can easily overwrite memory if the value is rubbish (as early versions of libdlm can cause with unlock calls, it doesn't zero the field). This patch restricts the length of the name to the amount of data actually passed into the call. Signed-off-by:

To prevent the master of an rsb from changing rapidly, an unused rsb is kept on the "toss list" for a period of time to be reused. The toss list was being cleared completely for each recovery, which is unnecessary. Much of the benefit of the toss list can be maintained if nodes keep rsb's in their toss list that they are the master of. These rsb's need to be included when the resource directory is rebuilt during recovery. Signed-off-by: -

David Teigland authored
In a rare case we may need to repeat a local resource directory lookup due to a race with removing the rsb and removing the resdir record. We'll never need to do more than a single additional lookup, though, so the infinite loop around the lookup can be removed. In addition to being unnecessary, the infinite loop is dangerous since some other unknown condition may appear causing the loop to never break. Signed-off-by: -

Non-forced unlocks should be rejected if the lock is waiting on the rsb_lookup list for another lock to establish the master node. Signed-off-by: -
David Teigland authored
There was some hit and miss validation of messages that has now been cleaned up and unified. Before processing a message, the new validate_message() function checks that the lkb is the appropriate type, process-copy or master-copy, and that the message is from the correct nodeid for the the given lkb. Other checks and assertions on the lkb type and nodeid have been removed. The assertions were particularly bad since they would panic the machine instead of just ignoring the bad message. Although other recent patches have made processing old message unlikely, it still may be possible for an old message to be processed and caught by these checks. Signed-off-by: -
David Teigland authored
Messages from nodes that are no longer members of the lockspace should be ignored. When nodes are removed from the lockspace, recovery can sometimes complete quickly enough that messages arrive from a removed node after recovery has completed. When processed, these messages would often cause an error message, and could in some cases change some state, causing problems. Signed-off-by: -

When a failed request (EBADR or ENOTBLK) is unlocked/canceled instead of retried, there may be other lkb's waiting on the rsb_lookup list for it to complete. A call to confirm_master() is needed to move on to the next waiting lkb since the current one won't be retried. Signed-off-by:
