[PATCH] sd: fix memory corruption with broken mode page headers

2006-02-26T17:09:49Z

There's a problem in sd where we blindly believe the length of the headers and block descriptors. Some devices return insane values for these and cause our length to end up greater than the actual buffer size, so check to make sure. Signed-off-by: Al Viro Also removed the buffer size magic number (512) and added DPOFUA of zero to the defaults Signed-off-by: James Bottomley Signed-off-by: Linus Torvalds

[SCSI] always handle REQ_BLOCK_PC requests in common code

2006-01-14T16:54:45Z

LLDDs should never see REQ_BLOCK_PC requests, we can handle them just fine in the core code. There is a small behaviour change in that some check in sr's rw_intr are bypassed, but I consider the old behaviour a bug. Mike found this cleanup opportunity and provdided early patches, so all the credit goes to him, even if I redid the patches from scratch beause that was easier than forward-porting the old patches.

[SCSI] turn most scsi semaphores into mutexes

2006-01-12T17:53:11Z

the scsi layer is using semaphores in a mutex way, this patch converts these into using mutexes instead Signed-off-by: Arjan van de Ven Signed-off-by: James Bottomley

[PATCH] Add block_device_operations.getgeo block device method

2006-01-09T04:13:54Z

HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

[BLOCK] scsi: add FUA support to sd

[BLOCK] update SCSI to use new blk_ordered for barriers

2006-01-06T08:52:55Z

All ordered request related stuff delegated to HLD. Midlayer now doens't deal with ordered setting or prepare_flush callback. sd.c updated to deal with blk_queue_ordered setting. Currently, ordered tag isn't used as SCSI midlayer cannot guarantee request ordering. Signed-off-by: Tejun Heo Signed-off-by: Jens Axboe

[BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()

2006-01-06T08:49:03Z

add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

Fix up SCSI mismerge

2005-12-16T02:17:02Z

I forgot to do a git-update-cache on the merged files ...

Merge by hand (conflicts in scsi_lib.c)

2005-12-15T23:35:24Z

This merge is pretty extensive. The conflict is over the new req->retries parameter, so I had to change the prototype to scsi_setup_blk_pc_cmnd() and the usage in sd, sr and st. Signed-off-by: James Bottomley

[SCSI] Consolidate REQ_BLOCK_PC handling path (fix ipod panic)

2005-12-14T05:29:27Z

This follows on from Jens' patch and consolidates all of the ULD separate handlers for REQ_BLOCK_PC into a single call which has his fix for our direction bug. Signed-off-by: James Bottomley
