Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

I think I promised to do this two years ago This patch adds a scsi_disk class with the cache type and FUA parameters, so user land application can easily obtain them without having to parse dmesg. It also allows setting the cache type (use with care...) This patch is a bit dangerous because I've replaced the disk kref with a class device reference ...

As devfs has been disabled from the kernel tree for a number of months now (5 to be exact), here's a patch against 2.6.16-rc1-git1 that removes support for it from the SCSI subsystem.

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.

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.

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.

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.

Currently the driver takes a reference only for requests coming by way of the gendisk, not for requests coming by way of the struct device or struct scsi_device. Such requests can arrive in the rescan, flush, and shutdown pathways. The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used). This resolves Bugzilla entry #5237. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

This patch adds a delay tailored for USB flash devices that are slow to initialize their firmware. The symptom is a repeated Unit Attention with ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5 seconds for such devices to become ready. Normal devices won't send the repeated Unit Attention sense key and hence won't trigger the patch. This fixes a problem with James Roberts-Thomson's USB device, and I've seen several reports of other devices exhibiting the same symptoms -- presumably they will be helped as well.

This one removes struct scsi_request entirely from sd.

a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off c) relevant places in midlayer and sd.c taught to accept TYPE_RBC d) sd.c::sd_read_cache_type() looks into page 6 when dealing with TYPE_RBC - these guys have writeback cache flag there and are not guaranteed to have page 8 at all. e) sd_read_cache_type() got an extra sanity check - it checks that it got the page it asked for before using its contents. And screams if mismatch had happened. Rationale: there are broken devices out there that are "helpful" enough to go for "I don't have a page you've asked for, here, have another one". For example, PL3507 had been caught doing just that... f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions in there are gone now. Incidentally, I wonder if USB storage devices that have no mode page 8 are simply RBC ones. I haven't touched that, but it might be interesting to check...

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!
