From 4c9c8d782c8dddc5e97d33210e8a993cec6bc168 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 15 Feb 2008 21:35:26 -0500 Subject: [SCSI] gdth: PCI probe cleanups, prep for PCI hotplug API conversion - Reduce uses of gdth_pci_str::pdev, preferring a local variable (or function arg) 'pdev' instead. - Reduce uses of gdth_pcistr array, preferring local variable (or function arg) 'pcistr' instead. - Eliminate lone use of gdth_pci_str::irq, using equivalent pdev->irq instead - Eliminate assign-only gdth_pci_str::io_mm Note: If the indentation seems weird, that's because a line was converted from spaces to tabs, when it was modified.

But sg can put any value in scb so the driver needs to check both the data length in the sg list and allocation length in cdb. If allocation length is larger than the response length that the driver expects, it clears the data buffer in the sg list to zero but it doesn't need to do. Just setting resid is fine.

And if we do a target reset it affects all the commands on the target so the device reset handler code only cleaning up one devices's commands makes programming the driver a little more difficult than it should be. This patch adds a target reset handler, which drivers can use to send a target reset. If successful it cleans up the commands for a devices accessed through that starget.

To simplify the code, this patch adds a new helper function to create new scsi_debug devices (sdebug_device_create) and converts both functions to use it. I plan to add more to scsi_debug devices (e.g. using a thread for a scsi_debug device for scalability testings). This patch enable me to add such to just the new helper function instead of touching two functions, sdebug_add_adapter and devInfoReg.

The problem is that SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the submitter to pick the errors out of req->errors, which the block barrier functions don't do. Since it appears that the way SG_IO and scsi_execute_request() work they discard the block error return and always use req->errors, the best fix for this is to have the SCSI layer return an error to block if one actually occurred (this also allows us to filter out spurious errors, like deferred sense). This patch is a bug fix that will need backporting to stable, but it's also quite a big change and in need of testing, so we'll incubate in the main kernel tree and backport at the -rc2 or so stage if no problems turn up.

This is catastrophic if it returns an error because the containers are part of a global list and the next action of almost every transport class is to free the memory used by the container. Fix this by making transport_container_release a void, but making it BUG if attribute_container_release returns an error ... this catches the root cause of a system panic much earlier. If we don't do this, we get an eventual BUG when the attribute container list notices the corruption caused by the freed memory it's still referencing. Also made attribute_container_release __must_check as a reminder.

Strip unused (DEBUG-ONLY) enabled functions, inlines, useless wrappers, and unused DPC flags from the code. Another step in the migration towards a cleaner (less-crusty) driver.

Now that infrastructure is present within the midlayer and there is a clear distinction between what is expected from a device and target reset, convert the current device-reset codes to a target-reset, and add codes to perform a proper device-reset (LUN reset). In the process of adding reset support, collapse and consolidate large sections of mailbox-command (TMF issuance) codes, generalize the two 'wait-for-commands-to-complete' functions, and add a generic-reset routine for use by midlayer reset functions.
