| * [PATCH] sata_sil: implement R_ERR on DMA activate FIS errata fixTejun Heo2006-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Silicon Image has disclosed a new sil3114/3152 errata and workaround which causes the controller to return R_ERR on DMA activate FIS if the FIS is received while the next PRD is being fetched. This patch implements the workaround. This errata results in lock up and doesn't trigger if m15w workaround is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1 which makes 3512/3114 lock up with some drives on all kernel versions since 2.6.14-rc1 upto now (2.6.16-rc4). This patch should fix the regression. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* | [PATCH] sd: fix memory corruption with broken mode page headersAl Viro2006-02-26
|/ | | | | | | | | | | | | | | 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.

* [PATCH] libata: fix WARN_ON() condition in *_fill_sg()Tejun Heo2006-02-20
| | | | | | | | | | | | | For ATAPI commands, padding can reduce qc->n_elem by one and thus to zero making assert(qc->n_elem > 0)'s in ata_fill_sg() and qs_fill_sg() fail for legal commands. This patch fixes the assert()'s to take qc->pad_len into account. Although the condition check seems a bit excessive, as this part of code isn't still stable yet, I think it's worth to keep those.

| * [SCSI] fix wrong context bugs in SCSIJames Bottomley2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | There's a bug in releasing scsi_device where the release function actually frees the block queue. However, the block queue release calls flush_work(), which requires process context (the scsi_device structure may release from irq context). Update the release function to invoke via the execute_in_process_context() API. Also clean up the scsi_target structure releasing via this API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [PATCH] add scsi_execute_in_process_context() APIJames Bottomley2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have several points in the SCSI stack (primarily for our device functions) where we need to guarantee process context, but (given the place where the last reference was released) we cannot guarantee this. This API gets around the issue by executing the function directly if the caller has process context, but scheduling a workqueue to execute in process context if the caller doesn't have it. Unfortunately, it requires memory allocation in interrupt context, but it's better than what we have previously. The true solution will require a bit of re-engineering, so isn't appropriate for 2.6.16. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | pm->sg.size is set from the Residual Byte Count register. However, the upper byte of the RBC is the opcode of the instruction that was executing, so we need to mask it off. This fixes some spurious rejects of IGNORE WIDE RESIDUE messages.

| * [SCSI] ipr: Fix adapter initialization failureBrian King2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | Since scsi core is always sending scatterlists now, remove some code which was written with the bad assumption that a small transfer would not be sent down in a scatterlist. Without this fix, the ipr driver ends up sending garbage data to the adapter following a reset, causing it to fail the reset and take the adapter offline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received From Mark Salyzyn. In order to support user tools accessing the array components (SMART, Mode Page information, Cache page adjustments, WWN determination, Firmware updates etc), we take advantage of the no_uld_attach flag and deprecate the code that filters Inquiries to block the requests to array components. The quirk prevents the sd layer from attaching to the components. We also took the opportunity to balance the queue depths based on the total adapter queue depth to the array devices to reduce the chances of starvation.
