* [SCSI] sym53c8xx: Fix NULL pointer dereference in slave_destroyStratos Psomadakis2012-01-101-0/+4
| | | | | | | | | | sym53c8xx_slave_destroy unconditionally assumes that sym53c8xx_slave_alloc has succesesfully allocated a sym_lcb. This can lead to a NULL pointer dereference (exposed by commit 4e6c82b).

| * SCSI host lock push-downJeff Garzik2010-11-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

| | | | | | | | | | | | | | Make the sym53c8xx_2 driver slave_alloc/destroy less unsafe. References to the destroyed LCB are cleared from the target structure (instead of leaving a dangling pointer), and when the last LCB for the target is destroyed the reference to the upper layer target data is cleared. The host lock is used to prevent a race with the interrupt handler. Also user commands are prevented for targets with all LCBs destroyed.

* [SCSI] sym53c8xx: don't flood syslog with negotiation messagesTony Battersby2009-03-122-3/+29
| | | | | | | | | | | sym53c8xx prints a negotiation message after every check condition. This can add up to a lot of messages for removable-medium devices (CD-ROM, tape drives, etc.) that are being polled, since they return check condition when no medium is present. This patch suppresses the negotiation message if it would be the same as the last one printed.

* [SCSI] sym53c8xx: use a queue depth of 1 for untagged devicesTony Battersby2009-03-121-4/+4
| | | | | | | | | | | | | | | | | | sym53c8xx uses a command queue depth of 2 for untagged devices, without good reason. This _mostly_ seems to work ok, but it has caused me some subtle problems. For example, I have an application where one thread sends write commands to a tape drive, and another thread sends log sense polling commands. With a queue depth of 2, the polling commands end up being starved for long periods of time while multiple write commands are serviced (this may also be related to the fact the the sg driver queues commands in LIFO order). This problem is fixed by changing the queue depth to 1 for untagged devices. I have tested this change extensively with many different tape drives, medium changers, and disk drives (disk drives of course use tagged commands and are therefore unaffected by this patch).

| | | | | | | | | | | | | | | | | | | | sym_init_device() doesn't check if pci_iomap() fails. It also tries to map device RAM without first checking FE_RAM. 1) Move some initialization from sym_init_device() to the top of sym2_probe(). 2) Rename sym_init_device() to sym_iomap_device(). 3) Call sym_iomap_device() after sym_check_supported() instead of before so that device->chip.features will be set. 4) Check FE_RAM in sym_iomap_device() before mapping RAM. 5) If sym_iomap_device() cannot map registers, then abort. 6) If sym_iomap_device() cannot map RAM, then fall back to not using RAM and continue. 7) Remove the check for FE_RAM in sym_attach() since dev->ram_base is now always set correctly.

Also fixed by this patch: During sym2_probe(), if sym_check_raid() returns nonzero, then pci_release_regions() is never called.

* [SCSI] sym53c8xx: Keep transfer negotiations validAaro Koskinen2009-03-122-9/+27
| | | | | | | | | | | | | | | | | | | (The patch updated based on testing and comments from Tony Battersby.) Change the sym53c8xx_2 driver negotiation logic so that the driver will tolerate better device removals. Negotiation message(s) will be sent with every INQUIRY and REQUEST SENSE command, and whenever there is a change in goals or when the device reports check condition. The patch was made specifically to address the case where you hotswap the disk using remove-single-device/add-single-device commands through /proc/scsi/scsi. Without the patch the driver keeps using old transfer parameters even though the target is reset and reports check condition, so the data transfer of the very first INQUIRY will fail.

* block: unify request timeout handlingJens Axboe2008-10-091-2/+2
| | | | | | | | | | | | | Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.

| | | | | | | | | | | | | | | | This function just printed a message to the user; move the print to its only caller, and turn it into an starget_printk. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcbMatthew Wilcox2007-10-236-85/+99
| | | | | | | | | | | | | | | | | | | | | | | | This structure is accessed by the device; the fewer Linux things in it, the better. Using the pci_dev pointer from the hostdata requires a lot of changes: - Pass Scsi_Host to a lot of routines which currently take a sym_hcb. - Set the Scsi_Host as the pci drvdata (instead of the sym_hcb) Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONEMatthew Wilcox2007-10-234-65/+66
| | | | | | | | | | | | | | | | | | | | | | Make sym_interrupt return an irqreturn_t instead of void, and take a Scsi_Host instead of a sym_hcb. Pass the Scsi_Host to the interrupt handler instead of the sym_hcb. Rename the host_data to sym_data. Keep a pci_dev pointer in the sym_data. Rename the Scsi_Host from instance to shost.

| * [SCSI] sym53c8xx: Get rid of IRQ_FMT and IRQ_PRMMatthew Wilcox2007-10-231-8/+5

| * [SCSI] sym53c8xx: Use scmd_printk where appropriateMatthew Wilcox2007-10-232-20/+19
| | | | | | | | | | | | | | | | If we have a scsi_cmnd, it gives the user more information than the sym_name, and maybe the target. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] sym53c8xx: Simplify DAC DMA handlingMatthew Wilcox2007-10-234-42/+26
| | | | | | | | | | | | | | | | | | | | | | By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can eliminate a lot of ifdefs from the code. We now rely on the compiler to optimise away a few things that we'd formerly relied on the preprocessor to do. This makes sym_setup_bus_dma_mask() small enough to inline into its only caller.

| | | | | | | | | | | | | | | | | | With sysfs making these options tunable at runtime, there's no justification for keeping this horrendously complex specification string around. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the PCI error recovery callbacks to the Symbios SCSI device driver. It includes support for First Failure Data Capture. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Assorted changes to initial patches, including returning IRQ_NONE from the interrupt handler if the device is offline and re-using the eh_done completion in the scsi error handler.

| * [SCSI] sym53c8xx: Stop overriding scsi_doneMatthew Wilcox2007-10-231-42/+18
| | | | | | | | | | | | | | | | | | | | Instead of telling the reset routine that the command completed from sym_eh_done, do it from sym_xpt_done. The 'to_do' element of the ucmd is redundant -- it serves only to tell whether eh_done is valid or not, and we can tell this by checking to see if it's NULL.
