2007-08-04[SCSI] aacraid: prevent panic on adapter resource failureSalyzyn, Mark
If the driver fails to allocate the contiguous (DMAable) memory for system reasons, we fail to load the instance, but then we try to free the <nul> allocation in the cleanup code and we get a panic in pci_free_consistent(). This is reported against an older kernel, hope this is relevant for latest/greatest. Signed-off-by: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2007-08-04[SCSI] aha152x: Fix check_condition code-pathBoaz Harrosh
check_condition code-path was similar but more complicated to Reset. It went like this: 1. extra space was allocated at aha152x_scdata for mirroring scsi_cmnd members. 2. At aha152x_internal_queue() every not check_condition (REQUEST_SENSE) command was copied to above members in case of error. 3. At busfree_run() in the DONE_CS phase if a Status of SAM_STAT_CHECK_CONDITION was detected. The command was re-queued Internally using aha152x_internal_queue(,,check_condition,) The old command members are over written with the REQUEST_SENSE info. 4. At busfree_run() in the DONE_CS phase again. If it is a check_condition command, info was restored from mirror made at first call to aha152x_internal_queue() (see 2) and the command is completed. What I did is: 1. Allocate less space in aha152x_scdata only for the 16-byte original command. (which is actually not needed by scsi-ml anymore at this stage. But this is to much knowledge of scsi-ml) 2. If Status == SAM_STAT_CHECK_CONDITION, then like before re-queue a REQUEST_SENSE command. But only now save original command members. (Less of them) 3. In aha152x_internal_queue(), just like for Reset, use the check_condition hint to set differently the working members. execute the command. 4. At busfree_run() in the DONE_CS phase again. restore needed members. While at it. This patch fixes a BUG. Old code when sending a REQUEST_SENSE for a failed command. Would than return with cmd->resid == 0 which was the status of the REQUEST_SENSE. The failing command resid was lost. And when would resid be interesting if not on a failing command?

2007-08-04[SCSI] aha152x: Clean Reset pathBoaz Harrosh
What Reset code was doing: Save command's important/dangerous Info on stack. NULL those members from scsi_cmnd. Issue a Reset. wait for it to finish than restore members and return. What I do is save or NULL nothing. But use the "resetting" hint in aha152x_internal_queue() to NULL out working members and leave struct scsi_cmnd alone. The indent here looks funny but it will change/drop in last patch and it is clear this way what changed. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-08-04[SCSI] aha152x: preliminary fixes and some commentsBoaz Harrosh
hunk by hunk: - CHECK_CONDITION is what happens to cmnd->status >> 1 or after status_byte() macro. But here it is used directly on status which means 0x1 which is an undefined bit in the standard. And is a status that will never return from a target. - in busfree_run at the DONE_SC phase we have 3 distinct operation: 1-if(DONE_SC->SCp.phase & check_condition) The REQUEST_SENSE command return. - Restore original command - Than continue to operation 3. 2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION) A regular command returned with a status. - Internally re-Q a REQUEST_SENSE. - Do not do operation 3. 3- - Complete the command and return it to scsi-ml So the 0x2 in both these operations (1,2) means the scsi check-condition status, hence SAM_STAT_CHECK_CONDITION - Here the code asks about !(DONE_SC->SCp.Status & not_issued) but "not_issued" is an enum belonging to the "phase" member and not to the Status returned from target. The reason this works is because not_issued==1 and Also CHECK_CONDITION==1 (remember from hunk 1). So actually the code was asking !(DONE_SC->SCp.Status & CHECK_CONDITION). Which means "Has the status been read from target yet?" Staus is read at status_run(). "not_issued" is cleared in seldo_run() which is usually earlier than status_run(). So this patch does nothing as far as assembly is concerned but it does let the reader understand what is going on.

2007-08-04[SCSI] sd: disentangle barriers in SCSIJames Bottomley
Our current implementation has a generic set of barrier functions that go through the SCSI driver model. Realistically, this is unnecessary, because the only device that can use barriers (sd) can set the flush functions up at probe or revalidate time. This patch pulls the barrier functions out of the mid layer and scsi driver model and relocates them directly in sd.

2007-07-28[SCSI] aacraid: fix Sunrise Lake reset handlingSalyzyn, Mark
The patch is *much* smaller than the description. I am attempting to answer to those that want to understand an issue that was reported in May this year. If a Sunrise Lake based card that requires an alternate reset mechanism is set up to ignore the commanded IOP_RESET it reports 0x00000010 (IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism to reset all cores), and thus the reset platform function decides to switch to IOP_RESET_ALWAYS because the reset platform function parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS then responds with the 0x3803000F return code, but alas we treat this as an error instead of using the alternate reset mechanism (put a 0x03 into the register offset 0x38). The reset fails, but the fact that the IOP_RESET_ALWAYS command was issued has put the card in a purposeful shutdown state in preparation for the alternate hardware reset to be applied. Yuck. IOP_RESET is ignored in internal production cards, typically to ensure that we catch all adapter lockup issues without the driver progressing further, so this would not appear to be a field issue and thus this patch was destined to be only in the internal Adaptec source tree. IOP_RESET_ALWAYS is reserved for kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as expected in any case. Also in the past we have had OEMs specifically request that cards not be resetable after a BlinkLED/FirmwareAssert for one reason or another and To head off the possibility that the Sunrise Lake based cards would suffer a similar fate, we propose the enclosed fix. Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when he reported an issue to the linux kernel list back in May regarding a kexec problem resulting from this reset being ignore. His fix was to update the Firmware to one that did not ignore the IOP_RESET. Previous kernels did not attempt to reset the adapter and that is why it surfaced as a regression in his hands. The current list of aacraid based cards that use Sunrise Lake: 9005:0285:9005:02b5 Adaptec 5445 9005:0285:9005:02b6 Adaptec 5805 9005:0285:9005:02b7 Adaptec 5085 9005:0285:9005:02c3 Adaptec 51205 9005:0285:9005:02c4 Adaptec 51605 9005:0285:9005:02ce Adaptec 51245 9005:0285:9005:02cf Adaptec 51645 9005:0285:9005:02d0 Adaptec 52445 9005:0285:9005:02d1 Adaptec 5405 9005:0285:9005:02b8 ICP ICP5445SL 9005:0285:9005:02b9 ICP ICP5085SL 9005:0285:9005:02ba ICP ICP5805SL 9005:0285:9005:02c5 ICP ICP5125SL 9005:0285:9005:02c6 ICP ICP5165SL 9005:0285:108e:7aac SUN STK RAID REM 9005:0285:108e:0286 SUN STK RAID INT 9005:0285:108e:0287 SUN STK RAID EXT 9005:0285:108e:7aae SUN STK RAID EM All of these are publicly released with IOP_RESET enabled.

2007-07-28[SCSI] aacraid: add SCSI SYNCHONIZE_CACHE range checkingSalyzyn, Mark
Customer running an application that issues SYNCHRONIZE_CACHE calls directly noticed the broad stroke of the current implementation in the aacraid driver resulting in multiple applications feeding I/O to the storage causing the issuing application to stall for long periods of time. By only waiting for the current WRITE commands, rather than all commands, to complete; and those that are in range of the SYNCHRONIZE_CACHE call that would associate more tightly with the issuing application before telling the Firmware to flush it's dirty cache, we managed to reduce the stalling. The Firmware itself still flushes all the dirty cache associated with the array ignoring the range, it just does so in a more timely manner.

2007-07-27[SCSI] libiscsi: make sure session is not blocked when removing hostMike Christie
When we logout we block the session since we are not taking any more commands, but when we call remove host we want to make sure any IO that got queued up and blocked gets failed upwards quickly, so we unblock the session and fail it.

2007-07-24[SCSI] sym53c8xx: don't claim cpqarray deviceChip Coldwell
Apropos this thread http://marc.theaimsgroup.com/?l=linux-scsi&m=115591706804045&w=2 which led to this patch http://www.kernel.org/git/?p=linux/kernel/git/jejb/scsi-rc-fixes-2.6.git;a=commit;h=b2b3c121076961333977f485f0d54c22121df920 We also need to fix sym53c8xx only to bind to the PCI ID if it is of device class PCI_CLASS_STORAGE_SCSI (otherwise it will be the cpqarray RAID device).

2007-07-24aacraid: fix security holeAlan Cox
On the SCSI layer ioctl path there is no implicit permissions check for ioctls (and indeed other drivers implement unprivileged ioctls). aacraid however allows all sorts of very admin only things to be done so should check.

2007-07-24[SCSI] libsas: SMP request handler shouldn't crash when rphy is NULLDarrick J. Wong
sas_smp_handler crashes when smp utils are used with an aic94xx host because certain devices (the sas_host itself, specifically) lack rphy structures. No rphy means no SMP target support, but we shouldn't crash here. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
