* [SCSI] mptfusion: Fix Incorrect return value in mptscsih_dev_resetKashyap, Desai2011-02-12
| | | | | | | | | | | | | | | | | | | | There's a branch at the end of this function that is supposed to normalize the return value with what the mid-layer expects. In this one case, we get it wrong. Also increase the verbosity of the INFO level printk at the end of mptscsih_abort to include the actual return value and the scmd->serial_number. The reason being success or failure is actually determined by the state of the internal tag list when a TMF is issued, and not the return value of the TMF cmd. The serial_number is also used in this decision, thus it's useful to know for debugging purposes. Cc: stable@kernel.org Reported-by: Peter M.

* [SCSI] mptfusion: Block Error handling for deleting devices or Device in DMDKashyap, Desai2010-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue description: In multipath topology, when device deletion is in transient state, multipath driver can call blk_flush_queue() as part of path failure. Before device get deleted from OS, Device may go OFFLINE as part of error handling kicked off triggered from multipathing driver. Above condition hits more frequently if device missing delay timer (which is LSI specific firmware parameter) is non zero value. root cause of this issue is Error handling thread is getting kicked off for device which is not really present(in transient state of deleting). This patch has solution for this issue. driver is now using eh_timed_out callback. See below. mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out Using mptsas_eh_timed_out function, driver can decide weather vdevice is under Device missing delay or deleting state. for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid and error handling thread will not be kicked off for that particular scsi command.

* [SCSI] mptfusion: schedule_target_reset from all Reset contextKashyap, Desai2010-07-27
| | | | | | | | | | | | | | | | | Issue: target reset will be queued to driver's internal queue to get schedule later. When driver add target into internal target_reset queue we will block IOs on those target using scsi midlayer API. Now due to some cause driver is not executing those target_reset list and it is always in block state. Changes: now we are clearing target_reset queue from all other Callback context instead of only DeviceReset context.Now wherever driver is clearing taskmgmt_in_progress flag it is considering target_reset queue cleanup also.

* [SCSI] mptsas: fix hangs caused by ATA pass-throughRyan Kuester2010-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I may have an explanation for the LSI 1068 HBA hangs provoked by ATA pass-through commands, in particular by smartctl. First, my version of the symptoms. On an LSI SAS1068E B3 HBA running 01.29.00.00 firmware, with SATA disks, and with smartd running, I'm seeing occasional task, bus, and host resets, some of which lead to hard faults of the HBA requiring a reboot. Abusively looping the smartctl command, # while true; do smartctl -a /dev/sdb > /dev/null; done dramatically increases the frequency of these failures to nearly one per minute. A high IO load through the HBA while looping smartctl seems to improve the chance of a full scsi host reset or a non-recoverable hang. I reduced what smartctl was doing down to a simple test case which causes the hang with a single IO when pointed at the sd interface. See the code at the bottom of this e-mail. It uses an SG_IO ioctl to issue a single pass-through ATA identify device command. If the buffer userspace gives for the read data has certain alignments, the task is issued to the HBA but the HBA fails to respond. If run against the sg interface, neither the test code nor smartctl causes a hang. sd and sg handle the SG_IO ioctl slightly differently. Unless you specifically set a flag to do direct IO, sg passes a buffer of its own, which is page-aligned, to the block layer and later copies the result into the userspace buffer regardless of its alignment. sd, on the other hand, always does direct IO unless the userspace buffer fails an alignment test at block/blk-map.c line 57, in which case a page-aligned buffer is created and used for the transfer. The alignment test currently checks for word-alignment, the default setup by scsi_lib.c; therefore, userspace buffers of almost any alignment are given directly to the HBA as DMA targets. The LSI 1068 hardware doesn't seem to like at least a couple of the alignments which cross a page boundary (see the test code below). Curiously, many page-boundary-crossing alignments do work just fine. So, either the hardware has an bug handling certain alignments or the hardware has a stricter alignment requirement than the driver is advertising. If stricter alignment is required, then in no case should misaligned buffers from userspace be allowed through without being bounced or at least causing an error to be returned. It seems the mptsas driver could use blk_queue_dma_alignment() to advertise a stricter alignment requirement. If it does, sd does the right thing and bounces misaligned buffers (see block/blk-map.c line 57). The following patch to 2.6.34-rc5 makes my symptoms go away. I'm sure this is the wrong place for this code, but it gets my idea across. Acked-by: "Desai, Kashyap" <Kashyap.Desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] mptfusion: mpt_detach is called properly at the time of rmmodKashyap, Desai2010-04-11
| | | | | | | | | | | | | | | | | | | Current design of mptsas is as follow. MPTSAS will do probe() if pci id matches for available card in system, irrespective of mode of controller. If controller is I/T mode or I mode, things are fine. If controller is only in T mode, mptsas is not doing complete process of mptsas_probe(). It will only make sure IOC structure is created and IOC reference is available for mptstm driver. Now While removing module we should take care case of Target mode only mptsas. If we are removing IOC which is only in Target mode, We should only detach IOC instead of following rest of the cleanup process which is only required for T mode controller. Now For T mode controller, only part clean up is done instead of complete cleanup. mpt_detach will call early in case of Target mode only controller.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory regionKashyap, Desai2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason for this change is there is a data corruption when four different physical memory regions in the 36GB to 37GB region are accessed. This is only affecting 1078. The solution is we need to use different addressing when filling in the scatter gather table for the effected memory regions. So instead of snooping on all four different memory holes, we treat any physical addresses in the 36GB address with the same algorithm. The fix is explained below 1) Ensure that the message frames are NOT located in the trouble region. There is no remapping available for message frames, they must be allocated outside the problem region. 2) Ensure that Sense buffers are NOT in the trouble region. There is no remapping available. 3) Walk through the SGE entries and if any are inside the trouble region then they need to be remapped as discussed below. 1) Set the Local Address bit in the SGE Flags field. MPI_SGE_FLAGS_LOCAL_ADDRESS 2) Ensure we are using 64-bit SGEs 3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer location is Host Memory.

The fusion apparently wasn't doing this. Under the old timeout regime, completions on terminated commands would by and large get ignored because of the way command timeouts used to work. The new block timers are very intolerant to this, though, becuase the request gets cleaned and freed.

* [SCSI] fusion mpt: fix target missing after resetting external raidMichael Reed2008-05-27
| | | | | | | | | | | | | | | | | | | | | | | | Following a hard reset of a SAS raid, one of the raid targets is occasionally missing. I tracked this down to a pretty obscure little bug. The LSI fusion drivers for SAS and Fibre Channel both use their respective transport layers. Those transport layers increment the target number assigned to new targets. The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host structure to avoid scanning the scsi host adapter. Both fusion drivers set "this_id" from a value returned in a firmware PortFacts response. For my particular test case (SAS) the firmware id assigned to the initiator was 173. After enough raid resets to cause the raid targets to go and come a sufficient number of times, the id assigned by the transport to a raid target would match the id assigned by the host adapter to the "this_id" field, resulting in that target not being scanned. Fix by not assigning this_id and not checking it in slave_configure.

| | | | | | | | | | | | ScsiLookup is an array of pending scmd pointers that the scsi lld maintains. This array is touched from queuecommand, eh threads, and interrupt context. This array should put under locks, hence this patch to synchronize its access. I've added some nice little function wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER struct.
