2008-12-16[SCSI] mpt fusion: clear list of outstanding commands on host resetJames Bottomley1-0/+3
A bug in the fusion driver was exposed by the switch to block timeout. Basically, drivers are supposed to terminate commands once error handling begins on them. 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.

2008-10-21[PATCH] beginning of methods conversionAl Viro1-3/+3
To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2008-10-16i2o: Fix 32/64bit DMA lockingAlan Cox7-31/+339
The I2O ioctls assume 32bits. In itself that is fine as they are old cards and nobody uses 64bit. However on LKML it was noted this assumption is also made for allocated memory and is unsafe on 64bit systems. Fixing this is a mess. It turns out there is tons of crap buried in a header file that does racy 32/64bit filtering on the masks. So we: - Verify all callers of the racy code can sleep (i2o_dma_[re]alloc) - Move the code into a new i2o/memory.c file - Remove the gfp_mask argument so nobody can try and misuse the function - Wrap a mutex around the problem area (a single mutex is easy to do and none of this is performance relevant) - Switch the remaining problem kmalloc holdout to use i2o_dma_alloc Cc: Markus Lidel <Markus.Lidel@shadowconnect.com> Cc: Vasily Averin <vvs@sw.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

There's a fault on the FC controllers that makes them not respond correctly to MSI. The SPI controllers are fine, but are likely to be onboard on older motherboards which don't handle MSI correctly, so default both these cases to disabled. Enable by setting the module parameter mpt_msi_enable=1. For the SAS case, enable MSI by default, but it can be disabled by setting the module parameter mpt_msi_enable=0.

2008-05-27[SCSI] fusion mpt: fix target missing after resetting external raidMichael Reed3-12/+0
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.

2008-04-07[SCSI] mptsas: do not use ioc->handle to locate hba portinfo structureMichael Reed2-6/+17
While performing hardware raid reset testing via the raid's client, I noticed that sometimes, following the reset, that there would be more raid targets in the lsscsi output than there actually were raid targets. I tracked this down to the following issue. Fusion cannot always find the mptsas_portinfo structure for the hba because it uses the handle stored in ioc->handle to locate it. The problem is that the firmware can change the handle associated with the hba when h/w raid is reset (via the raid client). When this happens, the driver will allocate another mptsas_portinfo structure and link it into the chain of said structures. This ultimately causes confusion within the driver resulting in targets not being removed when they should be. Eric Moore pointed out that the hba's portinfo structure is always the first structure on the sas_topology list. This patch modifies mptsas.c to access the hba's portinfo structure by taking the first structure on said list.
