sd: Reject optimal transfer length smaller than page size

2015-12-22T02:37:18Z

Eryu Guan reported that loading scsi_debug would fail. This turned out to be caused by scsi_debug reporting an optimal I/O size of 32KB which is smaller than the 64KB page size on the PowerPC system in question. Add a check to ensure that we only use the device-reported OPTIMAL TRANSFER LENGTH if it is bigger than or equal to the page cache size.

ses: fix additional element traversal bug

2015-12-11T19:05:57Z

KASAN found that our additional element processing scripts drop off the end of the VPD page into unallocated space. The reason is that not every element has additional information but our traversal routines think they do, leading to them expecting far more additional information than is present. Fix this by adding a gate to the traversal routine so that it only processes elements that are expected to have additional information (list is in SES-2 section 6.1.13.1: Additional Element Status diagnostic page overview) Reported-by: Pavel Tikhomirov Tested-by: Pavel Tikhomirov Cc: stable@vger.kernel.org Signed-off-by: James Bottomley

Revert "SCSI: Fix NULL pointer dereference in runtime PM"

2015-12-10T17:24:44Z

This reverts commit 49718f0fb8c9 ("SCSI: Fix NULL pointer dereference in runtime PM") The old commit may lead to a issue that blk_{pre|post}_runtime_suspend and blk_{pre|post}_runtime_resume may not be called in pairs. Take sr device as example, when sr device goes to runtime suspend, blk_{pre|post}_runtime_suspend will be called since sr device defined pm->runtime_suspend. But blk_{pre|post}_runtime_resume will not be called since sr device doesn't have pm->runtime_resume. so, sr device can not resume correctly anymore. More discussion can be found from below link. http://marc.info/?l=linux-scsi&m=144163730531875&w=2 Signed-off-by: Ken Xue Acked-by: Alan Stern Cc: Xiangliang Yu Cc: James E.J.

ses: Fix problems with simple enclosures

2015-12-10T16:14:03Z

Simple enclosure implementations (mostly USB) are allowed to return only page 8 to every diagnostic query. That really confuses our implementation because we assume the return is the page we asked for and end up doing incorrect offsets based on bogus information leading to accesses outside of allocated ranges. Fix that by checking the page code of the return and giving an error if it isn't the one we asked for. This should fix reported bugs with USB storage by simply refusing to attach to enclosures that behave like this. It's also good defensive practise now that we're starting to see more USB enclosures.

mpt3sas: fix Kconfig dependency problem for mpt2sas back compatibility

2015-12-03T17:31:23Z

The non-PCI builds of the O day test project are failing: On Thu, 2015-12-03 at 05:02 +0800, kbuild test robot wrote: > warning: (SCSI_MPT2SAS) selects SCSI_MPT3SAS which has unmet direct > dependencies (SCSI_LOWLEVEL && PCI && SCSI) The problem is that select and depend don't interact because Kconfig doesn't have a SAT solver, so depend picks up dependencies and select does onward selects, but select doesn't pick up dependencies. To fix this, we need to add the correct dependencies to the MPT2SAS option like this. Reported-by: kbuild test robot Fixes: b840c3627b6f4f856b333a14a72f8ed86da2f86c Signed-off-by: James Bottomley

Revert "scsi: Fix a bdi reregistration race"

2015-12-02T19:53:44Z

The SCSI sd driver probes SCSI devices asynchronously. The sd_remove() function, called indirectly by device_del(), waits until asynchronous probing has finished. Since the block layer queue must only be cleaned up after probing has finished, device_del() has to be called before blk_cleanup_queue(). Hence revert commit bf2cf3baa20b.
