mptfusion: prevent some memory corruption

2015-11-12T13:09:09+00:00

commit e819cdb198319cccf4af4fc12ac4d796109d8c23 upstream.

These are signed values the come from the user, we put a cap on the
upper bounds but not on the lower bounds.

We use "karg.dataSgeOffset" to calculate "sz".  We verify "sz" and
proceed as if that means that "karg.dataSgeOffset" is correct but this
fails to consider that the "sz" calculations can have integer overflows.

mptfusion: enable no_write_same for vmware scsi disks

2014-10-31T14:11:12+00:00

commit 4089b71cc820a426d601283c92fcd4ffeb5139c2 upstream.

When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used
data can be improperly zeroed out using the mptfusion driver. This patch
disables write_same for this driver and the vmware subsystem_vendor which
ensures that manual zeroing out is used instead.

Pull block core updates from Jens Axboe:

 - Major bit is Kents prep work for immutable bio vecs.

 - Stable candidate fix for a scheduling-while-atomic in the queue
   bypass operation.

 - Fix for the hang on exceeded rq->datalen 32-bit unsigned when merging
   discard bios.

 - Tejuns changes to convert the writeback thread pool to the generic
   workqueue mechanism.

 - Runtime PM framework, SCSI patches exists on top of these in James'
   tree.

 - A few random fixes.

procfs: new helper - PDE_DATA(inode)

2013-04-09T18:13:32+00:00

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

block: Remove some unnecessary bi_vcnt usage

2013-03-23T21:15:31+00:00

More prep work for immutable bvecs/effecient bio splitting - usage of
bi_vcnt has to be auditing, so getting rid of all the unnecessary usage
makes that easier.

Plus, bio_segments() is really what this code wanted, as it respects the
current value of bi_idx.

Drivers: message: remove __dev* attributes.

2013-01-03T23:57:14+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

[SCSI] Fusion MPT: disable pci device when mpt map resoures failed

2012-09-14T16:59:29+00:00

when probe a pci device, first we enable it, and disable it when
some error happened in the following process, because the power
state of the device is set to D0, and if MSI is disabled,
we will allocate irq and register gsi for this device in the enable process.

In function mpt_mapresources(MPT_ADAPTER *ioc), it forgot disable the
pci device when error happened, the irq and gsi will never be released.
this patch will fix it.
