* [SCSI] don't use __GFP_DMA for sense buffers if not requiredJames Bottomley2008-01-233-71/+51
| | | | | | | | | | Only hosts which actually have ISA DMA requirements need sense buffers coming out of ZONE_DMA, so only use the __GFP_DMA flag for that case to avoid allocating this scarce resource if it's not necessary.

* [SCSI] use dynamically allocated sense bufferFUJITA Tomonori2008-01-234-4/+70
| | | | | | | | | | | | | | | | | | | | | This removes static array sense_buffer in scsi_cmnd and uses dynamically allocated sense_buffer (with GFP_DMA). The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves these issues. __scsi_get_command allocates sense_buffer via kmem_cache_alloc and attaches it to a scsi_cmnd so everything just work as before.

* [SCSI] sd: add fix for devices with last sector access problemsHans de Goede2008-01-232-0/+10
| | | | | | | | | | | | This patch adds a new scsi_device flag (last_sector_bug) for devices which contain a bug where the device crashes when the last sector is read in a larger then 1 sector read. This is for example the case with sdcards in the HP PSC1350 printer cardreader and in the HP PSC1610 printer cardreader.

* [SCSI] fix pcmcia compile problemJames Bottomley2008-01-231-1/+2
| | | | | | | | | | | | | | | | | | | This patch commit 8ae732a91df051aba6820068a47b631a06599d84 Author: Tejun Heo <htejun@gmail.com> Date: Fri Dec 7 22:36:23 2007 +0900 [SCSI] make pcmcia directory use obj-y|m instead of subdir-y|m Moved the scsi Makefile into conformance, but also caused the pcmcia subdirectory to get built in for the first time, leading to duplicate symbols in an allyesconfig build. Since evidently no-one relies on these being built in, fix this by ensuring they can only be built as modules.

* [SCSI] aacraid: add Voodoo Lite class of cards.Salyzyn, Mark2008-01-235-6/+48
| | | | | | | | | | | | | | | | | | | The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

* [SCSI] aacraid: add new driver features flagsSalyzyn, Mark2008-01-231-0/+25
| | | | | | | | | | | | | | | | | | | Feature enhancement, adding a 'flags' entry that will reside in the host controller's tree, with a newline separated list of arbitrary ascii named features that indicate whether the combination of driver and controller has support for said feature. Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted.

* [SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support.Andrew Vasquez2008-01-2310-14/+405
| | | | | | | | | | | | | | | | | | | | | FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

* [SCSI] aacraid: fix security weaknessAlan Cox2008-01-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them.

| | | | | | | | | | | | | | | | | | Due to an internal limit associated with the AdapterTypeText field, SMC required a product ID that overloaded the combined vendor and product ID. A decision was made to ship the SMC products without a vendor string dropping the defacto space that used to delineate vendor and product to boot. To correct this, we needed to adjust the code in the driver to parse out the vendor and product strings for the adapter. We match of 'AOC' in the AdapterTypeText, if so we set the vendor to SMC and place the entire AdapterTypeText into the product field. This only affects the cosmetic presentation of the Adapter vendor and product in the logs and in sysfs.

* [SCSI] aacraid: improve queue balancingSalyzyn, Mark2008-01-231-10/+13
| | | | | | | | | | | | | | | | | | | | The adapter queue is divided up equally to all the arrays to prevent command starvation to any individual array. On the other hand, physical targets are only granted a queue depth of one each. The code prior to this patch used to deal with the incremental discovery of targets, but the driver knows how many arrays are present prior to the scan so this knowledge is used to generate a better estimate for the queue depth. Remove the capability of 'physical=0' from preventing access to the class of adapters that have the RAID/SCSI mode of operation since none of the physicals on the SCSI channel are candidates ever for an array. As always, the user can override this default queue depth policy by making the appropriate adjustments utilizing sysfs.
