2013-04-11[SCSI] scsi_dh_alua: Add module parameter to allow failover to non preferred ↵Stewart, Sean1-0/+7
path without STPG Resending with requested rewording of the parameter description. Currently ALUA device handler sends STPG command during failover and failback. Failover can be optimized by implicit failover (by not to sending STPG command), when 1 is passed as hwhandler parameter in multipath.conf. ex "2 alua 1". We may need to pass the parameter through module param for alua device handler to optimize failover if incase retain_attached_hwhandler set in multipath.conf and hwhandler is set with non-tpgs device handler ex: '1 rdac'.

It is not later set to req->sense_len like in the synchrounous exection paths, so we must check the req->sense_len field.

2013-04-06[SCSI] libsas: fix handling vacant phy in sas_set_ex_phy()Lukasz Dorau1-0/+12
If a result of the SMP discover function is PHY VACANT, the content of discover response structure (dr) is not valid. It sometimes happens that dr->attached_sas_addr can contain even SAS address of other phy. In such case an invalid phy is created, what causes NULL pointer dereference during destruction of expander's phys. So if a result of SMP function is PHY VACANT, the content of discover response structure (dr) must not be copied to phy structure. This patch fixes the following bug: BUG: unable to handle kernel NULL pointer dereference at 0000000000000030 IP: [<ffffffff811c9002>] sysfs_find_dirent+0x12/0x90 Call Trace: [<ffffffff811c95f5>] sysfs_get_dirent+0x35/0x80 [<ffffffff811cb55e>] sysfs_unmerge_group+0x1e/0xb0 [<ffffffff813329f4>] dpm_sysfs_remove+0x24/0x90 [<ffffffff8132b0f4>] device_del+0x44/0x1d0 [<ffffffffa016fc59>] sas_rphy_delete+0x9/0x20 [scsi_transport_sas] [<ffffffffa01a16f6>] sas_destruct_devices+0xe6/0x110 [libsas] [<ffffffff8107ac7c>] process_one_work+0x16c/0x350 [<ffffffff8107d84a>] worker_thread+0x17a/0x410 [<ffffffff81081b76>] kthread+0x96/0xa0 [<ffffffff81464944>] kernel_thread_helper+0x4/0x10 Signed-off-by: Lukasz Dorau <lukasz.dorau@intel.com> Signed-off-by: Pawel Baldysiak <pawel.baldysiak@intel.com> Reviewed-by: Maciej Patelczyk <maciej.patelczyk@intel.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2013-04-06[SCSI] st: Take additional queue ref in st_probeJoe Lawrence1-1/+7
This patch fixes a reference count bug in the SCSI tape driver which can be reproduced with the following: * Boot with slub_debug=FZPU, tape drive attached * echo 1 > /sys/devices/... tape device pci path .../remove * Wait for device removal * echo 1 > /sys/kernel/slab/blkdev_queue/validate * Slub debug complains about corrupted poison pattern In commit 523e1d39 (block: make gendisk hold a reference to its queue) add_disk() and disk_release() were modified to get/put an additional reference on a disk queue to fix a reference counting discrepency between bdev release and SCSI device removal. The ST driver never calls add_disk(), so this commit introduced an extra kref put when the ST driver frees its struct gendisk. Attempts were made to fix this bug at the block level [1] but later abandoned due to floppy driver issues [2].
