scsi: mvsas: fix command_active typo

2017-01-12T10:39:29+00:00

commit af15769ffab13d777e55fdef09d0762bf0c249c4 upstream. gcc-7 notices that the condition in mvs_94xx_command_active looks suspicious: drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active': drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context] This was introduced when the mv_printk() statement got added, and leads to the condition being ignored. This is probably harmless. Changing '&&' to '&' makes the code look reasonable, as we check the command bit before setting and printing it.

scsi: g_NCR5380: Fix release_region in error handling

2017-01-12T10:39:29+00:00

commit 7b93ca43b7e21fbe6fb1a6f4ecce4a2f70f424a0 upstream. When a SW-configurable card is specified but not found, the driver releases wrong region, causing the following message in kernel log: Trying to free nonexistent resource <0000000000000000-000000000000000f> Fix it by assigning base earlier.

sg_write()/bsg_write() is not fit to be called under KERNEL_DS

2017-01-09T07:32:25+00:00

commit 128394eff343fc6d2f32172f03e24829539c5835 upstream. Both damn things interpret userland pointers embedded into the payload; worse, they are actually traversing those. Leaving aside the bad API design, this is very much _not_ safe to call with KERNEL_DS. Bail out early if that happens. Signed-off-by: Al Viro Signed-off-by: Greg Kroah-Hartman

scsi: aacraid: remove wildcard for series 9 controllers

2017-01-09T07:32:22+00:00

commit ae2aae2421983f6f68eb7c4692624bc43ea50712 upstream. Controllers with this PCI ID never shipped outside of PMCS/Microsemi. Remove the ID from the aacraid driver. smartpqi is the correct driver for these controllers.

scsi: avoid a permanent stop of the scsi device's request queue

2017-01-09T07:32:21+00:00

commit d2a145252c52792bc59e4767b486b26c430af4bb upstream. A race between scanning and fc_remote_port_delete() may result in a permanent stop if the device gets blocked before scsi_sysfs_add_sdev() and unblocked after. The reason is that blocking a device sets both the SDEV_BLOCKED state and the QUEUE_FLAG_STOPPED. However, scsi_sysfs_add_sdev() unconditionally sets SDEV_RUNNING which causes the device to be ignored by scsi_target_unblock() and thus never have its QUEUE_FLAG_STOPPED cleared leading to a device which is apparently running but has a stopped queue. We actually have two places where SDEV_RUNNING is set: once in scsi_add_lun() which respects the blocked flag and once in scsi_sysfs_add_sdev() which doesn't. Since the second set is entirely spurious, simply remove it to fix the problem. Reported-by: Zengxi Chen Signed-off-by: Wei Fang Reviewed-by: Ewan D. Milne Signed-off-by: Martin K.

scsi: megaraid_sas: For SRIOV enabled firmware, ensure VF driver waits for 30secs before reset

2017-01-09T07:32:21+00:00

commit 18e1c7f68a5814442abad849abe6eacbf02ffd7c upstream. For SRIOV enabled firmware, if there is a OCR(online controller reset) possibility driver set the convert flag to 1, which is not happening if there are outstanding commands even after 180 seconds. As driver does not set convert flag to 1 and still making the OCR to run, VF(Virtual function) driver is directly writing on to the register instead of waiting for 30 seconds. Setting convert flag to 1 will cause VF driver will wait for 30 secs before going for reset.
