Currently we free the resources backing the enclosure device before we call device_unregister(). This is racy: during rmmod of low-level SCSI drivers that hook into enclosure, we end up with a small window of time during which writing to /sys can OOPS.

The driver core holds a reference over ->remove_dev(), so AFAICT this is safe. Signed-off-by:

In aacraid's ioctl_send_fib() we do two fetches from userspace, one the get the fib header's size and one for the fib itself. Later we use the size field from the second fetch to further process the fib. If for some reason the size from the second fetch is different than from the first fix, we may encounter an out-of- bounds access in aac_fib_send(). We also check the sender size to insure it is not out of bounds. This was reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was assigned CVE-2016-6480. Reported-by:

The lpfc_sli4_scmd_to_wqidx_distr() function expects the scsi_cmnd 'lpfc_cmd->pCmd' not to be null, and point to the midlayer command. That's not true in the .eh_(device|target|bus)_reset_handler path, because lpfc_send_taskmgmt() sends commands not from the midlayer, so does not set 'lpfc_cmd->pCmd'. That is true in the .queuecommand path because lpfc_queuecommand() stores the scsi_cmnd from midlayer in lpfc_cmd->pCmd; and lpfc_cmd is stored by lpfc_scsi_prep_cmnd() in piocbq->context1 -- which is passed to lpfc_sli4_scmd_to_wqidx_distr() as lpfc_cmd parameter. This problem can be hit on SCSI EH, and immediately with sg_reset. These 2 test-cases demonstrate the problem/fix with next-20160601.

When building with -Wextra, we get a lot of warnings for the lpfc driver concerning expressions that are always true, starting with: drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_npiv_init': drivers/scsi/lpfc/lpfc_attr.c:2786:77: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits] drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_rrq_init': drivers/scsi/lpfc/lpfc_attr.c:2802:76: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits] drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_suppress_link_up_init': drivers/scsi/lpfc/lpfc_attr.c:2812:2050: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits] drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_log_verbose_init': drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits] The code works as intended, but it would be nice to shut up the warning so we don't clutter up build logs with this. Using a separate inline function for it makes it clear to the compiler that the comparison is necessary in the caller but still lets it do the constant-folding. [mkp: fix typo] Signed-off-by:

When running in VN2VN mode there is no central instance which would send out any FIP VLAN discovery notifications. So this patch adds a new sysfs attribute 'fip_vlan_responder' which will activate a FIP VLAN discovery responder. Signed-off-by:

The SA controller spins down RAID drive spares. A REGNEWD event causes an inquiry to be sent to all physical drives. This causes the SA controller to spin up the spare. The controller suspends all I/O to a logical volume until the spare is spun up. The spin-up can take over 50 seconds. This can result in one or both of the following: - SML sends down aborts and resets to the logical volume and can cause the logical volume to be off-lined. - a negative impact on the logical volume's I/O performance each time a REGNEWD is triggered.

During hot swap of PCI device, there can be PCI error on device, during normal driver unload. The race between normal driver unload and driver unload due to PCI error, can lead to system crash.Fix is to check if there is unload going on and allow that function to unload the driver. Signed-off-by:
