| * [SCSI] qla4xxx: export address/port of connection (fix udev disk names)Mike Christie2011-10-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Udev uses the connection's persistent address/port in the /dev/disk/by-path name. qla4xxx is not exporting this value so its iscsi disk names have been lacking the iscsi info. In the old driver we did not have this information but we do now and can fix this by just setting the flags to tell libiscsi/scsi_transport_iscsi to export this info in sysfs.

| * [SCSI] ipr: Fix BUG on adapter dump timeoutBrian King2011-10-202-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an adapter dump times out, the ipr driver will abort the dump and proceed to reset and recover the adapter. When an adapter dump completes, the work thread which is reading the adapter dump will initiate an adapter reset to recover the adapter. However, when the adapter dump gets aborted, the work thread should not initiate an adapter reset, since an adapter reset is already in progress. This fixes a case of calling pci_block_user_cfg_access overlapped, which results in a BUG.

| * [SCSI] megaraid_sas: Fix instance access in megasas_reset_timeradam radford2011-10-201-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch for megaraid_sas will fix a potential bad pointer access in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be a struct megasas_cmd *, then trying to access cmd->instance, which is invalid. Just loading instance from scmd->device->host->hostdata in megasas_reset_timer() fixes the issue.

| * [SCSI] iscsi class: fix vlan configurationMike Christie2011-10-203-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Userspace was sending the priority/id part of the vlan tag and sysfs was displaying the id in the vlan file. This renames the vlan sysfs file to vlan_id to reflect that it was showing the id and to match the vlan_priority file. This also adds a ISCSI_NET_PARAM_VLAN_TAG iscsi nl command to relfect that we are sending down the vlan/priority part of the tag.

| * [SCSI] aacraid: use lower snprintf() limitDan Carpenter2011-10-201-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is just a cleanup, to silence static checker warnings. It doesn't change how the code works. buf[] can either be BUF_SIZE if this is called from sysfs, or it can be 16 if it's called from aac_get_adapter_info() via aac_get_serial_number(). We use the smaller limit here. sizeof(dev->supplement_adapter_info.MfgPcbaSerialNo) is 12 so there is actually no chance of hitting either limit.

If be2net was loaded before be2iscsi then this leaves be2net driver hanging on to resources that the chip stopped recognising after the reset. This patch replaces chip reset with Function reset so that only the particular function and not the whole chip is affected Signed-off-by: Jayamohan Kallickal <jayamohan.kallickal@emulex.com> Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
| * [SCSI] qlogicpti: fix timeoutMeelis Roos2011-10-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | qlogicpti times out for some tape library operations (like mtx inventory). It seems SCSI command timeout is hardcoded into the driver. Fix it by propagating the timeout from scsi request to the controller as suggested by James Bottomley. Tested on Sun Ultra 1 with Sun StorEdge L8 Autoloader.

| * [SCSI] scsi_dh_alua: Add one more check-condition for alua handlerMoger, Babu2011-10-161-7/+8
| | | | | | | | | | | | | | | | | | | | This patch adds one more check-condition for scsi_dh_alua handler. Without this, the handler attach fails sometimes during the discovery. I have noticed this with NetApp E-Series storage with alua mode. Also removed some unnecessary brackets {} for consistency.

| * [SCSI] ipr: Add support to flash FPGA and flash back DRAM imagesWayne Boyer2011-10-162-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The write buffer command is used to download and burn new IOA FW images. The same interface can now be used to flash FPGA and flash back DRAM images. To download and flash the new images takes more than 15 minutes, so increase the write buffer command timeout to 30 minutes. The FPGA and flash back DRAM images don't have the same card_type as the IOA FW image. So, remove the sanity checking from the driver. The adapter has sanity checking and will only accept a valid image.

| * [SCSI] libsas: fix port->dev_list lockingDan Williams2011-10-163-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | port->dev_list maintains a list of devices attached to a given sas root port. It needs to be mutated under a lock as contexts outside of the single-threaded-libsas-workqueue access the list via sas_find_dev_by_rphy(). Fixup locations where the list was being mutated without a lock. This is a follow-up to commit 5911e963 "[SCSI] libsas: remove expander from dev list on error", where Luben noted [1]: > 2/ We have unlocked list manipulations in sas_ex_discover_end_dev(), > sas_unregister_common_dev(), and sas_ex_discover_end_dev() Yes, I can see that and that is very unfortunate.
