| * [SCSI] libiscsi: use bh locking instead of irq with session lockMike Christie2010-12-311-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The session lock is taken in threads, timers, and bottom halves like softirqs and tasklets. All the code but iscsi_conn/session_failure take the session lock with the spin_lock_bh call. This was done because I thought some offload drivers would be calling these functions from a irq. They never did, so this patch has iscsi_conn/session_failure use the bh locking. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

| * [SCSI] qla2xxx: Don't perform a BIG_HAMMER if Get-ID (0x20) mailbox command ↵Andrew Vasquez2010-12-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fails on CNAs. The semantics we employ now in the driver, performing a BIG_HAMMER in the event of Get-ID (0x20) mailbox command failing, should only be done for FC. On FC configurations, it makes sense since advertising is only really performed once, so a BIG_HAMMER to reinitiate the process is needed to restart. Under FCoE, this is not needed, as there's a continous stream of advertisements/ACks at the protocol layer to initiate a relogin/reinitialization process.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FCP priority info was not being updated properly in certain situations. Here are the changes that needs to be done to take care of this issue: 1. No need to check fcport->state for FCS_UNCONFIGURED in qla24xx_update_fcport_fcp_prio(), since an invalid loop id check is already performed which is sufficient. 2. Add the missing qla24xx_update_fcport_fcp_prio() function call within qla2x00_update_fcport() function, so that the priority info is updated on every port addition or change. 3. Perform proper adapter types checking. 4. Other changes, associated with DEBUG/printk's and parameter passing.

| * [SCSI] fix medium error problems with some arrays which can cause data ↵James Bottomley2010-12-231-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | corruption Our current handling of medium error assumes that data is returned up to the bad sector. This assumption holds good for all disk devices, all DIF arrays and most ordinary arrays. However, an LSI array engine was recently discovered which reports a medium error without returning any data. This means that when we report good data up to the medium error, we've reported junk originally in the buffer as good. Worse, if the read consists of requested data plus a readahead, and the error occurs in readahead, we'll just strip off the readahead and report junk up to userspace as good data with no error. The fix for this is to have the error position computation take into account the amount of data returned by the driver using the scsi residual data. Unfortunately, not every driver fills in this data, but for those who don't, it's set to zero, which means we'll think a full set of data was transferred and the behaviour will be identical to the prior behaviour of the code (believe the buffer up to the error sector). All modern drivers seem to set the residual, so that should fix up the LSI failure/corruption case.

When a SCSI device attached to a device handler is deleted, userland processes currently performing I/O on the device will have their I/O hang forever. - Set SCSI_DH_NOSYS error when the handler is in the process of being deleted (e.g. the SCSI device is in a SDEV_CANCEL or SDEV_DEL state). - Set SCSI_DH_DEV_OFFLINED error when device is in SDEV_OFFLINE state. - Call the activate_complete callback function directly from scsi_dh_activate if an error has been set (when either the scsi_dh internal data has already been deleted or is in the process of being deleted). The patch was tested in an iSCSI environment, RDAC H/W handler and multipath. In the following reproduction process, dd will I/O hang forever and the only way to release it will be to reboot the machine: 1) Perform I/O on a multipath device: dd if=/dev/dm-0 of=/dev/zero bs=8k count=1000000 & 2) Delete all slave SCSI devices contained in the mpath device: I) In an iSCSI environment, the easiest way to do this is by stopping iSCSI: /etc/init.d/iscsi stop II) Another way to delete the devices is by applying the following bash scriptlet: dm_devs=$(ls /sys/block/ | grep dm- | xargs) for dm_dev in $dm_devs; do devices=$(ls /sys/block/$dm_dev/slaves) for device in $devices; do echo 1 > /sys/block/$device/device/delete done done NOTE: when DM mpath's fail_path uses blk_abort_queue this scsi_dh change isn't strictly required. However, DM mpath's call to blk_abort_queue will soon be reverted because it has proven to be unsafe due to a race (between blk_abort_queue and scsi_request_fn) that can lead to list corruption. Therefore we cannot rely on blk_abort_queue via fail_path, but even if we could this scsi_dh change is still preferrable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement new SLI4 init procedures based on if_type: - Add structure changes for new SLIPORT registers and BAR changes. - Update register names to be consistent with inteface spec terms. - Added union to encapsulate Hardward error registers. - Rework lpfc_sli4_post_status_check() around SLI-4's SLI_INTF type - Removed the lpfc_sli4_fw_cfg_check routine - Segmented driver logic to include evaluation of the if_type to engage different behaviors.

| * [SCSI] lpfc 8.3.20: Implement the FC and SLI async event handlersJames Smart2010-12-215-71/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the FC and SLI async event handlers: - Updated MQ_CREATE_EXT mailbox structure to include fc and SLI async events. - Added the SLI trailer code. - Split physical field into type and number to reflect latest SLI spec. - Changed lpfc_acqe_fcoe to lpfc_acqe_fip to reflect latest Spec changes. - Added lpfc_acqe_fc_la structure for FC link attention async events. - Added lpfc_acqe_sli structure for sli async events. - Added lpfc_sli4_async_fc_evt routine to handle fc la async events. - Added lpfc_sli4_async_sli routine to handle sli async events. - Moved LPFC_TRAILER_CODE_FC to be handled by its own handler function.

| * [SCSI] bfa: io tag handling and minor bug fix.Krishna Gudipati2010-12-214-16/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix iotag handling: 1) Update and check io tag for retry case. 2) Clearing upper 3 bits in io tag when an IO completes. The 3 upper bits in io tags are used for counting FCP exchange retry. Un-cleared bits will cause firmware to access invalid memory when the same io tag is used for an IO to a target that doesn't support FCP exchange retry. 3) Only check the effective bits when validating an iotag. Other minor fixes: 1) Added trace to get FC header type with assert of unhandled packet received. Ignore the type FC_TYPE_FC_FSS (FC_XS). 2) Fixed the adapter info display check - to check for fcmode flag even.

| | | | | | | | | | | | | | | | - Direct attach is not working due to the check of PID in fcxp_send request. - Added logic to set the lps->lp_pid with the PID assigned for n2n mode. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
| * [SCSI] bfa: IOC auto recovery fix.Krishna Gudipati2010-12-216-100/+445
| | | | | | | | | | | | | | | | | | | | - Made IOC auto_recovery synchronized and not timer based. - Only one PCI function will attempt to recover and reinitialize the ASIC on a failure, after all the active PCI fns acknowledge the IOC failure.
