2011-02-12[SCSI] libfc: add hook to notify providers of local port changesJoe Eykholt4-1/+58
When an SCST provider is registered, it needs to know what local ports are available for configuration as targets. Add a notifier chain that is invoked when any local port that is added or deleted. Maintain a global list of local ports and add an interator function that calls a given function for every existing local port. This is used when first loading a provider.

2011-02-12[SCSI] libfc: add local port hook for provider session lookupJoe Eykholt1-0/+2
The target provider needs a per-instance lookup table or other way to lookup sessions quickly without going through a linear list or serializing too much. Add a simple void * array indexed by FC-4 type to the fc_lport. Signed-off-by: Joe Eykholt <[email protected]> Committed-by: Nicholas A.

2011-02-12[SCSI] libfc: add method for setting handler for incoming exchangeJoe Eykholt2-0/+29
Add a method for setting handler for incoming exchange. For multi-sequence exchanges, this allows the target driver to add a response handler for handling subsequent sequences, and exchange manager resets. The new function is called fc_seq_set_resp().

2011-02-12[SCSI] libfc: add hook for FC-4 provider registrationJoe Eykholt5-36/+259
Allow FC-4 provider modules to hook into libfc, mostly for targets. This should allow any FC-4 module to handle PRLI requests and maintain process-association states. Each provider registers its ops with libfc and then will be called for any incoming PRLI for that FC-4 type on any instance. The provider can decide whether to handle that particular instance using any method it likes, such as ACLs or other configuration information. A count is kept of the number of successful PRLIs from the remote port. Providers are called back with an implicit PRLO when the remote port is about to be deleted or has been reset. fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers, and there is a built-in provider always registered for handling incoming ELS requests. The call to provider recv() routines uses rcu_read_lock() so that providers aren't removed during the call. That lock is very cheap and shouldn't affect any performance on ELS requests. Providers can rely on the RCU lock to protect a session lookup as well.

2011-02-12[SCSI] fcoe: drop FCoE LOGO in FIP modeVasu Dev1-30/+54
Allowing FCoE LOGO followed by CVL in this case prevents FIP login back to the FCF and then keeps lport offline, only FIP LOGO and CLV needs to be processed while in FIP mode, therefore this patch drops FCoE LOGO in FIP mode. Added fcoe_filter_frames() to filter out above mentioned LOGO in fcoe rx path along with other existing filtering in code for bad CRC frames. Adding separate fcoe_filter_frames function helped with better code indentations and if needed then same will allow adding more filters at one place in future. This LOGO drop is added after FCP frames passed up to avoid any additional checks on fast path for this.

2011-02-12[SCSI] fcoe: Fix module reference count for vportsRobert Love1-13/+20
vports are not grabbing module references but are releasing them. This causes the module reference count to decrement too many times and it wraps around past 0. The solution is to do a module_put() in fcoe_interface_release() so that the reference is only released when the fcoe_interface is released. There is a one-to-one relationship between the N_Port and the fcoe_interface, so the module reference will only be dropped when the N_Port is destroyed To create symetry in the code this patch moves the try_module_get() call into fcoe_interface_create(). This means that only the N_Port will grab a reference to the module when its corresponding fcoe_interface is created. This patch also makes it so that the fcoe_interface_create() routine encodes any error codes in the fcoe_interface pointer returned. This way its caller, fcoe_create(), can return an accurate error code.

2011-02-12[SCSI] libfc: always initialize the FCoE DDP exchange id for fsp as ↵Yi Zou1-3/+1
FC_XID_UNKNOWN The fsp's xfer_ddp is used as indication of the exchange id for the DDPed I/O. We should always initialize it as FC_XID_UNKNOWN for a newly allocated fsp, otherwise the fsp allocated in fc_fcp, i.e., not from queuecommand like LUN RESET that is not doing DDP may still think DDP is setup for it since xid 0 is valid and goes on to call fc_fcp_ddp_done() in fc_fcp_resp() from fc_tm_done(). So, set xfer_ddp as FC_XID_UNKNOWN in fc_fcp_pkt_alloc() now. Also removes the setting of fsp->lp as it's already done when fsp is allocated.

Instead of just passing 'EIO' for any I/O error we should be notifying the upper layers with more details about the cause of this error. Update the possible I/O errors to: - ENOLINK: Link failure between host and target - EIO: Retryable I/O error - EREMOTEIO: Non-retryable I/O error - EBADE: I/O error restricted to the I_T_L nexus 'Retryable' in this context means that an I/O error _might_ be restricted to the I_T_L nexus (vulgo: path), so retrying on another nexus / path might succeed. 'Non-retryable' in general refers to a target failure, so this error will always be generated regardless of the I_T_L nexus it was send on. I/O errors restricted to the I_T_L nexus might be retried on another nexus / path, but they should _not_ be queued if no paths are available.

2011-02-12[SCSI] pm8001: simplify workqueue usageTejun Heo3-33/+41
pm8001 manages its own list of pending works and cancel them on device free. It is unnecessarily complex and has a race condition - the works are canceled but not synced, so the work could still be running during and after the data structures are freed. This patch simplifies workqueue usage. * A driver specific workqueue pm8001_wq is created to serve these work items. * To avoid confusion, the "queue" suffixes are dropped from work items and functions. * Delayed queueing was never used. pm8001_work now uses work_struct instead. * The driver no longer keeps track of pending works. All pm8001_works are queued to pm8001_wq and the workqueue is flushed as necessary. flush_scheduled_work() usage is removed during conversion.

and use the doorbell reset method if available (which doesn't lock up the controller if you properly save and restore all the PCI registers that you're supposed to.) Signed-off-by: Stephen M. Cameron <[email protected]> Signed-off-by: James Bottomley <[email protected]>
2011-01-24[SCSI] hpsa: fix board status waiting codeStephen M. Cameron2-8/+40
After a reset, we should first wait for the board to become "not ready", and then wait for it to become "ready", instead of immediately waiting for it to become "ready", and do this waiting *after* restoring PCI config space registers. Also, only wait 10 secs for board to become "not ready" after a reset (it should quickly become not ready.) Signed-off-by: Stephen M.

2011-01-24[SCSI] scsi_dh_alua: add scalable ONTAP lun to dev listMike Snitzer1-0/+1
Currently NetApp's VID/PID details in the INQUIRY response shows up as 'NETAPP' and 'LUN'. With upcoming scalable SAN ONTAP version on NetApp controllers, the PID entry alone is being modified to 'LUN C-Mode' (to distinguish current ONTAP LUNs from scalable ONTAP LUNs). 'LUN' would still suffice for matching 'LUN C-Mode' but best to explicitly add these new NetApp LUNs to the device list.

Initialize stpg_endio() 'err' to SCSI_DH_OK and only change it to SCSI_DH_IO accordingly. This allows the switching of target group state to be properly reported when no error has occurred.
