Some drivers want to be able to just pass in the driver data pointers to the iscsi objects. To enable this we need the iscsi printk macro to cast the object. Signed-off-by:

This removes the session and conn data_size fields from the iscsi_transport. Just pass in the value like with host allocation. This patch also makes it so the LLD iscsi_conn data is allocated with the iscsi_cls_conn. Signed-off-by:

This finishes the host/session unbinding, by adding some helpers to add and remove hosts and the session they manage. Signed-off-by:

bnx2i allocates a host per netdevice but will use libiscsi, so this unbinds the session from the host in that code. This will also be useful for the iser parent device dma settings fixes. Signed-off-by:
-
Mike Christie authored
This renames the iscsi_host to iscsi_cls_host to match the other structs, because libiscsi wants to use the iscsi_host name in the future. Signed-off-by:

max_cmd_len and max_conn are not really used. max_cmd_len is always 16 and can be set by the LLD. max_conn is always one since we do not support MCS. Signed-off-by:

iscsi offload (bnx2i and qla4xx) allocate a scsi host per hba, so the session creation path needs a shost/host_no argument. Software iscsi/iser will follow the same behabior as before where it allcoates a host per session, but in the future iser will probably look more like bnx2i where the host's parent is the hardware (rnic for iser and for bnx2i it is the nic), because it does not use a socket layer like how iscsi_tcp does.

When the firmware is in Fault state it will be identifed only when the next time the driver access the IOC state. This patch includes a polling function in the driver which will be executed in regular interval to check the status of the firmware and if it is in Fault state, then the firmware will be reset by the driver.

drivers/s390/scsi/zfcp_dbf.c:692:2: warning: context imbalance in 'zfcp_rec_dbf_event_thread' - different lock contexts for basic block Replace the parameter indicating if the lock is held with a new entry function that only acquires the lock. This makes the lock handling more visible and removes the sparse warning. Signed-off-by:

There is no need to pack data structures which describe the contents of records in the new recovery trace. lcrash currently depends on the binary format for the other traces, removing the packed attribute from all traces would break trace debugging with lcrash. Signed-off-by:

This change better spreads trace levels of recovery related events. There was an overlap of traces for some recovery triggers and the processing of recovery actions. Signed-off-by:

sbal_last is more appropriate, because it matches sbal_first. Signed-off-by:

Martin Peschke authored
sbal_last is confusing, as it is not the last one actually used, but just a limit. sbal_limit is a better name. Signed-off-by:
-
Martin Peschke authored
This field is not needed, because it designates an index with a fix offset from sbal_first. It's name is confusing anyway. Signed-off-by:

When allocating memory for GID_PN nameserver requests, the allocation function stores the pointer to the mempool, but then overwrites the pointer via memset. Later, the wrong function to free the memory will be called, since this is based on the stored pointer. Fix this by first initializing the struct and then storing the pointer. Signed-off-by:

Processing of an unsolicted status request can lead to a locking race of the request_queue's queue_lock during the recreation of the used up status read request while still in interrupt context of the response handler. Detaching the 'refill' of the long running status read requests from the handler to a scheduled work is solving this issue. In addition, each refill-run is trying to re-establish the full amount of status read requests, which might have failed in earlier runs. Signed-off-by:

USB sometimes doesn't return an error but instead returns a residue value indicating part (or all) of the command wasn't completed. So if the driver _done() error processing indicates the command was fully processed, subtract off the residue so that this USB error gets propagated.

The latency information is provided on a SCSI device level (LUN) which can be found at the following location /sys/class/scsi_device/<H:C:T:L>/device/cmd_latency /sys/class/scsi_device/<H:C:T:L>/device/read_latency /sys/class/scsi_device/<H:C:T:L>/device/write_latency Each sysfs attribute provides the available data: min, max and sum for fabric and channel latency and the number of requests processed. An overrun of the variables is neither detected nor treated. The file has to be read twice to make a meaningful statement, because only the differences of the values between the two reads can be used. A reset of the values can be achieved by writing to the attribute. Signed-off-by:

This patch just removes the dm layer's path initialization completion routine. This is separated from the other patch(scsi_dh: Use SCSI device handler in dm-multipath) Just to make that patch more readable. Signed-off-by:
-
Chandra Seetharaman authored
Before this patch set (SCSI hardware handlers), initialization of a path was done asynchronously. Doing that requires a workqueue in each device/hardware handler module and leads to unneccessary complication in the device handler code, making it difficult to read the code and follow the state diagram. Moving that workqueue to this level makes the device handler code simpler. Hence, the workqueue is moved to dm level. A new workqueue is added instead of adding it to the existing workqueue (kmpathd) for the following reasons: 1. Device activation has to happen faster, stacking them along with the other workqueue might lead to unnecessary delay in the activation of the path. 2. The effect could be felt the other way too. i.e the current events that are handled by the existing workqueue might get a delayed response. Signed-off-by:

This patch converts dm-mpath to use scsi device handlers instead of dm's hardware handlers. This patch does not add any new functionality. Old behaviors remain and userspace tools work as is except that arguments supplied with hardware handler are ignored. One behavioral exception is: Activation of a path is synchronous in this patch, opposed to the older behavior of being asynchronous (changed in patch 07: scsi_dh: Add a single threaded workqueue for initializing a path) Note: There is no need to get a reference for the device handler module (as it was done in the dm hardware handler case) here as the reference is held when the device was first found. Instead we check and make sure that support for the specified device is present at table load time. Signed-off-by:

This patch provides the device handler to support the LSI RDAC SCSI based storage devices. Signed-off-by:
-
Chandra Seetharaman authored
Some of the storage devices (that can be accessed through multiple paths), do need some special handling for 1. Activating the passive path of the storage access. 2. Decode and handle the special sense codes returned by the devices. 3. Handle the I/Os being sent to the passive path, especially during the device probe time. when accessed through multiple paths. As of today this special device handling is done at the dm-multipath layer using dm-handlers. That works well for (1); for (2) to be handled at dm layer, scsi sense information need to be exported from SCSI to dm-layer, which is not very attractive; (3) cannot be done at all at the dm layer. Device handler has been moved to SCSI mainly to handle (2) and (3) properly. Signed-off-by:Mike Anderson <andmike@linux.vnet.ibm.com> Signed-off-by:
