| * | | [SCSI] fcoe: allow SCSI-FCP to be processed directly in softirq contextChris Leech2009-12-04

This preserves the queuing to threads for scaling out receive processing to multiple CPUs, but allows FCoE-aware multi-queue network drivers that direct frames to the originating CPUs to handle FCP processing with less scheduling latency. Only FCP is handled directly, because libfc makes use of mutexes in ELS handling routines. The bulk of this change is just moving the FCoE receive processing out of the receive thread function, leaving behind just the thread and queue management.

Each category is also assigned a Linux return code translation. Analyze the different osd/scsi/block returned errors and set the proper osd_err_priority and Linux return code accordingly. * extra check a few situations so not to get stuck with inconsistent error view. Example an empty residual with an error code, and other places ... Lots of libosd's osd_req_decode_sense clients had this logic in some form or another.

The identification is built from unique target attributes and is the same for all network/SAN machines. osduld_info_lookup() - NEW New API that will lookup an osd_dev by its osd_dev_info. This is used by pNFS-objects for cross network global device identification. And by exofs multy-device support, the device info is specified in the on-disk exofs device table. osduld_device_info() - NEW Given an osd_dev handle returns its associated osd_dev_info. The ULD fetches this information at startup and hangs it on each OSD device. (This is a fast operation that can be called at any condition) osduld_device_same() - NEW With a given osd_dev at one hand and an osd_dev_info at another, we would like to know if they are the same device. Two osd_dev handles can be checked by: osduld_device_same(od1, osduld_device_info(od2)); osd_auto_detect_ver() - REVISED Now returns an osd_dev_info structure. Is only called once by ULD as before.

When doing so the use of an internal kref leaves us a narrow window where a find is started while the actual object can go away. Using the device's kobj reference solves this problem because now the same kref is used for both operations. (Remove and find) Core changes * Embed a struct device in uld_ structure and use device_register instead of devie_create. Set __remove to be the device release function. * __uld_get/put is just get_/put_device. Now every thing is accounted for on the device object. Internal kref is removed. * At __remove() we can safely de-allocate the uld_ structure. (The function has moved to avoid forward declaration) Some cleanups * Use class register/unregister is cleaner for this driver now. * cdev ref-counting games are no longer necessary I have incremented the device version string in case of new bugs.

| * | | [SCSI] libiscsi: hook into ramp up/down handlingMike Christie2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is rare to get a queue full with iscsi, because targets seem to just reduce the iscsi cmd window. However, there is at least one iscsi target that will throw a queue full when overloaded. This hooks the iscsi code in to the ramp up/down code, so we can handle it.

| * | | [SCSI] iscsi class: modify handling of replacement timeoutMike Christie2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the replacement/recovery_timeout so it works more like the fc fast io fail tmo. If userspace tries to set the replacement/recovery_timeout to less than zero, we will turn off the forced recovery cleanup. If userspace sets the value to 0 then we will force the recovery cleanup immediately. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
| * | | [SCSI] libiscsi: add warm target reset tmf supportMike Christie2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements warm target reset tmf support for the scsi-ml target reset callback. Previously we would just drop the session in that callback. This patch will now try a target reset and if that fails drop the session.

| * | | [SCSI] libiscsi: Check TMF state before sending PDUMike Christie2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch and mail from both MikeC and HannesR: Before we're trying to send a PDU we have to check whether a TMF is active. If so and if the PDU will be affected by the TMF we should allow only Data-out PDUs to be sent. If fast_abort is set, no Data-out PDUs will be sent while a LUN reset is being processed for a affected LUN. fast_abort is now ingored during a ABORT TASK tmf. We will not send any Data-outs for a task if the task is being aborted.

| * | | [SCSI] libiscsi: fix login/text checks in pdu injection codeMike Christie2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason we used to check for the the immediate bit set and the opcocde in many places instead of just masking the opcode. In the passthrough code this is a problem because userspace may or may not have set the immediate bit and it does not have to. This fixes up the opcode checks in the passthrough code, so we mask off the opcode then check against the iscsi proto definition like is done in other places.

The suspend works as follows: When ep_poll has succeeed iscsid will call conn_bind, the LLD will then call iscsi_conn_bind which will clear the suspend bit. When ep_disconnect is called (or if there is a conn error) we set the suspend bit. For the ep_disconnect case I added a helper in the previous kernel that will take the session lock to make sure iscsi_queuecommand/xmit_task is not running and it will set the suspend bit.

This is needed if userspace is sending IOs to test the transport like with fcping, so it will not have to wait for the dev loss tmo. With this patch he bsg req fast io fail code behaves like the normal and sg io/passthrough fast io fail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of our virtual SCSI hosts don't have a proper bus parent at the top, which can be a problem for doing DMA on them This patch makes the host device cache a pointer to the physical bus device and provides an extra API for setting it (the normal API picks it up from the parent). This patch also modifies the qla2xxx and lpfc vport logic to use the new DMA host setting API.
