Administer some love to the osd_req_decode_sense function * Fix a bad bug with osd_req_decode_sense(). If there was no scsi residual, .i.e the request never reached the target, then all the osd_sense_info members where garbage. * Add grossly missing in/out_resid to osd_sense_info and fill them in properly. * Define an osd_err_priority enum which divides the possible errors into 7 categories in ascending severity. 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. Consolidate all these into one place that should actually know about osd returns. Thous translating it to a more abstract error. Signed-off-by:

Define an osd_dev_info structure that Uniquely identifies an OSD device lun on the network. 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. See added comments for how to use. Signed-off-by: -

The true logic of this patch will be clear in the next patch where we use the class_find_device() API. 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. Note: Previous bugfix of taking the reference around fput() still applies. Signed-off-by: -

If scsi has released the device (logout), and exofs has last reference on the osduld_device it will be freed by osd_uld_release() within the call to fput(). But this will oops in cdev_release() which is called after the fops->release. (cdev is embedded within osduld_device). __uld_get/put pair makes sure we have a cdev for the duration of fput() Signed-off-by:

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. Signed-off-by:

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:

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. Signed-off-by:

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. Signed-off-by:

This just has bnx2i use the iscsi_suspend_queue helper. 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.

If the port state is blocked and the fast io fail tmo has fired then this patch will fail bsg requests immediately. 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. Signed-off-by:

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. Acked-By:

The FC-LS spec. says ELS timeouts should be 2 x R_A_TOV. The FC-GS spec. says CT timeouts should be 3 x R_A_TOV. We've been using E_D_TOV for both of those. Change for all ELS and CT requests except FLOGI, which we leave at 2 seconds (using E_D_TOV). One could argue that R_A_TOV is locally determined until after FLOGI succeeds. This does change FLOGI for vports which becomes FDISC. This does not change the REC/SRR timeout which is 2 seconds. Signed-off-by:
