* [SCSI] scsi: add transport host byte errors (v3)Mike Christie2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if there is a transport problem the iscsi drivers will return outstanding commands (commands being exeucted by the driver/fw/hw) with DID_BUS_BUSY and block the session so no new commands can be queued. Commands that are caught between the failure handling and blocking are failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values. When the recovery_timeout fires, the iscsi drivers then fail IO with DID_NO_CONNECT. For fcp, some drivers will fail some outstanding IO (disk but possibly not tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry and hits the scsi_error.c failfast check, block the rport, and commands caught in the race are failed with DID_IMM_RETRY. Other drivers, may hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk to be called. The following patches attempt to unify what upper layers will see drivers like multipath can make a good guess. This relies on drivers being hooked into their transport class. This first patch just defines two new host byte errors so drivers can return the same value for when a rport/session is blocked and for when the fast_io_fail_tmo fires. The idea is that if the LLD/class detects a problem and is going to block a rport/session, then if the LLD wants or must return the command to scsi-ml, then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue the IO into the same scsi queue it came from, until the fast io fail timer fires and the class decides what to do. When using multipath and the fast_io_fail_tmo fires then the class can fail commands with DID_TRANSPORT_FAILFAST or drivers can use DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or the equivlent in iscsi if we ever implement more advanced recovery methods. A LLD, like lpfc, could continue to return DID_ERROR and then it will hit the normal failfast path, so drivers do not have fully be ported to work better. The point of the patches is that upper layers will not see a failure that could be recovered from while the rport/session is blocked until fast_io_fail_tmo/recovery_timeout fires. V3 Remove some comments. V2 Fixed patch/diff errors and renamed DID_TRANSPORT_BLOCKED to DID_TRANSPORT_DISRUPTED. V1 initial patch.

* [SCSI] fc class: unblock target after calling terminate callback (take 2)Mike Christie2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we block a rport and the driver implements the terminate callback we will fail IO that was running quickly. However IO that was in the scsi_device/block queue sits there until the dev_loss_tmo fires, and this can make it look like IO is lost because new IO will get executed but that IO stuck in the blocked queue sits there for some time longer. With this patch when the fast io fail tmo fires, we will fail the blocked IO and any new IO. This patch also allows all drivers to partially support the fast io fail tmo. If the terminate io callback is not implemented, we will still fail blocked IO and any new IO, so multipath can handle that. This patch also allows the fc and iscsi classes to implement the same behavior. The timers are just unfornately named differently. This patch also fixes the problem where drivers were unblocking the target in their terminate callback, which was needed for rport removal, but for fast io fail timeout it would cause IO to bounce arround the scsi/block layer and the LLD queuecommand. And it for drivers that could have IO stuck but did not have a terminate callback the unblock calls in the class will fix them. v2. - fix up bit setting style to meet JamesS's pref. - Broke out new host byte error changes to make it easier to read. - added JamesS's ack from list. v1 - initial patch Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Acked-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

* [SCSI] Add helper code so transport classes/driver can control queueing (v3)Mike Christie2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SCSI-ml manages the queueing limits for the device and host, but does not do so at the target level. However something something similar can come in userful when a driver is transitioning a transport object to the the blocked state, becuase at that time we do not want to queue io and we do not want the queuecommand to be called again. The patch adds code similar to the exisiting SCSI_ML_*BUSY handlers. You can now return SCSI_MLQUEUE_TARGET_BUSY when we hit a transport level queueing issue like the hw cannot allocate some resource at the iscsi session/connection level, or the target has temporarily closed or shrunk the queueing window, or if we are transitioning to the blocked state. bnx2i, when they rework their firmware according to netdev developers requests, will also need to be able to limit queueing at this level. bnx2i will hook into libiscsi, but will allocate a scsi host per netdevice/hba, so unlike pure software iscsi/iser which is allocating a host per session, it cannot set the scsi_host->can_queue and return SCSI_MLQUEUE_HOST_BUSY to reflect queueing limits on the transport. The iscsi class/driver can also set a scsi_target->can_queue value which reflects the max commands the driver/class can support. For iscsi this reflects the number of commands we can support for each session due to session/connection hw limits, driver limits, and to also reflect the session/targets's queueing window. Changes: v1 - initial patch. v2 - Fix scsi_run_queue handling of multiple blocked targets. Previously we would break from the main loop if a device was added back on the starved list. We now run over the list and check if any target is blocked. v3 - Rediff for scsi-misc.

| * | | [SCSI] fc_transport: Add an API to allow an LLD to create vportsAndrew Vasquez2008-10-03

This patch adds a symmetric call to the API to allow an NPIV-capable LLD to instantiate vports sans user intervention. Additional comments/updates: Re: scsi_fc_transport.txt Add a function prototype for fc_vport_terminate similar to what's done for fc_vport_create Re: fc_vport_create I recommend we pass the channel number in fc_vport_create rather than fixing it at zero. Also, ids->vport_type should be set to FC_PORTTYPE_NPIV prior to calling fc_vport_create. The comment is also meaningless.

Fix this by adding a new state: CREATED_BLOCK which can only transition back to CREATED and disallow the CREATED -> BLOCK transition. Now both the created and blocked states that the mid-layer recognises can include CREATED_BLOCK. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

It is a reimplementation of the patch posted last week by David Somayajulu. http://marc.info/?l=linux-scsi&m=121745486221819&w=2 There are a few things done differently: - Transport support is included - Event delivery is included - The vendor message is now its own unique message type, considered part of the generic "SCSI Transport". - LLDD entry points are now registered rather than included in the scsi_host_template. Background: When I started to implement the event handler via template, I had to either: muck up scsi_add_host and scsi_remove_host; or have the event handler search all possible shosts. Neither was acceptable. Moving to a registration solves this, and also limits the scope of the changes to something that could be backported to a distro without breaking an already-released-distro kabi. However, I admit it isn't as elegant, as the passing of the LLDD host template in the registration and the complexity around dynamic add/remove shows. - The receive path was augmented to require a unique identifier for the LLDD before the message was allowed to be handed off to the driver. Given how quickly very fatal errors occur if there's msg mismatches (which I saw in testing my own tools :), I believe this to be a very good thing. The id plays off the vendor id scheme already introduced for the vendor unique event messages used by FC. Additionally, the id use as the basis of the registration/deregistration. - Send assist functions, for both the transport and LLDDs are included.
