2008-10-13[SCSI] modify scsi to handle new fail fast flags.Mike Christie
This checks the errors the scsi-ml determined were retryable and returns if we should fast fail it based on the request fail fast flags. Without the patch, drivers like lpfc, qla2xxx and fcoe would return DID_ERROR for what it determines is a temporary communication problem. There is no loss of connectivity at that time and the driver thinks that it would be fast to retry at the driver level. SCSI-ml will however sees fast fail on the request and DID_ERROR and will fast fail the io. This will then cause dm-multipath to fail the path and possibley switch target controllers when we should be retrying at the scsi layer. We also were fast failing device errors to dm multiapth when unless the scsi_dh modules think otherwis we want to retry at the scsi layer because multipath can only retry the IO like scsi should have done. multipath is a little dumber though because it does not what the error was for and assumes that it should fail the paths.

2008-10-13[SCSI] block: separate failfast into multiple bits.Mike Christie
Multipath is best at handling transport errors. If it gets a device error then there is not much the multipath layer can do. It will just access the same device but from a different path. This patch breaks up failfast into device, transport and driver errors. The multipath layers (md and dm mutlipath) only ask the lower levels to fast fail transport errors. The user of failfast, read ahead, will ask to fast fail on all errors. Note that blk_noretry_request will return true if any failfast bit is set. This allows drivers that do not support the multipath failfast bits to continue to fail on any failfast error like before. Drivers like scsi that are able to fail fast specific errors can check for the specific fail fast type. In the next patch I will convert scsi.

2008-10-13[SCSI] qla2xxx: use new host byte transport errors.Mike Christie
This has qla2xxx use the new transport error values instead of DID_BUS_BUSY. I am not sure if all the errors in qla_isr.c I changed are transport related. We end up blocking/deleting the rport for all of them so it is better to use the new transport error since the fc classs will decide when to fail the IO. With this patch if I pull a cable then IO that had reached the driver, will be failed with DID_TRANSPORT_DISRUPTED (not including tape). The fc class will then fail the IO when the fast io fail tmo has fired, and the driver will flush any other commands running.

2008-10-13[SCSI] scsi: add transport host byte errors (v3)Mike Christie
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.

2008-10-13[SCSI] fc class: unblock target after calling terminate callback (take 2)Mike Christie
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>

2008-10-13[SCSI] Add helper code so transport classes/driver can control queueing (v3)Mike Christie
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.

2008-10-12Fix RTC wakealarm sysfs interface breakage.Linus Torvalds
Commit ed458df4d2470adc02762a87a9ad665d0b1a2bd4 ("PnP: move pnpacpi/pnpbios_init to after PCI init") moved the PnP RTC discovery later, and now the ACPI RTC glue code doesn't find it any more, breaking the RTC wakealarm sysfs interfaces, as reported by Rafael. This really is fairly messy, and we have several annoying ordering constraints here - the PnP code that sets up the RTC resources wants to run after the PCI resources have to be registered, which in turn needs to run after ACPI has at least enumerated the root PCI buses etc. Our initcall ordering is not fine-grained enough to make this all painless. So this moves the ACPI RTC glue ("acpi_rtc_init()") down to a regular module call, which fixes the problem Rafael has. The reason this isn't wonderful is that we really should do acpi_rtc_init before we do the rtc_cmos init, and now those two are in the same module_init() section. Which happens to work, but only because drivers/rtc is linked after drivers/acpi. In other words, we still have a very subtle ordering issue here. Grr. Reported-and-tested-by: Rafael J.
