tracing: Allow creating instances with specified system events A trace instance may only need to enable specific events. As the eventfs directory of an instance currently creates all events which adds overhead, allow internal instances to be created with just the events in systems that they care about. This currently only deals with systems and not individual events, but this should bring down the overhead of creating instances for specific use cases quite bit. The trace_array_get_by_name() now has another parameter "systems". This parameter is a const string pointer of a comma/space separated list of event systems that should be created by the trace_array. (Note if the trace_array already exists, this parameter is ignored). The list of systems is saved and if a module is loaded, its events will not be added unless the system for those events also match the systems string.

Since commit f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

scsi: qla2xxx: Log message "skipping scsi_scan_host()" as informational This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd be nice to log it by default instead of only being enabled with debug. This user had an accidental/forgotten file modprobe.d/qla2xxx.conf w/ option qlini_mode=disabled from experiments with FC target mode, and their boot LUN didn't come up, as it skips SCSI scan, of course. However, their boot log didn't provide any clues to help understand that. The issue/message could be figured out w/ ql2xextended_error_logging, but it would have been simpler (or even deflected/addressed by user) if it had been there by default. And it also would help support/triage/deflection tooling.

scsi: qla2xxx: Fix response queue handler reading stale packets On some platforms, the current logic of relying on finding new packet solely based on signature pattern can lead to driver reading stale packets. Though this is a bug in those platforms, reduce such exposures by limiting reading packets until the IN pointer. Two module parameters are introduced: ql2xrspq_follow_inptr: When set, on newer adapters that has queue pointer shadowing, look for response packets only until response queue in pointer. When reset, response packets are read based on a signature pattern logic (old way). ql2xrspq_follow_inptr_legacy: Like ql2xrspq_follow_inptr, but for those adapters where there is no queue pointer shadowing.

scsi: qla2xxx: Implement ref count for SRB The timeout handler and the done function are racing. When qla2x00_async_iocb_timeout() starts to run it can be preempted by the normal response path (via the firmware?). qla24xx_async_gpsc_sp_done() releases the SRB unconditionally. When scheduling back to qla2x00_async_iocb_timeout() qla24xx_async_abort_cmd() will access an freed sp->qpair pointer: qla2xxx [0000:83:00.0]-2871:0: Async-gpsc timeout - hdl=63d portid=234500 50:06:0e:80:08:77:b6:21. qla2xxx [0000:83:00.0]-2853:0: Async done-gpsc res 0, WWPN 50:06:0e:80:08:77:b6:21 qla2xxx [0000:83:00.0]-2854:0: Async-gpsc OUT WWPN 20:45:00:27:f8:75:33:00 speeds=2c00 speed=0400. qla2xxx [0000:83:00.0]-28d8:0: qla24xx_handle_gpsc_event 50:06:0e:80:08:77:b6:21 DS 7 LS 6 rc 0 login 1|1 rscn 1|0 lid 5 BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: qla24xx_async_abort_cmd+0x1b/0x1c0 [qla2xxx] Obvious solution to this is to introduce a reference counter. One reference is taken for the normal code path (the 'good' case) and one for the timeout path. As we always race between the normal good case and the timeout/abort handler we need to serialize it. Also we cannot assume any order between the handlers. Since this is slow path we can use proper synchronization via locks. When we are able to cancel a timer (del_timer returns 1) we know there can't be any error handling in progress because the timeout handler hasn't expired yet, thus we can safely decrement the refcounter by one. If we are not able to cancel the timer, we know an abort handler is running. We have to make sure we call sp->done() in the abort handlers before calling kref_put().

scsi: qla2xxx: edif: Add doorbell notification for app Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. During runtime, driver and authentication application need to stay in sync in terms of: Session being down|up, arrival of new authentication message (AUTH ELS) and SADB update completion. These events are queued up as doorbell to the authentication application. Application would read this doorbell on regular basis to stay up to date. Each SCSI host would have a separate doorbell queue. The doorbell interface can daisy chain a list of events for each read. Each event contains an event code + hint to help application steer the next course of action.

scsi: qla2xxx: edif: Add detection of secure device Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. There is no FC switch scan service that can indicate whether a device is secure or non-secure. In order to detect whether the remote port supports encrypted operation, driver must first do a PLOGI with the remote device. On completion of the PLOGI, driver will query firmware to see if the device supports secure login. To do that, driver + firmware must advertise the security bit via PLOGI's service parameter. The remote device shall respond using the same service parameter whether it supports it or not.

scsi: qla2xxx: edif: Add key update Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. As part of the authentication process, the authentication application will generate a SADB entry (Security Association/SA, key, SPI value, etc). This SADB is then passed to driver to be programmed into hardware. There will be a pair of SADB's (Tx and Rx) for each connection. After some period, the application can choose to change the key. At that time, a new set of SADB pair is given to driver. The old set of SADB will be deleted. Add a new bsg call (QL_VND_SC_SA_UPDATE) to allow application to allow adding or deleting SADB entries. Driver will not keep the key in memory. It will pass it to HW. It is assumed that application will assign a unique SPI value to this SADB (SA + key). Driver + hardware will assign a handle to track this unique SPI/SADB.

scsi: qla2xxx: Remove in_interrupt() from qla83xx-specific code qla83xx_wait_logic() is used to control the frequency of device IDC lock retries. If in_interrupt() is true, it does 20 loops of cpu_relax(). Otherwise, it sleeps for 100ms and yields the CPU. While in_interrupt() is ill-defined and does not provide what the name suggests, it is not needed here: that qla83xx_wait_logic() is exclusively called by qla83xx_idc_lock() / unlock(), and they always run from process context. Below is an analysis of all the idc lock/unlock callers, in order of appearance: - qla_os.c: qla83xx_nic_core_unrecoverable_work(), qla83xx_idc_state_handler_work(), qla83xx_nic_core_reset_work(), qla83xx_service_idc_aen(), all workqueue context - qla_os.c: qla83xx_check_nic_core_fw_alive(), has msleep() - qla_os.c: qla83xx_set_drv_presence(), called once from qla2x00_abort_isp(), which is bound to process-context ->abort_isp() hook. It also invokes wait_for_completion_timeout() through the chain qla2x00_configure_hba() => qla24xx_link_initialize() => qla2x00_mailbox_command(). - qla_os.c: qla83xx_clear_drv_presence(), which is called from qla2x00_abort_isp() discussed above, and from qla2x00_remove_one() which is PCI process-context ->remove() hook. - qla_os.c: qla83xx_need_reset_handler(), has a one second msleep() in a loop. - qla_os.c: qla83xx_device_bootstrap(), called only by qla83xx_idc_state_handler(), which has multiple msleep() invocations. - qla_os.c: qla83xx_idc_state_handler(), multiple msleep() invocations. - qla_attr.c: qla2x00_sysfs_write_reset(), sysfs bin_attribute ->write() hook, process context - qla_init.c: qla83xx_nic_core_fw_load() => qla_init.c: qla2x00_initialize_adapter() => bound to isp_operations ->initialize_adapter() hook ** => qla_os.c: qla2x00_probe_one(), PCI ->probe() process ctx - qla_init.c: qla83xx_initiating_reset(), msleep() in a loop. - qla_init.c: qla83xx_nic_core_reset(), called by qla83xx_nic_core_reset_work(), workqueue context. Remove the in_interrupt() check, and thus replace the entirety of qla83xx_wait_logic() with an msleep(QLA83XX_WAIT_LOGIC_MS). Mark qla83xx_idc_lock() / unlock() with "Context: task, can sleep".

scsi: qla2xxx: Fix MPI failure AEN (8200) handling Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular firmware dump is also taken and then chip reset. This is disruptive to IOs and not required. Make the firmware dump collection, followed by chip reset, optional (not done by default). Firmware dump buffer and MPI dump buffer are independent of each other with this change and each can have dump that was taken at two different times for two different issues. The MPI dump is saved in a separate buffer and is retrieved differently from firmware dump. To collect full dump on MPI failure AEN, a module parameter is introduced: ql2xfulldump_on_mpifail (default: 0) Link: https://lore.kernel.org/r/20200331104015.24868-2-njavali@marvell.com Reported-by: kbuild test robot <lkp@intel.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Signed-off-by: Arun Easi <aeasi@marvell.com> Signed-off-by: Nilesh Javali <njavali@marvell.com> Signed-off-by: Martin K.

scsi: qla2xxx: check UNLOADING before posting async work qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the completion of these async commands. If UNLOADING is set, this is doomed to timeout, because the async logout command will never complete. The only way to avoid waiting pointlessly is to fail posting these commands in the first place if the driver is in UNLOADING state. In general, posting any command should be avoided when the driver is UNLOADING. With this patch, "rmmod qla2xxx" completes without noticeable delay.

scsi: qla2xxx: set UNLOADING before waiting for session deletion The purpose of the UNLOADING flag is to avoid port login procedures to continue when a controller is in the process of shutting down. It makes sense to set this flag before starting session teardown. Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the test for UNLOADING is postponed until after the check for an already disabled PCI board.

scsi: qla2xxx: Update BPM enablement semantics. commit e4e3a2ce9556 ("scsi: qla2xxx: Add ability to autodetect SFP type") takes a heavy handed approach to BPM (Buffer Plus Management) enablement: 1) During hardware initialization, if an LR-capable transceiver is recognized, the driver schedules a disruptive post-initialization chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the firmware. This chip-reset will result in (short-term) path-loss to all fc-rports and their attached SCSI devices. 2) LR-detection is triggered during any link-up event, resulting in a refresh and potential chip-reset Based on firmware-team guidance, upon LR-capable transceiver recognition, the driver's hardware initialization code will now re-execute firmware with the new BPM settings, then continue on with driver initialization. To address the second issue, the driver performs LR-capable detection upon the driver receiving a transceiver-insertion asynchronous event from firmware. No short-term path loss is needed with this new semantic.

Instead, rely on the firmware to return an error code when attempting to abort a command that has already completed. Additionally, rely on the firmware to return an error code when attempting to abort an already aborted command. In qla2x00_abort_srb(), use blk_mq_request_started() instead of sp->completed and sp->aborted.

scsi: qla2xxx: Fix double scsi_done for abort path Current code assumes abort will remove the original command from the active list where scsi_done will not be called. Instead, the eh_abort thread will do the scsi_done. That is not the case. Instead, we have a double scsi_done calls triggering use after free. Abort will tell FW to release the command from FW possesion. The original command will return to ULP with error in its normal fashion via scsi_done. eh_abort path would wait for the original command completion before returning. eh_abort path will not perform the scsi_done call.

scsi: qla2xxx: Add cleanup for PCI EEH recovery During EEH error recovery testing it was discovered that driver's reset() callback partially frees resources used by driver, leaving some stale memory. After reset() is done and when resume() callback in driver uses old data which results into error leaving adapter disabled due to PCIe error. This patch does cleanup for EEH recovery code path and prevents adapter from getting disabled.

scsi: qla2xxx: Fix race conditions in the code for aborting SCSI commands In the *_done() functions, instead of returning early if sp->ref_count >= 2, only decrement sp->ref_count. In qla2xxx_eh_abort(), instead of deciding what to do based on the value of sp->ref_count, decide which action to take depending on the completion status of the firmware abort. Remove srb.cwaitq and use srb.comp instead. In qla2x00_abort_srb(), call isp_ops->abort_command() directly instead of calling qla2xxx_eh_abort().

scsi: qla2xxx: target: Fix offline port handling and host reset handling Remove the function qlt_abort_cmd_on_host_reset() because it can do the following, all of which can cause a kernel crash: - DMA unmapping while DMA is in progress. - Call target_execute_cmd() while DMA is in progress. - Call transport_generic_free_cmd() while the LIO core owns a command. Instead of trying to abort a command asynchronously, set the 'aborted' flag and handle the abort after the hardware has passed control back to the tcm_qla2xxx driver.

scsi: qla2xxx: Use correct number of vectors for online CPUs When SCSI-MQ is enabled, in some case system would present nr_possible_cpus() which is greater than requested vectors by the driver. This results into driver being able to get larger number of MSI-X vectors than actual online CPUs. Driver then uses pci_alloc_irq_vectors_affinity() to assign 1:1 mapping and affinity for each MSI-x vector to CPUs. When the command is submitted using MSI-x vector, assigned to offline CPU, it results in an ABTS and system hang. This hang is result of a driver not being able to process interrupt on a vector assigned to an Off-line CPUs This patch fixes this issue by setting irq_offset value for the blk_mq_pci_map_queues() to use only those CPUs which has CPU mask affinity assigned and are online. By using the irq_offset value, driver will allow online cpumask to decide which vectors are used in blk_mq_pci_map_queues().

scsi: qla2xxx: Move rport registration out of internal work_list Currently, the rport registration is being called from a single work element that is used to process QLA internal "work_list". This work_list is meant for quick and simple task (ie no sleep). The Rport registration process sometime can be delayed by upper layer. This causes back pressure with the internal queue where other jobs are unable to move forward. This patch will schedule the registration process with a new work element (fc_port.reg_work). While the RPort is being registered, the current state of the fcport will not move forward until the registration is done. If the state of the fabric has changed, a new field/next_disc_state will record the next action on whether to 'DELETE' or 'Reverify the session/ADISC'.

scsi: qla2xxx: Migrate NVME N2N handling into state machine This patch fixes regression introduced for the N2N support for FC-NVMe. For FC-NVMe with N2N connection, instead of FW initiating the Login, Driver starts Login process. This patch migrates that new process from a standalone path into existing session management state machine. With this state change now driver will not wait for pull NPort ID from FW.

treewide: kzalloc() -> kcalloc() The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.

scsi: qla2xxx: Fix small memory leak in qla2x00_probe_one on probe failure The code that fixes the crashes in the following commit introduced a small memory leak: commit 6a2cf8d3663e ("scsi: qla2xxx: Fix crashes in qla2x00_probe_one on probe failure") Fixing this requires a bit of reworking, which I've explained. Also provide some code cleanup. There is a small window in qla2x00_probe_one where if qla2x00_alloc_queues fails, we end up never freeing req and rsp and leak 0xc0 and 0xc8 bytes respectively (the sizes of req and rsp). I originally put in checks to test for this condition which were based on the incorrect assumption that if ha->rsp_q_map and ha->req_q_map were allocated, then rsp and req were allocated as well. This is incorrect. There is a window between these allocations: ret = qla2x00_mem_alloc(ha, req_length, rsp_length, &req, &rsp); goto probe_hw_failed; [if successful, both rsp and req allocated] base_vha = qla2x00_create_host(sht, ha); goto probe_hw_failed; ret = qla2x00_request_irqs(ha, rsp); goto probe_failed; if (qla2x00_alloc_queues(ha, req, rsp)) { goto probe_failed; [if successful, now ha->rsp_q_map and ha->req_q_map allocated] To simplify this, we should just set req and rsp to NULL after we free them. Sounds simple enough? The problem is that req and rsp are pointers defined in the qla2x00_probe_one and they are not always passed by reference to the routines that free them. Here are paths which can free req and rsp: PATH 1: qla2x00_probe_one ret = qla2x00_mem_alloc(ha, req_length, rsp_length, &req, &rsp); [req and rsp are passed by reference, but if this fails, we currently do not NULL out req and rsp. Easily fixed] PATH 2: qla2x00_probe_one failing in qla2x00_request_irqs or qla2x00_alloc_queues probe_failed: qla2x00_free_device(base_vha); qla2x00_free_req_que(ha, req) qla2x00_free_rsp_que(ha, rsp) PATH 3: qla2x00_probe_one: failing in qla2x00_mem_alloc or qla2x00_create_host probe_hw_failed: qla2x00_free_req_que(ha, req) qla2x00_free_rsp_que(ha, rsp) PATH 1: This should currently work, but it doesn't because rsp and rsp are not set to NULL in qla2x00_mem_alloc. Easily remedied. PATH 2: req and rsp aren't passed in at all to qla2x00_free_device but are derived from ha->req_q_map[0] and ha->rsp_q_map[0]. These are only set up if qla2x00_alloc_queues succeeds. In qla2x00_free_queues, we are protected from crashing if these don't exist because req_qid_map and rsp_qid_map are only set on their allocation. We are guarded in this way: for (cnt = 0; cnt < ha->max_req_queues; cnt++) { if (!test_bit(cnt, ha->req_qid_map)) continue; PATH 3: This works. We haven't freed req or rsp yet (or they were never allocated if qla2x00_mem_alloc failed), so we'll attempt to free them here. To summarize, there are a few small changes to make this work correctly and (and for some cleanup): 1) (For PATH 1) Set *rsp and *req to NULL in case of failure in qla2x00_mem_alloc so these are correctly set to NULL back in qla2x00_probe_one 2) After jumping to probe_failed: and calling qla2x00_free_device, explicitly set rsp and req to NULL so further calls with these pointers do not crash, i.e. the free queue calls in the probe_hw_failed section we fall through to. 3) Fix return code check in the call to qla2x00_alloc_queues. We currently drop the return code on the floor. The probe fails but the caller of the probe doesn't have an error code, so it attaches to pci. This can result in a crash on module shutdown. 4) Remove unnecessary NULL checks in qla2x00_free_req_que, qla2x00_free_rsp_que, and the egregious NULL checks before kfrees and vfrees in qla2x00_mem_free. I tested this out running a scenario where the card breaks at various times during initialization. I made sure I forced every error exit path in qla2x00_probe_one.

scsi: qla2xxx: Fix crashes in qla2x00_probe_one on probe failure Because of the shifting around of code in qla2x00_probe_one recently, failures during adapter initialization can lead to problems, i.e. NULL pointer crashes and doubly freed data structures which cause eventual panics. This V2 version makes the relevant memory free routines idempotent, so repeat calls won't cause any harm. I also removed the problematic probe_init_failed exit point as it is not needed.

When driver is not able to get reqeusted IRQs from the system, driver will attempt tp clean up memory before failing hardware probe. During this cleanup, driver assigns NULL value to the pointer which has not been allocated by driver yet. This results in a NULL pointer access.

The routine qla2x00_probe_one() detects the error case and jumps to probe_failed, but has already assigned the return value from kthread_create() to ha->dpc_thread. Then probe_failed checks to see if ha->dpc_thread is not NULL before doing cleanup on it. Since in the error case this is also not NULL, it ends up trying to access an invalid task pointer. Solution is to assign NULL to ha->dpc_thread in the error path to avoid kthread cleanup in that case.

scsi: qla2xxx: Do not call abort handler function during chip reset If there are IO's running and host reset or chip reset is triggered, IO's can fail due to rport time out. During chip reset recovery process, driver notifies the transport layer that remote port no longer exist, by calling fc_remote_port_delete(). When this function is called, it actually delays deletion by "blocking" it. It sets the remote port state to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When driver tries to abort the command by calling its abort handler function, abort handler will wait until remote port state is blocked state or wait for dev_loss_tmo time. Due to this blocking, rport times out and results in an IO failure. This patch adds a check for any active reset process before calling abort handler function.

qla2xxx: Add framework for async fabric discovery Currently code performs a full scan of the fabric for every RSCN. Its an expensive process in a noisy large SAN. This patch optimizes expensive fabric discovery process by scanning switch for the affected port when RSCN is received. Currently Initiator Mode code makes login/logout decision without knowledge of target mode. This causes driver and firmware to go out-of-sync. This framework synchronizes both initiator mode personality and target mode personality in making login/logout decision. This patch adds following capabilities in the driver - Send Notification Acknowledgement asynchronously. - Update session/fcport state asynchronously. - Create a session or fcport struct asynchronously. - Send GNL asynchronously. The command will ask FW to provide a list of FC Port entries FW knows about. - Send GPDB asynchronously. The command will ask FW to provide detail data of an FC Port FW knows about or perform ADISC to verify the state of the session. - Send GPNID asynchronously. The command will ask switch to provide WWPN for provided NPort ID. - Send GPSC asynchronously. The command will ask switch to provide registered port speed for provided WWPN. - Send GIDPN asynchronously. The command will ask the switch to provide Nport ID for provided WWPN. - In driver unload path, schedule all session for deletion and wait for deletion to complete before allowing driver unload to proceed.

scsi: qla2xxx: do not abort all commands in the adapter during EEH recovery The previous commit 1535aa75a3d8 ("qla2xxx: fix invalid DMA access after command aborts in PCI device remove") introduced a regression during an EEH recovery, since the change to the qla2x00_abort_all_cmds() function calls qla2xxx_eh_abort(), which verifies the EEH recovery condition but handles it heavy-handed. (commit a465537ad1a4 "qla2xxx: Disable the adapter and skip error recovery in case of register disconnect.") This problem warrants a more general/optimistic solution right into qla2xxx_eh_abort() (eg in case a real command abort arrives during EEH recovery, or if it takes long enough to trigger command aborts); but it's still worth to add a check to ensure the code added by the previous commit is correct and contained within its owner function. This commit just adds a 'if (!ha->flags.eeh_busy)' check around it. (ahem; a trivial fix for this -rc series; sorry for this oversight.) With it applied, both PCI device remove and EEH recovery works fine.

scsi: qla2xxx: fix invalid DMA access after command aborts in PCI device remove If a command is aborted in the kernel but not in the adapter, it might be considered complete and its DMA memory released, but it is still alive in the adapter, which will trigger an invalid DMA access upon its completion (in the DMA operations to deliver the command response to the driver). On powerpc platforms with IOMMU/EEH capabilities, the problem is observed during PCI device removal with ongoing IO requests -- which might trigger an EEH event very often, pointing to a 'TCE Request Page Access Error'. In that path, which is qla2x00_remove_one(), the commands are aborted in qla2x00_abort_all_cmds(), which does not perform an abort in the adapter as is done in qla2xxx_eh_abort() for example. So, this patch changes qla2x00_abort_all_cmds() to abort commands in the adapter too, with a call to qla2xxx_eh_abort(), which already implements all the logic to submit abort requests and handle responses.

scsi: qla2xxx: Fix scsi scan hang triggered if adapter fails during init A system can get hung task timeouts if a qlogic board fails during initialization (if the board breaks again or fails the init). The hang involves the scsi scan. In a nutshell, since commit beb9e315e6e0 ("qla2xxx: Prevent removal and board_disable race"): ...it is possible to have freed ha (base_vha->hw) early by a call to qla2x00_remove_one when pdev->enable_cnt equals zero: if (!atomic_read(&pdev->enable_cnt)) { scsi_host_put(base_vha->host); kfree(ha); pci_set_drvdata(pdev, NULL); return; Almost always, the scsi_host_put above frees the vha structure (attached to the end of the Scsi_Host we're putting) since it's the last put, and life is good. However, if we are entering this routine because the adapter has broken sometime during initialization AND a scsi scan is already in progress (and has done its own scsi_host_get), vha will not be freed. What's worse, the scsi scan will access the freed ha structure through qla2xxx_scan_finished: if (time > vha->hw->loop_reset_delay * HZ) return 1; The scsi scan keeps checking to see if a scan is complete by calling qla2xxx_scan_finished. There is a timeout value that limits the length of time a scan can take (hw->loop_reset_delay, usually set to 5 seconds), but this definition is in the data structure (hw) that can get freed early. This can yield unpredictable results, the worst of which is that the scsi scan can hang indefinitely. This happens when the freed structure gets reused and loop_reset_delay gets overwritten with garbage, which the scan obliviously uses as its timeout value. The fix for this is simple: at the top of qla2xxx_scan_finished, check for the UNLOADING bit in the vha structure (_vha is not freed at this point). If UNLOADING is set, we exit the scan for this adapter immediately. After this last reference to the ha structure, we'll exit the scan for this adapter, and continue on. This problem is hard to hit, but I have run into it doing negative testing many times now (with a test specifically designed to bring it out), so I can verify that this fix works. My testing has been against a RHEL7 driver variant, but the bug and patch are equally relevant to to the upstream driver.

qla2xxx: Wait for all conflicts before ack'ing PLOGI Until now ack'ing of a new PLOGI has only been delayed if there was an existing session for the same WWN. Ack was released when the session deletion completed. If there was another WWN session with the same fc_id/loop_id pair (aka "conflicting session"), PLOGI was still ack'ed immediately. This potentially caused a problem when old session deletion logged fc_id/loop_id out of FW after new session has been established. Two work-arounds were attempted before: 1. Dropping PLOGIs until conflicting session goes away. 2. Detecting initiator being logged out of FW and issuing LOGO to force re-login. This patch introduces proper solution to the problem where PLOGI is held until either existing session with same WWN or any conflicting session goes away. Mechanism supports one session holding two PLOGI acks as well as one PLOGI ack being held by many sessions.

qla2xxx: Delete session if initiator is gone from FW 1. Initiator A is logged in with fc_id(1)/loop_id(1) 2. Initiator A re-logs in with fc_id(2)/loop_id(2) 3. Part of old session deletion async logoout for 1/1 is queued 4. Initiator B logs in with fc_id(1)/loop_id(1), starts passing data and creates session. 5. Async logo from 3 is processed by DPC and sent to FW Now initiator B has the session but is logged out from FW. This condition is detected first with CTIO error 29 at which point we should delete current session. During session deletion we will send LOGO to initiator to force re-login. Under rare circumstances initiator might be logged out of FW, not have driver session, but still think it's logged in. E.g. the above sequence plus session deletion due to re-config. Incoming commands will fail to create local session because initiator is not found in FW. In this case we also issue LOGO to initiator to force him re-login. Finally this patch fixes exchange leak when commands where received in logged out state. In this case loop_id must be set to FFFF when corresponding exchange is terminated. The patch modifies exchange termination to always use FFFF, since in certain scenarios it's impossible to tell whether command was received in logged in or logged out state.

We pretty much only get a few more sysfs entries for each port, but all that information is already available from /sys/kernel/debug/target/qla-session-X 2. It already only works in private-loop mode. By disabling we'll be getting more uniform behavior with fabric mode. 3. It creates complications for the new PLOGI handling mechanism: scsi_transport_fc port deletion timer could race with new session from initiator and cause logout after successful login.

As such the decision to remove disappeared fc port's session could be stale, because a new login sequence has occurred since and created a brand new session. Previous mechanism of dealing with this by delaying deletion request was prone to erroneous deletions if the event that was supposed to cancel the deletion never arrived or has been delayed in processing. New mechanism relies on a time-like generation counter to serialize RSCN updates relative to ELS/IO updates.

qla2xxx: fix busy wait regression Commit e05fe29248 (qla2xxx: Honor FCP_RSP retry delay timer field.) causes systems to busy-wait for about 3 minutes after boot prior to detecting SAN disks. During this wait period one kworker is running full-time (though /proc/<pid>/stack has no useful data). Another kworker is waiting for IO to complete during that whole time period. Looking at drivers/scsi/qla2xxx/qla_os.c, fcport->retry_delay_timestamp has a special value of 0 though that 0 value forces system to wait when jiffies is very large value (e.g. 4294952605 - "negative" value when signed on 32bit systems).

scsi: don't set tagging state from scsi_adjust_queue_depth Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

qla2xxx: Prevent probe and board_disable race The PCI register read checking introduced in commit fe1b806f4f71 ("qla2xxx: Disable adapter when we encounter a PCI disconnect") is active during driver probe. Hold off scheduling any board removal until the driver probe has completed. This ensures that the the board_disable work structure is initialized and more importantly, avoids racing qla2x00_probe_one.

qla2xxx: Prevent removal and board_disable race Introduce mutual exclusion between the qla2xxx_remove_one PCI driver callback and qla2x00_disable_board_on_pci_error, which is scheduled as board_disable work by qla2x00_check_reg{32,16}_for_disconnect: * Leave the driver-specific data attached to the underlying PCI device intact in qla2x00_disable_board_on_pci_error, so that qla2x00_remove_one has enough breadcrumbs to determine that any board_disable work has been completed. * In qla2xxx_remove_one, set a bit to prevent any subsequent board_disable work from scheduling, then cancel and wait until pending work has completed. * Reuse the PCI device enable count check in qla2x00_remove_one to determine if board_disable has occured. The original purpose of this check was unnecessary since the driver remove function wasn't called when the probe fails.

SCSI: remove unnecessary pci_set_drvdata() Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

[SCSI] qla2xxx: Correct race in loop_state assignment during reset handling. There's a subtle race in the loop/bus-reset handling whereby a VHA's loop-state can get incorrectly set to 'down' after the loop-reset and firmware's completion of link re-negotiation. The original code incorrectly assumes that firmware AENs would arrive only after mailbox-command execution to initiate the link-flap. Here's a good case with the old code (AENs arrive after mailbox-command completion): qla2xxx [0000:03:00.1]-8012:91: BUS RESET ISSUED nexus=91:0:4. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010100. qla2xxx [0000:03:00.1]-580e:91: Asynchronous P2P MODE received. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010400. qla2xxx [0000:03:00.1]-802b:91: BUS RESET SUCCEEDED nexus=91:0:4. qla2xxx [0000:03:00.1]-480b:91: Reset marker scheduled. qla2xxx [0000:03:00.1]-5812:91: Port database changed ffff 0006 0000. qla2xxx [0000:03:00.1]-505f:91: Link is operational (4 Gbps). qla2xxx [0000:03:00.1]-480c:91: Reset marker end. qla2xxx [0000:03:00.1]-480f:91: Loop resync scheduled. qla2xxx [0000:03:00.1]-8837:91: F/W Ready - OK. qla2xxx [0000:03:00.1]-883a:91: fw_state=3 (7, 0, 0, 0) curr time=170b8f315. qla2xxx [0000:03:00.1]-280e:91: HBA in F P2P topology. qla2xxx [0000:03:00.1]-2812:91: qla2x00_configure_hba success qla2xxx [0000:03:00.1]-2814:91: Configure loop -- dpc flags = 0x5260. notice how the 'Port database changed' (8014) arrived after the bus-reset handler completed 'BUS RESET SUCCEEDED'.

[SCSI] qla2xxx: Test and clear FCPORT_UPDATE_NEEDED atomically. When the qla2xxx driver loses access to multiple, remote ports, there is a race condition which can occur which will keep the request stuck on a scsi request queue indefinitely. This bad state occurred do to a race condition with how the FCPORT_UPDATE_NEEDED bit is set in qla2x00_schedule_rport_del(), and how it is cleared in qla2x00_do_dpc(). The problem port has its drport pointer set, but it has never been processed by the driver to inform the fc transport that the port has been lost. qla2x00_schedule_rport_del() sets drport, and then sets the FCPORT_UPDATE_NEEDED bit. In qla2x00_do_dpc(), the port lists are walked and any drport pointer is handled and the fc transport informed of the port loss, then the FCPORT_UPDATE_NEEDED bit is cleared. This leaves a race where the dpc thread is processing one port removal, another port removal is marked with a call to qla2x00_schedule_rport_del(), and the dpc thread clears the bit for both removals, even though only the first removal was actually handled. Until another event occurs to set FCPORT_UPDATE_NEEDED, the later port removal is never finished and qla2xxx stays in a bad state which causes requests to become stuck on request queues. This patch updates the driver to test and clear FCPORT_UPDATE_NEEDED atomically. This ensures the port state changes are processed and not lost.

[SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx series Add LLD target mode for >= 24xx series HW. This code was originally based on external qla2x00t module based on 8.02.01-k4, and has been refactored to push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c. The implementation uses internal workqueues for I/O context submission into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for external interaction to allow qla2xxx LDD to function without direct target-core dependencies: It also enables qla_target.c usage within existing qla2xxx LLD code. This includes: *) Addition of target mode specific members to existing data structures in qla_def.h and struct qla_hw_data->tgt_ops using qla_target.h:struct qla_tgt_func_tmpl *) Addition of struct qla_tgt_func_tmpl and direct calls into qla_target.c logic w/ qlt_* prefixed functions. *) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and qla2x00_issue_marker() for handling request/response queue processing for target mode operation *) Addition of various qla_tgt_mode_enabled() logic checks in qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(), qla2x00_abort_isp(), qla24xx_modify_vp_config(), and qla2x00_vp_abort_isp(). By default the new qlini_mode module parameter is setting initiator-mode to 'enabled' in order for 'modprobe qla2xxx' to continue to function as expected in initiator only mode. Enabling target-mode operation will currently require a: modprobe qla2xxx qlini_mode="disabled" in order to explictly disabled initiator mode and allow target-mode to be enabled via tcm_qla2xxx configfs fabric callers. (nab: Convert to qlini_mode='enabled' by default in qla_target.c) (joern: Remove loop_id from qla_tgt_make_local_sess() arguments + Remove unused s_id + fix s_id endianness bug + simplify qla_tgt_abort_work) (gerard: fix section __exit mismatch in qla_tgt_exit) (arun: Capture ATIO queue during firmware dump + Send SCR in target mode + Target mode review comments) (roland: Don't create duplicate target sessions to address tearing down ACLs with IO in flight + Add missing call to qlt_fc_port_deleted call during qla2x00_schedule_rport_del timeout) Signed-off-by: Nicholas A.

I debugged this down to the abort handling improperly treating a command of type SRB_ADISC_CMD as if it had a bsg_job to complete when that command actually uses the iocb_cmd part of the union. (I guess to hit this one has to unload the module while the async FC initialization is still in progress) It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT, SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.

[SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting. This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.

[SCSI] qla2xxx: Return DID_NO_CONNECT when FC device is lost. If the target device gets lost, this fix is needed, as it causes negative unintended responses on basic I/O tests. If the target device gets lost, the upstream qla2xxx driver returns SCSI_MLQUEUE_TARGET_BUSY which causes an immediate retry without drop in the number of allowed retries. This semantic change, as a result of removing FC_DEVICE_LOST check is reasonable, as it only extends a short transitional period, until the transport is called to notify that the rport as lost (fc_remote_port_delete()). Once transport notification is done, fc_remote_port_chkready() check will take over.

SCSI host lock push-down Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

llseek: automatically add .llseek fop All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

[SCSI] qla2xxx: ensure flash operation and host reset via sg_reset are mutually exclusive The problem occurring is a hw-race where there's an outstanding read-flash operation occurring while the chip is being reset (done via an sg_reset script). After the chip is paused, the read-flash operation never completes and the DPC thread, while trying to complete the reset, is never able to recover, as the HW appears to be hung... The fix is to wait for outstanding flash operation prior to doing a sg_reset -h. And to wait for reset to complete before any flash operations. Note, during the wait, if any of the operation (reset/flash) does not complete, failure is returned to the upper layer. The upper layer either need to fail or retry.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[SCSI] modify change_queue_depth to take in reason why it is being called This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it.

[SCSI] qla2xxx: Conditionally disable automatic queue full tracking. Changing a lun's queue depth (/sys/block/sdX/device/queue_depth) isn't sticky when the device is connected via a QLogic fibre channel adapter. The QLogic qla2xxx fibre channel driver dynamically adjusts a lun's queue depth. If a user has a specific need to limit the number of commands issued to a lun (say a tape drive, or a shared raid where the total commands issued to all luns is limited at the controller level, for example) and writes a limiting value to /sys/block/sdXX/device/queue_depth, the qla2xxx driver will silently and gradually increase the queue depth back to the driver limit of ql2xmaxqdepth. While reducing this value (module parameter) or increasing the interval between ramp ups (ql2xqfullrampup) offers the potential for a work around it would be better to have the option of just disabling the dynamic adjustment of queue depth. This patch implements an "off switch" as a module parameter.

[SCSI] qla2xxx: Return a FAILED status when abort mailbox-command fails. Mike Reed noted (https://bugzilla.novell.com/show_bug.cgi?id=421330) that the driver was incorrectly returning a SUCCESS status if the driver's request to the firmware to abort a command failed. By doing so, the mid-layer believed, incorrectly, that the command has completed and has been returned (ultimately clearing scsi_cmnd.request_buffer) yet the driver still has the command. What should correctly happen is a mid-layer escalation (device-reset, etc.) of recovery during which the driver will eventually return the outstanding commands to the mid-layer.

[SCSI] qla2xxx: Explicitly tear-down vports during PCI remove_one(). During internal testing, we've seen issues (hangs) with the 'deferred' vport tear-down-processing typically accompanied with the fc_remove_host() call. This is due to the current implementation's back-end vport handling being performed by the physical-HA's DPC thread where premature shutdown could lead to latent vport requests without a processor. This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

Commit 63a8651f2548c6bb5132c0b4e7dad4f57a9274db ([SCSI] qla2xxx: Correct infinite-login-retry issue.) introduced a small regression where a successful relogin would result in an fcport's loop_id to be incorrectly reset to FC_NO_LOOP_ID.

[SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support. FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

[SCSI] qla2xxx: defer topology discovery to DPC thread during initialization. Modify intialization semantics: - perform basic hardware configuration only (as usual) - allocate resources - load and execute firmware - defer link (transport) negotiations to the DPC thread - again the code in qla2x00_initialize_adapter() to stall probe() completion was needed for legacy-style scanning. - DPC thread stalls until probe() complete. - before probe() completes, set DPC flags to perform loop-resync logic (similar to what's done during cable-insertion/removal). Benefits: user does not have to wait 20+ seconds in case the FC cable is unplugged during driver load, code consolidation (removal of redundant link negotiation logic during initialize_adaoter()), and finilly, the driver no longer needs to defer the fc_remote_port_add() calls to hold off lun-scanning prior to returning from the probe() function.

[SCSI] qla2xxx: Workaround D3 power-management issues. Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.

By taking advantage of the higher link rate, the HBA can maximize bandwidth utilization in a heterogeneous multi-speed SAN. Within a fabric topology, port speed detection is done via a Name Server command (GFPN_ID) followed by a Fabric Management command (GPSC). In an FCAL/N2N topology, port speed is based on the HBA link-rate. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

[SCSI] qla2xxx: Fix to allow to reset devices using sg interface (sg_reset). Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices.

[SCSI] qla2xxx: Correct synchronization issues during rport addition/deletion. The driver can typically detect port-loss during an interrupt context (i.e. via interrogation of a status IOCB's completion status [CS_PORT_LOGGED_OUT]. Due to the calling requirements of the fc_rport APIs, the driver would defer removal of the device to the default workqueue. If the work-item was preceded by an event which caused the port to obtain visibility (relogin successful, target re-logged into the topology), deferred removal could inadvertently drop the rport. The code also no longer defers removal via the default workqueue, instead opting for use of the driver's own DPC thread.

[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine. Given the semantic changes in both the device-model and fc-transport APIs, the driver's handling of port-type RSCNs via a series of ADISCs and PLOGIs can cause series of badness ranging from unexpectedly device loss to devices not being discovered. In the interim, disable (via a module-parameter) this feature and allow RSCN management to continue to occur within the driver's DPC thread.

This will be the default behaviour going forward until the embedded firmware-binary images are removed from the upstream kernel. Upon request, the driver caches the firmware image until the driver is unloaded. NOTE: The option is present to allow the user to continue to use the firmware-loader modules, but, should be considered deprecated.

[SCSI] update fc_transport for removal of block/unblock functions We recently went back to implement a board reset. When we perform the reset, we wanted to tear down the internal data structures and rebuild them. Unfortunately, when it came to the rport structure, things were odd. If we deleted them, the scsi targets and sdevs would be torn down. Not a good thing for a temporary reset. We could block the rports, but we either maintain the internal structures to keep the rport reference (perhaps even replicating what's in the transport), or we have to fatten the fc transport with new search routines to find the rport (and deal with a case of a dangling rport that the driver forgets). It dawned on me that we had actually reached this state incorrectly. When the fc transport first started, we did the block/unblock first, then added the rport interface. The purpose of block/unblock is to hide the temporary disappearance of the rport (e.g. being deleted, then readded). Why are we making the driver do the block/unblock ? We should be making the transport have only an rport add/delete, and the let the transport handle the block/unblock. So... This patch removes the existing fc_remote_port_block/unblock functions. It moves the block/unblock functionality into the fc_remote_port_add/delete functions. Updates for the lpfc driver are included. Qlogic driver updates are also enclosed, thanks to the contributions of Andrew Vasquez. [Note: the qla2xxx changes are relative to the scsi-misc-2.6 tree as of this morning - which does not include the recent patches sent by Andrew]. The zfcp driver does not use the block/unblock functions. One last comment: The resulting behavior feels very clean. The LLDD is concerned only with add/delete, which corresponds to the physical disappearance. However, the fact that the scsi target and sdevs are not immediately torn down after the LLDD calls delete causes an interesting scenario... the midlayer can call the xxx_slave_alloc and xxx_queuecommand functions with a sdev that is at the location the rport used to be. The driver must validate the device exists when it first enters these functions. In thinking about it, this has always been the case for the LLDD and these routines. The existing drivers already check for existence. However, this highlights that simple validation via data structure dereferencing needs to be watched. To deal with this, a new transport function, fc_remote_port_chkready() was created that LLDDs should call when they first enter these two routines. It validates the rport state, and returns a scsi result which could be returned. In addition to solving the above, it also creates consistent behavior from the LLDD's when the block and deletes are occuring.

[SCSI] qla2xxx: Add support to dynamically enable/disable ZIO. ISP23xx and ISP24xx chips have support for an adaptive method of posting SCSI command completions for multiple SCSI commands during a single system interrupt. SCSI commands are placed on the system response queue without interrupting the host until 1) a delay timer expires; or 2) a SCSI command completes with an error. As long as the host software (qla2xxx) services the response queue for completions (this polling is done during queuecommand()) within the 'delay timer' period, the firmware will not generate system interrupt.

[PATCH] qlogic lockup fix If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started yet. It does wait_for_completion() against an uninitialised completion struct and the kernel hangs up. Fix it by initialising ha->dpc_pid a bit earlier.
