scsi: qla2xxx: Fix firmware resource tracking The storage was not draining I/Os and the work load was not spread out across different CPUs evenly. This led to firmware resource counters getting overrun on the busy CPU. This overrun prevented error recovery from happening in a timely manner. By switching the counter to atomic, it allows the count to be little more accurate to prevent the overrun.

scsi: qla2xxx: Fix NULL pointer dereference in target mode When target mode is enabled, the pci_irq_get_affinity() function may return a NULL value in qla_mapq_init_qp_cpu_map() due to the qla24xx_enable_msix() code that handles IRQ settings for target mode. This leads to a crash due to a NULL pointer dereference. This patch fixes the issue by adding a check for the NULL value returned by pci_irq_get_affinity() and introducing a 'cpu_mapped' boolean flag to the qla_qpair structure, ensuring that the qpair's CPU affinity is updated when it has not been mapped to a CPU.

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.

treewide: Replace zero-length arrays with flexible-array members There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ...

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 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.

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 qla82xx-specific code qla82xx_idc_lock() spins on a certain hardware state until it's updated. At the end of each spin, if in_interrupt() is true, it does 20 loops of cpu_relax(). Otherwise, it yields the CPU. While in_interrupt() is ill-defined and does not provide what the name suggests, it is not needed here: qla82xx_idc_lock() is always called from process context. Below is an analysis of its callers, in order of appearance: - qla_nx.c: qla82xx_device_bootstrap(), only called by qla82xx_device_state_handler(), has multiple msleep()s. - qla_nx.c: qla82xx_need_qsnt_handler(), has one second msleep() - qla_nx.c: qla82xx_wait_for_state_change(), one second msleep() - qla_nx.c: qla82xx_need_reset_handler(), can sleep up to 10 seconds - qla_nx.c: qla82xx_device_state_handler(), has multiple msleep()s - qla_nx.c: qla82xx_abort_isp(), if it's a qla82xx controller, calls qla82xx_device_state_handler(), which sleeps. It's also bound to isp_operations ->abort_isp() hook, where all the callers are in process context. - qla_nx.c: qla82xx_beacon_on(), bound to isp_operations ->beacon_on() hook. That hook is only called once, in a mutex locked context, from qla2x00_beacon_store(). - qla_nx.c: qla82xx_beacon_off(), bound to isp_operations ->beacon_off() hook. Like ->beacon_on(), it's only called once, in a mutex locked context, from qla2x00_beacon_store(). - qla_nx.c: qla82xx_fw_dump(), calls qla2x00_wait_for_chip_reset(), which has msleep() in a loop. It is bound to isp_operations ->fw_dump() hook. That hook *is* called from atomic context at qla_isr.c by multiple interrupt handlers. Nonetheless, it's other controllers interrupt handlers, and not the qla82xx. - qla82xx_msix_default() and qla82xx_msix_rsp_q() call qla24xx_process_response_queue() which doesn't implement the firmware dumping. - qla_attr.c: qla2x00_sysfs_write_fw_dump(), and qla2x00_sysfs_write_reset(), process-context sysfs ->write() hooks. - qla_os.c: qla2x00_probe_one(). PCI ->probe(), process context. - qla_os.c: qla2x00_clear_drv_active(), called solely from qla2x00_remove_one(), which is PCI ->remove() hook, process context. - qla_os.c: qla2x00_do_dpc(), kthread function, process context. Remove the in_interrupt() check. Change qla82xx_idc_lock() specification to a purely process-context function. Mark it with "Context: task, might sleep". Change qla82xx_idc_lock() implementation to sleep 100ms, instead of a schedule(), for each spin. This is more deterministic, and it matches the other qla models idc_lock() functions.

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: 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.

scsi: qla2xxx: Use explicit LOGO in target mode Target makes implicit LOGO on session teardown. LOGO ELS is not send on the wire and initiator is not aware that target no longer wants talking to it. Initiator keeps sending I/O requests, target responds with BA_RJT, they time out and then initiator sends ABORT TASK (ABTS-LS). Current behaviour incurs unneeded I/O timeout and can be fixed for some initiators by making explicit LOGO on session deletion.

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: Fix premature timer expiration For any qla2xxx async command, the SRB buffer is used to send it. In setting up the SRB buffer, the timer for this command is started before all memory allocation has finished. Under low memory pressure, memory alloc can go to sleep and not wake up before the timer expires. Once timer has expired, the timer thread will access uninitialize fields resulting into NULL pointer crash. This patch fixes this crash by moving the start of timer after everything is setup. backtrace shows following PID: 3720 TASK: ffff996928401040 CPU: 0 COMMAND: "qla2xxx_1_dpc" 0 [ffff99652751b698] __schedule at ffffffff965676c7 1 [ffff99652751b728] schedule at ffffffff96567bc9 2 [ffff99652751b738] schedule_timeout at ffffffff965655e8 3 [ffff99652751b7e0] io_schedule_timeout at ffffffff9656726d 4 [ffff99652751b810] congestion_wait at ffffffff95fd8d12 5 [ffff99652751b870] isolate_migratepages_range at ffffffff95fddaf3 6 [ffff99652751b930] compact_zone at ffffffff95fdde96 7 [ffff99652751b980] compact_zone_order at ffffffff95fde0bc 8 [ffff99652751ba20] try_to_compact_pages at ffffffff95fde481 9 [ffff99652751ba80] __alloc_pages_direct_compact at ffffffff9655cc31 10 [ffff99652751bae0] __alloc_pages_slowpath at ffffffff9655d101 11 [ffff99652751bbd0] __alloc_pages_nodemask at ffffffff95fc0e95 12 [ffff99652751bc80] dma_generic_alloc_coherent at ffffffff95e3217f 13 [ffff99652751bcc8] x86_swiotlb_alloc_coherent at ffffffff95e6b7a1 14 [ffff99652751bcf8] qla2x00_rft_id at ffffffffc055b5e0 [qla2xxx] 15 [ffff99652751bd50] qla2x00_loop_resync at ffffffffc0533e71 [qla2xxx] 16 [ffff99652751be68] qla2x00_do_dpc at ffffffffc05210ca [qla2xxx] PID: 0 TASK: ffffffff96a18480 CPU: 0 COMMAND: "swapper/0" 0 [ffff99652fc03ae0] machine_kexec at ffffffff95e63674 1 [ffff99652fc03b40] __crash_kexec at ffffffff95f1ce12 2 [ffff99652fc03c10] crash_kexec at ffffffff95f1cf00 3 [ffff99652fc03c28] oops_end at ffffffff9656c758 4 [ffff99652fc03c50] no_context at ffffffff9655aa7e 5 [ffff99652fc03ca0] __bad_area_nosemaphore at ffffffff9655ab15 6 [ffff99652fc03cf0] bad_area_nosemaphore at ffffffff9655ac86 7 [ffff99652fc03d00] __do_page_fault at ffffffff9656f6b0 8 [ffff99652fc03d70] do_page_fault at ffffffff9656f915 9 [ffff99652fc03da0] page_fault at ffffffff9656b758 [exception RIP: unknown or invalid address] RIP: 0000000000000000 RSP: ffff99652fc03e50 RFLAGS: 00010202 RAX: 0000000000000000 RBX: ffff99652b79a600 RCX: ffff99652b79a760 RDX: ffff99652b79a600 RSI: ffffffffc0525ad0 RDI: ffff99652b79a600 RBP: ffff99652fc03e60 R8: ffffffff96a18a18 R9: ffffffff96ee3c00 R10: 0000000000000002 R11: ffff99652fc03de8 R12: ffff99652b79a760 R13: 0000000000000100 R14: ffffffffc0525ad0 R15: ffff99652b79a600 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 10 [ffff99652fc03e50] qla2x00_sp_timeout at ffffffffc0525af8 [qla2xxx] 11 [ffff99652fc03e68] call_timer_fn at ffffffff95ea7f58 12 [ffff99652fc03ea0] run_timer_softirq at ffffffff95eaa3bd 13 [ffff99652fc03f18] __do_softirq at ffffffff95ea0f05 14 [ffff99652fc03f88] call_softirq at ffffffff9657832c 15 [ffff99652fc03fa0] do_softirq at ffffffff95e2e675 16 [ffff99652fc03fc0] irq_exit at ffffffff95ea1285 17 [ffff99652fc03fd8] smp_apic_timer_interrupt at ffffffff965796c8 18 [ffff99652fc03ff0] apic_timer_interrupt at ffffffff96575df2 Signed-off-by: Quinn Tran <qutran@marvell.com> Signed-off-by: Himanshu Madhani <hmadhani@marvell.com> Signed-off-by: Martin K.

scsi: scsi_transport_fc: nvme: display FC-NVMe port roles Currently the FC-NVMe driver is leverating the SCSI FC transport class to access the remote ports. Which means that all FC-NVMe remote ports will be visible to the fc transport layer, but due to missing definitions the port roles will always be 'unknown'. This patch adds the missing definitions to the fc transport class to that the port roles are correctly displayed.

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().

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.

Usage: modprobe qla2xxx qlini_mode=disabled ql2xuctrlirq=1 mount -t debugfs none /sys/kernel/debug echo 2 > /sys/kernel/debug/qla2xxx/qla2xxx_[host num]/naqp echo [cpu id] > /proc/irq/[irq id]/smp_affinity_list Signed-off-by: Quinn Tran <quinn.tran@cavium.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Signed-off-by: Martin K.

scsi: qla2xxx: Fix mailbox failure while deleting Queue pairs In target mode driver, queue pairs are not created during driver load time, instead they are created at the configuration time after chip reset. If a user tries to load/unload driver after queue pairs are created, then there would be mailbox failure, while deleting queue pairs. Flag is added to check if queue pairs are created or not.

scsi: qla2xxx: Add ql2xiniexchg parameter Previously, the ql2xexchoffld module parameter was used to control the max number of exchanges to be offload onto host memory. Module parameter ql_dm_tgt_ex_pct was used to control the percentage of exchanges allocated to the Target side. With this patch, module parameter ql_dm_tgt_ex_pct is no longer used to control exchanges for the driver. New module parameter ql2xiniexchg is added to control exchanges between target mode and initiator mode. With the updated module parameters, users can control the exact number of exchanges for either Initiator or Target. The exchange offload feature will be automatically enabled when the total number of exchanges exceeds 2048 limit.

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.

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.

qla2xxx: added sess generations to detect RSCN update races RSCN processing in qla2xxx driver can run in parallel with ELS/IO processing. 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.

If we become disconnected from the PCI bus/PCIe fabric, there can be long delays in register reads which can cause erroneous decisions to be made and cause a soft lockup if a lock is held too long.

(It is not clear to me which array triggers this warning and by how much GCC thinks the subscript is above its bounds. Neither is it clear to me why comparable code in these two functions doesn't trigger this warning.) An easy way to silence these warnings is to use preprocessor macros and strncpy, as that apparently gives GCC enough information to keep track of array bounds.

[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.

[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: Handle outstanding mbx cmds on hung f/w scenarios. Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.

[SCSI] qla2xxx: Support for asynchronous TM and Marker IOCBs. Currently we can only issue the task management (TM) commands via the mailbox mechanism. This is a limitation, since only one mailbox command can be issued at a time. The purpose of this effort is to provide support for issuing and processing the respose to TM and Marker IOCBs asynchronously. Towards achieving this, the consolidated srb architecture that is currently used for BSG and IOCB/Logio commands has been enhanced and used.

[SCSI] qla2xxx: Refactor qla data structures Following changes have been made to the qla2xxx FC driver in preparation for the multi- queue and future SR IOV hardware. 1. scsi_qla_host structure has been changed to contain scsi host specific data only. 2. A new structure, qla_hw_data is created to contain HBA specific hardware data. 3. Request and response IO specific data strucures are created. 4. The global list of fcports for the hba is not maintained anymore, instead a fcport list is construted on per scsi_qla_host.

[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.

[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.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[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] 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.

[PATCH] qla2xxx: remove internal queuing... Remove internal command queuing from the driver. As is, this driver cannot tolerate cable-pulls as I/Os will begin to fail by the upper layers. o Should be used in conjuction with the 11-fc_rport_adds_2.diff patch. o Removes qla_listops.h file -- no longer needed.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
