scsi: qla2xxx: Flush mailbox commands on chip reset Fix race condition between Interrupt thread and Chip reset thread in trying to flush the same mailbox. With the race condition, the "ha->mbx_intr_comp" will get an extra complete() call. The extra complete call create erroneous mailbox timeout condition when the next mailbox is sent where the mailbox call does not wait for interrupt to arrive. Instead, it advances without waiting. Add lock protection around the check for mailbox completion.

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: Fix hang when issuing nvme disconnect-all in NPIV In NPIV environment, a NPIV host may use a queue pair created by base host or other NPIVs, so the check for a queue pair created by this NPIV is not correct, and can cause an abort to fail, which in turn means the NVME command not returned. This leads to hang in nvme_fc layer in nvme_fc_delete_association() which waits for all I/Os to be returned, which is seen as hang in the application.

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.

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.

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: Fix sparse annotations This patch removes 21 casts between an __iomem pointer type and another data type but also introduces five new casts (see also the casts with "__force"). Although this patch does not change any functionality, IMHO the code with __force casts needs further review.

[SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routines The driver uses ha->mbx_cmd_flags variable to pass information between its ISR and mailbox routines, however, it does so without the protection of any locks. Under certain conditions, this can lead to multiple mailbox command completions being signaled, which, in turn, leads to a false mailbox timeout error for the subsequently issued mailbox command. The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz card during card initialization, resulting in card initialization failure.

[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: 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: Fix cpu-affinity usage for non-capable ISPs. The TMFs used for pre-24xx ISPs incorrectly assumed 'cpu' tag data could be valid. These chips have no multi-q/cpu-affinity support.

[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.

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] qla2xxx: add support for multi-queue adapter Following changes have been made. 1. qla_hw_data structure holds an array for request queue pointers, and an array for response queue pointers. 2. The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.

[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: Correct usage of inconsistent timeout values while issuing ELS commands. The original code would incorrectly hardcode ELS timeout values rather than using the traditional '2 * r_a_tov' value. In some cases, the hardcoded values would be larger than the mailbox-command-timeout and result in a needless BIG_HAMMER (ISP reset), the typical recovery mechanism employed in such cases. The second defect in the original code was in the assignment of the default 'ha->r_a_tov' to twice the traditional value. Correct this by setting the value to 10 seconds.

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: Correct FCAL login retry logic for ISP24xx. ISP24XX FW does not support Mbx 0x74 ie Login Local Port. Added the equivalent code for ISP24XX ie to relogin in non fabric case for ISP24XX use login iocb.

[PATCH] qla2xxx: Pass input-buffer length to Get-ID-List mailbox command. Recent ISP24xx firmwares require that mailbox register 8 be set to the maximum number of bytes to transfer during DMA copying of the list. We safely set this value to zero (infinite), since the call is *only* made in FCAL topologies.

[SCSI] qla2xxx: Correct excessive delay during LOAD-RISC-RAM mailbox command. Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.

[SCSI] qla2xxx: Use msleep() as delay during ISP polling. Mailbox commands are polled for completion during ISP initialization. During potentially 'long' mailbox commands (i.e. fabric login), we really don't want a busy-wait delay to potentially trigger a (benign) soft-lockup BUG().

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!
