Adds more cases to do flogi retry, now also retry on getting bad response due to either no ELS response or flogi response payload length not large enough. In those cases flogi was not retried and that was leaving lport offline. Signed-off-by:

Currently timer delay is large and is using msleep to avoid avoid exchanges collision across lport reset, so instead do this by initializing exches pool indexes during reset also. Signed-off-by:

Its checked after skb freed, so instead have fh_type cached and then check FC_TYPE_BLS against cached fh_type value. This wrong check was causing double exch locking as reported by Bhanu at https://lists.open-fcoe.org/pipermail/devel/2011-October/011793.htmlSigned-off-by:

Fixes bug where max_concurr_spinup oem parameter should be overriden by max_concurr_spinup user parameter. Override should happen only when max_concurr_spinup user parameter is specified in command line (greater than 0). Also this fix shortens variables representing max_conxurr_spinup for oem and user parameters. Signed-off-by:

The initial bcn filtering implementation was validated on a kernel baseline that predated the switch to new libata error handling. Also, prior to that conversion we borrowed the mvsas MVS_DEV_EH approach to prevent the unwanted extra ap->ops->phy_reset(ap) that occurred in the ata_bus_probe() path. After the conversion to new libata eh resets at discovery are more frequent and get filtered prematurely by IDEV_EH. The result is that our bcn filtering has been blocked from running and at discovery and it appears to stall discovery completion to the point of triggering hung task timeouts. So, revert the implementation for now. When it returns it will go into libsas proper. The domain rediscovery that takes place due to ->lldd_I_T_nexus_reset() events should now be properly waited for by the ata_port_wait_eh() call in ata_port_probe(). So the hard coded delay in the isci ->lldd_I_T_nexus_reset() and other libsas drivers should help debounce the libsas thread from seeing temporary device removals. Signed-off-by:

A hard reset can timeout before or after the last phy in the port goes away. If after, then notify the OS that the last phy has failed. The recovery for the failed hard reset has been removed. This recovery code was unecessary in that the link would recover from the failure normally by a new link reset sequence or hotplug of the remote device. Signed-off-by:

libsas uses the LLDD abort task interface to handle I/O timeouts in the SATA/STP and SMP discovery paths, so this change will terminate STP/SMP requests. Also, if the device is gone, the lldd will prevent libsas from further escalations in the error handler. Signed-off-by:

The LLDD needs to obtain a reference to the device through the request itself and not through the domain_device, because the domain_device.lldd_dev is set to NULL early in the lldd_dev_gone call. This relies on the fact that the isci_remote_device object is keeping a seperate reference count of outstanding requests. TODO: unify the request count tracking with the isci_remote_device kref. The failure signature of this condition looks like the following log, where the important bits are the call to lldd_dev_gone followed by a crash in isci_terminate_request_core: [ 229.151541] isci 0000:0b:00.0: isci_remote_device_gone: domain_device = ffff8801492d4800, isci_device = ffff880143c657d0, isci_port = ffff880143c63658 [ 229.166007] isci 0000:0b:00.0: isci_remote_device_stop: isci_device = ffff880143c657d0 [ 229.175317] isci 0000:0b:00.0: isci_terminate_pending_requests: idev=ffff880143c657d0 request=ffff88014741f000; task=ffff8801470f46c0 old_state=2 [ 229.189702] isci 0000:0b:00.0: isci_terminate_request_core: device = ffff880143c657d0; request = ffff88014741f000 [ 229.201339] isci 0000:0b:00.0: isci_terminate_request_core: before completion wait (ffff88014741f000/ffff880149715ad0) [ 229.213414] isci 0000:0b:00.0: sci_controller_process_completions: completion queue entry:0x8000a0e9 [ 229.214401] BUG: unable to handle kernel NULL pointer dereference at 0000000000000228 [ 229.214401] IP:jdskirvi-testlbo [<ffffffffa00a58be>] sci_request_completed_state_enter+0x50/0xafb [isci] [ 229.214401] PGD 13d19e067 PUD 13d104067 PMD 0 [ 229.214401] Oops: 0000 [#1] SMP [ 229.214401] CPU 0 x kernel: [ 226 [ 229.214401] Modules linked in: ipv6 dm_multipath uinput nouveau snd_hda_codec_realtek snd_hda_intel ttm drm_kms_helper drm snd_hda_codec snd_hwdep snd_pcm snd_timer i2c_algo_bit isci snd libsas ioatdma mxm_wmi iTCO_wdt soundcore snd_page_alloc scsi_transport_sas iTCO_vendor_support wmi dca video i2c_i801 i2c_core [last unloaded: speedstep_lib] [ 229.214401] [ 229.214401] Pid: 5, comm: kworker/u:0 Not tainted 3.0.0-isci-11.7.29+ #30.353196] Buffer Intel Corporation Stoakley/Pearlcity Workstation [ 229.214401] RIP: 0010:[<ffffffffa00a58be>] I/O error on dev [<ffffffffa00a58be>] sci_request_completed_state_enter+0x50/0xafb [isci] [ 229.214401] RSP: 0018:ffff88014fc03d20 EFLAGS: 00010046 [ 229.214401] RAX: 0000000000000000 RBX: ffff88014741f000 RCX: 0000000000000000 [ 229.214401] RDX: ffffffffa00b2c90 RSI: 0000000000000017 RDI: ffff88014741f0a0 [ 229.214401] RBP: ffff88014fc03d90 R08: 0000000000000018 R09: 0000000000000000 [ 229.214401] R10: 0000000000000000 R11: ffffffff81a17d98 R12: 000000000000001d [ 229.214401] R13: ffff8801470f46c0 R14: 0000000000000000 R15: 0000000000008000 [ 229.214401] FS: 0000000000000000(0000) GS:ffff88014fc00000(0000) knlGS:0000000000000000 [ 229.214401] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 229.214401] CR2: 0000000000000228 CR3: 000000013ceaa000 CR4: 00000000000406f0 [ 229.214401] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 229.214401] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 229.214401] Process kworker/u:0 (pid: 5, threadinfo ffff880149714000, task ffff880149718000) [ 229.214401] Call Trace: [ 229.214401] <IRQ> [ 229.214401] [<ffffffffa00aa6ce>] sci_change_state+0x4a/0x4f [isci] [ 229.214401] [<ffffffffa00a4ca6>] sci_io_request_tc_completion+0x79c/0x7a0 [isci] [ 229.214401] [<ffffffffa00acf35>] sci_controller_process_completions+0x14f/0x396 [isci] [ 229.214401] [<ffffffffa00abbda>] ?

The currentsd[] array in hpsa_update_scsi_devices had room for 256 devices. The code was iterating over however many physical and logical devices plus an additional number of possible external MSA2XXX controllers, which together could potentially exceed 256. We increased the size of the currentsd array to 1024 + 1024 + 32 + 1 elements to reflect a reasonable maximum possible number of devices which might be encountered. We also don't just walk off the end of the array if the array controller reports more devices than we are prepared to handle, we just ignore the excessive devices. Signed-off-by:

During heavy I/O (CPU-affinity mode enabled) and CLI/Agent interactions, the driver would report periodic mailbox command timeout statuses. Within the CPU-affinity ISR handler, the driver should check the 'disable-msix-handshake' flag in deciding whether or not to clear HCCRX_CLR_RISC_INT. The mode is not specific to a dedicated queue, instead, applies to the current 'ha' context. Signed-off-by:

When SRR LS_ACC is dropped, the driver was not issuing ABTS for SRR when it times out. Since the target received SRR, it was able to send the XFER_RDY and the the original IO request completed successfully. In this condition ABTS was not sent during bnx2fc_srr_compl(). Fix this by first checking for ELS timeout and issue ABTS before checking if original IO request is complete. Signed-off-by:

The driver was setting the action to MPI2_CONFIG_ACTION_PAGE_READ_CURRENT, which only returns active volumes. In order to get info on inactive volumes, the driver needs to change the action to MPI2_RAID_PGAD_FORM_GET_NEXT_CONFIGNUM, and traverse each config till the iocstatus is MPI2_IOCSTATUS_CONFIG_INVALID_PAGE returned. Added a change in the driver to remove the instance of sas_device object when the driver returns "1" from the slave_configure callback.

[SCSI] mpt2sas: Fix for issue Port Reset taking long time(around 5 mins) to complete while issued during creating a volume This is due to the slave_configuration routine is getting called when host reset is active, and config page reads are failing, and driver attempts to added device with stale config data. To fix the issue, added error checking in slave_configure to check for configuration pages failing, and return "1" so the device is not configured. The config pages are failing if raid volume is configured while issuing a host reset, thus driver is reading stale data and proceeding to attempt to add. The fix is to return error so the volume is not configured. Signed-off-by:

This is due to driver reporting a device missing to the OS then the OS sending a SYNC_CACHE request to driver while the IO queues are locked due to host reset.

Fix for issue : While discovery is in progress, hot unplug and hot plug of enclosure connected to the controller card is causing system to hang. When a device is in the process of being detected at driver load time then if it is removed, the device that is no longer present will not be added to the list. So the code in _scsih_probe_sas() is rearranged as such so the devices that failed to be detected are not added to the list. Signed-off-by:

New feature Fast Load Support. (1)Asynchronous SCSI scanning: This will allow the drivers to scan for devices in parallel while other device drivers are loading at the same time. This will improve the amount of time it takes for the OS to load. (2) Reporting Devices while port enable is active: This feature will allow devices to be reported to OS immediately while port enable is active. The previous implementation waits for port enable to complete, and then report devices. This feature is only enabled on IT firmware configurations when there are no boot device configured in BIOS Configuration Utility, else the driver will wait till port enable completes reporting devices. For IR firmware, this feature is turned off. This feature is to address large SAS topologies (>100 drives) when the boot OS is using onboard SATA device, in other words, the boot devices is not connected to our controller. (3) Scanning for devices after diagnostic reset completes: A new routine _scsih_scan_start is added. This will scan the expander pages, IR pages, and sas device pages, then reporting new devices to SCSI Mid layer. It seems the driver is not supporting adding devices while diagnostic reset is active. Apparently this is due to the sanity checks on ioc->shost_recovery flag throughout the context of kernel work thread FIFO, and the mpt2sas_fw_work. Signed-off-by:
