The following sequence of event leads to NVME port disappearing: - device port shut - nvme_fc_unregister_remoteport - device port online - remote port delete completes - relogin is scheduled - "post gidpn" message appears due to rscn generation # mismatch In short, if a device comes back online sooner than an unregister completion, a mismatch in rscn generation number occurs, which is not handled correctly during device relogin. Fix this by starting with a redo of GNL. When ql2xextended_error_logging is enabled, the re-plugged device's discovery stops with the following messages printed: --8<-- qla2xxx [0000:41:00.0]-480d:3: Relogin scheduled. qla2xxx [0000:41:00.0]-4800:3: DPC handler sleeping. qla2xxx [0000:41:00.0]-2902:3: qla24xx_handle_relogin_event 21:00:00:24:ff:17:9e:91 DS 0 LS 7 P 0 del 2 cnfl (null) rscn 1|2 login 1|2 fl 1 qla2xxx [0000:41:00.0]-28e9:3: qla24xx_handle_relogin_event 1666 21:00:00:24:ff:17:9e:91 post gidpn qla2xxx [0000:41:00.0]-480e:3: Relogin end. --8<-- Signed-off-by:Arun Easi <aeasi@marvell.com> Signed-off-by:

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: -

We can request task management IOCTL command(MPI2_FUNCTION_SCSI_TASK_MGMT) to /dev/mpt3ctl. If the given task_type is either abort task or query task, it may need a field named "Initiator Port Transfer Tag to Manage" in the IU. Current code does not support to check target IPTT tag from the tm_request. This patch introduces to check TaskMID given from the userspace as a target tag. We have a rule of relationship between (struct request *req->tag) and smid in mpt3sas_base.c: 3318 u16 3319 mpt3sas_base_get_smid_scsiio(struct MPT3SAS_ADAPTER *ioc, u8 cb_idx, 3320 struct scsi_cmnd *scmd) 3321 { 3322 struct scsiio_tracker *request = scsi_cmd_priv(scmd); 3323 unsigned int tag = scmd->request->tag; 3324 u16 smid; 3325 3326 smid = tag + 1; So if we want to abort a request tagged #X, then we can pass (X + 1) to this IOCTL handler. Otherwise, user space just can pass 0 TaskMID to abort the first outstanding smid which is legacy behaviour.

There is a copy and paste bug here. It uses EVENT_TRIGGERS size instead of SCSI_TRIGGERS size but fortunately both size are 84 bytes so it doesn't affect runtime. These days the preferred style is to just say sizeof(object) instead of sizeof(type) so I have updated the function to the latest style as well. Signed-off-by:

This patch is to change msleep() to usleep_range() based on Documentation/timers/timers-howto.txt. It suggests using usleep_range() for small msec(1ms - 20ms) since msleep() will often sleep longer than desired value. After changing, booting time will be 5ms-10ms faster than before. I tested this change on two different platforms, one has 5ms faster, another one is about 10ms. I think this is different on different platform. Actually, from UFS host side, 1ms-5ms delay is already sufficient for its initialization of the local UIC layer. Fixes: 7a3e97b0 ([SCSI] ufshcd: UFS Host controller driver) Signed-off-by:

Adding the command and kicking the virtqueue so far was done one after another. Make the kick optional, so that we can take into account SCMD_LAST. We also need a commit_rqs callback to kick the device if blk-mq aborts the submission before the last request is reached. Suggested-by:

This allows a list of requests to be issued, with the LLD only writing the hardware doorbell when necessary, after the last request was prepared. This is more efficient if we have lists of requests to issue, particularly on virtualized hardware, where writing the doorbell is more expensive than on real hardware. The use case for this is plugged IO, where blk-mq flushes a batch of requests all at once. The API is the same as for blk-mq, just with blk-mq concepts tweaked to fit the SCSI subsystem API: the "last" flag in blk_mq_queue_data becomes a flag in scsi_cmnd, while the queue_num in the commit_rqs callback is extracted from the hctx and passed as a parameter. The only complication is that blk-mq uses different plugging heuristics depending on whether commit_rqs is present or not. So we have two different sets of blk_mq_ops and pick one depending on whether the scsi_host template uses commit_rqs or not. Signed-off-by:
