Description

In the Linux kernel, the following vulnerability has been resolved:\nscsi: smartpqi: Fix disable_managed_interrupts\nCorrect blk-mq registration issue with module parameter\ndisable_managed_interrupts enabled.\nWhen we turn off the default PCI_IRQ_AFFINITY flag, the driver needs to\nregister with blk-mq using blk_mq_map_queues(). The driver is currently\ncalling blk_mq_pci_map_queues() which results in a stack trace and possibly\nundefined behavior.\nStack Trace:\n[ 7.860089] scsi host2: smartpqi\n[ 7.871934] WARNING: CPU: 0 PID: 238 at block/blk-mq-pci.c:52 blk_mq_pci_map_queues+0xca/0xd0\n[ 7.889231] Modules linked in: sd_mod t10_pi sg uas smartpqi(+) crc32c_intel scsi_transport_sas usb_storage dm_mirror dm_region_hash dm_log dm_mod ipmi_devintf ipmi_msghandler fuse\n[ 7.924755] CPU: 0 PID: 238 Comm: kworker/0:3 Not tainted 4.18.0-372.88.1.el8_6_smartpqi_test.x86_64 #1\n[ 7.944336] Hardware name: HPE ProLiant DL380 Gen10/ProLiant DL380 Gen10, BIOS U30 03/08/2022\n[ 7.963026] Workqueue: events work_for_cpu_fn\n[ 7.978275] RIP: 0010:blk_mq_pci_map_queues+0xca/0xd0\n[ 7.978278] Code: 48 89 de 89 c7 e8 f6 0f 4f 00 3b 05 c4 b7 8e 01 72 e1 5b 31 c0 5d 41 5c 41 5d 41 5e 41 5f e9 7d df 73 00 31 c0 e9 76 df 73 00 <0f> 0b eb bc 90 90 0f 1f 44 00 00 41 57 49 89 ff 41 56 41 55 41 54\n[ 7.978280] RSP: 0018:ffffa95fc3707d50 EFLAGS: 00010216\n[ 7.978283] RAX: 00000000ffffffff RBX: 0000000000000000 RCX: 0000000000000010\n[ 7.978284] RDX: 0000000000000004 RSI: 0000000000000000 RDI: ffff9190c32d4310\n[ 7.978286] RBP: 0000000000000000 R08: ffffa95fc3707d38 R09: ffff91929b81ac00\n[ 7.978287] R10: 0000000000000001 R11: ffffa95fc3707ac0 R12: 0000000000000000\n[ 7.978288] R13: ffff9190c32d4000 R14: 00000000ffffffff R15: ffff9190c4c950a8\n[ 7.978290] FS: 0000000000000000(0000) GS:ffff9193efc00000(0000) knlGS:0000000000000000\n[ 7.978292] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 8.172814] CR2: 000055d11166c000 CR3: 00000002dae10002 CR4: 00000000007706f0\n[ 8.172816] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[ 8.172817] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[ 8.172818] PKRU: 55555554\n[ 8.172819] Call Trace:\n[ 8.172823] blk_mq_alloc_tag_set+0x12e/0x310\n[ 8.264339] scsi_add_host_with_dma.cold.9+0x30/0x245\n[ 8.279302] pqi_ctrl_init+0xacf/0xc8e [smartpqi]\n[ 8.294085] ? pqi_pci_probe+0x480/0x4c8 [smartpqi]\n[ 8.309015] pqi_pci_probe+0x480/0x4c8 [smartpqi]\n[ 8.323286] local_pci_probe+0x42/0x80\n[ 8.337855] work_for_cpu_fn+0x16/0x20\n[ 8.351193] process_one_work+0x1a7/0x360\n[ 8.364462] ? create_worker+0x1a0/0x1a0\n[ 8.379252] worker_thread+0x1ce/0x390\n[ 8.392623] ? create_worker+0x1a0/0x1a0\n[ 8.406295] kthread+0x10a/0x120\n[ 8.418428] ? set_kthread_struct+0x50/0x50\n[ 8.431532] ret_from_fork+0x1f/0x40\n[ 8.444137] ---[ end trace 1bf0173d39354506 ]---
