Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: qla2xxx: During vport delete send async logout explicitly<br /> <br /> During vport delete, it is observed that during unload we hit a crash<br /> because of stale entries in outstanding command array. For all these stale<br /> I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but<br /> I/Os could not complete while vport delete is in process of deleting.<br /> <br /> BUG: kernel NULL pointer dereference, address: 000000000000001c<br /> #PF: supervisor read access in kernel mode<br /> #PF: error_code(0x0000) - not-present page<br /> PGD 0 P4D 0<br /> Oops: 0000 [#1] PREEMPT SMP NOPTI<br /> Workqueue: qla2xxx_wq qla_do_work [qla2xxx]<br /> RIP: 0010:dma_direct_unmap_sg+0x51/0x1e0<br /> RSP: 0018:ffffa1e1e150fc68 EFLAGS: 00010046<br /> RAX: 0000000000000000 RBX: 0000000000000021 RCX: 0000000000000001<br /> RDX: 0000000000000021 RSI: 0000000000000000 RDI: ffff8ce208a7a0d0<br /> RBP: ffff8ce208a7a0d0 R08: 0000000000000000 R09: ffff8ce378aac9c8<br /> R10: ffff8ce378aac8a0 R11: ffffa1e1e150f9d8 R12: 0000000000000000<br /> R13: 0000000000000000 R14: ffff8ce378aac9c8 R15: 0000000000000000<br /> FS: 0000000000000000(0000) GS:ffff8d217f000000(0000) knlGS:0000000000000000<br /> CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033<br /> CR2: 000000000000001c CR3: 0000002089acc000 CR4: 0000000000350ee0<br /> Call Trace:<br /> <br /> qla2xxx_qpair_sp_free_dma+0x417/0x4e0<br /> ? qla2xxx_qpair_sp_compl+0x10d/0x1a0<br /> ? qla2x00_status_entry+0x768/0x2830<br /> ? newidle_balance+0x2f0/0x430<br /> ? dequeue_entity+0x100/0x3c0<br /> ? qla24xx_process_response_queue+0x6a1/0x19e0<br /> ? __schedule+0x2d5/0x1140<br /> ? qla_do_work+0x47/0x60<br /> ? process_one_work+0x267/0x440<br /> ? process_one_work+0x440/0x440<br /> ? worker_thread+0x2d/0x3d0<br /> ? process_one_work+0x440/0x440<br /> ? kthread+0x156/0x180<br /> ? set_kthread_struct+0x50/0x50<br /> ? ret_from_fork+0x22/0x30<br /> <br /> <br /> Send out async logout explicitly for all the ports during vport delete.
