Vulnerability Title
md/raid0, raid10: Don't set discard sectors for request queue
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: md/raid0, raid10: Don't set discard sectors for request queue It should use disk_stack_limits to get a proper max_discard_sectors rather than setting a value by stack drivers. And there is a bug. If all member disks are rotational devices, raid0/raid10 set max_discard_sectors. So the member devices are not ssd/nvme, but raid0/raid10 export the wrong value. It reports warning messages in function __blkdev_issue_discard when mkfs.xfs like this: [ 4616.022599] ------------[ cut here ]------------ [ 4616.027779] WARNING: CPU: 4 PID: 99634 at block/blk-lib.c:50 __blkdev_issue_discard+0x16a/0x1a0 [ 4616.140663] RIP: 0010:__blkdev_issue_discard+0x16a/0x1a0 [ 4616.146601] Code: 24 4c 89 20 31 c0 e9 fe fe ff ff c1 e8 09 8d 48 ff 4c 89 f0 4c 09 e8 48 85 c1 0f 84 55 ff ff ff b8 ea ff ff ff e9 df fe ff ff <0f> 0b 48 8d 74 24 08 e8 ea d6 00 00 48 c7 c6 20 1e 89 ab 48 c7 c7 [ 4616.167567] RSP: 0018:ffffaab88cbffca8 EFLAGS: 00010246 [ 4616.173406] RAX: ffff9ba1f9e44678 RBX: 0000000000000000 RCX: ffff9ba1c9792080 [ 4616.181376] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff9ba1c9792080 [ 4616.189345] RBP: 0000000000000cc0 R08: ffffaab88cbffd10 R09: 0000000000000000 [ 4616.197317] R10: 0000000000000012 R11: 0000000000000000 R12: 0000000000000000 [ 4616.205288] R13: 0000000000400000 R14: 0000000000000cc0 R15: ffff9ba1c9792080 [ 4616.213259] FS: 00007f9a5534e980(0000) GS:ffff9ba1b7c80000(0000) knlGS:0000000000000000 [ 4616.222298] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4616.228719] CR2: 000055a390a4c518 CR3: 0000000123e40006 CR4: 00000000001706e0 [ 4616.236689] Call Trace: [ 4616.239428] blkdev_issue_discard+0x52/0xb0 [ 4616.244108] blkdev_common_ioctl+0x43c/0xa00 [ 4616.248883] blkdev_ioctl+0x116/0x280 [ 4616.252977] __x64_sys_ioctl+0x8a/0xc0 [ 4616.257163] do_syscall_64+0x5c/0x90 [ 4616.261164] ? handle_mm_fault+0xc5/0x2a0 [ 4616.265652] ? do_user_addr_fault+0x1d8/0x690 [ 4616.270527] ? do_syscall_64+0x69/0x90 [ 4616.274717] ? exc_page_fault+0x62/0x150 [ 4616.279097] entry_SYSCALL_64_after_hwframe+0x63/0xcd [ 4616.284748] RIP: 0033:0x7f9a55398c6b
