[REGRESSION] 6.7.1: md: raid5 hang and unresponsive system; successfully bisected

by Dan Moulding

After upgrading from 6.7.0 to 6.7.1 a couple of my systems with md RAID-5 arrays started experiencing hangs. It starts with some processes which write to the array getting stuck. The whole system eventually becomes unresponsive and unclean shutdown must be performed (poweroff and reboot don't work). While trying to diagnose the issue, I noticed that the md0_raid5 kernel thread consumes 100% CPU after the issue occurs. No relevant warnings or errors were found in dmesg. On 6.7.1, I can reproduce the issue somewhat reliably by copying a large amount of data to the array. I am unable to reproduce the issue at all on 6.7.0. The bisection was a bit difficult since I don't have a 100% reliable method to reproduce the problem, but with some perseverence I eventually managed to whittle it down to commit 0de40f76d567 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"). After reverting that commit (i.e. reapplying the reverted commit) on top of 6.7.1 I can no longer reproduce the problem at all. Some details that might be relevant: - Both systems are running MD RAID-5 with a journal device. - mdadm in monitor mode is always running on both systems. - Both systems were previously running 6.7.0 and earlier just fine. - The older of the two systems has been running a raid5 array without incident for many years (kernel going back to at least 5.1) -- this is the first raid5 issue it has encountered. Please let me know if there is any other helpful information that I might be able to provide. -- Dan #regzbot introduced: 0de40f76d567133b871cd6ad46bb87afbce46983

[PATCH] perf/x86/intel/uncore: Fix the bits of the CHA extended umask for SPR

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> The perf stat errors out with UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL event. $perf stat -e uncore_cha_55/event=0x35,umask=0x10c0008101/ -a -- ls event syntax error: '..0x35,umask=0x10c0008101/' \___ Bad event or PMU The definition of the CHA umask is config:8-15,32-55, which is 32bit. However, the umask of the event is bigger than 32bit. This is an error in the original uncore spec. Add a new umask_ext5 for the new CHA umask range.

I/O errors while writing to external Transcend XS-2000 4TB SSD

by Martin Steigerwald

Hi! This is not exactly a regression, as I am not aware of a prior working state, but kernel documentation advises me to CC regressions list anyway¹. I am trying to put data on an external Kingston XS-2000 4 TB SSD using self-compiled Linux 6.7.4 kernel and encrypted BCacheFS. I do not think BCacheFS has any part in the errors I see, but if you disagree feel free to CC the BCacheFS mailing list as you reply. I am using a ThinkPad T14 AMD Gen 1 with AMD Ryzen 7 PRO 4750U and 32 GiB of RAM. I connected the SSD onto USB-C port directly with the ThinkPad. lsusb lists it as: Bus 007 Device 004: ID 0951:176b Kingston Technology XS2000 The SSD is detected as follows: [20303.913644] usb 7-1: new SuperSpeed Plus Gen 2x1 USB device number 9 using xhci_hcd [20303.926616] usb 7-1: New USB device found, idVendor=0951, idProduct=176b, bcdDevice= 1.00 [20303.926633] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [20303.926641] usb 7-1: Product: XS2000 [20303.926647] usb 7-1: Manufacturer: Kingston [20303.926652] usb 7-1: SerialNumber: […] [20303.929078] scsi host0: uas [20303.983859] scsi 0:0:0:0: Direct-Access Kingston XS2000 1000 PQ: 0 ANSI: 6 [20303.984426] sd 0:0:0:0: Attached scsi generic sg0 type 0 [20303.985197] sd 0:0:0:0: [sda] 8001573552 512-byte logical blocks: (4.10 TB/3.73 TiB) [20303.985331] sd 0:0:0:0: [sda] Write Protect is off [20303.985341] sd 0:0:0:0: [sda] Mode Sense: 43 00 00 00 [20303.985579] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [20303.989516] sda: sda1 [20303.989611] sd 0:0:0:0: [sda] Attached SCSI disk BCacheFS is mounted as follows – but I suspect BCacheFS is not involved in those errors anyway: [20310.437864] bcachefs (sda1): mounting version 1.3: rebalance_work opts=metadata_checksum=xxhash,data_checksum=xxhash,compression=lz4 [20310.437895] bcachefs (sda1): recovering from clean shutdown, journal seq 5094 [20310.450813] bcachefs (sda1): alloc_read... done [20310.450851] bcachefs (sda1): stripes_read... done [20310.450855] bcachefs (sda1): snapshots_read... done [20310.470815] bcachefs (sda1): journal_replay... done [20310.470824] bcachefs (sda1): resume_logged_ops... done [20310.470835] bcachefs (sda1): going read-write During rsync'ing about 1,4 TB of data after eventually a hour I got things like this: [33963.462694] sd 0:0:0:0: [sda] tag#10 uas_zap_pending 0 uas-tag 1 inflight: CMD [33963.462708] sd 0:0:0:0: [sda] tag#10 CDB: Write(16) 8a 00 00 00 00 00 82 c1 bc 00 00 00 04 00 00 00 [33963.462718] sd 0:0:0:0: [sda] tag#11 uas_zap_pending 0 uas-tag 2 inflight: CMD [33963.462725] sd 0:0:0:0: [sda] tag#11 CDB: Write(16) 8a 00 00 00 00 00 82 c1 c8 00 00 00 04 00 00 00 [33963.462733] sd 0:0:0:0: [sda] tag#15 uas_zap_pending 0 uas-tag 3 inflight: CMD [33963.462740] sd 0:0:0:0: [sda] tag#15 CDB: Write(16) 8a 00 00 00 00 00 82 c1 d2 4c 00 00 01 2f 00 00 [33963.462748] sd 0:0:0:0: [sda] tag#12 uas_zap_pending 0 uas-tag 4 inflight: CMD [33963.462754] sd 0:0:0:0: [sda] tag#12 CDB: Write(16) 8a 00 00 00 00 00 82 c1 d0 00 00 00 02 4c 00 00 [33963.462762] sd 0:0:0:0: [sda] tag#13 uas_zap_pending 0 uas-tag 5 inflight: CMD [33963.462769] sd 0:0:0:0: [sda] tag#13 CDB: Write(16) 8a 00 00 00 00 00 82 c1 d4 00 00 00 00 ff 00 00 [33963.462777] sd 0:0:0:0: [sda] tag#14 uas_zap_pending 0 uas-tag 6 inflight: CMD [33963.462783] sd 0:0:0:0: [sda] tag#14 CDB: Write(16) 8a 00 00 00 00 00 82 c1 ce 00 00 00 00 cc 00 00 [33963.576991] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 9 using xhci_hcd [33963.590793] scsi host0: uas_eh_device_reset_handler success [33963.592857] sd 0:0:0:0: [sda] tag#10 timing out command, waited 180s [33963.592872] sd 0:0:0:0: [sda] tag#10 FAILED Result: hostbyte=DID_RESET driverbyte=DRIVER_OK cmd_age=182s [33963.592881] sd 0:0:0:0: [sda] tag#10 CDB: Write(16) 8a 00 00 00 00 00 82 c1 bc 00 00 00 04 00 00 00 [33963.592886] I/O error, dev sda, sector 2193734656 op 0x1:(WRITE) flags 0x104000 phys_seg 773 prio class 2 [33963.592898] bcachefs (sda1 inum 1073761281 offset 265216): data write error: I/O [33963.592925] bcachefs (sda1 inum 1073761281 offset 467456): data write error: I/O [33963.592933] bcachefs (sda1 inum 1073761281 offset 470016): data write error: I/O [33963.592939] bcachefs (sda1 inum 1073761281 offset 471552): data write error: I/O [33963.592949] bcachefs (sda1 inum 1073761281 offset 514560): data write error: I/O [33963.592956] bcachefs (sda1 inum 1073761281 offset 517120): data write error: I/O [33963.592963] bcachefs (sda1 inum 1073761281 offset 519168): data write error: I/O [33963.592969] bcachefs (sda1 inum 1073761281 offset 521728): data write error: I/O [33963.592976] bcachefs (sda1 inum 1073761281 offset 523776): data write error: I/O [33963.592983] bcachefs (sda1 inum 1073761281 offset 526336): data write error: I/O The rsync completed but I did not trust the result, even tough "bcachefs fsck" told me the filesystem structure is okay. Thus I reran rsync with option "-c" for checksumming. After a long time with data that did match, it started to transfer a file again which should not happen if data would have been identical. As it ran into I/O errors again, I stopped the rsync process. I looked for that UAS error message and according to the article² I found I disabled UAS as follows: % cat /etc/modprobe.d/disable-uas.conf # Does not work with external SSD Transcend XS2000 4TB options usb-storage quirks=0951:176b:u The quirk was applied as I reconnected the devices after unloading both usb-storage and uas modules: [ 55.871301] usb 7-1: UAS is ignored for this device, using usb-storage instead [ 55.871310] usb-storage 7-1:1.0: USB Mass Storage device detected [ 55.871559] usb-storage 7-1:1.0: Quirks match for vid 0951 pid 176b: 800000 I recreated the BCacheFS filesystem and tried again. This time it did not take more than 10 minutes for the first I/O error to appear. Unless with UAS it made rsync stop with an I/O error immediately. Before that there were several USB resets. Here is the excerpt from dmesg: [ 795.768306] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 932.976677] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 963.189438] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 1000.057333] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 1036.917137] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 1073.782876] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 1110.647786] usb 7-1: reset SuperSpeed Plus Gen 2x1 USB device number 4 using xhci_hcd [ 1117.163693] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ABORT driverbyte=DRIVER_OK cmd_age=214s [ 1117.163718] sd 0:0:0:0: [sda] tag#0 CDB: Write(16) 8a 00 00 00 00 00 02 72 20 00 00 00 08 00 00 00 [ 1117.163725] I/O error, dev sda, sector 41033728 op 0x1:(WRITE) flags 0x104000 phys_seg 1551 prio class 2 [ 1117.163739] bcachefs (sda1 inum 1879048481 offset 2572800): data write error: I/O [ 1117.163763] bcachefs (sda1 inum 1879048481 offset 2576384): data write error: I/O [ 1117.163771] bcachefs (sda1 inum 1879048481 offset 2578432): data write error: I/O [ 1117.163779] bcachefs (sda1 inum 1879048481 offset 2580480): data write error: I/O [ 1117.163786] bcachefs (sda1 inum 1879048481 offset 2582528): data write error: I/O [ 1117.163794] bcachefs (sda1 inum 1879048481 offset 2584576): data write error: I/O [ 1117.163803] bcachefs (sda1 inum 1879048481 offset 2586624): data write error: I/O [ 1117.163811] bcachefs (sda1 inum 1879048481 offset 2588672): data write error: I/O [ 1117.163818] bcachefs (sda1 inum 1879048481 offset 2590720): data write error: I/O [ 1117.163824] bcachefs (sda1 inum 1879048481 offset 2592768): data write error: I/O So even without UAS the device does not seem to like to write data on Linux. Next steps may involve looking for a firmware update for the external SSD as well as trying to obtain its SMART status. So far I did not succeed in finding the right options for smartctl. In case there is enough evidence that the device is defective I'd try to RMA it. I will keep a copy of kernel log and I could do some further tests as time permits. So let me know whether you need anything else, but for now the mail is long enough as it is.

We can trigger a slab-out-of-bounds with the following commands: mkfs.ext4 -F /dev/$disk 10G mount /dev/$disk /tmp/test echo 2147483647 > /sys/fs/ext4/$disk/mb_group_prealloc echo test > /tmp/test/file && sync ================================================================== BUG: KASAN: slab-out-of-bounds in ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] Read of size 8 at addr ffff888121b9d0f0 by task kworker/u2:0/11 CPU: 0 PID: 11 Comm: kworker/u2:0 Tainted: GL 6.7.0-next-20240118 #521 Call Trace: dump_stack_lvl+0x2c/0x50 kasan_report+0xb6/0xf0 ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] ext4_mb_regular_allocator+0x19e9/0x2370 [ext4] ext4_mb_new_blocks+0x88a/0x1370 [ext4] ext4_ext_map_blocks+0x14f7/0x2390 [ext4] ext4_map_blocks+0x569/0xea0 [ext4] ext4_do_writepages+0x10f6/0x1bc0 [ext4] [...] ================================================================== The flow of issue triggering is as follows: // Set s_mb_group_prealloc to 2147483647 via sysfs ext4_mb_new_blocks ext4_mb_normalize_request ext4_mb_normalize_group_request ac->ac_g_ex.fe_len = EXT4_SB(sb)->s_mb_group_prealloc ext4_mb_regular_allocator ext4_mb_choose_next_group ext4_mb_choose_next_group_best_avail mb_avg_fragment_size_order order = fls(len) - 2 = 29 ext4_mb_find_good_group_avg_frag_lists frag_list = &sbi->s_mb_avg_fragment_size[order] if (list_empty(frag_list)) // Trigger SOOB! At 4k block size, the length of the s_mb_avg_fragment_size list is 14, but an oversized s_mb_group_prealloc is set, causing slab-out-of-bounds to be triggered by an attempt to access an element at index 29. Add a new attr_id attr_clusters_in_group with values in the range [0, sbi->s_clusters_per_group] and declare mb_group_prealloc as that type to fix the issue. In addition avoid returning an order from mb_avg_fragment_size_order() greater than MB_NUM_ORDERS(sb) and reduce some useless loops.
