[PATCH] drbd: Fix atomicity violation in drbd_uuid_set_bm()

by Qiu-ji Chen

The violation of atomicity occurs when the drbd_uuid_set_bm function is executed simultaneously with modifying the value of device->ldev->md.uuid[UI_BITMAP]. Consider a scenario where, while device->ldev->md.uuid[UI_BITMAP] passes the validity check when its value is not zero, the value of device->ldev->md.uuid[UI_BITMAP] is written to zero. In this case, the check in drbd_uuid_set_bm might refer to the old value of device->ldev->md.uuid[UI_BITMAP] (before locking), which allows an invalid value to pass the validity check, resulting in inconsistency. To address this issue, it is recommended to include the data validity check within the locked section of the function. This modification ensures that the value of device->ldev->md.uuid[UI_BITMAP] does not change during the validation process, thereby maintaining its integrity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH 6.1] drm/amdkfd: Skip handle mapping SVM range with no GPU access

by Murad Masimov

From: Philip Yang <Philip.Yang(a)amd.com> commit 8c45b31909b730f9c7b146588e038f9c6553394d upstream. If the SVM range has no GPU access nor access-in-place attribute, validate and map to GPU should skip the range. Add NULL pointer check if find_first_bit(ctx->bitmap, MAX_GPU_INSTANCE) returns MAX_GPU_INSTANCE as gpuidx if ctx->bitmap is empty.

[PATCH] ALSA: hda/realtek: fix mute/micmute LED for HP mt645 G8

[PATCH RFC V5 1/1] ocfs2: reserve space for inline xattr before attaching reflink tree

by Gautham Ananthakrishna

One of our customers reported a crash and a corrupted ocfs2 filesystem. The crash was due to the detection of corruption. Upon troubleshooting, the fsck -fn output showed the below corruption [EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record, but fsck believes the largest valid value is 227. Clamp the next record value? n The stat output from the debugfs.ocfs2 showed the following corruption where the "Next Free Rec:" had overshot the "Count:" in the root metadata block. Inode: 33080590 Mode: 0640 Generation: 2619713622 (0x9c25a856) FS Generation: 904309833 (0x35e6ac49) CRC32: 00000000 ECC: 0000 Type: Regular Attr: 0x0 Flags: Valid Dynamic Features: (0x16) HasXattr InlineXattr Refcounted Extended Attributes Block: 0 Extended Attributes Inline Size: 256 User: 0 (root) Group: 0 (root) Size: 281320357888 Links: 1 Clusters: 141738 ctime: 0x66911b56 0x316edcb8 -- Fri Jul 12 06:02:30.829349048 2024 atime: 0x66911d6b 0x7f7a28d -- Fri Jul 12 06:11:23.133669517 2024 mtime: 0x66911b56 0x12ed75d7 -- Fri Jul 12 06:02:30.317552087 2024 dtime: 0x0 -- Wed Dec 31 17:00:00 1969 Refcount Block: 2777346 Last Extblk: 2886943 Orphan Slot: 0 Sub Alloc Slot: 0 Sub Alloc Bit: 14 Tree Depth: 1 Count: 227 Next Free Rec: 230 ## Offset Clusters Block# 0 0 2310 2776351 1 2310 2139 2777375 2 4449 1221 2778399 3 5670 731 2779423 4 6401 566 2780447 ....... .... ....... ....... .... ....... The issue was in the reflink workfow while reserving space for inline xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the time this function is called the reflink tree is already recreated at the destination inode from the source inode. At this point, this function reserves space for inline xattrs at the destination inode without even checking if there is space at the root metadata block. It simply reduces the l_count from 243 to 227 thereby making space of 256 bytes for inline xattr whereas the inode already has extents beyond this index (in this case upto 230), thereby causing corruption. The fix for this is to reserve space for inline metadata at the destination inode before the reflink tree gets recreated. The customer has verified the fix.

[PATCH AUTOSEL 4.19] x86/hyperv: Set X86_FEATURE_TSC_KNOWN_FREQ when Hyper-V provides frequency

by Sasha Levin

From: Michael Kelley <mhklinux(a)outlook.com> [ Upstream commit 8fcc514809de41153b43ccbe1a0cdf7f72b78e7e ] A Linux guest on Hyper-V gets the TSC frequency from a synthetic MSR, if available. In this case, set X86_FEATURE_TSC_KNOWN_FREQ so that Linux doesn't unnecessarily do refined TSC calibration when setting up the TSC clocksource. With this change, a message such as this is no longer output during boot when the TSC is used as the clocksource: [ 1.115141] tsc: Refined TSC clocksource calibration: 2918.408 MHz Furthermore, the guest and host will have exactly the same view of the TSC frequency, which is important for features such as the TSC deadline timer that are emulated by the Hyper-V host.
