This violates RFC 8881 section 6.4.1.3: "the ACL attribute is set as given". The issue occurs in nfsd_create_setattr(), which calls nfsd_attrs_valid() to determine whether to call nfsd_setattr(). However, nfsd_attrs_valid() checks only for iattr changes and security labels, but not POSIX ACLs. When only an ACL is present, the function returns false, nfsd_setattr() is skipped, and the POSIX ACL is never applied to the inode. Subsequently, when the client retrieves the ACL, the server finds no POSIX ACL on the inode and returns one generated from the file's mode bits rather than returning the originally-specified ACL.

[PATCH 0/4] drm: Revert and fix enable/disable sequence

by Tomi Valkeinen

Changing the enable/disable sequence in commit c9b1150a68d9 ("drm/atomic-helper: Re-order bridge chain pre-enable and post-disable") has caused regressions on multiple platforms: R-Car, MCDE, Rockchip. This is an alternate series to Linus' series: https://lore.kernel.org/all/20251202-mcde-drm-regression-thirdfix-v6-0-f1bf… This series first reverts the original commit and reverts a fix for mediatek which is no longer needed. It then exposes helper functions from DRM core, and finally implements the new sequence only in the tidss driver. There is one more fix in upstream for the original commit, commit 5d91394f2361 ("drm/exynos: fimd: Guard display clock control with runtime PM calls"), but I have not reverted that one as it looks like a valid patch in its own. I added Cc stable v6.17+ to all patches, but I didn't add Fixes tags, as I wasn't sure what should they point to. But I could perhaps add Fixes: <original commit> to all of these.

[PATCH 0/4] mm/damon/sysfs: free setup failures generated zombie sub-sub dirs

by SeongJae Park

Some DAMON sysfs directory setup functions generates its sub and sub-sub directories. For example, 'monitoring_attrs/' directory setup creates 'intervals/' and 'intervals/intervals_goal/' directories under 'monitoring_attrs/' directory. When such sub-sub directories are successfully made but followup setup is failed, the setup function should recursively clean up the subdirectories. However, such setup functions are only dereferencing sub directory reference counters. As a result, under certain setup failures, the sub-sub directories keep having non-zero reference counters. It means the directories cannot be removed like zombies, and the memory for the directories cannot be freed. The user impact of this issue is limited due to the following reasons. When the issue happens, the zombie directories are still taking the path. Hence attempts to generate the directories again will fail, without additional memory leak. This means the upper bound memory leak is limited. Nonetheless this also implies controlling DAMON with a feature that requires the setup-failed sysfs files will be impossible until the system reboots. Also, the setup operations are quite simple. The certain failures would hence only rarely happen, and are difficult to artificially trigger.

[PATCH] USB: OHCI/UHCI: Add soft dependencies on ehci_hcd

by Huacai Chen

Commit 9beeee6584b9aa4f ("USB: EHCI: log a warning if ehci-hcd is not loaded first") said that ehci-hcd should be loaded before ohci-hcd and uhci-hcd. However, commit 05c92da0c52494ca ("usb: ohci/uhci - add soft dependencies on ehci_pci") only makes ohci-pci/uhci-pci depend on ehci- pci, which is not enough and we may still see the warnings in boot log. So fix it by also making ohci-hcd/uhci-hcd depend on ehci-hcd.
