KSMBD FIXES LAND AS BTRFS SQUOTA GETS PATCHED

By RepoJournal · Filed · About Linux · Composed from the cited sources · methodology

Linux 7.1-rc5 ships critical SMB server and filesystem fixes overnight, with ksmbd addressing security descriptor validation and btrfs closing gaps in quota tracking that could silently corrupt accounting.

The ksmbd server pull [1] lands three fixes that matter for production SMB deployments: SID validation in ACL inheritance prevents privilege escalation vectors, durable reconnect error handling fixes file lifetime issues, and tmpfile creation now correctly promotes deletion flags on close. Btrfs squota [2] gets a surgical batch addressing the quota invariant violations that made subvolume deletion risky, adding rescheduling points to prevent preemption hangs on PREEMPT_NONE kernels, and properly initializing extent tracking during squota enablement. Driver core [4] removes a subtle leak where software nodes stayed registered after platform device release, causing -EBUSY on subsequent registrations with the same node. I2C fixes [5] patch an smbus uninitialization bug and tegra mutex handling that could lose transfer errors, while LoongArch [3] reworks KASLR to prevent initrd overlap and fixes kprobes fatal error handling.
