KSMBD RACES AND DRM FIXES FLOOD RC2, VFS LAYERS NEED ATTENTION

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

The kernel team is stamping out use-after-free races in the SMB server while wrestling with a larger-than-usual batch of graphics and filesystem fixes across the stack.

The SMB3 server merged critical fixes [1] for several use-after-free races in durable handle reconnect and oplock handling, plus a significant performance win: removing delays up to 35 seconds when the inode oplock lock was held during lease break acknowledgements. This is the kind of fix that surfaces in production first. The DRM pull [2] is notably large for rc2, spanning xe, amdgpu, panthor, and a set of dma-fence robustness improvements including a NULL pointer dereference fix and a more resilient dedup array. VFS landed its own batch [3] with netfs corrections including double fput bugs, S_KERNEL_FILE clearing races, and page extraction underflows in iov_iter helpers that could have triggered on edge cases. XFS followed with buffer handling refactoring [4], simplifying error paths and fixing synchronous error handling in xfs_buf_submit. The ACPI fixes [5] are minor but notable for cleaning up decades of #ifdef __KERNEL__ cruft by aliasing safe_strncpy to strscpy_pad. This is rc2 noise, but the SMB and VFS layers are where you should spend your review cycles.
