SMB FIXES AND FUSE OVERHAUL LAND IN 7.2-RC1

By RepoJournal · Filed 06:02 UTC on June 19, 2026 · About Linux

Linux 7.2-rc1 merges critical SMB client and server patches alongside a major FUSE refactor that separates transport and filesystem layers for the first time.

Steve French's SMB client updates [1] hit the tree with races in cifsd thread creation patched, a potential out-of-bounds read in security descriptor parsing closed, and cached directory entries fixed on unlink/rmdir/rename. The corresponding server-side merge [2] addresses use-after-free and out-of-bounds issues while adding SMB compression support both at rest and over the wire, a significant capability upgrade for file servers. Fuse gets its most ambitious restructure in years [3], separating transport and filesystem layers, backporting bug fixes from the 6.x era, and adding io-uring and passthrough subsystems with dedicated maintainers. AHCI driver updates [4] now fail to probe if BAR size is undersized for the configured port count, catching firmware misconfigurations before they cause data loss. RDMA subsystem [5] pulls in extensive AI-driven bug fixes across mlx5, hns, rxe, and other drivers, tackling overflow arithmetic, races, and error path leaks.

Action items

→ Test SMB compression with workloads targeting ksmbd; verify cifsd thread behavior under load torvalds/linux [plan]
→ Validate AHCI driver initialization on hardware with undersized BARs before production rollout torvalds/linux [plan]
→ Review FUSE transport/fs separation impact on custom FUSE daemon implementations torvalds/linux [monitor]
