2025-11-07thunderbolt: Replace use of system_wq with system_percpu_wqMarco Crivellari
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") Replace system_wq with system_percpu_wq, keeping the old behavior. The old wq (system_wq) will be kept for a few release cycles.

2025-09-23thunderbolt: Fix use-after-free in tb_dp_dprx_workDuoming Zhou
The original code relies on cancel_delayed_work() in tb_dp_dprx_stop(), which does not ensure that the delayed work item tunnel->dprx_work has fully completed if it was already running. This leads to use-after-free scenarios where tb_tunnel is deallocated by tb_tunnel_put(), while tunnel->dprx_work remains active and attempts to dereference tb_tunnel in tb_dp_dprx_work(). A typical race condition is illustrated below: CPU 0 | CPU 1 tb_dp_tunnel_active() | tb_deactivate_and_free_tunnel()| tb_dp_dprx_start() tb_tunnel_deactivate() | queue_delayed_work() tb_dp_activate() | tb_dp_dprx_stop() | tb_dp_dprx_work() //delayed worker cancel_delayed_work() | tb_tunnel_put(tunnel); | | tunnel = container_of(...); //UAF | tunnel-> //UAF Replacing cancel_delayed_work() with cancel_delayed_work_sync() is not feasible as it would introduce a deadlock: both tb_dp_dprx_work() and the cleanup path acquire tb->lock, and cancel_delayed_work_sync() would wait indefinitely for the work item that cannot proceed. Instead, implement proper reference counting: - If cancel_delayed_work() returns true (work is pending), we release the reference in the stop function. - If it returns false (work is executing or already completed), the reference is released in delayed work function itself. This ensures the tb_tunnel remains valid during work item execution while preventing memory leaks. This bug was found by static analysis.

2025-08-14thunderbolt: Use is_pciehp instead of is_hotplug_bridgeLukas Wunner
The thunderbolt driver sets up device link dependencies from hotplug ports to the Host Router (aka Native Host Interface, NHI). When resuming from system sleep, this allows the Host Router to re-establish tunnels to attached Thunderbolt devices before the hotplug ports resume. To identify the hotplug ports, the driver utilizes the is_hotplug_bridge flag which also encompasses ACPI slots handled by the ACPI hotplug driver. Thunderbolt hotplug ports are always Hot-Plug Capable PCIe ports, so it is more apt to identify them with the is_pciehp flag. Similarly, hotplug ports on older Thunderbolt controllers have broken MSI support and are quirked to use legacy INTx interrupts instead. The quirk identifies them with is_hotplug_bridge, even though all affected ports are also matched by is_pciehp. So use is_pciehp here as well.

2025-08-11thunderbolt: Use HMAC-SHA256 library instead of crypto_shashEric Biggers
Use the hmac_sha256_usingrawkey() library function instead of the "hmac(sha256)" crypto_shash. This is simpler and faster. As a cleanup, change the input data parameters from "challenge, sizeof(hmac)" to "challenge, sizeof(challenge)", so that the size is being taken of the correct buffer. This is not a functional change, since it happens that sizeof(hmac) == sizeof(challenge). Replace the selection of CRYPTO and CRYPTO_HASH with CRYPTO_LIB_SHA256 and CRYPTO_LIB_UTILS. The latter is needed for crypto_memneq() which was previously being pulled in via CRYPTO.
