2026-04-21tpm: avoid -Wunused-but-set-variableArnd Bergmann
Outside of the EFI tpm code, the TPM_MEMREMAP()/TPM_MEMUNMAP functions are defined as trivial macros, leading to the mapping_size variable ending up unused: In file included from drivers/char/tpm/tpm-sysfs.c:16: In file included from drivers/char/tpm/tpm.h:28: include/linux/tpm_eventlog.h:167:6: error: variable 'mapping_size' set but not used [-Werror,-Wunused-but-set-variable] 167 | int mapping_size; Turn the stubs into inline functions to avoid this warning.

2026-04-21tpm: Use kfree_sensitive() to free auth session in tpm_dev_release()Gunnar Kudrjavets
tpm_dev_release() uses plain kfree() to free chip->auth, which contains sensitive cryptographic material including HMAC session keys, nonces, and passphrase data (struct tpm2_auth). Every other code path that frees this structure uses kfree_sensitive() to zero the memory before releasing it: both tpm2_end_auth_session() and tpm_buf_check_hmac_response() do so. The tpm_dev_release() path is the only one that does not, leaving key material in freed slab memory until it is eventually overwritten. Use kfree_sensitive() for consistency with the rest of the driver and to ensure session keys are scrubbed during device teardown.

2026-04-21tpm2-sessions: Fix missing tpm_buf_destroy() in tpm2_read_public()Gunnar Kudrjavets
tpm2_read_public() calls tpm_buf_init() but fails to call tpm_buf_destroy() on two exit paths, leaking a page allocation: 1. When name_size() returns an error (unrecognized hash algorithm), the function returns directly without destroying the buffer. 2. On the success path, the buffer is never destroyed before returning. All other error paths in the function correctly call tpm_buf_destroy() before returning. Fix both by adding the missing tpm_buf_destroy() calls.

2026-04-21tpm: Fix auth session leak in tpm2_get_random() error pathGunnar Kudrjavets
When tpm_buf_fill_hmac_session() fails inside the do-while loop in tpm2_get_random(), the function returns directly after destroying the buffer, without ending the auth session via tpm2_end_auth_session(). This leaks the TPM auth session resource. All other error paths within the loop correctly reach the 'out' label which calls both tpm_buf_destroy() and tpm2_end_auth_session(). Fix this by replacing the early return with a goto to the existing 'out' label, which already handles both cleanup operations. The redundant tpm_buf_destroy() call is removed since 'out' takes care of it.

2026-04-21tpm_crb: Convert ACPI driver to a platform oneRafael J. Wysocki
In all cases in which a struct acpi_driver is used for binding a driver to an ACPI device object, a corresponding platform device is created by the ACPI core and that device is regarded as a proper representation of underlying hardware. Accordingly, a struct platform_driver should be used by driver code to bind to that device. There are multiple reasons why drivers should not bind directly to ACPI device objects [1]. Overall, it is better to bind drivers to platform devices than to their ACPI companions, so convert the tpm_crb ACPI driver to a platform one. While this is not expected to alter functionality, it changes sysfs layout and so it will be visible to user space.

The function kgdb_wait() was folded into the static function kgdb_cpu_enter() by commit 62fae312197a ("kgdb: eliminate kgdb_wait(), all cpus enter the same way"). Update the four stale references accordingly: - include/linux/kgdb.h and arch/x86/kernel/kgdb.c: the kgdb_roundup_cpus() kdoc describes what other CPUs are rounded up to call. Because kgdb_cpu_enter() is static, the correct public entry point is kgdb_handle_exception(); also fix a pre-existing grammar error ("get them be" -> "get them into") and reflow the text. - kernel/debug/debug_core.c: replace with the generic description "the debug trap handler", since the actual entry path is architecture-specific. - kernel/debug/gdbstub.c: kgdb_cpu_enter() is correct here (it describes internal state, not a call target); add the missing parentheses.

2026-04-22tracing/fprobe: Check the same type fprobe on table as the unregistered oneMasami Hiramatsu (Google)
Commit 2c67dc457bc6 ("tracing: fprobe: optimization for entry only case") introduced a different ftrace_ops for entry-only fprobes. However, when unregistering an fprobe, the kernel only checks if another fprobe exists at the same address, without checking which type of fprobe it is. If different fprobes are registered at the same address, the same address will be registered in both fgraph_ops and ftrace_ops, but only one of them will be deleted when unregistering. (the one removed first will not be deleted from the ops). This results in junk entries remaining in either fgraph_ops or ftrace_ops. For example: ======= cd /sys/kernel/tracing # 'Add entry and exit events on the same place' echo 'f:event1 vfs_read' >> dynamic_events echo 'f:event2 vfs_read%return' >> dynamic_events # 'Enable both of them' echo 1 > events/fprobes/enable cat enabled_functions vfs_read (2) ->arch_ftrace_ops_list_func+0x0/0x210 # 'Disable and remove exit event' echo 0 > events/fprobes/event2/enable echo -:event2 >> dynamic_events # 'Disable and remove all events' echo 0 > events/fprobes/enable echo > dynamic_events # 'Add another event' echo 'f:event3 vfs_open%return' > dynamic_events cat dynamic_events f:fprobes/event3 vfs_open%return echo 1 > events/fprobes/enable cat enabled_functions vfs_open (1) tramp: 0xffffffffa0001000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 subops: {ent:fprobe_fgraph_entry+0x0/0x620 ret:fprobe_return+0x0/0x150} vfs_read (1) tramp: 0xffffffffa0001000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 subops: {ent:fprobe_fgraph_entry+0x0/0x620 ret:fprobe_return+0x0/0x150} ======= As you can see, an entry for the vfs_read remains. To fix this issue, when unregistering, the kernel should also check if there is the same type of fprobes still exist at the same address, and if not, delete its entry from either fgraph_ops or ftrace_ops.

2026-04-21arm64: dts: amlogic: t7: khadas-vim4: fix memory layout for 8GB RAMNick Xie
The Khadas VIM4 features 8GB of LPDDR4X RAM. The previous memory node mapped a single incorrect region. This caused the kernel to map MMIO and secure firmware (ATF/TrustZone) memory holes as standard RAM, leading to an Asynchronous SError Interrupt during early boot (paging_init) when the kernel attempted to clear those pages. Fix this by splitting the 8GB memory layout into three separate regions to properly avoid the memory holes (e.g., 0xe0000000 - 0xffffffff): - 3.5GB @ 0x000000000 - 3.5GB @ 0x100000000 - 1.0GB @ 0x200000000 Signed-off-by: Nick Xie <nick@khadas.com> Suggested-by: Ronald Claveau <linux-kernel-dev@aliel.fr> Link: https://patch.msgid.link/20260319023446.3422695-1-nick@khadas.com Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org>

2026-04-21wifi: ath12k: Fix invalid IRQ requests during AHB probeAaradhana Sahu
ath12k_ahb_config_ext_irq() iterates over ATH12K_EXT_IRQ_NUM_MAX (16) entries while checking TX ring masks, but the tcl_to_wbm_rbm_map array contains only DP_TCL_NUM_RING_MAX (4) valid elements. When the iterator (j) is greater than or equal to DP_TCL_NUM_RING_MAX, it accesses tcl_to_wbm_rbm_map[j] out of bounds. This results in reading uninitialized memory for wbm_ring_num, causing the driver to evaluate incorrect BIT() conditions and request IRQs for rings that do not have an assigned interrupt line or device tree entry. This leads to request_irq() failures with -ENXIO or -EINVAL during ath12k AHB probe. Fix this by splitting the loop into two separate loops: one iterating over DP_TCL_NUM_RING_MAX for TX ring, and another iterating over ATH12K_EXT_IRQ_NUM_MAX for remaining IRQ entries. Also add a bounds check for num_irq.

2026-04-21net/sched: sch_dualpi2: drain both C-queue and L-queue in dualpi2_change()Chia-Yu Chang
Fix dualpi2_change() to correctly enforce updated limit and memlimit values after a configuration change of the dualpi2 qdisc. Before this patch, dualpi2_change() always attempted to dequeue packets via the root qdisc (C-queue) when reducing backlog or memory usage, and unconditionally assumed that a valid skb will be returned. When traffic classification results in packets being queued in the L-queue while the C-queue is empty, this leads to a NULL skb dereference during limit or memlimit enforcement. This is fixed by first dequeuing from the C-queue path if it is non-empty. Once the C-queue is empty, packets are dequeued directly from the L-queue. Return values from qdisc_dequeue_internal() are checked for both queues. When dequeuing from the L-queue, the parent qdisc qlen and backlog counters are updated explicitly to keep overall qdisc statistics consistent.

2026-04-21Merge branch 'net-sleepable-ndo_set_rx_mode'Paolo Abeni
Stanislav Fomichev says: ==================== net: sleepable ndo_set_rx_mode This series adds a new ndo_set_rx_mode_async callback that enables drivers to handle address list updates in a sleepable context. The current ndo_set_rx_mode is called under the netif_addr_lock spinlock with BHs disabled, which prevents drivers from sleeping. This is problematic for ops-locked drivers that need to sleep. The approach: 1. Add snapshot/reconcile infrastructure for address lists 2. Introduce dev_rx_mode_work that takes snapshots under the lock, drops the lock, calls the driver, then reconciles changes back 3. Move promiscuity handling into the scheduled work as well 4. Convert existing ops-locked drivers to ndo_set_rx_mode_async 5. Add a warning for ops-locked drivers still using ndo_set_rx_mode 6. Add a selftest exercising the team+bridge+macvlan topology that triggers the addr_lock -> ops_lock ordering issue ==================== Link: https://patch.msgid.link/20260416185712.2155425-1-sdf@fomichev.me Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2026-04-21selftests: net: use ip commands instead of teamd in team rx_mode testStanislav Fomichev
Replace teamd daemon usage with ip link commands for team device setup. teamd -d daemonizes and returns to the shell before port addition completes, creating a race: the test may create the macvlan (and check for its address on a slave) before teamd has finished adding ports. This makes the test inherently dependent on scheduling timing. Using ip commands makes port addition synchronous, removing the race and making the test deterministic.
