2025-03-21selftests/timers: Improve skew_consistency by testing with other clockidsJohn Stultz
Lei Chen reported a bug with CLOCK_MONOTONIC_COARSE having inconsistencies when NTP is adjusting the clock frequency. This has gone seemingly undetected for ~15 years, illustrating a clear gap in our testing. The skew_consistency test is intended to catch this sort of problem, but was focused on only evaluating CLOCK_MONOTONIC, and thus missed the problem on CLOCK_MONOTONIC_COARSE. So adjust the test to run with all clockids for 60 seconds each instead of 10 minutes with just CLOCK_MONOTONIC.

2025-03-21timekeeping: Fix possible inconsistencies in _COARSE clockidsJohn Stultz
Lei Chen raised an issue with CLOCK_MONOTONIC_COARSE seeing time inconsistencies. Lei tracked down that this was being caused by the adjustment tk->tkr_mono.xtime_nsec -= offset; which is made to compensate for the unaccumulated cycles in offset when the multiplicator is adjusted forward, so that the non-_COARSE clockids don't see inconsistencies. However, the _COARSE clockid getter functions use the adjusted xtime_nsec value directly and do not compensate the negative offset via the clocksource delta multiplied with the new multiplicator. In that case the caller can observe time going backwards in consecutive calls. By design, this negative adjustment should be fine, because the logic run from timekeeping_adjust() is done after it accumulated approximately multiplicator * interval_cycles into xtime_nsec. The accumulated value is always larger then the mult_adj * offset value, which is subtracted from xtime_nsec. Both operations are done together under the tk_core.lock, so the net change to xtime_nsec is always always be positive. However, do_adjtimex() calls into timekeeping_advance() as well, to to apply the NTP frequency adjustment immediately. In this case, timekeeping_advance() does not return early when the offset is smaller then interval_cycles. In that case there is no time accumulated into xtime_nsec. But the subsequent call into timekeeping_adjust(), which modifies the multiplicator, subtracts from xtime_nsec to correct for the new multiplicator. Here because there was no accumulation, xtime_nsec becomes smaller than before, which opens a window up to the next accumulation, where the _COARSE clockid getters, which don't compensate for the offset, can observe the inconsistency. To fix this, rework the timekeeping_advance() logic so that when invoked from do_adjtimex(), the time is immediately forwarded to accumulate also the sub-interval portion into xtime. That means the remaining offset becomes zero and the subsequent multiplier adjustment therefore does not modify xtime_nsec. There is another related inconsistency. If xtime is forwarded due to the instantaneous multiplier adjustment, the NTP error, which was accumulated with the previous setting, becomes meaningless. Therefore clear the NTP error as well, after forwarding the clock for the instantaneous multiplier update.

2025-03-21mptcp: sockopt: fix getting freebind & transparentMatthieu Baerts (NGI0)
When adding a socket option support in MPTCP, both the get and set parts are supposed to be implemented. IP(V6)_FREEBIND and IP(V6)_TRANSPARENT support for the setsockopt part has been added a while ago, but it looks like the get part got forgotten. It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types. Everything was in place to expose it, just the last step was missing. Only new code is added to cover these specific getsockopt(), that seems safe.

It should have been present as a way to verify a setting has been set as expected, and not to act differently from TCP or any other socket types. Not supporting this getsockopt(IPV6_V6ONLY) blocks some apps which want to check the default value, before doing extra actions. On Linux, the default value is 0, but this can be changed with the net.ipv6.bindv6only sysctl knob. On Windows, it is set to 1 by default.

2025-03-21Merge branch 'netconsole-add-support-for-userdata-release'Paolo Abeni
Breno Leitao says: ==================== netconsole: Add support for userdata release I am submitting a series of patches that introduce a new feature for the netconsole subsystem, specifically the addition of the 'release' field to the sysdata structure. This feature allows the kernel release/version to be appended to the userdata dictionary in every message sent, enhancing the information available for debugging and monitoring purposes. This complements the already supported release prepend feature, which was added some time ago. The release prepend appends the release information at the message header, which is not ideal for two reasons: 1) It is difficult to determine if a message includes this information, making it hard and resource-intensive to parse. 2) When a message is fragmented, the release information is appended to every message fragment, consuming valuable space in the packet. The "release prepend" feature was created before the concept of userdata and sysdata. Now that this format has proven successful, we are implementing the release feature as part of this enhanced structure. This patch series aims to improve the netconsole subsystem by providing a more efficient and user-friendly way to include kernel release information in messages. I believe these changes will significantly aid in system analysis and troubleshooting.

2025-03-21ALSA: timer: Don't take register_mutex with copy_from/to_user()Takashi Iwai
The infamous mmap_lock taken in copy_from/to_user() can be often problematic when it's called inside another mutex, as they might lead to deadlocks. In the case of ALSA timer code, the bad pattern is with guard(mutex)(&register_mutex) that covers copy_from/to_user() -- which was mistakenly introduced at converting to guard(), and it had been carefully worked around in the past. This patch fixes those pieces simply by moving copy_from/to_user() out of the register mutex lock again.

pcie_bwctrl_select_speed() should take __fls() of the speed bit, not return it as a raw value. Instead of directly returning 2.5GT/s speed bit, simply assign the fallback speed (2.5GT/s) into supported_speeds variable to share the normal return path that calls pcie_supported_speeds2target_speed() to calculate __fls(). This code path is not very likely to execute because pcie_get_supported_speeds() should provide valid ->supported_speeds but a spec violating device could fail to synthesize any speed in pcie_get_supported_speeds(). It could also happen in case the supported_speeds intersection is empty (also a violation of the current PCIe specs).

2025-03-21docs: dt-bindings: Specify ordering for properties within groupsDragan Simic
Ordering of the individual properties inside each property group benefits from applying natural sort order [1] by the property names, because it results in more logical and more usable property lists, similarly to what's already the case with the alpha-numerical ordering of the nodes without unit addresses. Let's have this clearly specified in the DTS coding style, and let's expand the provided node example a bit, to actually show the results of applying natural sort order. Applying strict alpha-numerical ordering can result in property lists that are suboptimal from the usability standpoint. For the provided example, which stems from a real-world DT, [2][3][4] applying strict alpha-numerical ordering produces the following undesirable result: vdd-0v9-supply = <&board_vreg1>; vdd-12v-supply = <&board_vreg3>; vdd-1v8-supply = <&board_vreg4>; vdd-3v3-supply = <&board_vreg2>; Having the properties sorted in natural order by their associated voltages is more logical, more usable, and a bit more consistent.

2025-03-21drm/amdgpu/sdma_v4_4_2: update VM flush implementation for SDMAJesse.zhang@amd.com
This commit updates the VM flush implementation for the SDMA engine. - Added a new function `sdma_v4_4_2_get_invalidate_req` to construct the VM_INVALIDATE_ENG0_REQ register value for the specified VMID and flush type. This function ensures that all relevant page table cache levels (L1 PTEs, L2 PTEs, and L2 PDEs) are invalidated. - Modified the `sdma_v4_4_2_ring_emit_vm_flush` function to use the new `sdma_v4_4_2_get_invalidate_req` function. The updated function emits the necessary register writes and waits to perform a VM flush for the specified VMID. It updates the PTB address registers and issues a VM invalidation request using the specified VM invalidation engine. - Included the necessary header file `gc/gc_9_0_sh_mask.h` to provide access to the required register definitions. v2: vm flush by the vm inalidation packet (Lijo) v3: code stle and define thh macro for the vm invalidation packet (Christian) v4: Format definition sdma vm invalidate packet (Lijo) Suggested-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Jesse Zhang <jesse.zhang@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2025-03-21drm/amdgpu: Optimize VM invalidation engine allocation and synchronize GPU ↵Jesse.zhang@amd.com
TLB flush - Modify the VM invalidation engine allocation logic to handle SDMA page rings. SDMA page rings now share the VM invalidation engine with SDMA gfx rings instead of allocating a separate engine. This change ensures efficient resource management and avoids the issue of insufficient VM invalidation engines. - Add synchronization for GPU TLB flush operations in gmc_v9_0.c. Use spin_lock and spin_unlock to ensure thread safety and prevent race conditions during TLB flush operations. This improves the stability and reliability of the driver, especially in multi-threaded environments. v2: replace the sdma ring check with a function `amdgpu_sdma_is_page_queue` to check if a ring is an SDMA page queue.(Lijo) v3: Add GC version check, only enabled on GC9.4.3/9.4.4/9.5.0 v4: Fix code style and add more detailed description (Christian) v5: Remove dependency on vm_inv_eng loop order, explicitly lookup shared inv_eng(Christian/Lijo) v6: Added search shared ring function amdgpu_sdma_get_shared_ring (Lijo) Suggested-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Jesse Zhang <jesse.zhang@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-03-21drm/amdgpu/gfx11: Add Cleaner Shader Support for GFX11.5 GPUsSrinivasan Shanmugam
Enable the cleaner shader for GFX11.5.0/11.5.1 GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX11.5.0/11.5.1 GPUs, previously available for GFX11.0.3. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.
