2025-11-18net: stmmac: Disable EEE RX clock stop when VLAN is enabledOvidiu Panait
On the Renesas RZ/V2H EVK platform, where the stmmac MAC is connected to a Microchip KSZ9131RNXI PHY, creating or deleting VLAN interfaces may fail with timeouts: # ip link add link end1 name end1.5 type vlan id 5 15c40000.ethernet end1: Timeout accessing MAC_VLAN_Tag_Filter RTNETLINK answers: Device or resource busy Disabling EEE at runtime avoids the problem: # ethtool --set-eee end1 eee off # ip link add link end1 name end1.5 type vlan id 5 # ip link del end1.5 The stmmac hardware requires the receive clock to be running when writing certain registers, such as those used for MAC address configuration or VLAN filtering. However, by default the driver enables Energy Efficient Ethernet (EEE) and allows the PHY to stop the receive clock when the link is idle. As a result, the RX clock might be stopped when attempting to access these registers, leading to timeouts and other issues. Commit dd557266cf5fb ("net: stmmac: block PHY RXC clock-stop") addressed this issue for most register accesses by wrapping them in phylink_rx_clk_stop_block()/phylink_rx_clk_stop_unblock() calls. However, VLAN add/delete operations may be invoked with bottom halves disabled, where sleeping is not allowed, so using these helpers is not possible. Therefore, to fix this, disable the RX clock stop feature in the phylink configuration if VLAN features are set. This ensures the RX clock remains active and register accesses succeed during VLAN operations.

2025-11-18net: stmmac: Fix VLAN 0 deletion in vlan_del_hw_rx_fltr()Ovidiu Panait
When the "rx-vlan-filter" feature is enabled on a network device, the 8021q module automatically adds a VLAN 0 hardware filter when the device is brought administratively up. For stmmac, this causes vlan_add_hw_rx_fltr() to create a new entry for VID 0 in the mac_device_info->vlan_filter array, in the following format: VLAN_TAG_DATA_ETV | VLAN_TAG_DATA_VEN | vid Here, VLAN_TAG_DATA_VEN indicates that the hardware filter is enabled for that VID. However, on the delete path, vlan_del_hw_rx_fltr() searches the vlan_filter array by VID only, without verifying whether a VLAN entry is enabled. As a result, when the 8021q module attempts to remove VLAN 0, the function may mistakenly match a zero-initialized slot rather than the actual VLAN 0 entry, causing incorrect deletions and leaving stale entries in the hardware table. Fix this by verifying that the VLAN entry's enable bit (VLAN_TAG_DATA_VEN) is set before matching and deleting by VID. This ensures only active VLAN entries are removed and avoids leaving stale entries in the VLAN filter table, particularly for VLAN ID 0.

2025-11-18platform/x86: asus-armoury: add ppt_* and nv_* tuning knobsLuke D. Jones
Adds the ppt_* and nv_* tuning knobs that are available via WMI methods and adds proper min/max levels plus defaults. The min/max are defined by ASUS and typically gained by looking at what they allow in the ASUS Armoury Crate application - ASUS does not share the values outside of this. It could also be possible to gain the AMD values by use of ryzenadj and testing for the minimum stable value. The general rule of thumb for adding to the match table is that if the model range has a single CPU used throughout, then the DMI match can omit the last letter of the model number as this is the GPU model. If a min or max value is not provided it is assumed that the particular setting is not supported. for example ppt_pl2_sppt_min/max is not set. If a <ppt_setting>_def is not set then the default is assumed to be <ppt_setting>_max It is assumed that at least AC settings are available so that the firmware attributes will be created - if no DC table is available and power is on DC, then reading the attributes is -ENODEV.

2025-11-17Input: rename INPUT_PROP_HAPTIC_TOUCHPAD to INPUT_PROP_PRESSUREPADPeter Hutterer
And expand it to encompass all pressure pads. Definition: "pressure pad" as used here as includes all touchpads that use physical pressure to convert to click, without physical hinges. Also called haptic touchpads in general parlance, Synaptics calls them ForcePads. Most (all?) pressure pads are currently advertised as INPUT_PROP_BUTTONPAD. The suggestion to identify them as pressure pads by defining the resolution on ABS_MT_PRESSURE has been in the docs since commit 20ccc8dd38a3 ("Documentation: input: define ABS_PRESSURE/ABS_MT_PRESSURE resolution as grams") but few devices provide this information. In userspace it's thus impossible to determine whether a device is a true pressure pad (pressure equals pressure) or a normal clickpad with (pressure equals finger size). Commit 7075ae4ac9db ("Input: add INPUT_PROP_HAPTIC_TOUCHPAD") introduces INPUT_PROP_HAPTIC_TOUCHPAD but restricted it to those touchpads that have support for userspace-controlled effects. Let's expand and rename that definition to include all pressure pad touchpads since those that do support FF effects can be identified by the presence of the FF_HAPTIC bit. This means: - clickpad: INPUT_PROP_BUTTONPAD - pressurepad: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD - pressurepad with configurable haptics: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD + FF_HAPTIC Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Acked-by: Benjamin Tissoires <bentiss@kernel.org> Link: https://patch.msgid.link/20251106114534.GA405512@tassie Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2025-11-17functionfs: fix the open/removal racesAl Viro
ffs_epfile_open() can race with removal, ending up with file->private_data pointing to freed object. There is a total count of opened files on functionfs (both ep0 and dynamic ones) and when it hits zero, dynamic files get removed. Unfortunately, that removal can happen while another thread is in ffs_epfile_open(), but has not incremented the count yet. In that case open will succeed, leaving us with UAF on any subsequent read() or write(). The root cause is that ffs->opened is misused; atomic_dec_and_test() vs. atomic_add_return() is not a good idea, when object remains visible all along. To untangle that * serialize openers on ffs->mutex (both for ep0 and for dynamic files) * have dynamic ones use atomic_inc_not_zero() and fail if we had zero ->opened; in that case the file we are opening is doomed. * have the inodes of dynamic files marked on removal (from the callback of simple_recursive_removal()) - clear ->i_private there. * have open of dynamic ones verify they hadn't been already removed, along with checking that state is FFS_ACTIVE.

ffs_data_closed() has a seriously confusing logics in it: in addition to the normal "decrement a counter and do some work if it hits zero" there's "... and if it has somehow become negative, do that" bit. It's not a race, despite smelling rather fishy. What really happens is that in addition to "call that on close of files there, to match the increments of counter on opens" there's one call in ->kill_sb(). Counter starts at 0 and never goes negative over the lifetime of filesystem (or we have much worse problems everywhere - ->release() call of some file somehow unpaired with successful ->open() of the same). At the filesystem shutdown it will be 0 or, again, we have much worse problems - filesystem instance destroyed with files on it still open. In other words, at that call and at that call alone the decrement would go from 0 to -1, hitting that chunk (and not hitting the "if it hits 0" part). So that check is a weirdly spelled "called from ffs_kill_sb()". Just expand the call in the latter and kill the misplaced chunk in ffs_data_closed().

Move the original inline helpers (e.g., zl3073x_ref_is_enabled) to the new headers (ref.h, etc.) and make them operate on a const struct ... * pointer. 2. Create new zl3073x_dev_... prefixed functions in core.h (e.g., zl3073x_dev_ref_is_enabled) and Implement these _dev_ functions to fetch state using a new ..._state_get() helper and then call the non-prefixed helper. 3. Update all driver-internal callers (in dpll.c, prop.c, etc.) to use the new zl3073x_dev_... functions.

2025-11-17dpll: zl3073x: Store raw register values instead of parsed stateIvan Vecera
The zl3073x_ref, zl3073x_out and zl3073x_synth structures previously stored state that was parsed from register reads. This included values like boolean 'enabled' flags, synthesizer selections, and pre-calculated frequencies. This commit refactors the state management to store the raw register values directly in these structures. The various inline helper functions are updated to parse these raw values on-demand using FIELD_GET.

2025-11-17s390/qeth: Handle ambiguous OSA RCs in s390dbfAswin Karuvally
OSA Express defines a number of return codes whose meaning is determined by the issuing command, making them ambiguous. The important ones are reported as debug messages through the s390 debug feature. The qeth driver currently does not take the issuing command into account when interpreting the return code which sometimes leads to incorrect debug messages. Implement a mechanism to interpret and report these return codes properly. While at it, remove extern keyword and fix indentation for function declarations to be in line with Linux kernel coding style.

Airoha_eth driver forwards offloaded uplink traffic (packets received on GDM1 and forwarded to GDM{3,4}) to GDM2 in order to apply hw QoS. This is correct if the device does not support a dedicated GDM2 port. In this case, in order to enable hw offloading for uplink traffic, the packets should be sent to GDM{3,4} directly.

2025-11-17r8169: bail out from probe if fiber mode is detected on RTL8127AFHeiner Kallweit
It was reported that on a card with RTL8127AF (SFP + DAC) link-up isn't detected. Realtek hides the SFP behind the internal PHY, which isn't behaving fully compliance with clause 22 any longer in fiber mode. Due to not having access to chip documentation there isn't much I can do for now. Instead of silently failing to detect link-up in fiber mode, inform the user that fiber mode isn't support and bail out. The logic to detect fiber mode is borrowed from Realtek's r8127 driver.

The "phy-mode" property of devicetree indicates whether the PCB has delay now, which means the mac needs to modify the PHY mode based on whether there is an internal delay in the mac. This modification is similar for many ethernet drivers. To simplify code, define the helper phy_fix_phy_mode_for_mac_delays(speed, mac_txid, mac_rxid) to fix PHY mode based on whether mac adds internal delay.

Add a global workqueue to periodically run mana_query_gf_stats every 2 seconds to get the latest info in eth_stats and define a driver capability flag to notify hardware of the periodic queries. To avoid repeated failures and log flooding, the workqueue is not rescheduled if mana_query_gf_stats fails on HWC timeout error and the stats are reset to 0.

Move hardware counter (HC) statistics from mana_port_context to mana_context to enable sharing stats across multiple network ports on the same MANA VF. Previously, each network port queried hardware counters independently using MANA_QUERY_GF_STAT command (GF = Generic Function stats from GDMA hardware), resulting in redundant queries when multiple ports existed on the same device.
