2025-04-01platform/x86: ISST: Correct command storage data lengthSrinivas Pandruvada
After resume/online turbo limit ratio (TRL) is restored partially if the admin explicitly changed TRL from user space. A hash table is used to store SST mail box and MSR settings when modified to restore those settings after resume or online. This uses a struct isst_cmd field "data" to store these settings. This is a 64 bit field. But isst_store_new_cmd() is only assigning as u32. This results in truncation of 32 bits. Change the argument to u64 from u32.

2025-04-01platform/x86: thinkpad_acpi: disable ACPI fan access for T495* and E560Eduard Christian Dumitrescu
T495, T495s, and E560 laptops have the FANG+FANW ACPI methods (therefore fang_handle and fanw_handle are not NULL) but they do not actually work, which results in a "No such device or address" error. The DSDT table code for the FANG+FANW methods doesn't seem to do anything special regarding the fan being secondary. The bug was introduced in commit 57d0557dfa49 ("platform/x86: thinkpad_acpi: Add Thinkpad Edge E531 fan support"), which added a new fan control method via the FANG+FANW ACPI methods. Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods. Fan access and control is restored after forcing the legacy non-ACPI fan control method by setting both fang_handle and fanw_handle to NULL.

2025-04-01platform/x86: thinkpad_acpi: Fix NULL pointer dereferences while probingKurt Borja
Some subdrivers make use of the global reference tpacpi_pdev during initialization, which is called from the platform driver's probe. However, after the commit 38b9ab80db31 ("platform/x86: thinkpad_acpi: Move subdriver initialization to tpacpi_pdriver's probe.") this variable is only properly initialized *after* probing and this can result in a NULL pointer dereference. In order to fix this without reverting the commit, register the platform bundle in two steps, first create and initialize tpacpi_pdev, then register the driver synchronously with platform_driver_probe(). This way the benefits of commit 38b9ab80db31 are preserved. Additionally, the commit 43fc63a1e8f6 ("platform/x86: thinkpad_acpi: Move HWMON initialization to tpacpi_hwmon_pdriver's probe") introduced a similar problem, however tpacpi_sensors_pdev is only used once inside the probe, so replace the global reference with the one given by the probe.

2025-03-20platform: cznic: turris-omnia-mcu: Add support for digital message signing ↵Marek Behún
with HW private key Add support for digital message signing with the private key stored in the MCU. Turris Omnia boards with MKL MCUs have a NIST256p ECDSA private key generated and burned into MCU's flash when manufactured. The private key is not readable from the MCU, but MCU allows for signing messages with it and retrieving the public key. This is exposed to userspace via the keyctl API. In userspace, the user can look at /proc/keys or list the keyring: $ cat /proc/keys 0a3b7cd3 ... keyring .turris-signing-keys: 1 3caf0b1a ... turris-om Turris Omnia SN 0000000A1000023 MCU ECDSA k... $ keyctl rlist %:.turris-signing-keys 1018104602 To get the public key: $ keyctl read 1018104602 33 bytes of data in key: 025d9108 1fb538ae 8435c88b b4379171 d6b158a9 55751b91 1d23e6a9 d017f4b2 1c To sign a message: $ dd if=/dev/urandom of=msg_to_sign bs=32 count=1 $ keyctl pkey_sign 1018104602 0 msg_to_sign >signature Signed-off-by: Marek Behún <kabel@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2025-03-20platform: cznic: Add keyctl helpers for Turris platformMarek Behún
Some Turris devices support signing messages with a per-device unique asymmetric key that was created on the device at manufacture time. Add helper module that helps to expose this ability via the keyctl() syscall. A device-specific driver can register a signing key by calling devm_turris_signing_key_create(). Both the `.turris-signing-keys` keyring and the signing key are created with only the VIEW, READ and SEARCH permissions for userspace - it is impossible to link / unlink / move them, set their attributes, or unlink the keyring from userspace.

2025-03-20drm/bridge: Add encoder parameter to drm_bridge_funcs.attachMaxime Ripard
The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

2025-03-16platform/chrome: cros_ec_lpc: prepare for hw_protection_shutdown removalAhmad Fatoum
In the general case, a driver doesn't know which of system shutdown or reboot is the better action to take to protect hardware in an emergency situation. For this reason, hw_protection_shutdown is going to be removed in favor of hw_protection_trigger, which defaults to shutdown, but may be configured at kernel runtime to be a reboot instead. The ChromeOS EC situation is different as we do know that shutdown is the correct action as the EC is programmed to force reset after the short period, thus replace hw_protection_shutdown with __hw_protection_trigger with HWPROT_ACT_SHUTDOWN as argument to maintain the same behavior. No functional change.

2025-03-11platform/x86/amd/pmf: fix cleanup in amd_pmf_init_smart_pc()Dan Carpenter
There are a few problems in this code: First, if amd_pmf_tee_init() fails then the function returns directly instead of cleaning up. We cannot simply do a "goto error;" because the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool); and amd_pmf_tee_deinit() calls it as well leading to a double free. I have re-written this code to use an unwind ladder to free the allocations. Second, if amd_pmf_start_policy_engine() fails on every iteration though the loop then the code calls amd_pmf_tee_deinit() twice which is also a double free. Call amd_pmf_tee_deinit() inside the loop for each failed iteration. Also on that path the error codes are not necessarily negative kernel error codes. Set the error code to -EINVAL. There is a very subtle third bug which is that if the call to input_register_device() in amd_pmf_register_input_device() fails then we call input_unregister_device() on an input device that wasn't registered. This will lead to a reference counting underflow because of the device_del(&dev->dev) in __input_unregister_device(). It's unlikely that anyone would ever hit this bug in real life.
