2025-07-23tpm: Replace scnprintf() with sysfs_emit() and sysfs_emit_at() in sysfs show ↵Chelsy Ratnawat
functions Documentation/filesystems/sysfs.rst mentions that show() should only use sysfs_emit() or sysfs_emit_at() when formating the value to be returned to user space. So replace scnprintf() with sysfs_emit().

2025-07-23tpm: tpm_crb_ffa: try to probe tpm_crb_ffa when it's built-inYeoreum Yun
To generate the boot_aggregate log in the IMA subsystem using TPM PCR values, the TPM driver must be built as built-in and must be probed before the IMA subsystem is initialized. However, when the TPM device operates over the FF-A protocol using the CRB interface, probing fails and returns -EPROBE_DEFER if the tpm_crb_ffa device — an FF-A device that provides the communication interface to the tpm_crb driver — has not yet been probed. This issue occurs because both crb_acpi_driver_init() and tpm_crb_ffa_driver_init() are registered with device_initcall. As a result, crb_acpi_driver_init() may be invoked before tpm_crb_ffa_driver_init(), which is responsible for probing the tpm_crb_ffa device. When this happens, IMA fails to detect the TPM device and logs the following message: | ima: No TPM chip found, activating TPM-bypass! Consequently, it cannot generate the boot_aggregate log with the PCR values provided by the TPM. To resolve this issue, the tpm_crb_ffa_init() function explicitly attempts to probe the tpm_crb_ffa by register tpm_crb_ffa driver so that when tpm_crb_ffa device is created before tpm_crb_ffa_init(), probe the tpm_crb_ffa device in tpm_crb_ffa_init() to finish probe the TPM device completely. This ensures that the TPM device using CRB over FF-A can be successfully probed, even if crb_acpi_driver_init() is called first.

2025-07-23firmware: arm_ffa: Change initcall level of ffa_init() to rootfs_initcallYeoreum Yun
The Linux IMA (Integrity Measurement Architecture) subsystem used for secure boot, file integrity, or remote attestation cannot be a loadable module for few reasons listed below: o Boot-Time Integrity: IMA’s main role is to measure and appraise files before they are used. This includes measuring critical system files during early boot (e.g., init, init scripts, login binaries). If IMA were a module, it would be loaded too late to cover those. o TPM Dependency: IMA integrates tightly with the TPM to record measurements into PCRs. The TPM must be initialized early (ideally before init_ima()), which aligns with IMA being built-in. o Security Model: IMA is part of a Trusted Computing Base (TCB). Making it a module would weaken the security model, as a potentially compromised system could delay or tamper with its initialization. IMA must be built-in to ensure it starts measuring from the earliest possible point in boot which inturn implies TPM must be initialised and ready to use before IMA. To enable integration of tpm_event_log with the IMA subsystem, the TPM drivers (tpm_crb and tpm_crb_ffa) also needs to be built-in. However with FF-A driver also being initialised at device initcall level, it can lead to an initialization order issue where: - crb_acpi_driver_init() may run before tpm_crb_ffa_driver()_init and ffa_init() - As a result, probing the TPM device via CRB over FFA is deferred - ima_init() (called as a late initcall) runs before deferred probe completes, IMA fails to find the TPM and logs the below error: | ima: No TPM chip found, activating TPM-bypass! Eventually it fails to generate boot_aggregate with PCR values. Because of the above stated dependency, the ffa driver needs to initialised before tpm_crb_ffa module to ensure IMA finds the TPM successfully when present.

2025-07-23tpm/tpm_svsm: support TPM_CHIP_FLAG_SYNCStefano Garzarella
This driver does not support interrupts, and receiving the response is synchronous with sending the command. Enable synchronous send() with TPM_CHIP_FLAG_SYNC, which implies that ->send() already fills the provided buffer with a response, and ->recv() is not implemented. Keep using the same pre-allocated buffer to avoid having to allocate it for each command. We need the buffer to have the header required by the SVSM protocol and the command contiguous in memory.

2025-07-23tpm: support devices with synchronous send()Stefano Garzarella
Some devices do not support interrupts and provide a single synchronous operation to send the command and receive the response on the same buffer. Currently, these types of drivers must use an internal buffer where they temporarily store the response between .send() and .recv() calls. Introduce a new flag (TPM_CHIP_FLAG_SYNC) to support synchronous send(). If that flag is set by the driver, tpm_try_transmit() will use the send() callback to send the command and receive the response on the same buffer synchronously. In that case send() return the number of bytes of the response on success, or -errno on failure.

2025-07-23tpm: add bufsiz parameter in the .send callbackStefano Garzarella
Add a new `bufsiz` parameter to the `.send` callback in `tpm_class_ops`. This parameter will allow drivers to differentiate between the actual command length to send and the total buffer size. Currently `bufsiz` is not used, but it will be used to implement devices with synchronous send() to send the command and receive the response on the same buffer. Also rename the previous parameter `len` to `cmd_len` in the declaration to make it clear that it contains the length in bytes of the command stored in the buffer. The semantics don't change and it can be used as before by drivers. This is an optimization since the drivers could get it from the header, but let's avoid duplicating code. While we are here, resolve a checkpatch warning: WARNING: Unnecessary space before function pointer arguments #66: FILE: include/linux/tpm.h:90: + int (*send) (struct tpm_chip *chip, u8 *buf, size_t bufsiz, Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Suggested-by: Jarkko Sakkinen <jarkko@kernel.org> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

2025-07-22PCI/pwrctrl: Create pwrctrl devices only when CONFIG_PCI_PWRCTRL is enabledManivannan Sadhasivam
If devicetree describes power supplies related to a PCI device, we unnecessarily created a pwrctrl device even if CONFIG_PCI_PWRCTL was not enabled. We only need pci_pwrctrl_create_device() when CONFIG_PCI_PWRCTRL is enabled. Compile it out when CONFIG_PCI_PWRCTRL is not enabled. When pci_pwrctrl_create_device() creates and returns a pwrctrl device, pci_scan_device() doesn't enumerate the PCI device. It assumes the pwrctrl core will rescan the bus after turning on the power. However, if CONFIG_PCI_PWRCTRL is not enabled, the rescan never happens, which breaks PCI enumeration on any system that describes power supplies in devicetree but does not use pwrctrl. Jim reported that some brcmstb platforms break this way. The brcmstb driver is still broken if CONFIG_PCI_PWRCTRL is enabled, but this commit at least allows brcmstb to work when it's NOT enabled.

2025-07-22vt: defkeymap: Map keycodes above 127 to K_HOLEMyrrh Periwinkle
The maximum number of keycodes got bumped to 256 a very long time ago, but the default keymaps were never adjusted to match. This is causing the kernel to interpret keycodes above 127 as U+0000 if the shipped generated keymap is used. Fix this by mapping all keycodes above 127 to K_HOLE so the kernel ignores them. The contents of this patche were generated by rerunning `loadkeys --mktable --unicode` and only including the changes to map keycodes above 127 to K_HOLE.

2025-07-22serial: qcom-geni: Enable Serial on SA8255p Qualcomm platformsPraveen Talari
The Qualcomm automotive SA8255p SoC relies on firmware to configure platform resources, including clocks, interconnects and TLMM. The driver requests resources operations over SCMI using power and performance protocols. The SCMI power protocol enables or disables resources like clocks, interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs, such as resume/suspend, to control power states(on/off). The SCMI performance protocol manages UART baud rates, with each baud rate represented by a performance level. The driver uses the dev_pm_opp_set_level() API to request the desired baud rate by specifying the performance level.

2025-07-22serial: qcom-geni: Enable PM runtime for serial driverPraveen Talari
The GENI serial driver currently handles power resource management through calls to the statically defined geni_serial_resources_on() and geni_serial_resources_off() functions. This approach reduces modularity and limits support for platforms with diverse power management mechanisms, including resource managed by firmware. Improve modularity and enable better integration with platform-specific power management, introduce support for runtime PM. Use pm_runtime_resume_and_get() and pm_runtime_put_sync() within the qcom_geni_serial_pm() callback to control resource power state transitions based on UART power state changes.

2025-07-22comedi: fix race between polling and detachingIan Abbott
syzbot reports a use-after-free in comedi in the below link, which is due to comedi gladly removing the allocated async area even though poll requests are still active on the wait_queue_head inside of it. This can cause a use-after-free when the poll entries are later triggered or removed, as the memory for the wait_queue_head has been freed. We need to check there are no tasks queued on any of the subdevices' wait queues before allowing the device to be detached by the `COMEDI_DEVCONFIG` ioctl. Tasks will read-lock `dev->attach_lock` before adding themselves to the subdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctl handler by write-locking `dev->attach_lock` before checking that all of the subdevices are safe to be deleted. This includes testing for any sleepers on the subdevices' wait queues. It remains locked until the device has been detached. This requires the `comedi_device_detach()` function to be refactored slightly, moving the bulk of it into new function `comedi_device_detach_locked()`. Note that the refactor of `comedi_device_detach()` results in `comedi_device_cancel_all()` now being called while `dev->attach_lock` is write-locked, which wasn't the case previously, but that does not matter. Thanks to Jens Axboe for diagnosing the problem and co-developing this patch.
