* | misc: keba: Support EEPROM sections as separate devicesGerhard Engleder2024-10-131-3/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main EEPROM of KEBA CP500 devices is divided into two sections. One section for type label data like device name, order number, serial number and so on. The second section is reserved for arbitrary data stored by the user. The two sections have a defined range. The first 3 kB for the type label and the remaining 1 kB for user data. The type label is written during production and can fill up the whole 3 kB. Thus, the range is fixed and cannot be changed dynamically. The two sections cannot be presented as NVMEM cells. A NVMEM cell is always read and written at once, because the data presented to the user can differ from the data stored in the physical NVMEM cell. Thus, NVMEM cells would lead to reading 3 kB for every type label access, even if only the device name is read. So performance would suffer. But it is also an indication that NVMEM cells are designed for small data cells within NVMEM devices. Register separate NVMEM devices for every section. This enables safe access to every section. Also different access rights are then possible.

The underlying HW protocols differ but the operations are common. The RPMB partition cannot be accessed via standard block layer, but by a set of specific RPMB commands. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage. The initial aim of this patch is to provide a simple RPMB driver interface which can be accessed by the optee driver to facilitate early RPMB access to OP-TEE OS (secure OS) during the boot time. A TEE device driver can claim the RPMB interface, for example, via rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver provides a callback to route RPMB frames to the RPMB device accessible via rpmb_route_frames(). The detailed operation of implementing the access is left to the TEE device driver itself.

When trying to remove one of the resources, vmci_resource_remove() may not remove the intended one, but the object will still be freed as in the case of the datagram type in vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource leading to a use-after-free vulnerability.

This behavior does not seem ideal because the counter being already at zero indicates a use-after-free. Furthermore, returning true by refcount_sub_and_test() in this case potentially results in a double-free done by its caller. Modify the underlying function __refcount_sub_and_test() to warn about this case as a use-after-free and have it return false to avoid the potential double-free.

* | eeprom: ee1004: Fix locking issues in ee1004_probe()Armin Wolf2024-07-311-34/+51
|/ | | | | | | | | | | | | | | | | | | | | Currently, the devres-based management of ee1004_bus_data has several issues when it comes to locking: 1. It does not call mutex_unlock() before returning an error. 2. When encountering an error, it deadlocks when trying to recursively lock a mutex. Fix this by moving the mutex-protected bus data initialization into a separate function so that devm_add_action_or_reset() is called without the mutex being held.

Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...
