2022-09-22efi: libstub: check Shim mode using MokSBStateRTArd Biesheuvel1-4/+4
We currently check the MokSBState variable to decide whether we should treat UEFI secure boot as being disabled, even if the firmware thinks otherwise. This is used by shim to indicate that it is not checking signatures on boot images. In the kernel, we use this to relax lockdown policies. However, in cases where shim is not even being used, we don't want this variable to interfere with lockdown, given that the variable may be non-volatile and therefore persist across a reboot. This means setting it once will persistently disable lockdown checks on a given system. So switch to the mirrored version of this variable, called MokSBStateRT, which is supposed to be volatile, and this is something we can check.

2022-09-22efi: x86: Wipe setup_data on pure EFI bootArd Biesheuvel1-0/+7
When booting the x86 kernel via EFI using the LoadImage/StartImage boot services [as opposed to the deprecated EFI handover protocol], the setup header is taken from the image directly, and given that EFI's LoadImage has no Linux/x86 specific knowledge regarding struct bootparams or struct setup_header, any absolute addresses in the setup header must originate from the file and not from a prior loading stage. Since we cannot generally predict where LoadImage() decides to load an image (*), such absolute addresses must be treated as suspect: even if a prior boot stage intended to make them point somewhere inside the [signed] image, there is no way to validate that, and if they point at an arbitrary location in memory, the setup_data nodes will not be covered by any signatures or TPM measurements either, and could be made to contain an arbitrary sequence of SETUP_xxx nodes, which could interfere quite badly with the early x86 boot sequence. (*) Note that, while LoadImage() does take a buffer/size tuple in addition to a device path, which can be used to provide the image contents directly, it will re-allocate such images, as the memory footprint of an image is generally larger than the PE/COFF file representation.

A race condition may occur if the user calls close() on another thread during a write() operation on the device node of the efi capsule. This is a race condition that occurs between the efi_capsule_write() and efi_capsule_flush() functions of efi_capsule_fops, which ultimately results in UAF. So, the page freeing process is modified to be done in efi_capsule_release() instead of efi_capsule_flush().

2022-08-25efi: libstub: Disable struct randomizationArd Biesheuvel1-0/+7
The EFI stub is a wrapper around the core kernel that makes it look like a EFI compatible PE/COFF application to the EFI firmware. EFI applications run on top of the EFI runtime, which is heavily based on so-called protocols, which are struct types consisting [mostly] of function pointer members that are instantiated and recorded in a protocol database. These structs look like the ideal randomization candidates to the randstruct plugin (as they only carry function pointers), but of course, these protocols are contracts between the firmware that exposes them, and the EFI applications (including our stubbed kernel) that invoke them. This means that struct randomization for EFI protocols is not a great idea, and given that the stub shares very little data with the core kernel that is represented as a randomizable struct, we're better off just disabling it completely here.

2022-08-23firmware: arm_scmi: Fix the asynchronous reset requestsCristian Marussi1-2/+2
SCMI Reset protocol specification allows the asynchronous reset request only when an autonomous reset action is specified. Reset requests based on explicit assert/deassert of signals should not be served asynchronously. Current implementation will instead issue an asynchronous request in any case, as long as the reset domain had advertised to support asynchronous resets. Avoid requesting the asynchronous resets when the reset action is not of the autonomous type, even if the target reset domain does, in general, support the asynchronous requests.

It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path.

2022-07-10efi: Fix efi_power_off() not being run before acpi_power_off() when necessaryHans de Goede1-10/+11
Commit 98f30d0ecf79 ("ACPI: power: Switch to sys-off handler API") switched the ACPI sleep code from directly setting the old global pm_power_off handler to using the new register_sys_off_handler() mechanism with a priority of SYS_OFF_PRIO_FIRMWARE. This is a problem when the old global pm_power_off handler would later be overwritten, such as done by the late_initcall(efi_shutdown_init): if (efi_poweroff_required()) pm_power_off = efi_power_off; The old global pm_power_off handler gets run with a priority of SYS_OFF_PRIO_DEFAULT which is lower then SYS_OFF_PRIO_FIRMWARE, causing acpi_power_off() to run first, changing the behavior from before the ACPI sleep code switched to the new register_sys_off_handler(). Switch the registering of efi_power_off over to register_sys_off_handler() with a priority of SYS_OFF_PRIO_FIRMWARE + 1 so that it will run before acpi_power_off() as before. Note since the new sys-off-handler code will try all handlers in priority order, there is no more need for the EFI code to store and call the original pm_power_off handler.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm SCMI updates for v5.20 The main additions this time around are: 1. The capability to trace full SCMI message headers and payloads. The recent unearthing of chain of old firmware issues motivated this effort so that it is easier to trace them and debug quicker than it took this time around in absence of such tracing. 2. SCMI System power control driver to handle platform's requests for a graceful shutdown. Though the system power control protocol has been around since the begining of SCMI, it lacked the timeout information that was added in SCMI v3.1 that enables kernel to take appropriate action within the timeout and doesn't have to rely on any other user inputs(which was blocking factor for addition of this driver earlier) 3. Support for SCMI Power Capping protocol that was introduced in SCMI v3.1 This protocol is intended for controlling and monitoring the power consumption of power capping domains. The firmware also provides the hierarchy of powercap domains by providing parent domain information.

2022-07-04firmware: arm_scmi: Generalize the fast channel supportCristian Marussi3-171/+231
Generalize existing fast channel support used in the perf protocol and make it available to possibly any protocol refactoring the common code into a couple of new scmi_proto_helpers_ops routines. Make perf protocol use this new infrastructure. No functional change.

2022-07-04firmware: arm_scmi: Add SCMI System Power Control driverCristian Marussi3-0/+375
Add an SCMI System Power control driver to handle platform's requests carried by SYSTEM_POWER_STATE_NOTIFIER notifications: such platform requested system-wide power state transitions are handled accordingly, gracefully or forcefully, depending on the notifications' message flags. Graceful requests are relayed to userspace using the same Kernel API used to handle ACPI Shutdown bus events.
