* firmware/sysfb: Disable sysfb for firmware buffers with unknown parentThomas Zimmermann2024-10-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit ad604f0a4c040dcb8faf44dc72db25e457c28076 upstream. The sysfb framebuffer handling only operates on graphics devices that provide the system's firmware framebuffer. If that device is not known, assume that any graphics device has been initialized by firmware. Fixes a problem on i915 where sysfb does not release the firmware framebuffer after the native graphics driver loaded.

* efistub/tpm: Use ACPI reclaim memory for event log to avoid corruptionArd Biesheuvel2024-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 77d48d39e99170b528e4f2e9fc5d1d64cdedd386 upstream. The TPM event log table is a Linux specific construct, where the data produced by the GetEventLog() boot service is cached in memory, and passed on to the OS using an EFI configuration table. The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY instead, which is always treated as reserved by the E820 conversion logic.

* firmware: qcom: scm: Disable SDI and write no dump to dump modeMukesh Ojha2024-10-041-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 79cb2cb8d89b7eca87e8dac031dadea4aeafeaa7 ] SDI is enabled for most of the Qualcomm SoCs and as per commit ff4aa3bc9825 ("firmware: qcom_scm: disable SDI if required") it was recommended to disable SDI by mentioning it in device tree to avoid hang during watchdog or during reboot. However, for some cases if download mode tcsr register already configured from boot firmware to collect dumps and if SDI is disabled via means of mentioning it in device tree we could still end up with dump collection. Disabling SDI alone is not completely enough to disable dump mode and we also need to zero out the bits download bits from tcsr register. Current commit now, unconditionally call qcom_scm_set_download_mode() based on download_mode flag, at max if TCSR register is not mentioned or available for a SoC it will fallback to legacy way of setting download mode through command which may be no-ops or return error in case current firmware does not implements QCOM_SCM_INFO_IS_CALL_AVAIL so, at worst it does nothing if it fails. It also does to call SDI disable call if dload mode is disabled, which looks fine to do as intention is to disable dump collection even if system crashes.

* firmware: cs_dsp: Don't allow writes to read-only controlsRichard Fitzgerald2024-09-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 62412a9357b16a4e39dc582deb2e2a682b92524c ] Add a check to cs_dsp_coeff_write_ctrl() to abort if the control is not writeable. The cs_dsp code originated as an ASoC driver (wm_adsp) where all controls were exported as ALSA controls. It relied on ALSA to enforce the read-only permission. Now that the code has been separated from ALSA/ASoC it must perform its own permission check. This isn't currently causing any problems so there shouldn't be any need to backport this. If the client of cs_dsp exposes the control as an ALSA control, it should set permissions on that ALSA control to protect it. The few uses of cs_dsp_coeff_write_ctrl() inside drivers are for writable controls.

| | | | | | | | | | | | | | | | | | | | | | commit 9960085a3a82c58d3323c1c20b991db6045063b0 upstream. Currently get_wq_ctx() is wrongly configured as a standard call. When two SMC calls are in sleep and one SMC wakes up, it calls get_wq_ctx() to resume the corresponding sleeping thread. But if get_wq_ctx() is interrupted, goes to sleep and another SMC call is waiting to be allocated a waitq context, it leads to a deadlock. To avoid this get_wq_ctx() must be an atomic call and can't be a standard SMC call. Hence mark get_wq_ctx() as a fast call.

* video/aperture: optionally match the device in sysfb_disable()Alex Deucher2024-09-041-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b49420d6a1aeb399e5b107fc6eb8584d0860fbd7 upstream. In aperture_remove_conflicting_pci_devices(), we currently only call sysfb_disable() on vga class devices. This leads to the following problem when the pimary device is not VGA compatible: 1. A PCI device with a non-VGA class is the boot display 2. That device is probed first and it is not a VGA device so sysfb_disable() is not called, but the device resources are freed by aperture_detach_platform_device() 3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable() 4. NULL pointer dereference via sysfb_disable() since the resources have already been freed by aperture_detach_platform_device() when it was called by the other device. Fix this by passing a device pointer to sysfb_disable() and checking the device to determine if we should execute it or not. v2: Fix build when CONFIG_SCREEN_INFO is not set v3: Move device check into the mutex Drop primary variable in aperture_remove_conflicting_pci_devices() Drop __init on pci sysfb_pci_dev_is_enabled() Fixes: 5ae3716cfdcd ("video/aperture: Only remove sysfb on the default vga pci device") Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Helge Deller <deller@gmx.de> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240821191135.829765-1-alexander.deucher@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

For ADSP2 and Halo Core the equivalent struct is wmfw_adsp2_sizes, which is 4 bytes longer. So the length check didn't guarantee that there are enough bytes in the firmware buffer for a header with wmfw_adsp2_sizes. This patch splits the length check into three separate parts. Each of the wmfw_header, wmfw_adsp?_sizes and wmfw_footer are checked separately before they are used.

In the former case, the underlying memory containing the kernel's view of the EFI memory map (which may be heavily modified by the kernel itself on x86) is not modified at all, and the only thing that changes is the virtual mapping of this memory, which is different between early and late boot. In the latter case, an entirely new allocation is created that carries a new, updated version of the kernel's view of the EFI memory map. When installing this new version, the old version will no longer be referenced, and if the memory was allocated by the kernel, it will leak unless it gets freed. The logic that implements this freeing currently lives on the code path that is shared between these two use cases, but it should only apply to the latter. So move it to the correct spot. While at it, drop the dummy definition for non-x86 architectures, as that is no longer needed.

When running with kCFI enabled, the compiler will require the target of any indirect call to be type annotated. Given that the EFI runtime services prototypes and calling convention are governed by the EFI spec, not the Linux kernel, adding such type annotations for firmware routines is infeasible, and so the compiler must be informed that prototype validation should be omitted. Add the __nocfi annotation at the appropriate places in the EFI runtime wrapper code to achieve this. Note that this currently only affects 32-bit ARM, given that other architectures that support both kCFI and EFI use an asm wrapper to call EFI runtime services, and this hides the indirect call from the compiler.

When booting in EFI mode, it is the firmware's job to ensure that the chosen range does not conflict with any memory reservations that it knows about, and this is trivially achieved by using the firmware's memory allocation APIs. That leaves reservations specified on the command line, though, which the firmware knows nothing about, as these regions have no other special significance to the platform. Since commit a1b87d54f4e4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot") these reservations are not taken into account when randomizing the physical placement, which may result in conflicts where the memory cannot be reserved by the kernel proper because its own executable image resides there. To avoid having to duplicate or reuse the existing complicated logic, disable physical KASLR entirely when such overrides are specified. These are mostly diagnostic tools or niche features, and physical KASLR (as opposed to virtual KASLR, which is much more important as it affects the memory addresses observed by code executing in the kernel) is something we can live without.

Remove redundant variables. Note: This commit changes the coverage for some objects: - include arch/mips/vdso/vdso-image.o into UBSAN, GCOV, KCOV - include arch/sparc/vdso/vdso-image-*.o into UBSAN - include arch/sparc/vdso/vma.o into UBSAN - include arch/x86/entry/vdso/extable.o into KASAN, KCSAN, UBSAN, GCOV, KCOV - include arch/x86/entry/vdso/vdso-image-*.o into KASAN, KCSAN, UBSAN, GCOV, KCOV - include arch/x86/entry/vdso/vdso32-setup.o into KASAN, KCSAN, UBSAN, GCOV, KCOV - include arch/x86/entry/vdso/vma.o into GCOV, KCOV - include arch/x86/um/vdso/vma.o into KASAN, GCOV, KCOV I believe these are positive effects because all of them are kernel space objects.

No new features, patchset either fixes or fortifies existing code. Patchset starts off with a fix for debugbility on ICL+ platforms which I have forgotten to fixup when providing support for these initially. The next two address copier module initialization, most importantly, silence the gcc 'field-spanning write' false-positive. The following four: 6/13 ASoC: Intel: avs: Replace risky functions with safer variants 7/13 ASoC: Intel: avs: Fix potential integer overflow 8/13 ASoC: Intel: avs: Test result of avs_get_module_entry() 9/13 ASoC: Intel: avs: Remove dead code address problems found out by Coverity static analysis tool. The last two worth mentioning are: recommendation from the firmware team to wake subsystem from D0ix when starting any pipeline -and- shielding against invalid period/buffer sizes. Audio format shall be taken into consideration when calculating either of these.
