Lukas Wunner	c6da541644	efi/apple-properties: Reinstate support for boolean properties ... commit 355845b738e76445c8522802552146d96cb4afa7 upstream. Since commit 4466bf8282 ("efi/apple-properties: use PROPERTY_ENTRY_U8_ARRAY_LEN"), my MacBook Pro issues a -ENODATA error when trying to assign EFI properties to the discrete GPU: pci 0000:01:00.0: assigning 56 device properties pci 0000:01:00.0: error -61 assigning properties That's because some of the properties have no value. They're booleans whose presence can be checked by drivers, e.g. "use-backlight-blanking". Commit 6e98503dba ("efi/apple-properties: Remove redundant attribute initialization from unmarshal_key_value_pairs()") employed a trick to store such booleans as u8 arrays (which is the data type used for all other EFI properties on Macs): It cleared the property_entry's "is_array" flag, thereby denoting that the value is stored inline in the property_entry. Commit 4466bf8282 erroneously removed that trick. It was probably a little fragile to begin with. Reinstate support for boolean properties by explicitly invoking the PROPERTY_ENTRY_BOOL() initializer for properties with zero-length value.

Jason Gunthorpe	537946556c	mm/gup: prevent gup_fast from racing with COW during fork ... [ Upstream commit 57efa1fe5957694fa541c9062de0a127f0b9acb0 ] Since commit 70e806e4e6 ("mm: Do early cow for pinned pages during fork() for ptes") pages under a FOLL_PIN will not be write protected during COW for fork. This means that pages returned from pin_user_pages(FOLL_WRITE) should not become write protected while the pin is active. However, there is a small race where get_user_pages_fast(FOLL_PIN) can establish a FOLL_PIN at the same time copy_present_page() is write protecting it: CPU 0 CPU 1 get_user_pages_fast() internal_get_user_pages_fast() copy_page_range() pte_alloc_map_lock() copy_present_page() atomic_read(has_pinned) == 0 page_maybe_dma_pinned() == false atomic_set(has_pinned, 1); gup_pgd_range() gup_pte_range() pte_t pte = gup_get_pte(ptep) pte_access_permitted(pte) try_grab_compound_head() pte = pte_wrprotect(pte) set_pte_at(); pte_unmap_unlock() // GUP now returns with a write protected page The first attempt to resolve this by using the write protect caused problems (and was missing a barrrier), see commit f3c64eda3e ("mm: avoid early COW write protect games during fork()") Instead wrap copy_p4d_range() with the write side of a seqcount and check the read side around gup_pgd_range(). If there is a collision then get_user_pages_fast() fails and falls back to slow GUP. Slow GUP is safe against this race because copy_page_range() is only called while holding the exclusive side of the mmap_lock on the src mm_struct.

Geert Uytterhoeven	36a237526c	efi: EFI_EARLYCON should depend on EFI ... CONFIG_EFI_EARLYCON defaults to yes, and thus is enabled on systems that do not support EFI, or do not have EFI support enabled, but do satisfy the symbol's other dependencies. While drivers/firmware/efi/ won't be entered during the build phase if CONFIG_EFI=n, and drivers/firmware/efi/earlycon.c itself thus won't be built, enabling EFI_EARLYCON does force-enable CONFIG_FONT_SUPPORT and CONFIG_ARCH_USE_MEMREMAP_PROT, and CONFIG_FONT_8x16, which is undesirable. Fix this by making CONFIG_EFI_EARLYCON depend on CONFIG_EFI. This reduces kernel size on headless systems by more than 4 KiB.

It's my first time doing something like this, I haven't included the set_fs stuff because the base branch it depends on hasn't been merged yet.

In terms of exciting features, this includes support for the Memory Tagging Extension which narrowly missed 5.9, hopefully allowing userspace to run with use-after-free detection in production on CPUs that support it. Work is ongoing to integrate the feature with KASAN for 5.11. Another change that I'm excited about (assuming they get the hardware right) is preparing the ASID allocator for sharing the CPU page-table with the SMMU. Those changes will also come in via Joerg with the IOMMU pull. We do stray outside of our usual directories in a few places, mostly due to core changes required by MTE. Although much of this has been Acked, there were a couple of places where we unfortunately didn't get any review feedback. Other than that, we ran into a handful of minor conflicts in -next, but nothing that should post any issues. Summary: - Userspace support for the Memory Tagging Extension introduced by Armv8.5.

The EFI pstore implementation relies on the 'efivars' abstraction, which encapsulates the EFI variable store in a way that can be overridden by other backing stores, like the Google SMI one. On top of that, the EFI pstore implementation also relies on the efivars.ko module, which is a separate layer built on top of the 'efivars' abstraction that exposes the [deprecated] sysfs entries for each variable that exists in the backing store. Since the efivars.ko module is deprecated, and all users appear to have moved to the efivarfs file system instead, let's prepare for its removal, by removing EFI pstore's dependency on it.

Ard Biesheuvel	762cd288fc	efi/libstub: arm32: Use low allocation for the uncompressed kernel ... Before commit d0f9ca9be1 ("ARM: decompressor: run decompressor in place if loaded via UEFI") we were rather limited in the choice of base address for the uncompressed kernel, as we were relying on the logic in the decompressor that blindly rounds down the decompressor execution address to the next multiple of 128 MiB, and decompresses the kernel there. For this reason, we have a lot of complicated memory region handling code, to ensure that this memory window is available, even though it could be occupied by reserved regions or other allocations that may or may not collide with the uncompressed image. Today, we simply pass the target address for the decompressed image to the decompressor directly, and so we can choose a suitable window just by finding a 16 MiB aligned region, while taking TEXT_OFFSET and the region for the swapper page tables into account. So let's get rid of the complicated logic, and instead, use the existing bottom up allocation routine to allocate a suitable window as low as possible, and carve out a memory region that has the right properties. Note that this removes any dependencies on the 'dram_base' argument to handle_kernel_image(), and so this is removed as well. Given that this was the only remaining use of dram_base, the code that produces it is removed entirely as well.

Ard Biesheuvel	6208857b8f	efi/libstub: arm32: Base FDT and initrd placement on image address ... The way we use the base of DRAM in the EFI stub is problematic as it is ill defined what the base of DRAM actually means. There are some restrictions on the placement of FDT and initrd which are defined in terms of dram_base, but given that the placement of the kernel in memory is what defines these boundaries (as on ARM, this is where the linear region starts), it is better to use the image address in these cases, and disregard dram_base altogether.

Lenny Szubowicz	58c909022a	efi: Support for MOK variable config table ... Because of system-specific EFI firmware limitations, EFI volatile variables may not be capable of holding the required contents of the Machine Owner Key (MOK) certificate store when the certificate list grows above some size. Therefore, an EFI boot loader may pass the MOK certs via a EFI configuration table created specifically for this purpose to avoid this firmware limitation. An EFI configuration table is a much more primitive mechanism compared to EFI variables and is well suited for one-way passage of static information from a pre-OS environment to the kernel. This patch adds initial kernel support to recognize, parse, and validate the EFI MOK configuration table, where named entries contain the same data that would otherwise be provided in similarly named EFI variables. Additionally, this patch creates a sysfs binary file for each EFI MOK configuration table entry found. These files are read-only to root and are provided for use by user space utilities such as mokutil. A subsequent patch will load MOK certs into the trusted platform key ring using this infrastructure.

Ard Biesheuvel	46908326c6	efi: efibc: check for efivars write capability ... Branden reports that commit f88814cc25 ("efi/efivars: Expose RT service availability via efivars abstraction") regresses UEFI platforms that implement GetVariable but not SetVariable when booting kernels that have EFIBC (bootloader control) enabled. The reason is that EFIBC is a user of the efivars abstraction, which was updated to permit users that rely only on the read capability, but not on the write capability. EFIBC is in the latter category, so it has to check explicitly whether efivars supports writes.
