efi/runtime-wrappers: factor out efi_rts_park_worker()
x86's efi_crash_gracefully_on_page_fault() ends in an infinite schedule() loop so the kworker that faulted in firmware never runs efi_rts_wq again. A later change needs the same "park this worker forever" primitive on the runtime service timeout path, so factor the loop into a shared efi_rts_park_worker() and call it from the x86 page-fault handler. No functional change. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

gpio updates for v7.3-rc1
GPIO core:
- extend the gpio-regmap abstraction layer with more features allowing users
to override configuration setting, translate register values and masks and
enable/disable interrupts
- extend GPIO kunit tests with suites verifying probe ordering by software
node devlink support and software node hogs
- shrink GPIO kunit initialization code
- coding style updates (remove commas from sentinels where applicable)
- with all users now converted treewide to using real firmware node links for
software node GPIO lookup: remove the deprecated label-matching mechanism
from from GPIO core
- drop redundant return value check of nonseekable_open() in gpiolib-cdev
- use IRQ trigger helpers where applicable
Driver updates:
- refactor error paths and logging in gpio-nomadik
- use more modern interfaces for getting resources in gpio-rockchip,
gpio-bt8xx and gpio-pca9570
- add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
- drop unused FILONOFF macro from gpio-rcar
- extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
- only enable the gpio-rtd driver by default with ARCH_REALTEK=y to avoid
bloating the build
- refactor coding style in several drivers
- use correct endianess translation in gpio-pcf85x
- add wake-up interrupt support to gpio-mvebu
- apply initial value in direction output setter in gpio-by-pinctrl
Misc:
- replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h which now
exports all the deprecated APIs
- select GPIOLIB_LEGACY in Kconfig where required treewide
- use software nodes for gpio-keys in MFD drivers
Devicetree bindings:
- describe the realtek rtd1625 GPIO controller
- document new models for gpio-pca95xx and gpio-cadence
- document new property in gpio-rockchip

x86/olpc: select GPIOLIB_LEGACY
The OLPC GPIO controller sets up a fixed number space that is used
by at least two drivers:
arch/x86/platform/olpc/olpc-xo1-sci.c: In function 'setup_ec_sci':
arch/x86/platform/olpc/olpc-xo1-sci.c:358:13: error: implicit declaration of function 'gpio_request' [-Wimplicit-function-declaration]
358 | r = gpio_request(OLPC_GPIO_ECSCI, "OLPC-ECSCI");

41 | gpio_set_value(OLPC_GPIO_MIC_AC, on);
The AMD Geode platform that this is based on is now marked as
'Orphaned' in Kconfig, and it is likely that there are no XO1
users on modern kernels, but so far there is no consensus on
removing it entirely.
Select CONFIG_GPIOLIB_LEGACY for this platform and make sure the
sound driver portion cannot be compiled without this.

x86/platform/olpc: xo15: Stop setting acpi_device_name/class()
The driver sets acpi_device_name() and acpi_device_class() which are never read afterward, so make it stop doing that and drop the symbols defined specifically for this purpose. No intentional functional impact. This will facilitate the removal of device_name and device_class from struct acpi_device_pnp in the future. Signed-off-by: Rafael J.

x86/platform/olpc: xo15: Convert ACPI driver to a platform one
In all cases in which a struct acpi_driver is used for binding a driver to an ACPI device object, a corresponding platform device is created by the ACPI core and that device is regarded as a proper representation of underlying hardware. Accordingly, a struct platform_driver should be used by driver code to bind to that device. There are multiple reasons why drivers should not bind directly to ACPI device objects [1]. Overall, it is better to bind drivers to platform devices than to their ACPI companions, so convert the olpc-xo15-sci ACPI driver to a platform one. After this change, the wakeup source added by the driver will appear under the platform device used for driver binding, but the sysfs attribute added by the driver under the ACPI companion of that device will stay there in case there are utilities in user space expecting it to be there. While this is not expected to alter functionality, it changes sysfs layout and so it will be visible to user space.

pointing to data that is invalid once the function returns.
Fix this by ensuring the GPIO reference data is not stored on stack and

x86/efi: Disable LASS while executing runtime services
Ideally, EFI runtime services should switch to kernel virtual addresses after SetVirtualAddressMap(). However, firmware implementations are known to be buggy in this regard and continue to access physical addresses. The kernel maintains a 1:1 mapping of all runtime services code and data regions to avoid breaking such firmware. LASS enforcement relies on bit 63 of the virtual address, which would block such accesses to the lower half. Unfortunately, not doing anything could lead to #GP faults when users update to a kernel with LASS enabled. One option is to use a STAC/CLAC pair to temporarily disable LASS data enforcement. However, there is no guarantee that the stray accesses would only touch data and not perform instruction fetches. Also, relying on the AC bit would depend on the runtime calls preserving RFLAGS, which is highly unlikely in practice. Instead, use the big hammer and switch off the entire LASS mechanism temporarily by clearing CR4.LASS. Runtime services are called in the context of efi_mm, which has explicitly unmapped any memory EFI isn't allowed to touch (including userspace). So, do this right after switching to efi_mm to avoid any security impact. Some runtime services can be invoked during boot when LASS isn't active. Use a global variable (similar to efi_mm) to save and restore the correct CR4.LASS state. The runtime calls are serialized with the efi_runtime_lock, so no concurrency issues are expected.

x86/efi: defer freeing of boot services memory
efi_free_boot_services() frees memory occupied by EFI_BOOT_SERVICES_CODE
and EFI_BOOT_SERVICES_DATA using memblock_free_late().
There are two issue with that: memblock_free_late() should be used for
memory allocated with memblock_alloc() while the memory reserved with
memblock_reserve() should be freed with free_reserved_area().
More acutely, with CONFIG_DEFERRED_STRUCT_PAGE_INIT=y
efi_free_boot_services() is called before deferred initialization of the
memory map is complete.
Benjamin Herrenschmidt reports that this causes a leak of ~140MB of
RAM on EC2 t3a.nano instances which only have 512MB or RAM.
If the freed memory resides in the areas that memory map for them is
still uninitialized, they won't be actually freed because
memblock_free_late() calls memblock_free_pages() and the latter skips
uninitialized pages.
Using free_reserved_area() at this point is also problematic because
__free_page() accesses the buddy of the freed page and that again might
end up in uninitialized part of the memory map.
Delaying the entire efi_free_boot_services() could be problematic
because in addition to freeing boot services memory it updates
efi.memmap without any synchronization and that's undesirable late in
boot when there is concurrency.
More robust approach is to only defer freeing of the EFI boot services
memory.
Split efi_free_boot_services() in two. First efi_unmap_boot_services()
collects ranges that should be freed into an array then
efi_free_boot_services() later frees them after deferred init is complete.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

x86/xen/pvh: Enable PAE mode for 32-bit guest only when CONFIG_X86_PAE is set
The PVH entry is available for 32-bit KVM guests, and 32-bit KVM guests do not depend on CONFIG_X86_PAE. However, mk_early_pgtbl_32() builds different pagetables depending on whether CONFIG_X86_PAE is set. Therefore, enabling PAE mode for 32-bit KVM guests without CONFIG_X86_PAE being set would result in a boot failure during CR3 loading.

x86/boot/e820: Simplify the e820__range_remove() API
Right now e820__range_remove() has two parameters to control the
E820 type of the range removed:
extern void e820__range_remove(u64 start, u64 size, enum e820_type old_type, bool check_type);
Since E820 types start at 1, zero has a natural meaning of 'no type.
Consolidate the (old_type,check_type) parameters into a single (filter_type)
parameter:
extern void e820__range_remove(u64 start, u64 size, enum e820_type filter_type);
Note that both e820__mapped_raw_any() and e820__mapped_any()
already have such semantics for their 'type' parameter, although
it's currently not used with '0' by in-kernel code.
Also, the __e820__mapped_all() internal helper already has such
semantics implemented as well, and the e820__get_entry_type() API
uses the '0' type to such effect.
This simplifies not just e820__range_remove(), and synchronizes its
use of type filters with other E820 API functions, but simplifies
usage sites as well, such as parse_memmap_one(), beyond the reduction
of the number of parameters:
- else if (from)
- e820__range_remove(start_at, mem_size, from, 1);
else
- e820__range_remove(start_at, mem_size, 0, 0);
+ e820__range_remove(start_at, mem_size, from);
The generated code gets smaller as well:
add/remove: 0/0 grow/shrink: 0/5 up/down: 0/-66 (-66)
Function old new delta
parse_memopt 112 107 -5
efi_init 1048 1039 -9
setup_arch 2719 2709 -10
e820__range_remove 283 273 -10

To end the constant struggle with space shortage on 32-bit conflicting with 64-bit's needs. - The 2 patch series "mm/swapfile.c and swap.h cleanup" from Chris Li cleans up some swap code. - The 7 patch series "selftests/mm: Fix false positives and skip unsupported tests" from Donet Tom fixes a few things in our selftests code. - The 7 patch series "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised" from David Hildenbrand "allows individual processes to opt-out of THP=always into THP=madvise, without affecting other workloads on the system". It's a long story - the [1/N] changelog spells out the considerations. - The 11 patch series "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc. - The 3 patch series "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path. - The 5 patch series "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code. - The 2 patch series "test that rmap behaves as expected" from Wei Yang adds some rmap selftests. - The 3 patch series "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers. - The 2 patch series "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues. - The 3 patch series "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages". Using these permits btrfs to account its metadata pages to the root cgroup, rather than to the cgroups of random inappropriate tasks. - The 2 patch series "mm/pageblock: improve readability of some pageblock handling" from Wei Yang provides some readability improvements to the page allocator code. - The 11 patch series "mm/damon: support ARM32 with LPAE" from SeongJae Park teaches DAMON to understand arm32 highmem. - The 4 patch series "tools: testing: Use existing atomic.h for vma/maple tests" from Brendan Jackman performs some code cleanups and deduplication under tools/testing/. - The 2 patch series "maple_tree: Fix testing for 32bit compiles" from Liam Howlett fixes a couple of 32-bit issues in tools/testing/radix-tree.c. - The 2 patch series "kasan: unify kasan_enabled() and remove arch-specific implementations" from Sabyrzhan Tasbolatov moves KASAN arch-specific initialization code into a common arch-neutral implementation. - The 3 patch series "mm: remove zpool" from Johannes Weiner removes zspool - an indirection layer which now only redirects to a single thing (zsmalloc). - The 2 patch series "mm: task_stack: Stack handling cleanups" from Pasha Tatashin makes a couple of cleanups in the fork code. - The 37 patch series "mm: remove nth_page()" from David Hildenbrand makes rather a lot of adjustments at various nth_page() callsites, eventually permitting the removal of that undesirable helper function. - The 2 patch series "introduce kasan.write_only option in hw-tags" from Yeoreum Yun creates a KASAN read-only mode for ARM, using that architecture's memory tagging feature. It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only. - The 3 patch series "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code. - The 12 patch series "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy. - The 7 patch series "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages(). - The 3 patch series "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver. - The 2 patch series "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code. - The 14 patch series "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements. This patchset itself yields a 5-20% performance benefit in some situations. - The 3 patch series "Some ptdesc cleanups" from Matthew Wilcox utilizes the new memdesc layer to clean up the ptdesc code a little. - The 3 patch series "Fix va_high_addr_switch.sh test failure" from Chunyu Hu fixes some issues in our 5-level pagetable selftesting code. - The 2 patch series "Minor fixes for memory allocation profiling" from Suren Baghdasaryan addresses a couple of minor issues in relatively new memory allocation profiling feature. - The 3 patch series "Small cleanups" from Matthew Wilcox has a few cleanups in preparation for more memdesc work. - The 2 patch series "mm/damon: add addr_unit for DAMON_LRU_SORT and DAMON_RECLAIM" from Quanmin Yan makes some changes to DAMON in furtherance of supporting arm highmem. - The 2 patch series "selftests/mm: Add -Wunreachable-code and fix warnings" from Muhammad Anjum adds that compiler check to selftests code and fixes the fallout, by removing dead code. - The 10 patch series "Improvements to Victim Process Thawing and OOM Reaper Traversal Order" from zhongjinji makes a number of improvements in the OOM killer: mainly thawing a more appropriate group of victim threads so they can release resources. - The 5 patch series "mm/damon: misc fixups and improvements for 6.18" from SeongJae Park is a bunch of small and unrelated fixups for DAMON. - The 7 patch series "mm/damon: define and use DAMON initialization check function" from SeongJae Park implement reliability and maintainability improvements to a recently-added bug fix. - The 2 patch series "mm/damon/stat: expose auto-tuned intervals and non-idle ages" from SeongJae Park provides additional transparency to userspace clients of the DAMON_STAT information. - The 2 patch series "Expand scope of khugepaged anonymous collapse" from Dev Jain removes some constraints on khubepaged's collapsing of anon VMAs.

Move startup code out of the __head section, now that this no longer has
a special significance. Move everything into .text or .init.text as
appropriate, so that startup code is not kept around unnecessarily.

objtool: Validate kCFI calls
Validate that all indirect calls adhere to kCFI rules. Notably doing nocfi indirect call to a cfi function is broken. Apparently some Rust 'core' code violates this and explodes when ran with FineIBT. All the ANNOTATE_NOCFI_SYM sites are prime targets for attackers. - runtime EFI is especially henous because it also needs to disable IBT. Basically calling unknown code without CFI protection at runtime is a massice security issue. - Kexec image handover; if you can exploit this, you get to keep it :-) Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Acked-by: Josh Poimboeuf <jpoimboe@kernel.org> Acked-by: Sean Christopherson <seanjc@google.com> Link: https://lkml.kernel.org/r/20250714103441.496787279@infradead.org |

x86/sev: Let sev_es_efi_map_ghcbs() map the CA pages too
OVMF EFI firmware needs access to the CA page to do SVSM protocol calls. For example, when the SVSM implements an EFI variable store, such calls will be necessary. So add that to sev_es_efi_map_ghcbs() and also rename the function to reflect the additional job it is doing now.
