Enforce the mmap flag rules and convert affected drivers, removing ambiguous tests shared by driver mappings and ordinary memory. - "support kselftest on nommu platform" (Hajime Tazaki): Add opt-in mmap and mremap tests for NOMMU systems. Teach the runner to avoid its fork-dependent timeout command and document the build and runtime requirements. - "mm/collapse: separate a collapse from its callers" (Kiryl Shutsemau): Separate huge-page collapse from caller policy. Replace khugepaged identity checks with explicit permissions, and separate scanning from collapse with the mmap_lock drop in one place. - "mm: implement and use vma_has_anon_rmap(), silence KCSAN" (Lorenzo Stoakes): Provide a common helper for testing whether a VMA has anonymous reverse mappings. Document the locking rules, annotate intentional concurrent reads for KCSAN, and convert the core MM callers. - "mm/sparse: remove SECTION_MARKED_PRESENT and further cleanups" (David Hildenbrand): Remove SECTION_MARKED_PRESENT in favor of the early-section flag. Simplify sparse memory initialization, section metadata handling and related PFN validity checks. - "sh: remove NUMA and SPARSEMEM support" (Mike Rapoport): Remove SuperH NUMA and SPARSEMEM support. The extra memory banks have been unusable since the NO_BOOTMEM conversion, leaving only the code and data overhead. - "mm: Unify device DAX and HugeTLB vmemmap population paths" (Muchun Song): Unify the generic device DAX and HugeTLB vmemmap population paths and shared tail-page handling. Remove the duplicate DAX machinery while retaining the powerpc radix implementation. - "kselftest: mm: fix some failure of split_huge_page_test" (Yeoreum Yun): Fix huge-page split tests racing with khugepaged recollapse. Use pagemap and page flags instead of VMA-boundary assumptions which fail when glibc has already enabled THP. - "memcg: move memcgid refcount to objcg to unpin dying memcgs" (Bingfang Guo): Let dying memcgs be freed while swapped-out shmem still holds their IDs. Move ID references to reparentable objcgs, with the necessary swap accounting and RCU lifetime changes. - "mm/truncate: fix data loss when truncating straddling large folios" (Zhang Yi): Preserve out-of-range data when truncating straddling large folios. Fix a lookup race and split-failure handling, and handle minimum folio orders for the forthcoming ext4 iomap buffered I/O path. - "mm/damon: introduce damos quota goal target metric complement flag" (SJ Park): Let DAMOS quota goals use a metric's complement, so utilization can also express free-memory goals without adding separate metrics. Add the sysfs interface, documentation and tests. - "arm64/mm: Standardize printing for pgtable entries" (Anshuman Khandual): Use the generic formatter for arm64 page-table entries, ready for future wider entries. Move the safe-PTE-update check out of the header to avoid an include cycle. - "mm: kmsan: fix iounmap metadata teardown" (Dima Koziuk): Fix KMSAN metadata leaks on iounmap and failed ioremap allocations.

Share hugetlb folio acquisition code and add a regression test for the previously fixed last-region skipping bug. - "mm/damon/core: cleanup code, reduce stack usage, and add kunit" (SJ Park): Reduce kdamond stack usage and remove unused enums. Add deterministic PSI quota-goal tests which do not depend on the machine's current memory pressure. - "mm/damon: fix the temporal goal tuner's size quota conversion" (Donggeun Yoo): Bound the temporal tuner's quota conversion to prevent overflow and zero effective quotas, which could stop schemes making progress. Add boundary tests. - "Don't use GFP_DMA when calling dma_alloc_coherent" (Baoquan He): Remove redundant GFP_DMA flags from coherent DMA allocation calls. The DMA API already selects the zone from device limits and ignores the caller's flag. - "kselftest: mm: fix intermittent failure khugepaged test" (Yeoreum Yun): Propagate child-process failures in the khugepaged tests and prevent background collapse from racing their checks.

Narrower hugetlb invalidations also spare KVM guests needless refaults: the reported Redis-in-VM P99 QPS penalty while punching holes fell from 7.09% to 1.45%. Several fixes prevent lost data or corrupted memory. Lazyfree huge-page races with mremap()/munmap() could lose data or access freed memory, and MADV_COLD could lose a concurrent write's dirty bit. Another fix prevents stale migration entries from outliving large folios.

That is fixed, along with use-after-free races in PAGEMAP_SCAN during process exit and in memory-cgroup accounting on PREEMPT_RT kernels. Other fixes stop UFFDIO_MOVE spinning forever on pinned large folios, which could wedge other memory operations, and stop mremap() leaking commit charges until allocations fail under strict overcommit. A further fix keeps userfaultfd tracking intact on neighboring mappings.

fbdev: atmel_lcdfb: fix list_first_entry() on possibly empty modelist in probe 2026-10-25T07:57:27+00:00 Wang Haoran haoranwangsec@gmail.com 2026-10-23T07:56:11+00:00 01d1204582f16e8b7bfce29648e5cf77a585d962 list_first_entry() does not return NULL on an empty list; it returns a bogus pointer computed by container_of() from the list head. atmel_lcdfb_probe() initializes info->modelist with INIT_LIST_HEAD() and later takes its first entry with list_first_entry(), assuming atmel_lcdfb_of_init() populated it. However, atmel_lcdfb_of_init() drops the return value of fb_add_videomode() — unlike every other fallible call in the same function — so if fb_add_videomode() fails (its internal kmalloc can return -ENOMEM under memory pressure or fault injection), the list stays empty while of_init() reports success. The probe path then dereferences the bogus pointer in fb_videomode_to_var(&info->var, &modelist->mode). Because the bogus pointer lands inside the contiguous fb_info allocation, this may not fault immediately; instead it silently reads adjacent memory as a struct fb_videomode and programs garbage timing parameters into the LCD controller. This was found by code audit; we do not have Atmel hardware to reproduce it. Fix this on two levels: check the return value of fb_add_videomode() in atmel_lcdfb_of_init() so the failure is propagated (root cause), and use list_first_entry_or_null() in atmel_lcdfb_probe() with a NULL check that fails probe gracefully with -EINVAL (defense in depth), consistent with the surrounding error handling which bails out to stop_clk.

fbdev: defio: assert FBINFO_VIRTFB, drop VM_IO, add VM_MIXEDMAP 2026-10-24T08:56:15+00:00 Lorenzo Stoakes (ARM) ljs@kernel.org 2026-10-13T15:04:59+00:00 19458d015fccbbf2657a8e6417bbaa915c2afdd1 Currently all drivers which use defio allocate system memory. All of them also set FBINFO_VIRTFB, other than ssd1307fb, however this driver allocates system RAM, so simply failed to set this flag when it ought to. This patch sets FBINFO_VIRTFB on ssd1307fb probe, then drops setting VM_IO in fb_deferred_io_mmap() and instead requires FBINFO_VIRTFB to be set, erroring out with a kernel warning if not. The logic requires a page from the driver and since commit 1ecbc7dd2902 ("fbdev/deferred-io: Always call get_page() for framebuffer pages") has always required it to be refcounted, so this was implicitly already the case. Finally this patch sets VM_MIXEDMAP, as the logic is mapping kernel-allocated memory so this is appropriate.

Currently all drivers which use defio allocate system memory. All of them
also set FBINFO_VIRTFB, other than ssd1307fb, however this driver allocates
system RAM, so simply failed to set this flag when it ought to.

This patch sets FBINFO_VIRTFB on ssd1307fb probe, then drops setting VM_IO
in fb_deferred_io_mmap() and instead requires FBINFO_VIRTFB to be set,
erroring out with a kernel warning if not.

The logic requires a page from the driver and since commit 1ecbc7dd2902
("fbdev/deferred-io: Always call get_page() for framebuffer pages") has
always required it to be refcounted, so this was implicitly already the
case.

Finally this patch sets VM_MIXEDMAP, as the logic is mapping
kernel-allocated memory so this is appropriate.

Pull module updates from Petr Pavlu:

 - Ignore local labels and mapping symbols during module load

   These symbols were already ignored during kallsyms address-to-symbol
   lookups. Filter them out earlier during module loading to reduce
   lookup overhead and prevent them from appearing in /proc/kallsyms.

 - Fix potentially incorrect access of SetOnce<T> when setting Rust
   module parameters.

 - Fix a potential read of an uninitialized count when printing taint
   information for unloaded modules.

 - Allocate the kmod argument array using kmalloc_array() in preparation
   for conversion to type-aware allocators.

 - Clean up includes in linux/kmod.h

   Add explicit includes of linux/umh.h to files that use usermode
   helpers. Then clean up the #include list in linux/kmod.h, notably
   removing the compatibility linux/umh.h include.

 - Remove the error-injection.h include from linux/module.h

   Add explicit includes of linux/error-injection.h to files that use
   the ALLOW_ERROR_INJECTION() macro and currently rely on it being
   provided indirectly via linux/module.h. Then remove the unnecessary
   linux/error-injection.h include from linux/module.h.

 - Replace __MODULE_STRING() with __stringify() in various drivers in
   preparation for removing the former macro.
