Today allocation of gigantic pages in HugeTLB cannot work reliably with kexec handover (KHO): - HugeTLB allocates gigantic pages using memblock and autoscaling of KHO scratch accounts for these allocations. When gigantic pages occupy half of the memory of more, KHO fails to allocate its scratch memory. - After kexec handover, memblock allocations exclusively use KHO scratch that is not supposed to contain preserved memory. This essentially blocks preservation of HugeTLB with gigantic pages. Extend early memory pools available for KHO kernel with areas that are guaranteed not to contain preserved memory"* tag 'liveupdate-v7.3-rc1-20260823' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux: (21 commits) kho: exclude hugetlb memory from scratch size calculation memblock: add memblock_reserved_hugetlb_size() memblock: make HugeTLB bootmem allocation work with KHO memblock: always include KHO headers kho: extend scratch mm/mm_init: don't rely on memblock to get KHO scratch migratetype kho: initialize preserved memory map radix tree earlier kho: initialize kho_scratch pointer earlier in boot kho: expose kho_scratch_overlap() to kexec_handover.h kho: add kho_radix_init_tree() kho: allow destroying KHO radix tree kho: allow early-boot usage of the KHO radix tree kho: add data argument to radix walk callback kho: add callback for table pages kho: add a struct for radix callbacks kho: move all memory retrieval logic to kho_mem_retrieve() kho: store incoming radix tree in kho_in kho: disallow wide keys in radix tree kho: make radix max key width more obvious kho: generalize radix tree APIs ...

bc0f793c5c41601b273a2ca64c768adca1d447f5 - Merge patch series "kho: make boot time huge page allocation work nicely with KHO"

Tue, 04 Aug 2026 08:50:03 +0200

Merge patch series "kho: make boot time huge page allocation work nicely with KHO"Pratyush Yadav says:Gigantic huge page allocation is somewhat broken currently with KHO.First, they break scratch size accounting. Since they are allocatedusing the memblock alloc APIs, they count towards RSRV_KERN, and thisscratch size when using scratch_scale. This means if huge pages take alarge enough chunk of system memory scratch size will blow up and failto allocate.Second, scratch can not contain preserved memory, and if huge pages areallocated from scratch, they will fail to be preserved with the upcominghugetlb preservation series [0].Fix this by introducing the concept of extended scratch areas. They areareas that the kernel discovers on boot by walking the KHO preservedmemory radix tree and finding free memory ranges.[0] https://lore.kernel.org/linux-mm/20251206230222.853493-1-pratyush@kernel.org/T/#u *patches from https://patch.msgid.link/20260801084833.1897543-1-pratyush@kernel.org/ kho: generalize radix tree APIs kho: make radix max key width more obvious kho: disallow wide keys in radix tree kho: store incoming radix tree in kho_in kho: move all memory retrieval logic to kho_mem_retrieve() kho: add a struct for radix callbacks kho: add callback for table pages kho: add data argument to radix walk callback kho: allow early-boot usage of the KHO radix tree kho: allow destroying KHO radix tree kho: add kho_radix_init_tree() kho: expose kho_scratch_overlap() to kexec_handover.h kho: initialize kho_scratch pointer earlier in boot kho: initialize preserved memory map radix tree earlier mm/mm_init: don't rely on memblock to get KHO scratch migratetype kho: extend scratch memblock: always include KHO headers memblock: make HugeTLB bootmem allocation work with KHO memblock: add memblock_reserved_hugetlb_size() kho: exclude hugetlb memory from scratch size calculation List of files: /linux/kernel/liveupdate/Makefile

Sat, 01 Aug 2026 10:48:22 +0200

kho: expose kho_scratch_overlap() to kexec_handover.hSupport for discovering memory blocks with no preserved memory will beadded in coming patches. These areas will also be marked as scratch toallow allocations from them. Memblock will switch to looking through thescratch array to decide the right migratetype.Expose kho_scratch_overlap() to KHO users. Since it is now used bynon-debug code, move it out of kexec_handover_debug.c and intokexec_handover.c. Gate the overlap checks in kho_preserve_folio() andkho_preserve_pages() by IS_ENABLED(CONFIG_KEXEC_HANDOVER_DEBUG) instead.Since kexec_handover_debug.c is now empty, delete it.Add a stub for kho_scratch_overlap() to memblock tests to make sure itcompiles. It will be used in memblock by a coming commit.No functional changes.Signed-off-by: Pratyush Yadav (Google) Link: https://patch.msgid.link/20260801084833.1897543-14-pratyush@kernel.orgSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/kernel/liveupdate/Makefile

Wed, 03 Jun 2026 20:15:46 +0200

Merge patch series "liveupdate: Remove limits on sessions and files"Pasha Tatashin says:Remove the fixed limits on the number of files that can be preservedwithin a single session, and the total number of sessions managed by theLive Update Orchestrator (LUO).The core of the change is a transition from single contiguous memoryblocks for metadata serialization to a chain of linked blocks. Thisallows LUO to scale dynamically.1. ABI Evolution:- Introduced linked-block headers for both file and session serialization.- Bumped session ABI version to v4.2. Memory Management & Security:- Implemented a dynamic block allocation and reuse strategy. Blocks are allocated only when existing ones are exhausted and are reused during session/file removal cycles.- Introduced KHO_MAX_BLOCKS (10000) as a safeguard against stupid excessive allocations or corrupted cyclic lists during restore.3. Expanded Selftests:- Added new kexec-based tests verifying preservation of 2000 sessions and 500 files per session.- Added self-tests for many sessions and many files management.* patches from https://patch.msgid.link/20260603154402.468928-1-pasha.tatashin@soleen.com:liveupdate: change file_set->count type to u64 for type safetyliveupdate: avoid mixing cleanup guards with goto in luo_session_retrieve_fdliveupdate: centralize state management into struct luo_serliveupdate: register luo_ser as KHO subtreeliveupdate: Extract luo_file_deserialize_one helperliveupdate: Extract luo_session_deserialize_one helperkho: add support for linked-block serializationliveupdate: defer session block allocation and physical address settingliveupdate: Remove limit on the number of sessionsliveupdate: Remove limit on the number of files per sessionselftests/liveupdate: Test session and file limit removalselftests/liveupdate: Add stress-sessions kexec testselftests/liveupdate: Add stress-files kexec testLink: https://patch.msgid.link/20260603154402.468928-1-pasha.tatashin@soleen.comSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/kernel/liveupdate/Makefile

Wed, 03 Jun 2026 17:43:56 +0200

kho: add support for linked-block serializationIntroduce a linked-block serialization mechanism for state handover.Previously, LUO used contiguous memory blocks for serializing sessionsand files, which imposed limits on the total number of items that couldbe preserved across a live update.This commit adds the infrastructure for a more flexible, block-basedapproach where serialized data is stored in a chain of linked blocks.This is a generic KHO serialization block infrastructure that can beused by multiple subsystems.Signed-off-by: Pasha Tatashin Link: https://patch.msgid.link/20260603154402.468928-8-pasha.tatashin@soleen.comSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/kernel/liveupdate/Makefile
