6b1842775a460245e97d36d3a67d0cfba7c4ff79 - mm/alloc_tag: clear codetag for pages allocated before page_ext initialization

Tue, 31 Mar 2026 08:13:12 +0000

mm/alloc_tag: clear codetag for pages allocated before page_ext initializationDue to initialization ordering, page_ext is allocated and initializedrelatively late during boot. Some pages have already been allocated andfreed before page_ext becomes available, leaving their codetaguninitialized.A clear example is in init_section_page_ext(): alloc_page_ext() callskmemleak_alloc(). If the slab cache has no free objects, it falls back tothe buddy allocator to allocate memory. However, at this point page_extis not yet fully initialized, so these newly allocated pages have nocodetag set. These pages may later be reclaimed by KASAN, which causesthe warning to trigger when they are freed because their codetag ref isstill empty.Use a global array to track pages allocated before page_ext is fullyinitialized. The array size is fixed at 8192 entries, and will emit awarning if this limit is exceeded. When page_ext initializationcompletes, set their codetag to empty to avoid warnings when they arefreed later.This warning is only observed with CONFIG_MEM_ALLOC_PROFILING_DEBUG=Y andmem_profiling_compressed disabled:[ 9.582133] ------------[ cut here ]------------[ 9.582137] alloc_tag was not set[ 9.582139] WARNING: ./include/linux/alloc_tag.h:164 at __pgalloc_tag_sub+0x40f/0x550, CPU#5: systemd/1[ 9.582190] CPU: 5 UID: 0 PID: 1 Comm: systemd Not tainted 7.0.0-rc4 #1 PREEMPT(lazy)[ 9.582192] Hardware name: Red Hat KVM, BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014[ 9.582194] RIP: 0010:__pgalloc_tag_sub+0x40f/0x550[ 9.582196] Code: 00 00 4c 29 e5 48 8b 05 1f 88 56 05 48 8d 4c ad 00 48 8d 2c c8 e9 87 fd ff ff 0f 0b 0f 0b e9 f3 fe ff ff 48 8d 3d 61 2f ed 03 <67> 48 0f b9 3a e9 b3 fd ff ff 0f 0b eb e4 e8 5e cd 14 02 4c 89 c7[ 9.582197] RSP: 0018:ffffc9000001f940 EFLAGS: 00010246[ 9.582200] RAX: dffffc0000000000 RBX: 1ffff92000003f2b RCX: 1ffff110200d806c[ 9.582201] RDX: ffff8881006c0360 RSI: 0000000000000004 RDI: ffffffff9bc7b460[ 9.582202] RBP: 0000000000000000 R08: 0000000000000000 R09: fffffbfff3a62324[ 9.582203] R10: ffffffff9d311923 R11: 0000000000000000 R12: ffffea0004001b00[ 9.582204] R13: 0000000000002000 R14: ffffea0000000000 R15: ffff8881006c0360[ 9.582206] FS: 00007ffbbcf2d940(0000) GS:ffff888450479000(0000) knlGS:0000000000000000[ 9.582208] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 9.582210] CR2: 000055ee3aa260d0 CR3: 0000000148b67005 CR4: 0000000000770ef0[ 9.582211] PKRU: 55555554[ 9.582212] Call Trace:[ 9.582213] [ 9.582214] ? __pfx___pgalloc_tag_sub+0x10/0x10[ 9.582216] ? check_bytes_and_report+0x68/0x140[ 9.582219] __free_frozen_pages+0x2e4/0x1150[ 9.582221] ? __free_slab+0xc2/0x2b0[ 9.582224] qlist_free_all+0x4c/0xf0[ 9.582227] kasan_quarantine_reduce+0x15d/0x180[ 9.582229] __kasan_slab_alloc+0x69/0x90[ 9.582232] kmem_cache_alloc_noprof+0x14a/0x500[ 9.582234] do_getname+0x96/0x310[ 9.582237] do_readlinkat+0x91/0x2f0[ 9.582239] ? __pfx_do_readlinkat+0x10/0x10[ 9.582240] ? get_random_bytes_user+0x1df/0x2c0[ 9.582244] __x64_sys_readlinkat+0x96/0x100[ 9.582246] do_syscall_64+0xce/0x650[ 9.582250] ? __x64_sys_getrandom+0x13a/0x1e0[ 9.582252] ? __pfx___x64_sys_getrandom+0x10/0x10[ 9.582254] ? do_syscall_64+0x114/0x650[ 9.582255] ? ksys_read+0xfc/0x1d0[ 9.582258] ? __pfx_ksys_read+0x10/0x10[ 9.582260] ? do_syscall_64+0x114/0x650[ 9.582262] ? do_syscall_64+0x114/0x650[ 9.582264] ? __pfx_fput_close_sync+0x10/0x10[ 9.582266] ? file_close_fd_locked+0x178/0x2a0[ 9.582268] ? __x64_sys_faccessat2+0x96/0x100[ 9.582269] ? __x64_sys_close+0x7d/0xd0[ 9.582271] ? do_syscall_64+0x114/0x650[ 9.582273] ? do_syscall_64+0x114/0x650[ 9.582275] ? clear_bhb_loop+0x50/0xa0[ 9.582277] ? clear_bhb_loop+0x50/0xa0[ 9.582279] entry_SYSCALL_64_after_hwframe+0x76/0x7e[ 9.582280] RIP: 0033:0x7ffbbda345ee[ 9.582282] Code: 0f 1f 40 00 48 8b 15 29 38 0d 00 f7 d8 64 89 02 48 c7 c0 ff ff ff ff c3 0f 1f 40 00 f3 0f 1e fa 49 89 ca b8 0b 01 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d fa 37 0d 00 f7 d8 64 89 01 48[ 9.582284] RSP: 002b:00007ffe2ad8de58 EFLAGS: 00000202 ORIG_RAX: 000000000000010b[ 9.582286] RAX: ffffffffffffffda RBX: 000055ee3aa25570 RCX: 00007ffbbda345ee[ 9.582287] RDX: 000055ee3aa25570 RSI: 00007ffe2ad8dee0 RDI: 00000000ffffff9c[ 9.582288] RBP: 0000000000001000 R08: 0000000000000003 R09: 0000000000001001[ 9.582289] R10: 0000000000001000 R11: 0000000000000202 R12: 0000000000000033[ 9.582290] R13: 00007ffe2ad8dee0 R14: 00000000ffffff9c R15: 00007ffe2ad8deb0[ 9.582292] [ 9.582293] ---[ end trace 0000000000000000 ]---Link: https://lore.kernel.org/20260331081312.123719-1-hao.ge@linux.devFixes: dcfe378c81f72 ("lib: introduce support for page allocation tagging")Signed-off-by: Hao Ge Suggested-by: Suren Baghdasaryan Acked-by: Suren Baghdasaryan Cc: Kent Overstreet Cc: Signed-off-by: Andrew Morton List of files: /linux/lib/alloc_tag.c

The main aim here is to be able to use the mmap write lock's lockdep state to perform various assertions regarding the locking which the VMA code requires (Lorenzo Stoakes) - "mm, swap: swap table phase II: unify swapin use" removes some old swap code (swap cache bypassing and swap synchronization) which wasn't working very well. Various other cleanups and simplifications were made. The end result is a 20% speedup in one benchmark (Kairui Song) - "enable PT_RECLAIM on more 64-bit architectures" makes PT_RECLAIM available on 64-bit alpha, loongarch, mips, parisc, and um. Various cleanups were performed along the way (Qi Zheng)* tag 'mm-stable-2026-02-11-19-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (325 commits) mm/memory: handle non-split locks correctly in zap_empty_pte_table() mm: move pte table reclaim code to memory.c mm: make PT_RECLAIM depends on MMU_GATHER_RCU_TABLE_FREE mm: convert __HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config um: mm: enable MMU_GATHER_RCU_TABLE_FREE parisc: mm: enable MMU_GATHER_RCU_TABLE_FREE mips: mm: enable MMU_GATHER_RCU_TABLE_FREE LoongArch: mm: enable MMU_GATHER_RCU_TABLE_FREE alpha: mm: enable MMU_GATHER_RCU_TABLE_FREE mm: change mm/pt_reclaim.c to use asm/tlb.h instead of asm-generic/tlb.h mm/damon/stat: remove __read_mostly from memory_idle_ms_percentiles zsmalloc: make common caches global mm: add SPDX id lines to some mm source files mm/zswap: use %pe to print error pointers mm/vmscan: use %pe to print error pointers mm/readahead: fix typo in comment mm: khugepaged: fix NR_FILE_PAGES and NR_SHMEM in collapse_file() mm: refactor vma_map_pages to use vm_insert_pages mm/damon: unify address range representation with damon_addr_range mm/cma: replace snprintf with strscpy in cma_new_area ...

Thu, 15 Jan 2026 03:15:36 +0000

alloc_tag: fix rw permission issue when handling boot parameterBoot parameters prefixed with "sysctl." are processed during the finalstage of system initialization via kernel_init()-> do_sysctl_args(). WhenCONFIG_MEM_ALLOC_PROFILING_DEBUG is enabled, the sysctl.vm.mem_profilingentry is not writable and will cause a warning.Before run_init_process(), system initialization executes in kernel threadcontext. Use current->mm to distinguish sysctl writes duringdo_sysctl_args() from user-space triggered ones.And when the proc_handler is from do_sysctl_args(), always return successbecause the same value was already set by setup_early_mem_profiling() andthis eliminates a permission denied warning.Link: https://lkml.kernel.org/r/20260115031536.164254-1-ranxiaokai627@163.comSigned-off-by: Ran Xiaokai Suggested-by: Suren Baghdasaryan Acked-by: Suren Baghdasaryan Cc: Kent Overstreet Signed-off-by: Andrew Morton List of files: /linux/lib/alloc_tag.c

alloc_tag: move memory_allocation_profiling_sysctls into .rodataRemove the change in file mode permissions done before initializing thesysctl. It is not necessary as the writing of the kernel variable will beblocked by the proc_mem_profiling_handler when writing is disallowed (alsocontrolled by mem_profiling_support).Link: https://lkml.kernel.org/r/20251215-jag-alloc_tag_const-v1-1-35ea56a1ce13@kernel.orgSigned-off-by: Joel Granados Acked-by: Suren Baghdasaryan Cc: Kent Overstreet Signed-off-by: Andrew Morton List of files: /linux/lib/alloc_tag.c
