This is correct for free pages (as defined by for_each_free_mem_pfn_range_in_zone()) because free pages in the deferred range will be initialized and released as part of the deferred init process. memblock_free_pages() is called by memblock_free_late(), which is used to free reserved ranges after memblock_free_all() has run. All pages in reserved ranges have been initialized at that point, and accordingly, those pages are not touched by the deferred init process. This means that currently, if the pages that memblock_free_late() intends to release are in the deferred range, they will never be released to the buddy allocator. They will forever be reserved. In addition, memblock_free_pages() calls kmsan_memblock_free_pages(), which is also correct for free pages but is not correct for reserved pages. KMSAN metadata for reserved pages is initialized by kmsan_init_shadow(), which runs shortly before memblock_free_all(). For both of these reasons, memblock_free_pages() should only be called for free pages, and memblock_free_late() should call __free_pages_core() directly instead. One case where this issue can occur in the wild is EFI boot on x86_64. The x86 EFI code reserves all EFI boot services memory ranges via memblock_reserve() and frees them later via memblock_free_late() (efi_reserve_boot_services() and efi_free_boot_services(), respectively). If any of those ranges happens to fall within the deferred init range, the pages will not be released and that memory will be unavailable. For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI: v6.2-rc2: Node 0, zone DMA spanned 4095 present 3999 managed 3840 Node 0, zone DMA32 spanned 246652 present 245868 managed 178867 v6.2-rc2 + patch: Node 0, zone DMA spanned 4095 present 3999 managed 3840 Node 0, zone DMA32 spanned 246652 present 245868 managed 222816 # +43,949 pages" * tag 'fixes-2023-01-14' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock: mm: Always release pages to the buddy allocator in memblock_free_late(). 2023-01-14T16:04:00+00:00 Linus Torvalds torvalds@linux-foundation.org 2023-01-14T16:04:00+00:00 urn:sha1:880ca43e5c334c32a8af125e456d1a23314aa416 Pull kernel hardening fixes from Kees Cook: - Fix CFI hash randomization with KASAN (Sami Tolvanen) - Check size of coreboot table entry and use flex-array * tag 'hardening-v6.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: kbuild: Fix CFI hash randomization with KASAN firmware: coreboot: Check size of table entry and use flex-array 2023-01-14T14:17:27+00:00 Linus Torvalds torvalds@linux-foundation.org 2023-01-14T14:17:27+00:00 urn:sha1:8b7be52f3f0d0c24ee147ba7cab6c7fa4f9bcfbb Pull module fix from Luis Chamberlain: "Just one fix for modules by Nick" * tag 'modules-6.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: kallsyms: Fix scheduling with interrupts disabled in self-test 2023-01-14T14:08:25+00:00 Linus Torvalds torvalds@linux-foundation.org 2023-01-14T14:08:25+00:00 urn:sha1:b35ad63eeccadbcc83f295a64a029f7e7188444f Pull cifs fixes from Steve French: - memory leak and double free fix - two symlink fixes - minor cleanup fix - two smb1 fixes * tag '6.2-rc3-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6: cifs: Fix uninitialized memory read for smb311 posix symlink create cifs: fix potential memory leaks in session setup cifs: do not query ifaces on smb1 mounts cifs: fix double free on failed kerberos auth cifs: remove redundant assignment to the variable match cifs: fix file info setting in cifs_open_file() cifs: fix file info setting in cifs_query_path_info() 2023-01-14T13:57:25+00:00 Linus Torvalds torvalds@linux-foundation.org 2023-01-14T13:57:25+00:00 urn:sha1:8e768130857d08a6765f3287ad3f89c1b7d50e53 Pull SCSI fixes from James Bottomley: "Two minor fixes in the hisi_sas driver which only impact enterprise style multi-expander and shared disk situations and no core changes" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: hisi_sas: Set a port invalid only if there are no devices attached when refreshing port id scsi: hisi_sas: Use abort task set to reset SAS disks when discovered
