+ hugetlb-dont-delete-vma_lock-in-hugetlb-madv_dontneed-processing.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: hugetlb: don't delete vma_lock in hugetlb MADV_DONTNEED processing has been added to the -mm mm-hotfixes-unstable branch. Its filename is hugetlb-dont-delete-vma_lock-in-hugetlb-madv_dontneed-processing.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Mike Kravetz <mike.kravetz(a)oracle.com> Subject: hugetlb: don't delete vma_lock in hugetlb MADV_DONTNEED processing Date: Mon, 31 Oct 2022 15:34:40 -0700 madvise(MADV_DONTNEED) ends up calling zap_page_range() to clear the page tables associated with the address range. For hugetlb vmas, zap_page_range will call __unmap_hugepage_range_final. However, __unmap_hugepage_range_final assumes the passed vma is about to be removed and deletes the vma_lock to prevent pmd sharing as the vma is on the way out. In the case of madvise(MADV_DONTNEED) the vma remains, but the missing vma_lock prevents pmd sharing and could potentially lead to issues with truncation/fault races. This issue was originally reported here [1] as a BUG triggered in page_try_dup_anon_rmap. Prior to the introduction of the hugetlb vma_lock, __unmap_hugepage_range_final cleared the VM_MAYSHARE flag to prevent pmd sharing. Subsequent faults on this vma were confused as VM_MAYSHARE indicates a sharable vma, but was not set so page_mapping was not set in new pages added to the page table. This resulted in pages that appeared anonymous in a VM_SHARED vma and triggered the BUG. Create a new routine clear_hugetlb_page_range() that can be called from madvise(MADV_DONTNEED) for hugetlb vmas. It has the same setup as zap_page_range, but does not delete the vma_lock. Also, add a new zap flag ZAP_FLAG_UNMAP to indicate an unmap call from unmap_vmas(). This is used to indicate the 'final' unmapping of a vma. The routine __unmap_hugepage_range to take a notification_needed argument. This is used to prevent duplicate notifications.

[PATCH v6] hugetlb: don't delete vma_lock in hugetlb MADV_DONTNEED processing

by Mike Kravetz

madvise(MADV_DONTNEED) ends up calling zap_page_range() to clear the page tables associated with the address range. For hugetlb vmas, zap_page_range will call __unmap_hugepage_range_final. However, __unmap_hugepage_range_final assumes the passed vma is about to be removed and deletes the vma_lock to prevent pmd sharing as the vma is on the way out. In the case of madvise(MADV_DONTNEED) the vma remains, but the missing vma_lock prevents pmd sharing and could potentially lead to issues with truncation/fault races. This issue was originally reported here [1] as a BUG triggered in page_try_dup_anon_rmap. Prior to the introduction of the hugetlb vma_lock, __unmap_hugepage_range_final cleared the VM_MAYSHARE flag to prevent pmd sharing. Subsequent faults on this vma were confused as VM_MAYSHARE indicates a sharable vma, but was not set so page_mapping was not set in new pages added to the page table. This resulted in pages that appeared anonymous in a VM_SHARED vma and triggered the BUG. Create a new routine clear_hugetlb_page_range() that can be called from madvise(MADV_DONTNEED) for hugetlb vmas. It has the same setup as zap_page_range, but does not delete the vma_lock. Also, add a new zap flag ZAP_FLAG_UNMAP to indicate an unmap call from unmap_vmas(). This is used to indicate the 'final' unmapping of a vma. The routine __unmap_hugepage_range to take a notification_needed argument. This is used to prevent duplicate notifications.

The warning was even stronger before commit 8addc2d00fe17 ("mm: do not warn on offline nodes unless the specific node is explicitly requested"). The commit softened the warning for __GFP_THISNODE. But this warning seems not quite useful because: * There is no guarantee the node is online for __GFP_THISNODE context for all the callsites. * Kernel just fails the allocation regardless the warning, and it looks all callsites handle the allocation failure gracefully. So, removing the warning seems like the good move.
