Evicting that inode\ndrops its reference to the base inode and can invoke ntfs_drop_big_inode()\nfor the base inode from within the base inode's own writeback path.\n\nIf the base inode is unlinked, ntfs_drop_big_inode() calls\ntruncate_setsize(), which waits for the inode's folio writeback to\ncomplete. The same writeback worker is responsible for completing that\nwriteback, so it waits for itself indefinitely.\n\nPrevent this self-deadlock by grabbing a reference to the base inode at the\nbeginning of ntfs_writepages() and releasing it at the end of the function.\nThis defers eviction until all bios have been submitted, allowing the wait\nfor folio writeback to complete safely."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ntfs/aops.c"],"versions":[{"version":"b041ca562526b3c4a71b41b80ba5e520eac636ad","lessThan":"5a5f877c5df7605e9bae524a25ec0df9b9cb8ea8","status":"affected","versionType":"git"},{"version":"b041ca562526b3c4a71b41b80ba5e520eac636ad","lessThan":"77dc384207d5fa63ba97c3bf3285fe1215a1cbf6","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ntfs/aops.c"],"versions":[{"version":"7.1","status":"affected"},{"version":"0","lessThan":"7.1","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.1","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.1","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5a5f877c5df7605e9bae524a25ec0df9b9cb8ea8"},{"url":"https://git.kernel.org/stable/c/77dc384207d5fa63ba97c3bf3285fe1215a1cbf6"}],"title":"ntfs: avoid self-deadlock during inode eviction","x_generator":{"engine":"bippy-1.2.0"}}}}
