The writeback path\nmay update mapping pairs and call ntfs_attrlist_update(), which\nunconditionally calls ntfs_attr_iget() for the same $ATTRIBUTE_LIST fake\ninode. VFS then finds the I_FREEING inode and waits for eviction to finish,\nbut the current task is still inside that eviction path, causing a\nself-deadlock in find_inode().\n\nFix this by mirroring the teardown guard used by __ntfs_write_inode():\nonce SB_ACTIVE has been cleared, do not try to iget the attribute-list\nfake inode. Return -EIO so teardown aborts the update instead of waiting on\nthe inode it is evicting."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ntfs/attrlist.c"],"versions":[{"version":"495e90fa334828d4119061e2726af51d0a0fb4ed","lessThan":"d5379035355c0dcb1e92a2544d40f48441e1d637","status":"affected","versionType":"git"},{"version":"495e90fa334828d4119061e2726af51d0a0fb4ed","lessThan":"0ebe8f625ab0520217a425d7cd366e4670484941","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/attrlist.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/d5379035355c0dcb1e92a2544d40f48441e1d637"},{"url":"https://git.kernel.org/stable/c/0ebe8f625ab0520217a425d7cd366e4670484941"}],"title":"ntfs: fail attrlist updates when the superblock is inactive","x_generator":{"engine":"bippy-1.2.0"}}}}
