This causes page cache operations to\nhang waiting for the writeback flag.  For example,\ntruncate_inode_pages_final(), which is called via nilfs_evict_inode() when\nan inode is evicted from memory, will hang.\n\nSecond, the NILFS_I_COLLECTED flag set on normal inodes remain uncleared. \nAs a result, if the next log write involves checkpoint creation, that's\nfine, but if a partial log write is performed that does not, inodes with\nNILFS_I_COLLECTED set are erroneously removed from the \"sc_dirty_files\"\nlist, and their data and b-tree blocks may not be written to the device,\ncorrupting the block mapping.\n\nFix these issues by uniformly calling nilfs_segctor_abort_construction()\non failure of each step in the loop in nilfs_segctor_do_construct(),\nhaving it clean up logs and segment usages according to progress, and\ncorrecting the conditions for calling nilfs_redirty_inodes() to ensure\nthat the NILFS_I_COLLECTED flag is cleared."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/nilfs2/segment.c"],"versions":[{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"40a2757de2c376ef8a08d9ee9c81e77f3c750adf","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"036441e8438b29111fa75008f0ce305fb4e83c0a","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"efdde00d4a1ef10bb71e09ebc67823a3d3ad725b","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"3e349d7191f0688fc9808ef24fd4e4b4ef5ca876","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"30562eff4a6dd35c4b5be9699ef61ad9f5f20a06","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"0a1a961bde4351dc047ffdeb2f1311ca16a700cc","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"74866c16ea2183f52925fa5d76061a1fe7f7737b","status":"affected","versionType":"git"},{"version":"a694291a6211537189c6080f77f63cdabfc9b63e","lessThan":"6576dd6695f2afca3f4954029ac4a64f82ba60ab","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/nilfs2/segment.c"],"versions":[{"version":"2.6.33","status":"affected"},{"version":"0","lessThan":"2.6.33","status":"unaffected","versionType":"semver"},{"version":"4.19.322","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.284","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.226","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.167","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.110","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.51","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.10","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","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":"2.6.33","versionEndExcluding":"4.19.322"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"5.4.284"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"5.10.226"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"5.15.167"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"6.1.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"6.6.51"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"6.10.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.33","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/40a2757de2c376ef8a08d9ee9c81e77f3c750adf"},{"url":"https://git.kernel.org/stable/c/036441e8438b29111fa75008f0ce305fb4e83c0a"},{"url":"https://git.kernel.org/stable/c/efdde00d4a1ef10bb71e09ebc67823a3d3ad725b"},{"url":"https://git.kernel.org/stable/c/3e349d7191f0688fc9808ef24fd4e4b4ef5ca876"},{"url":"https://git.kernel.org/stable/c/30562eff4a6dd35c4b5be9699ef61ad9f5f20a06"},{"url":"https://git.kernel.org/stable/c/0a1a961bde4351dc047ffdeb2f1311ca16a700cc"},{"url":"https://git.kernel.org/stable/c/74866c16ea2183f52925fa5d76061a1fe7f7737b"},{"url":"https://git.kernel.org/stable/c/6576dd6695f2afca3f4954029ac4a64f82ba60ab"}],"title":"nilfs2:
