For this bug, jbd2_journal_restart() is\ncalled by ocfs2_split_extent() during defragmenting.\n\nHow to fix\n\nFor ocfs2_split_extent() can handle journal operations totally by itself. \nCaller doesn't need to call journal access/dirty pair, and caller only\nneeds to call journal start/stop pair. The fix method is to remove\njournal access/dirty from __ocfs2_move_extent().\n\nThe discussion for this patch:\nhttps://oss.oracle.com/pipermail/ocfs2-devel/2023-February/000647.html" } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/ocfs2/move_extents.c" ], "versions": [ { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "5f43d34a51ed30e6a60f7e59d224a63014fe2cd5", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "7f3b1c28e2908755fb248d3ee8ff56826f2387db", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "669134a66d37258e1c4a5cfbd5b82f547ae30fca", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "2c559b3ba8e0b9e3c4bb08159a28ccadc698410f", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "33665d1042666f2e5c736a3df1f453e31f030663", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "8163ea90d89b7012dd1fa4b28edf5db0c641eca7", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "590507ebabd33cd93324c04f9a5538309a5ba934", "status": "affected", "versionType": "git" }, { "version": "8f603e567aa7a243e68ca48b4f105b990851360f", "lessThan": "60eed1e3d45045623e46944ebc7c42c30a4350f0", "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/ocfs2/move_extents.c" ], "versions": [ { "version": "3.0", "status": "affected" }, { "version": "0", "lessThan": "3.0", "status": "unaffected", "versionType": "semver" }, { "version": "4.14.308", "lessThanOrEqual": "4.14.*", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.276", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.235", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.173", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.99", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.16", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.2.3", "lessThanOrEqual": "6.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.3", "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": "3.0", "versionEndExcluding": "4.14.308" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "4.19.276" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "5.4.235" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "5.10.173" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "5.15.99" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "6.1.16" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "6.2.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.0", "versionEndExcluding": "6.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/5f43d34a51ed30e6a60f7e59d224a63014fe2cd5" }, { "url": "https://git.kernel.org/stable/c/7f3b1c28e2908755fb248d3ee8ff56826f2387db" }, { "url": "https://git.kernel.org/stable/c/669134a66d37258e1c4a5cfbd5b82f547ae30fca" }, { "url": "https://git.kernel.org/stable/c/2c559b3ba8e0b9e3c4bb08159a28ccadc698410f" }, { "url": "https://git.kernel.org/stable/c/33665d1042666f2e5c736a3df1f453e31f030663" }, { "url": "https://git.kernel.org/stable/c/8163ea90d89b7012dd1fa4b28edf5db0c641eca7" }, { "url": "https://git.kernel.org/stable/c/590507ebabd33cd93324c04f9a5538309a5ba934" }, { "url": "https://git.kernel.org/stable/c/60eed1e3d45045623e46944ebc7c42c30a4350f0" } ], "title": "ocfs2: fix defrag path triggering jbd2 ASSERT", "x_generator": { "engine": "bippy-1.2.0" } } } }
