It sets up the remapping for the\noverwrite_bio but then drops it immediately without submission, causing\nwrite operations to hang.\n\nFix by adding a new invalidate_committed() continuation that submits\nthe remapped writes to the cache origin after metadata commit completes,\nwhile using the overwrite_endio hook to ensure proper completion\nsequencing. This maintains existing coherency. Also improve error\nhandling in invalidate_complete() to preserve the original error status\ninstead of using bio_io_error() unconditionally."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/md/dm-cache-target.c"], "versions": [{"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "9fa18d0b981776b190ca4632942a7c2174052b78", "status": "affected", "versionType": "git"}, {"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "ecb10c193cbebf5e6984246a9b4ff1f95d45ed87", "status": "affected", "versionType": "git"}, {"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "64d6519b00be4116d365bd31f33a5e5ce2944c1a", "status": "affected", "versionType": "git"}, {"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "b8ace9e96983abb20ccf39edce8a60f1bb0b83d8", "status": "affected", "versionType": "git"}, {"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "05798d091ebcfb6d68228890e593f209e8ac940d", "status": "affected", "versionType": "git"}, {"version": "b29d4986d0da1a27cd35917cdb433672f5c95d7f", "lessThan": "4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/md/dm-cache-target.c"], "versions": [{"version": "4.12", "status": "affected"}, {"version": "0", "lessThan": "4.12", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.175", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.141", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.91", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.33", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.10", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "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": "4.12", "versionEndExcluding": "6.1.175"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.6.141"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.12.91"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "6.18.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.12", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/9fa18d0b981776b190ca4632942a7c2174052b78"}, {"url": "https://git.kernel.org/stable/c/ecb10c193cbebf5e6984246a9b4ff1f95d45ed87"}, {"url": "https://git.kernel.org/stable/c/64d6519b00be4116d365bd31f33a5e5ce2944c1a"}, {"url": "https://git.kernel.org/stable/c/b8ace9e96983abb20ccf39edce8a60f1bb0b83d8"}, {"url": "https://git.kernel.org/stable/c/05798d091ebcfb6d68228890e593f209e8ac940d"}, {"url": "https://git.kernel.org/stable/c/4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b"}], "title": "dm cache: fix write hang in passthrough mode", "x_generator": {"engine": "bippy-1.2.0"}}}}
