If userspace then freezes reshape and\nwrites md/suspend_lo or md/suspend_hi, mddev_suspend() kills active_io\nand waits for all in-flight IO to drain.\n\nThis can deadlock: the IO needs reshape progress to continue, but the\nreshape thread is already frozen, so the active_io reference is never\ndropped and suspend never completes.\n\nraid5_prepare_suspend() already wakes wait_for_reshape for dm-raid. Do\nthe same for normal md suspend when reshape is already interrupted, so\nwaiting raid456 IO can abort, drop its reference, and let suspend\nfinish.\n\nThe mdadm test tests/25raid456-reshape-deadlock reproduces the hang."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/md/md.c"], "versions": [{"version": "714d20150ed85811193ae07a494d91f9927c590f", "lessThan": "8b6a72420821e6da2cab6a69d5233500d2698b93", "status": "affected", "versionType": "git"}, {"version": "714d20150ed85811193ae07a494d91f9927c590f", "lessThan": "ff6b93410192b812d73cc54062529715b2dc849f", "status": "affected", "versionType": "git"}, {"version": "714d20150ed85811193ae07a494d91f9927c590f", "lessThan": "8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0", "status": "affected", "versionType": "git"}, {"version": "714d20150ed85811193ae07a494d91f9927c590f", "lessThan": "cf86bb53b9c92354904a328e947a05ffbfdd1840", "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/md.c"], "versions": [{"version": "6.7", "status": "affected"}, {"version": "0", "lessThan": "6.7", "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": "6.7", "versionEndExcluding": "6.12.91"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.7", "versionEndExcluding": "6.18.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.7", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.7", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/8b6a72420821e6da2cab6a69d5233500d2698b93"}, {"url": "https://git.kernel.org/stable/c/ff6b93410192b812d73cc54062529715b2dc849f"}, {"url": "https://git.kernel.org/stable/c/8ae3e14d7f3df58f7f49c02d74344e3dcd5f84f0"}, {"url": "https://git.kernel.org/stable/c/cf86bb53b9c92354904a328e947a05ffbfdd1840"}], "title": "md: wake raid456 reshape waiters before suspend", "x_generator": {"engine": "bippy-1.2.0"}}}}
