The error path skips the out: block, which\nrestores D0 and decrements chip->num_suspended_intf.\n\nThe card stays in SNDRV_CTL_POWER_D3hot, so later control access blocks in\nsnd_power_ref_and_wait(). USB core logs an interface resume callback error.\nIt does not retry that callback, so a later callback cannot complete the\nskipped cleanup.\n\nusb_audio_suspend() increments num_suspended_intf before returning success.\nA system-resume callback must consume the system-suspend count even if a\ncomponent resume fails. Otherwise, the stranded count skews later suspend\nand resume cycles.\n\nDo not apply this cleanup to runtime-resume errors. Runtime PM can retry\n-EAGAIN or -EBUSY without another suspend callback. The count must continue\nto describe that suspended interface. Other runtime-resume errors latch\nruntime_error in the PM core and do not cause an immediate callback retry.\n\nBoth parts of the system-resume error path are longstanding. Commit\n88a8516a2128a (\"ALSA: usbaudio: implement USB autosuspend\") introduced\nerr_out past the D0 restore. Commit 862b2509d157c (\"ALSA: usb-audio: Fix\ninconsistent card PM state after resume\") later moved\nnum_suspended_intf-- into the out: block. The error path now skips both\noperations.\n\nNo third-party code is needed to reach the error path.\nsnd_usb_mixer_resume() ends in snd_usb_mixer_activate(), which returns the\nresult of usb_submit_urb() for devices that have a mixer status URB. Its\nmixer->private_resume hook can also fail through scarlett2_init_notify().\nsnd_usb_pcm_resume() issues a SET_CUR request to a UAC3 power domain. It\ncan return -EPIPE or -EIO when the device stalls the request.\n\nRoute a component error through out: only when system_suspend is nonzero.\nContinue to return runtime-resume errors through err_out. Later component\nresume stages remain skipped. The original error still reaches USB core.\nA later transfer can fail if the device did not recover.\n\nI reproduced the system-resume failure on an Audient iD14 MkI with an\nout-of-tree diagnostic mixer resume hook. An injected -EIO on the unpatched\ncore left control readers in uninterruptible sleep in\nsnd_power_ref_and_wait() until a reboot. With this patch, the same failure\nrestored control access. A second system suspend and resume also succeeded\nafter I disabled fault injection." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/usb/card.c" ], "versions": [ { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "3fa521c3c54b42e16cad8ade76551113a783752b", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "3f06f3f5b16212f180764654a9398ff5f7a855c8", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "f1c05c41d07b874635d681ae328d13ec550470c5", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "5a625fc2284e35f33693efd9534aebaca3b005d4", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "6d3e202670b819c414076a5d07dffac8a39274ad", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "6c94877b6bab9185898bcad4b082ff5592558921", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "d1f643b1c0258bd519146f7a342bbb394d413912", "status": "affected", "versionType": "git" }, { "version": "88a8516a2128a6d078a106ead48092240e8a138f", "lessThan": "1739a976312e110c93a8dee66a1cdf893a1b187e", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/usb/card.c" ], "versions": [ { "version": "2.6.39", "status": "affected" }, { "version": "0", "lessThan": "2.6.39", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.220", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.187", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.156", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.108", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.49", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.1.13", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2.3", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.3", "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": "2.6.39", "versionEndExcluding": "5.15.220" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "6.1.187" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "6.6.156" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "6.12.108" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "6.18.49" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "7.1.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "7.2.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.39", "versionEndExcluding": "7.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/3fa521c3c54b42e16cad8ade76551113a783752b" }, { "url": "https://git.kernel.org/stable/c/3f06f3f5b16212f180764654a9398ff5f7a855c8" }, { "url": "https://git.kernel.org/stable/c/f1c05c41d07b874635d681ae328d13ec550470c5" }, { "url": "https://git.kernel.org/stable/c/5a625fc2284e35f33693efd9534aebaca3b005d4" }, { "url": "https://git.kernel.org/stable/c/6d3e202670b819c414076a5d07dffac8a39274ad" }, { "url": "https://git.kernel.org/stable/c/6c94877b6bab9185898bcad4b082ff5592558921" }, { "url": "https://git.kernel.org/stable/c/d1f643b1c0258bd519146f7a342bbb394d413912" }, { "url": "https://git.kernel.org/stable/c/1739a976312e110c93a8dee66a1cdf893a1b187e" } ], "title": "ALSA: usb-audio: Complete cleanup after system-resume errors", "x_generator": { "engine": "bippy-1.2.0" } } } }
