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-rc1","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-rc1"}]}]}],"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"}}}}
