2024-11-13ALSA: us122l: Use snd_card_free_when_closed() at disconnectionTakashi Iwai
The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses snd_card_free() at disconnection, but this waits for the close of all used fds, hence it can take long. It eventually blocks the upper layer USB ioctls, which may trigger a soft lockup. An easy workaround is to replace snd_card_free() with snd_card_free_when_closed(). This variant returns immediately while the release of resources is done asynchronously by the card device release at the last close. The loop of us122l->mmap_count check is dropped as well. The check is useless for the asynchronous operation with *_when_closed().

Implement sync, output format, and input status mixer controls, to allow the interface to be used as a straight ADAT/SPDIF (+ Headphones) I/O interface. This does not implement the matrix mixer, output gain controls, or input level meter feedback. The full mixer interface is only really usable using a dedicated userspace control app (there are too many mixer nodes for alsamixer to be usable), so for now we leave it up to userspace to directly control these features using raw USB control messages.

2024-08-12ALSA: usb-audio: Support multiple control interfacesKarol Kosik
Registering Numark Party Mix II fails with error 'bogus bTerminalLink 1'. The problem stems from the driver not being able to find input/output terminals required to configure audio streaming. The information about those terminals is stored in AudioControl Interface. Numark device contains 2 AudioControl Interfaces and the driver checks only one of them. According to the USB standard, a device can have multiple audio functions, each represented by Audio Interface Collection. Every audio function is considered to be closed box and will contain unique AudioControl Interface and zero or more AudioStreaming and MIDIStreaming Interfaces. The Numark device adheres to the standard and defines two audio functions: - MIDIStreaming function - AudioStreaming function It starts with MIDI function, followed by the audio function. The driver saves the first AudioControl Interface in `snd_usb_audio` structure associated with the entire device. It then attempts to use this interface to query for terminals and clocks. However, this fails because the correct information is stored in the second AudioControl Interface, defined in the second Audio Interface Collection. This patch introduces a structure holding association between each MIDI/Audio Interface and its corresponding AudioControl Interface, instead of relying on AudioControl Interface defined for the entire device. This structure is populated during usb probing phase and leveraged later when querying for terminals and when sending USB requests. Alternative solutions considered include: - defining a quirk for Numark where the order of interface is manually changed, or terminals are hardcoded in the driver. This solution would have fixed only this model, though it seems that device is USB compliant, and it also seems that other devices from this company may be affected. What's more, it looks like products from other manufacturers have similar problems, i.e. Rane One DJ console - keeping a list of all AudioControl Interfaces and querying all of them to find required information. That would have solved my problem and have low probability of breaking other devices, as we would always start with the same logic of querying first AudioControl Interface. This solution would not have followed the standard though. This patch preserves the `snd_usb_audio.ctrl_intf` variable, which holds the first AudioControl Interface, and uses it as a fallback when some interfaces are not parsed correctly and lack an associated AudioControl Interface, i.e., when configured via quirks.

2024-08-07ALSA: usb-audio: Accept multiple protocols in GTBsTakashi Iwai
It's valid to give different protocols via multiple GTBs; e.g. a MIDI 1.0 port is embedded in a MIDI 2.0 device that talks with MIDI 2.0 protocol. However, the current driver implementation assumes only a single protocol over the whole Endpoint, and it can't handle such a scenario. This patch changes the driver's behavior to parse GTBs to accept multiple protocols. Instead of switching to the last given protocol, it adds the protocol capability bits now. Meanwhile, the default protocol is chosen by the first given protocol in GTBs. Practically seen, this should be a minor issue, as new devices should specify the protocols properly via UMP Endpoint Info messages, so this is rather just covering a corner case.

For an invalid input value that is out of the given range, currently USB-audio driver corrects the value silently and accepts without errors. This is no wrong behavior, per se, but the recent kselftest rather wants to have an error in such a case, hence a different behavior is expected now. This patch adds a sanity check at each control put for the standard mixer types and returns an error if an invalid value is given. Note that this covers only the standard mixer types. The mixer quirks that have own control callbacks would need different coverage. Link: https://patch.msgid.link/20240806124651.28203-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2024-08-05ALSA: line6: Fix racy access to midibufTakashi Iwai
There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. This could be a cause of KMSAN warning triggered by syzkaller below (so put as reported-by here). This patch protects the midibuf call of the former code path with a spinlock for avoiding the possible races.

2024-07-31ALSA: usb-audio: Correct surround channels in UAC1 channel mapTakashi Iwai
USB-audio driver puts SNDRV_CHMAP_SL and _SR as left and right surround channels for UAC1 channel map, respectively. But they should have been SNDRV_CHMAP_RL and _RR; the current value *_SL and _SR are rather "side" channels, not "surround". I guess I took those mistakenly when I read the spec mentioning "surround left". This patch corrects those entries to be the right channels.
