ALSA: line6: fix control and interrupt message timeouts

2021-11-26T10:58:34+00:00

commit f4000b58b64344871d7b27c05e73932f137cfef6 upstream. USB control and interrupt message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ.

ALSA: ua101: fix division by zero at probe

2021-11-26T10:58:34+00:00

commit 55f261b73a7e1cb254577c3536cef8f415de220a upstream. Add the missing endpoint max-packet sanity check to probe() to avoid division by zero in alloc_stream_buffers() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

ALSA: usb-audio: Provide quirk for Sennheiser GSP670 Headset

2021-10-27T07:32:40+00:00

commit 3c414eb65c294719a91a746260085363413f91c1 upstream. As per discussion at: https://github.com/szszoke/sennheiser-gsp670-pulseaudio-profile/issues/13 The GSP670 has 2 playback and 1 recording device that by default are detected in an incompatible order for alsa. This may have been done to make it compatible for the console by the manufacturer and only affects the latest firmware which uses its own ID. This quirk will resolve this by reordering the channels.

ALSA: usb-audio: Validate MS endpoint descriptors

2021-05-26T09:27:32+00:00

commit e84749a78dc82bc545f12ce009e3dbcc2c5a8a91 upstream. snd_usbmidi_get_ms_info() may access beyond the border when a malformed descriptor is passed. This patch adds the sanity checks of the given MS endpoint descriptors, and skips invalid ones.

ALSA: usb-audio: Add error checks for usb_driver_claim_interface() calls

2021-05-22T08:38:25+00:00

[ Upstream commit 5fb45414ae03421255593fd5556aa2d1d82303aa ] There are a few calls of usb_driver_claim_interface() but all of those miss the proper error checks, as reported by Coverity. This patch adds those missing checks. Along with it, replace the magic pointer with -1 with a constant USB_AUDIO_IFACE_UNUSED for better readability.

commit 64f40f9be14106e7df0098c427cb60be645bddb7 upstream. ToneLab EX guitar pedal device requires the same quirk like ToneLab ST for supporting the MIDI.

ALSA: usb-audio: Apply sample rate quirk to Logitech Connect

2021-04-07T10:04:21+00:00

commit 625bd5a616ceda4840cd28f82e957c8ced394b6a upstream. Logitech ConferenceCam Connect is a compound USB device with UVC and UAC. Not 100% reproducible but sometimes it keeps responding STALL to every control transfer once it receives get_freq request. This patch adds 046d:0x084c to a snd_usb_get_sample_rate_quirk list.

ALSA: usb-audio: Fix "cannot get freq eq" errors on Dell AE515 sound bar

2021-03-17T15:07:20+00:00

commit fec60c3bc5d1713db2727cdffc638d48f9c07dc3 upstream. Dell AE515 sound bar (413c:a506) spews the error messages when the driver tries to read the current sample frequency, hence it needs to be on the list in snd_usb_get_sample_rate_quirk().
