The fix for the racy writes and ioctls to sequencer widened the application of client->ioctl_mutex to the whole write loop. Although it does unlock/relock for the lengthy operation like the event dup, the loop keeps the ioctl_mutex for the whole time in other situations. This may take quite long time if the user-space would give a huge buffer, and this is a likely cause of some weird behavior spotted by syzcaller fuzzer. This patch puts a simple workaround, just adding a mutex break in the loop when a large number of events have been processed. This shouldn't hit any performance drop because the threshold is set high enough for usual operations.

ALSA: firewire-lib: fix initial value of data block count for IR context without CIP_DBC_IS_END_EVENT For IR context, ALSA IEC 61883-1/6 engine uses initial value of data block counter as UINT_MAX, to detect first isochronous packet in the middle of packet streaming. At present, when CIP_DBC_IS_END_EVENT is not used (i.e. for drivers except for ALSA fireworks driver), the initial value is used as is for tracepoints event. However, the engine can detect the value of dbc field in the payload of first isochronous packet and the value should be assigned to the event. This commit fixes the bug.

firewire-motu: fix wrong reference count for stream functionality at error path of rawmidi interface In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA firewire-motu driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count. This commit fixes the bug. Fixes: 8edc56ec ("ALSA: firewire-motu: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks") Signed-off-by:

Along with the recent fix for the races of snd_hdac_refresh_widgets() it turned out that the instantiation of widgets sysfs at snd_hdac_sysfs_reinit() could cause a race. The race itself was already covered later by extending the mutex protection range, the commit 98482377 ("ALSA: hda: Fix widget_mutex incomplete protection"), but this also indicated that the call of *_reinit() is basically superfluous, as the widgets shall be created sooner or later from snd_hdac_device_register(). This patch removes the redundant call of snd_hdac_sysfs_reinit() at first. By this removal, the sysfs argument itself in snd_hdac_refresh_widgets() becomes superfluous, too, because the only case sysfs=false is always with codec->widgets=NULL. So, we drop this redundant argument as well. Signed-off-by:

Extension Unit (XU) is used to have a compatible layout with Processing Unit (PU) on UAC1, and the usb-audio driver code assumed it for parsing the descriptors. Meanwhile, on UAC2, XU became slightly incompatible with PU; namely, XU has a one-byte bmControls bitmap while PU has two bytes bmControls bitmap. This incompatibility results in the read of a wrong address for the last iExtension field, which ended up with an incorrect string for the mixer element name, as recently reported for Focusrite Scarlett 18i20 device. This patch corrects this misalignment by introducing a couple of new macros and calling them depending on the descriptor type.
