ALSA: ua101: fix division by zero at probe

2021-10-27T06:23:30+00:00

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")).

module: remove never implemented MODULE_SUPPORTED_DEVICE

2021-03-17T20:16:18+00:00

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not. Signed-off-by: Leon Romanovsky Signed-off-by: Linus Torvalds

ALSA: ua101: Replace tasklet with work

2020-09-09T16:33:15+00:00

The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In UA101 driver, a tasklet is still used for handling the output URBs. It can be achieved gracefully with a work queued in the high-prio system workqueue, too. This patch replaces the tasklet usage in UA101 driver with a simple work.

ALSA: ua101: convert tasklets to use new tasklet_setup() API

2020-09-02T11:27:07+00:00

In preparation for unconditionally passing the struct tasklet_struct pointer to all tasklet callbacks, switch to using the new tasklet_setup() and from_tasklet() to pass the tasklet pointer explicitly.

ALSA: usb: Drop superfluous ioctl PCM ops

PCM core deals the empty ioctl field now as default(*). Let's kill the redundant lines. (*) commit fc033cbf6fb7 ("ALSA: pcm: Allow NULL ioctl ops") Link: https://lore.kernel.org/r/20191210061145.24641-22-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: ua101: Use managed buffer allocation

2019-12-11T06:25:23+00:00

Clean up the driver with the new managed buffer allocation API. The hw_free callback became superfluous and got dropped. Link: https://lore.kernel.org/r/20191209094943.14984-69-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc()

2018-07-18T06:24:29+00:00

snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with somewhat special for vmalloc handling, but in the end, this turned to just the default handler, i.e. NULL. As the situation has never changed over decades, let's rip it off. Reviewed-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
