This patch adds a new generic streaming logic for audio over USB. It defines a model (snd_usb_endpoint) that handles everything that is related to an USB endpoint and its streaming. There are functions to activate and deactivate an endpoint (which call usb_set_interface()), and to start and stop its URBs. It also has function pointers to be called when data was received or is about to be sent, and pointer to a sync slave (another snd_usb_endpoint) that is informed when data has been received. A snd_usb_endpoint knows about its state and implements a refcounting, so only the first user will actually start the URBs and only the last one to stop it will tear them down again. With this sort of abstraction, the actual streaming is decoupled from the pcm handling, which makes the "implicit feedback" mechanisms easy to implement. In order to split changes properly, this patch only adds the new implementation but leaves the old one around, so the the driver doesn't change its behaviour. The switch to actually use the new code is submitted separately. Signed-off-by: NDaniel Mack <zonque@gmail.com> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Commit 3702b082 added a lock, but did not account for the case of SNDRV_PCM_POS_XRUN, which would get immediately overwritten.

A malicious USB device could feed in a large nr_rates value. This would cause the subsequent call to kmemdup() to allocate a smaller buffer than expected, leading to out-of-bounds access.

With some buggy devices, the usb-audio driver may give "frame xxx active" kernel messages too often. Better to keep it as debug-only using snd_printdd(), and also add the rate-limit for avoiding floods.

A malicious USB device may feed in carefully crafted min/max/res values, so that the inner loop in parse_uac2_sample_rate_range() could run for a long time or even never terminate, e.g., given max = INT_MAX. Also nr_rates could be a large integer, which causes an integer overflow in the subsequent call to kmalloc() in parse_audio_format_rates_v2(). Thus, kmalloc() would allocate a smaller buffer than expected, leading to a memory corruption. To exploit the two vulnerabilities, an attacker needs physical access to the machine to plug in a malicious USB device. This patch makes two changes. 1) The type of "rate" is changed to unsigned int, so that the loop could stop once "rate" is larger than INT_MAX. 2) Limit nr_rates to 1024.

This converts the drivers in sound/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler.

In the recent usb-audio driver, the initialization of volume ranges may be delayed when the device doesn't respond well at the probing time. But the volume quirks for certain devices are applied only in mixer_ctl_feature_info() thus only at the very first probe and will be missing when the volume range is initialized later. This patch moves the volume quirk code to be always called from the volume-range extraction (get_min_max()), so that the quirks are properly applied in the later init time.

If the device is unplugged while running, it is possible for a PCM device to be closed after the disconnect callback has returned. This means that kill_stream_urb() and disable_iso_interface() would try to access already-invalid or freed USB data structures. The function free_usb_related_resources() was intended to prevent this, but forgot to clear the affected variables.

The audio_feature_info[] array should contain all entries for UAC2_FU_*, but currently a few last entries are missing. Even though, the driver tries to probe these entries in parse_audio_feature_unit() and may access the range over the array. This patch fixes the bug by limiting the loop size properly using ARRAY_SIZE() instead of a hard-coded magic number.
