Before, /proc/asound looked like this: 2 [Default ]: HDSPM - RME RayDAT_f1cd85 RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18 In case of a second HDSPM card, its name would be Default_1. This is cumbersome, because the order of the cards isn't stable across reboots. To help userspace tools referring to the correct card, this commit provides a unique id for each card: 2 [HDSPMxf1cd85 ]: HDSPM - RME RayDAT_f1cd85 RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18 In this example, userspace (configuration files) would then use hw:HDSPMxf1cd85 to choose the right card. The serial is masked to 24bits, so this string is always shorter than sixteen chars. Signed-off-by:Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by:

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.

The serial number is used multiple times in hdspm.c. Since it belongs to the card, let's store it in struct hdspm and refer to it whenever necessary. Signed-off-by:

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. Suggested-by:
