2012-01-11ALSA: hdspm - Provide unique driver id based on card serialAdrian Knoth
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: Takashi Iwai <tiwai@suse.de>

2012-01-09ALSA: usb-audio - Avoid flood of frame-active debug messagesTakashi Iwai
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.

2012-01-08ALSA: hdspm - Refactor serial number to avoid code duplicationAdrian Knoth

2012-01-08ALSA: usb-audio: fix possible hang and overflow in ↵Xi Wang
parse_uac2_sample_rate_range() 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.
