2012-06-08ALSA: usb-audio: Fix substream assignmentsTakashi Iwai
In 3.5 kernel, the endpoint is assigned dynamically for the substreams, but the PCM assignment still checks the presence of the endpoint pointer. This ended up in duplicated PCM substream creations at probing time, resulting in kernel warnings like: WARNING: at fs/proc/generic.c:586 proc_register+0x169/0x1a6() Pid: 1152, comm: modprobe Not tainted 3.5.0-rc1-00110-g71fae7e #2 Call Trace: [<ffffffff8102a400>] warn_slowpath_common+0x83/0x9c [<ffffffff8102a4bc>] warn_slowpath_fmt+0x46/0x48 [<ffffffff813829ad>] ? add_preempt_count+0x39/0x3b [<ffffffff811292f0>] proc_register+0x169/0x1a6 [<ffffffff8112962e>] create_proc_entry+0x74/0x8c [<ffffffffa018eb63>] snd_info_register+0x3e/0xc3 [snd] [<ffffffffa01fde2e>] snd_pcm_new_stream+0xb1/0x404 [snd_pcm] [<ffffffffa024861f>] snd_usb_add_audio_stream+0xd2/0x230 [snd_usb_audio] [<ffffffffa0241d33>] ? snd_usb_parse_audio_format+0x252/0x34f [snd_usb_audio] [<ffffffff810d6b17>] ? kmem_cache_alloc_trace+0xab/0xbb [<ffffffffa0248c29>] snd_usb_parse_audio_interface+0x4ac/0x567 [snd_usb_audio] [<ffffffffa023f0ff>] snd_usb_create_stream+0xe9/0x125 [snd_usb_audio] [<ffffffffa023f9b1>] usb_audio_probe+0x62a/0x72c [snd_usb_audio] .....

2012-04-13ALSA: snd-usb: implement new endpoint streaming modelDaniel Mack
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: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.
