| | | | | | | | | | | | | We shouldn't return directly here because we're still holding the &soundcard_mutex. This bug goes all the way back to the start of git. It's strange that no one has complained about it as a runtime bug.

| * ALSA: prevent heap corruption in snd_ctl_new()Dan Rosenberg2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The snd_ctl_new() function in sound/core/control.c allocates space for a snd_kcontrol struct by performing arithmetic operations on a user-provided size without checking for integer overflow. If a user provides a large enough size, an overflow will occur, the allocated chunk will be too small, and a second user-influenced value will be written repeatedly past the bounds of this chunk. This code is reachable by unprivileged users who have permission to open a /dev/snd/controlC* device (on many distros, this is group "audio") via the SNDRV_CTL_IOCTL_ELEM_ADD and SNDRV_CTL_IOCTL_ELEM_REPLACE ioctls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error handling in snd_seq_oss_open() has several bad codes that do dereferecing released pointers and double-free of kmalloc'ed data. The object dp is release in free_devinfo() that is called via private_free callback. The rest shouldn't touch this object any more. The patch changes delete_port() to call kfree() in any case, and gets rid of unnecessary calls of destructors in snd_seq_oss_open(). Fixes CVE-2010-3080.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Line and Mic inputs cannot be used at the same time, so the driver has to automatically disable one of them if both are set. However, it forgot to notify userspace about this change, so the mixer state would be inconsistent. To fix this, check if the other control gets muted, and send a notification event in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the WM8776 chip, this driver uses a different sample format and more features than the Windows driver. When rebooting from Linux into Windows, the latter driver does not reset the chip but assumes all its registers have their default settings, so we get garbled sound or, if the output happened to be muted before rebooting, no sound. To make that driver happy, hook our driver's cleanup function into the shutdown notifier and ensure that the chip gets reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Audio Class v2 support code in 2.6.35 added checks for the bInterfaceProtocol field. However, there are devices (usually those detected by vendor-specific quirks) that do not have one of the predefined values in this field, which made the driver reject them. To fix this regression, restore the old behaviour, i.e., assume that a device with an unknown bInterfaceProtocol field (other than UAC_VERSION_2) has more or less UAC-v1-compatible descriptors.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | For devices with more than one control interface, let's assume the first one contains the audio controls. Unfortunately, there is no field in any of the descriptors to tell us whether a control interface is for audio or MIDI controls, so a better check is not easy to implement. On a composite device with audio and MIDI functions, for example, the code currently overwrites chip->ctrl_intf, causing operations on the control interface to fail if they are issued after the device probe.

That commit increased SNDRV_PCM_FORMAT_LAST as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new sticky PCM parameter introduced the delayed clean-ups of stream- and channel-id tags. In the current implementation, this check (adding dirty flag) and actual clean-ups are done only for the codec chip. However, with HD-audio architecture, multiple codecs can be on a single bus, and the controller assign stream- and channel-ids in the bus-wide. In this patch, the stream-id and channel-id are checked over all codecs connected to the corresponding bus. Together with it, the mutex is moved to struct hda_bus, as this becomes also bus-wide.
