2012-02-11ALSA: ice1724 - Check for ac97 to avoid kernel oopsPavel Hofman
commit e7848163aa2a649d9065f230fadff80dc3519775 upstream. Cards with identical PCI ids but no AC97 config in EEPROM do not have the ac97 field initialized. We must check for this case to avoid kernel oops.

commit 0584ffa548b6e59aceb027112f23a55f0133400e upstream. A slave-timer instance has no timer reference, and this results in NULL-dereference at stopping the timer, typically called at closing the device.

2011-04-30sound/oss: remove offset from load_patch callbacksDan Rosenberg
commit b769f49463711205d57286e64cf535ed4daf59e9 upstream. Was: [PATCH] sound/oss/midi_synth: prevent underflow, use of uninitialized value, and signedness issue The offset passed to midi_synth_load_patch() can be essentially arbitrary. If it's greater than the header length, this will result in a copy_from_user(dst, src, negative_val). While this will just return -EFAULT on x86, on other architectures this may cause memory corruption. Additionally, the length field of the sysex_info structure may not be initialized prior to its use. Finally, a signed comparison may result in an unintentionally large loop. On suggestion by Takashi Iwai, version two removes the offset argument from the load_patch callbacks entirely, which also resolves similar issues in opl3. Compile tested only. v3 adjusts comments and hopefully gets copy offsets right.

2011-02-09sound: Prevent buffer overflow in OSS load_mixer_volumesDan Rosenberg
commit d81a12bc29ae4038770e05dce4ab7f26fd5880fb upstream. The load_mixer_volumes() function, which can be triggered by unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to a buffer overflow. Because the provided "name" argument isn't guaranteed to be NULL terminated at the expected 32 bytes, it's possible to overflow past the end of the last element in the mixer_vols array. Further exploitation can result in an arbitrary kernel write (via subsequent calls to load_mixer_volumes()) leading to privilege escalation, or arbitrary kernel reads via get_mixer_levels(). In addition, the strcmp() may leak bytes beyond the mixer_vols array.

BugLink: https://launchpad.net/bugs/595482 The original reporter states that audible playback from the internal speaker is inaudible despite the hardware being properly detected.

2010-10-28ALSA: prevent heap corruption in snd_ctl_new()Dan Rosenberg
commit 5591bf07225523600450edd9e6ad258bb877b779 upstream. 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.

commit 27f7ad53829f79e799a253285318bff79ece15bd upstream. The error handling in snd_seq_oss_open() has several bad codes that do dereferecing released pointers and double-free of kmalloc'ed data.

commit f495088210c8b9e20791d995a8210170c68d2deb upstream. Fix combine_word problem where first octet is not read properly. The only affected place seems to be the INPUT_TERMINAL type. Before now, sound controls can be created with the output terminal's name which is a fallback mechanism used only for unknown input terminal types. For example, Line can wrongly appear as Speaker. After the change it should appear as Line. The side effect of this change can be that users can expect the wrong control name in their scripts or programs while now we return the correct one.

2009-09-24sound: oxygen: work around MCE when changing volumeClemens Ladisch
commit f1bc07af9a9edc5c1d4bdd971f7099316ed2e405 upstream. When the volume is changed continuously (e.g., when the user drags a volume slider with the mouse), the driver does lots of I2C writes. Apparently, the sound chip can get confused when we poll the I2C status register too much, and fails to complete a read from it. On the PCI-E models, the PCI-E/PCI bridge gets upset by this and generates a machine check exception. To avoid this, this patch replaces the polling with an unconditional wait that is guaranteed to be long enough.

commit 6ce6c473a7fd742fdb0db95841e2c4c6b37337c5 upstream. This reverts commit 7e86c0e6850504ec9516b953f316a47277825e33 ("do not overwrite EEPROM on Xonar D2/D2X") because it did not actually help with the problem. More user reports show that the overwriting of the EEPROM is not triggered by using this driver but by installing Linux, and that the installation of any other operating system (even one without any CMI8788 driver) has the same effect. In other words, the presence of this driver does not have any effect on the occurrence of the error. (So far, the available evidence seems to point to a BIOS bug.) Furthermore, it turns out that the EEPROM chip is protected against stray write commands by the command format and by requiring a separate write-enable command, so the error scenario in the previous commit (that SPI writes can be misinterpreted as an EEPROM write command) is not even theoretically possible. The mixer control that was removed as a consequence of the previous commit can only be partially emulated in userspace, which also means it cannot be seen be the in-kernel OSS API emulation, so it is better to revert that change.

2009-03-16ALSA: usb-audio - Fix non-continuous rate detectionTakashi Iwai
commit 0412558c873f716efe902b397af0653a550f7341 upstream. The detection of non-continuous rates (given via rate tables) isn't processed properly (e.g. for type II). This patch fixes and simplifies the detection code. Tested-by: Joris van Rantwijk <jorispubl@xs4all.nl> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 5370d96f85962769ea3df3a81cc885f257c51589 upstream. Incorrect variable was used to get the next sample which caused S2 to be stuck with the same value resulting in loud background noise.

2009-03-16ALSA: aw2: do not grab every saa7146 based deviceAnssi Hannula
commit e8bf069c419c1dc0657e02636441fe1179a9db14 upstream. Audiowerk2 driver snd-aw2 is bound to any saa7146 device as it does not check subsystem ids. Many DVB devices are saa7146 based, so aw2 driver grabs them as well. According to http://lkml.org/lkml/2008/10/15/311 aw2 devices have the subsystem ids set to 0, the saa7146 default. Fix conflicts with DVB devices by checking for subsystem ids = 0 specifically.

commit 32cf9a16f4af01573ddec1eb073111fc20a9d7d4 upstream. Fix the initial value for input hwport. The old value (-1) may cause Oops when an realtime MIDI byte is received before the input port is explicitly given. Instead, now it's set to the broadcasting as default.

commit 894dcd78782842924527598b0b764c9b4e679e21 upstream. For audio devices that do not have proper audio descriptors (e.g., Edirol UA-20), we use hardcoded parameters from our quirks list. However, we must still read the maximum packet size from the standard endpoint descriptor; otherwise, we might use packets that are too big and therefore rejected by the USB core.

2009-02-02sound: virtuoso: do not overwrite EEPROM on Xonar D2/D2XClemens Ladisch
commit 7e86c0e6850504ec9516b953f316a47277825e33 upstream. On the Asus Xonar D2 and D2X models, the SPI chip select signal for the fourth DAC shares its pin with the serial clock for the EEPROM that contains the PCI subdevice ID values. It appears that when DAC registers are written and some other unknown conditions occur (probably noise on the EEPROM's chip select line), the EEPROM gets overwritten with garbage, which makes it impossible to properly detect the card later. Therefore, we better avoid DAC register writes and make sure that the driver works with the DAC's registers' default values. Consequently, the sample format is now I2S instead of left-justified (no user-visible change), and the DAC's volume/mute registers cannot be used anymore (volume changes are now done by the software volume plugin).

2009-02-02ALSA: hda - Fix PCM reference NID for STAC/IDT analog outputsTakashi Iwai
commit 00a602db1ce9d61319d6f769dee206ec85f19bda upstream. The reference NID for the analog outputs of STAC/IDT codecs is set to a fixed number 0x02. But this isn't always correct and in many codecs it points to a non-existing NID. This patch fixes the initialization of the PCM reference NID taken from the actually probed DAC list.
