ALSA: opl3: Hardening for potential Spectre v1

2018-05-23T01:36:38Z

[ Upstream commit 7f054a5bee0987f1e2d4e59daea462421c76f2cb ] As recently Smatch suggested, one place in OPL3 driver may expand the array directly from the user-space value with speculation: sound/drivers/opl3/opl3_synth.c:476 snd_opl3_set_voice() warn: potential spectre issue 'snd_opl3_regmap' This patch puts array_index_nospec() for hardening against it.

Merging the HD-audio fixes back to base devel branch for further working on it.

ALSA: opl3: small array underflow

2015-03-06T12:04:42Z

There is a missing lower bound check on "pitchbend" so it means we can read up to 6 elements before the start of the opl3_note_table[] array. Thanks to Clemens Ladisch for his help with this patch. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

ALSA: seq: Define driver object in each driver

2015-02-12T13:15:54Z

This patch moves the driver object initialization and allocation to each driver's module init/exit code like other normal drivers. The snd_seq_driver struct is now published in seq_device.h, and each driver is responsible to define it with proper driver attributes (name, probe and remove) with snd_seq_driver specific attributes as id and argsize fields. The helper functions snd_seq_driver_register(), snd_seq_driver_unregister() and module_snd_seq_driver() are used for simplifying codes. Signed-off-by: Takashi Iwai

ALSA: Include linux/io.h instead of asm/io.h

2015-01-28T15:49:33Z

Nowadays it's recommended. Replace all in a shot. Signed-off-by: Takashi Iwai

ALSA: opl3: Use setup_timer() and mod_timer()

2015-01-19T10:32:26Z

No functional change, refactoring with the standard helpers. Signed-off-by: Takashi Iwai

ALSA: Drop unused name argument in snd_register_oss_device()

2014-02-12T09:58:19Z

The last argument, name, of snd_oss_register_device() is nowhere referred in the function in the current code. Let's drop it. Signed-off-by: Takashi Iwai

ALSA: Replace with IS_ENABLED()

2014-02-10T10:42:00Z

Replace the lengthy #if defined(XXX) || defined(XXX_MODULE) with the new IS_ENABLED() macro. The patch still doesn't cover all ifdefs. For example, the dependency on CONFIG_GAMEPORT is still open-coded because this also has an extra dependency on MODULE. Similarly, an open-coded ifdef in pcm_oss.c and some sequencer-related stuff are left untouched. Signed-off-by: Takashi Iwai
