Vladis Dronov 836b34a935 ALSA: usb-audio: Fix double-free in error paths after snd_usb_add_audio_stream() call ... create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it. Based on a patch by Takashi Iwai <tiwai@suse.de> [Note for stable backports: this patch requires the commit 902eb7fd1e ('ALSA: usb-audio: Minor code cleanup in create_fixed_stream_quirk()')] Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1283358 Reported-by: Ralf Spenneberg <ralf@spenneberg.net> Cc: <stable@vger.kernel.org> # see the note above Signed-off-by: Vladis Dronov <vdronov@redhat.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>		2016-03-31 18:07:31 +02:00
