Because of a typo in referencing the input array in snd_pcm_ladspa_allocate_memory(), ladpsa PCM plugin may cause a segfault at prepare when input and and output channels are different: #0 0x00007ffff78623ef in snd_pcm_ladspa_allocate_memory (pcm=0x626fa0, pcm=0x626fa0, pcm=0x626fa0, ladspa=0x621ad0) at pcm_ladspa.c:753 #1 snd_pcm_ladspa_init (pcm=0x626fa0) at pcm_ladspa.c:834 #2 0x00007ffff7842946 in snd_pcm_plugin_prepare (pcm=0x626fa0) at pcm_plugin.c:171 #3 0x00007ffff784290f in snd_pcm_plugin_prepare (pcm=0x62c760) at pcm_plugin.c:162 #4 0x000000000040256a in ?? () #5 0x00007ffff7222ec5 in __libc_start_main (main=0x401d80,a argc=4, argv=0x7fffffffde28, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fffffffde18) at libc-start.c:287 #6 0x0000000000402fdd in ?? () This patch corrects the wrong reference. Reported-and-tested-by: Andreas Hartmann <mail@andreashartmann.eu> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
