Intermittent segfault on song change #773

Open zsitvaij opened 4 years ago

zsitvaij commented 4 years ago

Bug report

Describe the bug

MPD sometimes crashes on song change. Sometimes the same playlist runs unchanged for days without issue, other times crashes almost immediately after server starts. No local audio output, just icecast and httpd. Client used for control is ncmpc.

Expected Behavior

No segfault.

Actual Behavior

Segfault.

I have multiple outputs defined, but only icecast and vorbis httpd is enabled. I realize I have zeroconf disabled at build time, I forgot to update my config to reflect it.

This crash occurs inside libsoxr; it is hard to tell if this is a MPD bug or a libsoxr bug. Please paste a disassembly of the crashing function, at least the region around the current instruction pointer, and a dump of all registers.

MaxKellermann commented 4 years ago

libsoxr source code is very obscure and riddled with macros... shudder.... This:

   0x00007f71ab06ba30 <+112>:   vmovss (%rsi,%rax,4),%xmm0
   0x00007f71ab06ba35 <+117>:   mov    (%rdi,%rax,8),%rdx
=> 0x00007f71ab06ba39 <+121>:   vmovss %xmm0,(%rdx,%r8,1)

is from data-io.c:

    dest[i][j] = (DEINTERLEAVE_TO)*src++;

Here, dest=%rdi=0x7f719404c4d0 and i=%rax=0 but dest[0]=NULL, so it's trying to write to the NULL pointer. This pointer however is not given by MPD; it is allocated internally by libsoxr:

STATIC real * _soxr_input(rate_t * p, real const * samples, size_t n)
{
  if (p->flushing)
    return 0;
  p->samples_in += (int64_t)n;
  return fifo_write(&p->stages[0].fifo, (int)n, samples);
}

So the null pointer is generated while flushing... the code in version 0.1.2 however looked like this:

static sample_t * rate_input(rate_t * p, sample_t const * samples, size_t n)
{
  p->samples_in += n;
  return fifo_write(&p->stages[0].fifo, (int)n, samples);
}

Which means: this is a breaking libsoxr API change, but I can't find any documentation. Not even the NEWS file mentions anything related.

Bottom line: libsoxr fucked up.

MaxKellermann commented 4 years ago

This very obscure badly documented doing-everything-in-one commit broke it: https://sourceforge.net/p/soxr/code/ci/52888cd410ae356bf3aa26d8fa106754b8fd8990 Given that the code is extremely ugly, and there is no API documentation and no usable changelog, and now this crash bug, maybe the best idea would be to remove libsoxr support from MPD ... or refuse to build with 0.1.3 for now.

zsitvaij commented 4 years ago

Thanks! I'll recompile with another resampling method, I don't remember the rationale for choosing soxr in the first place.

MaxKellermann commented 4 years ago

You can switch at runtime between all resamplers that have been enabled at compile time: https://www.musicpd.org/doc/html/plugins.html#resampler-plugins

zsitvaij commented 4 years ago

I see "internal" would have worked, but I didn't have libsamplerate enabled until now, and a recompile was under a minute.

RobSykes commented 4 years ago

Looking at the backtrace above, I can see that soxr_process is being called with an input size of 502. This doesn’t seem consistent with the analysis ‘the null pointer is generated while flushing’, since when flushing, no input should be being supplied. I wonder, is it possible that MPD is attempting to reuse a soxr context without having called SoxrPcmResampler::Reset()?

MaxKellermann commented 4 years ago

Is that necessary? Where is that documented?

RobSykes commented 4 years ago

It seems so: a simple standalone test where I tried to use a soxr context for two consecutive streams (with flushing) either succeeds or fails with or without using soxr_clear respectively. However, if this is what is happening for the OP, not sure why it would be intermittent. Wondering if seamless transition between tracks with the same sample-rate (e.g. a segue) which should have no flushing, no reset/clear, might be involved here.

The soxr documentation on this is not as explicit as it might be; soxr.h has: setting `in' to NULL when no data is available nor shall be available, and soxr_clear() as: Ready for fresh signal, same config.

MaxKellermann commented 4 years ago

"not as explicit as it might be" is an understatement. The "documentation" is not only not explicit, it is also not even implicit. Nothing in these brief comments tells me that calling soxr_clear() is necessary, ever. This is the kind of thing which is utterly important to document - it is a vital part of the semantic API of a library.

Bump, if anyone can help with the following, I'd be very interested to hear: "Looking at the backtrace above, I can see that soxr_process is being called with an input size of 502.

@MaxKellermann, it would be good to be able get to the bottom of this issue—are you able to help with the above questions?

@mrusme your post was not helpful because it does not contain a backtrace. So far, we only know it's "similar" because it also crashes, but that's useless for debugging this issue.

mrusme commented 2 years ago

@MaxKellermann understood, will update MPD to the latest GitHub commit and try again with gdb/strace or similar tooling. However, if running --verbose is not helpful it might be worth increasing the verbosity in order to at least get a bit more insights out of these kind of crashes. I'd argue that not everyone using mpd is knowledgeable enough to backtrace a segfault, so maybe a little more debug output might be helpful in first place. :-)
