Comment 1 Felix Palmen 2022-07-19 12:02:37 UTC

I'm running it myself on 13.1-RELEASE without issues, but amd64, so this is probably an i386-specific issue.

It might take some time, but I'll try to reproduce it on i386 soon!

Comment 2 Felix Palmen 2022-07-20 17:19:52 UTC

Well, unfortunately, I can't reproduce. Just tested on an old i386 machine, it starts fine, SIP registration works, incoming calls are signalled...

(In reply to Felix Palmen from comment #2)
Well, unfortunately I can reproduce it. I did run a new poudriere build which completed.

Then I removed the old linphone installation from the i386 and any leftovers in user directories. find / -name "*linphone" showed no output.

Then I did pkg install -y linphone |% tee linphone_first_run
this segfaulted again with the same output as yesterday but this first line:

2022-07-21 09:26:14:744 bctbx-error-bctbx_file_open: Error open No such file or directory

Awaiting instructions for testing.

(In reply to p5B2EA84B3 from comment #3)
Typo in find / -name "*linphone" showed no output.
it should read "*linphone*"

(In reply to p5B2EA84B3 from comment #3)
Sorry but I have to correct again:

Then I did 
# pkg install -y linphone 

and as user from xterm
> linphone |% tee linphone_first_run

this segfaulted again with the same output as yesterday but this first line:

2022-07-21 09:26:14:744 bctbx-error-bctbx_file_open: Error open No such file or directory

Comment 6 Felix Palmen 2022-07-21 08:16:00 UTC

(In reply to p5B2EA84B3 from comment #3)
Well, I didn't say anything about the messages because they look pretty much the same on my i386 machine where linphone doesn't crash, and your extra message is most likely caused by removing your user configuration. Without being able to reproduce the crash, I can't really analyze anything myself. But:

> Awaiting instructions for testing.
Indeed, you could try gathering more information. I would recommend building a package with debugging info. For that, add the following to your /usr/local/etc/poudriere.d/make.conf:

.if ${.CURDIR:M*/net/linphone}
WITH_DEBUG=yes
.endif

Then, run the resulting linphone binary in a debugger (e.g. lldb), and once it crashed, obtain a stacktrace of the crash (IIRC the command is 'bt' for that) and attach it here. If the crash is happening in linphone itself, this should shed some light on it.

Comment 7 Felix Palmen 2022-07-21 08:48:40 UTC

(In reply to Felix Palmen from comment #6)
Forgot to mention:

> run the resulting linphone binary in a debugger (e.g. lldb)
to do this, just execute
% lldb linphone
and then issue the 'r' command on the (lldb) prompt tu run it from the debugger.

When you're done (and obtained the stacktrace with 'bt'), the 'q' command will exit the debugger.

(In reply to Felix Palmen from comment #7)
Thank you for providing the debugging instructions. Here is the output:

> lldb linphone
(lldb) target create "linphone"
Current executable set to 'linphone' (i386).
(lldb) r
Process 1071 launched: '/usr/local/bin/linphone' (i386)

Did failing to resolve cause the crash?

Comment 9 Felix Palmen 2022-07-21 13:20:06 UTC

Unfortunately (yes, again), this stacktrace shows there is no linphone code involved in the crash.

I can't tell whether the problem is in Qt5Quick (x11-toolkits/qt5-declarative) or i915_dri.so (graphics/mesa-dri).

Could you please try running linphone like this:

% LIBGL_ALWAYS_SOFTWARE=true linphone

and if that avoids the crash, also

% LIBGL_DRI3_DISABLE=true linphone

and

% LIBGL_DRI2_DISABLE=true linphone

If any of these work, we know the problem isn't with linphone itself.

(In reply to Felix Palmen from comment #9)

Could you please try running linphone like this:

% LIBGL_ALWAYS_SOFTWARE=true linphone  ==> no crash

% LIBGL_DRI3_DISABLE=true linphone     ==> crash

% LIBGL_DRI2_DISABLE=true linphone     ==> no crash

Now Felix, thank you so much to sort things.
But what should I do fixing my problem? 
I have no clue what it is and where to start.

Comment 11 Felix Palmen 2022-07-21 15:36:01 UTC

(In reply to p5B2EA84B3 from comment #10)

> But what should I do fixing my problem?
TBH ... use a wrapper script to run linphone. It's not like it does any graphics that would require full hardware accel ;)

You could e.g. place something like this in PATH before /usr/local/bin:

#!/bin/sh
LIBGL_DRI2_DISABLE=true exec /usr/local/bin/linphone "$@"

---

As for further investigating this bug, probably attribute it to mesa-dri instead... (but I can't edit the title)

Comment 12 Felix Palmen 2022-07-21 15:53:25 UTC

BTW, if you want to still investigate more, you could try building both x11-toolkits/qt5-declarative and graphics/mesa-dri with WITH_DEBUG=yes (just like linphone before), to get a more meaningful stacktrace from the crash.

> How would you change the title of this PR?

I'm not even sure whether this would be the correct way to deal with it, currently asking for advice on IRC ;)

All I can say now is that I had a look at the function in mesa-dri code where your crash happens, and I'm more or less lost, it seems to be something about on-the-fly code generation for OpenGL... really no idea about that kind of stuff.

But I'd be very surprised if linphone code had anything to do with the crash. We verified it works with software rendering. My advice would still be, just use it that way for now, cause it doesn't seem to have complex UI things that really need hardware acceleration.

Hello Emmanuel,
I was told on IRC that you're maintaining DRM related things. Would you mind having a look at the stacktrace in comment #13 please? Thank you!

Comment 16 Emmanuel Vadot 2022-11-30 11:54:13 UTC

Latest mesa-dri doesn't ship i915_dri.so anymore.

> Latest mesa-dri doesn't ship i915_dri.so anymore.

True, but that noes not mean that the problem has "overcome by events".

Comment 18 Jan Beich 2022-11-30 18:27:00 UTC

comment 13 backtrace is not applicable to mesa-dri >= 22.0.0 per https://gitlab.freedesktop.org/mesa/mesa/-/commit/0cad451f007f

mesa-dri can probably re-enable i915 (via -Dgallium-drivers=i915) but it supports less GPUs per https://gitlab.freedesktop.org/mesa/mesa/-/commit/ceba7f695271

Comment 19 Emmanuel Vadot 2022-12-01 11:35:57 UTC

(In reply to p5B2EA84B3 from comment #17)

Of course it does, if you have the same (more or less) problem with latest mesa-dri (so with crocus/iris) please re-open.

Comment 20 Jan Beich 2022-12-01 14:50:10 UTC

i965 was replaced by crocus (Gen4-Gen7, Gen8LP) + iris (Gen8+) but i915c (Gen2-Gen3) was replaced by i915g (Gen3). i810 (Gen1) is gone upstream, didn't use i915kms.ko (i810 takes UMS path in xf86-video-intel) and was never enabled in mesa-dri.

The reporter didn't specify GPU but probably Gen3 as in https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Third_generation
