totem crashed with SIGTRAP in __glXSendError() from MakeContextCurrent()

Bug #1758287 reported by dinamic on 2018-03-23

Affects Status Importance Assigned to Milestone
Fix Released
gstreamer-vaapi (Ubuntu)
mesa (Ubuntu)
totem (Ubuntu)



Backtrace goes through:

totem -> clutter-gst (frame update) -> cogl (pipeline free) -> gstreamer (buffer free) -> gstreamer-vaapi (destroy objects) -> Nvidia libglvd (CommonMakeCurrent / InternalMakeCurrentVendor) -> Mesa GLX (MakeContextCurrent) -> Xlib (XError)

Ubuntu bug doesn't say anything about what's the use-case / when this happens and whether it's reproducible (is it e.g. timing related), it seems just some random crash that Apport collects.

In the backtrace Mesa MakeContextCurrent() calls __glXSendError() to tell that it was given invalid/bad context. Corresponding Mesa code:
   if (gc) {
      /* Attempt to bind the context. We do this before mucking with
       * gc and __glXSetCurrentContext to properly handle our state in
       * case of an error.
       * If an error occurs, set the Null context since we've already
       * blown away our old context. The caller is responsible for
       * figuring out how to handle setting a valid context.
      if (gc->vtable->bind(gc, oldGC, draw, read) != Success) {
         __glXSendError(dpy, GLXBadContext, None, X_GLXMakeContextCurrent,
         return GL_FALSE;

I.e. bug is in what is given to Mesa, not what Mesa does.


To me it looks something that could happen when Totem is exiting, gst-vaapi is trying to use resources that have already been freed, and X catching that when Gstreamer gstvaapitexture_glx.c::destroy_objects() ask libglvnd to do CommonMakeCurrent().
