Created attachment 121068 [details]
trace of plasmashell segmentation fault in Plasma 5.15.5 on Wayland with Qt 5.12.4

I saw segmentation faults of plasmashell in wl_proxy_marshal_constructor at wayland-client.c:819 when starting Plasma 5.15.5 on Wayland in Fedora 30. These crashes occurred on startup of one session, and three times in another session. These crashes started right after I updated from Qt 5.12.1 to 5.12.4 from koji along with the dependent Plasma and KF5 rebuilds. drkonqi wouldn't allow me to submit the attached trace which had the following segmentation fault and crashing thread.

Application: Plasma (plasmashell), signal: Segmentation fault

I think the segmentation fault might've been due to a null pointer dereference since proxy=0x0 in the wl_proxy_marshal_constructor call, and proxy was dereferenced at wayland-client.c:820 in proxy->object.interface->methods[opcode].signature

The wl_proxy_marshal_constructor function was as follows

812     WL_EXPORT struct wl_proxy *
813     wl_proxy_marshal_constructor(struct wl_proxy *proxy, uint32_t opcode,
814                                  const struct wl_interface *interface, ...)
815     {
816             union wl_argument args[WL_CLOSURE_MAX_ARGS];
817             va_list ap;
818
819             va_start(ap, interface);
820             wl_argument_from_va_list(proxy->object.interface->methods[opcode].signature,
821                                      args, WL_CLOSURE_MAX_ARGS, ap);
822             va_end(ap);
823
824             return wl_proxy_marshal_array_constructor(proxy, opcode,
825                                                       args, interface);
826     }

Functions from qt5-qtwayland at #8-10 and qt5-qtdeclarative lower in the crashing thread might be involved. I've seen a similar segmentation fault in plasmashell with qt 5.12.4 with a different trace which I might make another report for.

Is similar code needed also for QtWaylandClient::QWaylandAbstractDecoration::contentImage() in addition to QtWaylandClient::QWaylandWindow::handleUpdate()?

See https://bugs.kde.org/buglist.cgi?bug_severity=crash&resolution=---&chfieldfrom=90d&longdesc=QtWaylandClient::QWaylandAbstractDecoration::contentImage&longdesc_type=allwordssubstr
Comment 10 David Edmundson 2019-07-07 13:55:18 UTC
>QtWaylandClient::QWaylandAbstractDecoration::contentImage() 

I don't think so, it's in the main thread so a different issue.

Though the fact that we're in deco drawing code is already a sign of something weird.

Possibly fixed by https://codereview.qt-project.org/c/qt/qtwayland/+/262587 ?
Comment 11 Matt Fagnani 2019-07-07 16:05:55 UTC
I requested that David's patch in comment 5 be backported to Qt 5.12.4 in Fedora 30 at https://bugzilla.redhat.com/show_bug.cgi?id=1723017

Jan Grulich added four patches to qt5-qtwayland-5.12.4-2 which didn't appear to include that patch 
https://src.fedoraproject.org/rpms/qt5-qtwayland/c/287f373520b3c3864a822304fac2b2c2f358ac8a?branch=f30

I've seen the segmentation faults in wl_proxy_marshal_constructor about nine times with qt5-qtwayland-5.12.4-2. Sometimes the desktop colors became grayscale before the crash. plasmashell usually restarted, but I had to start plasmashell from konsole at least three times. I tried to apply David's patch to the Fedora qt5-qtwayland repo I cloned, but I got errors with applying part of the patch as follows.

The part of the patch with the error in src/client/qwaylandwindow.cpp.rej was

Could that patch be backported to Qt 5.12? Thanks.
