Comment 25 for bug 1713313

The Python/GTK3 GUI GameConqueror uses libscanmem for memory scanning with /proc/$pid/mem or ptrace(). Root privileges are required because of the Yama security module and its ptrace_scope set to 1.

To bypass that, scanmem/GC would have to run the target application. That architecture change cannot be done as the usage would be too complex.

We cannot go back to parsing scanmem output due to performance reasons. The hot scanning path is called several million times. The results list is autoupdated and the hex memory editor receives a bigger amount of data from libscanmem. Running a memory scanning daemon is a security risk as any program might access it.

We expect that this is fixed in Wayland.
