[Bug 1713313] Re: Unable to launch pkexec'ed applications on Wayland session

 

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.
