What is yama? I don't recall seeing it as a kernel configuration option. and I just just tumbleweed and don't see a package named yama anything.
Yama is a relatively small security module (LSM). It is enabled by CONFIG_SECURITY_YAMA and adds restrictions to how programs can use the ptrace syscall. These restrictions can be managed at runtime with a sysctl knob: https://www.kernel.org/doc/Documentation/security/Yama.txt The highest setting (ptrace_scope=3) will be interesting mainly for servers and other locked down systems. In the lowest setting (ptrace_scope=1), usability issues are extremely rare. This is Ubuntu's default since 2010.
Sorry for being under-informed.
I left out essential information, sorry for this.
