DYama.rst25 exist and remain possible if ptrace is allowed to operate as before.
26 Since ptrace is not commonly used by non-developers and non-admins, system
30 specifically disallow such ptrace attachment (e.g. ssh-agent), but many
31 do not. A more general solution is to only allow ptrace directly from a
43 to ptrace each other. If a process wishes to entirely disable these ptrace
50 0 - classic ptrace permissions:
57 1 - restricted ptrace:
67 only processes with ``CAP_SYS_PTRACE`` may use ptrace, either with
71 no processes may use ptrace with ``PTRACE_ATTACH`` nor via
