From 31527da5d673ed16255869b6d0f209285b8b0981 Mon Sep 17 00:00:00 2001 From: Yves-Alexis Perez Date: Tue, 2 Oct 2018 22:47:23 +0200 Subject: yama: clarify ptrace_scope=2 in Yama documentation Current phrasing is ambiguous since it's unclear if attaching to a children through PTRACE_TRACEME requires CAP_SYS_PTRACE. Rephrase the sentence to make that clear.
