From: Nadav Amit <namit@xxxxxxxxxx> Non-cooperative mode is useful but only for forked processes. Userfaultfd can be useful to monitor, debug and manage memory of remote processes. To support this mode, add a new flag, UFFD_REMOTE_PID, and an optional second argument to the userfaultfd syscall. When the flag is set, the second argument is assumed to be the PID of the process that is to be monitored. Otherwise the flag is ignored. The syscall enforces that the caller has CAP_SYS_PTRACE to prevent misuse of this feature.
What supposed to happen if the target process intents to use uffd itself? -- Thanks, David / dhildenb
