This method allows safer deploys since\n+only the strictly forbidden system calls will be black-listed and the\n+possibility of breaking any workload is close to zero.\n+\n+The default option (-sandbox on) has a slightly looser security though and the\n+reason is that it shouldn't break any backwards compatibility with previous\n+deploys and command lines already running. But if the intent is to have a\n+better security from this version on, one should make use of the following\n+additional options properly:\n+\n+* obsolete=allow|deny: It allows Qemu to run safely on old system that still\n+ relies on old system calls.\n+\n+* elevateprivileges=allow|deny|children: It allows or denies Qemu process\n+ to elevate its privileges by blacklisting all set*uid|gid system calls. The\n+ 'children' option sets the PR_SET_NO_NEW_PRIVS to 1 which allows helpers\n+ (forks and execs) to run unprivileged.\n+\n+* spawn=allow|deny: It blacklists fork and execve system calls, avoiding QEMU to\n+ spawn new threads or processes.\n+\n+* resourcecontrol=allow|deny: It blacklists all process affinity and scheduler\n+ priority system calls to avoid that the process can increase its amount of\n+ allowed resource consumption.\n+\n+--\n+Eduardo Otubo <otubo@redhat.com>\n", "prefixes": [ "PATCHv4", "6/6" ] }
