The clone3 flag resets all signal handlers of the child not set to SIG_IGN to SIG_DFL. It allows to skip most of the sigaction calls to setup child signal handling, where previously a posix_spawn had to issue 2 times NSIG sigaction calls (one to obtain the current disposition and another to set either SIG_DFL or SIG_IGN). With POSIX_SPAWN_SETSIGDEF the child will setup the signal for the case where the disposition is SIG_IGN. The code must handle the fallback where clone3 is not available. This is done by splitting __clone_internal_fallback from __clone_internal. Checked on x86_64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
