Yes, this is detailed in 'man NetworkManager' if anyone wants to know: (a) a regular file (b) owned by root (c) not writable by group or other (d) not set-uid (e) and executable by the owner these permissions are for security reasons. Patches accepted to make the dispatcher warn about these issues in syslog, that might help make people aware of the problems. One issue is that since the dispatcher is a short-lived process, we dont' necessarily want to be warning every time an event happens, which can be quite often. Not sure how to deal with that though. I guess we could hack some bits into NetworkManager itself to warn about it, and leave that part out of the dispatcher, as long as the code to do the checks is shared. That might take the form of making a new static library in src/ that contains only a function that checks the status of the file like so: gboolean dispatcher_check_script (const char *path, GError **error); which would be used by both NM and the dispatcher. The dispatcher of course would ignore error, and simply not execute the script. NetworkManager on the other hand would run this for each file and print a warning on startup (eg, nm_log_warn ("Dispatcher script %s failed permissions checks: %s", script_path, error->message);).
