SYNOPSIS

#include <sys/driver_hooks.h>
set_driver_hook( H_LOAD_UIDS, value)

DESCRIPTION

Arguments:
  • value (closure) – mixed <closure> (string objectname)

Mandatory hooks to determine the uid and euid of loaded or cloned objects. Hook settings can be any closure.

When an object is newly loaded, the H_LOAD_UIDS(H) hook is called with the object name as argument. The new object already exists, but has 0 uids.

For the result, the following possibilities exist (<num> is a non-zero number, <no-string> is anything but a string):

"<uid>"                    -> uid = "<uid>", euid = "<uid>"
({ "<uid>", "<euid>" })    -> uid = "<uid>", euid = "<euid>"
({ "<uid>", <no-string> }) -> uid = "<uid>", euid = 0

If strict-euids is not active, the following results are possible, too:

<num>                      -> uid = 0, euid = 0
({ <num>, "<euid>" })      -> uid = 0, euid = "<euid>"
({ <num>, <no-string> })   -> uid = 0, euid = 0
