* According to POSIX 1003.1:
|
|
* "The saved set-user-ID capability allows a program to regain the
|
|
* effective user ID established at the last exec call."
|
|
* However, the setuid/setgid function as specified by POSIX 1003.1 does
|
|
* not allow changing the effective ID from the super-user without also
|
|
* changed the saved ID, so it is impossible to get super-user privileges
|
|
* back later. Instead we provide this feature independent of the current
|
|
* effective ID through the seteuid/setegid function. In addition, we do
|
|
* not use the saved ID as specified by POSIX 1003.1 in setuid/setgid,
|
|
* because this would make it impossible for a set-user-ID executable
|
|
* owned by a user other than the super-user to permanently revoke its
|
|
* extra privileges.
