Subject: [PATCH] su: fix lastlog and btmp logging
The su(1) logging code mix ups "old" and "new" passwd structs. The
result is things like
Sep 9 11:50:45 x2 su: (to kzak) kzak on none
in /var/log/messages. The right log entry is
Sep 9 11:50:45 x2 su: (to root) kzak on pts/3
The bug has been introduced by commit c74a7af17c7a176c358dfaa8e1814786c89ebc14.
