History
Maxim Konovalov 70df31f4de o There are two methods to get a process credentials over the unix 
sockets:

1) A sender sends SCM_CREDS message to a reciever, struct cmsgcred;
2) A reciever sets LOCAL_CREDS socket option and gets sender
credentials in control message, struct sockcred.

Both methods use the same control message type SCM_CREDS with the
same control message level SOL_SOCKET, so they are indistinguishable
for the receiver.  A difference in struct cmsgcred and struct sockcred
layouts may lead to unwanted effects.

Now for sockets with LOCAL_CREDS option remove all previous linked
SCM_CREDS control messages and then add a control message with
struct sockcred so the process specifically asked for the peer
credentials by LOCAL_CREDS option always gets struct sockcred.
