Are you objecting to specifically making this a system call, or
implementing it in general? I.e., is a socket option acceptable?
Basically, this thread is about trying to find a mechanism that can be
used to meet these two conditions on unix domain sockets:
1. Server can obtain the credentials of the connect() caller.
2. The above can be done without depending on the connect() caller
to send any data through the socket.
Condition 1 is easy to meet; SCM_CREDS already exists. On the other
hand, nobody has found an existing way to meet condition 2. If you
can change this (i.e., describe a way to do this for the list), great.
Otherwise, I have a patch[1] that implements this as a socket option,
and William Baxter has a patch to implement it as a system call.
