Problem Summary PG4U.00092 This request claims the AF_UNIX SOCK_DGRAM test part fails because the server fails to close a conection after the AF_UNIX SOCK_STREAM test part.

Problem Text
This test may fail because bind() faild with EADDRINUSE error
on UNIX domain and streams type socket.

The first test of UNIX domain and a socket type did not close
the accepted fd, so the second test of UNIX domain and datagram type
fail to bind to the same address as stream type socket.

The change to the lib/capi_sock/unix.c module is as follows,

*** unix.c
--- unix.c.new
***************
*** 598,603 ****
--- 598,604 ----
sleep_server(fd);

close(fd);
+ close(s);
} else {
if (type == SOCK_DGRAM) {
tet_infoline("PREP: Server: notify client server is ready");

Review Response
We recommend this request be refused.

Using write test 14 as an example...

The AF_UNIX SOCK_STREAM part of the test forks a separate process
to act as the server for its part of the test. All the fds associated
with the server are a part of this separate process.

When the AF_UNIX SOCK_STREAM part of the test is finished it
sends a signal to the server process then waits for it to exit().
The server recieves this signal and exit()s via the function named
done(). We do not believe the portion of the code the submitter
suggests changing should be executed.

Since all the server fds are part of this server process we believe
they should all be closed and the socket should be dismantled before
the server process exits. So reusing the same socket address in the
next part of the test should be ok.
