Bug#526734: libc: poll not working on ipv4 socket
Package: libc6
Version: 2.9-9
Severity: normal
File: libc
The following code:
if (poll(monitor,1,READ_TIMEOUT)==0) {
r=0;
} else {
r = read(fd,buf-buffer,buf-size);
}
Works as expected (giving up the read after the timeout if there is no data) if
fd is an ipv6 socket, but does a blocking read if fd is an ipv4 socked.
If required, i can provide the full source code.

Yes, please provide a simple testcase showing this behaviour. Without
context, it is difficult to see if the code is correct or not.
