In 2.6.23, there seems to be a minor bug in sys_socketpair. When the
calls to sock_alloc_fd fail, it aborts the routine, but it returns the
variable err, which is not set in this case.
The result is a silent failure if you have too many files open and call
socketpair.
Here is a simple UNTESTED patch (not even compiled) which should resolve the
issue.
Regards,
Rich
