           Summary: accept() doesn't wake with error when socket descriptor
                    closed
           Product: Networking
           Version: 2.5
     KernelVersion: 2.6.18

        AssignedTo: shemminger at linux-foundation.org

Most recent kernel where this bug did not occur: no idea
Distribution: no idea - remote server
Hardware Environment: i686
Software Environment: no idea - probably pure console server

Problem Description:
In multithreaded process, one thread launches accept() on a valid-so-far
listening socket file descriptor sockfd and waits on it. After this second
thread launches close( sockfd ). First thread further waits on accept() even
though the descriptor is now invalid. accept() should wake up and return with
-1 and errno EBADF.

Steps to reproduce:
described above
