Package: libc6
Version: 2.2.4-7
Severity: normal

If aio_read has been called for a socket and then closing the socket
is attempted with close, close succeeds (returns zero), but the connection
is not really closed until the remote end sends something completing the
pending aio_read. aio_cancel returns AIO_NOTCANCELED and does not do anything.

This is a problem in server applications: If the server is implemented in
such a way that it always listens for incoming data, it cannot close the
connection.

Ok, I am therefore closing the bug. Please feel free to reopen it if you
can reproduce it with a recent version of the glibc.
