Summary:                    [patch] udhcp socket leaks
Description: 
>From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=336507 :

"While my ISP was playing up, udhcpc was getting 30 second leases from
the cable modem.  Somehow it managed to run out of file descriptors
and /proc/nn/fd showed a large number of sockets.  Using strace showed
it was creating a UDP socket, setting SO_REUSEADDR and then attempting
to bind it to a specific IP address.  The bind failed and the socket
was never closed.  Examining kernel_packet() we can see that if the
bind fails, the socket will remain open.  There are a number of
similar cases.  See the patch below. -- Neil Turton"
