Summary

0000751: [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"
