             Bug ID: 75221
            Summary: CONFIG_PROC_SYSCTL is required for networking
            Product: Networking
            Version: 2.5
     Kernel Version: 3.14.2
           Hardware: All
                 OS: Linux
               Tree: Mainline
             Status: NEW
           Severity: normal
           Priority: P1
          Component: Other
           Assignee: shemminger@linux-foundation.org
           Reporter: stefan@konink.de
         Regression: No

I am in the proces of building an embedded kernel which I wanted to limit in
both functionality and memory. For this reason I disabled CONFIG_PROC_SYSCTL. I
have figured out the hard way that this functionality implements the successful
randomisation of source ports, it might be responsible for the initialisation
of net.ipv4.ip_local_port_range.

Effectively, booting a kernel with ip=dhcp works. Ping-pong (ICMP) to and from
an address works. DNS queries (UDP/53) don't because the source port remains 0,
a connection to a typical webserver also seems to result in a no reply
situation.
