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.
