A prerequisite for building the NetFGPA source code is the
|
|
installation of
|
|
\begin{itemize}
|
|
\item \texttt{Xilinx\_SDNet\_2018.2\_1005\_9}
|
|
\item \texttt{Xilinx\_Vivado\_SDK\_2018\.2\_0614\_1954}

Both tools need to be installed to \texttt{/opt/Xilinx/},

|
as paths are hardcoded in various places.

\section{\label{chapterminus1:thesis}P4/NetFGPA Support Scripts}
|
|
To be able to compile P4 source code to the NetFPGA the collection of
|
|
scripts, Makefiles and sample code of P4-NetFGPA is required.
|
|
The repository \url{git@github.com:NetFPGA/P4-NetFPGA-live.git} needs
|
|
to be cloned to ``projects'' subdirectory as ``P4-NetPFGA''
|
|
of the user that wants to
|
|
compile the source code. Access to the repository is granted after
|
|
applying for access as described on
|
|
\url{https://github.com/NetFPGA/P4-NetFPGA-public/wiki}.
|
|
After that the variable \texttt{P4\_PROJECT\_NAME} in
|
|
\texttt{~/projects/P4-NetFPGA/tools/settings.sh} needs to be modified to
|
|
read \texttt{export P4\_PROJECT\_NAME=minip4}
|
|
instead of \texttt{export P4\_PROJECT\_NAME=switch\_calc}.
|
|
Sample code for installation:
|
|
\begin{tiny}\begin{verbatim}
|
|
mkdir -p ~/projects
|
|
git clone git@github.com:NetFPGA/P4-NetFPGA-live.git P4-NetFPGA
|
|
sed -i 's/\(P4_PROJECT_NAME=\).*/\1minip4/' ~/projects/P4-NetFPGA/tools/settings.sh
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
Version \textbf{v1.3.1-46-g97d3aaa} of the P4-NetPFGA repository was
|
|
used for creating the bitfiles of this project.
|
|
\begin{verbatim}
|
|
nico@nsg-System:~/projects/P4-NetFPGA$ git describe --always
|

\section{\label{appendix:netfpga:compile}P4/NetFGPA Compilation Process}
|
|
After having setup the compile host as described above, the script
|
|
\texttt{bin/do-all-steps.sh} that is included in the thesis' git
|
|
repository. With a NetFPGA card installed in the host, this script
|
|
will compile the P4 source code to PX and in a second step to HDL and
|
|
then upload the resulting bitstream to the NetFPGA. The compilation
|
|
process will log its output to the directory
|
|
\texttt{\~/master-thesis/netpfga/log/}.

|
\section{\label{appendix:netfpga:tests}P4/NetFGPA Tests}
|
|
In the following sections we describe functionality tests
|
|
of our code on the NetFPGA.
|
|
% ----------------------------------------------------------------------
|
|
\subsection{Test 1: IPv4 Egress}
|
|
In this test we test whether setting the output port based on the
|
|
IPv4 address.
|
|
First we get the integer values of the IPv4 addresses in python:
|
|
\begin{verbatim}
|
|
>>> int(ipaddress.IPv4Address(u"10.0.0.42"))
|
|
167772202
|
|
>>> int(ipaddress.IPv4Address(u"10.0.0.4"))
|
|
167772164
|
|
>>>
|
|
\end{verbatim}
|
|
After that we set the table table entries for the NetFPGA.
|
|
\begin{tiny}\begin{verbatim}
|
|
>> table_cam_add_entry realmain_v4_networks_0 realmain.set_egress_port 167772202 => 16 0 0 0 0
|
|
fields = [(u'hit', 1), (u'action_run', 3), (u'out_port', 8), (u'out_port', 8), (u'mac_addr', 48), (u'task', 16), (u'table_id', 16)]
|
|
action_name = TopPipe.realmain.set_egress_port
|
|
field_vals = [1, '16', '0', '0', '0', '0']
|
|

|
|
WROTE 0x44020250 = 0xa00002a
|
|
WROTE 0x44020280 = 0x0000
|
|
WROTE 0x44020284 = 0x0000
|
|
WROTE 0x44020288 = 0x10000000

|
|
action_name = TopPipe.realmain.set_egress_port
|
|
field_vals = [1, '16', '0', '0', '0', '0']
|
|
CAM_Init_ValidateContext() - done
|
|
WROTE 0x44020250 = 0xa000004
|
|
WROTE 0x44020280 = 0x0000
|
|
WROTE 0x44020284 = 0x0000
|
|
WROTE 0x44020288 = 0x10000000
|
|
WROTE 0x4402028c = 0x0001
|
|

|
|
READ 0x44020244 = 0x0001
|
|

|
|
success
|
|
>>
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
On the host we setup the ARP entries:
|
|
\begin{tiny}\begin{verbatim}
|
|
root@ESPRIMO-P956:~# ip neigh add 10.0.0.6 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0
|
|
root@ESPRIMO-P956:~# ip neigh add 10.0.0.4 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
And then we generate test packets and expect 4 packets to show up on
|
|
enp2s0f0.
|
|
The following \texttt{tcpdump} output shows the expected packets
|
|
arriving on enp2s0f0:
|
|
\begin{tiny}\begin{verbatim}
|
|
nico@ESPRIMO-P956:~$ sudo tcpdump -ni enp2s0f0
|
|

|
|

|
|
\end{verbatim}
|
|
\end{tiny}
|
|
% ok

|

|
|
\subsection{Test 2: IPv6 Egress}
|
|
This test shows how setting the egress port based on the IPv6 address
|
|
works with the NetPFGA. Similar to the previous test, we first the
|
|
the Integer values of the IPv6 addresses:
|
|
\begin{verbatim}
|
|
>>> int(ipaddress.IPv6Address(u"2001:db8:42::4"))
|
|
42540766411362381960998550477184434180L
|
|
>>> int(ipaddress.IPv6Address(u"2001:db8:42::6"))

42540766411362381960998550477184434242L

\end{verbatim}
|

After that we set the table entries:

nico@ESPRIMO-P956:~$ sudo ip -6 neigh add 2001:db8:42::6 lladdr f8:f2:1e:09:62:d0 dev enp2s0f1

\end{verbatim}
|

\end{tiny}
|
|
And generate the test packets:

\section{\label{appendix:bmv2}P4/BMV2 Environment and Tests}
|
|
All BMV2 based compilations were made with the following compiler:
|
|
\begin{verbatim}
|
|
p4@ubuntu:~$ p4c --version
|
|
p4c 0.5 (SHA: 5ae30ee)
|
|
\end{verbatim}
|
|
The installation is based on the vagrant files that were provided in
|
|
the ``Advanced Topics in
|
|
Communication Networks Fall 2018'' course of
|
|
ETHZ (\url{https://adv-net.ethz.ch/2018/}) and contains p4tools as
|
|
well as all utilities that came with the vagrant installation.
|
|
% ok
|
|
% ----------------------------------------------------------------------
|
|
For running the diff based checksum code, the following steps are
|
|
necessary: First compile the p4 code and then start the switch, both
|
|
with \texttt{p4run}.
|
|
\begin{verbatim}
|
|
cd ~/master-thesis/p4app
|
|
sudo p4run --config nat64-diff.json
|
|
\end{verbatim}
|
|
Then with starting the controller the required table entries will
|
|
\begin{verbatim}
|
|
cd ~/master-thesis/p4app
|
|
sudo python ./controller.py --mode range_router
|
|
\end{verbatim}

\chapter{\label{appendix:netpfgalogs}NetFPGA Logs}
|
|
The log files of the NetFPGA compilations are stored inside
|

the source code directory stored at \texttt{netpfga/logs}.

It follows a selection of excerpts of log files that might

be relevant for reproducing the work.

\section{\label{appendix:netpfgalogs:flasherror}NetFPGA Flash Errors}
|
|
Sometimes flashing bitfiles to the NetFPGA will fail. A random amount

of reboots (1 to 3) and a random amount of reflashing will fix this

|
problem.

Below can be found the log output from the flashing process.

A successful flashing process also emits a couple of errors, however

the message ``fpga configuration failed. DONE PIN is not HIGH'' and

its succeeding lines are missing, as seen below.

nico@ESPRIMO-P956:~$ sudo ip route add 10.0.1.0/24 via 10.0.0.77

And verify that networking works:

We also setup the IPv6 networking:
|

\begin{tiny}\begin{verbatim}
|

nico@ESPRIMO-P956:~$ ip addr show dev enp2s0f1

|
|
[15:15] nsg-System:~# ip link set eth2 up
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
And verify that IPv6 networking works:
|
|
\begin{verbatim}
|
|
nico@ESPRIMO-P956:~$ ping6 -c2 2001:db8:42::77
|

We enable IPv6 and IPv4 forwarding:
|

\begin{verbatim}

|

|
|
net.ipv4.ip_forward = 1
|
|
\end{verbatim}
|
|
And we test NAT64 with Tayga:
|
|
\begin{tiny}
|

\section{\label{benchmark:Jool}Jool}
|
|
We install Jool 4.0.1 from source from
|
|
\url{https://www.Jool.mx/en/download.html} as follows:
|
|
\begin{tiny}
|
|
\begin{verbatim}
|
|
nico@nsg-System:~$ wget https://github.com/NICMx/Jool/releases/download/v4.0.1/jool_4.0.1.tar.gz
|
|
nico@nsg-System:~$ tar xvfz jool_4.0.1.tar.gz
|
|
nico@nsg-System:~$ cd jool-4.0.1/
|
|
nico@nsg-System:~/jool-4.0.1$ sudo apt install linux-headers-$(uname -r)
|
|
nico@nsg-System:~/jool-4.0.1$ sudo apt install libnl-genl-3-dev
|
|
nico@nsg-System:~/jool-4.0.1$ sudo apt install iptables-dev
|
|
nico@nsg-System:~/jool-4.0.1$ sudo make install
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
We enable forwarding:
|
|
\begin{verbatim}
|
|
sysctl -w net.ipv4.conf.all.forwarding=1
|
|
sysctl -w net.ipv6.conf.all.forwarding=1
|
|
\end{verbatim}
|
|
We configure Jool to map the network prefixes and setup iptables to
|
|
redirect the traffic into the Jool instance:
|
|
\begin{tiny}
|
|
\begin{verbatim}
|
|
[16:53] nsg-System:~# modprobe jool_siit
|
|
[16:54] nsg-System:~# jool_siit instance add "example" --iptables
|
|
[16:54] nsg-System:~# jool_siit -i example eamt add 2001:db8:42::/120 10.0.1.0/24
|
|
[16:55] nsg-System:~# jool_siit -i example eamt add 2001:db8:23::/120 10.0.0.0/24
|
|
[16:57] nsg-System:~# ip6tables -t mangle -A PREROUTING -s 2001:db8:42::/120 -d 2001:db8:23::/120 -j JOOL_SIIT --instance example
|
|
[16:57] nsg-System:~# iptables -t mangle -A PREROUTING -s 10.0.0.0/24 -d 10.0.1.0/24 -j JOOL_SIIT --instance example
|
|
\end{verbatim}
|
|
\end{tiny}
|
|
Afterwards we test NAT64:
|
|
\begin{verbatim}
|
