ci: cram: tr181-gre initial tests

Browse Source 
Add CRAM tests for tr181-gre, including an end-to-end tunnel test: the
remote peer lives in a network namespace behind a veth pair emulating
the WAN link, so the test is self-contained and is not tied to a
specific board. The end-to-end test drives the tunnel
through the data model (GRE.Tunnel + Interface + IP.Interface), verifies
the kernel route, reply behaviour with and without a peer return route,
the UseSequenceNumber/UseChecksum toggles and runs a short iperf3 session
through the tunnel.

End-to-end GRE tunnel test (IPv4-over-IPv4). The remote peer runs in a
network namespace on the DUT, connected through a veth pair that
emulates the WAN link, so the test is self-contained.
Create R alias:
$ alias R="${CRAM_REMOTE_COMMAND:-}"
$ R logger -t cram "Starting GRE E2E test"
Create the peer network namespace with a veth link emulating the WAN:
$ R "(ip netns add grepeer; \
> ip link add veth-gre type veth peer name veth-grep; \
> ip link set veth-grep netns grepeer; \
> ip addr add 192.168.78.1/24 dev veth-gre; \
> ip link set veth-gre up; \
> ip netns exec grepeer ip addr add 192.168.78.2/24 dev veth-grep; \
> ip netns exec grepeer ip link set veth-grep up; \
> ip netns exec grepeer ip link set lo up) > /dev/null 2>&1"
Configure the GRE peer endpoint inside the namespace:
$ R "(ip netns exec grepeer ip tunnel add gre1 mode gre remote 192.168.78.1 local 192.168.78.2; \
> ip netns exec grepeer ip addr add 10.0.1.1 dev gre1; \
> ip netns exec grepeer ip link set gre1 up) > /dev/null 2>&1"
Configure the CPE tunnel through the data model:
$ GRETIDX=$(R "ba-cli 'GRE.Tunnel.+{Alias=\"e2e\",Enable=1,RemoteEndpoints=\"192.168.78.2\",DeliveryHeaderProtocol=\"IPv4\"}'" 2>/dev/null | sed -ne 's/^GRE.Tunnel.\([0-9]\+\).$/\1/p')
$ R "ba-cli 'GRE.Tunnel.e2e.Interface.+{Alias=\"i1\",Enable=1}'" > /dev/null 2>&1
$ sleep 3
$ GREIFACE=$(R "ba-cli 'GRE.Tunnel.e2e.Interface.1.Name?'" | sed -ne 's/.*Name="\(.*\)"$/\1/p')
Assign an IPv4 address to the CPE GRE interface through the data model:
$ IPIDX=$(R "ba-cli 'IP.Interface.+{Alias=\"gre-e2e\",Enable=1,IPv4Enable=1,LowerLayers=\"Device.GRE.Tunnel.$GRETIDX.Interface.1.\",Router=\"Device.Routing.Router.1.\"}'" 2>/dev/null | sed -ne 's/^IP.Interface.\([0-9]\+\).$/\1/p')
$ R "ba-cli 'IP.Interface.$IPIDX.IPv4Address.+{Alias=\"gre-e2e\",AddressingType=\"Static\",IPAddress=\"10.0.1.2\",SubnetMask=\"255.255.255.0\",Enable=1}'" > /dev/null 2>&1
$ sleep 3
A route to 10.0.1.0/24 through the GRE interface is installed on the CPE:
$ R "ip route show 10.0.1.0/24 | grep -c \"dev $GREIFACE\""
1
Without a return route on the peer, echo replies do not come back:
$ R "ping -c 1 -W 2 10.0.1.1 > /dev/null 2>&1; echo \$?"
1
Add the return route on the peer and observe echo replies:
$ R "ip netns exec grepeer ip route add 10.0.1.2 dev gre1"
$ R "ping -c 3 -W 5 10.0.1.1 > /dev/null 2>&1; echo \$?"
0
Enable GRE sequence numbering on the CPE; traffic still passes:
$ R "ba-cli 'GRE.Tunnel.e2e.Interface.1.UseSequenceNumber=1'" > /dev/null 2>&1
$ sleep 2
$ R "ip -d link show $GREIFACE | grep -c oseq"
1
$ R "ping -c 3 -W 5 10.0.1.1 > /dev/null 2>&1; echo \$?"
0
Enable GRE output checksum on the CPE; the peer does not accept
checksummed packets yet, so echo replies stop:
$ R "ba-cli 'GRE.Tunnel.e2e.Interface.1.UseChecksum=1'" > /dev/null 2>&1
$ sleep 2
$ R "ip -d link show $GREIFACE | grep -c ocsum"
1
$ R "ping -c 1 -W 2 10.0.1.1 > /dev/null 2>&1; echo \$?"
1
Enable GRE input checksum on the peer; echo replies come back again:
$ R "ip netns exec grepeer ip link set gre1 type gre icsum"
$ R "ping -c 3 -W 5 10.0.1.1 > /dev/null 2>&1; echo \$?"
0
Run a short throughput test through the tunnel:
$ R "ip netns exec grepeer iperf3 -s -D > /dev/null 2>&1"
$ sleep 1
$ R "iperf3 -c 10.0.1.1 -t 2 > /dev/null 2>&1; echo \$?"
0
$ R "killall iperf3 > /dev/null 2>&1; true"
Cleanup:
$ R "ba-cli 'IP.Interface.$IPIDX.-'" > /dev/null 2>&1
$ R "ba-cli 'GRE.Tunnel.e2e-'" > /dev/null 2>&1
$ R "ip netns del grepeer > /dev/null 2>&1; true"
$ R logger -t cram "GRE E2E test finished"
