2018-05-21bgp_router_test: Retry assertions of RIB for stabilityIWASE Yusuke
To improve the stability of "bgp_router_test.py", this patch fixes to retry assertions of RIB on a Quagga router after shutting down a neighbor. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-05-15scenario_test: Wait for GoBGP starting upIWASE Yusuke
For the stability of some scenario tests, this patch fixes to wait for GoBGP starting up after restarting GoBGP daemon. Currently, there are cases that CLI command can be called without checking whether GoBGP daemon is surely started or not. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-05-15test/lib/gobgp: Rename graceful_restart() to stop_gobgp()IWASE Yusuke
GoBGPContainer.graceful_restart() does not "restart" GoBGP daemon, but just stops (kills) GoBGP daemon. Then this patch renames graceful_restart() to stop_gobgp() to avoid confusion. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

We had to serialize all the paths once because the paths could be modified later. Now they are immutable so we don't need. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

Now you can read Path objects in rib safely. Nobody modifies them. GetRib() API doesn't need to clone the objects. With full routes, this avoid allocating temporary huge memory. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2018-05-08gobgp/cmd: add router-mac option for BGP EVPN Type 2Paul Greenberg
The `router-mac` option in `gobgp` CLI allows sending Router's MAC Extended Community via BGP EVPN Type 2 and Type 5 advertisements. As explained in below RFC draft, this community is used to carry the MAC address of the VTEP where MAC-IP pair resides. More info: For example, GoBGP router (R1) peers with Cisco router (R2). R1 is used by an orchestraction platform, e.g. OpenStack, Docker Swarm, etc., to advertise container MAC-IP bindings. When R1 advertises the binding it also sets next hop for the route as the host where the MAC-IP binding (i.e. container) resides. When R2 receives the route, it will not install it unless Router's MAC Extended Community is present. R2 will use the MAC address in the community to create an entry in MAC address table of R2 pointint to NVE interface. ``` gobgp global rib -a evpn add macadv e9:72:d7:aa:1f:b4 \ 172.16.100.100 etag 0 label 34567 rd 10.1.1.1:100 \ rt 65001:100 encap vxlan nexthop 10.10.10.10 \ origin igp router-mac e9:72:d7:aa:1f:b4 gobgp global rib -a evpn add nexthop 10.10.10.10 origin igp \ prefix 172.16.100.100/32 esi 0 etag 0 rd 10.1.1.1:100 \ rt 65001:100 gw 10.10.10.10 label 34567 encap vxlan \ router-mac e9:72:d7:aa:1f:b4 ``` In the above example, a host with IP of `10.10.10.10` runs a container connected to an Open vSwitch instance. The container's IP address is `172.16.100.100` and MAC address `e9:72:d7:aa:1f:b4`. The Open vSwitch is VTEP with `tunnel_key=34567`, i.e. VNID `34567`. GoBGP (R1) and Cisco (R2) routers are in BGP AS 65001. R1's IP is `10.1.1.1`. R2 used RT of `65001:100` to import routes and place them into appropriate VRF. In this case the VRF is associated with L2VNI from VLAN 300. Upon the receipt of the above BGP EVPN Type 2 and Type 5 routes, R2 will create create a MAC address entry pointing to it's NVE interface with destination IP address of `10.10.10.10`. ``` Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link, (T) - True, (F) - False, C - ControlPlane MAC VLAN MAC Address Type age Secure NTFY Ports ---------+-----------------+--------+---------+------+----+------------------ * 300 e972.d7aa.1fb4 static - F F nve1(10.10.10.10) ``` The R2 will use the `router-mac e9:72:d7:aa:1f:b4` as the destination MAC address of the inner VXLAN packet. For example, an underlay host `20.20.20.20` ping the container. The inner VXLAN L2 destination address is `e9:72:d7:aa:1f:b4`. The inner VXLAN L2 source address is R2's MAC. The outer VXLAN L3 source address, i.e. `10.2.2.2` is R2' NVE address. ``` OUTER VXLAN L2: 10:20:08:d0:ff:23 > b2:0e:19:6a:8d:51 OUTER VXLAN L3: 10.2.2.2.45532 > 10.10.10.10.4789: VXLAN, flags [I] (0x08), vni 34567 INNER VXLAN L2: 4e:f4:ca:aa:f6:7b > e9:72:d7:aa:1f:b4 INNER VXLAN L3: 20.20.20.20 > 172.16.100.100: ICMP echo reply, id 66, seq 1267, length 64 ``` See also: https://tools.ietf.org/html/draft-sajassi-l2vpn-evpn-inter-subnet-forwarding-05#section-6.1 Signed-off-by: Paul Greenberg <greenpau@outlook.com>

2018-04-18fsm: Don't wait EoR if the peer is restartingSatoshi Fujimoto
RFC4724(Graceful Restart) says that if "Restart State" bit is set in the Open message, its peer must not wait for the EoR marker from the speaker before advertising routing information to the speaker. But currently, GoBGP waits EoR even if "Restart State" bit is set in graceful restart process. This commit fixes it to skipping syncing process for the restarting peers.

2018-04-09server: Avoid infinite UPDATE loop of RTM NLRIIWASE Yusuke
When GoBGP dropped adj-Rib-out per Peer, we fixed to send the same Route Target Membership (RTM) NLRI even if it is already sent. This can cause the infinite UPDATE loop when Route Reflector(RR) reflects RTM NLRI to its clients. For example, the following situation causes the infinite UPDATE loop. Topology: +----- RR -----+ | | Client1 Client2 When Client1 has VRF with RT 65000:1 and sends a RTM NLRI to RR, then RR reflects the NLRI to Client2. If a new VRF with the same RT 65000:1 on Client2 is created, Client2 will notify it to RR, then RR calculates the best, but RR will send the NLRI from Client2 to Client1 even if it is not the best. Client1 receives the NLRI again, calculates the best and re-sends the best. Then, RR reflects the received NLRI ... (infinite loop). This patch fixes to compare the candidate path to be sent with the old path and assume the given candidate path was already sent before if the candidate path and the old path is the same path. Then avoids the infinite UPDATE loop. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2018-04-03packet/bgp: Return nil for invalid redirect IP addressIWASE Yusuke
When initializing IPv4AddressSpecificExtended or IPv6AddressSpecificExtended structure, nil value will be returned when an invalid IP address is given. But the redirect action extended community types; - RedirectIPv4AddressSpecificExtended - RedirectIPv6AddressSpecificExtended which embed IP address specific extended community types, are not aware of nil value when initializing, so these redirect action extended community can be unexpectedly initialized with nil value. This patch fixes to check return value of the embedded structure and also return nil when failure of initializing it. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
