2017-06-20peer: Set NeighborAddress before initializing dynamic peersSatoshi Fujimoto
If State.NeighborAddress is not set, setting default configs for the dynamic peers will fail. This patch set State.NeighborAddress before setting default configs. And this patch avoids overwriting State.NeighborAddress if it is set. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>

2017-06-16config: Use State to get NeighborAddress instead of ConfigSatoshi Fujimoto
By introducing dynamic neighbor feature, GoBGP can have dynamic neighbors, and corresponding Config.NeighboAddress can be empty. This patch sets State.NeighborAddress for all neighbors, and gets the neighbor's address from them. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>
2017-06-09bmp: Support number of withdraw updates and prefixesIWASE Yusuke
This patch enables to send BMP statistics reports for the following types; - Stat Type = 11: (32-bit Counter) Number of updates subjected to treat-as-withdraw treatment. - Stat Type = 12: (32-bit Counter) Number of prefixes subjected to treat-as-withdraw treatment. Note: Currently, this implementation considers only updates or prefixes received from neighbors, but not enough to follow the handling process described in RFC7606.

2017-06-06server_test: Test for Graceful Restart timer expiredIWASE Yusuke
This test case checks whether BGP session is freed or not when Graceful Restart timer expired. If BGP session is not freed as expectedly, this test case will exit with state 1 after waiting 120 seconds and will output the following. FATA[0147] failed to free the fsm.h.t for 127.0.0.1 BGP_FSM_OPENSENT BGP_FSM_IDLE Topic=Peer Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2017-06-06server_test: stop listeningIWASE Yusuke
Listening on well-known port require the root privileges. This patch stop listening to avoid that because this test doesn't need to accept a peer. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-06-06server_test: Confirm BgpServer started and stoppedIWASE Yusuke
For each test case, this patch enables to confirm BgpServer is started successfully and stopped at the of each test case, otherwise the context of some test cases might affect other test cases. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-06-05*: Support Peer-Group ConfigurationSatoshi Fujimoto
This patch enables to create peer-groups, also supports dynamic configuration to peer-groups. Manually set fields in neighbor configs have priority over its peer-group's config, except some fields, like "peer-as", or "minimum-advertisement-interval" and so on.

2017-06-03server: Implement event for BGP message watcherIWASE Yusuke
This patch enables to watch events for monitoring received BGP messages before the state comparison. Note: Currently, this event nortifies UPDATE message only, because the other messages will be handled in FSMHandler and not received at BgpServer, so BgpServer cannot send event for these messages.

2017-05-23bmp: Implement Information TLV on Initiation messageIWASE Yusuke
Currently, the TLV fields are implemented as BMPTLV on the Initiation messages, but not enough decoded and required to be constructed in binary format. This patch introduces BMPInfoTLV and makes easy to handle the TLV fields. Note: This patch obsoletes BMPTLV structure. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-05-22bmp: Stats reports for Adj-RIBs-In and Loc-RIB routesIWASE Yusuke
This patch enable to send BMP statistics reports for the following types; - Stat Type = 7: Number of routes in Adj-RIBs-In = Regarding number of "accepted" routes in AdjTable state - Stat Type = 8: Number of routes in Loc-RIB = Regarding number of "advertised" and "filtered" routes in AdjTable state which means the all routes selected by the local BGP speaker's Decision Process.

This patch extend the "AdjTable" container to store the number of the "filtered" routes which should not be advertised to the given neighbor. This routes mean the filterd routes because of RTC, VRFs, policy and other constraints. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-05-22bmp: Obsolete "both" option for route-monitoring-policyIWASE Yusuke
Because of the introduction of "local-rib" and "all" options for route-monitoring-policy, this patch obsoletes "both" option. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-05-22bmp: Fix peer header info in Loc-RIB route messageIWASE Yusuke
"draft-evens-grow-bmp-local-rib" says the peer header for Loc-RIB monitoring should include the following values; - Peer Address: Zero-filled as remote peer address is not applicable. - Peer AS: Set to the BGP instance global or default ASN value. - Peer BGP ID: Set to the BGP instance global or RD (e.g. VRF) specific router-id. This patch fixes the peer header construction to follow this specification. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-05-22bmp: Enable to specify all route monitoring policiesIWASE Yusuke

2017-05-17server/fsm_test.go: fix race condition during testsChris Stockton
Add sync.Mutex to guard access to MockConnection to prevent tests ran with -race from failing. In addition change the calls to the fmt package to use t.Log show they only show with the -v flag to prevent unwanted noise between test runs. It has the added benefit of providing a file and line number as well.
2017-05-14server: avoid sending unwanted withdrawals to iBGP peersWataru Ishida

2017-05-10*: support replace-peer-as (aka as-override)Wataru Ishida
we use the term replace-peer-as instead of as-override since openconfig is using it. cli ``` $ gobgp n add <neighbor-addr> as <asn> replace-peer-as ``` config ``` neighbor: config: peer-as: <asn> neighbor-address: <neighbor-addr> as-path-options: config: replace-peer-as: true ``` Signed-off-by: Wataru Ishida <ishida.wataru@lab.ntt.co.jp>
2017-05-09server: ignore routes when local AS is in AS_PATHISHIDA Wataru
RFC4271 9.1.2 Phase 2: Route Selection If the AS_PATH attribute of a BGP route contains an AS loop, the BGP route should be excluded from the Phase 2 decision function. AS loop detection is done by scanning the full AS path (as specified in the AS_PATH attribute), and checking that the autonomous system number of the local system does not appear in the AS path. Operations of a BGP speaker that is configured to accept routes with its own autonomous system number in the AS path are outside the scope of this document. Also this commit adds support for allow-own-as option to relax this. Signed-off-by: ISHIDA Wataru <ishida.wataru@lab.ntt.co.jp>

2017-04-18policy: send a withdrawal if export policy blocks an existing routeISHIDA Wataru
This patch fixes a bug of export policy and implicit withdrawal. When a path is filtered by export policy, we need to check whether the old path (implicit withdrawn path) was sent before the new path. If it has been sent, we need to send a withdrawal message.

2017-04-17packet/bmp: Obsolete policy argument for BMPPeerHeaderIWASE Yusuke
According to "draft-evens-grow-bmp-local-rib", the L flag in the Peer Flags is NOT used for the locally sourced routes and the F flag is defined into the same bit. This patch removes "policy" argument and add "flags" argument for BMPPeerHeader and NewBMPPeerHeader in order to distinguish which flag is set (the L flag or the F flag). Then introduce IsPostPolicy() func to show if the L flag is set or not. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2017-03-27server/zclient: Retry Zebra message version negotiationIWASE Yusuke
Currently, the Zebra message version used by ZClient is configurable (default 2), but if the given version is miss-matched with that of Zebra daemon, ZCient will fail to connect. This patch fixes ZClient to retry the version negotiation. For example, if failed with the version 2, retry with the version 3. Note: In order to receive the first message from Zebra daemon when instantiating ZClient, this patch fixes ZClient to send HELLO and ROUTER_ID_ADD messages automatically.
