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>

2018-04-03packet/bgp: Avoid data races when serializingIWASE Yusuke
Because "Serialize()" functions of NLRIs or PathAttributes can be called from some different goroutines, updating fields of a structure can cause data races. This patch moves the normalization for each field (mostly length and flags calculation) into "NewXxx()" or "DecodeFromBytes()" and avoids the data races.

2018-02-23zclient: Avoid directly access to RIBIWASE Yusuke

2018-02-22packet/bgp: Return specified type value for UnknownExtendedIWASE Yusuke

2018-02-22packet/bgp: Flatten structure of OpaqueExtendedIWASE Yusuke
Currently, to instantiate sub types of the Opaque Extended Community, it is required to instantiate "OpaqueExtended" and its value type (e.g., "ValidationExtended" or "EncapExtended") and also specify its sub type. This can cause the confusion of the outer and inner (value) structures and the unmatch of the value structure and its sub type. This patch makes the "OpaqueExtended" into more flat structure and introduces "NewXxxExtended()" function to improve usability. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2018-02-13packet/bgp: Missing String()/MarshalJSON() of PathAttribute subsIWASE Yusuke
First this patch removes String() and MarshalJSON() functions of PathAttribute struct. This helps to find the struct types which embed PathAttribute struct without having own String() and MarshalJSON() functions. If those functions of PathAttribute struct are unexpectedly called, those functions are not enough to display its contents. Then this patch implements missing String() and MarshalJSON() functions for some struct types which embed PathAttribute struct. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-02-13packet/bgp: Remove raw binary field on PathAttributeIWASE Yusuke

2018-02-10test/lib/exabgp: Use exabgpcli to add/del routesIWASE Yusuke
Currently, to advertise or withdraw routes with ExaBGPContainer, we need to configure static routes via config file and restart ExaBGP daemon. In other words, we can NOT send withdrawing advertisement with ExaBGPContainer. Also, restating ExaBGP daemon frequently can make scenario test unstable, and it should be avoided. On the other hand, with ExaBGP version 4.0.5 or later(*), we can advertise or withdraw routes using "exabgpcli" without restating ExaBGP daemon (or writing application which calls ExaBGP's APIs). This patch fixes to use "exabgpcli" and reduces the number of restating ExaBGP daemon. Note: According to this change, adding routes into ExaBGP should be called after adding neighbor. (*): "exabgpcli" is introduced at version 4.0.2, but has some bugs related to Python 3 compatibility and FlowSpec rules combinations, then we need to use version 4.0.5 or later.

2018-01-27scenario_test: Enable to try assertion several timesIWASE Yusuke
Some times, on Travis-CI, some test cases fail unexpectedly in checking paths in RIBs due to advertisements are not yet received from other routers. Currently, in order to avoid this unexpected result, "time.sleep" is inserted after adding new routes, but it is not enough. This patch introduces a new function to enable to do assertion several times and avoid failure with the first assertion. Note: This patch does not introduces this change into all test cases, do only into some test cases which fail relatively frequently. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
