The typo in function Less() was causing logical error during comparison and the comparison would always return whether AS number was less or not regardless of Maxlen. fixes #1633
2018-04-03packet/bgp: Getter functions for AS segmentIWASE Yusuke
This patch adds getter functions for the segment type and AS list of each segment without using type assertion. 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.

When using IDE (e.g. VSCode), we can easily check the results of markdownlint and it should not be a heavy burden to write docs. This patch introduces an unit test to invoke markdownlint on Travis-CI. See https://github.com/DavidAnson/markdownlint/blob/master/doc/Rules.md, for configuration details of ".markdownlint.json".

2018-03-28cmd/common: Specify number of expected argumentsSatoshi Fujimoto
In CLI operation, currently, unexpected argument names (such as 'aspath' for 'gobgp neighbor add') may pass the validations and return no errors.

2018-03-27server/server: Set rsRib to RS client in adding dynamic neighborSatoshi Fujimoto

2018-02-23zclient: Avoid directly access to RIBIWASE Yusuke
In order to avoid races, zclient should not access to RIB without calling APIs of BgpServer. But currently zclient directly accesses to the global RIB when handling NEXTHO_UPDATE messages. This patch fixes this problem by calling BgpServer.GetRib(). Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-02-22packet/bgp: Return specified type value for UnknownExtendedIWASE Yusuke
Currently, "UnknownExtended.GetTypes()" returns always the constant values even if "Type" value is given. This patch fixes to return the given type value and use the first "Value" byte as the sub type. Also, introduces "NewUnknownExtended()" function for the convenience.

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>

The other interface types in "packet/bgp" package have "Interface" suffix. This patch fixes to follow this naming convention. Golang's naming convention recommends to use "er" suffix though. Also, this patch moves the AIGP TLVs definitions to the near of the PathAttributeAigp structure and defines NewAigpTLVDefault function. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2018-02-16table/path: Originator ID for locally generated pathsIWASE Yusuke

2018-02-16cli: Support to advertise PMSI Tunnel AttributeIWASE Yusuke
This patch enables "gobgp" command to advertise the PMSI Tunnel Attribute which is appended to the EVPN Inclusive Multicast Ethernet Tag routes for example.

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>
2018-01-27test/lib/gobgp: Adding routes without reloadingIWASE Yusuke
With the current implementation, when adding routes on GoBGPContainer, we re-configure and reload daemon, then add routes using CLI command. Differ from QuaggaBGPContainer, when deletion of routes, reloading is not required, but if reloading daemon frequently, we need to wait for the daemon restarting, it causes testing time longer and unstable. This patch enables to add routes without reloading daemon. Note: According to this change, adding routes should be called after starting daemons. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
