2017-11-21packet/bgp: Use ESI str in EVPN Ethernet Segment RouteIWASE Yusuke
This patch fixes to use the string representation of ESI in the string representation of EVPN Ethernet Segment Route. Currently, displayed in the default representation of ESI structure. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-21packet/bgp: Avoid raw binary in EVPN ESI stringIWASE Yusuke
Currently, the value field of EVPN ESI might be corrupted when ESI type is ARBITRARY (not "single-homed") or unknown type because the value field will be formatted as the raw byte slice in this case. This patch fixes to convert the byte slice into the colon separated hex values which is corresponding to the format of the CLI input. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-21packet/bgp: Use decimal AS number in EVPN ESIIWASE Yusuke
Currently, the representation of AS number in EVPN ESI Type AS (Type 5) uses the colon separated 2 octet values format, but in other places, the AS4_PATH attribute for example, the single decimal format is used. This patch fixes to use the decimal AS number for the consistency with the AS_PATH/AS4_PATH attributes and also the CLI input format. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-21cli: EVPN Ethernet Auto-discovery Route advertisementIWASE Yusuke
This patch enables to add route for EVPN Ethernet Auto-discovery Route via "gobgp" command.

2017-11-21cli: Use network IP address for EVPN Prefix routeIWASE Yusuke
Currently, "gobgp" command use the host IP when adding a new EVPN Prefix route, but it should be the network IP address, otherwise the two routes to "192.168.0.1/24" and "192.168.0.2/24" will be determined as different routes. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-21cli: Missing keywords for EVPN Prefix RouteIWASE Yusuke
Currently, the keywords "rt" and "encap" for EVPN Prefix Route are unexpectedly ignored when parsing the inputs from "gobgp" command. Also, "label" is not described in the usage. This patch fixes to pass these keywords to be advertised and updates the usage format. Note: This patch makes "rt" as optional field in the usage because "rt" can be omitted when deleting. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-21cli: Support keyword args for EVPN macadv and multicastIWASE Yusuke
For improving readability of arguments, this patch supports keyword arguments "etag" and "label" when adding EVPN "macadv" and "multicast" routes. Also, this change makes it more easy to introduce new arguments. With this patch, both of the following formats are supported for the backward compatibility. New Format: <MACADV> : <mac address> <ip address> etag <etag> label <label> rd <rd> [rt <rt>...] [encap <encap type>] <MULTICAST> : <ip address> etag <etag> rd <rd> [rt <rt>...] [encap <encap type>] Old Format: <MACADV> : <mac address> <ip address> <etag> <label> rd <rd> [rt <rt>...] [encap <encap type>] <MULTICAST> : <ip address> <etag> rd <rd> [rt <rt>...] [encap <encap type>] Note: This patch makes "rt" as optional field in the usage because "rt" can be omitted when deleting.

2017-11-20packet/bgp: Rename snake case to camel caseIWASE Yusuke
This patch renames some variable names in snake case (e.g., "last_byte_value") to that in the camel case (e.g., "lastByte") because Go prefers the camel case for variable names. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-19packet/bgp: fix flowspec parser about cmd badly argsnnao45
2017-11-16api: Activate address family using Peer.AfiSafisIWASE Yusuke
Currently, to configure per AFI-SAFI settings when adding neighbor via gRPC API, it is require to specify the both Peer.Families and Peer.AfiSafis fields. If Peer.Families is omitted, settings in Peer.AfiSafis are ignored and the given address families are not activated. This patch enables to configure per AFI-SAFI settings and activate the address family with only Peer.AfiSafis (without Peer.Families). Note: For the backward compatibility, if only Peer.Families is specified, this patch creates per AFI-SAFI settings with the default settings. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-16api: Define constants for address familiesIWASE Yusuke
To call some gRPC APIs, it is required to specify the address family value which is combined value of AFI and SAFI values, so users of gRPC APIs need to calculate this value. This patch introduces the constants for the address families for the convenience. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-13api/grpc_server: Remove redundant loop for gRPC serverIWASE Yusuke
gRPC server should try to start serving only once because it send stopped signal to the waiter if server could not start. This patch removes redundant "for" loop to improve code inspection result. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-13api/grpc_server: Avoid name collision "server"IWASE Yusuke
To improve code inspection result, this patch renames "server" variables in NewServer() to "s" because "server" collides the imported package name "github.com/osrg/gobgp/server". Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-13api/grpc_server: Use make() for an empty slice declarationIWASE Yusuke
To improve code inspection result, this patch uses make() for an empty slice declaration instead of using empty literal initializer. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-13api/grpc_server: Avoid index error when invalid set-med valueIWASE Yusuke
Currently, with a invalid "set-med" value in a policy action, GoBGP will raise panic of "index out of range" because the unmatched regular expression is not handled. This patch fixes to handle errors during parsing the given med value. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-12cli: Support address families when adding neighborIWASE Yusuke
Currently, "gobgp" command does not support to configure address families capability when adding a new neighbor. This patch introduces a new option field to "gobgp neighbor add" command and enables to configure address families capability. Example: Specify address family names in comma separated format $ gobgp neighbor add 10.0.0.3 as 65003 family ipv4-unicast,l2vpn-evpn $ gobgp neighbor 10.0.0.3 ...(snip)... Neighbor capabilities: multiprotocol: ipv4-unicast: advertised l2vpn-evpn: advertised route-refresh: advertised 4-octet-as: advertised ...(snip)...

2017-11-08config: Properly set config of PeerGroup memberSatoshi Fujimoto
Currently, the config of PeerGroup members are not set properly. For example, if LocalAs of the neighbor is not set in the config file, LocalAs will be set to Global.As as a default value. After this, however, if the neighbor is a member of a peer group, LocalAs will be unexpectedly overwritten by the peer group config. This commit fixes this by setting default values after applying the peer group config. Adding to this, this commit avoids unnecessary applying the peer group config.

2017-11-07test/lib: Enhancement on Get Rib library on QuaggaSatoshi Fujimoto
For Quagga containers, currently, when we use get_global_rib() without specifying prefix, we cannot get AS_PATH and other attributes. And when we use get_global_rib() with prefix, we can get only one path even if there is multiple paths for a destination. This commit fixes these problems by refining test/lib/quagga.py.

2017-11-07travis: Update .travis.ymlIWASE Yusuke
For scenario_test, Python build environment is more suitable rather than Go build environment, because scenario_test is written in Python and the building source codes will be done on Docker containers. This patch fixes scenario_test to use Python build environment and reduces "sudo" executions in order to use interpreter of virtualenv. Note: On Travis-Ci, the Python interpreter of sudoer is older version, and when install packages with "sudo pip", InsecurePlatformWarning will be displayed. So it is better to use the newer interpreter of virtualenv. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-07server: Avoid local paths left on iBGP peersIWASE Yusuke
Currently, with iBGP peering, the CLI injected path will not be withdrawn when the deletion if any other path exists on RIB, then the CLI injected path will be left on iBGP peers even if the route is deleted on the originator router. This problem can cause routing loops in some case. This patch fixes to withdraw the old best path when it was the CLI (or gRPC) injected path. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-07*: Fix problems pointed by 'go vet'Satoshi Fujimoto
In the near feature (likely in Go1.10), 'go test' will never work if 'go vet' fails. (See: https://github.com/golang/go/issues/18084) This commit is for dealing with such a situation (and also for improving the quality of our code). Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>
2017-11-06packet/bgp: Avoid Varied Flag Representations in Flowspec FilterSatoshi Fujimoto
Currently, the parsing results of flags in flowsspec filter will be varied every time they are parsed. For example, the tcp-flag '=UFP' may be represented to '=UPF' or '=PUF' and so on. This is due to the use of interation to map. Iterations over maps does not happen in a consistent order. This fixes it by iterating sorted slices instead of maps.

2017-11-03packet/bgp: Remove non route key fields from stringIWASE Yusuke
RFC7432 and draft-ietf-bess-evpn-prefix-advertisement says some fields in EVPN NLRIs (e.g., MPLS Label(s)) should no be treated as the route key, but currently, GoBGP's string representations of EVPN NLRIs include all fields. So the paths should be treated as the same (e.g., only different in MPLS Label and other field is the same) can be treated as the different. This patch removes non route key fields from NLRI string representation and fixes this problem. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
