gobgp's Issues

IPv6 support for unicast and flow spec SAFI

Hello, folks!

Will be fine if you could add support for IPv6. So I could work as tester here and build C++ integration for IPv6 too :)

C/C++ integration code

Hello, folks!

I'm developer of https://github.com/FastVPSEestiOu/fastnetmon and I widely use BGP and Flow Spec.

My Customers asked me about GoBGP integration https://github.com/FastVPSEestiOu/fastnetmon/issues/389 And I really like your project!

So I have found this nice page https://github.com/osrg/gobgp/blob/master/docs/sources/grpc-client.md and looking for some way for C++/C integration.

Thus I could add GoBGP syntax to my BGP Flow Spec library (it's generates flow spec from C structures): https://github.com/FastVPSEestiOu/fastnetmon/blob/master/src/bgp_flow_spec.h and feed it with CLI.

But I looking for some way for more deeper integration :) Could you help me?

gobgp segmentation fault when working with community

Hello, Network Gurus!

I have broken your tool when plying with communities :( I'm so sorry about it.

I have created announce:

gobgp global rib add 10.33.1.0/24 -a ipv4

Then I have created blackhole community:

gobgp policy community add blackhole 65000:666

And enabled it for all exported prefixes:

gobgp neighbor 213.133.111.200 policy add export blackhole accept

After this operations source session goes away:

gobgpd

Nil value in not yet initizalied peer name

Hello!

I have some peer in configuration and when I start GoBGP and before peer init I'm getting NIL instead remote router ID:

gobgp nei xxxx
BGP neighbor is xxxx, remote AS xxxx
  BGP version 4, remote router ID <nil>
  BGP state = BGP_FSM_ACTIVE, up for 00:00:00
  BGP OutQ = 0, Flops = 0
  Hold time is 0, keepalive interval is 0 seconds
  Configured hold time is 90, keepalive interval is 0 seconds
  Neighbor capabilities:

When peer initialized correctly I get correct IP address instead NIL ;) So issue exists only between GoBGP startup and peer initialization.

How to enable multiple SAFI's?

Hello!

Sorry for bothering you but I haven't any examples How I could specify multiple SAFI's.

I'm using this configuration:

[Global]
  [Global.GlobalConfig]
    As = 65001
    RouterId = "178.62.227.110"

[Neighbors]
  [[Neighbors.NeighborList]]
    [Neighbors.NeighborList.NeighborConfig]
      NeighborAddress = "213.133.111.200"
      PeerAs = 65001
    [Neighbors.NeighborList.AfiSafis]
      [[Neighbors.NeighborList.AfiSafis.AfiSafiList]]
        AfiSafiName = "ipv4-flowspec"

But IPv4-unicast safi disabled when I specified flowspec explicitly.

Big challenge with default export filters

Hello!

I'm using GoBGP as client for 2 BGP router servers. And I hit very_popular and ugly issue - I have reannounced all received prefixes from first uplink to the second and vice versa.

So fortunately I have filters on opposite side and I haven;t broken Internet.

So I have multiple questions / suggestions.

First of all, I want to ask to set default export policy to reject or just reject re-announce prefixes received from other uplink to another.

If somebody want it it should explicitly enable this.

I have achieved this with following CLI command:

gobgp global policy export set default reject

But I haven't any idea how to do same with configuration file. Could you help me here?

OpenMessage doesn't contain AS when using `local-as`

Hey!

I am using this simple configuration:

global:
  config:
    router-id: 192.0.2.0
neighbors:
  - config:
      neighbor-address: 192.0.2.1
      peer-as: 64512
      local-as: 65001
  - config:
      neighbor-address: 192.0.2.3
      peer-as: 64512
      local-as: 65002

gobgp is sending an OPEN message without the ASN.

    192.0.2.0.47156 > 192.0.2.1.179: Flags [P.], cksum 0x8a87 (correct), seq 1:46, ack 1, win 229, options [nop,nop,TS val 25941 ecr 60994], length 45: BGP
        Open Message (1), length: 45
          Version 4, my AS 0, Holdtime 90s, ID 192.0.2.0
          Optional parameters, length: 16
            Option Capabilities Advertisement (2), length: 14
              Route Refresh (2), length: 0
              Multiprotocol Extensions (1), length: 4
                AFI IPv4 (1), SAFI Unicast (1)
                0x0000:  0001 0001
              32-Bit AS Number (65), length: 4
                 4 Byte AS 0
                0x0000:  0000 0000

Looking at the code, I am unsure how this should be handled. config/default.go and config/util.go takes the local AS from global configuration only. Other files seem to use LocalAs.

Sometimes API server hasn't started

Hello, folks!

I'm using Git master version of GoBGP and hit this issue multiple times. GoBGP started correctly but did not listen API port:

sudo netstat -lnpt|grep gobgp

I hit this issue multiple times. It's fixed by GoBGP restart:

sudo netstat -lnpt|grep gobgp

Looks likes we have some sort of race condition here...

RPKI walked away after GoBGP update

Hello, folks!

I have RPKI enabled in configuration:

[[rpki-servers]]
  [rpki-servers.config]
      address = "127.0.0.1"
      port = 8282

And it's definitely working:

gobgp rpki server
Session                 State  Uptime     #IPv4/IPv6 records
127.0.0.1:8282          Up     00:40:57   17135/2537

And mentioned in startup code:

{"level":"info","msg":"roa server is connected, 127.0.0.1:8282","time":"2016-01-12T10:14:32+03:00"}

But in gobgp global rib output I do not see any data about RPKI validation status:

gobgp global rib|grep 198068

The same for adj-in output:

 gobgp neig xxx adj-in|grep 198068
    5.45.112.0/24       xxx        3327 198068          00:01:40   [{Origin: i} {Med: 1023}]

But in debug output I see RPKI validation:

{"Key":"xxxx/20","Path":{"IsWithdraw":false,"NoImplicitWithdraw":false,"Validation":"not-found","IsFromZebra":false,"Owner":"xxxxx","Uuid":null},"Topic":"Table","level":"debug","msg":"Implicit withdrawal of old path, since we have learned new path from the same peer","time":"2016-01-12T11:10:11+03:00"}

Could you check this?

Ability to commit all changes in CLI to persistent configuration file

Hello!

I have some idea about "commit" option for CLI which could save all changes executed with CLI to configuration file.

Will be interesting to get example configuration file with CLI (and manually replace it in the filesystem or backup somewhere).

Command gobgp neighbor xxx local hangs

Hello!

I have two servers with standard iBGP configuration.

From second server I have announced some prefix:

gobgp global rib add 10.10.10.0/24

From second server I saw it:

gobgp neighbor
Peer              AS  Up/Down State       |#Advertised Received Accepted
178.62.227.110 65001 00:37:07 Establ      |          0        1        1

So when I tried to get "local" table gobgp get stuck:

gobgp neighbor 178.62.227.110 local
........ so long wait ...

But abj-in works with charm:

gobgp neighbor 178.62.227.110 adj-in
    Network              Next Hop             AS_PATH              Age        Attrs

I have tried -d option but without any success:

gobgp -d neighbor 178.62.227.110 local
... still hangs ...

I could share strace of gobgp process too: https://www.dropbox.com/s/7vl7p69do3jxtcl/gobgp_local.trace?dl=0

Implement more human understandable key names

Hello!

I'm trying to configure default policy for my peers with configuration file. Actually it's bit complicated because you are using 0 and 1 as params for reject and accept here: https://github.com/osrg/gobgp/blob/master/docs/sources/policy.md

My suggestion to change non meaningful 0 and 1 to something like: reject / accept / pass.

BGP filters is very-very-very dangerous part of BGP daemon and we need to prevent as much as possible errors here.

Move away from 8080 port for API

Hello, folks!

I suggest to change 8080 port to something non standard. I hit issue when trying to run RIPE RPKI validator with GoBGP on same machine :)

So much web servers and apps using 8080 port and will be fine to change GoBGP's API port to something uniq!

What do you think?

Bad BGP initial state for neighbour

Hello, folks!

I have started with gobgpd and created following configuration on single server (178...):

[Global]
  [Global.GlobalConfig]
    As = 65001
    RouterId = "178.xxxx"

[Neighbors]
  [[Neighbors.NeighborList]]
    [Neighbors.NeighborList.NeighborConfig]
      NeighborAddress = "213.xxxx"
      PeerAs = 65002

But on the server 213 I haven't started any BGP daemon yet.

But gobgp tool shows it as "active":

gobgp neighbor
Peer               AS Up/Down State       |#Advertised Received Accepted
213.133.111.200 65002   never Active      |          0        0        0

telnet 213.133.111.200 179
Trying 213.133.111.200...
telnet: connect to address 213.133.111.200: Connection refused

What's wrong here? From my point of view we should show it as "down" instead "active".

C/C++ integration issues

Hello!

I have tested my integration with C++ project and found huge amount off issues related with golang .so implementation.

So when we create libgobgp.so we attach full Go's runtime to C++ application. It's not a simple code which could be called like native C .so file.

You could look on example application which linked to libgobgp:

16364 root       20   0  231M 19452 13708 S  0.0  0.1  0:00.03 │        └─ ./gobgp_api_client

16367 root       20   0  231M 19452 13708 S  0.0  0.1  0:00.00 │           ├─ gobgp_api_clien
16366 root       20   0  231M 19452 13708 S  0.0  0.1  0:00.00 │           ├─ gobgp_api_clien
16365 root       20   0  231M 19452 13708 S  0.0  0.1  0:00.01 │           └─ gobgp_api_clien

As you can see we have 5 threads from Golang and only single thread about app itself.

So it's not a problem itself. But Golang runtime redefine all signals and actions and broke popen (they related with SIGCHLD handler code used in pope) capability and daemoization code from my application.

I suggest to create native C library for encoding/decoding BGP structures.... But it's really complex... :(

Very long connection time when GoBGP's peer uses passive BGP

Hello, folks!

My neighbor uses passive mode, so only I could connect to it.

I have following configuration:

 cat /etc/gobgpd.conf 
[global.config]
  as = 65000
  router-id = "136.243.59.116"

[[neighbors]]
  [neighbors.config]
    neighbor-address = "213.133.111.200"
    peer-as = 65000

  [neighbors.ebgp-multihop.config]
    enabled = true

    [[neighbors.afi-safis]]
      afi-safi-name = "ipv4-unicast"

    [neighbors.graceful-restart.config]
      enabled = true
      restart-time = 120

   [neighbors.afi-safis.mp-graceful-restart.config]
        enabled = true

213.133.111.200 it's my neighbor with passive BGP.

But when I start GoBGP I'm expecting immediate connection to neighbor.

But actually I should wait for 50+ seconds until first try to connect with opposite site.

Debug output here:

gobgpd -f /etc/gobgpd.conf --log-level debug

EVPN BGP Encapsulation Extended Community

Is there any way to set the BGP encapsulation extended community attribute on routes ( https://tools.ietf.org/html/rfc5512#section-4.5 ) generated by the "rib add <> -a evpn" commands?

Have you guys discussed about exploring https://tools.ietf.org/html/draft-ietf-idr-performance-routing-00?

Memory leak in Gobgp

Hello!

I'm running gobgp for one week with single unicast peer and got really big memory consumption:

ps aux|grep gobgp

And I'm scary by number of gobgp processes:

        |-gobgpd-+-{gobgpd) S 1 223 
        |        `-36*[{gobgpd}]

Normal usage is about 150 mb:

Issues with route statistics

I haver pretty strange issue with route statistics:

As you can see number of accepted routes exceed number of received routes. How it possible?

Graceful restart capability

Hello!

I have looked to source code and found support for BGP_CAP_GRACEFUL_RESTART. So I'm looking for some way to specify this option.

I want to keep my announces while gobgp is restarting or server with gobgp become unreachable.

More information you could find here:
http://www.juniper.net/techpubs/en_US/junos15.1/topics/concept/bgp-long-lived-graceful-restart.html
https://datatracker.ietf.org/doc/draft-uttaro-idr-bgp-persistence/

So we need two directions:

Option for gobgp client tool for graceful daemon restart
Option for gobgpd.conf for tuning time for timeout for unreachable BGP session.

Could not generate .h file for .so library

Hello!

I have checked master code because I want to pull updated C++ library.

But I could not build .so correctly:

cd /usr/src
git clone https://github.com/osrg/gobgp.git
cd gobgp/gobgp
go build -buildmode=c-shared -o libgobgp.so *.go

But I got only libgobgp.so and could not find libgobgp.h.

So even with old libgobgp.h it do not work correctly:

undefined reference to `decode_path'
undefined reference to `serialize_path'

Could you help me?

Learn routes from Linux routing table

Hello, GoBGP team!

I have idea to use GoBGP for routing between Docker host servers over routing server. I want to deploy Bird as Routing Server and use GoBGP on physical server. So I need two options: add received announces to linux routing table and announce all routes from linux routing table to route server.

I know about some netlink integration in GoBGP. Could you share ideas?

CLI return error

I use gobgp to establish BGP session with two routers:

BGP announcements with timers

Would be great to have the chance of configure timers to BGP announcements in order to be able perform temporal filters with BGP flowspec.

Something like ban an ips address for 1 hour.

Default RPKI server used in GoBGP

Hello!

I saw 210.173.170.254 / 323 RPKI server in your default configuration. What's toolkit are running this server? I have tried to use RPKI validator from RIPE but it's not working.... :(

Extended Communities not serializing into BGP Message

Hi, hopefully it is ok asking a question here. I am new to github. I was looking at this nice project to do something for a research project but am stuck. My problem is trying to serialize "PathAttributeExtendedCommunities".

-I am seeing the serialization in the bgp_test.go trying to use the test message as follows:

&IPv4AddressSpecificExtended{SubType: 3, IPv4: net.ParseIP("192.2.1.2").To4(), LocalAdmin: 3000},
&OpaqueExtended{Value: []byte{0, 1, 2, 3, 4, 5, 6, 7}},
&UnknownExtended{Type: 99, Value: []byte{0, 1, 2, 3, 4, 5, 6, 7}},

I end up with an empty array:

&{{192 BGP_ATTR_TYPE_EXTENDED_COMMUNITIES 0 []} []}

The message looks good in the BGPUpdate message

func (msg *BGPUpdate) Serialize() ([]byte, error) {

Creates:

&{{%!s(uint8=192) BGP_ATTR_TYPE_EXTENDED_COMMUNITIES %!s(uint16=0) } [%!s(*bgp.OpaqueExtended=&{[0 1 2 3 4 5 6 7]})]}

But when the ExtendedCommunity array gets processed further it seems to be empty.

pbuf := make([]byte, 2)
for _, p := range msg.PathAttributes {

The nested Extended Attribute is never triggered:

func (e *OpaqueExtended) Serialize() ([]byte, error) {

Wireshark ends up with an extended attributes structure but it is empty with a length of 0. Thank you for any assistance you can offer.

What about GoBGP's logotype?

Hello, folks!

I'm working hard on my slides for RIPE 71 and I want to mention your awesome toolkit here. But I really like logotypes and will be very happy if you create some logo for GoBGP! :)

Thanks!

GoBGP RFC Support

I intend to compare your OSS BGP Implementation with other ones in my master thesis. I also plan to analyze the implemented features by comparing the supported RFCs.

My issue is that I couldn't find a list of RFCs for GoBGP. I would appreciate if you created a list or posted me the link to the existing one.

External "key" for announces

Hello!

As mentioned in issue #356 so much users want to store additional information for each announce.

So we have two ways:

Store everything in gobgp
Store everything outside

I prefer second option but we need some key for merging data from external storage and gobgp together.

I would like to ask for some way to select announces by ID. With IPv4 unicast is really simple to select announce by key because CIDR mask work as key. But for flow spec announces we should mention whole rule for withdraw.

It's really hard to withdraw announces in full form:

gobgp global rib -a ipv4-flowspec del match destination 10.0.0.0/24 protocol tcp source 20.0.0.0/24 then redirect 10:10

Will be fine to "assign" some uniq key (uuid will be fine) to each flow spec announce for simplified withdrawal process:

gobgp global rib -a ipv4-flowspec del 56beb318-641e-4dd0-8b69-83223f10199a

With uuid's we could store any required information outside without bothering about "key".

Impossible to compile

Testing right now :
$ go get github.com/osrg/gobgp/gobgp

github.com/osrg/gobgp/config

go/src/github.com/osrg/gobgp/config/serve.go:34: v.UnmarshalExact undefined (type *viper.Viper has no field or method UnmarshalExact)

Ability to specify custom nexthop with gRPC or CLI

Hello, folks!

I want to get working nexthop for unicast IPv4 as recommended here #306 (comment)

I have implemented complete API for announce/withdraw prefixes with gRPC: https://github.com/pavel-odintsov/gobgp_api_cpp_client/blob/master/gobgp_api_client.cc#L82

So I could not specify nexthop with gRPC too :(

Because function for generating BGP structures serialize_path hasn't this capability and uses hardcoded nexthop:

gobgp/gobgp/cmd/global.go

Line 398 in ba3a7dd

nexthop = "0.0.0.0"

Could you add any option for doing this job?

I'm using uRPF capability from Cisco and Juniper and really need nexthop... http://www.cisco.com/web/about/security/intelligence/urpf.pdf

Thanks so much!

No new connection is generated when ROA cache is specified with IPv6 address

when formatting url string of ROA cache server in func [email protected], IPv6 address should be enclosed with bracket[]?

No warnings in case of broken configuration options

Hello!

I'm using recent commit and tried to do some tests with it. And hit issue about complete silence about broken configuration options:

[global.config]
  as = xxxx
  router-id = "xxx"
[[neighbors]]
  [neighbors.config]
    neighbor-address = "xxx"
    peer-as = xx 

    [[neighbors.afi-safis]]
      afi-safi-name = "ipv4-unicast"

[[neighbors]]
  [neighbors.config]
    neighbor-address = "xx"
    peer-as = xxx 

    [[neighbors.afi-safis]]
      afi-safi-name = "ipv4-unicast"

    [some.weird.optionsasdadsdas]
      enable = true

[[rpki-servers]]
  [rpki-servers.config]
      address = "127.0.0.1"
      port = 8282

As you can see we definitely should notify user in this case.

But actually GoBGP keep silence:

{"level":"info","msg":"gobgpd started","time":"2016-01-09T20:10:28+03:00"}
{"level":"info","msg":"finished reading the config file","time":"2016-01-09T20:10:28+03:00"}

packet/bgp_test.go cannot find any(?) serialization/decoding bugs

Test_Message() in packet/bgp_test.go is insufficient to find serialization/decoding bugs.

The code creates some random BGP messages and then

serialize the messages
decode the messages
serialize the decoded messages again
compare if the results of serialization in 1 and 3 are the same

What this test can verify is that a BGP message is somehow serializable and decodable,
but it cannot guarantee anything about data integrity.

Therefore this test passes even if a certain field of a message is broken due to a serialization bug.
A sample bug this test cannot find is here: soramichi@5ae7873

To fix this issue requires implementing BGPMessage.equals() that checks if all the field values are the same.

Broken origin for unicats announces with gRPC API and CLI

Hello!

I'm using my C++ code with external call of serialize_path and announce single unicast route. But in CLI client I saw "?" in origin field instead of "i" or "e"

gobgp global rib -a ipv4
    Network             Next Hop             AS_PATH              Age        Attrs
*>  10.10.20.0/22       0.0.0.0                                   00:05:42   [{Origin: ?}]

When I announce unicast route with CLI I got same issue:

gobgp global rib add 11.22.33.44/32 nexthop 0.0.0.0 -a ipv4
*>  11.22.33.44/32      0.0.0.0                                   00:00:04   [{Origin: ?}]

Is it OK?

How to change the BGP server bind address

I think the default local address gobgp used to bind with 179 is localhost, so how can I change the address to another?

thanks.

Install issues on CentOS 6

Hello, folks!

Please read this issue niemeyer/gopkg#36 (comment)

So we have troubles if we want to install gobgpd in CentOS 6 or another old platform. This platform supported by golang but this folks drop support for this really popular platforms.

Do you have any ideas how to solve this issue?

Ability to specify custom community with gRPC API

Hello!

As mentioned before I'm looking for some way to specify custom community with gRPC: #306 (comment) :)

But unfortunately I could generate BGP data structures only with serialize_path function from GoBGP .so library: serialize_path.

For example:

gobgpapi::Path* current_path = new gobgpapi::Path;
path* path_c_struct = serialize_path(ipv4_unicast_route_family, (char*)"10.10.20.33/22");

for (int path_attribute_number = 0; path_attribute_number < path_c_struct->path_attributes_len; path_attribute_number++) {
    current_path->add_pattrs(path_c_struct->path_attributes[path_attribute_number]->value, 
    path_c_struct->path_attributes[path_attribute_number]->len);
} 

current_path->set_nlri(path_c_struct->nlri.value, path_c_struct->nlri.len);

As you can see we could generate PATH only with GoBGP's dynamic library and I could not specify community manually.

So will be fine to open some way to do this because custom community is "must" for me :) Each ISP uses different community numbers for blackhole and I need to use different community numbers each time.

Thanks!

Mistake with array length

Hello!

Please look at line:

gobgp/packet/bgp.go

Line 5941 in d6148c7

if len(data) < 1 {

You are expecting two elements array (because you are reading data[1], second element from data) but you check array length to be more than single byte.

Performance evaluation with BGP Full Table

Hello, folks!

We are interested in performance tests of GoBGP. So we could try to feed FullBGP to it and check how it going.

Do you have any benchmarks?

Detailed information about RPKI status for prefix

Hello, folks!

I'm hardworking on RPKI deployment and have yet another suggestion about it.

I haven't found any ways to check details about RPKI invalid prefixes. Sign "I*>" is not enough for me.

I need something like RIPE RPKI validator REST API output (please look at description field):
curl http://127.0.0.1:8090/api/v1/validity/AS198068/159.253.16.0/24

{
  "validated_route":{
    "route":{
      "origin_asn":"xx",
      "prefix":"xx/24"
    },
    "validity":{
      "state":"Invalid",
      "reason":"as",
      "description":"At least one VRP Covers the Route Prefix, but no VRP ASN matches the route origin ASN",
      "VRPs":{
        "matched":[],
        "unmatched_as":[{
          "asn":"xxx",
          "prefix":"xxx/20",
          "max_length":20
        },{
          "asn":"xx",
          "prefix":"xxx/20",
          "max_length":20
        },{
          "asn":"xx",
          "prefix":"xxx/20",
          "max_length":20
        },{
          "asn":"xxx",
          "prefix":"xxxx/20",
          "max_length":20
        }],
        "unmatched_length":[]
      }
    }
  }
}

Will be fine to get new command to get details about RPKI failed state.

Ask for service name change for gRPC/protobuffers

Hello!

I would like to ask to change standard name for protocol buffers from "api" namespace and "grpc" service name to something more uniq :)

"grpc" and "api" names is very hard to understand because this class names used by gRPC itself or could be used by application authors.

I could offer "Gobgp::GobgpClient" or we could remove package and sue GobgpClient only.

Could not connect together two servers with gobgp due to TTL validation

Hello, BGP Gurus :)

I have installed two servers with gobgp: 178.62.227.110 and 213.133.111.200

I have following configuration files:

Both server correctly listen 179 socket:

netstat -lnpt|grep 179
tcp        0      0 0.0.0.0:179                 0.0.0.0:*                   LISTEN      170307/gobgpd       
tcp        0      0 :::179                      :::*                        LISTEN      170307/gobgpd

And second:

netstat -lnpt|grep 179
tcp        0      0 0.0.0.0:179             0.0.0.0:*               LISTEN      17097/gobgpd        
tcp6       0      0 :::179                  :::*                    LISTEN      17097/gobgpd

I have checked connectivity between servers on 179 port with telnet and everything works nice. But gobgpd do not saw each other :(

Thanks for help!
