Where is ./bootstrap.sh coming from?

Hi I am tyring to build a Docker image for FRR using https://github.com/FRRouting/frr/blob/master/docker/ubuntu20-ci/Dockerfile. When it gets to line 55, it fails on ./bootstrap/.sh. I have manually inspected the Dockerfile and it seems that the only thing that would write anything to /home/frr/frr is the libyang build. But that isn't producing any file by that name. I tried manually building libyang, too. Where is bootstrap.sh supposed to come from? Thanks and best regards -- Saqib Ilyas

Error with Ansible - socket_path must be a value
by Saqib Ilyas 14 Jul '21

14 Jul '21

Hi I have started a few FRR containers using containerlab. From the host running the container, I can ping the router just fine. Then, I try to interact with the router using Ansible. When I use the facter module, things work just fine. However, when I use the Ansible frr.frr module, I get the following error: An exception occurred during task execution. To see the full traceback, use -vvv. The error was: AssertionError: socket_path must be a value fatal: [172.20.20.4]: FAILED! => {"changed": false, "module_stderr": "Traceback (most recent call last):\n File \"/root/.ansible/tmp/ansible-tmp-1626187837.4416695-33984649570835/AnsiballZ_frr_facts.py\", line 102, in <module>\n _ansiballz_main()\n File \"/root/.ansible/tmp/ansible-tmp-1626187837.4416695-33984649570835/AnsiballZ_frr_facts.py\", line 94, in _ansiballz_main\n invoke_module(zipped_mod, temp_path, ANSIBALLZ_PARAMS)\n File \"/root/.ansible/tmp/ansible-tmp-1626187837.4416695-33984649570835/AnsiballZ_frr_facts.py\", line 40, in invoke_module\n runpy.run_module(mod_name='ansible_collections.frr.frr.plugins.modules.frr_facts', init_globals=None, run_name='__main__', alter_sys=True)\n File \"/usr/lib/python3.8/runpy.py\", line 207, in run_module\n return _run_module_code(code, init_globals, run_name, mod_spec)\n File \"/usr/lib/python3.8/runpy.py\", line 97, in _run_module_code\n _run_code(code, mod_globals, init_globals,\n File \"/usr/lib/python3.8/runpy.py\", line 87, in _run_code\n exec(code, run_globals)\n File \"/tmp/ansible_frr.frr.frr_facts_payload_0vramok4/ansible_frr.frr.frr_facts_payload.zip/ansible_collections/frr/frr/plugins/modules/frr_facts.py\", line 425, in <module>\n File \"/tmp/ansible_frr.frr.frr_facts_payload_0vramok4/ansible_frr.frr.frr_facts_payload.zip/ansible_collections/frr/frr/plugins/modules/frr_facts.py\", line 410, in main\n File \"/tmp/ansible_frr.frr.frr_facts_payload_0vramok4/ansible_frr.frr.frr_facts_payload.zip/ansible_collections/frr/frr/plugins/modules/frr_facts.py\", line 134, in __init__\n File \"/tmp/ansible_frr.frr.frr_facts_payload_0vramok4/ansible_frr.frr.frr_facts_payload.zip/ansible_collections/frr/frr/plugins/module_utils/network/frr/frr.py\", line 18, in get_capabilities\n File \"/tmp/ansible_frr.frr.frr_facts_payload_0vramok4/ansible_frr.frr.frr_facts_payload.zip/ansible/module_utils/connection.py\", line 121, in __init__\nAssertionError: socket_path must be a value\n", "module_stdout": "", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1} An exception occurred during task execution.

However, I can't seem to ssh into the FRR router. Could that be the reason? How do I fix it? Thanks and best regards -- Saqib

isis_tlvs.c : bugs in unpack_item_ext_subtlvs()
by himanshu sardana 10 Jun '21

10 Jun '21

Hi FRR team, File: https://github.com/FRRouting/frr/blob/master/isisd/isis_tlvs.c In unpack_item_ext_subtlvs() there are few sub-tlvs whose unpacking need to be fixed. Basically 2 fixes are required: 1. Default length of sub-tlvs are not correct 2. If length is not as per standard, then pointer has to be advanced to the length value. In below example, these 2 fixes are tagged as FIXME#1 and FIXME#2 For example: unpack_item_ext_subtlvs() { . . . . . . case ISIS_SUBTLV_MM_DELAY: if (subtlv_len != ISIS_SUBTLV_DEF_SIZE) { // FIXME#1: As per standard this is 8 byte sbuf_push(log, indent, "TLV size does not match expected size for Min/Max Link Delay!\n"); // FIXME#2: Advance the pointer to subtlv_len i.e. uncomment below line and add it in the code // stream_forward_getp(s, subtlv_len); } . . . . . . } Note: In unpack_item_ext_subtlvs(), there are other "case" as well that needs the same 2 fix Thanks, Himanshu Rai

bgp6 routes out of sync with kernel (7.2.1)
by Rudy Rucker 09 Jun '21

09 Jun '21

I was seeing an odd issue where some IPv6 routes (mostly google) were not working in our network. We have two Arista edge routers and one FRR edge. Logging into bgpd, I shutdown all the bgp IPv6 sessions and then started them back up and our routing issue went away. We were running 7.2.1 and have since upgraded to 7.5.1 on FreeBSD 12.2. Uptime had been a while on the box and we were not even thinking about it (one of the reasons I like FRR). I didn't see anything odd in the logs. What would cause the FIB and bgpd demon to get out of sync? Other than shutting and restarting sessions is there a process that can validate kernel routes? Thanks, Rudy

I think you're saying you want to allocate bandwidth to various services like VOIP. I'm just a newbie but I didn't see parameters for that in frr. You might be interested in my insights about handling that issue. Very quick summary: make sure VOIP gets priority to go out, but don't allocate; send out packets from the hog flows whenever there's nothing waiting in the quick response categories. Which are recognized not by their port, but because their bandwidth is low. https://www.jfcarter.net/~jimc/documents/voip-qos-1609.html -- James F.

Using Northbound gPRC to configure BGP
by xingyeping＠163.com 02 Jun '21

Hi All. I'm trying to configure BGP with Northbound gPRC. I'm using a Golang client to send Json format configuration to BGPD and now I can send some configuration to BGPD，the question is I can't configure the "afi-safis"。The configuration is underneath： { "frr-routing:routing": { "control-plane-protocols": { "control-plane-protocol": [{ "type": "frr-bgp:bgp", "name": "bgp", "vrf": "default", "frr-bgp:bgp": { "global": { "local-as": 100, "router-id": "2.2.2.2", "afi-safis": { "afi-safi": [{ "afi-safi-name": "frr-routing:ipv4-unicast", "frr-routing:ipv4-unicast": { "network-config": [{ "prefix": "192.168.155.0/24" }, { "prefix": "192.168.166.0/16" }] } }] } }, "neighbors": { "neighbor": [{ "remote-address": "4.4.4.4", "neighbor-remote-as": { "remote-as-type": "as-specified", "remote-as": 100 } }] } } }] } } } The red part can't deliver to BGPD，and the log is： 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [modify] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/global/router-id] value [2.2.2.2] 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [create] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/global/afi-safis/afi-safi[afi-safi-name='frr-routing:ipv4-unicast']] value [(none)] 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [create] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/neighbors/neighbor[remote-address='4.4.4.4']] value [(none)] 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [modify] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/neighbors/neighbor[remote-address='4.4.4.4']/neighbor-remote-as/remote-as-type] value [as-specified] 2021/06/02 08:11:24 BGP: [SWK28-M149C] northbound callback: event [prepare] op [modify] xpath [/frr-routing:routing/control-plane-protocols/control-plane-protocol[type='frr-bgp:bgp'][name='bgp'][vrf='default']/frr-bgp:bgp/neighbors/neighbor[remote-address='4.4.4.4']/neighbor-remote-as/remote-as] value [100] I'm also tried to replace the "network-config" to "frr-bgp:network-config",but it's also does't work. Can anyone tell me the correct json format of "afi-safis"? Regards, Yeping Xing xingyeping(a)163.com

Coredump file with FRR daemons
by jagadeesh N 01 Jun '21

01 Jun '21

Hi All, I'm trying to get the core dump generation in FRR daemons running with non-root user permissions, i sent signal 11 to the daemon process, although stacktrace in the log is printed, the core dump is not generated. After some research I found that, after *PR_SET_DUMPABLE* is enabled, *core dump file is generated* along with that mini dump file is also generated I've few questions related to that 1> Is there a better way to enable core dumps in FRrouting? like any configuration parameters 2> Please point me to code reference where breakpad/crashpad is integrated in FRR Regards, Jagadeesh N
