Hello, We have been using BIRD 1.6.3 on Ubuntu 16.04 as Route Server for a long time. Recently we decided to implement a ROA check filtration but we're experiencing the daemon is crashing whenever removing roa table from the file config even when the roa table is not applied anywhere. In simple words: The ROA table is only defined in the config. Here is а specific example: root@rs2-lab:/usr/local/bird-new/etc# cat roa.conf roa table r65501 { roa 1.2.3.0/24 max 32 as 65501; } ################################# *Here is our simple bird config:* root@rs2-lab:/usr/local/bird-new/etc# cat bird.conf log "/var/log/bird.log" all; log syslog all; debug protocols { events }; router id 10.10.10.100; define myas = 12345; protocol device {} include "roa.conf"; ################################# So when I remove/comment "roa.conf" from the config - bird process is crashing /root@rs2-lab:/usr/local/bird-new/etc# birdc c// //BIRD 1.6.3 ready.// //Connection closed by server/ *Here is dmesg with the crash info:* /[62285.414645] bird[11272]: segfault at 0 ip 000000000040ace7 sp 00007ffd5040e950 error 4 in bird[400000+74000]// //[62508.998315] bird[11487]: segfault at 0 ip 000000000040ace7 sp 00007ffe148741c0 error 4 in bird[400000+74000]// //[62599.558242] bird[11570]: segfault at 0 ip 000000000040ace7 sp 00007ffdfa129070 error 4 in bird[400000+74000]// //[62649.377296] bird[11575]: segfault at 0 ip 000000000040ace7 sp 00007ffd5d8da0a0 error 4 in bird[400000+74000]// //[63895.137084] bird[11730]: segfault at 0 ip 000000000040ace7 sp 00007ffdd4f08f00 error 4 in bird[400000+74000]// //[63927.053383] bird[11738]: segfault at 0 ip 000000000040ace7 sp 00007ffe9c5c8110 error 4 in bird[400000+74000]// //[66260.552622] bird[13629]: segfault at 0 ip 000000000040ace7 sp 00007ffc58de2ad0 error 4 in bird[400000+74000]// //[69835.274826] bird[14098]: segfault at 0 ip 000000000040ace7 sp 00007ffe306bc640 error 4 in bird[400000+74000]// //[70481.342658] bird[14218]: segfault at 0 ip 000000000040ace7 sp 00007ffd556c04c0 error 4 in bird[400000+74000]// //[70587.636343] bird[14234]: segfault at 0 ip 000000000040ace7 sp 00007ffdbc90e4d0 error 4 in bird[400000+74000]/ Could someone BIRD developer can help on this issue?
