Thanks, that looks like an issue with slists. We had similar issue with
lists code in the past and reworked them to be more conservative. Will
check that.
Great, thanks. If you want to make any changes on a branch or something, I
can build it and test it on my hardware if it would help.
Hi

Just wondering if you do not have the original core dump and binary, or
if you could replicate the issue with unpatched bird. Nick Hainke brought
this issue back on my radar and i would like to find the proper bugfix.
Alternatively, if you still have the configuration, I can try to reproduce the issue.

Hi, the below is the config I am currently using, which I think is more or less the same as the one that was exposing the problem.

I can try to reproduce the issue again and get the core dump again, it’ll take me some time though.

log syslog all;

# debug protocols all;


router id 192.168.55.1;


protocol device {

}


protocol kernel kernel4 {

ipv4 {

export all;

};

}


protocol kernel kernel6 {

ipv6 {

export all;

};

}


protocol ospf v2 ospf4 {

ipv4 {

import filter {

                if ospf_router_id ~ [192.168.30.1] ||

                   ospf_router_id ~ [192.168.25.1] ||

                   ospf_router_id ~ [192.168.54.1] ||

                   ospf_router_id ~ [192.168.20.1]

                then

                   accept;

                else

                   reject;

                };

export all;
