I just upgraded from FreeBSD 11 to 12 and upgrade from quagga to FRR at the same time. I've tried frr6 and frr7 and get the same errors. bgpd and ospfd work fine, but ospf6 doesn't work. Not sure what I'm going wrong. If I commend out all the interfaces EXCEPT lo0, ospf6d does not crash. router ospf6 ospf6 router-id 172.17.18.98 redistribute connected route-map MONKEY-ospf6 redistribute static route-map MONKEY-AND-MORE-ospf6 !interface cxl1 area 0.0.0.0 !interface cxl2 area 0.0.0.0 !interface cxl3 area 0.0.0.0 interface lo0 area 0.0.0.0 As soon as I get routes from my network, ospf6d tanks. Any thoughts? Here is the output from zebra and ospf6. *** LOGS *** 2019/10/10 23:19:31 OSPF6: Scheduling cxl1 for sso 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 0 msec 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 sec 5 usec, Reason: L+ 2019/10/10 23:19:31 OSPF6: Scheduling cxl2 for sso 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 50 msec 2019/10/10 23:19:31 OSPF6: Scheduling cxl3 for sso 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: [Down]->[Init] (HelloReceived) 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: [Init]->[ExStart] (2-WayReceived) 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: [ExStart]->[ExChange] (NegotiationDone) 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: [ExChange]->[Loading] (ExchangeDone) 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 sec 109 usec, Reason: R+, R-, L+ 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 83 msec 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 sec 116 usec, Reason: R+, N+, L+ 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: [Down]->[Init] (HelloReceived) 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: [Init]->[ExStart] (2-WayReceived) 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: [ExStart]->[ExChange] (NegotiationDone) 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: [ExChange]->[Loading] (ExchangeDone) 2019/10/10 23:19:33 OSPF6: SPF: Scheduled in 0 msec 2019/10/10 23:19:33 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 sec 99 usec, Reason: R+, R- 2019/10/10 23:19:36 OSPF6: Neighbor state change 172.17.24.25%cxl3: [Loading]->[Full] (LoadingDone) 2019/10/10 23:19:36 OSPF6: SPF: Scheduled in 0 msec 2019/10/10 23:19:31 ZEBRA: client 32 says hello and bids fair to announce only ospf6 routes vrf=0 2019/10/10 23:19:38 ZEBRA: [EC 4043309117] Client 'ospf6' encountered an error and is shutting down. 2019/10/10 23:19:38 ZEBRA: release_daemon_table_chunks: Released 0 table chunks 2019/10/10 23:19:38 ZEBRA: release_daemon_label_chunks: Released 0 label chunks 2019/10/10 23:19:39 ZEBRA: client 32 disconnected. 100 ospf6 routes removed from the rib *** CRASH *** If I run on the command line and don't background, it bombs after 7 seconds: # ospf6d Illegal instruction Here is the end of truss: # truss ospf6d ... mmap(0x0,4096,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0x0) = 34863378432 (0x81e04f000) mmap(0x0,4096,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0x0) = 34863382528 (0x81e050000) mmap(0x0,4096,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0x0) = 34863386624 (0x81e051000) mmap(0x0,4096,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0x0) = 34863390720 (0x81e052000) SIGNAL 11 (SIGSEGV) code=SEGV_ACCERR trapno=12 addr=0x7fffdffffff8 process killed, signal = 4 I wasn't seeing any CORE files when the process dumped, so I turned this knob: sysctl kern.sugid_coredump=1 Now there is a 1 GByte core file! # /usr/obj/usr/src/amd64.amd64/gnu/usr.bin/gdb/gdb/gdb /usr/local/sbin/ospf6d ospf6d.core (gdb) bt #0 0x000000080030678c in hash_get () from /usr/local/lib/libfrr.so.0 #1 0x000000080033a9b2 in route_node_lookup () from /usr/local/lib/libfrr.so.0 #2 0x0000000000241345 in ospf6_route_lookup () #3 0x000000000022e718 in ospf6_abr_examin_summary () #4 0x000000000022f13b in ospf6_abr_examin_brouter () #5 0x00000000002473ad in ospf6_top_init () #6 0x000000000022efda in ospf6_abr_examin_summary () #7 0x000000000022f13b in ospf6_abr_examin_brouter () #8 0x00000000002473ad in ospf6_top_init () #9 0x000000000022efda in ospf6_abr_examin_summary () #10 0x000000000022f13b in ospf6_abr_examin_brouter () #11 0x00000000002473ad in ospf6_top_init () .... lines #3 - #5 repeat to over #8500 ...
