Created attachment 226282 [details] core.txt After upgrading to 13.0-RELEASE my host panics when I try to open a http connection to a jail (or opening a connection from the jail) . I'm using vxlan to separate my networks, worked great on 12.x. the problem seems to occur here: https://cgit.freebsd.org/src/tree/sys/amd64/include/pcpu_aux.h?id=5e921ff49ea8bb70506248a4675894729cdad8c2#n55 line 55 Core.txt attached, additional Info https://forums.freebsd.org/threads/kernel-panic-after-upgrade-to-freebsd-13.81044/
Please describe your setup in sufficient detail to reproduce it. The core file suggests that you've created or wound up in a traffic loop, which is resulting in a stack overflow. That's not something we can debug without understanding your setup.
I'll try to describe my Setup as good as I possible: I have one physical IF connected, it's called em0. I have 2 vxlan interfaces, endpoint is my router ifconfig_em0="inet 192.168.1.5 netmask 255.255.255.0 mtu 4000" create_args_vxlan43="vxlanid 43 vxlanlocal 192.168.1.5 vxlanremote 192.168.1.1" ifconfig_vxlan43="inet 10.43.0.5 netmask 255.255.255.0 up" create_args_vxlan44="vxlanid 44 vxlanlocal 192.168.1.5 vxlanremote 192.168.1.1" ifconfig_vxlan44="inet 10.44.0.5 netmask 255.255.255.0 up" therefore I have to use fibs to have several routing tables, they are pretty simple setfib 1 route add -net 10.44.0.0/24 -iface vxlan44 setfib 2 route add -net 10.43.0.0/24 -iface vxlan43 # Default route setfib 1 route add default 10.44.0.1 setfib 2 route add default 10.43.0.1 furthermore I use bhyve based virtual machines in my setup, they are connected to the vxlan interfaces and work just fine. NAME TYPE IFACE ADDRESS PRIVATE MTU VLAN PORTS phcn standard vm-phcn - no - - vxlan43 DMZ standard vm-DMZ - no - - vxlan44 the problem starts with the jail that are connected to vxlans, for example this one: cat /zroot/iocage/jails/phcn-zabbix/config.json { "boot": 0, "depends": "psql", "exec_fib": "2", "host_hostname": "phcn-zabbix", "host_hostuuid": "phcn-zabbix", "ip4_addr": "lo1|127.0.1.10/8,vxlan43|10.43.0.10/24", "jail_zfs_dataset": "iocage/jails/phcn-zabbix/data", "last_started": "2021-07-07 10:06:19", "release": "12.2-RELEASE-p6" }# when I try to connect to the zabbix webui, or if I use the jail console to curl www.google.de the host crashes.
^Triage: clear stale flags. To submitter: is this still a problem on supported versions of FreeBSD?
(In reply to Mark Linimon from comment #3) Hi, I have no idea if that would still happen, could not live with that issue and switched to another OS as my hypervisor. If no one was ever able to replicate it, i guess the report can be closed? Best Regards
