--- Comment #9 from SATO 'paina' Taisuke <pa...@paina.jp> ---
Hi,
I've encountered the same problem on 12.1R and found a workaround.
The log shown below is how to reproduce the problem using qjail(8).
It's easy like xsan described, stopping VIMAGE jail by qjail.
root@pcv01:~ # uname -a
FreeBSD pcv01.sagamihara.i.paina.net 12.1-RELEASE-p2 FreeBSD 12.1-RELEASE-p2
GENERIC amd64
root@pcv01:~ # pkg info | grep ^qjail
qjail-5.4 Utility to quickly deploy and manage jails
root@pcv01:~ # qjail create -4 10.8.0.128 test001
Successfully created test001
root@pcv01:~ # qjail config -w vmx0 -v none test001
Successfully enabled vnet.interface for test001
Successfully enabled vnet for test001
root@pcv01:~ # qjail start test001
Jail successfully started test001
root@pcv01:~ # qjail stop test001
(crash!)
I'm using 12.1R on VMware ESXi and the virtual NIC is vmx(4).
And I've found the system crashes when qjail try to destroy epairNa interface,
so I've put 'sleep 1' to qjail before the destruction like:
*** /usr/local/bin/qjail.ORG Wed Mar 4 20:13:14 2020
--- /usr/local/bin/qjail Wed Mar 11 01:16:33 2020
***************
*** 2350,2355 ****
--- 2350,2356 ----
# Disable vnet jails network configuration.
#
vnetid=`echo -n "${vnet}" | awk -F "|" '{print $2}'`
+ sleep 1 # XXX: workaround
ifconfig epair"${vnetid}"a destroy
# If host has no more vnet jails then disable bridge.
It seems to happen when destroying epairNa just after killing(stopping) jailed
process.
Therefore, it can be reproduced by commands like:
# jail -q -f /usr/local/etc/qjail.config/test001 -r test001; ifconfig epair1a
destroy
I'm not well on FreeBSD development, so I can't solve the problem alone.
I hope somebody will fix it on future releases.
Thanks!
