It only happens with the implicitly generated ::1/128 address on the loopba= ck interface. If ::1/128 has been assigned explicitly (see examples below), no message is logged. The issue applies to the host system (running the 12.1-RELEASE generic kernel) as well as vnet jails. Here is how to reproduce the issue: On the host system: ifconfig lo0 inet6 ::1/128 delete # after boot, error logged ifconfig lo0 inet6 ::1/128 ifconfig lo0 inet6 ::1/128 delete # no error logged In a jail: # Reproducing the error jail -c -n failjail vnet persist jexec failjail ifconfig lo0 up jexec failjail ifconfig lo0 inet6 ::1/128 delete # error logged jail -r failjail # Avoiding the error jail -c -n okjail vnet persist jexec okjail ifconfig lo0 inet6 ::1/128 # don't use 'up' jexec okjail ifconfig lo0 inet6 ::1/128 delete # no error logged jail -r okjail --=20 You are receiving this mail because: You are the assignee for the bug.=
