Bug ID: 268377
Summary: jail -cr <jail> fails to set ipv6-address alias with
ifconfig under certain conditions
Product: Base System
Version: 13.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
I have a jail-Configuration in /etc/jail.conf:
testjail {
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.clean;
host.hostname = "testjail";
path = "/VMs/jails/$name";
interface = "msk0";
ip6.addr = "fd9e:21a7:a92c:2323::1/40";
mount = "/tmp $path/tmp nullfs rw 0 0";
}
If I start the jail with
jail -c testjail
-> No problem
If I stop the jail with
jail -r testjail
-> No problem
If I restart a running jail with
jail -cr testjail
-> I get following error:
testjail: run command: /sbin/ifconfig msk0 inet6 fd9e:21a7:a92c:2323::1/40 >
alias
ifconfig: >: bad value
jail: testjail: /sbin/ifconfig msk0 inet6 fd9e:21a7:a92c:2323::1/40 > alias:
failed
There's a invalid character ('>') in the ifconfig line.
Where it come from? I don't know.
The failure will not occur if I delete the "mount"-Line from the Configuration
(It doesn't matter have a 'mount'-Line or 'mount.fstab').
The failure will also not occur if I append the ifconfig-Parameter
'description' at the end of 'ip6-addr' like:
ip6.addr = "fd9e:21a7:a92c:2323::1/40 description a";
And the failure will only happen with ip6.addr
The same with ip4.addr is not a problem.
It seems to me there is a problem with string handling in the jail command.
