Problems with ifconfig when starting all jails after 10.3 -> 10.4 upgrade

[Marc Branchaud]

Hi all,

I just upgraded from 10.3 to 10.4, and "/etc/rc.d/jail start" is having 
problems starting all of my jails:

# /etc/rc.d/jail start
Starting jails:xipbuild_3_3: created
ifconfig:: bad value
jail: xipbuild_3_3_8: /sbin/ifconfig lo1 inet 10.1.1.38/32 alias: failed
xipbuild_3_4: created
ifconfig:: bad value
jail: xipbuild_4_0: /sbin/ifconfig lo1 inet 10.1.1.5/32 alias: failed
xipbuild: created
xipbuild_4_9: created
ifconfig:: bad value
jail: xipbuild9: /sbin/ifconfig lo1 inet 10.1.1.209/32 alias: failed
.

This worked fine in 10.3.  I can individually start each jail, e.g. 
"/etc/rc.d/jail start xipbuild9".

All the jails configure the same set of parameters.  Here's my jail.conf:

--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---
xipbuild_3_3 {
   path="/usr/build-jails/jails/3.3";
   host.hostname="xipbuild_3_3";
   ip4.addr="10.1.1.3/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/3.3/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild_3_3_8 {
   path="/usr/build-jails/jails/3.3.8";
   host.hostname="xipbuild_3_3_8";
   ip4.addr="10.1.1.38/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/3.3.8/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild_3_4 {
   path="/usr/build-jails/jails/3.4";
   host.hostname="xipbuild_3_4";
   ip4.addr="10.1.1.4/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/3.4/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild_4_0 {
   path="/usr/build-jails/jails/4.0";
   host.hostname="xipbuild_4_0";
   ip4.addr="10.1.1.5/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/4.0/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild {
   path="/usr/build-jails/jails/latest";
   host.hostname="xipbuild";
   ip4.addr="10.1.1.200/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/latest/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild_4_9 {
   path="/usr/build-jails/jails/4.9";
   host.hostname="xipbuild_4_9";
   ip4.addr="10.1.1.90/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/4.9/usr/home nullfs rw 0 0";
   interface="lo1";
}
xipbuild9 {
   path="/usr/build-jails/jails/latest9";
   host.hostname="xipbuild9";
   ip4.addr="10.1.1.209/32";

   allow.chflags;
   allow.mount;
   mount.devfs;

   persist;

   mount="/usr/home  /usr/build-jails/jails/latest9/usr/home nullfs rw 0 0";
   interface="lo1";
}
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---

I use ipnat to give the jails network access.  Here's ipnat.rules:

--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---
map em0 10.1.1.0/24 -> 0/32 proxy port ftp ftp/tcp
map em0 10.1.1.0/24 -> 0/32
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---

And here's my rc.conf:

--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---
# Generated by Ansible

# hostname must be FQDN
hostname="devastator.xiplink.com"

# Set rules in /etc/ipnat.rules

# Set interface name for ipnat
network_interfaces="${network_interfaces} lo1"

# Each jail needs to specify its IP address and mask bits in ipv4_addrs_lo1
ipv4_addrs_lo1="10.1.1.1/32"

jail_chflags_allow="yes"

varmfs="NO"
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< ---

Any insight would be deeply appreciated!
