>Description:
After the upgrade from FreeBSD 7.4 to 9.1 during system boot statd / lockd report the following errors and do not start:
Apr 3 02:19:45 batman rpc.statd: bindresvport_sa: Address already in use
Apr 3 02:19:45 batman kernel: Starting statd.Apr 3 02:19:45 batman root: /etc/rc: WARNING: failed to start statd

Apr 3 02:19:45 batman kernel: NLM: failed to contact remote rpcbind, stat = 0, port = 0
Apr 3 02:19:45 batman kernel: NLM: failed to contact remote rpcbind, stat = 0, port = 0
Apr 3 02:19:45 batman kernel: Can't start NLM - unable to contact NSM
The same errors are logged when /etc/rc.d/statd is run manually:
Apr 3 02:21:18 batman rpc.statd: bindresvport_sa: Address already in use
Apr 3 02:21:18 batman root: /etc/rc.d/statd: WARNING: failed to start statd
Relevant configuration in /etc/rc.conf (two interfaces, one with multiple IP addresses):
# IPv4
ifconfig_em0="inet 62.12.173.2 netmask 255.255.255.224"
ifconfig_em0_alias0="inet 192.168.1.2 netmask 255.255.255.0"
ifconfig_em0_alias1="inet 62.12.173.11 netmask 255.255.255.255"
ifconfig_em1="inet 62.2.85.178 netmask 255.255.255.240"
defaultrouter="62.12.173.1"
gateway_enable="YES"
# IPv6
ip6addrctl_policy="ipv6_prefer"
ipv6_ipv4mapping="YES" # Set to "YES" to enable IPv4 mapped IPv6 addr communication. (like ::ffff:a.b.c.d)
ifconfig_em0_ipv6="inet6 2001:8a8:1005:1::2 prefixlen 64"
ifconfig_em0_alias2="inet6 2001:8a8:1005:1::11 prefixlen 64"
ifconfig_em1_ipv6="inet6 2001:8a8:1005:2::178 prefixlen 64"
ipv6_defaultrouter="2001:8a8:1005:1::1"
ipv6_gateway_enable="YES"
# IPv6 6to4 gateway
stf_interface_ipv4addr="62.12.173.2"
# IPv6 router advertisement
rtadvd_enable="YES"
rtadvd_interfaces="em0 em1"
# NFS
rpcbind_enable="YES"
nfs_client_enable="YES"
rpc_lockd_enable="YES"
rpc_lockd_flags="-p 4045"
rpc_statd_enable="YES"
rpc_statd_flags="-p 4046"
With the following workaround I could start statd / lockd manually:
sysctl net.inet6.ip6.v6only=0
/etc/rc.d/statd start
/etc/rc.d/lockd start
sysctl net.inet6.ip6.v6only=1
And statd / lockd are running as they should:
root@batman:~ # rpcinfo -p

100000 4 tcp 111 rpcbind
100000 3 tcp 111 rpcbind

100021 3 tcp 4045 nlockmgr
100021 4 udp 4045 nlockmgr
100021 4 tcp 4045 nlockmgr
root@batman:~ # netstat -an |grep 4045

tcp6 0 0 *.4045 *.* LISTEN

root@batman:~ # netstat -an |grep 4046

tcp6 0 0 *.4046 *.* LISTEN
udp4 0 0 *.4046 *.*
udp6 0 0 *.4046 *.*
root@batman:~ #
For a test I remove (disable) the rpc_statd_flags and rpc_lockd_flags lines in /etc/rc.conf, so that a random port is used. But then statd / lockd was only listening on IPv4 and not on IPv6.
>How-To-Repeat:
Set the following options in /etc/rc.conf (with IPv6 enabled and configured):
ipv6_ipv4mapping="YES"
rpcbind_enable="YES"
nfs_client_enable="YES"
rpc_lockd_enable="YES"
rpc_lockd_flags="-p 4045"
rpc_statd_enable="YES"
rpc_statd_flags="-p 4046"
and reboot, or use the following commands:
sysctl net.inet6.ip6.v6only=1
/etc/rc.d/statd start
