System: FreeBSD flappie.debank.tv 7.1-STABLE FreeBSD 7.1-STABLE #0: Wed Feb 18 01:52:24 CET 2009 root@flappie.debank.tv:/usr/obj/usr/src/sys/FLAPPIE amd64


>Description:
	rpcbind fails to start in a jail with only one ipv4 address assigned on amd64 (no other platform available for testing)

>How-To-Repeat:
	Install 7.1-STABLE to a version after the multiple ip jail changes
	Start rpcbind, it fails with "Segmentation fault (core dumped)"
>Fix:

	As a workaround I disabled udp6 and tcp6 in /etc/netconfig, rpcbind works fine now, the last part of a "ktrace rpcbind" is shown below

13860 rpcbind  GIO   fd 7 wrote 70 bytes
       "<27>Feb 18 03:55:12 rpcbind: cannot bind ::1 on udp6: Invalid argument"
 13860 rpcbind  RET   sendto 70/0x46
 13860 rpcbind  CALL  socket(PF_INET6,SOCK_DGRAM,IPPROTO_UDP)
 13860 rpcbind  RET   socket 8
 13860 rpcbind  PSIG  SIGSEGV SIG_DFL
 13860 rpcbind  NAMI  "rpcbind.core"
