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"
