devel/jenkins port not starting. Kernel panic in IPv6 multicast code

[Craig Rodrigues]

Hi,

Sorry for the cross-posting, but I'm not 100% sure where the problem
is, either with the Jenkins port, Java, or FreeBSD networking code..

I recently tried to install the devel/jenkins port
on two separate boxes:


(1)  box 1 running FreeBSD-9-STABLE.

(2)  box 2 running running FreeBSD-CURRENT r254815

On box 1 when I tried to run jenkins with "service jenkins start",
I got a Java error with backtrace:
WARNING: Failed to advertise the service to DNS multi-cast

(see attached jenkins.log.txt)


On box 2, since I this is a debug kernel with WITNESS and INVARIANTS
enabled, I get a kernel panic.  (see attached core.txt.gz)

The panic occurs here on line 1779:

   1768 static struct ifnet *
   1769 in6p_lookup_mcast_ifp(const struct inpcb *in6p,
   1770     const struct sockaddr_in6 *gsin6)
   1771 {
   1772         struct route_in6         ro6;
   1773         struct ifnet            *ifp;
   1774
   1775         KASSERT(in6p->inp_vflag & INP_IPV6,
   1776             ("%s: not INP_IPV6 inpcb", __func__));
   1777         KASSERT(gsin6->sin6_family == AF_INET6,
   1778             ("%s: not AF_INET6 group", __func__));
   1779         KASSERT(IN6_IS_ADDR_MULTICAST(&gsin6->sin6_addr),
   1780             ("%s: not multicast", __func__));

If I look at gsin6->sin6_addr inside kgdb,
I see:

(kgdb) p gsin6->sin6_addr
$1 = {__u6_addr = {__u6_addr8 =
"\000\000\000\000\000\000\000\000\000\000���M|�", __u6_addr16 = {0, 0, 0,
0, 0, 65535, 19951, 54652}, __u6_addr32 = {0, 0,
      4294901760, 3581693423}}}


I am not so familiar with this part of the networking code.
Can someone recommend where is the best place to fix
this would be?

Thanks.
