Hi John,
one more thing that I noticed. It seems that the netmask passed to the
procedure rt_maskedcopy is invalid. Cannot dereference the pointer.
I went one frame up and I've looked at the control flow of the parent
routine rtrequest1_fib. This routine passes the netmask, but before it
does that it went with req=11 (RTM_RESOLVE) through this piece of code:
/usr/src/sys/net/route.c:985
case RTM_RESOLVE:
if (ret_nrt == NULL || (rt = *ret_nrt) == NULL)
senderr(EINVAL);
ifa = rt->rt_ifa;
/* XXX locking? */
flags = rt->rt_flags &
~(RTF_CLONING | RTF_STATIC);
flags |= RTF_WASCLONED;
gateway = rt->rt_gateway;
if ((netmask = rt->rt_genmask) == NULL)
flags |= RTF_HOST;
goto makeroute;
Is this a locking problem?
