The patch provided by BMS looked exactly like the one on the security
advisory, thus I have not applied it.
Due to the fact that this machine was not patched but was cvsup(RELENG_4_8),
and not being able to route to any cvsup server I had to manually update
if_ether.c
Changed;
----- snip -----
if (why) {
if (create)
log(LOG_DEBUG, "arplookup %s failed: %s\n",
inet_ntoa(sin.sin_addr), why);
/* If there are no references to this route, purge it */
if (rt->rt_refcnt <= 0 &&
(rt->rt_flags & RTF_WASCLONED) != RTF_WASCLONED) {
rtrequest(RTM_DELETE,
(struct sockaddr *)rt_key(rt),
rt->rt_gateway, rt_mask(rt),
rt->rt_flags, 0);
}
return (0);
}
return ((struct llinfo_arp *)rt->rt_llinfo);
}
----- snip -----
To;
----- snip -----
if (why && create) {
log(LOG_DEBUG, "arplookup %s failed: %s\n",
inet_ntoa(sin.sin_addr), why);
return 0;
} else if (why) {
return 0;
}
return ((struct llinfo_arp *)rt->rt_llinfo);
}
----- snip -----
I then recompiled and installed kernel. Network seems to be back in order,
with reverted if_ether.c. I suppose I've violated my src tree with this
edit(4.8-RELEASE-p8 with older if_ether.c), so I'll cvsup ASAP for the
correct fix.
Thanks for the help!
