ospfd assertion `new_distance <= w->distance' failed
6 answers - 18629 bytes -
Hello,
I have configured a new test router (r3-test) with quagga-devel from CVS
as of January 27th (the later changes doesn't have any influence on
ospfd, as far as I can tell).
The zebra daemon is running without any problems, but when starting
ospfd it consistently crashes after a few seconds with the following
stack trace:
2007/02/04 18:55:45 SPF: Assertion `new_distance <= w->distance' failed
in file ospf_spf.c, line 442, function ospf_spf_add_parent

ospfd.conf and ospfd.log are attached (with passwords and IPs changed).
A quick overview over the network layout follows:
There are 2 network segments connected to this router running SPF:
10.0.1.0/24 and 10.0.4.0/22. 10.0.0.0/24 is used /32 loop-back addresses
on dummy interfaces.
There are two main routers (r2 and r4), the test router that crashed
above (r3-test), and some other routers that interface with other segments.
r2 has IPs 10.0.0.2/32, 10.0.1.2/24, and 10.0.4.2/22.
r4 has IPs 10.0.0.4/32, 10.0.1.4/24, and 10.0.4.4/22.
r3-test has IPs 10.0.0.3/32, 10.0.1.3/24, and 10.0.4.3/22.
r3-test is running Debian Sarge Linux.
Let me know if any further information is needed - I am willing to try
patches etc., and like I said, the crash happens consistently within
seconds after starting ospfd.
Regards,
Anders K. Pedersen

This trace isn't at all informative - however as the asserting
function has only one caller anyway
Let me know if any further information is needed - I am willing to try
patches etc., and like I said, the crash happens consistently within
seconds after starting ospfd.
Could you run ospfd under GDB and when it asserts use the 'up'
command to go up the stack frame of 'ospf_nexthop_calculation' then
type 'list' (i.e. I want to see where in ospf_nexthop_calculation
its calling ospf_spf_add_parent).
Also, could you get logs with 'debug ospf event' set?

I had a look at ospf_spf.c to see, if I could figure out, why it hit the
assertion. It seems that the following code in ospf_spf_next():
/* calculate link cost D. */
if (v->lsa->type == SPF_RUTER_LSA)
distance = v->distance + ntohs (l->m[0].metric);
else /* v is not a Router-LSA */
distance = v->distance;
/* Is there already vertex W in candidate list? */
if (w_lsa->stat == LSA_SPF_NT_EXPLRED)
{
/* prepare vertex W. */
w = ospf_vertex_new (w_lsa);
w->distance = distance;
/* Calculate nexthop to W. */
if (ospf_nexthop_calculation (area, v, w, l))
pqueue_enqueue (w, candidate);
}
for (v->lsa->type != SPF_RUTER_LSA) && (w_lsa->stat ==
LSA_SPF_NT_EXPLRED) conflicts with ospf_spf_add_parent() (called via
ospf_nexthop_calculation() above):
new_distance = v->distance + ntohs (l->m[0].metric);
/* We shouldn't get here unless callers have determined V(l)->W is
* shortest / equal-shortest path.
*/
assert (new_distance <= w->distance);
where new_distance is unconditionally calculated as ospf_spf_next()
would have done for (v->lsa->type == SPF_RUTER_LSA).
My understanding of the code isn't good enough to tell which of the two
functions is right, but I'm hoping that the above will help get the
problem fixed.

Sighage, of course yes. the ospf_spf_next() way is correct.
I've attached a patch to CVS which should fix this regression, by
passing down 'distance' from ospf_spf_next and avoiding the
replication. I've expanded the comment for
ospf_spf_nexthop_calculation()
Can you test and verify?
Thanks for root-causing the problem!

Grr, forgot to set root vertex distance. Fixed in attached patch.

Sorry for the delay - I have just had a chance to test this, and it does
indeed fix the problem.
For the record, I first made a few attempts with the old version to
ensure that the problem was still reproducible there, which it was. I
then updated to the current CVS version of quagga-devel, which was
started and restarted a few times without any problems.
Thank you very much.
