BUG: dst underflow (again)

As requested, I updated my kernel to see if the "BUG: dst underflow..." messages disappeared. Alas, they didn't. dmesg and .config from 2.6.9-final attached.

Let me know what additional debugging information I can provide, if any.
The symbol addresses in the dmesg output are all inside the ipv6 module.

Thanks,

Jeff

Would you enable CONFIG_KALLSYMS_ALL, please?

Thanks.

FWIW, I'm seeing loads of these on the kernel that comes with Fedora Core 2, also in the ipv6.ko module. I have 6to4 enabled, if that matters anything.

Jeff/Lennert

Could you turn off netfilter and see if this continues to happen?

Know how to reproduce this? ;->

cheers,
jamal

That's one possible angle, but let's look at the tracepoints more closely.

BTW Lennert, the decoded addresses are extremely helpful. Thanks.

Jeff, could you similarly decode the ones that you seem to get? That would be an incredibly useful datapoint. If you've provided this already, my bad and please point me at where you posted that.

...

The last one is the most interesting. The only dst_release() call that occurs in udpv6_sendmsg() is when xfrm_lookup() returns an error. The semantics of that function are a complete mess (when it errors, it sometimes releases the DST, sometimes does not) and I'll fix that up.

But let me ask, do you have any IPSEC policies in the kernel when these BUGs trigger? If so, I'm pretty sure I know what the problem may be.

I've compiled IPv6 into my router's kernel image, so next time I reboot, I should be able to get at symbol info out of the BUGs a bit more easily.

I know this question wasn't directed at me, but, I do always compile ipsec stuff into my kernel, in addition to netfilter. The relevant options are attached for the curious.

Jeff

P.S. Jamal-- I cannot disable netfilter for a period of time long enough to cause the BUGs to be produced, since that disables my NAT'ing.

Thanks a lot.

Yes, but do you actually install any IPSEC rules into your system?

The only way xfrm_lookup() can ever fall (and call that BUG'ing dst_release() in udpv6_sendmsg()) is if you have at least some IPSEC policies configured.

Something, but not quite. :-) This change you propose adds a leak, you have to modify xfrm_lookup() as well.

I'm mid-way through such changes, but it looks something like this (BTW, note the addrconf.c leak I noticed today as well):

In article <[email protected]> (at Thu, 4 Nov 2004 23:16:18 -0800), "David S. Miller" <[email protected]> says:

Ok, I leave it to you.

--yoshfuji

:-)

RIPE hands out IPv6 address space in chunks of /32, and it will only allocate such a /32 for you if you plan on assigning more than 200 /48's in two years.

They specify that you should assign a /64 to a customer if they only need a single subnet, otherwise you should assign a /48. In order to assign 200 /48's in two years, you have to assign 200 address blocks to people who need at least 2 subnets, so that means you have to assign at least 400 subnets' worth of address space.

If you take the canonical IPv6 subnet to be a /64 and the canonical IPv4 subnet to be a /24, that means you have to assign a block of IPv6 address space that roughly corresponds to a IPv4 /15 in two years in order to get IPv6 address space at all.

I politely told RIPE that I don't think we'll be assigning that much address space any time soon, and the result of that was that our address space request was simply denied ("because it does not comply with current policy.")

As a result of all this nonsense, the ISPs in the Netherlands (and elsewhere) that do supply IPv6 connectivity to their customers resort to the immensely wasteful practise of giving each and every single customer an entire /48 because otherwise they will not have assigned enough address space in two years and risk the wrath of RIPE.

(And there's no way in hell you'll get people to peer with you if you start sending them 2002:xxxx:xxxx::/48 routes :-)

cheers,
Lennert

I'm glad.

IPSEC.. not that I know of. So unless my distro does stuff behind my back, no. How do I make sure?

--L

setkey -DP

Well, xfrm_lookup() is returning an error somehow, that's the only way to execute dst_release() in udpv6_sendmsg(). And xfrm_lookup() only returns errors if IPSEC policies have been configured either globally or locally for the socket.

Full proof from xfrm_lookup():

	policy = NULL;
	if (sk && sk->sk_policy[1])
		policy = xfrm_sk_policy_lookup(sk, XFRM_POLICY_OUT, fl);

Unless socket IPSEC policy has been set via setsockopt(), policy will be NULL here.

	if (!policy) {
		/* To accelerate a bit...  */
		if ((dst_orig->flags & DST_NOXFRM) || !xfrm_policy_list[XFRM_POLICY_OUT])
			return 0;

		policy = flow_cache_lookup(fl, family,
					   policy_to_flow_dir(XFRM_POLICY_OUT),
					   xfrm_policy_lookup);
	}

Unless some IPSEC policies have been installed, flow_cache_lookup() will return NULL, thus policy will be NULL here.

	if (!policy)
		return 0;

And thus we always return zero.

Back in udpv6_sendmsg() we have exactly one dst_release() call which is:

	if ((err = xfrm_lookup(&dst, fl, sk, 0)) < 0) {
		dst_release(dst);
		goto out;
	}

So, Lennert's traces make no sense, since without IPSEC policies installed xfrm_lookup() can never return non-zero.

This could mean memory corruption or some kind, or perhaps something installed some IPSEC policies behind his back, but his setkey -DP command shows that this is not currently the case at least.

I hope Jeff or Lennert get newer traces soon.

Actually, there are other calls to dst_release in udpv6_sendmsg. For example, the inline function ip6_dst_store may call dst_release.

I'm afraid that we really have to audit all dst_release callers, both direct and indirect, as well as all places where dst is stored.

Lennert, could you try to reproduce what I observed at Jeff Garzik's ipv6 gateway, running first:

The md5sum is just a trick, using wc-l gives a false impression because the dmesg output wraps around and stays with just BUG underflow... messages.

Another thing: can you try with IPv6 privacy extensions not built into the kernel/ipv6 module? I couldn't reproduce it here at home, not sure why, but I tried with 2.6.9-final (like Jeff's machine) and with latest Linus BK tree, couldn't reproduce.

The problem (or part of it ;) ) lies in net/ipv6/datagram.c, ip6_datagram_connect and the functions it calls that end up calling dst_release, but I don't know that much this code and I'm almost falling asleep here.

Thanks,

Please note that my traces were made on the Fedora Core 2 kernel ('2.6.8-1.521smp'), where these codepaths all look a bit different.

I'm hoping to try a mainline kernel on one of these boxes soon.

cheers,
Lennert
