Windows XP SP3 Causing Router Crashes

KrispyBytes writes "Windows XP SP3 has been named as the culprit causing home routers to go into a crash and reboot cycle. One router maker has released firmware updates to fix the problem, but has not yet revealed what is actually different about XP SP3's networking stack or UPnP behaviour that causes the problem. Router maker Billion Managing Director Raaj Menon said "as Microsoft plans to make Windows XP SP3 an automatic upgrade this month, the number of affected routers may increase significantly.""

Not surprising

[noidentity]

Windows XP SP3 has been named as the culprit causing home routers to go into a crash and reboot cycle.

Not surprising Windows causes that when installed on a router, considering it also makes PCs go into a crash and reboot cycle when installed on them.

Re:Not surprising

[Anonymous Coward]

Lets not jump to blame this on Windows. It could be that Windows isn't doing anything wrong, just something the router should be able to handle, but can't. We can point fingers when we know what the actual issue causing the router problems is.

Ya know I agree, as I've had SP3 installed in one form or another for some time now. With nary a problem... Can't even remember the last time I had to cycle my linksys befsx41. Besides I fail to see why a router should ever be affected to such a degree by a computer on it's network. Really does sound like flawed workmanship.

Re:Not surprising

[thetoadwarrior]

While my router is working fine, my Windows laptop's shares fail to show up on my other machines and this happened straight after installing SP3 and all my settings imply nothing has changed. I just need to get another Windows machine in here to see if it's only being ignored by Linux machines.

Maybe it's a coincidence and maybe it's not. The only way to know for sure is if Microsoft honestly comments on it.

The parent poster shouldn't be modded informative. Their post is a jumble of random network related terminology (several of which have 0 bearing on home routers) into information-less sentences. E.g. *BGP* or IOS on a home router? "Cache tables" (did the poster misremember hearing someone say "hash tables"?). The crowning glory though:

"Spanning tree malformations can do it".

Re:Not surprising

[jibjibjib]

In fact, it's definitely the case that it's something the router should be able to handle. If a router receives a packet that causes it to crash, it's a flaw in the router's software, no matter whether the packet is malformed or not.

Yes, lets not blame Windows XP SP3... after all, this has happened with other OS's and other versions of Windows, right?

Oh, wait, this has only happened with XP SP3 machines....

So, again, what's the probability that it isn't Windows XP SP3 doing something wrong?

I'd say 100% seeing as that it is the router that is crashing.

Think of it this way, if writing this post made your computer crash, would it be my computers fault, or would it be yours?

Well, I'd like to blame it on your computer... and wonderfully, I can - and not be deemed insane. Things like that happen on /. all the time (like the guy I was responding to).

=)

Re:Not surprising

[RobertM1968]

See though, here's the thing... who do you blame?

In a way it is (caused by) SP3... (because) of something the router cannot handle.

So, it raises a few better questions than the ones being raised here (the blame game):

- (ROUTER'S FAULT) Why can't the router handle whatever type of traffic - and should it? At the very least, as a possible attack vector for routers, shouldn't it?

- (NOT NECESSARILY SP3's FAULT, BUT STILL AN ISSUE) Why is SP3 generating such traffic? What type of traffic is it generating? Could this traffic be considered (or detected elsewhere as) a DOS attack of some sort? (We do know that enough SYN packets will crash various routers - even high end ones). What is SP3 actually attempting to do (regardless of HOW, the more important questions are WHAT and WHY).

So, while the router may be at fault for the behavior due to the type of traffic, SP3 is at fault for generating traffic of a nature that is not needed (in any way I can think of) to utilize the Internet... and considering some of the new ad and update and spyware and DRM technologies that MS is trying to bring over to XP (see previous /. articles, various MS patents and more regarding their search plans, "Live" product plans and more)... is this traffic not just flawed, but totally unwanted and intrusive? Or is it simply a screw-up on MS's part that happened to indicate vulnerabilities in various routers?

See the thing is, the reasons MS has such code creating such traffic may be important (or simply a screw-up)... but regardless of that, it showed vulnerabilities in various routers... but regardless of that, it also showed some sort of traffic that SP3 generates that may also be the cause of other routers (that arent affected adversely by such traffic) detecting as an attack of some sort, causing all sorts of other issues (for instance, a subnet or port being shut down to block the traffic).

Think how wonderful that would be if it was at a large company, medical institution, school, EMS station, etc... where all their machines were on a NAT network, and one of them that got upgraded to SP3 suddenly got their single shared IP blocked from the Internet.

So, I think there may be plenty of blame to point at both MS and the router manufacturers...

But the sad thing is, (and I am loathe to say this on /. where I am expected to make judgements based off little or no facts), until enough facts come out (showing what type of traffic, why the traffic is being generated, and what unaffected routers do when they receive the traffic), the only blame so far is:
- MS for doing something (traffic wise) that no other device or OS manufacturer seems to have ever done before.
- The router manufacturers in question for having an implementation that is not robust enough to survive such traffic without crashing.

Before anyone goes on a MS rant

[Gregb05]

A computer on the network should not be able to crash the router. This is a problem with the manufacturing of the routers, not anything in particular with SP3. This problem could have arisen in any OS. The fact that it appeared with SP3 is irrelevant. I return you to your MS bashing.

maybe, maybe not

[frovingslosh]

I agree that no router should crash based just on packets it passes. But there are a few issues here. If SP3 is causing something akin to a DOS, and a router's tables are filling up due to bad packets, it might very reasonably decide that things are so bad that the best thing for it to do is a reset. We don't blame the router maker when an external DOS attack interrupts Internet access, why blame it if the DOS is from Microsoft software on the inside?

And there is also the potential issue of this being UPNP related. UPNP is a completely bogus thing, but Microsoft strong armed the industry to support it and it's in most routers and many users don't know to disable it. UPNP could certainly give ways to cause this issue, and I only hold the router itself responsible to the extent that it supports this blasphemy.

How do you know it's not? Until we see some actual analysis of this, there's no way to know if XP is at fault or if it's just shitty routers doing what they do.

Re:Before anyone goes on a MS rant

[Anonymous Coward]

Lets make this easier and flat out assume XP's UPnP implementation was intentionally designed to crash the largest number of routers on the planet in a clever bid to raise Vista sales.

Even with this unlikely assumption in play it would still be 100% the fault of the router for crashing.

Re:Before anyone goes on a MS rant

[Jugalator]

True but it takes two to tango

Yes, it wouldn't have happened without the "help" of SP3 in this case. That being said, with the relevant information not released here, it's not certain SP3 is doing anything inherently wrong according to the networking standards. Testing SP3 on all hardware configs is additionally nothing one can expect Microsoft of doing.

Re:Before anyone goes on a MS rant

[John Hasler]

Nonsense. Any router that can be crashed by anything that a computer connected to it does has a critical bug and should be recalled immediately.

Exactly

[biolysis]

Your point is the relevant one. Regardless of what OS did this, the fact is that no computer should ever be able to crash a router period. The incessant MS bashing reaches absurd levels sometimes.

Re:Nah...

[cnettel]

If you can crash the router, you have a possible DDoS attack. If you can do it on the WAN port, it would certainly be a flaw in the device. Depending on the crashing behavior, it is also possible that this is actually an exploitable path that could be used to permanently reflash the router for malevolent purposes.

Re:Before anyone goes on a MS rant

[jellomizer]

However... If they find out what causes the router to crash with SP3 then all it will take is someone to duplicate the information sent and crash the router again and again. If the router crashes is has to be the fault of the router not of the OS, as other routers don't crash. As well as a poorly designed website. If your web browser crashes from a badly made website then it is the web browsers faults. Your argument only really holds true in cases of custom designed software where the sender of the data will need to agree to send the data in the correct format as well the receiver agrees to get the data in the correct format. And still even in that case a good program will be able to atleast say something is wrong, vs. it crashing.

Re:Before anyone goes on a MS rant

[Sleepy]

>just like a website should never crash a browser it is relevent that the OS/website is abusing the specifications soo badly to cause the crashes.

All browsers MUST expect garbage input, and pretty much anyone who expects otherwise has their head in the sand, and shouldn't go NEAR code. Document formats don't run in local memory and do not have system access - they're interpreted structures. If a browser crashes, it's the browser's (or it's plugins) fault, 100% of the blame 100% of the time. At worst, you should expect degraded-looking content and that's that.

I don't mean to be snarky, but your argument couldn't be more wrong or inappropriate. With networking, you're pretty close to the physical layer (not a great analogy, but browser code is far removed from traffic and is just a local representation, a user application).

We don't know yet what this is caused by. If it is affecting a lot of routers, it might very well be a "DOS". Or it could be something that holds too many connections open, or IP6 traffic that doesn't go anywhere and ties up the router table till it times out.

This could happen to Linux also, but it's less probable -- it's be code put out in the wild, and the distro's would do their own QA process, and may hold back. Most distros don't run kernel.org kernels, but their own patched tree.

Re:Before anyone goes on a MS rant

[Kjella]

Between having a security hole that allows denial-of-service attacks and sending some slightly mangled packets, I'd go about 98-2% to the router manufacturers on this one. That is assuming the packets are actually mangled, which isn't proven. I wouldn't care how broken a web page was, if Firefox crashes then it's Firefox's fault (or extensions/plugins, but that's a different issue). If you came and said "While it's true that the browser shouldn't crash in any circumstances, Apache would certainly deserve bashing if it's a result of them violating the specs and sending out mangled web pages." I think people would laugh. Assume the input data is crap, that applies equally everywhere and any software that can't handle that is poor software.

Re:Before anyone goes on a MS rant

[postbigbang]

Everyone wants a bulletproof, but quickly reacting app. Sometimes you can't have both. You can build parsers that vet web pages for sanity sake (or just look for malware as some plugins do), but they'll slow down even the fastest clocking machines; the insertion loss of the parser will be like putting a foot on the garden hose.

Routers and layer 2/3 bridges have to react at wire speed, and therefore have lean, racing engine code with only the barest of exception handlers. Inside the code are lots of routines that have to react to protocol changes related to table building. Screw up those tables even legally (according to the obscurities of even well-known protocols) and the routing/bridging device will behave badly, even to the point of apparently not working. It's happened before, and will happen again. Is it XP3? No one knows yet.

The next update of will likely fix the problem; likely it would arrive before a Microsoft fix, and it would be more effective to fix the crashing device than go after all possible XP SP3 users. Sadly, once in the 'wild', it's the router vendor's problem rather than Microsoft's, no matter who is to blame for the original mistake.

Agreed. If SP3 can do this unintentionally, imagine what the series of communicated data with the routers can do if a malicious writer now reverse-engineer whatever SP3 is doing, and would spread a time-triggered virus, for example. These kind of hardware issues are never good.

Both. Windows sends out funky data; that's not optimal and should be fixed (unless it turns out that Microsoft uses an obscure but valid part of some standard). The router can be crashed by sending it funky data; that's a major screwup and shouldn't have happened at all.

Microsoft (maybe) gets a slap on the wrist for not paying attention; the router manufacturers get a kick in the balls for producing junk.

Router Trouble.

[fuzzyfuzzyfungus]

As some have said, if a machine on the network can crash the router(short of violating physical specs for things like ethernet voltage and polarity), then the router has Issues.

What I don't understand is why so many of your basic 4 ports lan, one port wan, and an antenna type routers have such lousy firmware. I understand that the hardware is built right down to price, and isn't going to be exciting; but software is a different matter. There are really only a few chipset variations in general use, OpenWRT supports most of them and provides a solid and extensible foundation. ddWRT is less extensible and flashier, still solid. Tomatoe is out there as well. In a world where people are literally giving high quality router firmware away, how can anybody ship a router with bad firmware?

Crappy router.

[fluffy99]

Billion makes crappy knock-off routers, that were crashing or not working long before XP SP3 was released. Perhaps XPSP3 does do something different with uPNP, but that's not where the blame needs to be assigned. As an aside, uPNP is a crappy idea. Do you really want your OS and any programs (malware included) to have the ability to change your external firewall?

NAPT != Firewall

[Luke-Jr]

uPNP configures port forwarding for a NAPT (aka NAT) router. NAPT/NAT is *not* a firewall, and should not be treated like one. Its sole purpose is to translate addresses and ports (Network Address and Port Translating) between the internal and external networks. It is not meant to protect computers on either end from each other. uPNP facilitates the NAPT job by giving applications an easy way to automate the needed port forwarding for the WAN->LAN direction. If you want a firewall, get a real firewall.

Correlation != causation

[catscan2000]

It sounds like the Billion router's firmware had a really bad bug that happened to be poked by Windows XP SP3. Unless if this was in a third party library or some external code that they were using, I wouldn't be surprised if this was limited to just Billion routers.

XP SP3 didn't _cause_ the bug; it merely happened to recreate a condition that triggered a bug inside the router to crash itself. :-)

[Anonymous Coward]

Quote from their website:

"After detail analysis, we found that Windows XP SP3 sent out the DHCP packet with the Option 43 data (include Microsoft's 'Vendor Specific Information'), but Windows XP SP2 sent out the DHCP packet without the Option 43 data. However, the Option 43 data is not compatible with Billion's original definition, so it will cause this problem. The affected firmware versions of BiPAC 5200 series are 2.9.8.x and 2.11.0.x~2.11.33.x. There is no impact to BiPAC 5200 series if the firmware is 2.10.x.x. Please check Appendix A for checking your current firmware version."

Re:Here's the technical reason

[Richard_at_work]

Just to clarify the parent posters information, Option 43 (Vendor Specific Information) is a valid but optional part of the DHCP spec, covered in RFC 2132, part 8.4. A server not equipped to handle the Vendor Specific Information must ignore it.

Re:Here's the technical reason

[Todd Knarr]

That doesn't make sense, though. Option 43 is sent by the DHCP server to the client. In this case the SP3 machine is the client and the router is the server. It's the server's responsibility to correctly format the vendor-specific data according to the vendor's spec, but the SP3 box shouldn't be the server in the scenario in question.

Re:

[Todd Knarr]

Aha. But it still doesn't make sense. If SP3 is sending option 43 as a client, then the data will be in Microsoft's vendor-specific format, not Billion's. The only way Billion would have a problem is if Microsoft changed the format without telling anyone. And why would a router need to look at Microsoft's vendor-specific information in the first place?

[Krunch]

The client sends a DHCPREQUEST packet that contains options it is requesting from the server. The server is then supposed to craft a DHCPACK packet containing values for the options requested by the client.

Billion's routers crash after upgrade to XP SP3.

OMG a Billion Routers crash....

Not MS to blame

[Opportunist]

As much as I hate defending the Redmond Computer Virus (tm), that's the router's fault.

Now, if SP3 created nonstandard packets that most routers still swallow but a router drops because they don't work to spec, blame MS. If the router replied with a bogus message to said nonstandard packet that locked up XP, blame MS. But a router HAS TO be able to accept a bogus packet. It may drop it, report it or if it feels like it send it on a roundtrip in hope that some machine can figure out what it's about, but it may NEVER crash due to it.

I hope I don't have to mention the security implications of this.

What's worse

[Sycraft-fu]

It sounds like the packet isn't bogus. MS chose to implement an optional part of the DHCP spec (vendor information). As per the DHCP spec if your device doesn't implement the optional parts, you just ignore them, not crash.

So this isn't MS sending a bogus packet, or even doing a "Windows own spec," thing. They are properly following the DHCP spec, and this POS can't handle it. I mean I'll give someone a tiny bit of credit if the problem is due to bad data. Not a lot, it's still a bug that needs to be fixed, but at least it was something unexpected. However when you are crashing because you didn't deal with part of a spec, well then you get zero sympathy.

Speaking Of SP3...

[xanadu-xtroot.com]

Last week I updated my GF's XP_Pro machine to SP3 (she insists on having her machine using Windows despite having a better time using my KDE/Gentoo machine...). Since then, I've noticed that it's sending out SMB keep-alives about every 5 seconds to my machine (which is the Samba "PDC" also). SP2 wasn't doing this (or WireShark didn't pick up on it, anyway).

Could this be something that would hose a router as well? A ton of useless keep-alives?

one model from one manufacturer

[confused one]

This only affects one model (BiPAC 5200) wireless broadband router, from one manufacturer (Billion), who's firmware has a bug. The model in question is found in Australia and Europe. A firmware update is available for download. End of story.

Standards Shell Game?

[Zero__Kelvin]

The consensus seems to be that the router is at fault if SP3 crashes it. There is a major factor that people are overlooking here. uPNP is a M$ "standard." So here is the possible, and I would even assert likely, scenario:

M$ creates the uPNP standard, then revises it, then revises it again. To the extent that it is a standard, different versions of the "standard" are made available to different router designers, based on how close they come to touching their palms to the floor when bending over for M$. Now, those who handed over their first born have the newer tweaked standard available, and if they comply their router doesn't crash. In the meantime, other router companies have a different/older standard, to which they comply fully. Of course, SP3 makes use of the newer, less widely disseminated standard. Doing so causes implementations that haven't "paid up" to crash.

Yes, this definitely sounds like a scenario imagined by a guy who wears a tin-foil hat to those who don't know the M$ history, haven't read the M$ internal documents known as the Halloween Documents [catb.org], etc. To people who know the history and understand how M$ works, this is a likely though unproven scenario.

I have to agree.

I updated to SP3 yesterday, and now my microwave stopped working.

Coincidence? I think not!

Funny, but IMHO Windows' support for USB still sucks. Sometimes my XP Home machine boots up and totally ignores my USB keyboard. Unplugging the kb and plugging it back in fixes the issue temporarily, but why should I have to do that? The motherboard setup program has no such issues, and neither do any Linux distros I've tried.

apples to oranges

[spazdor]

Did the hardware manufacturers all just write flawless Linux drivers and buggy Windows ones?

Or did Linux developers just go a step further than Windows did, and take it upon themselves to make sure that hardware works properly on their OS?

"Second, the USB ports on my HP Port Replicator xb2000 (I believe) no longer function."

Boot a live Linux CD such as Knoppix and see if it works. It's a handy way to swap OS for testing.

For what it is worth, I have no problems with USB or field data with SP3.

Re:

[Ethanol-fueled]

No, it's just the Linux overlords making their stuff not work--on purpose--with Microsoft products. It's a conspiracy to propagate desktop linux since 99% of broadband customers access the net through some kind of cheap router.

...And you all think that Microsoft is anti-competitive? :)

Re:

[John Hasler]

The problem is much more likely to be in code added by the manufacturer, either in their custom device drivers or their application code.

Re:

[SanityInAnarchy]

We all know that most routers use Linux

Do we? I'd guess a fair number don't.

Re:

[anotherone]

Even if that were true (it isn't) it would STILL be the router's fault.

Re:Oh brother...

[spazdor]

is a coincidence, or just completely made up

Unlikely, given that the OP mentions that at least one manufacturer has fixed the problem with a firmware update. You can't really write software to fix a problem until you've figured out what the problem is.

You're right though, a properly hardened router will keep ticking regardless of what's plugged into it. Mostly. [fiftythree.org]

Re:Glad I disabled auto-updates

[afidel]

I'm more glad I disabled uPnP, it's a very poorly designed spec with even crappier real world implementations. It's about the most bug-prone technology I know of.

Re:Glad I disabled auto-updates

[Ihmhi]

Right, until a "critical security update" turns that option right back on. Better to just turn off Automatic Updates and disable Security Center in Administrative Tools > Services so it stops whining about your computer "not being protected".

Re:

[nosfucious]

Good point.

Don't just disable it, remove it from your System. It's just another networking service and it can be un-installed.

Although, as the parent poster mentioned, it's not beyond Microsoft to re-install it as part of a Service Pack/Security Update. (See Windows Messenger).
