Crypto and IPSec Merged into 2.5 229

Posted by Hemos from the gettin-it-on dept.
Corbet writes "Linus has just merged the new crypto API and IPSec implementation into his 2.5 BitKeeper tree. This is the first time that serious cryptographic code has made an appearance in the mainline kernel, and it will hopefully lead to more secure communications for all Linux users in the future."

    I really like the way the 2.5 kernel is progressing, a lot of the patches that I've been applying manually to the 2.4 tree have already been merged into the main tree of the 2.5 kernel.

    Can't wait until release, this thing is going to rock. :)

      somewhat, but from what I read bout a week and a half ago... the ipsec impmentation that they are putting in does not yet support ipv4 transport.... ie is useless unless you have hosts fully using ipv6 on both sides of the tunnel. Keep in mind, its not frees/wan, its from the linux ipv6 project.

      With the atitude that the frees/wan project maintains, we will never see freeswan merged with mainstream kernel... hell... they still refuse to take patches from us citiziens and residents (that includes linus)
      • If frees/wan won't take contributions from the US why doesn't someone in the US fork it? Isn't this the way OSS is supposed to deal with stubborn maintainers that have different ideals than a large number of developers?
        • Thats a question I really can't answer. I should have thought about it many months ago when I found routing bugs in frees/wan internal routing table.... when they refused to hear anything about it and claimed it must have been a configuration error..... but I've been using frees/wan for years... since frees/wan 1.3 i think..... I know it inside and out. Perhaps it is time to fork... or wait till FreeS/WAN 2, and fork it. You are right.... it is time to fork it.

          Why no fork yet?

          Because it's a large project, it's really complex, and it's a bitch to keep up with things.

          I should know - I'm the author of Super FreeS/WAN, a pseudo fork with includes alot of patches (NAT-T, X.509 Certs, AES/Blowfish/etc... ) @ http://www.freeswan.ca/code/super-freeswan

          It takes a few hours a day to stay on top of things. One the major ones is user support. IPSec is not easy to configure currently, especially once you introduce X.509 certs & MS Windows clients using any number of clients. So there's hundred of questions about configs, how tos, etc...

          If you want to fork it, please, go ahead. Just remember that a fork isn't just the code - you take users with you.
          • One of the major problems with frees/wan is the documentation. "Oh, you might be able to do this, we dont know.." When it has been posted to the mailing lists, and discussed "oh, Here is how you do it".

            I was going to use your fork, but I lost my job. :( Perhaps I should write a patch that allows for more then one type of network interface so it is easier to sue ospf..... and changing the internal routing table so its more kind to other things such as routing protocols.
            • 2.00 + snapshots, and forthcoming 1.99 have vastly improved docs, and a way better inter-op doc.

              I run OSPF + BGP over FreeS/WAN using GRE, which seems to be the simplest way to do it - there's been alot of dicussion lately on the lists about doing this.

              Sorry to hear about the job loss, but when you get back on your feet and want to continue, just flip me a note and I'll give you a CVS repository if you want to start with.

        • I believe that's kind of what the article is announcing. A fork and Linus likes it enough to include it in his kernel.
      • With the atitude that the frees/wan project maintains, we will never see freeswan merged with mainstream kernel... hell... they still refuse to take patches from us citiziens and residents (that includes linus)

        Considering the US's asinine stance on crypto export, that's just good sense.

        That said, there's no reason the frees/wan code couldn't go into the kernel in a stable form, but still be maintained separately overseas.

      • >With the atitude that the frees/wan project maintains, we will never see freeswan merged with mainstream kernel... hell... they still refuse to take patches from us citiziens and residents (that includes linus)

        Not to mention they refuse to include support for the faster [freeswan.org] (but less secure) type of IPSec, thereby causing me to run Win2k on my router for a short while. I believe they even say it's fully valid to use IPSec in this manner (in fact it's part of the spec, so without it they shouldn't be calling it IPSec, IMHO), but they just don't want to support it in the faq, 100% due to attitude.

        Developers may have a right to any attitude they desire, but they should understand their software is just going to be replaced (in the mainstream) by software from someone with less attitude. Let's hope that's what happens with freeswan. I think we don't need another OSS [4front-tech.com]-style crippled set of kernel software. (Did they move to ALSA [alsa-project.org] yet? I hope so!)

        Just my 2 cents.
        • Not 100% due to the attitude more than anything else. They by default choose not to allow single DES to protect users/organizations from themselves. Tell me a legitimate reason why, with today's hardware, you need only single DES? It is really not that secure in this day and age? In any case, when I set up FreeS/WAN on a system, two sets of patches immediately go on, x509 cetificataes (ala http://www.strongsec.com), and cipher plugins (http://www.irrigacion.gov.ar/juanjo/ipsec/). I usually do AES when going to other patched FreeS/WAN, and use the enhanced 3DES from that suite when dealing with implementation lacking AES...

          AES is truly the way to go. There are a number of aspects of FreeS/WAN where they felt things the standards required to be available were too weak to be secure. They are mostly compliant with the specs, but I agree with them that certain things really have no use in security except to make things easier on organizations like the NSA...

    • Simpler setups for important security features are great and definitely do depend on this infrastructure being in the default kernel distributions. (I kind of like the idea of cryptographic filesystems enabled by default on laptop computers that could stolen.)

      But, as we all know, that's not enough.

      That simple setup has to be exceedingly well-designed so that 2-minute Click-through VPN installations are not left vulnerable due to some trade-off for more convenience.

      Everyone knows and has deservedly berated Microsoft for making poor choices in this matter; let's not have widely-deployed commercial Linux distributions make the same mistake.

          Yes, but it was exactly the same kind of executive decree that made crypto illegal to export to begin with. There is no law in the US that states that crypto is a munition or that it can't be exported.

          At this point, it really just doesn't make sense to hold off on adopting crytpo out of fear that the US is going to surprise everybody and yank our crypto rights out from under us. The cat, as they say, is out of the bag. It won't go back in. The government is welcome to try to re-regulate crypto export, but it won't work. (They actually tried this briefly after 9/11, and the proposals died silently.)

          This news about crypto in the Linux kernel is wonderful. The more crypto is out there, integrated into our daily lives, the harder it will be for somebody to try to take it away from us.

      Uh, calling FreeSWAN a "full" implementation is very misleading. Its IKE does not support Aggressive Mode which is pretty much a requirement for virtually every Hardware IPSEC VPN out there.

      FreeSWAN may be good for crypto, but bad for actually getting your work done. Regardless, the new IPSec code gets the hard part integrated, an ipv4 implementation should be trivial.

      • According to the FreeS/WAN documentation [freeswan.org], Aggressive Mode is not required for an IPSEC implementation, as long as you support Main Mode. Fix those hardware boxes, I'd say. If they don't support Main Mode, are they still IPSEC compliant?

        The only reason I can think of why you want this, is when you have a dynamic IP address and you want to use a Preshared key. Get a fixed IP or start using X.509 certs.

        Aggressive Mode exposes some information, plus it might make DDoS easier to do.

        • >The only reason I can think of why you want this, is when you have a dynamic IP address and you want to use a Preshared key.

          So I see. Basically any home user using an ISP shouldn't expect to ever have any kind of crypto at all because it is slightly weak.

          Next up: Master quits making front door locks. States that most homes have windows and therefore their locks are ineffective, so they will quit selling them altogether.

          A lack of Agressive Mode (among other things) is the _only_ reason my previous ISP didn't support Linux. In fact, they wanted to support Linux, and eventually switched over to a non-encrypted system and released a Linux client for it.

          So, who really wins in the end? Nobody. Ho hum.

      While I appreciate all the work that freeswan has done for us, I am much more confident for the long term in work done by the core Linux networking hackers. The freeswan guys seem much more concerned with making it work (in typical situations) than making it right, with the result that the implementation is horribly klugy.

      Two examples are the need for a "nexthop" parameter, when the kernel already has this information in its routing tables; and the need to turn off route filtering. Both make it clear that freeswan is not properly integrated (and if you look at the freeswan docs, you'll see that this general problem been on the "to fix" list for a long time).

      • Ummm, not so, I have not ever specified nexthop in any of my configuration. Same with route filtering, I leave it on, without consequence....

        I've seen these complaints about the non-integration of FreeS/WAN before, but usually because people fail to understand the system. They make recommendations so you know exactly what is going on and give the ability to override certain settings just in case, but most of the time the extremely verbose ways of dealing with the parameters as recommended in many howtos is overkill, and could be omitted...
      • You'll be glad to know that the Cerberus/PlutoPlus implementations done by NIST are going to be more widely available in the near future. Specifically, I've been working on extending them to support large-scale configuration management of it. I ported the cerberus (read: ipsec) support to the 2.4 kernel, and am wrapping up the final details at the moment. The good news about it is that it's not done in the hacky way that freeswan did stuff. I'll be creating a sourceforge project for it within the week (I have a deadline to do it by next week), so look for it shortly.

        I actually tried to approach the FreeSWAN folk to considering instrumenting their code with our policy-role-based configuration management support infrastructure, but they said "no US no way" and I didn't really have a choice if I wanted my patches rolled back into the project. The Cerberus and PlutoPlus developers, on the other hand, have been much more polite and helpful.

        I'm sorry. This really doesn't make sense. Just because the kernel is smaller than some other package doesn't mean it can't be bloated. When I download the kernel source, I get sources not only for my build platform but also for a myriad of other architectures that I don't have. This _is_ bloat. It's good that Linux runs on so many architectures, it's good that the kernel has so many featurs, but anyone saying that all this source code they get but never use is bloat is just correct.

        In my opinion, GNOME, X, and KDE come with a lot of bloat that I don't want to cope with. I don't use GNOME or KDE, but I do use X, because I lack a better alternative. The Linux kernel is a fantastic piece of software, exactly because it offers so many features (that many don't need). The source download is pretty huge (and unnecessarily so), but once compiled it's greatly efficient. Any new features is a win, and if you don't want it, you can disable it at configure time.

      Due to kernel modules and the fact that you can "roll your own," the kernel can be as bloated as you want, the only downside is the size of the download. The current installation procedure works well enough for this, though the only feature it really lacks imho is querying dependencies satisfied by an entry.

      Really though, kernels can and will always fit on teeny floppies, providing they're trimmed down enough. Regarding your comment about the end user getting the kitchen sink, have you ever looked at how distros handle this?

      Most make a generic trimmed down kernel cross-compiled for the architecture and build all the modules. It may be the case that the distro copies hoards of modules, but that still isn't going to be as big a package as, say, glibc. If "joe-shmoe" doesn't have Bluetooth or scsi hardware, the corresponding modules won't get loaded, and as a result the bloatedness of the /lib/modules// directory won't bleed into the performance of the actual running kernel.

      One man's bloat is another man's features.

      Hypothetical: I can't believe OpenOffice is so bloated compared to EDLIN from MS-DOS!

      Maybe it's "feature loaded" instead of bloated? While it is true that you can use OpenOffice to duplicate tasks that you might have done in EDLIN, it is capable of so much more.

      There is another kind of bloat which is not caused by features. This kind of bloat does not appear to be present in Linux. The kind of bloat I'm talking about is caused by "optimization". I don't mean optimizing for fast code or small code, but optimizing for "release date". Hey Mr. Customer, would take that new spreadsheet upgrade six months sooner if it required 25% more computing resources to run? All consumers I know would answer Yes. So this is a type of optimization. Optimizing for development time instead of optimizing for computer resources. Given the current low and decreasing cost of computer resources, there is some balance of this that makes sense. Just as once upon a time the "bloat" and value of high level programming languages was hugely debated. Now everyone uses high level languages to optimize for development time. The fact that I could spend six extra months doing it smaller and faster in assembler doesn't matter. Well, today it's the same thing. I don't mean that bad code is written on purpose, just that development time is valued above comptuer resources and machine optimizations, profiling, etc. Again, Linux does not appear to "suffer" from this type of "optimization".

      Another type of bloat is just from plain bad programming. It was not a purposeful decision to optimize development time, it was just the the program is badly written. Linux does not appear to suffer from this kind of bloat either.

    In my experience, Windows 2000's support for IPSec is one reason why it has snared a foothold in many businesses. Having IPSec in mainstream Linux distributions would let us cut Bill off at the pass.

    I hope we're not far from seeing adoption of Linux in places like the financial services industry. If the distributors can make IPSec painless to configure, Linux will make inroads in such industries very quickly.

      In all honesty, Win2k's IPSec impmentation sucks. It dosen't seem to be able to keep track of time... and it forgets esp tunnels like crazy. Linux is already being used quite a bit for the hidden thins in business. The firewalls.. The proxy servers, the VPN Routers. Linux makes a very good box to sit in the corner w/o a monitor, and run a few hundred ipsec tunnels with lets say OSPF [lwolenczak.net] on top of it all.

      Many of the non-us distribuions ship with ipsec, but the big problem is creating some very easy way that can allow elmer fud to create a host to host or a subnet to host or a subnet to subnet ipsec tunnel in under 10 minutes. Preferably 2 minutes.

      What is going to start shifting many businesses to linux is seeing applications such as AutoCAD run on linux. Seeing APIs for controling PLCs on factory floors. If we are able to woo the design and engineering firms to linux.... we will have a powerful foothold on the market.

      Forget the "linux Vs windows" attitude for a moment, and lets just hope that the new linux kernel works nicely with the windows (bad or otherwise) implementation of IPSec for VPN, etc.

      You'll probably snag a lot more users by showing cross-OS compatability as opposed to desktop replacement. As in most cases, it would likely be linux server, windows desktop, with VPN being a nice communication feature in both.I know that I would like my VPN's to work properly between OS's, without the half-baked configurations in FreeSwan.

    What's cool about this is that people are watching kernel development without having to read the lkml or being on irc or whatever. People can now just watch the patches flow into the bk system. I think that's kind of cool. It's like a Kernel News Network.

    Wouldn't this run afoul of many of the U.S. Cryptography export regulations? U.S. DoD prohibits exporting of any product containing mathematically "strong" cryptography (usually, 128-bit) to a lot of places.

    That, and the DMCA which prohibits reversing of any of the encryption that would be found in the new kernel, would create a risk for many of the users downloading the software if they were from anywhere outside the US (and, for US users downloading the software, because it couldn't be explained to them.)

    I'm sure the U.S. government is going to have a lot of fun with this...

    I am not very knowledgeable about security issues, but I am curious if the inclusion of security modules in the kernel will provide for a single point of failure. In other words, as more programs become dependent on the kernel module for security, if an exploit becomes available, will all these dependent programs become exploitable?

    I ask this specifically because of the problem the IE ran into, where it depended on security APIs from Windows, the Windows API had an exploitable bug, and ta-da, IE had an exploitable bug.
