An anonymous reader writes "FreeBSD 10.0 has been released. A few highlights include: pkg is now the default package management utility. Major enhancements in virtualization, including the addition of bhyve, virtio, and native paravirtualized drivers providing support for FreeBSD as a guest operating system on Microsoft Hyper-V. Support for the high-performance LZ4 compression algorithm has been added to ZFS and TRIM support for SSD has been added to ZFS. clang is the default compiler. This release has official Raspberry Pi support. For a complete list of new features and known problems, please see the online release notes and a quick FreeBSD installation video is here. FreeBSD 10.0-RELEASE may be downloaded via ftp or via a torrent client that supports web seeding."

    Good to hear. I'm sure I'm not the only one who really likes the BSDs in general. After almost 20 years in the IT biz, I would still choose FreeBSD or OpenBSD for my server needs for almost anything over almost anything. I've never been disappointed in the service of either BSD variant. Kudos to the FreeBSD devs!

    OpenBSD does have cleaner code because they continually audit their code. It's the only way. OpenBSD also does not allow binary blobs, which in today's world would be the height if stupidity because you cannot validate what is in them, view their source, to whom they may communicate with unbeknownst to you. Clean, open source viewable code is a must to establish and maintain trust. Binary blobs and the recent Linux model of cooperating with the MS secure boot initiative scares the crap out of many, including myself. I will likely be buying the same machines that RMS uses from this point forward.

    But if nobody runs it, you do not uncover bugs and you never get a .1 release.

    Yeah, we're talking the NIMFY effect: not in my front yard.

    Really, with the .0 releases, if you try to stay fairly mainstream in your deployment, and you're mindfull about the necessary mitigations if it doesn't go well, the risk is not outrageous. But first test your backups.

    If I had to choose between 10.0 (which I hardly know) and 5.3 (all too well known) I'd pick 10.0 in a heartbeat. That series should have started out at 5.-5 (five dot negative five).

    The .0 thing is just a loose heuristic.

    Do you really need VMWare tools?

    Yes.

    Things like Gui integrations are fine and handy/essential if you are virtualizing a desktop OS.

    But even if setting up a headless virtual server that you never access on the console after sshd is running you should still use them in order to benefit from virtualized disk and network I/O. This can deliver decent speedups if your VM is bottlenecking in that area.

    The drivers you want should be in ports, or a precompiled package for all common OS's. If this is not true for your VM system then you should be questioning the VM provider, not the guest OS, about why they are so hard to setup.

    My primary attraction is the strengthened random number generation for cryptography. This eliminates the NSA introduced weaknesses in the underlying hardware.

    That alone is enough to turn me into a rapid FreeBSD supporter.

    Capsicum, POSIX and NFS4 ACLs are all about adding complexity to allow for greater administrative policy enforcement

    This is almost true for ACLs. ACLs are no more expressive than standard UNIX permissions, but they are significantly simpler for implementing the same thing - you no longer need to create a group for every set of people who want to share things. This lets you leave your default at share-nothing, and explicitly share the things that you need to share with the people that you need to share it with. The code for implementing them is significantly less complex than the work arounds that you need for their absence if you want the same level of access control, and if you don't want the same level of access control it's because you're fine with leaving things more widely readable than they need to be. Neither of these attitudes is good for security.

    Capsicum is definitely not about adding complexity. The implementation adds an extra bitmask check on file accesses and restricts system calls to a whitelisted set. The total code changes in the kernel are very small and easy to audit (and have been audited by several groups). The code changes in userspace code are far more significant. The sandboxing in Chromium, for example, is six times more lines of code on OpenBSD using chroot() than it is on FreeBSD using Capsicum, and offers less isolation (for example, the renderer processes on OpenBSD can create network sockets, so an image in an email that exploits libpng or libjpeg vulnerabilities can phone home and send copies of all of your emails if you use webmail from OpenBSD, with Capsicum is can't). The privilege separation code in OpenSSH is also cleaner and easier to audit when it uses Capsicum.

    In OpenBSD, security means that you eliminate bugs so that the most basic promise is held true.

    In FreeBSD, we care about mitigation. Useful software is never bug free, no matter how simple you make it. The goal is to ensure that once an attacker finds a bug, they can't use it to exploit the system. That doesn't mean 'they can't get root', because on a huge number of modern systems, from single-user laptops to single-service VMs, getting ambient authority for a single user can mean the same as getting root, when it comes to having access to the data that the user cares about. Jails, Capsicum, and so on are all about enforcing the principle of least privilege, so when a bug is discovered the attacker only gets control of a sandbox with no access to the rest of the user's data. This used to be something that OpenBSD people cared about.

Science is to computer science as hydrodynamics is to plumbing.
