Intel Ethernet and open source have been making history for decades. Doug Boom and Kevin Bross join us for a history lesson and a look toward future innovation. If you drive a car, use a phone, or travel to Mars, chances are you'll encounter foundational ethernet technology Kevin and Doug have helped foster. We take a deep and nerdy dive into the world of open source software and ethernet and learn how it impacts all our lives.

DragonFlyBSD's kernel optimizations pay off, differences between OpenBSD and Linux, NetBSD 2019 Google Summer of Code project list, Reducing that contention, fnaify 1.3 released, vmctl(8): CLI syntax changes, and things that Linux distributions should not do when packaging. Headlines DragonFlyBSD's Kernel Optimizations Are Paying Off (https://www.phoronix.com/scan.php?page=article&item=dragonfly-55-threadripper&num=1) DragonFlyBSD lead developer Matthew Dillon has been working on a big VM rework in the name of performance and other kernel improvements recently. Here is a look at how those DragonFlyBSD 5.5-DEVELOPMENT improvements are paying off compared to DragonFlyBSD 5.4 as well as FreeBSD 12 and five Linux distribution releases. With Dillon using an AMD Ryzen Threadripper system, we used that too for this round of BSD vs. Linux performance benchmarks. The work by Dillon on the VM overhaul and other changes (including more HAMMER2 file-system work) will ultimately culminate with the DragonFlyBSD 5.6 release (well, unless he opts for DragonFlyBSD 6.0 or so). These are benchmarks of the latest DragonFlyBSD 5.5-DEVELOPMENT daily ISO as of this week benchmarked across DragonFlyBSD 5.4.3 stable, FreeBSD 12.0, Ubuntu 19.04, Red Hat Enterprise Linux 8.0, Debian 9.9, Debian Buster, and CentOS 7 1810 as a wide variety of reference points both from newer and older Linux distributions. (As for no Clear Linux reference point for a speedy reference point, it currently has a regression with AMD + Samsung NVMe SSD support on some hardware, including this box, prohibiting the drive from coming up due to a presumed power management issue that is still being resolved.) With Matthew Dillon doing much of his development on an AMD Ryzen Threadripper system after he last year proclaimed the greatness of these AMD HEDT CPUs, for this round of testing I also used a Ryzen Threadripper 2990WX with 32 cores / 64 threads. Tests of other AMD/Intel hardware with DragonFlyBSD will come as the next stable release is near and all of the kernel work has settled down. For now it's mostly entertaining our own curiosity how well these DragonFlyBSD optimizations are paying off and how it's increasing the competition against FreeBSD 12 and Linux distributions. What are the differences between OpenBSD and Linux? (https://cfenollosa.com/blog/what-are-the-differences-between-openbsd-and-linux.html) Maybe you have been reading recently about the release of OpenBSD 6.5 and wonder, "What are the differences between Linux and OpenBSD?" I've also been there at some point in the past and these are my conclusions. They also apply, to some extent, to other BSDs. However, an important disclaimer applies to this article. This list is aimed at people who are used to Linux and are curious about OpenBSD. It is written to highlight the most important changes from their perspective, not the absolute most important changes from a technical standpoint. Please bear with me. A terminal is a terminal is a terminal Practical differences Security and system administration Why philosophical differences matter So what do I choose? How to try OpenBSD *** News Roundup NetBSD 2019 Google Summer of Code (http://blog.netbsd.org/tnf/entry/announcing_google_summer_of_code1) We are very happy to announce The NetBSD Foundation Google Summer of Code 2019 projects: Akul Abhilash Pillai - Adapting TriforceAFL for NetBSD kernel fuzzing Manikishan Ghantasala - Add KNF (NetBSD style) clang-format configuration Siddharth Muralee - Enhancing Syzkaller support for NetBSD Surya P - Implementation of COMPATLINUX and COMPATNETBSD32 DRM ioctls support for NetBSD kernel Jason High - Incorporation of Argon2 Password Hashing Algorithm into NetBSD Saurav Prakash - Porting NetBSD to HummingBoard Pulse Naveen Narayanan - Porting WINE to amd64 architecture on NetBSD The communiting bonding period - where students get in touch with mentors and community - started yesterday.

Reducing that contention (http://www.grenadille.net/post/2019/05/09/Reducing-that-contention) The opening keynote at EuroBSDCon 2016 predicted the future 10 years of BSDs. Amongst all the funny previsions, gnn@FreeBSD said that by 2026 OpenBSD will have its first implementation of SMP. Almost 3 years after this talk, that sounds like a plausible forecast... Why? Where are we? What can we do? Let's dive into the issue! State of affairs Most of OpenBSD's kernel still runs under a single lock, ze KERNEL_LOCK(). That includes most of the syscalls, most of the interrupt handlers and most of the fault handlers. Most of them, not all of them. Meaning we have collected & fixed bugs while setting up infrastructures and examples. Now this lock remains the principal responsible for the spin % you can observe in top(1) and systat(1). I believe that we opted for a difficult hike when we decided to start removing this lock from the bottom. As a result many SCSI & Network interrupt handlers as well as all Audio & USB ones can be executed without big lock. On the other hand very few syscalls are already or almost ready to be unlocked, as we incorrectly say. This explains why basic primitives like tsleep(9), csignal() and selwakeup() are only receiving attention now that the top of the Network Stack is running (mostly) without big lock. Next steps In the past years, most of our efforts have been invested into the Network Stack. As I already mentioned it should be ready to be parallelized. However think we should now concentrate on removing the KERNEL_LOCK(), even if the code paths aren't performance critical. See the Article for the rest of the post fnaify 1.3 released - more games are "fnaify & run" now (https://www.reddit.com/r/openbsd_gaming/comments/btste9/fnaify_13_released_more_games_are_fnaify_run_now/) This release finally addresses some of the problems that prevent simple running of several games. This happens for example when an old FNA.dll library comes with the games that doesn't match the API of our native libraries like SDL2, OpenAL, or MojoShader anymore. Some of those cases can be fixed by simply dropping in a newer FNA.dll. fnaify now asks if FNA 17.12 should be automatically added if a known incompatible FNA version is found. You simply answer yes or no. Another blocker happens when the game expects to check the SteamAPI - either from a running Steam process, or a bundled steam_api library. OpenBSD 6.5-current now has steamworks-nosteam in ports, a stub library for Steamworks.NET that prevents games from crashing simply because an API function isn't found. The repo is here. fnaify now finds this library in /usr/local/share/steamstubs and uses it instead of the bundled (full) Steamworks.NET.dll. This may help with any games that use this layer to interact with the SteamAPI, mostly those that can only be obtained via Steam. vmctl(8): command line syntax changed (https://www.openbsd.org/faq/current.html#r20190529) The order of the arguments in the create, start, and stop commands of vmctl(8) has been changed to match a commonly expected style. Manual usage or scripting with vmctl must be adjusted to use the new syntax. For example, the old syntax looked like this: # vmctl create disk.qcow2 -s 50G The new syntax specifies the command options before the argument: # vmctl create -s 50G disk.qcow2 Something that Linux distributions should not do when packaging things (https://utcc.utoronto.ca/~cks/space/blog/linux/PackageNameClashProblem) Right now I am a bit unhappy at Fedora for a specific packaging situation, so let me tell you a little story of what I, as a system administrator, would really like distributions to not do. For reasons beyond the scope of this blog entry, I run a Prometheus and Grafana setup on both my home and office Fedora Linux machines (among other things, it gives me a place to test out various things involving them). When I set this up, I used the official upstream versions of both, because I needed to match what we are running (or would soon be). Recently, Fedora decided to package Grafana themselves (as a RPM), and they called this RPM package 'grafana'. Since the two different packages are different versions of the same thing as far as package management tools are concerned, Fedora basically took over the 'grafana' package name from Grafana. This caused my systems to offer to upgrade me from the Grafana.com 'grafana-6.1.5-1' package to the Fedora 'grafana-6.1.6-1.fc29' one, which I actually did after taking reasonable steps to make sure that the Fedora version of 6.1.6 was compatible with the file layouts and so on from the Grafana version of 6.1.5. Why is this a problem? It's simple. If you're going to take over a package name from the upstream, you should keep up with the upstream releases. If you take over a package name and don't keep up to date or keep up to date only sporadically, you cause all sorts of heartburn for system administrators who use the package. The least annoying future of this situation is that Fedora has abandoned Grafana at 6.1.6 and I am going to 'upgrade' it with the upstream 6.2.1, which will hopefully be a transparent replacement and not blow up in my face. The most annoying future is that Fedora and Grafana keep ping-ponging versions back and forth, which will make 'dnf upgrade' into a minefield (because it will frequently try to give me a 'grafana' upgrade that I don't want and that would be dangerous to accept). And of course this situation turns Fedora version upgrades into their own minefield, since now I risk an upgrade to Fedora 30 actually reverting the 'grafana' package version on me.

Strategic thinking to keep FreeBSD relevant, reflecting on the soul of a new machine, 10GbE Benchmarks On Nine Linux Distros and FreeBSD, NetBSD integrating LLVM sanitizers in base, FreeNAS 11.2 distrowatch review, and more. ##Headlines ###Strategic thinking, or what I think what we need to do to keep FreeBSD relevant Since I participate in the FreeBSD project there are from time to time some voices which say FreeBSD is dead, Linux is the way to go. Most of the time those voices are trolls, or people which do not really know what FreeBSD has to offer. Sometimes those voices wear blinders, they only see their own little world (were Linux just works fine) and do not see the big picture (like e.g. competition stimulates business, …) or even dare to look what FreeBSD has to offer. Sometimes those voices raise a valid concern, and it is up to the FreeBSD project to filter out what would be beneficial. Recently there were some mails on the FreeBSD lists in the sense of “What about going into direction X?”. Some people just had the opinion that we should stay where we are. In my opinion this is similarly bad to blindly saying FreeBSD is dead and following the masses. It would mean stagnation. We should not hold people back in exploring new / different directions. Someone wants to write a kernel module in (a subset of) C++ or in Rust… well, go ahead, give it a try, we can put it into the Ports Collection and let people get experience with it. This discussion on the mailinglists also triggered some kind of “where do we see us in the next years” / strategic thinking reflection. What I present here, is my very own opinion about things we in the FreeBSD project should look at, to stay relevant in the long term. To be able to put that into scope, I need to clarify what “relevant” means in this case. FreeBSD is currently used by companies like Netflix, NetApp, Cisco, Juniper, and many others as a base for products or services. It is also used by end‐users as a work‐horse (e.g. mailservers, webservers, …). Staying relevant means in this context, to provide something which the user base is interested in to use and which makes it more easy / fast for the user base to deliver whatever they want or need to deliver than with another kind of system. And this in terms of time to market of a solution (time to deliver a service like a web‐/mail‐/whatever‐server or product), and in terms of performance (which not only means speed, but also security and reliability and …) of the solution. I have categorized the list of items I think are important into (new) code/features, docs, polishing and project infrastructure. Links in the following usually point to documentation/HOWTOs/experiences for/with FreeBSD, and not to the canonical entry points of the projects or technologies. In a few cases the links point to an explanation in the wikipedia or to the website of the topic in question. ###Reflecting on The Soul of a New Machine Long ago as an undergraduate, I found myself back home on a break from school, bored and with eyes wandering idly across a family bookshelf. At school, I had started to find a calling in computing systems, and now in the den, an old book suddenly caught my eye: Tracy Kidder’s The Soul of a New Machine. Taking it off the shelf, the book grabbed me from its first descriptions of Tom West, captivating me with the epic tale of the development of the Eagle at Data General. I — like so many before and after me — found the book to be life changing: by telling the stories of the people behind the machine, the book showed the creative passion among engineers that might otherwise appear anodyne, inspiring me to chart a course that might one day allow me to make a similar mark. Since reading it over two decades ago, I have recommended The Soul of a Machine at essentially every opportunity, believing that it is a part of computing’s literary foundation — that it should be considered our Odyssey. Recently, I suggested it as beach reading to Jess Frazelle, and apparently with perfect timing: when I saw the book at the top of her vacation pile, I knew a fuse had been lit. I was delighted (though not at all surprised) to see Jess livetweet her admiration of the book, starting with the compelling prose, the lucid technical explanations and the visceral anecdotes — but then moving on to the deeper technical inspiration she found in the book. And as she reached the book’s crescendo, Jess felt its full power, causing her to reflect on the nature of engineering motivation. Excited to see the effect of the book on Jess, I experienced a kind of reflected recommendation: I was inspired to (re-)read my own recommendation! Shortly after I started reading, I began to realize that (contrary to what I had been telling myself over the years!) I had not re-read the book in full since that first reading so many years ago. Rather, over the years I had merely revisited those sections that I remembered fondly. On the one hand, these sections are singular: the saga of engineers debugging a nasty I-cache data corruption issue; the young engineer who implements the simulator in an impossibly short amount of time because no one wanted to tell him that he was being impossibly ambitious; the engineer who, frustrated with a nanosecond-scale timing problem in the ALU that he designed, moved to a commune in Vermont, claiming a desire to deal with “no unit of time shorter than a season”. But by limiting myself to these passages, I was succumbing to the selection bias of my much younger self; re-reading the book now from start to finish has given new parts depth and meaning. Aspects that were more abstract to me as an undergraduate — from the organizational rivalries and absurdities of the industry to the complexities of West’s character and the tribulations of the team down the stretch — are now deeply evocative of concrete episodes of my own career. See Article for rest… ##News Roundup ###Out-Of-The-Box 10GbE Network Benchmarks On Nine Linux Distributions Plus FreeBSD 12 Last week I started running some fresh 10GbE Linux networking performance benchmarks across a few different Linux distributions. That testing has now been extended to cover nine Linux distributions plus FreeBSD 12.0 to compare the out-of-the-box networking performance. Tested this round alongside FreeBSD 12.0 was Antergos 19.1, CentOS 7, Clear Linux, Debian 9.6, Fedora Server 29, openSUSE Leap 15.0, openSUSE Tumbleweed, Ubuntu 18.04.1 LTS, and Ubuntu 18.10. All of the tests were done with a Tyan S7106 1U server featuring two Intel Xeon Gold 6138 CPUs, 96GB of DDR4 system memory, and Samsung 970 EVO SSD. For the 10GbE connectivity on this server was an add-in HP NC523SFP PCIe adapter providing two 10Gb SPF+ ports using a QLogic 8214 controller. Originally the plan as well was to include Windows Server 2016/2019. Unfortunately the QLogic driver download site was malfunctioning since Cavium’s acquisition of the company and the other Windows Server 2016 driver options not panning out and there not being a Windows Server 2019 option. So sadly that Windows testing was thwarted so I since started testing over with a Mellanox Connectx-2 10GbE NIC, which is well supported on Windows Server and so that testing is ongoing for the next article of Windows vs. Linux 10 Gigabit network performance plus some “tuned” Linux networking results too. ###Integration of the LLVM sanitizers with the NetBSD base system Over the past month I’ve merged the LLVM compiler-rt sanitizers (LLVM svn r350590) with the base system. I’ve also managed to get a functional set of Makefile rules to build all of them, namely: ASan, UBSan, TSan, MSan, libFuzzer, SafeStack, XRay. In all supported variations and modes that are supported by the original LLVM compiler-rt package. ###Distrowatch FreeNAS 11.2 review The project’s latest release is FreeNAS 11.2 and, at first, I nearly overlooked the new version because it appeared to be a minor point release. However, a lot of work went into the new version and 11.2 offers a lot of changes when compared next to 11.1, “including a major revamp of the web interface, support for self-encrypting drives, and new, backwards-compatible REST and WebSocket APIs. This update also introduces iocage for improved plugins and jails management and simplified plugin development.” ##Beastie Bits Instructions for installing rEFInd to dual boot a computer with FreeBSD and windows (and possibly other OSes as well).

SCP client vulnerabilities, BSDs vs Linux benchmarks on a Tyan EPYC Server, fame for the Unix inventors, Die IPv4, GhostBSD 18.12 released, Unix in pictures, and more. ##Headlines ###scp client multiple vulnerabilities Overview SCP clients from multiple vendors are susceptible to a malicious scp server performing unauthorized changes to target directory and/or client output manipulation. Description Many scp clients fail to verify if the objects returned by the scp server match those it asked for. This issue dates back to 1983 and rcp, on which scp is based. A separate flaw in the client allows the target directory attributes to be changed arbitrarily. Finally, two vulnerabilities in clients may allow server to spoof the client output. Impact Malicious scp server can write arbitrary files to scp target directory, change the target directory permissions and to spoof the client output. Details The discovered vulnerabilities, described in more detail below, enables the attack described here in brief. The attacker controlled server or Man-in-the-Middle(*) attack drops .bash_aliases file to victim’s home directory when the victim performs scp operation from the server. The transfer of extra files is hidden by sending ANSI control sequences via stderr. For example: user@local:~$ scp user@remote:readme.txt . readme.txt 100% 494 1.6KB/s 00:00 user@local:~$ Once the victim launches a new shell, the malicious commands in .bash_aliases get executed. *) Man-in-the-Middle attack does require the victim to accept the wrong host fingerprint. ###FreeBSD 12.0 vs. DragonFlyBSD 5.4 vs. TrueOS 18.12 vs. Linux On A Tyan EPYC Server Last month when running FreeBSD 12.0 benchmarks on a 2P EPYC server I wasn’t able to run any side-by-side benchmarks with the new DragonFlyBSD 5.4 as this BSD was crashing during the boot process on that board. But fortunately on another AMD EPYC server available, the EPYC 1P TYAN Transport SX TN70A-B8026, DragonFlyBSD 5.4.1 runs fine. So for this first round of BSD benchmarking in 2019 are tests of FreeBSD 11.2, FreeBSD 12.0, DragonFlyBSD 5.4.1, the new TrueOS 18.12, and a few Linux distributions (CentOS 7, Ubuntu 18.04.1 LTS, and Clear Linux) on this EPYC 7601 server in a variety of workloads. DragonFlyBSD 5.4.1 ran fine on this Tyan server and could boot fine unlike the issue encountered on the Dell PowerEdge R7425 for this particular BSD. But on the Tyan server, DragonFlyBSD 5.2.2 wouldn’t boot so only this latest DragonFlyBSD release series was used as part of the comparison. A summary of the operating systems tested for this EPYC 7601 OS benchmark comparison included: DragonFlyBSD 5.4.1 - The latest release of Matthew Dillon’s operating system while using the HAMMER2 file-system and GCC 8.1 compiler that is now the default system compiler for this BSD. FreeBSD 11.2 - The previous stable release of FreeBSD. Installed with a ZFS file-system. FreeBSD 12.0 - The latest stable release of FreeBSD and installed with its ZFS option. TrueOS 18.12 - The latest release of the iX systems’ FreeBSD derivative. TrueOS 18.12 is based on FreeBSD 13.0-CURRENT and uses ZFS by default and was using the Clang 7.0.1 compiler compared to Clang 6.0.1 on FreeBSD 12.0. CentOS Linux 7 - The latest EL7 operating system performance. Ubuntu 18.04.1 LTS - The latest Ubuntu Long Term Support release. Clear Linux 27120 - The latest rolling release as of testing out of Intel’s Open-Source Technology Center. Clear Linux often reflects as close to the gold standard for performance as possible with its insanely tuned software stack for offering optimal performance on x86_64 performance for generally showing best what the hardware is capable of. Throughout all of this testing, the Tyan 2U server was kept to its same configuration of an AMD EPYC 7601 (32 cores / 64 threads) at stock speeds, 8 x 16GB DDR4-2666 ECC memory, and 280GB Intel Optane 900p SSD benchmarks. ##News Roundup National Inventors Hall of Fame honors creators of Unix Dennis Ritchie (Posthumous) and Ken Thompson: UNIX Operating System Thompson and Ritchie’s creation of the UNIX operating system and the C programming language were pivotal developments in the progress of computer science. Today, 50 years after its beginnings, UNIX and UNIX-like systems continue to run machinery from supercomputers to smartphones. The UNIX operating system remains the basis of much of the world’s computing infrastructure, and C language – written to simplify the development of UNIX – is one of the most widely used languages today. ###Die IPV4, Die Imagine, it is 2019. Easy, ha? Imagine, it is 2019 and you want to turn off IPv4. Like, off off. Really off. Not disabling IPv6, but disabling IPv4. Two steps back You might be coming here wondering, why would anybody want to do what we are asking to be done. Well, it is dead simple: We are running data centers (like Data Center Light) with a lot of IPv6 only equipment. There simply is no need for IPv4. So why would we want to have it enabled? Also, here at ungleich, we defined 2019 as the year to move away from IPv4. The challenge Do you like puzzles? Competitions? Challenges? Hacking? Well. If ANY of this is of your interest, here is a real challenge for you: We offer a 100 CHF (roughly 100 USD) for anyone who can give us a detailed description of how to turn IPv4 completely off in an operating system and allowing it to communicate with IPv6 only. This should obviously include a tiny proof that your operating system is really unable to use IPv4 at all. Just flushing IPv4 addresses and keeping the IPv4 stack loaded, does not count. ###GhostBSD 18.12 released GhostBSD 18.12 is an updated iso of GhostBSD 18.10 with some little changes to the live DVD/USB and with updated packages. What has changed since 18.10 removed default call of kernel modules for AMD and Intel replaced octopkg by software-station added back gop hacks to the live system added ghostbsd-drivers and ghostbsd-utils we updated the packages to the latest build ###And Now for a laugh : #unixinpictures ##Beastie Bits We are now closer to the Y2038 bug than the Y2K bug OpenBSD Enterprise use AT&T Unix Books Process title and missing memory space The History of a Security Hole unbound-adblock: The ultimate network adblocker!

A EULA in FOSS clothing, NetBSD with more LLVM support, Thoughts on FreeBSD 12.0, FreeBSD Performance against Windows and Linux on Xeon, Microsoft shipping NetBSD, and more. Headlines A EULA in FOSS clothing? There was a tremendous amount of reaction to and discussion about my blog entry on the midlife crisis in open source. As part of this discussion on HN, Jay Kreps of Confluent took the time to write a detailed response — which he shortly thereafter elevated into a blog entry. Let me be clear that I hold Jay in high regard, as both a software engineer and an entrepreneur — and I appreciate the time he took to write a thoughtful response. That said, there are aspects of his response that I found troubling enough to closely re-read the Confluent Community License — and that in turn has led me to a deeply disturbing realization about what is potentially going on here. To GitHub: Assuming that this is in fact a EULA, I think it is perilous to allow EULAs to sit in public repositories. It’s one thing to have one click through to accept a license (though again, that itself is dubious), but to say that a git clone is an implicit acceptance of a contract that happens to be sitting somewhere in the repository beggars belief. With efforts like choosealicense.com, GitHub has been a model in guiding projects with respect to licensing; it would be helpful for GitHub’s counsel to weigh in on their view of this new strain of source-available proprietary software and the degree to which it comes into conflict with GitHub’s own terms of service. To foundations concerned with software liberties, including the Apache Foundation, the Linux Foundation, the Free Software Foundation, the Electronic Frontier Foundation, the Open Source Initiative, and the Software Freedom Conservancy: the open source community needs your legal review on this! I don’t think I’m being too alarmist when I say that this is potentially a dangerous new precedent being set; it would be very helpful to have your lawyers offer their perspectives on this, even if they disagree with one another. We seem to be in some terrible new era of frankenlicenses, where the worst of proprietary licenses are bolted on to the goodwill created by open source licenses; we need your legal voices before these creatures destroy the village! NetBSD and LLVM NetBSD entering 2019 with more complete LLVM support I’m recently helping the NetBSD developers to improve the support for this operating system in various LLVM components. As you can read in my previous report, I’ve been focusing on fixing build and test failures for the purpose of improving the buildbot coverage. Previously, I’ve resolved test failures in LLVM, Clang, LLD, libunwind, openmp and partially libc++. During the remainder of the month, I’ve been working on the remaining libc++ test failures, improving the NetBSD clang driver and helping Kamil Rytarowski with compiler-rt. The process of upstreaming support to LLVM sanitizers has been finalized I’ve finished the process of upstreaming patches to LLVM sanitizers (almost 2000LOC of local code) and submitted to upstream new improvements for the NetBSD support. Today out of the box (in unpatched version) we have support for a variety of compiler-rt LLVM features: ASan (finds unauthorized memory access), UBSan (finds unspecified code semantics), TSan (finds threading bugs), MSan (finds uninitialized memory use), SafeStack (double stack hardening), Profile (code coverage), XRay (dynamic code tracing); while other ones such as Scudo (hardened allocator) or DFSan (generic data flow sanitizer) are not far away from completeness. The NetBSD support is no longer visibly lacking behind Linux in sanitizers, although there are still failing tests on NetBSD that are not observed on Linux. On the other hand there are features working on NetBSD that are not functional on Linux, like sanitizing programs during early initialization process of OS (this is caused by /proc dependency on Linux that is mounted by startup programs, while NetBSD relies on sysctl(3) interfaces that is always available). News Roundup Thoughts on FreeBSD 12.0 Playing with FreeBSD with past week I don’t feel as though there were any big surprises or changes in this release compared to FreeBSD 11. In typical FreeBSD fashion, progress tends to be evolutionary rather than revolutionary, and this release feels like a polished and improved incremental step forward. I like that the installer handles both UFS and ZFS guided partitioning now and in a friendly manner. In the past I had trouble getting FreeBSD’s boot menu to work with boot environments, but that has been fixed for this release. I like the security options in the installer too. These are not new, but I think worth mentioning. FreeBSD, unlike most Linux distributions, offers several low-level security options (like hiding other users’ processes and randomizing PIDs) and I like having these presented at install time. It’s harder for people to attack what they cannot see, or predict, and FreeBSD optionally makes these little adjustment for us. Something which stands out about FreeBSD, compared to most Linux distributions I run, is that FreeBSD rarely holds the user’s hand, but also rarely surprises the user. This means there is more reading to do up front and new users may struggle to get used to editing configuration files in a text editor. But FreeBSD rarely does anything unless told to do it. Updates rarely change the system’s behaviour, working technology rarely gets swapped out for something new, the system and its applications never crashed during my trial. Everything was rock solid. The operating system may seem like a minimal, blank slate to new users, but it’s wonderfully dependable and predictable in my experience. I probably wouldn’t recommend FreeBSD for desktop use. It’s close relative, GhostBSD, ships with a friendly desktop and does special work to make end user applications run smoothly. But for people who want to run servers, possible for years without change or issues, FreeBSD is a great option. It’s also an attractive choice, in my opinion, for people who like to build their system from the ground up, like you would with Debian’s server install or Arch Linux. Apart from the base tools and documentation, there is nothing on a FreeBSD system apart from what we put on it. FreeBSD 12.0 Performance Against Windows & Linux On An Intel Xeon Server Last week I posted benchmarks of Windows Server 2019 against various Linux distributions using a Tyan dual socket Intel Xeon server. In this article are some complementary results when adding in the performance of FreeBSD 11.2 against the new FreeBSD 12.0 stable release for this leading BSD operating system. As some fun benchmarks to end out 2018, here are the results of FreeBSD 11.2/12.0 (including an additional run when using GCC rather than Clang) up against Windows Server and several enterprise-ready Linux distributions. While FreeBSD 12.0 had picked up just one win of the Windows/Linux comparisons run, the FreeBSD performance is moving in the right direction. FreeBSD 12.0 was certainly faster than FreeBSD 11.2 on this dual Intel Xeon Scalable server based on a Tyan 1U platform. Meanwhile, to no surprise given the data last week, Clear Linux was by far the fastest out-of-the-box operating system tested. I did run some extra benchmarks on FreeBSD 11.2/12.0 with this hardware: in total I ran 120 benchmarks for these BSD tests. Of the 120 tests, there were just 15 cases where FreeBSD 11.2 was faster than 12.0. Seeing FreeBSD 12.0 faster than 11.2 nearly 90% of the time is an accomplishment and usually with other operating systems we see more of a mixed bag on new releases with not such solidly better performance. It was also great seeing the competitive performance out of FreeBSD when using the Clang compiler for the source-based tests compared to the GCC8 performance. Additional data available via this OpenBenchmarking.org result file. How NetBSD came to be shipped by Microsoft Google cache in case the site is down In 2000, Joe Britt, Matt Hershenson and Andy Rubin formed Danger Incorporated. Danger developed the world’s first recognizable smartphone, the Danger HipTop. T-Mobile sold the first HipTop under the brand name Sidekick in October of 2002. Danger had a well developed kernel that had been designed and built in house. The kernel came to be viewed as not a core intellectual property and Danger started a search for a replacement. For business reasons, mostly to do with legal concerns over the Gnu Public License, Danger rejected Linux and began to consider BSD Unix as a replacement for the kernel. In 2006 I was hired by Mike Chen, the manager of the kernel development group to investigate the feasibility of replacing the Danger kernel with a BSD kernel, to select the version of BSD to use, to develop a prototype and to develop the plan for adapting BSD to Danger’s requirements. NetBSD was easily the best choice among the BSD variations at the time because it had well developed cross development tools. It was easy to use a NetBSD desktop running an Intel release to cross compile a NetBSD kernel and runtime for a device running an ARM processor. (Those interested in mailing list archaeology might be amused to investigate NetBSD technical mailing list for mail from picovex, particularly from Bucky Katz at picovex.) We began product development on the specific prototype of the phone that would become the Sidekick LX2009 in 2007 and contracts for the phone were written with T-Mobile. We were about half way through the two year development cycle when Microsoft purchased Danger in 2008. Microsoft would have preferred to ship the Sidekick running Windows/CE rather than NetBSD, but a schedule analysis performed by me, and another by an independent outside contractor, indicated that doing so would result in unacceptable delay.

This week on the show, we will be talking to FreeBSD developer and former core-team member John Baldwin about a variety of topics, including running a DevSummit, everything you needed or wanted to know. Coming up right now on BSDNow, the place to B...SD. This episode was brought to you by Headlines FreeBSD server retired after almost 19 years (http://www.theregister.co.uk/2016/01/14/server_retired_after_18_years_and_ten_months_beat_that_readers/) We've heard stories about this kind of thing before, that box that often sits under-appreciated, but refuses to die. Well the UK register has picked up on a story of a FreeBSD server finally being retired after almost 19 years of dedicated service. “In its day, it was a reasonable machine - 200MHz Pentium, 32MB RAM, 4GB SCSI-2 drive,” Ross writes. “And up until recently, it was doing its job fine.” Of late, however the “hard drive finally started throwing errors, it was time to retire it before it gave up the ghost!” The drive's a Seagate, for those of you looking to avoid drives that can't deliver more than 19 years of error-free operations. This system in particular had been running FreeBSD 2.2.1 over the years. Why not upgrade you ask? Ross has an answer for that: “It was heavily firewalled and only very specific services were visible to anyone, and most only visible to our directly connected customers,” Ross told Vulture South. “By the time it was probably due for a review, things had moved so far that all the original code was so tightly bound to the operating system itself, that later versions of the OS would have (and ultimately, did) require substantial rework. While it was running and not showing any signs of stress, it was simply expedient to leave sleeping dogs lie.” All in all, an amazing story of the longevity of a system and its operating system. Do you have a server with a similar or even greater uptime? Let us know so we can try and top this story. *** Roundup of all the BSDs (https://www.linuxvoice.com/group-test-bsd-distros/) The magazine LinuxVoice recently did a group test of a variety of “BSD Distros”. Included in their review were Free/Open/Net/Dragon/Ghost/PC It starts with a pretty good overview of BSD in general, its starts and the various projects / forks that spawned from it, such as FreeNAS / Junos / Playstation / PFSense / etc The review starts with a look at OpenBSD, and the consensus reached is that it is good, but does require a bit more manual work to run as a desktop. (Most of the review focuses on desktop usage). It ends up with a solid ⅘ stars though. Next it moves into GhostBSD, discusses it being a “Live” distro, which can optionally be installed to disk. It loses a few points for lacking a graphical package management utility, and some bugs during the installation, but still earns a respectable ⅗ stars. Dragonfly gets the next spin and gets praise for its very-up to date video driver support and availability of the HAMMER filesystem. It also lands at ⅗ stars, partly due to the reviewer having to use the command-line for management. (Notice a trend here?) NetBSD is up next, and gets special mention for being one of the only “distros” that doesn't do frequent releases. However that doesn't mean you can't have updated packages, since the review mentions pkgsrc and pkg as both available to customize your desktop. The reviewer was slightly haunted by having to edit files in /etc by hand to do wireless, but still gives NetBSD a ⅗ overall. Last up are FreeBSD and PC-BSD, which get a different sort of head-to-head review. FreeBSD goes first, with mention that the text-install is fairly straight-forward and most configuration will require being done by hand. However the reviewer must be getting use to the command-line at this point, because he mentions: “This might sound cumbersome, but is actually pretty straightforward and at the end produces a finely tuned aerodynamic system that does exactly what you want it to do and nothing else.” He does mention that FreeBSD is the ultimate DIY system, even to the point of not having the package management tools provided out of box. PC-BSD ultimately gets a lot of love in this review, again with it being focused on desktop usage this follows. Particularly popular are all the various tools written to make PC-BSD easier to use, such as Life-Preserver, Warden, the graphical installer and more. (slight mistake though, Life-Preserver does not use rsync to backup to FreeNAS, it does ZFS replication) In the end he rates FreeBSD ⅘ and PC-BSD a whopping 5/5 for this roundup. While reviews may be subjective to the particular use-case being evaluated for, it is still nice to see BSD getting some press and more interest from the Linux community in general. *** OpenBSD Laptops (http://www.tedunangst.com/flak/post/openbsd-laptops) Our buddy Ted Unangst has posted a nice “planning ahead” guide for those thinking of new laptops for 2016 and the upcoming OpenBSD 5.9 He starts by giving us a status update on several of the key driver components that will be in 5.9 release“5.9 will be the first release to support the graphics on Broadwell CPUs. This is anything that looks like i5-5xxx. There are a few minor quirks, but generally it works well. There's no support for the new Skylake models, however. They'll probably work with the VESA driver but minus suspend/resume/acceleration (just as 5.8 did with Broadwell).” He then goes on to mention that the IWM driver works well with most of the revisions (7260, 7265, and 3160) that ship with broadwell based laptops, however the newer skylake series ships with the 8260, which is NOT yet supported. He then goes on to list some of the more common makes and models to look for, starting with the broadwell based X1 carbons which work really well (Kris gives +++), but make sure its not the newer skylake model just yet. The macbook gets a mention, but probably should be avoided due to broadcom wifi The Dell XPS he mentions as a good choice for a powerful (portable) desktops *** Significant changes from NetBSD 7.0 to 8.0 (https://www.netbsd.org/changes/changes-8.0.html) Updated to GCC 4.8.5 Imported dhcpcd and replaced rtsol and rtsold gpt(8) utility gained the ability to resize partitions and disks, as well as change the type of a partition OpenSSH 7.1 and OpenSSL 1.0.1q FTP client got support for SNI for https Imported dtrace from FreeBSD Add syscall support Add lockstat support *** Interview - John Baldwin - jhb@freebsd.org (mailto:jhb@freebsd.org) / @BSDHokie (https://twitter.com/BSDHokie) FreeBSD Kernel Debugging News Roundup Dragonfly Mail Agent spreads to FreeBSD and NetBSD (https://www.dragonflydigest.com/2016/01/18/17508.html) DMA, the Dragonfly Mail Agent is now available not only in Dragonfly's dports, but also FreeBSD ports, and NetBSD pkgsrc “dma is a small Mail Transport Agent (MTA), designed for home and office use. It accepts mails from locally installed Mail User Agents (MUA) and delivers the mails either locally or to a remote destination. Remote delivery includes several features like TLS/SSL support and SMTP authentication. dma is not intended as a replacement for real, big MTAs like sendmail(8) or postfix(1). Consequently, dma does not listen on port 25 for incoming connections.” There was a project looking at importing DMA into the FreeBSD base system to replace sendmail, I wonder of the port signals that some of the blockers have been fixed *** ZFS UEFI Support has landed! (https://svnweb.freebsd.org/base?view=revision&revision=294068) Originally started by Eric McCorkle Picked up by Steven Hartland Including modularizing the existing UFS boot code, and adding ZFS boot code General improvements to the EFI loader including using more of libstand instead of containing its own implementations of many common functions Thanks to work by Toomas Soome, there is now a Beastie Menu as part of the EFI loader, similar to the regular loader As soon as this was committed, I added a few lines to it to connect the ZFS BE Menu to it, thanks to all of the above, without whom my work wouldn't be usable It should be relatively easy to hook my GELI boot stuff in as a module, and possibly just stack the UFS and ZFS modules on top of it I might try to redesign the non-EFI boot code to use a similar design instead of what I have now *** How three BSD OSes compare to ten Linux Distros (http://www.phoronix.com/scan.php?page=article&item=3bsd-10linux) After benchmarking 10 of the latest Linux distros, Phoronix took to benchmarking 3 of the big BSDs DragonFlyBSD 4.4.1 - The latest DragonFly release with GCC 5.2.1 and the HAMMER file-system. OpenBSD 5.8 - OpenBSD 5.8 with GCC 4.2.1 as the default compiler and FFS file-system. PC-BSD 10.2 - Derived off FreeBSD 10.2, the defaults were the Clang 3.4.1 compiler and ZFS file-system. In the SQLite test, PCBSD+ZFS won out over all of the Linux distros, including those that were also using ZFS In the first compile benchmark, PCBSD came second only to Intel's Linux distro, Clear Linux. OpenBSD can last, although it is not clear if the benchmark was just comparing the system compiler, which would be unfair to OpenBSD In Disk transaction performance, against ZFS won the day, with PCBSD edging out the Linux distros. OpenBSD's older ffs was hurt by the lack of soft updates, and DragonFly's Hammer did not perform well. Although in an fsync() heavy test, safety is more important that speed As with all benchmarks, these obviously need to be taken with a grain of salt In some of them you can clearly see that the ‘winner' has a much higher standard error, suggesting that the numbers are quite variable *** OPNSense 15.7.24 Released (https://opnsense.org/opnsense-15-7-24-released/) We are just barely into the new year and OPNSense has dropped a new release on us to play with. This new version, 15.7.24 brings a bunch of notable changes, which includes improvements to the firewall UI and a plugin management section of the firmware page. Additionally better signature verification using PKG's internal verification mechanisms was added for kernel and world updates. The announcement contains the full rundown of changes, including the suricata, openvpn and ntp got package bumps as well. *** Beastie Bits A FreeBSD 10 Desktop How-to (https://cooltrainer.org/a-freebsd-desktop-howto/) (A bit old, but still one of the most complete walkthroughs of a desktop FreeBSD setup from scratch) BSD and Scale 14 (http://fossforce.com/2016/01/bsd-ready-scale-14x/) Xen support enabled in OpenBSD -current (http://undeadly.org/cgi?action=article&sid=20160114113445&mode=expanded) Feedback/Questions Matt - Zil Sizes (http://slexy.org/view/s20a0mLaAv) Drin - IPSEC (http://slexy.org/view/s21qpiTF8h) John - ZFS + UEFI (http://slexy.org/view/s2HCq0r0aD) Jake - ZFS Cluster SAN (http://slexy.org/view/s2VORfyqlS) Phillip - Media Server (http://slexy.org/view/s20ycRhUkM) ***
