Technically, the 6.13 release is not until this Sunday, and I'm recording this before Sunday, so we're just going to roll the dice, and hopefully it doesn't get delayed. Also, we have some distro news this week to talk about with a new release from Linux Mint, MX Linux, and OpenSUSE. We also have some security news related to the rsync project, as well as a big flaw that was found in the Linux kernel. We're gonna talk about all of this and so much more on This Week in Linux, your weekly news show that keeps you up to date with what's going on in the Linux and Open Source world.

Sometimes running the latest and greatest means you have to pave your own path. This week two examples from living on the edge.

Are the free software alternatives good enough? The conclusion to our 60-day challenge to drop Google, Apple, and the iPhone.

Today we are finally taking on a project months in the making, and we're switching to an entirely new generation of Linux tech in the process.

Project Trident 18.12 released, Spotifyd on NetBSD, OPNsense 18.7.10 is available, Ultra EPYC AMD Powered Sun Ultra 24 Workstation, OpenRsync, LLD porting to NetBSD, and more. ##Headlines ###AsiaBSDCon 2019 Call for Papers You have until Jan 30th to submit Full paper requirement is relaxed a bit this year (this year ONLY!) due to the short submission window. You don’t need all 10-12 pages, but it is still preferred. Send a message to secretary@asiabsdcon.org with your proposal. Could be either for a talk or a tutorial. Two days of tutorials/devsummit and two days of conference during Sakura season in Tokyo, Japan The conference is also looking for sponsors If accepted, flight and hotel is paid for by the conference ###Project Trident 18.12 Released Twitter account if you want to keep up on project news Screenshots Project Trident Community Telegram Channel DistroWatch Page LinuxActionNews Review RoboNuggie’s in depth review ###Building Spotifyd on NetBSD These are the steps I went through to build and run Spotifyd (this commit at the time of writing) on NetBSD AMD64. It’s a Spotify Connect client so it means I still need to control Spotify from another device (typically my phone), but the audio is played through my desktop… which is where my speakers and headphones are plugged in - it means I don’t have to unplug stuff and re-plug into my phone, work laptop, etc. This is 100% a “good enough for now solution” for me; I have had a quick play with the Go based microcontroller from spotcontrol and that allows a completely NetBSD only experience (although it is just an example application so doesn’t provide many features - great as a basis to build on though). ##News Roundup ###OPNsense 18.7.10 released 2019 means 19.1 is almost here. In the meantime accept this small incremental update with goodies such as Suricata 4.1, custom passwords for P12 certificate export as well as fresh fixes in the FreeBSD base. A lot of cleanups went into this update to make sure there will be a smooth transition to 19.1-RC for you early birds. We expect RC1 in 1-2 weeks and the final 19.1 on January 29. ###Introducing the Ultra EPYC AMD Powered Sun Ultra 24 Workstation A few weeks ago, I got an itch to build a workstation with AMD EPYC. There are a few constraints. First, I needed a higher-clock part. Second, I knew the whole build would be focused more on being an ultra high-end workstation rather than simply utilizing gaming components. With that, I decided it was time to hit on a bit of nostalgia for our readers. Mainly, I wanted to do an homage to Sun Microsystems. Sun made the server gear that the industry ran on for years, and as a fun fact, if you go behind the 1 Hacker Way sign at Facebook’s campus, they left the Sun Microsystems logo. Seeing that made me wonder if we could do an ultimate AMD EPYC build in a Sun Microsystems workstation. ###OpenRsync This is a clean-room implementation of rsync with a BSD (ISC) license. It is designed to be compatible with a modern rsync (3.1.3 is used for testing). It currently compiles and runs only on OpenBSD. This project is still very new and very fast-moving. It’s not ready for wide-spread testing. Or even narrow-spread beyond getting all of the bits to work. It’s not ready for strong attention. Or really any attention but by careful programming. Many have asked about portability. We’re just not there yet, folks. But don’t worry, the system is easily portable. The hard part for porters is matching OpenBSD’s pledge and unveil. ###The first report on LLD porting LLD is the link editor (linker) component of Clang toolchain. Its main advantage over GNU ld is much lower memory footprint, and linking speed. It is of specific interest to me since currently 8 GiB of memory are insufficient to link LLVM statically (which is the upstream default). The first goal of LLD porting is to ensure that LLD can produce working NetBSD executables, and be used to build LLVM itself. Then, it is desirable to look into trying to build additional NetBSD components, and eventually into replacing /usr/bin/ld entirely with lld. In this report, I would like to shortly summarize the issues I have found so far trying to use LLD on NetBSD. ###Ring in the new It’s the second week of 2019 already, which means I’m curious what Nate is going to do with his series This week in usability … reset the numbering from week 1? That series is a great read, to keep up with all the little things that change in KDE source each week — aside from the release notes. For the big ticket items of KDE on FreeBSD, you should read this blog instead. In ports this week (mostly KDE, some unrelated): KDE Plasma has been updated to the latest release, 5.14.5. KDE Applications 18.12.1 were released today, so we’re right on top of them. Marble was fixed for FreeBSD-running-on-Power9. Musescore caught up on 18 months of releases. Phonon updated to 4.10.1, along with its backends. And in development, Qt WebEngine 5.12 has been prepared in the incongruously-named plasma-5.13 branch in Area51; that does contain all the latest bits described above, as well. ##Beastie Bits NomadBSD 1.2-RC1 Released ZFS - The First Enterprise Blockchain Powersaving with DragonFly laptop NetBSD reaches 100% reproducable builds Potential Bhyve Web Interface?

Hace un año, Linux Mint lanzó una característica muy interesante en forma de aplicación llamada Timeshift. Timeshift permite guardar copias de seguridad del sistema de forma automatizada al más puro estilo de Time Machine en Mac OS. Gracias a Timeshift, los usuarios de GNU Linux, podemos toquetear, instalar servicios, etc, sin miedo alguno a corromper el sistema, ya que siempre podremos volver a un sistema estable con Timeshift. He probado a instalarlo en mi Manjaro Arch Linux y mi sorpresa ha sido que esta herramienta se encuentra en los repositorios oficiales. Instalar Timeshift en Manjaro es tan facil como teclear en la terminal "sudo pacman -S timeshift" y ya está. Si usas Manjaro, ya estás tardando en instalarla y si eres usuario de otras distribuciones segurop que no vas a tener ningún problema en instalarla. Lo único que necesitas para que funcione bien es tener conectado un disco duro externo en formato Ext4 para que el formato Rsync de Timeshift pueda hacer ahí la copia.

We report from our experiences at EuroBSDcon, disenchant software, LLVM 7.0.0 has been released, Thinkpad BIOS update options, HardenedBSD Foundation announced, and ZFS send vs. rsync. ##Headlines ###[FreeBSD DevSummit & EuroBSDcon 2018 in Romania] Your hosts are back from EuroBSDcon 2018 held in Bucharest, Romania this year. The first two days of the conference are used for tutorials and devsummits (FreeBSD and NetBSD), while the last two are for talks. Although Benedict organized the devsummit in large parts, he did not attend it this year. He held his Ansible tutorial in the morning of the first day, followed by Niclas Zeising’s new ports and poudriere tutorial (which had a record attendance). It was intended for beginners that had never used poudriere before and those who wanted to create their first port. The tutorial was well received and Niclas already has ideas for extending it for future conferences. On the second day, Benedict took Kirk McKusick’s “An Introduction to the FreeBSD Open-Source Operating System” tutorial, held as a one full day class this year. Although it was reduced in content, it went into enough depth of many areas of the kernel and operating system to spark many questions from attendees. Clearly, this is a good start into kernel programming as Kirk provides enough material and backstories to understand why certain things are implemented as they are. Olivier Robert took https://www.talegraph.com/tales/l2o9ltrvsE (pictures from the devsummit) and created a nice gallery out of it. Devsummit evenings saw dinners at two restaurants that allowed developers to spend some time talking over food and drinks. The conference opened on the next day with the opening session held by Mihai Carabas. He introduced the first keynote speaker, a colleague of his who presented “Lightweight virtualization with LightVM and Unikraft”. Benedict helped out at the FreeBSD Foundation sponsor table and talked to people. He saw the following talks in between: Selfhosting as an alternative to the public cloud (by Albert Dengg) Using Boot Environments at Scale (by Allan Jude) Livepatching FreeBSD kernel (by Maciej Grochowski) FreeBSD: What to (Not) Monitor (by Andrew Fengler) FreeBSD Graphics (by Niclas Zeising) Allan spent a lot of time talking to people and helping track down issues they were having, in addition to attending many talks: Hacking together a FreeBSD presentation streaming box – For as little as possible (by Tom Jones) Introduction of FreeBSD in new environments (by Baptiste Daroussin) Keynote: Some computing and networking historical perspectives (by Ron Broersma) Livepatching FreeBSD kernel (by Maciej Grochowski) FreeBSD: What to (Not) Monitor (by Andrew Fengler) Being a BSD user (by Roller Angel) From “Hello World” to the VFS Layer: building a beadm for DragonFly BSD (by Michael Voight) We also met the winner of our Power Bagel raffle from Episode 2^8. He received the item in the meantime and had it with him at the conference, providing a power outlet to charge other people’s devices. During the closing session, GroffTheBSDGoat was handed over to Deb Goodkin, who will bring the little guy to the Grace Hopper Celebration of Women in Computing conference and then to MeetBSD later this year. It was also revealed that next year’s EuroBSDcon will be held in Lillehammer, Norway. Thanks to all the speakers, helpers, sponsors, organizers, and attendees for making it a successful conferences. There were no talks recorded this year, but the slides will be uploaded to the EuroBSDcon website in a couple of weeks. The OpenBSD talks are already available, so check them out. ###Software disenchantment I’ve been programming for 15 years now. Recently our industry’s lack of care for efficiency, simplicity, and excellence started really getting to me, to the point of me getting depressed by my own career and the IT in general. Modern cars work, let’s say for the sake of argument, at 98% of what’s physically possible with the current engine design. Modern buildings use just enough material to fulfill their function and stay safe under the given conditions. All planes converged to the optimal size/form/load and basically look the same. Only in software, it’s fine if a program runs at 1% or even 0.01% of the possible performance. Everybody just seems to be ok with it. People are often even proud about how much inefficient it is, as in “why should we worry, computers are fast enough”: @tveastman: I have a Python program I run every day, it takes 1.5 seconds. I spent six hours re-writing it in rust, now it takes 0.06 seconds. That efficiency improvement means I’ll make my time back in 41 years, 24 days :-) You’ve probably heard this mantra: “programmer time is more expensive than computer time”. What it means basically is that we’re wasting computers at an unprecedented scale. Would you buy a car if it eats 100 liters per 100 kilometers? How about 1000 liters? With computers, we do that all the time. Everything is unbearably slow Look around: our portable computers are thousands of times more powerful than the ones that brought man to the moon. Yet every other webpage struggles to maintain a smooth 60fps scroll on the latest top-of-the-line MacBook Pro. I can comfortably play games, watch 4K videos but not scroll web pages? How is it ok? Google Inbox, a web app written by Google, running in Chrome browser also by Google, takes 13 seconds to open moderately-sized emails: It also animates empty white boxes instead of showing their content because it’s the only way anything can be animated on a webpage with decent performance. No, decent doesn’t mean 60fps, it’s rather “as fast as this web page could possibly go”. I’m dying to see web community answer when 120Hz displays become mainstream. Shit barely hits 60Hz already. Windows 10 takes 30 minutes to update. What could it possibly be doing for that long? That much time is enough to fully format my SSD drive, download a fresh build and install it like 5 times in a row. Pavel Fatin: Typing in editor is a relatively simple process, so even 286 PCs were able to provide a rather fluid typing experience. Modern text editors have higher latency than 42-year-old Emacs. Text editors! What can be simpler? On each keystroke, all you have to do is update tiny rectangular region and modern text editors can’t do that in 16ms. It’s a lot of time. A LOT. A 3D game can fill the whole screen with hundreds of thousands (!!!) of polygons in the same 16ms and also process input, recalculate the world and dynamically load/unload resources. How come? As a general trend, we’re not getting faster software with more features. We’re getting faster hardware that runs slower software with the same features. Everything works way below the possible speed. Ever wonder why your phone needs 30 to 60 seconds to boot? Why can’t it boot, say, in one second? There are no physical limitations to that. I would love to see that. I would love to see limits reached and explored, utilizing every last bit of performance we can get for something meaningful in a meaningful way. Everything is HUUUUGE And then there’s bloat. Web apps could open up to 10× faster if you just simply block all ads. Google begs everyone to stop shooting themselves in their feet with AMP initiative—a technology solution to a problem that doesn’t need any technology, just a little bit of common sense. If you remove bloat, the web becomes crazy fast. How smart do you have to be to understand that? Android system with no apps takes almost 6 Gb. Just think for a second how obscenely HUGE that number is. What’s in there, HD movies? I guess it’s basically code: kernel, drivers. Some string and resources too, sure, but those can’t be big. So, how many drivers do you need for a phone? Windows 95 was 30Mb. Today we have web pages heavier than that! Windows 10 is 4Gb, which is 133 times as big. But is it 133 times as superior? I mean, functionally they are basically the same. Yes, we have Cortana, but I doubt it takes 3970 Mb. But whatever Windows 10 is, is Android really 150% of that? Google keyboard app routinely eats 150 Mb. Is an app that draws 30 keys on a screen really five times more complex than the whole Windows 95? Google app, which is basically just a package for Google Web Search, is 350 Mb! Google Play Services, which I do not use (I don’t buy books, music or videos there)—300 Mb that just sit there and which I’m unable to delete. All that leaves me around 1 Gb for my photos after I install all the essential (social, chats, maps, taxi, banks etc) apps. And that’s with no games and no music at all! Remember times when an OS, apps and all your data fit on a floppy? Your desktop todo app is probably written in Electron and thus has userland driver for Xbox 360 controller in it, can render 3d graphics and play audio and take photos with your web camera. A simple text chat is notorious for its load speed and memory consumption. Yes, you really have to count Slack in as a resource-heavy application. I mean, chatroom and barebones text editor, those are supposed to be two of the less demanding apps in the whole world. Welcome to 2018. At least it works, you might say. Well, bigger doesn’t imply better. Bigger means someone has lost control. Bigger means we don’t know what’s going on. Bigger means complexity tax, performance tax, reliability tax. This is not the norm and should not become the norm. Overweight apps should mean a red flag. They should mean run away scared. Better world manifesto I want to see progress. I want change. I want state-of-the-art in software engineering to improve, not just stand still. I don’t want to reinvent the same stuff over and over, less performant and more bloated each time. I want something to believe in, a worthy end goal, a future better than what we have today, and I want a community of engineers who share that vision. What we have today is not progress. We barely meet business goals with poor tools applied over the top. We’re stuck in local optima and nobody wants to move out. It’s not even a good place, it’s bloated and inefficient. We just somehow got used to it. So I want to call it out: where we are today is bullshit. As engineers, we can, and should, and will do better. We can have better tools, we can build better apps, faster, more predictable, more reliable, using fewer resources (orders of magnitude fewer!). We need to understand deeply what are we doing and why. We need to deliver: reliably, predictably, with topmost quality. We can—and should–take pride in our work. Not just “given what we had…”—no buts! I hope I’m not alone at this. I hope there are people out there who want to do the same. I’d appreciate if we at least start talking about how absurdly bad our current situation in the software industry is. And then we maybe figure out how to get out. ##News Roundup [llvm-announce] LLVM 7.0.0 Release I am pleased to announce that LLVM 7 is now available.

With OpenBSD: $ doas pkgadd geteltorito quirks-3.7 signed on 2018-09-09T13:15:19Z geteltorito-0.6: ok With Debian: $ sudo apt-get install genisoimage Now we will extract the bios update : $ geteltorito -o biosupdate.img r0iuj25wd.iso Booting catalog starts at sector: 20 Manufacturer of CD: NERO BURNING ROM VER 12 Image architecture: x86 Boot media type is: harddisk El Torito image starts at sector 27 and has 43008 sector(s) of 512 Bytes Image has been written to file "biosupdate.img". This will create a file called biosupdate.img. Put the image on an USB key CAREFULL : on my computer, my USB key is sda1 on Linux and sd1 on OpenBSD. Please check twice on your computer the name of your USB key. With OpenBSD : $ doas dd if=biosupdate.img of=/dev/rsd1c With Linux : $ sudo dd if=biosupdate.img of=/dev/sda Now all you need is to reboot, to boot on your USB key and follow the instructions. Enjoy 😉 ###Announcing The HardenedBSD Foundation In June of 2018, we announced our intent to become a not-for-profit, tax-exempt 501©(3) organization in the United States. It took a dedicated team months of work behind-the-scenes to make that happen. On 06 September 2018, HardenedBSD Foundation Corp was granted 501©(3) status, from which point all US-based persons making donations can deduct the donation from their taxes. We are grateful for those who contribute to HardenedBSD in whatever way they can. Thank you for making HardenedBSD possible. We look forward to a bright future, driven by a helpful and positive community. ###How you migrate ZFS filesystems matters If you want to move a ZFS filesystem around from one host to another, you have two general approaches; you can use ‘zfs send’ and ‘zfs receive’, or you can use a user level copying tool such as rsync (or ‘tar -cf | tar -xf’, or any number of similar options). Until recently, I had considered these two approaches to be more or less equivalent apart from their convenience and speed (which generally tilted in favour of ‘zfs send’). It turns out that this is not necessarily the case and there are situations where you will want one instead of the other. We have had two generations of ZFS fileservers so far, the Solaris ones and the OmniOS ones. When we moved from the first generation to the second generation, we migrated filesystems across using ‘zfs send’, including the filesystem with my home directory in it (we did this for various reasons). Recently I discovered that some old things in my filesystem didn’t have file type information in their directory entries. ZFS has been adding file type information to directories for a long time, but not quite as long as my home directory has been on ZFS. This illustrates an important difference between the ‘zfs send’ approach and the rsync approach, which is that zfs send doesn’t update or change at least some ZFS on-disk data structures, in the way that re-writing them from scratch from user level does. There are both positives and negatives to this, and a certain amount of rewriting does happen even in the ‘zfs send’ case (for example, all of the block pointers get changed, and ZFS will re-compress your data as applicable). I knew that in theory you had to copy things at the user level if you wanted to make sure that your ZFS filesystem and everything in it was fully up to date with the latest ZFS features. But I didn’t expect to hit a situation where it mattered in practice until, well, I did. Now I suspect that old files on our old filesystems may be partially missing a number of things, and I’m wondering how much of the various changes in ‘zfs upgrade -v’ apply even to old data. (I’d run into this sort of general thing before when I looked into ext3 to ext4 conversion on Linux.) With all that said, I doubt this will change our plans for migrating our ZFS filesystems in the future (to our third generation fileservers). ZFS sending and receiving is just too convenient, too fast and too reliable to give up. Rsync isn’t bad, but it’s not the same, and so we only use it when we have to (when we’re moving only some of the people in a filesystem instead of all of them, for example). PS: I was going to try to say something about what ‘zfs send’ did and didn’t update, but having looked briefly at the code I’ve concluded that I need to do more research before running my keyboard off. In the mean time, you can read the OpenZFS wiki page on ZFS send and receive, which has plenty of juicy technical details. PPS: Since eliminating all-zero blocks is a form of compression, you can turn zero-filled files into sparse files through a ZFS send/receive if the destination has compression enabled. As far as I know, genuine sparse files on the source will stay sparse through a ZFS send/receive even if they’re sent to a destination with compression off. ##Beastie Bits BSD Users Stockholm Meetup #4: Tuesday, November 13, 2018 at 18:00 BSD Poland User Group: Next Meeting: October 11, 2018, 18:15 - 21:15 at Warsaw University of Technology n2k18 Hackathon report: Ken Westerback (krw@) on disklabel(8) work, dhclient(8) progress Running MirageOS Unikernels on OpenBSD in vmm (Now Works) vmm(4) gets support for qcow2 MeetBSD and SecurityBsides Colin Percival reduced FreeBSD startup time from 10627ms (11.2) to 4738ms (12.0) FreeBSD 11.1 end-of-life KnoxBug: Monday, October 1, 2018 at 18:00: Real-world Performance Advantages of NVDIMM and NVMe: Case Study with OpenZFS ##Feedback/Questions Todd - 2 Nics, 1 bhyve and a jail cell Thomas - Deep Dive Morgan - Send/Receive to Manage Fragmentation?

OpenZFS and DTrace updates in NetBSD, NetBSD network security stack audit, Performance of MySQL on ZFS, OpenSMTP results from p2k18, legacy Windows backup to FreeNAS, ZFS block size importance, and NetBSD as router on a stick. ##Headlines ZFS and DTrace update lands in NetBSD merge a new version of the CDDL dtrace and ZFS code. This changes the upstream vendor from OpenSolaris to FreeBSD, and this version is based on FreeBSD svn r315983. r315983 is from March 2017 (14 months ago), so there is still more work to do in addition to the 10 years of improvements from upstream, this version also has these NetBSD-specific enhancements: dtrace FBT probes can now be placed in kernel modules. ZFS now supports mmap(). This brings NetBSD 10 years forward, and they should be able to catch the rest of the way up fairly quickly ###NetBSD network stack security audit Maxime Villard has been working on an audit of the NetBSD network stack, a project sponsored by The NetBSD Foundation, which has served all users of BSD-derived operating systems. Over the last five months, hundreds of patches were committed to the source tree as a result of this work. Dozens of bugs were fixed, among which a good number of actual, remotely-triggerable vulnerabilities. Changes were made to strengthen the networking subsystems and improve code quality: reinforce the mbuf API, add many KASSERTs to enforce assumptions, simplify packet handling, and verify compliance with RFCs. This was done in several layers of the NetBSD kernel, from device drivers to L4 handlers. In the course of investigating several bugs discovered in NetBSD, I happened to look at the network stacks of other operating systems, to see whether they had already fixed the issues, and if so how. Needless to say, I found bugs there too. A lot of code is shared between the BSDs, so it is especially helpful when one finds a bug, to check the other BSDs and share the fix. The IPv6 Buffer Overflow: The overflow allowed an attacker to write one byte of packet-controlled data into ‘packetstorage+off’, where ‘off’ could be approximately controlled too. This allowed at least a pretty bad remote DoS/Crash The IPsec Infinite Loop: When receiving an IPv6-AH packet, the IPsec entry point was not correctly computing the length of the IPv6 suboptions, and this, before authentication. As a result, a specially-crafted IPv6 packet could trigger an infinite loop in the kernel (making it unresponsive). In addition this flaw allowed a limited buffer overflow - where the data being written was however not controllable by the attacker. The IPPROTO Typo: While looking at the IPv6 Multicast code, I stumbled across a pretty simple yet pretty bad mistake: at one point the Pim6 entry point would return IPPROTONONE instead of IPPROTODONE. Returning IPPROTONONE was entirely wrong: it caused the kernel to keep iterating on the IPv6 packet chain, while the packet storage was already freed. The PF Signedness Bug: A bug was found in NetBSD’s implementation of the PF firewall, that did not affect the other BSDs. In the initial PF code a particular macro was used as an alias to a number. This macro formed a signed integer. NetBSD replaced the macro with a sizeof(), which returns an unsigned result. The NPF Integer Overflow: An integer overflow could be triggered in NPF, when parsing an IPv6 packet with large options. This could cause NPF to look for the L4 payload at the wrong offset within the packet, and it allowed an attacker to bypass any L4 filtering rule on IPv6. The IPsec Fragment Attack: I noticed some time ago that when reassembling fragments (in either IPv4 or IPv6), the kernel was not removing the MPKTHDR flag on the secondary mbufs in mbuf chains. This flag is supposed to indicate that a given mbuf is the head of the chain it forms; having the flag on secondary mbufs was suspicious. What Now: Not all protocols and layers of the network stack were verified, because of time constraints, and also because of unexpected events: the recent x86 CPU bugs, which I was the only one able to fix promptly. A todo list will be left when the project end date is reached, for someone else to pick up. Me perhaps, later this year? We’ll see. This security audit of NetBSD’s network stack is sponsored by The NetBSD Foundation, and serves all users of BSD-derived operating systems. The NetBSD Foundation is a non-profit organization, and welcomes any donations that help continue funding projects of this kind. DigitalOcean ###MySQL on ZFS Performance I used sysbench to create a table of 10M rows and then, using export/import tablespace, I copied it 329 times. I ended up with 330 tables for a total size of about 850GB. The dataset generated by sysbench is not very compressible, so I used lz4 compression in ZFS. For the other ZFS settings, I used what can be found in my earlier ZFS posts but with the ARC size limited to 1GB. I then used that plain configuration for the first benchmarks. Here are the results with the sysbench point-select benchmark, a uniform distribution and eight threads. The InnoDB buffer pool was set to 2.5GB. In both cases, the load is IO bound. The disk is doing exactly the allowed 3000 IOPS. The above graph appears to be a clear demonstration that XFS is much faster than ZFS, right? But is that really the case? The way the dataset has been created is extremely favorable to XFS since there is absolutely no file fragmentation. Once you have all the files opened, a read IOP is just a single fseek call to an offset and ZFS doesn’t need to access any intermediate inode. The above result is about as fair as saying MyISAM is faster than InnoDB based only on table scan performance results of unfragmented tables and default configuration. ZFS is much less affected by the file level fragmentation, especially for point access type. ZFS stores the files in B-trees in a very similar fashion as InnoDB stores data. To access a piece of data in a B-tree, you need to access the top level page (often called root node) and then one block per level down to a leaf-node containing the data. With no cache, to read something from a three levels B-tree thus requires 3 IOPS. The extra IOPS performed by ZFS are needed to access those internal blocks in the B-trees of the files. These internal blocks are labeled as metadata. Essentially, in the above benchmark, the ARC is too small to contain all the internal blocks of the table files’ B-trees. If we continue the comparison with InnoDB, it would be like running with a buffer pool too small to contain the non-leaf pages. The test dataset I used has about 600MB of non-leaf pages, about 0.1% of the total size, which was well cached by the 3GB buffer pool. So only one InnoDB page, a leaf page, needed to be read per point-select statement. To correctly set the ARC size to cache the metadata, you have two choices. First, you can guess values for the ARC size and experiment. Second, you can try to evaluate it by looking at the ZFS internal data. Let’s review these two approaches. You’ll read/hear often the ratio 1GB of ARC for 1TB of data, which is about the same 0.1% ratio as for InnoDB. I wrote about that ratio a few times, having nothing better to propose. Actually, I found it depends a lot on the recordsize used. The 0.1% ratio implies a ZFS recordsize of 128KB. A ZFS filesystem with a recordsize of 128KB will use much less metadata than another one using a recordsize of 16KB because it has 8x fewer leaf pages. Fewer leaf pages require less B-tree internal nodes, hence less metadata. A filesystem with a recordsize of 128KB is excellent for sequential access as it maximizes compression and reduces the IOPS but it is poor for small random access operations like the ones MySQL/InnoDB does. In order to improve ZFS performance, I had 3 options: Increase the ARC size to 7GB Use a larger Innodb page size like 64KB Add a L2ARC I was reluctant to grow the ARC to 7GB, which was nearly half the overall system memory. At best, the ZFS performance would only match XFS. A larger InnoDB page size would increase the CPU load for decompression on an instance with only two vCPUs; not great either. The last option, the L2ARC, was the most promising. ZFS is much more complex than XFS and EXT4 but, that also means it has more tunables/options. I used a simplistic setup and an unfair benchmark which initially led to poor ZFS results. With the same benchmark, very favorable to XFS, I added a ZFS L2ARC and that completely reversed the situation, more than tripling the ZFS results, now 66% above XFS. Conclusion We have seen in this post why the general perception is that ZFS under-performs compared to XFS or EXT4. The presence of B-trees for the files has a big impact on the amount of metadata ZFS needs to handle, especially when the recordsize is small. The metadata consists mostly of the non-leaf pages (or internal nodes) of the B-trees. When properly cached, the performance of ZFS is excellent. ZFS allows you to optimize the use of EBS volumes, both in term of IOPS and size when the instance has fast ephemeral storage devices. Using the ephemeral device of an i3.large instance for the ZFS L2ARC, ZFS outperformed XFS by 66%. ###OpenSMTPD new config TL;DR: OpenBSD #p2k18 hackathon took place at Epitech in Nantes. I was organizing the hackathon but managed to make progress on OpenSMTPD. As mentioned at EuroBSDCon the one-line per rule config format was a design error. A new configuration grammar is almost ready and the underlying structures are simplified. Refactor removes ~750 lines of code and solves _many issues that were side-effects of the design error. New features are going to be unlocked thanks to this. Anatomy of a design error OpenSMTPD started ten years ago out of dissatisfaction with other solutions, mainly because I considered them way too complex for me not to get things wrong from time to time. The initial configuration format was very different, I was inspired by pyr@’s hoststated, which eventually became relayd, and designed my configuration format with blocks enclosed by brackets. When I first showed OpenSMTPD to pyr@, he convinced me that PF-like one-line rules would be awesome, and it was awesome indeed. It helped us maintain our goal of simple configuration files, it helped fight feature creeping, it helped us gain popularity and become a relevant MTA, it helped us get where we are now 10 years later. That being said, I believe this was a design error. A design error that could not have been predicted until we hit the wall to understand WHY this was an error. One-line rules are semantically wrong, they are SMTP wrong, they are wrong. One-line rules are making the entire daemon more complex, preventing some features from being implemented, making others more complex than they should be, they no longer serve our goals. To get to the point: we should move to two-line rules :-) Anatomy of a design error OpenSMTPD started ten years ago out of dissatisfaction with other solutions, mainly because I considered them way too complex for me not to get things wrong from time to time.

One-line rules are making the entire daemon more complex, preventing some features from being implemented, making others more complex than they should be, they no longer serve our goals. To get to the point: we should move to two-line rules :-) The problem with one-line rules OpenSMTPD decides to accept or reject messages based on one-line rules such as: accept from any for domain poolp.org deliver to mbox Which can essentially be split into three units: the decision: accept/reject the matching: from any for domain poolp.org the (default) action: deliver to mbox To ensure that we meet the requirements of the transactions, the matching must be performed during the SMTP transaction before we take a decision for the recipient. Given that the rule is atomic, that it doesn’t have an identifier and that the action is part of it, the two only ways to make sure we can remember the action to take later on at delivery time is to either: save the action in the envelope, which is what we do today evaluate the envelope again at delivery And this this where it gets tricky… both solutions are NOT ok. The first solution, which we’ve been using for a decade, was to save the action within the envelope and kind of carve it in stone. This works fine… however it comes with the downsides that errors fixed in configuration files can’t be caught up by envelopes, that delivery action must be validated way ahead of time during the SMTP transaction which is much trickier, that the parsing of delivery methods takes place as the _smtpd user rather than the recipient user, and that envelope structures that are passed all over OpenSMTPD carry delivery-time informations, and more, and more, and more. The code becomes more complex in general, less safe in some particular places, and some areas are nightmarish to deal with because they have to deal with completely unrelated code that can’t be dealt with later in the code path. The second solution can’t be done. An envelope may be the result of nested rules, for example an external client, hitting an alias, hitting a user with a .forward file resolving to a user. An envelope on disk may no longer match any rule or it may match a completely different rule If we could ensure that it matched the same rule, evaluating the ruleset may spawn new envelopes which would violate the transaction. Trying to imagine how we could work around this leads to more and more and more RFC violations, incoherent states, duplicate mails, etc… There is simply no way to deal with this with atomic rules, the matching and the action must be two separate units that are evaluated at two different times, failure to do so will necessarily imply that you’re either using our first solution and all its downsides, or that you are currently in a world of pain trying to figure out why everything is burning around you. The minute the action is written to an on-disk envelope, you have failed. A proper ruleset must define a set of matching patterns resolving to an action identifier that is carved in stone, AND a set of named action set that is resolved dynamically at delivery time.

It has been working great for me. First of all, I do have my Windows servers backup in virtualized format. However, those are only one-time snapshops that I run once in a while. These are classic ASP IIS web servers that I can easily put up on a new VM. However, many of these legacy servers generate gigabytes of data a day in their repositories. Running VM conversion daily is not ideal. My solution was to use some sort of rsync solution just for the data repos. I’ve tried some applications that didn’t work too well with Samba shares and these old servers have slow I/O. Copying files to external sata or usb drive was not ideal. We’ve moved on from Windows to Linux and do not have any Windows file servers of capacity to provide network backups. Hence, I decided to use Delta Copy with FreeNAS. So here is a little write up on how to set it up. I have 4 Windows 2000 servers backing up daily with this method. First, download Delta Copy and install it. It is open-source and pretty much free. It is basically a wrapper for cygwin’s rsync. When you install it, it will ask you to install the Server services which allows you to run it as a Rsync server on Windows. You don’t need to do this. Instead, you will be just using the Delta Copy Client application. But before we do that, we will need to configure our Rsync service for our Windows Clients on FreeNAS. In FreeNAS, go under Services , Select Rsync > Rsync Modules > Add Rsync Module. Then fill out the form; giving the module a name and set the path. In my example, I simply called it WIN and linked it to a user called backupuser. This process is much easier than trying to configure the daemon rsyncd.conf file by hand. Now, on the Windows Client, start the DeltaCopy Client. You will create a new Profile. You will need to enter the IP of the Rsync server (FreeNAS) and specify the module name which will be called “Virtual Directory Name.” When you pull the select menu, the list of Rsync Modules you created earlier in FreeNAS will populate. You can set authentication. On the server, you can restrict by IP and do other things to lock down your rsync. Next, you will add folders (and/or files) you want to synchronize. Once the paths are set up, you can run a sync by right clicking the profile name. Here, I made a test sync to a home folder of a virtualized windows box. As you can see, I mounted the rsync volume on my mac to see the progress. The rsync worked beautifully. DeltaCopy did what it was told. Once you get everything working. The next thing to do is set schedules. If you done tasks schedules in Windows before, it is pretty straightforward. DeltaCopy has a link in the application to directly create a new task for you. I set my backups to run nightly and it has been working great. There you have it. Windows rsync to FreeNAS using DeltaCopy. The nice thing about FreeNAS is you don’t have to modify /etc/rsyncd.conf files. Everything can be done in the web admin. iXsystems ###How to write ATF tests for NetBSD I have recently started contributing to the amazing NetBSD foundation. I was thinking of trying out a new OS for a long time. Switching to the NetBSD OS has been a fun change. My first contribution to the NetBSD foundation was adding regression tests for the Address Sanitizer (ASan) in the Automated Testing Framework(ATF) which NetBSD has. I managed to complete it with the help of my really amazing mentor Kamil. This post is gonna be about the ATF framework that NetBSD has and how to you can add multiple tests with ease. Intro In ATF tests we will basically be talking about test programs which are a suite of test cases for a specific application or program. The ATF suite of Commands There are a variety of commands that the atf suite offers. These include : atf-check: The versatile command that is a vital part of the checking process. man page atf-run: Command used to run a test program. man page atf-fail: Report failure of a test case. atf-report: used to pretty print the atf-run. man page atf-set: To set atf test conditions. We will be taking a better look at the syntax and usage later. Let’s start with the Basics The ATF testing framework comes preinstalled with a default NetBSD installation. It is used to write tests for various applications and commands in NetBSD. One can write the Test programs in either the C language or in shell script. In this post I will be dealing with the Bash part. Follow the link above to see the rest of the article ###The Importance of ZFS Block Size Warning! WARNING! Don’t just do things because some random blog says so One of the important tunables in ZFS is the recordsize (for normal datasets) and volblocksize (for zvols). These default to 128KB and 8KB respectively. As I understand it, this is the unit of work in ZFS. If you modify one byte in a large file with the default 128KB record size, it causes the whole 128KB to be read in, one byte to be changed, and a new 128KB block to be written out. As a result, the official recommendation is to use a block size which aligns with the underlying workload: so for example if you are using a database which reads and writes 16KB chunks then you should use a 16KB block size, and if you are running VMs containing an ext4 filesystem, which uses a 4KB block size, you should set a 4KB block size You can see it has a 16GB total file size, of which 8.5G has been touched and consumes space - that is, it’s a “sparse” file. The used space is also visible by looking at the zfs filesystem which this file resides in Then I tried to copy the image file whilst maintaining its “sparseness”, that is, only touching the blocks of the zvol which needed to be touched. The original used only 8.42G, but the copy uses 14.6GB - almost the entire 16GB has been touched! What’s gone wrong? I finally realised that the difference between the zfs filesystem and the zvol is the block size. I recreated the zvol with a 128K block size That’s better. The disk usage of the zvol is now exactly the same as for the sparse file in the filesystem dataset It does impact the read speed too. 4K blocks took 5:52, and 128K blocks took 3:20 Part of this is the amount of metadata that has to be read, see the MySQL benchmarks from earlier in the show And yes, using a larger block size will increase the compression efficiency, since the compressor has more redundant data to optimize. Some of the savings, and the speedup is because a lot less metadata had to be written Your zpool layout also plays a big role, if you use 4Kn disks, and RAID-Z2, using a volblocksize of 8k will actually result in a large amount of wasted space because of RAID-Z padding. Although, if you enable compression, your 8k records may compress to only 4k, and then all the numbers change again. ###Using a Raspberry Pi 2 as a Router on a Stick Starring NetBSD Sorry we didn’t answer you quickly enough A few weeks ago I set about upgrading my feeble networking skills by playing around with a Cisco 2970 switch. I set up a couple of VLANs and found the urge to set up a router to route between them. The 2970 isn’t a modern layer 3 switch so what am I to do? Why not make use of the Raspberry Pi 2 that I’ve never used and put it to some good use as a ‘router on a stick’. I could install a Linux based OS as I am quite familiar with it but where’s the fun in that? In my home lab I use SmartOS which by the way is a shit hot hypervisor but as far as I know there aren’t any Illumos distributions for the Raspberry Pi. On the desktop I use Solus OS which is by far the slickest Linux based OS that I’ve had the pleasure to use but Solus’ focus is purely desktop. It’s looking like BSD then! I believe FreeBSD is renowned for it’s top notch networking stack and so I wrote to the BSDNow show on Jupiter Broadcasting for some help but it seems that the FreeBSD chaps from the show are off on a jolly to some BSD conference or another(love the show by the way). It looks like me and the luvverly NetBSD are on a date this Saturday. I’ve always had a secret love for NetBSD. She’s a beautiful, charming and promiscuous lover(looking at the supported architectures) and I just can’t stop going back to her despite her misgivings(ahem, zfs). Just my type of grrrl!

This week, Allan is out of town at another Developer Summit, but we have a great episode coming This episode was brought to you by iX Systems Mission Complete (https://www.ixsystems.com/missioncomplete/) Submit your story of how you accomplished a mission with FreeBSD, FreeNAS, or iXsystems hardware, and you could win monthly prizes, and have your story featured in the FreeBSD Journal! *** Headlines WhatsApp founder, on how it got so HUGE (http://www.wired.com/2015/10/whatsapps-co-founder-on-how-the-iconoclastic-app-got-huge/) Wired has interviewed WhatsApp co-founder Brian Acton, about the infrastructure behind WhatsApp WhatsApp manages 900 million users with a team of 50, while Twitter needs around 4,000 employees to manage 300 million users. “FreeBSD has a nicely tuned network stack and extremely good reliability. We find managing FreeBSD installations to be quite straightforward.” “Linux is a beast of complexity. FreeBSD has the advantage of being a single distribution with an extraordinarily good ports collection.” “To us, it has been an advantage as we have had very few problems that have occurred at the OS level. With Linux, you tend to have to wrangle more and you want to avoid that if you can.” “FreeBSD happened because both Jan and I have experience with FreeBSD from Yahoo!.” Additional Coverage (http://uk.businessinsider.com/whatsapp-built-using-erlang-and-freebsd-2015-10) *** User feedback in the SystemD vs BSD init (https://www.textplain.net/blog/2015/problems-with-systemd-and-why-i-like-bsd-init/) We have a very detailed blog post this week from Randy Westlund, about his experiences on Linux and BSD, contrasting the init systems. What he finds is that while, it does make some things easier, such as writing a service file once, and having it run everywhere, the tradeoff comes in the complexity and lack of transparency. Another area of concern was the reproducibility of boots, how in his examples on servers, there can often be times when services start in different orders, to save a few moments of boot-time. His take on the simplicity of BSD's startup scripts is that they are very easy to hack on and monitor, while not introducing the feature creep we have seen in sysd. It will be interesting to see NextBSD / LaunchD and how it compares in the future! *** Learn to embrace open source, or get buried (http://opensource.com/business/15/10/ato-interview-jim-salter) At the recent “All Things Open” conference, opensource.com interviewed Jim Salter He describes how he first got started using FreeBSD to host his personal website He then goes on to talk about starting FreeBSDWiki.net and what its goals were The interview then talks about using Open Source at solve customers' problems at his consulting firm Finally, the talks about his presentation at AllThingsOpen: Move Over, Rsync (http://allthingsopen.org/talks/move-over-rsync/) about switching to ZFS replication *** HP's CTO Urges businesses to avoid permissive licenses (http://lwn.net/Articles/660428/) Martin Fink went on a rant about the negative effects of license proliferation While I agree that having too many new licenses is confusing and adds difficulty, I didn't agree with his closing point “He then ended the session with an extended appeal to move the open-source software industry away from permissive licenses like Apache 2.0 and toward copyleft licenses like the GPL” “The Apache 2.0 license is currently the most widely used "permissive" license. But the thing that developers overlook when adopting it, he said, is that by using Apache they are also making a choice about how much work they will have to put into building any sort of community around the project. If you look at Apache-licensed projects, he noted, "you'll find that they are very top-heavy with 'governance' structures." Technical committees, working groups, and various boards, he said, are needed to make such projects function. But if you look at copyleft projects, he added, you find that those structures simply are not needed.” There are plenty of smaller permissively licensed projects that do not have this sort of structure, infact, most of this structure comes from being an Apache run project, rather than from using the Apache or any other permissive license Luckily, he goes on to state that the “OpenSwitch code is released under the Apache 2.0 license, he said, because the other partner companies viewed that as a requirement.” “HP wanted to get networking companies and hardware suppliers on board. In order to get all of the legal departments at all of the partners to sign on to the project, he said, HP was forced to go with a permissive license” Hopefully the trend towards permissive licenses continues Additionally, in a separate LWN post: RMS Says: “I am not saying that competitors to a GNU package are unjust or bad -- that isn't necessarily so. The pertinent point is that they are competitors. The goal of the GNU Project is for GNU to win the competition. Each GNU package is a part of the GNU system, and should contribute to the success of the GNU Project. Thus, each GNU package should encourage people to run other GNU packages rather than their competitors -- even competitors which are free software.” (http://lwn.net/Articles/659757/) Never thought I'd see RMS espousing vendor lock-in *** Interview - Brian Callahan - bcallah@devio.us (mailto:bcallah@devio.us) / @twitter (https://twitter.com/__briancallahan) The BSDs in Education *** News Roundup Digital Libraries in Africa making use of DragonflyBSD and HAMMER (http://lists.dragonflybsd.org/pipermail/users/2015-October/228403.html) In the international development context, we have an interesting post from Michael Wilson of the PeerCorps Trust Fund. They are using DragonFlyBSD and FreeBSD to support the Tanzanian Digital Library Initiative in very resource-limited settings. They cite among the most important reasons for using BSD as the availability and quality of the documentation, as well as the robustness of the filesystems, both ZFS and HAMMER. Their website is now online over at (http://www.tandli.com/) , check it out to see exactly how BSD is being used in the field *** netflix hits > 65gbps from a single freebsd box (https://twitter.com/ed_maste/status/655120086248763396) A single socket server, with a high end Xeon E5 processor and a dual ported Chelsio T580 (2x 40 Gbps ports) set a netflix record pushing over 65 Gbps of traffic from a single machine The videos were being pushed from SSDs and some new high end NVMe devices The previous record at Netflix was 52 Gbps from a single machine, but only with very experimental settings. The current work is under much more typical settings By the end of that night, traffic surged to over 70 Gbps Only about 10-15% of that traffic was encrypted with the in-kernel TLS engine that Netflix has been working on with John-Mark Gurney It was reported that the machine was only using about 65% cpu, and had plenty of head room If I remember the discussion correctly, there were about 60,000 streams running off the machine *** Lumina Desktop 0.8.7 has been released (http://lumina-desktop.org/lumina-desktop-0-8-7-released/) A very large update has landed for PC-BSD's Lumina desktop A brand new “Start” menu has been added, which enables quick launch of favorite apps, pinning to desktop / favorites and more. Desktop icons have been overhauled, with better font support, and a new Grid system for placement of icons. Support for other BSD's such as DragonFly has been improved, along with TONS of internal changes to functionality and backends. Almost too many things to list here, but the link above will have full details, along with screenshots. *** A LiveUSB for NetBSD has been released by Jibbed (http://www.jibbed.org/) After a three year absence, the Jibbed project has come back with a Live USB image for NetBSD! The image contains NetBSD 7.0, and is fully R/W, allowing you to run the entire system from a single USB drive. Images are available for 8Gb and 4Gb sticks (64bit and 32bit respectively), along with VirtualBox images as well For those wanting X, it includes both X and TWM, although ‘pkgin' is available, so you can quickly add other desktops to the image *** Beastie Bits After recent discussions of revisiting W^X support in Mozilla Firefox, David Coppa has flipped the switch to enable it for OpenBSD users running -current.

Show notes Why roll your own? Privacy Storage Total control http://zenhabits.net/google-free/ Pros/cons of “Rolling your own {INSERT SERVICE HERE}”? Good option for young kids Cons 1. A dedicated server just for Zimbra with Domain Keys installed 2. A block of 24-32 ip numbers. (49 ip numbers would be ideal, but it’s harder to buy odd blocks like that.) Put your mail server as close to the middle of that range as possible. It sounds like a lot, but most collocation facilities can hook you up with this for 300-500 usd a month. 3. Proactive attention to getting your ip block removed from all spam lists (especially Barracuda, their list is the most annoying for the high number of false positives) before the fact. Just let them know you exist. 4. Pray that all of the hundreds of moving pieces you’ve just put in place don’t break, that bad hackers don’t brute force their way into your server. Strong passwords don’t really help as much as people tell you they do either. That’s now something you have to worry about too. Where to host?
