We read FreeBSD’s third quarterly status report, OpenBSD on Sparc64, ZoL repo move to OpenZFS, GEOM NOP, keeping NetBSD up-to-date, and more. Headlines FreeBSD third quarterly status report for 2019 (https://www.freebsd.org/news/status/report-2019-07-2019-09.html) This quarter the reports team has been more active than usual thanks to a better organization: calls for reports and reminders have been sent regularly, reports have been reviewed and merged quickly (I would like to thank debdrup@ in particular for his reviewing work). Efficiency could still be improved with the help of our community. In particular, the quarterly team has found that many reports have arrived in the last days before the deadline or even after. I would like to invite the community to follow the guidelines below that can help us sending out the reports sooner. Starting from next quarter, all quarterly status reports will be prepared the last month of the quarter itself, instead of the first month after the quarter's end. This means that deadlines for submitting reports will be the 1st of January, April, July and October. Next quarter will then be a short one, covering the months of November and December only and the report will probably be out in mid January. OpenBSD on Sparc64 (https://eerielinux.wordpress.com/2019/10/10/openbsd-on-sparc64-6-0-to-6-5/) OpenBSD, huh? Yes, I usually write about FreeBSD and that’s in fact what I tried installing on the machine first. But I ran into problems with it very early on (never even reached single user mode) and put it aside for later. Since I powered up the SunFire again last month, I needed an OS now and chose OpenBSD for the simple reason that I have it available. First I wanted to call this article simply “OpenBSD on SPARC” – but that would have been misleading since OpenBSD used to support 32-bit SPARC processors, too. The platform was just put to rest after the 5.9 release. Version 6.0 was the last release of OpenBSD that came on CD-ROM. When I bought it, I thought that I’d never use the SPARC CD. But here was the chance! While it is an obsolete release, it comes with the cryptographic signatures to verify the next release. So the plan is to start at 6.0 as I can trust the original CDs and then update to the latest release. This will also be an opportunity to recap on some of the things that changed over the various versions. News Roundup ZoL repo move to OpenZFS (https://zfsonlinux.topicbox.com/groups/zfs-discuss/T13eedc32607dab41/zol-repo-move-to-openzfs) Because it will contain the ZFS source code for both Linux and FreeBSD, we will rename the "ZFSonLinux" code repository to "OpenZFS". Specifically, the repo at http://github.com/ZFSonLinux/zfs will be moved to the OpenZFS organization, at http://github.com/OpenZFS/zfs. The next major release of ZFS for Linux and FreeBSD will be "OpenZFS 2.0", and is expected to ship in 2020. Mcclure111 Sun Thread (https://twitter.com/mcclure111/status/1196557401710837762) A long time ago— like 15 years ago— I worked at Sun Microsystems. The company was nearly dead at the time (it died a couple years later) because they didn't make anything that anyone wanted to buy anymore. So they had a lot of strange ideas about how they'd make their comeback. GEOM NOP (https://oshogbo.vexillium.org/blog/71/) Sometimes while testing file systems or applications you want to simulate some errors on the disk level. The first time I heard about this need was from Baptiste Daroussin during his presentation at AsiaBSDCon 2016. He mentioned how they had built a test lab with it. The same need was recently discussed during the PGCon 2019, to test a PostgreSQL instance. If you are FreeBSD user, I have great news for you: there is a GEOM provider which allows you to simulate a failing device. GNOP allows us to configure transparent providers from existing ones. The first interesting option of it is that we can slice the device into smaller pieces, thanks to the ‘offset option’ and ‘stripsesize’. This allows us to observe how the data on the disk is changing. Let’s assume that we want to observe the changes in the GPT table when the GPT flags are added or removed (for example the bootme flags which are described here). We can use dd every time and analyze it using absolute values from the disks. Keeping NetBSD up-to-date with pkg_comp 2.0 (https://jmmv.dev/2017/02/pkg_comp-2.0-tutorial-netbsd.html) This is a tutorial to guide you through the shiny new pkg_comp 2.0 on NetBSD. Goals: to use pkg_comp 2.0 to build a binary repository of all the packages you are interested in; to keep the repository fresh on a daily basis; and to use that repository with pkgin to maintain your NetBSD system up-to-date and secure. This tutorial is specifically targeted at NetBSD but should work on other platforms with some small changes. Expect, at the very least, a macOS-specific tutorial as soon as I create a pkg_comp standalone installer for that platform.

Друзья, рад представить вам интервью с Алексеем Лесовским и Виктором Егоровым из компании Data Egret (https://dataegret.ru/), записанное на прошедшей конференции Highload++ 2018 (http://www.highload.ru/moscow/2018). В этом выпуске мы говорим конечно же про Postgres. Не так давно у меня в гостях был Илья Космодемьянский, но мы больше говорили на общие темы баз данных, их роль в ИТ системах, образовании и прочем. В этот раз мы сконцентрировались больше на технических и практических аспектах работы с PostgreSQL. Мы обсудили типичные ошибки при проектировании база данных, которые допускают разработчики систем, обсудили типичные ошибки администраторов баз данных, углубились в различные технические аспекты работы PostgreSQL, такие как взаимодействие с дисками, Direct I/O и прочее. Подискутировали на тему кластеров, отказоустойчивости и безопасности систем, вспомнили различные вспомогательные инструменты для работы с PostgreSQL, такие как прокси-серверы, инструменты бэкап/рестора. В завершении выпуска обсудили последние нововведения в 11-й версии PostgreSQL и что может появится нового и интересного в 12-й версии базы данных.

This week, Allan is out of town, but since when has that ever stopped us from bringing you a new episode of BSDNow? We have news, This episode was brought to you by Headlines Unix's file durability problem (https://utcc.utoronto.ca/~cks/space/blog/unix/FileSyncProblem) Another article by Chris Siebenmann from the University of Toronto This time, the issue was a lost comment on his Python based blog which uses files on disk rather than a database After an unexpected restart of the system, a recently posted comment no longer existed The post goes on to investigate what the ‘right way' to ensure file durability is The answer, as you might expect, is “it depends…” Normally, fsync() should work, but it seems with ext4 and some other file systems, you must also fsync() the directory where the file was created, or it might not be possible to find the file after a crash Do you need to fsync() the parent of that directory too? Then what is fdatasync() for? What about just calling sync()? “One issue is that unlike many other Unix API issues, it's impossible to test to see if you got it all correct and complete. If your steps are incomplete, you don't get any errors; your data is just silently sometimes at risk. Even with a test setup to create system crashes or abrupt power loss (which VMs make much easier), you need uncommon instrumentation to know things like if your OS actually issued disk flushes or just did normal buffered writes. And straightforward testing can't tell you if what you're doing will work all the time, because what is required varies by Unix, kernel version, and the specific filesystem involved.” Second post by author: How I'm trying to do durable disk writes (https://utcc.utoronto.ca/~cks/space/blog/python/HowISyncDataDWiki) Additional Discussion on Hacker News (https://news.ycombinator.com/item?id=11511269) The discussion on HN also gets into AIO and other more complicated facilities, but even those seem to be vague about when your data is actually safe At least ZFS ensures you never get half of your new data, and half of your old data. *** Build a FreeBSD 10.3-release Openstack Image with bsd-cloudinit (https://raymii.org/s/tutorials/FreeBSD_10.3-release_Openstack_Image.html) Are you using FreeBSD and OpenStack or would you like to be? We next have a great tutorial which explains the ins-and-outs of doing exactly that. Remy van Elst brings us a great walkthrough on his site on how to get started, and hint it involves just a few ‘pip' commands. After getting the initial Python tools bootstrapped, next he shows us how to save our OpenStack settings in a sourceable shell command, which comes in handy before doing admin on a instance. Next the ‘glance' and ‘cinder' tools are used to upload the target OS ISO file and then create a volume for it to install onto. Next the VM is started and some specific steps are outlined on getting FreeBSD 10.3 installed into the instance. It includes some helpful hints as how to fix a mountroot error, if you installed to ada0, but need to mount via vtdb0 instead now. After the installation is finished, the prep for ‘cloudinit' is done, and the resulting image is compressed and made ready for deployment. We've kinda stepped through some of the more gory steps here, but if OpenStack is something you work with, this tutorial should be at the top of your “must read” list. *** Undeadly and HTTPS (http://undeadly.org/cgi?action=article&sid=20160411201504) Undeadly, the OpenBSD journal, is thinking of moving to HTTPS only In order to do this, they would like some help rewriting part of the site Currently, when you login to post comments, this is done over HTTPS, but to an stunnel instance running a custom script that gives you a cookie, and sends you back to the non-HTTPS site They would like to better integrate the authentication system, and otherwise improve the code for the site There is some pushback as well, questioning whether it makes sense to block users who are unable to use HTTPS for one reason or another I think it makes sense to have the site default to HTTPS, but, maybe HTTPS only doesn't make sense. There is nothing private on the site, other than the authentication system which is optional, not required to post a comment. There is also some discussion about the code for the site, including the fact that when the code was released, the salt for the password database was included This is not actually a security problem, but the discussion may be interesting to some viewers *** FreeBSD Journal March/April Edition (https://www.freebsdfoundation.org/journal/browser-based-edition/) The next issue of the FreeBSD Journal is here, and this time it is about Teaching with Operating Systems In addition to the usual columns, including: svn update, the ports report, a conference report from FOSDEM, a meetup report from PortsCamp Taipei, A book review of "The Algorithm Design Manual", and the Events Calendar; there are a set of feature articles about teaching Teaching with FreeBSD through Tracing, Analysis, and Experimentation CHERI: Building a foundation for secure, trusted computing bases A brief history of Fast Filesystems There is also an interview with Gleb Smirnoff, a member of the Core team, release engineering, and the deputy security officer, as well as a senior software developer at Netflix Get the latest issue from your favourite mobile store, or the “Desktop Edition” directly in your browser from the FreeBSD Foundation's website *** Interview - Brooks Davis - brooks@FreeBSD.org (mailto:brooks@FreeBSD.org) / @brooksdavis (https://twitter.com/brooksdavis) CHERI and Capabilities *** TrueNAS Three-Peats!!! (https://www.ixsystems.com/blog/truenas-three-peats/) News Roundup UbuntuBSD Is Looking To Become An Official Ubuntu Flavor (http://linux.softpedia.com/blog/ubuntubsd-is-looking-to-become-an-official-ubuntu-flavor-502746.shtml) You may recall a few weeks back that we were a bit surprised by the UbuntuBSD project and its longevity / goals. However the project seems to be pushing forward, with news on softpedia.com that they are now seeking to become an ‘official' Ubuntu Flavor. They've already released a forth beta, so it seems the project currently has some developers pushing it forward: "I would like to contribute all my work to Ubuntu Community and, if you think it is worthy, make ubuntuBSD an official Ubuntu project like Xubuntu or Edubuntu," said Jon Boden. "If you're interested, please let me know how would you like me to proceed." It's Just Bits (http://blog.appliedcompscilab.com/its_just_bits/index.html) We have next an interesting blog post talking about the idea that “It's just all bits!” The author then takes us down the idea of no matter how old or mysterious the code may be, in the end it is ending up as bits arranged a certain way. Then the article transitions and takes us through the idea that old bits, and bits that have grown too large should often be good candidates for replacement by “simpler” bits, using OpenBSD as an example. “The OpenBSD community exemplifies this in many ways by taking existing solutions and simplifying them. Processing man pages is as old as Unix, and even in the 21st century OpenBSD has taken the time to rewrite the existing solution to be simpler and safer. It's just bits that need to be turned into other bits. Similarly, OpenBSD has introduced doas as an alternative to sudo. While not replacing sudo entirely, doas makes the 99.99% case of what people use sudo for easier and safer. They are just bits that need to be authenticated. “ All in all, a good read, and it reinforces the point that nothing is really truly “finished”. As computing advances and new technologies / practices are made available, sometimes it makes a lot of sense to go back and re-write things in order to simplify the complexity that has snuck in over time. *** Disk IO limiting is coming to FreeBSD (https://lists.freebsd.org/pipermail/svn-src-head/2016-April/084288.html) A much requested feature for both Jails and VM's on FreeBSD has just landed with experimental support in -HEAD, Disk IO limiting! The Commit message states as follows: “Add four new RCTL resources - readbps, readiops, writebps and writeiops, for limiting disk (actually filesystem) IO. Note that in some cases these limits are not quite precise. It's ok, as long as it's within some reasonable bounds. Testing - and review of the code, in particular the VFS and VM parts - is very welcome.” Well, what are you waiting for? This is a fantastic new feature which I'm sure will get incorporated into other tools for controlling jails and VM's down the road. If you give it a spin, be sure to report back bugs so they can get quashed in time for 11. *** BeastieBits PC-BSD 10.3 Is the Last in the Series, PC-BSD 11.0 Arrives Later This Year (http://news.softpedia.com/news/pc-bsd-10-3-is-the-last-in-the-series-pc-bsd-11-0-arrives-later-this-year-502570.shtml) ASLR now on by default in NetBSD amd64 (http://mail-index.netbsd.org/source-changes/2016/04/10/msg073939.html) Daniel Bilik's fix for hangs on Baytrail (http://lists.dragonflybsd.org/pipermail/users/2016-April/228682.html) Don't forget about PGCon 2016 (http://www.pgcon.org/2016/) Get your paper in for EuroBSDCon 2016, deadline is May 8th (https://2016.eurobsdcon.org/call-for-papers/) Feedback/Questions John - Destroy all Dataset (http://pastebin.com/QdGWn0TW) Thomas - Misc Questions (http://pastebin.com/43YkwBjP) Ben - ZFS Copy (http://pastebin.com/gdi3pswe) Bryson - SysV IPC (http://pastebin.com/E9n938D1) Drin - IPSEC (http://pastebin.com/bgGTmbDG) ***

When standards exist (such as ANSI Standard C) stick to them. Even after you have adopted a strategy, you should nevertheless reexamine it from time to time. Keep focused on your real goal, Einstein was right: Things should be as simple as possible but not simpler. *** pfSense 2.3 released (https://blog.pfsense.org/?p=2008) Rewrite of the webGUI utilizing Bootstrap TLS v1.0 disabled for the GUI Moved to a FreeBSD 10.3-RELEASE base PHP Upgraded to 5.6 The "Full Backup" feature has been deprecated Closed 760 total tickets of which 137 are fixed bugs Known Regressions OpenVPN topology change IP aliases with CARP IP parent lose their parent interface association post-upgrade IPsec IPComp does not work.

The idea came about due to his working on multi-platform software, and the frustrations of dealing with POSIX violations The crux of the post is how he deals with these workarounds. Specifically by only applying them to the particular system in which it was required. And doing so loudly. This has some important benefits. First, it doesn't potentially expose other systems to bugs / security flaws when a workaround doesn't “work” on a system for which it wasn't designed. Secondly it's important to complain. Loudly. This lets the user know that they are running on a system that doesn't adhere to POSIX compliance, and maybe even get the attention of a developer who could remedy the situation. *** Privilege escalation in calendar(1) (http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2016-003.txt.asc) File this one under “Ouch that hurts” a new security vuln has been posted, this time against NetBSD's ‘calendar' command. Specifically it looks like some of the daily scripts uses the ‘-a' flag, which requires super-user privs in order to process all users calendar files and mail the results. However the bug occurred because the calendar command didn't drop priv properly before executing external commands (whoops!) To workaround you can set run_calendar=NO in the daily.conf file, or apply the fixed binary from upstream. *** PGCon 2016 (http://www.pgcon.org/2016/) PGCon 2016 is now only 4 weeks away The conference will be held at the University of Ottawa (same venue as BSDCan) from May 17th to 20th Tutorials: 17-18 May 2016 (Tue & Wed) Talks: 19-20 May 2016 (Thu-Fri) Wednesday is a developer unconference. Saturday is a user unconference. “PGCon is an annual conference for users and developers of PostgreSQL, a leading relational database, which just happens to be open source. PGCon is the place to meet, discuss, build relationships, learn valuable insights, and generally chat about the work you are doing with PostgreSQL. If you want to learn why so many people are moving to PostgreSQL, PGCon will be the place to find out why. Whether you are a casual user or you've been working with PostgreSQL for years, PGCon will have something for you.” New to PGSQL? Just a user? Long time developers? This conference has something for you. A great lineup of talks (https://www.pgcon.org/2016/schedule/events.en.html), plus unconference days focused on both users and developers *** CfP EuroBSDCon 2016 (https://2016.eurobsdcon.org/call-for-papers/) The call for papers has been issued for EuroBSDCon 2016 in Belgrade, Serbia The conference will be held from the 22nd to 25th of September, 2016 The deadline for talk submissions is: Sunday the 8th of May, 2016 Submit your talk or tutorial proposal before it is too late *** Beastie Bits “FreeBSD Mastery: Advanced ZFS” has officially been released (https://www.michaelwlucas.com/nonfiction/fmaz) Support of OpenBSD pledge(2) in programming Languages (https://gist.github.com/ligurio/f6114bd1df371047dd80ea9b8a55c104) pkgsrcCon 2016 -Call for Presentations (http://daemonforums.org/showthread.php?t=9781) Christos Zoulas talks about blacklistd (http://blog.netbsd.org/tnf/entry/talks_about_blacklistd) Penguicon 2016 Lucas Track Schedule (http://blather.michaelwlucas.com/archives/2617) Feedback/Questions Peter - NVME (http://pastebin.com/HiiDpGcT) Jeremy - Wireless Gear (http://pastebin.com/L5XeVS1H) Ted - Rpi2 Packages (http://pastebin.com/yrCEnkWt) - Cross Building Wiki (https://wiki.freebsd.org/FreeBSD/arm/crossbuild) Geoff - Jail Failover (http://pastebin.com/pYFC1vdQ) Zach - Graphical Bhyve?
