This week on BSD Now, we review the EuroBSDcon schedule, we explore the mysteries of Docker on OpenBSD, and show you how to run PostgreSQL on ZFS. This episode was brought to you by Headlines EuroBSDcon 2017 - Talks & Schedule published (https://2017.eurobsdcon.org/2017/05/26/talks-schedule-published/) The EuroBSDcon website was updated with the tutorial and talk schedule for the upcoming September conference in Paris, France. Tutorials on the 1st day: Kirk McKusick - An Introduction to the FreeBSD Open-Source Operating System, George Neville-Neil - DTrace for Developers, Taylor R Campbell - How to untangle your threads from a giant lock in a multiprocessor system Tutorials on the 2nd day: Kirk continues his Introduction lecture, Michael Lucas - Core concepts of ZFS (half day), Benedict Reuschling - Managing BSD systems with Ansible (half day), Peter Hessler - BGP for developers and sysadmins Talks include 3 keynotes (2 on the first day, beginning and end), another one at the end of the second day by Brendan

A pledge of love to OpenBSD, combating ransomware like WannaCry with OpenZFS, and using PFsense to maximize your non-gigabit Internet connection This episode was brought to you by Headlines ino64 project committed to FreeBSD 12-CURRENT (https://svnweb.freebsd.org/base?view=revision&revision=318736) The ino64 project has been completed and merged into FreeBSD 12-CURRENT Extend the inot, devt, nlinkt types to 64-bit ints. Modify struct dirent layout to add doff, increase the size of dfileno to 64-bits, increase the size of dnamlen to 16-bits, and change the required alignment. Increase struct statfs fmntfromname[] and fmntonname[] array length MNAMELEN to 1024 This means the length of a mount point (MNAMELEN) has been increased from 88 byte to 1024 bytes. This allows longer ZFS dataset names and more nesting, and generally improves the usefulness of nested jails It also allow more than 4 billion files to be stored in a single file system (both UFS and ZFS). It also deals with a number of NFS problems, such a

This week on BSD Now we cover the latest FreeBSD Status Report, a plan for Open Source software development, centrally managing bhyve with Ansible, libvirt, and pkg-ssh, and a whole lot more. This episode was brought to you by Headlines FreeBSD Project Status Report (January to March 2017) (https://www.freebsd.org/news/status/report-2017-01-2017-03.html) While a few of these projects indicate they are a "plan B" or an "attempt III", many are still hewing to their original plans, and all have produced impressive results. Please enjoy this vibrant collection of reports, covering the first quarter of 2017. The quarterly report opens with notes from Core, The FreeBSD Foundation, the Ports team, and Release Engineering On the project front, the Ceph on FreeBSD project had made considerable advances, and is now usable as the net/ceph-devel port via the ceph-fuse module. Eventually they hope to have a kernel RADOS block device driver, so fuse is not required CloudABI update, including news that the Bitcoin referenc

This week on BSD Now, Adrian Chadd on bringing up 802.11ac in FreeBSD, a PFsense and OpenVPN tutorial, and we talk about an interesting ZFS storage pool checkpoint project. This episode was brought to you by Headlines Bringing up 802.11ac on FreeBSD (http://adrianchadd.blogspot.com/2017/04/bringing-up-80211ac-on-freebsd.html) Adrian Chadd has a new blog post about his work to bring 802.11ac support to FreeBSD 802.11ac allows for speeds up to 500mbps and total bandwidth into multiple gigabits The FreeBSD net80211 stack has reasonably good 802.11n support, but no 802.11ac support. I decided a while ago to start adding basic 802.11ac support. It was a good exercise in figuring out what the minimum set of required features are and another excuse to go find some of the broken corner cases in net80211 that needed addressing. 802.11ac introduces a few new concepts that the stack needs to understand. I decided to use the QCA 802.11ac parts because (a) I know the firmware and general chip stuff from the first generat

This week we have a FreeBSD Foundation development update, tell you about sprinkling in the TrueOS project, Dynamic WDS & a whole lot more! This episode was brought to you by Headlines OpenSSH Removes SSHv1 Support (http://undeadly.org/cgi?action=article&sid=20170501005206) In a series of commits starting here (http://marc.info/?l=openbsd-cvs&m=149359384905651&w=2) and ending with this one (http://marc.info/?l=openbsd-cvs&m=149359530105864&w=2), Damien Miller completed the removal of all support for the now-historic SSHv1 protocol from OpenSSH (https://www.openssh.com/). The final commit message, for the commit that removes the SSHv1 related regression tests, reads: Eliminate explicit specification of protocol in tests and loops over protocol. We only support SSHv2 now. Dropping support for SSHv1 and associated ciphers that were either suspected to or known to be broken has been planned for several releases, and has been eagerly anticipated by many in the OpenBSD camp. In practical terms this means that star

Today on BSD Now, the latest Dragonfly BSD release, RaidZ performance, another OpenSSL Vulnerability, and more; all this week on BSD Now. This episode was brought to you by Headlines DragonFly BSD 4.8 is released (https://www.dragonflybsd.org/release48/) Improved kernel performance This release further localizes cache lines and reduces/removes cache ping-ponging on globals. For bulk builds on many-cores or multi-socket systems, we have around a 5% improvement, and certain subsystems such as namecache lookups and exec()s see massive focused improvements. See the corresponding mailing list post with details. Support for eMMC booting, and mobile and high-performance PCIe SSDs This kernel release includes support for eMMC storage as the boot device. We also sport a brand new SMP-friendly, high-performance NVMe SSD driver (PCIe SSD storage). Initial device test results are available.

Stay This episode was brought to you by Headlines OpenBSD changes of note 6 (http://www.tedunangst.com/flak/post/openbsd-changes-of-note-6) OpenBSD can now be cross built with clang. Work on this continues Build ld.so with -fno-builtin because otherwise clang would optimize the local versions of functions like dlmemset into a call to memset, which doesn’t exist. Add connection timeout for ftp (http). Mostly for the installer so it can error out and try something else. Complete https support for the installer. I wonder how they handle certificate verification. I need to look into this as I’d like to switch the FreeBSD installer to this as well New ocspcheck utility to validate a certificate against its ocsp responder. net lock here, net lock there, net lock not quite everywhere but more than before.

This week on BSDNow, we’re going to be leading off with the latest news about Wayland and Xorg support on FreeBSD, then a look at OpenBSD ARM64 This episode was brought to you by Headlines Wayland is now in the FreeBSD Ports tree (https://svnweb.freebsd.org/ports?view=revision&revision=432406) This commit brings Wayland, the new windowing system, into the FreeBSD ports tree “This port was first created by Koop Mast (kwm@) then updated and improved by Johannes Lundberg” “Wayland is intended as a simpler replacement for X, easier to develop and maintain. GNOME and KDE are expected to be ported to it.” Wayland is designed for desktop and laptop use, rather than X, which was designed for use over the network, where clients were not powerful enough to run the applications locally. “Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X a

This week on BSD Now, we will be discussing a wide variety of topics including Routers, Run-Controls, the “Rule” of silence and some This episode was brought to you by Headlines Ports no longer build on EOL FreeBSD versions (https://www.reddit.com/r/freebsd/comments/5ouvmp/ports_no_longer_build_on_eol_freebsd_versions/) The FreeBSD ports tree has been updated to automatically fail if you try to compile ports on EOL versions of FreeBSD (any version of 9.x or earlier, 10.0 - 10.2, or 11 from before 11.0) This is to prevent shooting yourself in the food, as the compatibility code for those older OSes has been removed now that they are no longer supported. If you use pkg, you will also run into problems on old releases. Packages are always built on the oldest supported release in a branch. Until recently, this meant packages for 10.1, 10.2, and 10.3 were compiled on 10.1. Now that 10.1 and 10.2 are EOL, packages for 10.x are compiled on 10.3. This matters because 10.3 supports the new openat() and various other
