Review: Guarding the gates with OpenBSD 5.8

• Jesse Smith over at DistroWatch treats us this week to a nice review of OpenBSD 5.8, which may be a good introduction for the uninitiated to learn more+ He first walks through some of the various highlights of 5.8, and spends time introducing the reader to a number of the projects that originate from OpenBSD, such as LibreSSL, OpenSSH, doas, the new “file” implementation and W^X support on i386.
• The article then walks through his impressions of performing a fresh install of 5.8, and then getting up and running in X.
• He mentions that you may want to check the installation defaults, since on his 8GB VM disk, it didn’t leave enough room for packages on the /usr partition.
• It also includes a nice heads-up for new users about using the pkg_add command, and where / how you can set the initial repository mirror address.
• The “doas” command was also praised:“I found I very much appreciated the doas command, its documentation and configuration file. The doas configuration file is much easier to read than sudo's and the available options are well explained. The doas command allowed me to assign root access to a user given the proper password and doas worked as advertised.”
• A glowing summary as well:“OpenBSD may be very secure, but I think what sets the operating system apart are its documentation and clean system design. It is so easy to find things and understand the configuration of an OpenBSD system. The file system is organized in a clean and orderly manner. It always takes me a while to get accustomed to using OpenBSD, as for me it is a rare occurrence, but once I get settled in I like how straight forward everything is. I can usually find and configure anything on the system without referring to external documents or searching for answers on-line and that is quite an accomplishment for an operating system where virtually everything is done from the command line. “ ***

OpenBSD Hackathon Reports

• Alexander Bluhm: multiprocessor networking
• “The next step, we are currently working on, is to remove the big kernel lock from forwarding and routing. mpi@ has been doing this for a long time, but some corner cases were still left. I have written a regression test for handling ARP packets to show that all cases including proxy ARP are still working. Another thing that may happen with lock-free routing is that the interface is destroyed on one CPU while another CPU is working with a route to that interface. We finally got this resolved. The code that destroys the interface has to wait until all routes don't use this interface anymore. I moved the sleep before the destruction of the interface is started, so that the routes can always operate on a completely valid interface structure.”
