Hackfest OpenBSD presentations

h, 2015-11-23 17:16
Two OpenBSD developers gave presentations at this year's Hackfest security conference in Quebec. The videos of both are now online for your viewing pleasure:

  • "Kernel W^X Improvements In OpenBSD" by Mike Larkin (mlarkin@) (slides)
  • "Pledge: A New Security Technology in OpenBSD" by Theo de Raadt (deraadt@) (slides)
  • Kategóriák: *BSD

    Interview: Renato Westphal (renato@)

    h, 2015-11-23 12:13
    Renato Westphal (renato@) recently agreed to answer some questions in the wake of committing eigrpd(8): First off, thanks for agreeing to this interview. Tell us a little about yourself, your technical background, and how you came to the OpenBSD project. My name is Renato Westphal and I was born and live in the south of Brazil. Currently I work for Taghos Tecnologia developing web cache and CDN solutions and in my previous job I worked for a small network equipment manufacturer, which is where my background in routing protocols comes from.

    vmm(4) userland bits vmd(8), vmmctl(8) hit -current

    v, 2015-11-22 22:38
    The long-anticipated native OpenBSD amd64 and i386 hypervisor vmm(4) has been committed, with userland tools, to the public CVS repository. If you've been following source changes closely, you probably noticed the series of commits like this one from Mike Larkin (mlarkin@), supplemented with one by Reyk Floeter (reyk@). In an announcement and overview sent to tech@, Mike writes:

    An early rough cut of the vmm subsystem is now in the tree. This includes both the kernel parts and userland parts.

    u2k15: mikeb@ on IPSEC progress (Chacha20-Poly1305)

    sze, 2015-11-18 15:14
    In our ongoing series of ü2k15 hackathon reports, here is Mike Belopuhov's (mikeb@) entry:

    My task at ü2k15 was to implement Chacha20-Poly1305 authenticated encryption mode for use in the IPsec stack within the Encapsulating Security Payload (ESP) protocol.

    The Authenticated Encryption with Associated Data (AEAD) construction for Chacha20 stream cipher and Poly1305 polynomial Message Authentication Code (MAC) is described in the RFC7539 and its application in IPsec/ESP can be found in RFC7634.

    u2k15: florian@ on IPv6 hackery

    h, 2015-11-16 22:44
    The next hackathon report is from Florian Obser (florian@), who writes:

    I'm not entirely sure if mg(1) has dedicated maintainers, but if there are it's probably lum@, jasper@ and me. When u2k15 was first discussed at c2k15 in Calgary someone said: "Florian, will you come? We need utf8 for mg!" Me: "For sure I will come, I will build myself an IT throne and mock anybody who touches mg(1)'s input handling." Read more...

    Status of pledge(2)

    h, 2015-11-16 05:39
    For those wondering about the ongoing integration progress of OpenBSD's pledge(2) subsystem, Theo de Raadt (deraadt@) has an informative update.

    Our base system contains 600 ELF binaries, which are found in the directories /bin /sbin /usr/bin /usr/sbin and /usr/libexec. 368 have been converted to use pledge in some form -- generally the application of pledge is quite strong. This is that list: Read more...

    u2k15: stsp@ on hackathon shirts, setup, UTF-8 and more

    p, 2015-11-13 15:58
    Our next u2k15 hackathon report comes from none other than Stefan Sperling (stsp@), who writes:

    OpenBSD hackathons without travel are pretty weird. Taking the train or bus to the hackroom in 30 minutes from home was quite a change from the usual 24+ hour trips around the planet. Instead of travelling I spent some time organising things, but nearly not as much as I expected. Read more...

    Initial 802.11n wireless support for iwm(4)

    cs, 2015-11-12 22:27
    Stefan Sperling (stsp@) writes in to the tech@ list with a great announcement for WiFi users:

    This diff adds an initial implementation of 802.11n. It is functional but mostly adds foundations to build future work on top of. It completes the little bits of 11n code added by damien@ years ago. It supports all non-optional 11n features for STA (client) operation. Read more...

    u2k15: sebastia@ on packages progress

    h, 2015-11-09 21:24
    The next u2k15 hackathon report comes from Sebastian Reitenbach (sebastia@), with adventures from packages land:

    With my rare spare time, I took the chance to attend a hackathon nearby. Even I haven't had much business dealing with ümlauts and other odd characters, I had enough on my list to keep me busy.

    u2k15: jung@ on asmc(4), ports work, EFI testing

    h, 2015-11-09 20:22
    The next report from the 2k15 hackathon comes from Joerg Jung (jung@), chronicling among other things the introduction of asmc(4):

    Arriving at u2k15 I had a rather large refactoring patch for asmc(4) in my tree, which required some more tests. After finishing these I committed the changes, which fixed timing issues avoiding excessive tsleep()s and also fixed some 'comm collsion' errors. Moreover, I enabled asmc(4) on i386 as I received positive test reports for older Apple hardware (thanks to kettenis@).

    u2k15: mpi@ on network SMPization cleanup

    h, 2015-11-09 15:42
    Our next u2k15 report comes from Martin Pieuchot (mpi@):

    As expected I did not do any UTF-8 related task during u2k15... Instead I sat in the network^Wfunky room to continue working on unlocking the network stack.

    OpenBGPd and route filters

    szo, 2015-11-07 00:05
    Many moons ago, OpenBGPd was extensively used throughout the networking world as a Route Server. However, over the years, many have stopped using it and have migrated away to other implementations. Recently, I have been getting more involved with the networking community, so I decided to ask "why?" Read more...

    u2k15: krw@ on msdosfs fixes, installer cleanup, GPT fdisk, softraid, dhclient

    v, 2015-11-01 19:41
    The first report to come in from the newly completed u2k15 hackathon in Berlin is from Ken Westerback (krw@), who writes:

    After a roundabout trip via Warsaw and Zurich I arrived in Berlin late on the 22nd, made a brief appearance at the hackroom to ensure I still knew the way (beware the non-euclidean nature of roads in Berlin!), and then slept the sleep of the traveller to be fresh for hacking.

    OpenBSD 5.8 released

    v, 2015-10-18 15:45
    October 18th, 2015: The OpenBSD team marks the 20th anniversary of the project today with the general availability of OpenBSD 5.8.

    We are pleased to announce the official release of OpenBSD 5.8. This is our 38th release on CD-ROM (and 39th via FTP/HTTP). We remain proud of OpenBSD's record of twenty years with only two remote holes in the default install. As in our previous releases, 5.8 provides significant improvements, including new features, in nearly all areas of the system: Read more...
