Kristaps Dzonsons on pledge(2)

szo, 2016-11-26 04:28

Kristaps Dzonsons, of mandoc and acme-client (and more) fame, has written a detailed article entitled "why pledge(2) …or, how I learned to love web application sandboxing".

The tl;dr section starts:

For practical web applications, pledge(2) presents the best compromise of development simplicity and security coverage. This alone gives BCHS applications even more of a boost beyond the many other advantages of programming on OpenBSD.

The article discusses the advantages of pledge(2) over other sandboxing systems.

    vmm enabled

    sze, 2016-10-12 09:57
    With a small commit, OpenBSD now has a hypervisor and virtualization in-tree. This has been a lot of hard work by Mike Larkin, Reyk Flöter, and many others.

    VMM requires certain hardware features (Intel Nehalem or later, and virtualization enabled in the BIOS) in order to provide VM services, and currently only supports OpenBSD guests.

    CVSROOT: /cvs Module name: src Changes by: 2016/10/12 02:30:26 Modified files: sys/arch/amd64/conf: GENERIC Log message: enable vmm

    This has been enabled in snapshots for a week, so your favourite mirror is already ready for you to upgrade. Of course, please report any bugs you run into.

    This work was partially sponsored by The OpenBSD Foundation, and if you like it, please donate or bid on the signed cd set.

    g2k16 Hackathon Report: Alexander Bluhm on mbufs and more

    szo, 2016-09-17 13:18

    Alexander Bluhm (bluhm@) contributed our next report (which even includes a picture):

    Big plans what to do at a hackathon don't work. There is always something unexpected that requires your attention. So I was expecting the unexpected. The TCP send performance has dropped to a very low throughput in some environments. It was pretty clear that it was related with claudio@'s change to speed up TCP by using large mbufs instead of chaining small ones. Mbufs are used inside the kernel to hold network data. Using a lot of them requires many allocations and frees. This can be avoided by using larger mbufs. But why did it get slower? Together with mikeb@ we found out that it was related to the mbuf space limit in the socket buffer. One large mbuf filled the send buffer, so no new mbufs could be inserted until TCP received the acknowledgements for everything. So the sliding window algorithm with mbufs cycling through the socket buffer did not work anymore. After identifying the problem, the fix was easy, just increase the default socket buffer mbuf size limit.

    Ted Unangst (tedu@) has written an item regarding doas:

    It’s been a year since the introduction of doas, so it’s clearly time to write a book. Or maybe a pamphlet.

    One of the first things to do when attending a hackathon is travel planning.

    Shortly before the hackathon I contacted mpi@ to check up on the status of his Dynamic Profiling (read DTrace) work. This eventually led me to my goal for this hackathon of making a start integrating CTF into our kernel.
