Users of OpenSMTPd can rejoice in having no work to do; others will have to install sendmail from packages.

2Q Buffer Cache in OpenBSD

Ted Unangst (tedu@) wrote a blog post about his replacement of the simple LRU buffer cache algorithm with a 2Q-ish one: Since the dawn of time, the OpenBSD buffer cache replacement algorithm has been LRU. It’s not always ideal, but it often comes close enough and it’s simple enough to implement that it’s remained the tried and true classic for a long time. I just changed the algorithm to one modelled somewhat after the 2Q algorithm by Johnson and Shasha. (PDF) Read more...

Persist tmux environment across system restarts

cs, 2014-09-04 10:00
Nagy Gábor writes in with a tip:
Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects.

PF Tutorial Rolls Past 200,000 Unique Visitors

sze, 2014-06-18 12:09
As you may have heard via Twitter, the PF tutorial by Peter N. M. Hansteen -- a BSD conferences favorite and the predecessor of The Book of PF (with the third edition soon to be in "early access" availability) -- just saw its 200,000th unique visitor and has had somewhat in excess of 3 million page views.

Author Peter Hansteen comments, "It's good to see that the thing is still widely read and referenced. I'll keep working on that and the book for as long at is makes sense.", and continues, "But please do remember that I would have had noting to write about without a vital OpenBSD project producing high quality stuff. Please remember to not just buy the book, but also donate to the project to help keep it running."

You heard the man, now go ahead, read and donate!

OpenSSL Releases Bugfixes, Advance Notice To Some Vendors But Not OpenBSD

Earlier today the OpenSSL project released multiple upgrade versions with fixes for several recently reported bugs in their code base.

The most noteworthy thing is not that the OpenSSL project fixes bugs, but rather that information about the bugs had been privately communicated to a list of vendors that did not include OpenBSD. A seclist discussion reveals the full timeline, while the OpenBSD community's reaction can be gauged by this thread on misc@.

sendmail(8) Patch In -stable Fixes Local Snooping Vulnerability

cs, 2014-06-05 17:54
For those of you who are still using sendmail(8) on OpenBSD 5.4 or 5.5, it's patch and update time.

The vulnerability known as CVE-2014-3956 could allow local users to interfere with open SMTP connections, and it is strongly advised that any sendmail users out there patch their systems without undue delay.

Patches are available for OpenBSD 5.4 and OpenBSD 5.5 as patch 011 and patch 007 respectively.

It is worth noting that from OpenBSD 5.6 onwards (to be released November 1st, 2014), OpenSD's own OpenSMTPD will be the default MTA.

ld.so has a very basic malloc. This diff changes it to use a (somewhat stripped) libc malloc with all the randomization and other goodness. Read more...
