This weekend is the perfect time to get your #eurobsdcon submissions done!

The Call for papers https://2026.eurobsdcon.org/cfp/ is open until June 20th, for the conference in Brussels September 9-13, 2026.

We also offer pre-submission guidance/mentoring, see towards the end of the CFP document.

so it cost anthropic $20k to find this openbsd crash bug which amounts to putting a negative integer in a tcp field where a negative integer was not expected by the c code which does some cavalier int cast bullshit, ie. a vuln which is totally fuzzable, and quite certainly would have been found by the fuzzers of the 2010s had anyone cared to burn that much compute on fuzzing openbsd.

The difference today is not that anybody suddenly cares about investing that much in openbsd (is the build server still a donated machine running in Theo's basement?), but that openbsd's reputation for security makes it really good marketing if you can find a bug, any bug, it doesn't matter; and that marketing value is what makes it worth spending $20k on fuzzing.

Does computer #history interest you, or maybe you're just curious where well-known and well-used tools come from? I've just updated the History of #Unix #Manpages, https://manpages.bsd.lv/history.html, with the content you didn't know you wanted til this very moment. Learn about how the "man" program came to be, and just why are manpages styled like that? It includes snippets from Cynthia "Cindy" Livingston, who wrote the manpage language "mdoc"; John Eaton, who wrote the first GPL man tool; Doug McIlroy, who helped to divide manpages into sections; and more. Did you know that serving manpages online was part of one of the original http daemons? Or that an xman existed before X11R6, in X10? Enjoy!

Kirill A. Korinsky (kirill@) has added 160MHz channel width support (5GHz) to #OpenBSD's net80211 wireless stack, with the first driver receiving support being iwx(4) for Intel WiFi 6/6E devices. β€‹

PF queues break the 4 Gbps barrier

OpenBSD's PF packet filter has long supported HFSC traffic shaping with the queue rules in pf.conf(5). However, an internal 32-bit limitation in the HFSC service curve structure (struct hfsc_sc) meant that bandwidth values were silently capped at approximately 4.29 Gbps, ” the maximum value of a u_int ".
