Sometime in the last week OpenBSD crossed 400,000 commits (*) upon all our repositories since starting at 1995/10/18 08:37:01 Canada/Mountain. That's a lot of commits by a lot of amazing people.

Everyone thinks the best way to help with OpenBSD ports, is to find something you use that hasn't been ported and create a port of it. This talk will discuss this and other misconceptions, how best to actually help OpenBSD porters with their work, and tips for how to get one's work noticed on the OpenBSD ports lists. The talk will contain examples of good submissions and counterexamples likely to get ignored (these will be made up, I will not be singling out people).

CVE-2019-8460.

Reuven Plevinsky and Tal Vainshtein of Check Point Software Technologies Ltd. discovered that OpenBSD kernel (all versions, including 6.5) can be forced to create long chains of TCP SACK holes that cause very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service.
