Felix Palmen :freebsd: :c64:

First change since #swad 0.2 will actually be a (huge?) improvement to my #poser lib. So far, it was hardwired to use the good old #POSIX #select call. This is perfectly fine for handling around up to 100 (or at least less than 1000, YMMV) clients.

Some #select implementations offer defining the upper limit for checked file descriptors. Added support for that.

POSIX also specifies #poll, which has very similar #scalability issues, but slightly different. Added support for this as well.

And then, I went on to add support for the #Linux-specific #epoll and #BSD-specific #kqueue (#FreeBSD, #NetBSD, #OpenBSD, ...) which are both designed to *solve* any scalability issues 🥳

A little thing that slightly annoyed me about kqueue was that there's no support for temporarily changing the signal mask, so I had to do the silly dance shown in the screenshot. OTOH, it offers changing event filters and getting events in a single call, which I might try to even further optimize ... 😎

kqueue client code, manually relaxing the signal mask for just the single kevent() call waiting for new events.

events.bsdnl.nlA packet's journey through pf BSD-NL Conference - Early 2025A walkthrough of a packet's journey through (FreeBSD's) pf, concentrating on the big picture and its implications. We'll cover when packets are inspected, when rules are evaluated and how states are used. Along the way we'll cover what DTrace probes can show us, what some of pfctl's counters mean and just how many times pf can look at a single packet. This talk is intended for firewall admins looking for a deeper understanding and aspiring pf developers. It is not a "How to use pf" talk.
