Bryan Steele :flan_beard:<p>David Gwynne (dlg@) has imported a new daemon to <a href="https://bsd.network/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenBSD</span></a> -current, not yet linked to the build.</p><p>lldpd(8), a new LLDP (Link Layer Discovery Protocol) agent daemon.</p><p>This daemon uses the newly added AF_FRAME socket protocol type.</p><blockquote><p>dlg@ modified src/usr.sbin/lldpd/*: lldpd(8): a daemon that acts as an LLDP agent on Ethernet interfaces.</p><p>lldpd uses the recently added AF_FRAME Ethernet sockets to listen for LLDP packets on all Ethernet interfaces in the system, and stores them so a lldp(8) client connecting to the control socket can fetch and display the packets.</p><p>AF_FRAME means we can avoid BPF for receiving LLDP packets, which has a couple of benefits.</p><p>firstly, BPF needs to look at all packets entering an interface so it can filter for the ones you're interested in, which is annoying for low packet/data rate protocols like LLDP. AF_FRAME is handled late in ether_input, and only after other protocols (like ip) are handled, so it's lower overhad compared to BPF listeners.</p><p>secondly, attaching a BPF filter to new interfaces relies on having access to and the privileges to open /dev/bpf, while AF_FRAME provides a wildcard listener that is able to receive LLDP from all interfaces on a single socket, like how binding to on 0.0.0.0 with an AF_INET socket let's you receive packets for all the IPs on your system from a single socket. lldp can create and configure this socket when it starts up just use it from then on. this means lldpd is simpler and needs fewer privileges to operate than if it went the BPF route.</p><p>at the moment lldpd only handles LLDP packet reception on all interfaces, you can't disable reception on interfaces yet. it also doesn't transmit LLDP packets (yet).</p><p>there is no intention of implementing any protocol other than LLDP in this daemon either.</p><p>ok djm@ deraadt@ general enthusiasm from many</p></blockquote>

Morgan Aldridge<p>While I've been trying to work outside as much as possible now that the weather is nice (for my mental health and to utilize my solar generator), today was chilly and started off rainy, so I was able to get a <a href="https://mastodon.social/tags/Twitch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Twitch</span></a> stream in. I worked on some <a href="https://mastodon.social/tags/MLVWM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MLVWM</span></a> & <a href="https://mastodon.social/tags/mlvwmrc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mlvwmrc</span></a> scripting to try to knock out some updates to my <a href="https://mastodon.social/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenBSD</span></a> APM (Advanced Power Management) Menu Extra:</p><p><a href="https://www.twitch.tv/videos/2446643155" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">twitch.tv/videos/2446643155</span><span class="invisible"></span></a></p>
Morgan Aldridge<p>Aside from the `sndio`-specific scripts & utilities, I've also been working on improving CBR (constant bitrate) and low-latency support in <span class="h-card" translate="no"><a href="https://bsd.network/@thfr" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>thfr</span></a></span>'s `ffmpeg`-based `fauxstream` (see <a href="https://github.com/rfht/fauxstream/issues/6" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/rfht/fauxstream/iss</span><span class="invisible">ues/6</span></a> & <a href="https://github.com/rfht/fauxstream/compare/master...morgant:fauxstream:fix-cbr-encoding" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/rfht/fauxstream/com</span><span class="invisible">pare/master...morgant:fauxstream:fix-cbr-encoding</span></a>).

Morgan Aldridge<p>Some cheap work lights with LED bulbs & home-made diffusers, my trusty Logitech C925e webcam and Blue Yeti X mic, a KORG nanoKONTROL2 MIDI controller for per-app audio levels & playback controls, plus a KORG FC6 MIDI foot controller (via M-Audio Uno USB MIDI interface) with KORG PS-2 pedals and some custom scripts abusing <a href="https://mastodon.social/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenBSD</span></a>'s <a href="https://mastodon.social/tags/sndio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sndio</span></a> <a href="https://mastodon.social/tags/MIDI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MIDI</span></a> support. The foot pedals provide system-wide push-to-talk for my mic, plus I have the foot controller configured to switch between virtual desktops. 3/n</p>
Continued thread
I've also spent months upgrading & rebuilding infrastructure, plus developing tools & processes. One such area has been my meetings/recording/streaming setup.
While finally regaining ability to sit at a desk for any period of time, funds are tight, so I'm still using a 2015 13in MacBook Air (dual-core 2.2GHz i7) running #OpenBSD as my primary workstation. Between my `xsndiomenu` & `recordctl` projects, some `mpv` wrapper scripts, @thfr's `fauxstream` (more on that shortly), it's easier. 2/n
