    More rust kernel hacking this evening and woo, got basic context switching!

  2. 31. sij

    Really liking how my little rust kernel is coming along, spent some time the last few days tidying up the networking stack, implementing a basic shared queue primitive, now also featuring prototype cpu detection and a working time widget.

    The "crisis" of declining readership of platforms that have refused to modernize in the age of the internet.

    They want to put media piracy on the same level as unauthorized broadcast retransmission.

    Recommendation 78: We recommend that to address piracy, sections 9 and 10 of the Radiocommunication Act — which state that it is an offence to decode, retransmit, or operate devices, equipment, or components to receive unlawfully decrypted subscription programs — be moved to the Broadcasting Act and be expanded to include all forms of media content, whether received through satellites or the Internet.

    We recommend that to promote the discoverability of Canadian news content, the CRTC impose the following requirements, as appropriate, on media aggregation and media sharing undertakings:

    links to the websites of Canadian sources of accurate, trusted, and reliable sources of news with a view to ensuring a diversity of voices; and
    prominence rules to ensure visibility and access to such sources of news.

    Now hooked in the basic read-eval processing so I can lookup arbitrary IP addresses (that all resolve to the same MAC address because qemu bridge)

    More rust kernel dev today, implemented some rough IPC so now I can do neat stuff like issuing ARP requests and async processing the response into the routing table which I can then fetch in the (very very basic) shell.

    Did some more rust kernel dev today, broke the networking stack into modules, then stress-tested the implementation using flood ping. Seems to be holding up well now.

    Thank you all! It was the damn IP checksums, which I didn't double check because wireshark has validation disabled by default! I can now ping my kernel!

    This is what the wireshark sees (both the dump from the kernel, and from wireshark listening on the bridging interface).

    Now with arp! and technically also icmp although that isn't quite working yet.

    Just spent the better part of a 4 hours trying to debug why interrupts weren't firing for received network packets despite seeing the packets in the buffer... turns out the pic8259_simple lib that "Writing an OS in Rust" uses doesn't support masking properly/at all 🙃 Finally!

    In a break from work, last night I started going through "Writing an OS in Rust " and then this morning I decided to try extending what I had to support the qemu network card and it works!

    To add to the ongoing ridiculousness of UK Counter Terrorism - don't be going around expressing extremist views like "we shouldn't put nuclear weapons everywhere", "we shouldn't kill all marine life" or "nazis are bad"

    As expected, green finds food by following red. Less unexpectedly is that as more green arrive at a food site red start avoiding them - eventually a threshold is reached where all the red actors "explode" outwards - preventing red getting stuck at one source.

    I've been playing around with emergent cooperation in , and have come across a really nice 2-actor model with red "food-finders/green avoiders" and green "red-finders"...
