[Перевод] Пишем стек TCP/IP с нуля: Ethernet, ARP, IPv4 и ICMPv4

Написание собственного стека TCP/IP поначалу может показаться пугающей задачей. И в самом деле, за свой тридцатилетний срок жизни TCP впитал в себя множество спецификаций. Однако базовая спецификация остаётся относительно компактной1 — из важных частей в ней можно выделить парсинг заголовков TCP, машину состояний, отслеживание перегрузок и вычисление таймаута повторной передачи. Самые распространённые протоколы слоя 2 и слоя 3, Ethernet и IP, скромны по сравнению с сложностью TCP. В этой серии статей мы реализуем минимальный стек TCP/IP пользовательского пространства для Linux. Посты и код служат исключительно в образовательных целях, они позволят вам глубже изучить сетевое и системное программирование.

saminiir's hacker blog · Mar 6, 2016Let's code a TCP/IP stack, 1: Ethernet & ARPWriting your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact[^tcp-roadmap] - the important parts being TCP header parsing, the state machine, congestion control and retransmission timeout computation.

Ich habe mir gerade einen Termin für den 01.01.2032 eingetragen . Denn ich wurde heute von der #Bafa informiert, dass die Förderung unserer Wärmepumpe (2023) mit EU-Mitteln erfolgte und wir deshalb sichtbar eine A5-große »Finanzierungserklärung« z. B. am Briefkasten,… anbringen müssen. Die Pflicht »sichtbar darauf hinzuweisen« gilt bis zum 31.12.2031. Dem kommen wir doch gerne nach. Ich freue mich auf die Fragen, warum unser Briefkasten gefördert wurde …

Also v8 of my patchset for the @batadv #DistributedARPTable to reduce #ARP overhead is out now. Which fixes some error handling bugs I had accidentally introduced in v7, which were spotted during another review.
https://patchwork.open-mesh.org/project/b.a.t.m.a.n./list/?series=627&state=%2A&archive=both
Hopefully this will now get closer to getting merged upstream?

#jamuary 9 is my 5th track since the beginning of the year. Almost gave up but someone reached out and said they were really looking forward to my next #jam, so I pushed forward and published some #downtempo #ambient. A little more lively than the previous but still fairly #chill. There is an element from video games in that there is a square lead from a Texas Instrument chip in there. Drowned in space reverb. #music #soundcloud #electronica #crumar #Elka #arp #korg

The Defence Minister is considering a relatively unlikely level of conflict (and losses), but this seems like a subtle call for a modern "Dad's Army" (and surely we may need an equivalent of the #ARP against #cyberthreats and #sabotage and also repair parties to fix any #infrastructure which does get damaged in #WW3 ? )

‘Learn how to safely catch funnel-webs’

“Male funnel-web spiders have short lifespans, and with approximately 150 spiders required to make just one vial of antivenom, we need the public’s help to ensure we have enough venom to meet demand,” — #EmmaTeni

#ARP / #spiders / #FunnelWebs / #sydney <https://theguardian.com/australia-news/2024/nov/15/australia-sydney-funnel-web-spider-season-reptile-park-callout>

“the yearly callout, which ARP stresses is “quite safe”, is likely to have saved hundreds of lives.

The post advised people to scan a QR code “to learn how to safely catch funnel-webs and their egg sacks”.

The collected little spiders are raised at the ARP for their venom, which has been used to create vital antivenom for the species since 1981. Thanks to the program, no deaths have been recorded from a funnel-web spider bite in four decades.”

@goetz @ffhl I needed a while to figure out what practical benefit we would have. One thing that came to my mind: Avoiding #ARP on supporting devices completely if I understand #ipv6mostly correctly. We do have a DHT for ARP in #batman_adv. And could reduce broadcasts a lot with it. But it's still not zero. #IPv6 is so much smarter for Neighbor Discovery as it uses #multicast properly with its solicited mcast addresses and not like broadcasts. And we have #MLD snooping in our #mesh.
