(Hit ==Esc== to see the map) About This is a collection of materials that I watch/read through my journey of leaning the kernel. Over time, I found that there are more and more moments where I say "let me send a cool conference video to you and you'll know". That was the moment where I thought I should make this list! About Don't worry about the amount of information here! Those are the results of decades of collaboration of human minds, like all the amazing architecture in the world.

This is a very long list of talks and references for the Linux kernel subsystems. I enjoy stories. People in the conferences all tell great stories about subsystems in Linux, so I collect them, trying to make a Grimm's Fairy Tales for Linux. I’d also like to think of it as a drawing book. It may seem empty at first, just a list of talks. More contents will be added as the journey continues. This could also be a first-aid kit before getting involved in an unknown subsystem. Looking at a few of them may be sufficient for gaining a bird-eye view and start the exploration. This greatly eases the learning curve, at least for me. Technically the elinux.org serves similar purpose, but some of its contents seems to be outdated. Would be nice if some of these contents could be merged to eLinux.

References Michael Kerrisk 是 TLPI 的作者，也是 man-pages 的維護者所以可能聽一聽會以為他在唸照著 man 唸。如果懶得聽他講的話，也可以直接去看 man。同時他在 LWN 上也以 Namespaces in Operation 為題，寫了一系列介紹不同種類的 namespace 的文章及範例程式。 以下的資料多半會講「namespace 有 7 種」。但在 2020 年一月 (5.6 版的 kernel) 時，新增了一個 Time Namespace。所以實際上現在已經有 8 種了。 Containers unplugged (Part 1): Linux namespaces - Michael Kerrisk Rootless Containers from Scratch - Liz Rice, Aqua Security Linux Container Primitives: cgroups, namespaces, and more!

簡介 (圖片來源：Netfilter hooks) 參考影片 (Pablo Neira Ayuso) 要理解 netfilter 希望達成什麼功能，從它的命令列前端理解起或許比較方便。netfilters 的一個命令列前端是 nftables (nft)。而關於 nftables，他的維護者之一的 Pablo Neira Ayuso 有不少演講。以下前三個演講都是他親自介紹，這三個演講中涵蓋了 nft 官方文件 中大部分的內容。而且這些解說都是獨立的講解，沒有使用 nftables 前身的 iptables 或各種 *tables 的經驗也可以看懂，是個人認為目前找到最棒的解說。 除了影片之外，netables 的維基百科上也有大抄。 如果想要知道 nftables 第一眼看過去有點詭異的術語們是怎麼來的，可以看看 KEYNOTE: netf‌ilter archeology: 18 years from Linux 2.3 to 4.x 這個 netfilters 的歷史介紹。
