Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation and all associated hamradio device drivers from the kernel tree. This set of protocols has long been a huge bug/syzbot magnet, and since nobody stepped up to help us deal with the influx of the AI-generated bug reports we need to move it out of tree to protect our sanity. The code is moved to an out-of-tree repo: https://github.com/linux-netdev/mod-orphan if it's cleaned up and reworked there we can accept it back. Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP, AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN) so that the conditional integration code in arp.c and tun.c continues to compile and work when the out-of-tree modules are loaded.

Linux 魔術數
|
||
============
|
||
|
||
這個文件是有關當前使用的魔術值註冊表。當你給一個結構添加了一個魔術值，你也應該把這個魔術值添加到這個文件，因爲我們最好把用於各種結構的魔術值統一起來。
|
||
|
||
使用魔術值來保護內核數據結構是一個非常好的主意。這就允許你在運行期檢查(a)一個結構是否已經被攻擊，或者(b)你已經給一個例行程序通過了一個錯誤的結構。後一種情況特別地有用---特別是當你通過一個空指針指向結構體的時候。tty源碼，例如，經常通過特定驅動使用這種方法並且反覆地排列特定方面的結構。
|
||
|
||
使用魔術值的方法是在結構的開始處聲明的，如下::
|
||
|
||
struct tty_ldisc {
|
||
int magic;
|
||
...
|
||
};
|
||
|
||
當你以後給內核添加增強功能的時候，請遵守這條規則！這樣就會節省數不清的調試時間，特別是一些古怪的情況，例如，數組超出範圍並且重新寫了超出部分。遵守這個規則，這些情況可以被快速地，安全地避免。

現在應該最新的Linux 2.1.112.因爲在特性凍結期間，不能在2.2.x前改變任何東西。這些條目被數域所排序。

更新魔術表到Linux 2.5.45。剛好越過特性凍結，但是有可能還會有一些新的魔術值在2.6.x之前融入到內核中。
