AArch64 上的堆栈金丝雀存储在哪里？
[英]Where is the stack canary stored on AArch64?
问题描述
Is there a special space for ARM64 to store the stack canary, like the %fs:<offset> on x86_64? 
ARM64 是否有特殊的空间来存储堆栈金丝雀，例如 x86_64 上的%fs:<offset> ？ Where is the thread-local storage (TLS) stored for ARM64? ARM64 的线程本地存储 (TLS) 存储在哪里？

To the best of my knowledge arm64 Linux kernel is still adopting the old design with StackGuard , using one global canary for the whole kernel (confirmed by this paper. . (Stackguard explanation is here ). This line of arm64 Makefile seems to further confirm this.

About the second question in (arm64) tls.h there is a bunch of definitions for TLS, mainly used in (arm64) process.c .关于 (arm64) tls.h中的第二个问题，TLS 有一堆定义，主要用于 (arm64) process.c中。
