AArch64 上的堆栈金丝雀存储在哪里？

Question

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> ？ ARM64 的线程本地存储 (TLS) 存储在哪里？

Answer 1

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 .

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。
