Implementing sframes - Challenges and Solutions

Explore the implementation challenges of sframes in this 24-minute conference talk from the Linux Plumbers Conference. Dive into how sframes, added to binutils, enable kernel-level user space stack tracing without frame pointers. Examine key issues including reading potentially faulting user space, postponing stack traces in perf and ftrace, and handling dynamically linked objects and JIT code. Learn about proposed solutions such as loading sframe information from ELF files and potential new system calls for dynamic stack tracing.
