Accepted Session
Live Kernel Patching
Microconference Session

One Line Summary

Compare the design and features of kpatch and kGraft and figure out if we can combine the two approaches, or take any other steps to get a live patching solution merged into mainline.

Abstract

  • Design comparison
  • Feature comparison (kernel)
  • Is there any way to combine the kernel implementations?
  • Feature comparison (user space)
  • Is there any way to combine the user space implementations?
  • Should we put the user space tools in the kernel tree?
  • What steps can we take to get a live patching solution merged into mainline?
