Frank Ch. Eigler 2018-05-07 20:15:14 UTC Doc Text Cause: Kernel changes related to ASLR.

Vladimír Slávik 2018-05-10 17:31:32 UTC Doc Text Cause: Kernel changes related to ASLR.

Consequence: Systemtap kernel backtraces were incomplete.

Fix: Added proper handling of ASLR for backtracing, and an additional fallback backtracing mechanism.

Result: Backtraces now work on this ASLR scheme.
Because of changes in kernel related to address space layout randomization (ASLR), kernel backtraces collected by the SystemTap tool became incomplete. SystemTap has been extended to handle this situation. As a result, SystemTap can provide complete kernel backtraces again.
