Description

Something is broken when debugging non-relocatable binaries. Hermit loads these correct, but reporting the kernel_address as offset (https://github.com/hermit-os/uhyve/blob/08f042ff9e82a1c3bab6143b71bbabb11cc539bb/src/linux/gdb/section_offsets.rs#L7) results in incorrect addresses.

Contributor guide

Research direction
Investigate the section offsets.rs file in uhyve/src/linux/gdb/ and understand how kernel address is computed for non relocatable binaries. Trace the logic to see why offsets are incorrect and propose a fix.
