Bug ID: 26599
Summary: eu-readelf -n works on /boot/vmlinuz-* but
debuginfod-find doesn't
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: debuginfod
Assignee: unassigned at sourceware dot org
Reporter: fche at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
eu-readelf appears to unwrap the bzImage header on a vmlinuz kernel file, and
can thus extract buildids, but debuginfod-find cannot:
% eu-readelf -n /lib/modules/5.7.15-200.fc32.x86_64/vmlinuz
[...]
GNU 20 GNU_BUILD_ID
Build ID: 8820b044b7717b53bd9a9795a1fbca152d2fae63
% debuginfod-find debuginfo /lib/modules/5.7.15-200.fc32.x86_64/vmlinuz
Cannot extract build-id from /lib/modules/5.7.15-200.fc32.x86_64/vmlinuz:
invalid `Elf' handle
It would be handy to teach debuginfod-find how to use the elfutils entry point
that unwraps bzImage.
