Description Frank Ch. Eigler 2019-12-02 19:49:04 UTC

It appears the debuginfod_find_* calls are not being attempted for elfutils/libdwfl work related to the kernel:

% DEBUGINFOD_URLS=http://localhost/ stap -p2 -e 'probe kernel.function("do_exit") {}'

... generates no traffic to localhost if kernel-debuginfo* is not already installed.

Comment 1 Mark Wielaard 2019-12-05 16:56:11 UTC

Patch posted upstream: https://sourceware.org/ml/elfutils-devel/2019-q4/msg00234.html

Comment 2 Mark Wielaard 2019-12-11 15:26:17 UTC

The main fix is in upstream and the fedora elfutils-0.178-6 package already.
To get better diagnostics on download progress a patch is under discussion upstream
(a workaround for now would be to set the DEBUGINFOD_TIMEOUT env var to some large value).

Comment 3 Mark Wielaard 2019-12-13 22:55:26 UTC

Added first patch for the main bug. debuginfod progress/timeout fix might follow later.
