RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
