Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

Valgrind log from aarch64 machine
When running systemd under valgrind in nspawn container, on some architectures (ppc64, ppc64le and aarch64) boot process ends with an error due to unhandled syscalls. Running systemd without valgrind works as expected.
Version-Release number of selected component (if applicable):
valgrind-3.10.0-16.el7.aarch64
How reproducible:
## Create a minimal nspawn container
# mkdir vm
# yum -y --nogpgcheck --installroot $PWD/vm groupinstall minimal
# cp -f /etc/yum.repos.d/* vm/etc/yum.repos.d/
# yum -y --nogpgcheck --installroot $PWD/vm install valgrind
## Run systemd under valgrind in nspawn container
# systemd-nspawn -D vm/ valgrind --leak-check=full --log-file=valgrind.log /usr/lib/systemd/systemd
Actual results:
Boot process ends with an error:
Failed to enable ctrl-alt-del handling: Function not implemented
Failed to wait for system-generators: Function not implemented
...
Failed to run main loop: Function not implemented
[!!!!!!] Failed to run main loop, freezing.
Expected results:
Container should boot successfully as tested on x86_64 and s390x architectures.
Additional info:
Valgrind log with unhandled syscalls is included in the attachment.
The specific aarch64 syscalls mentioned in the attachment are:
WARNING: unhandled syscall: 142 (reboot)
WARNING: unhandled syscall: 264 (name_to_handle_at)
WARNING: unhandled syscall: 278 (getrandom)
WARNING: unhandled syscall: 81 (sync)
WARNING: unhandled syscall: 95 (waitid)
sync and waitid are already implemented upstream and backported to the valgrind-3.11.0 package. name_to_handle_at and getrandom are implemented on other arches and should be easy to enable for aarch64 too. reboot isn't implemented anywhere yet.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
