Bug 823692 – net-misc/ntpsec-1.2.1[seccomp]: broken with glibc-2.34

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Klemen Mihevc 2021-11-14 08:36:21 UTC]

ntpsec with seccomp enabled does not run with new glibc, no errors in the logs, but error usualy happens after every glibc update because of updated syscalls. If you dont use seccomp it works fine.

Reproducible: Always

Could you run strace on it when it fails?
