Status ASSIGNED MODIFIED
Fixed In Version glibc-2.34-28.el9_0.1
Doc Text Feature: Compatibility with rseq symbols from RHEL 9.1 glibc

Reason: In Red Hat Enterprise Linux 9.1, glibc adds additional rseq-related symbols from the upstream glibc 2.35 version. If applications use these symbols, they will not launch on Red Hat Enterprise Linux 9.0.

Result: With these symbols added, applications built against RHEL 9.1 glibc will start even if they use rseq. Note that rseq registration remains disabled by default in RHEL 9.0 for compatibility reasons, but it can be enabled using the glibc.pthread.rseq=1 tunable.
