The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
The kernel-rt packages have been upgraded to the 3.10.0-957.5.1 source tree, which provides a number of bug fixes over the previous version. (BZ#1653822)
Under certain circumstances, the following warning message, which indicated a SCHED_DEADLINE bandwidth tracking mechanism error, occurred:
WARNING: CPU: 8 PID: 19536 at kernel/sched/deadline.c:64 dequeue_task_dl+0x121/0x140
This update fixes the sched_setscheduler() core kernel function, and backports multiple upstream patches to the SCHED_DEADLINE scheduler. As a result, the SCHED_DEADLINE bandwidth tracking mechanism is prevented from error conditions, and the warning message no longer occurs. (BZ#1655439)
