fedora
Calendar Grey May 4, 2024
Dist Fedora Esm H88
Mitigate vulnerabilities during the dynamic deployment of application services on Fedora. Recent enhancements improve thread handling efficiency.
address issues found in Static Application Security testing Fix a service startup issue Fix file open issue when kernel lockdown is in effect

Summary

The stalld program monitors the set of system threads,

looking for threads that are ready-to-run but have not

been given processor time for some threshold period.

When a starving thread is found, it is given a temporary

boost using the SCHED_DEADLINE policy. The default is to

allow 10 microseconds of runtime for 1 second of clock time.
