Fedora 33 2021-a5b584004c Moderate: LinuxPTP Security Fixes

This software is an implementation of the Precision Time Protocol (PTP)

according to IEEE standard 1588 for Linux. The dual design goals are to provide

a robust implementation of the standard and to use the most relevant and modern

Application Programming Interfaces (API) offered by the Linux kernel.

Supporting legacy APIs and other platforms is not a goal.
