Bug Description

For time synchronisation Linux currently supports Server Time Protocol (STP).
STP was explicitly not used as time source for Linux system time, due to several reasons:
- STP is not virtualized (neither z/VM, nor KVM have STP virtualization support)
- missing leap second support for STP in Linux

This feature implements leap second functionality for STP.

Business Case:
HW support, z/OS interoperability

This is the kernel part of the requested feature.
Will be made available with kernel 5.10.

Integrated via kernel update.
