Fedora 35: 2021-4cf4b682e8 Critical: Watchdog Memory Leak Fix

The watchdog program can be used as a powerful software watchdog daemon

or may be alternately used with a hardware watchdog device such as the

IPMI hardware watchdog driver interface to a resident Baseboard

Management Controller (BMC). watchdog periodically writes to /dev/watchdog;

the interval between writes to /dev/watchdog is configurable through settings

in the watchdog config file. This configuration file is also used to

set the watchdog to be used as a hardware watchdog instead of its default

software watchdog operation. In either case, if the device is open but not

written to within the configured time period, the watchdog timer expiration

will trigger a machine reboot. When operating as a software watchdog, the

ability to reboot will depend on the state of the machine and interrupts.

When operating as a hardware watchdog, the machine will experience a hard

reset (or whatever action was configured to be taken upon watchdog timer

expiration) initiated by the BMC.
