-K' The -K (sure kill) option is like -k except that it removes the user's cached credentials entirely and may not be used in conjunction with a command or other option. This option does not require a password. Not all security policies support credential caching.
-k [command] When used alone, the -k (kill) option to sudo invalidates the user's cached credentials. The next time sudo is run a password will be required. This option does not require a password and was added to allow a user to revoke sudo permissions from a .logout file. Not all security policies support credential caching.
When used in conjunction with a command or an option that may require a password, the -k option will cause sudo to ignore the user's cached credentials. As a result, sudo will prompt for a password (if one is required by the security policy) and will not update the user's cached credentials.
Linux (and therefor the Pi) hasn't supported RARP for a number of years now. Possibly over a decade ago. It's an obsolete protocol and really should not be used.
Compilation or cross-compilation is done by setting CPU variable for make command:
make CPU=k8 tests # Builds for x86_64 (default CPU value) make CPU=armv7a tests # Builds for ARMv7-A, e.g. Pi 3 or Pi 4 make CPU=aarch64 tests # Builds for ARMv8, e.g. Coral Dev Board
