Functions

func AppendSignature

func AppendSignature(outfilePath, modulefilePath, sigfilePath string) error

AppendSignature appends a raw PKCS#7 signature to the end of a given kernel module. This is basically the Go implementation of `scripts/sign-file -s` in Linux upstream.

func LoadModule

func LoadModule(module *Module, moduleParams ModuleParameters) error

LoadModule loads a given kernel module to kernel.

func LoadPublicKey

func LoadPublicKey(keyName, keyPath, keyring string) error

LoadPublicKey loads the given public key to system keyring.

func UpdateHostLdCache

func UpdateHostLdCache(hostRootDir, moduleLibDir string) error

UpdateHostLdCache updates the ld cache on host.
