Functions

func C2GoArray

func C2GoArray(str string) []byte

C2GoArray transforms an hexadecimal string representation into a byte slice. Example: str := "0x12, 0xff, 0x0, 0x1" fmt.Print(C2GoArray(str)) //`{0x12, 0xFF, 0x0, 0x01}`"

func FindEPConfigCHeader

func FindEPConfigCHeader(basePath string, epFiles []os.FileInfo) string

FindEPConfigCHeader returns the full path of the file that is the CHeaderFileName from the slice of files

func GetCiliumVersionString

func GetCiliumVersionString(epCHeaderFilePath string) (string, error)

GetCiliumVersionString returns the first line containing CiliumCHeaderPrefix.

func MapStringStructToSlice

func MapStringStructToSlice(m map[string]struct{}) []string

MapStringStructToSlice returns a slice with all keys of the given map[string]struct{}

func MoveNewFilesTo

func MoveNewFilesTo(oldDir, newDir string) error

MoveNewFilesTo copies all files, that do not exist in newDir, from oldDir.

func RequireRootPrivilege

func RequireRootPrivilege(cmd string)

RequireRootPrivilege checks if the user running cmd is root. If not, it exits the program
