Functions

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 FmtDefineAddress

func FmtDefineAddress(name string, addr []byte) string

FmtDefineAddress returns the a define string from the given name and addr. Example: fmt.Print(FmtDefineAddress("foo", []byte{1, 2, 3})) // "#define foo { .addr = { 0x1, 0x2, 0x3 } }\n"

func FmtDefineArray

func FmtDefineArray(name string, array []byte) string

FmtDefineArray returns the a define string from the given name and array. Example: fmt.Print(FmtDefineArray("foo", []byte{1, 2, 3})) // "#define foo { 0x1, 0x2, 0x3 }\n"

func FmtDefineComma

func FmtDefineComma(name string, addr []byte) string

func GetCiliumVersionString

func GetCiliumVersionString(epCHeaderFilePath string) (string, error)

GetCiliumVersionString returns the first line containing CiliumCHeaderPrefix.

func GetGroupIDByName

func GetGroupIDByName(grpName string) (int, error)

GetGroupIDByName returns the group ID for the given grpName.

func RequireRootPrivilege

func RequireRootPrivilege(cmd string)

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

func SetupLogging

func SetupLogging(loggers []string, logOpts map[string]string, tag string, debug bool) error

SetupLogging sets up each logging service provided in loggers and configures each logger with the provided logOpts.
