Functions

func CopyRegularFileByPath

func CopyRegularFileByPath(src, dst string) error

CopyRegularFileByPath copies a file from src to dst

func CopyRegularFileByRelativePath

func CopyRegularFileByRelativePath(srcName string, dstDir *os.File, dstName string) error

CopyRegularFileByRelativePath copies a file from src to dst, where destination is relative to a given directory

func CreateAt

func CreateAt(dir *os.File, relativePath string) (*os.File, error)

CreateAt implements the same logic as os.Create using directory FD and relative path.

func Dup

func Dup(file *os.File) (*os.File, error)

Dup is a wrapper function to the `dup` syscall using golang types.

func MkdirAt

func MkdirAt(dir *os.File, relativePath string, perm fs.FileMode) error

MkdirAt is a wrapper function to the `mkdirat` syscall using golang types.

func MkdirAtExist

func MkdirAtExist(dir *os.File, relativePath string, perm fs.FileMode) error

MkdirAtExist is a wrapper function to the `mkdirat` syscall using golang types, ignoring EEXIST error.

func OpenAt

func OpenAt(dir *os.File, relativePath string, flags int, perm fs.FileMode) (*os.File, error)

OpenAt is a wrapper function to the `openat` syscall using golang types.

func OpenExistingDir

func OpenExistingDir(path string) (*os.File, error)

OpenExistingDir open a directory with given path, and return the os.File of it.

func ParseSymbol

func ParseSymbol(address uint64, table *helpers.KernelSymbolTable) *helpers.KernelSymbol

func RenameAt

func RenameAt(olddir *os.File, oldpath string, newdir *os.File, newpath string) error

RenameAt is a wrapper function to the `renameat` syscall using golang types.
