Functions

func ClearBit

func ClearBit(n *uint64, offset uint)

func ClearBits

func ClearBits(n *uint64, mask uint64)

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. This function needs needed capabilities to be set before it is called.

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 HasBit

func HasBit(n uint64, offset uint) bool

func IsDirEmpty

func IsDirEmpty(pathname string) (bool, error)

IsDirEmpty returns true if directory contains no files

func Max

func Max(x, y uint64) uint64

func Min

func Min(x, y uint64) uint64

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(p 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 RemoveAt

func RemoveAt(dir *os.File, relativePath string, flags int) error

RemoveAt is a wrapper function to the `unlinkat` syscall using golang types.

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.

func SetBit

func SetBit(n *uint64, offset uint)
