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)
