Functions

func Chdir

func Chdir(dir string) error

func Chroot

func Chroot(dir string) error

func ClearKeepCaps

func ClearKeepCaps() error

func Clone

func Clone(flags uintptr) (int, error)

func CloseFdsFrom

func CloseFdsFrom(minFd int) error

Works similarly to OpenBSD's "closefrom(2)":

The closefrom() call deletes all descriptors numbered fd and higher from
the per-process file descriptor table.  It is effectively the same as
calling close(2) on each descriptor.

look in /proc to find the process start time so that we can verify that this pid has started after ourself

func Gettid

func Gettid() int

func Ioctl

func Ioctl(fd uintptr, flag, data uintptr) error

func LUtimesNano

func LUtimesNano(path string, ts []syscall.Timespec) error

func Lgetxattr

func Lgetxattr(path string, attr string) ([]byte, error)

func Mount

func Mount(source, target, fstype string, flags uintptr, data string) error

func OpenPtmx

func OpenPtmx() (*os.File, error)

OpenPtmx opens /dev/ptmx, i.e. the PTY master.

func OpenTerminal

func OpenTerminal(name string, flag int) (*os.File, error)

OpenTerminal is a clone of os.OpenFile without the O_CLOEXEC used to open the pty slave inside the container namespace
