Variables ¶

var EpollCreate1 = unix.EpollCreate1

EpollCreate1 is an alias for unix.EpollCreate1 Deprecated: use golang.org/x/sys/unix.EpollCreate1

var EpollCtl = unix.EpollCtl

EpollCtl is an alias for unix.EpollCtl Deprecated: use golang.org/x/sys/unix.EpollCtl

var EpollWait = unix.EpollWait

EpollWait is an alias for unix.EpollWait Deprecated: use golang.org/x/sys/unix.EpollWait

var RunningInUserNS = userns.RunningInUserNS

RunningInUserNS detects whether we are currently running in a user namespace. Deprecated: use github.com/containerd/containerd/pkg/userns.RunningInUserNS instead.

Functions ¶

func AdjustOOMScore ¶

func AdjustOOMScore(pid, score int) error

AdjustOOMScore sets the oom score for the provided pid. If the provided score is out of range (-1000 - 1000), it is clipped to the min/max value.

func CreateUnixSocket ¶

func CreateUnixSocket(path string) (net.Listener, error)

CreateUnixSocket creates a unix socket and returns the listener

func FMountat ¶

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

FMountat performs mount from the provided directory.

func ForceRemoveAll ¶

func ForceRemoveAll(path string) error

ForceRemoveAll on unix is just a wrapper for os.RemoveAll

func GetLocalListener ¶

func GetLocalListener(path string, uid, gid int) (net.Listener, error)

GetLocalListener returns a listener out of a unix socket.

func GetOOMScoreAdj ¶

func GetOOMScoreAdj(pid int) (int, error)

GetOOMScoreAdj gets the oom score for a process. It returns 0 (zero) if either no oom score is set, or a sore is set to 0.

func GetOpenFds ¶

func GetOpenFds(pid int) (int, error)

GetOpenFds returns the number of open fds for the process provided by pid

func MkdirAllWithACL ¶

func MkdirAllWithACL(path string, perm os.FileMode) error

MkdirAllWithACL is a wrapper for os.MkdirAll on Unix systems.

func SetOOMScore ¶

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the provided pid

func StatATimeAsTime ¶

func StatATimeAsTime(st *syscall.Stat_t) time.Time

StatATimeAsTime returns st.Atim as a time.Time

func StatAtime ¶

func StatAtime(st *syscall.Stat_t) syscall.Timespec

StatAtime returns the Atim

func StatCtime ¶

func StatCtime(st *syscall.Stat_t) syscall.Timespec

StatCtime returns the Ctim

func StatMtime ¶

func StatMtime(st *syscall.Stat_t) syscall.Timespec

StatMtime returns the Mtim
