Constants ¶
const PR_SET_CHILD_SUBREAPER = 36
If arg2 is nonzero, set the "child subreaper" attribute of the calling process; if arg2 is zero, unset the attribute. When a process is marked as a child subreaper, all of the children that it creates, and their descendants, will be marked as having a subreaper. In effect, a subreaper fulfills the role of init(1) for its descendant processes. Upon termination of a process that is orphaned (i.e., its immediate parent has already terminated) and marked as having a subreaper, the nearest still living ancestor subreaper will receive a SIGCHLD signal and be able to wait(2) on the process to discover its termination status.

Functions ¶
func ClearKeepCaps ¶
func ClearKeepCaps() error
func GetClockTicks ¶
func GetClockTicks() int
func GetProcessStartTime ¶
look in /proc to find the process start time so that we can verify that this pid has started after ourself
func Lgetxattr ¶
Returns a []byte slice if the xattr is set and nil otherwise Requires path and its attribute as arguments
func Llistxattr ¶
Returns the size of xattrs and nil error Requires path, takes allocated []byte or nil as last argument
func RunningInUserNS ¶
func RunningInUserNS() bool
RunningInUserNS detects whether we are currently running in a user namespace. Copied from github.com/lxc/lxd/shared/util.go
func SetKeepCaps ¶
func SetKeepCaps() error
func SetParentDeathSignal ¶
func SetSubreaper ¶
SetSubreaper sets the value i as the subreaper setting for the calling process
Types ¶

type ParentDeathSignal int
func GetParentDeathSignal ¶
func GetParentDeathSignal() (ParentDeathSignal, error)
