Variables ¶
var NativeEndian binary.ByteOrder
NativeEndian is the native byte order of the host system.
Functions ¶
func Annotations ¶
Annotations returns the bundle path and user defined annotations from the libcontainer state. We need to remove the bundle because that is a label added by libcontainer.
func CleanPath ¶
CleanPath makes a path safe for use with filepath.Join. This is done by not only cleaning the path, but also (if the path is relative) adding a leading '/' and cleaning it (then removing the leading '/'). This ensures that a path resulting from prepending another path will always resolve to lexically be a subdirectory of the prefixed path. This is all done lexically, so paths that include symlinks won't be safe as a result of using CleanPath.
func ExitStatus ¶
func ExitStatus(status unix.WaitStatus) int
ExitStatus returns the correct exit status for a process based on if it was signaled or exited cleanly
func SearchLabels ¶
SearchLabels searches through a list of key=value pairs for a given key, returning its value, and the binary flag telling whether the key exist.
func WithProcfd ¶
WithProcfd runs the passed closure with a procfd path (/proc/self/fd/...) corresponding to the unsafePath resolved within the root. Before passing the fd, this path is verified to have been inside the root -- so operating on it through the passed fdpath should be safe. Do not access this path through the original path strings, and do not attempt to use the pathname outside of the passed closure (the file handle will be freed once the closure returns).
