Constants ¶
const MaxNameLen = 4096
MaxSendfdLen is the maximum length of the name of a file descriptor being sent using SendFd. The name of the file handle returned by RecvFd will never be larger than this value.

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 ¶ added in v0.0.8
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 CloseExecFrom ¶
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 GenerateRandomName ¶
GenerateRandomName returns a new name joined with a prefix. This size specified is used to truncate the randomly generated value
func GetIntSize ¶
func GetIntSize() int
func NewSockPair ¶
NewSockPair returns a new unix socket pair
func RecvFd ¶
RecvFd waits for a file descriptor to be sent over the given AF_UNIX socket. The file name of the remote file descriptor will be recreated locally (it is sent as non-auxiliary data in the same payload).
func ResolveRootfs ¶
ResolveRootfs ensures that the current working directory is not a symlink and returns the absolute path to the rootfs
func SearchLabels ¶ added in v0.1.0
SearchLabels searches a list of key-value pairs for the provided key and returns the corresponding value. The pairs must be separated with '='.
