Functions

func GetCurrentNamespace

func GetCurrentNamespace() *tetragon.Namespaces

func GetHostNsInode

func GetHostNsInode(nsStr string) (uint32, error)

func GetMsgNamespaces

func GetMsgNamespaces(ns processapi.MsgNamespaces) (*tetragon.Namespaces, error)

func GetMyPidG

func GetMyPidG() uint32

func GetPidNsInode

func GetPidNsInode(pid uint32, nsStr string) (uint32, error)

GetPidNsInode() returns the inode of the target namespace pointed by pid. Returns:

namespace inode and nil on success
0 and error on failures.

func GetSelfNsInode

func GetSelfNsInode(nsStr string) (uint32, error)

func InitHostNamespace

func InitHostNamespace() (*tetragon.Namespaces, error)

InitHostNamespace() Initialize host namespaces.

This function is explicitly inside a once.Do() as we have to initialize host namespaces only once, no need to access /proc/1/ multiple times.

Returns:

Host namespaces as a tetragon.Namespaces object on success
Nil and an error on failure

func IsMsgNsInHostMntUser

func IsMsgNsInHostMntUser(ns *processapi.MsgNamespaces) (bool, error)
