Abstract
Disclosed are approaches for providing per-application tunnel access, such as virtual private network (VPN) access, in LINUX based systems. In response to an application requesting a network connection, a process identifier of the application and an inode identifier representing a socket for the network connection are obtained. Then, a kernel space map is updated to include the process identifier of the application and the inode identifier. In response to the application making a network connection request, the inode identifier of the application is obtained based at least in part on a source network address, a source port number, a destination network address, and a destination port number. Then, the kernel space map is queried to obtain the process identifier of the application, wherein the inode identifier is a query parameter. Then, a routing policy is identified based at least in part on the process identifier.
