The vsock flags can be set during the connect() setup logic, when
initializing the vsock address data structure variable. Then the vsock
transport is assigned, also considering this flags field.
The vsock transport is also assigned on the (listen) receive path. The
flags field needs to be set considering the use case.
Set the value of the vsock flags of the remote address to the one
targeted for packets forwarding to the host, if the following conditions
are met:
* The source CID of the packet is higher than VMADDR_CID_HOST.
* The destination CID of the packet is higher than VMADDR_CID_HOST.
Changelog
v3 -> v4
* No changes.
v2 -> v3
* No changes.
v1 -> v2
* Set the vsock flag on the receive path in the vsock transport
assignment logic.
* Use bitwise operator for the vsock flag setup.
* Use the updated "VMADDR_FLAG_TO_HOST" flag naming.
