Subject: [RESEND] Request for VSOCK backport to 4.4 stable

Hello,

We’d like the following commit to be backported to 4.4 stable. The commit fixes a bug that was introduced in 4.3 and fixed in 4.6. The bug may cause wrongful termination of vSocket connections, if there is more than one active vSocket connection in a given VM. This affects customers running the normal VMware services inside VMs :

commit	8ab18d71de8b07d2c4d6f984b718418c09ea45c5 

VSOCK: Detach QP check should filter out non matching QPs.

The check in vmci_transport_peer_detach_cb should only allow a
detach when the qp handle of the transport matches the one in
the detach message.

Thanks,
Jørgen
