[libvirt] [PATCH v3 3/3] qemu: Correctly label migration TCP socket

[Jiri Denemark]

---
Notes:
    Version 3:
    - use virSecurityManagerSetSocketLabel/virSecurityManagerClearSocketLabel
      pair around virNetSocketNewConnectTCP to label the newly created socket
      with svirt_t

    Version 2:
    - use virSecurityManagerSetProcessFDLabel instead of
      virSecurityManagerSetImageFDLabel since the correct label for
      TCP sockets appears to be svirt_t and not svirt_image_t
