* datapath-windows: Fix bugs in Event.c around subscribe and lockSairam Venugopal2016-07-292-5/+8
| | | | | | | | | | | | | | | | | | | | When userspace tries to resubscribe to an existing queue, return STATUS_INVALID_PARAMETER since it's not supported. The current bug overwrites status to STATUS_SUCCESS. The second bug fix is around releasing the EventQueue lock if an open instance couldn't be found. The current version returns back without releasing the lock. Moving the OvsAcquireEventQueueLock() after the instance is verified. OvsGetOpenInstance does not enforce a safe read for gOvsSwitchContext->dpNo. Use the gOvsSwitchContext->dispatchLock for accessing the parameter.

* Windows: Add support for handling protocol (netlink family)Sairam Venugopal2016-07-133-3/+119
| | | | | | | | | | | | | | | Windows datapath currently has no notion of netlink family. It assumes all netlink messages to belong to NETLINK_GENERIC family. This patch adds support for handling other protocols if the userspace sends it down to kernel. This patch introduces a new NETLINK_CMD - OVS_CTRL_CMD_SOCK_PROP to manage all properties associated with a socket. The properties are passed down as netlink message attributes. This makes it easier to introduce other properties in the future.
