* ipcpd: shim-udp: Revised lockingdimitri staessens2016-05-152-96/+97
| | | | | | | | | | Simplified locking to take only two locks: the first lock guards the state of the ipcp. This lock must be held for writing on bootstrap and closing, and held for reading during all other operations. The second lock guards operations on flows, and must be held for writing during allocation and deallocation, and held for reading when sending sdu's. After adding a fd to FD_SET, the shim will wait for 1 ms to ensure that the FD is added to the select call.

|/ | | | | This takes a lock before notifying the IRMd of a new flow request, to avoid race conditions when trying to retrieve the fd by port-id.

| | | | | | | | | | | | This fixes wrong header inclusion that would make programs which are not developed within ouroboros fail upon compilation, since they would not find certain headers on their system.

| * | lib, ipcpd, irmd: Add QoS cube definitionSander Vrijders2016-05-1416-109/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the QoS cube definition, which is an enum to select which QoS is needed in the IPCP. An application has to use the qos_spec in qos.h to define what it needs. The IRMd will map this unto a qos cube definition. Some headers are now also no longer installed on the system, since they are only to be used within the irmd and ipcps.
