| | * lib: Add missing check upon garbage collectionSander Vrijders2016-05-171-2/+3
| |/ | | | | | | | | | | | | There was a check missing upon garbage collection. If the whole DU map has been used once, all DUs will have their garbage bit set to one. This meant that the garbage collector would keep moving the tail indefinitely.
| * lib: Fixed incorrect initializationSander Vrijders2016-05-171-3/+4
|/ | | | | When moving the tail pointer in the DU map, blocks was never reset to zero. This caused it to sometimes clean up too many DUs.

| * lib: dev: small locking improvementsdimitri staessens2016-05-161-28/+33
| | | | | | | | | | | | This avoids holding the long locks during accept() and alloc_res() calls. Small reduction of time of other locks held. No changes in locking logic.

| * | | irmd: new locking implementationdimitri staessens2016-05-161-175/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This locking should be more consistent, It now has three locks, one guarding flows and port_id's, one guarding the registered apps and ipcps, and one guarding the overall state of the irmd. There are two additional mutexes guarding the condition variables.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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.
