|/ | | | | This makes sure only one shm_du_map is running in the system. Starting a second irmd would invalidate the shared memory map.

| | | | | | | | | | A read lock was taken instead of a write lock, which resulted in double frees.

| * lib, ipcpd, irmd: fixes deallocation and fast pathdimitri staessens2016-05-224-37/+47
|/ | | | | | The fast path has been rewritten to have certainty to read the correct flow. Deallocation will not release port_id's or fd's until they are explicitly released locally.

|/ | | | | | The shim UDP now supports deallocating a flow end-to-end. Contains some stability fixes for flow allocation and some missing close() calls in lib/sockets.

|\ | | | | | | ipcpd: Full flow allocation for the shim UDP
| * ipcpd: shim-udp: read fd on client sidedimitri staessens2016-05-201-0/+13
| | | | | | | | | | There could be a theoretical race condition that the server sends a message before the FD is set on the client side, which is resolved.
| * ipcpd: shim-ipcp: fixed race conditionsdimitri staessens2016-05-201-40/+57
| | | | | | | | | | | | | | | | | | | | | | There were two race conditions. The first was where client received the response message before the client UDP port was connected to the server UDP port and the first message of the client was sent to the LISTEN port instead of the server application port. This was solved by reordering the operations so the response is sent after the port is correctly connected. The second race condition is that the FD is not added to the set in time at the server side before the first SDU arrives. This was solved by adding a variable proteceted by a mutex.
| * ipcpd: shim-udp: removed debug codedimitri staessens2016-05-191-12/+0
| | | | | | | | | | some debug code for locking and a sleep check are removed from the shim-udp.
| * Implementation of a full flow allocator for the shim UDP.dimitri staessens2016-05-186-258/+540
|/ | | | | | | | | It uses UDP port 0x0D1F on all hosts to send and receive flow allocation messages. It supports communication between server and client AP over a single shim IPCP. Implementation of full flow deallocation is pending. Both the client and the server still have to call flow_dealloc();

| | * 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.

| | | | | | | | | | | | 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.

| * | | 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.
