| |/ |/| | | | | | | | | | | Added necessary locks for the shim-udp. This PR also improves thread management, the main thread now starts a mainloop thread, which spawns sdu handler threads when it the IPCP is enrolled. If the IPCP exits the enrolled state, the sdu loop is cancelled.

|/ | | | | | This allows someone to disable the use of DNS in the shim UDP. It also adds a config file specific for the shim UDP (which holds the nsupdate location). Certain defines were also moved to the global config file.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit has a first implementation of flow allocation (the "slow path") and read/write (the "fast path") for ouroboros. It provides basic but unstable communications over the shared memory. It required a lot of changes all over the stack, and fixes a number of previously undetected issues. This PR still need heavy revision regarding data model, locking and cleanup. lib/dev: modifications to the API. It now uses an ap_init() call to set the AP name and sets the Instance ID to the pid of the process. It also binds the AP to the shared memory and creates tables for mappings in the fast path. A call to ap_fini() releases the resources. lib/shm_ap_rbuff: added ring buffer for data exchange between processes in the fast path. It passes an index in the shm_du_map. lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage collector added. Tests updated to new API. ipcpd/ipcp-data: removed everything related to flows, as these are universal for all ap's and kept in ap_data (dev.c), or similar structs for shim ipcps. shim-udp: added flow allocator and read/write functions and shm elements. irmd: revised data model and structures necessary for flow allocation. tools: echo updated to new dev.h API. messaging system was updated to comply with new flow allocation messages. All exchanges use pid and port_id to bootstrap the fast path.
