| | | | | | | | | | it's more robust to use dedicated locks for pthread_cond_signal so no other threads can be waiting for the mutex.

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

| | | | | | | | | | | | | | | | | | This commits adds the gethostbyname call to resolve the dst_name for a flow allocation using DNS. The DNS server should be specified using the method mandated by the system (e.g. added to /etc/resolv.conf).

| | | | | | | | | | | | | | | | | | | | | | | | All instance-id's in ouroboros will be set by the system to the pid of the process associated with this application process instance. This means that the user has no way to choose the instance id's. Function calls that assumed manually defined instance id's have been replaced throughout the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unregistering ap's now works. An AP now registers/unregisters its AP-I by sending its AP name and its pid to the IRMd. The IPCPs register whatevercast names. An AP name is currently mapped on a whatevercast name represented by the same string literal. The IRMd allows registration of only one AP-I per AP. A Name Space Management system is needed in the processing system so we can resolve this completely. Changing the stack to register whatevercast names required some changes all over the ipcpd implemented and in the library.

The shims currently does the following. The shim IPCP binds to an interface (IP address) and listens for flow allocation requests on UDP port 0x0D1F (3359), referenced as the listen port (lp). It will treat any datagram received on lp as a flow allocation request. Upon receiving an allocation request IRM_MSG_CODE__IPCP_FLOW_ALLOC from the IRMd, the shim IPCP will bind a UDP socket to a port (cp) allocated by the host OS. From that port it will send a UDP packet containing the destination ap_name to server_host:lp and wait for a response. Upon reception of a packet on server_host:lp, the shim_IPCP creates a UDP socket for the flow with a port set by the host os (sp), binds to it and echoes the received datagram back from server_host:sp to client_host:cp. It will also notify the IRMd of an incoming flow allocation request IRM_MSG_CODE__IPCP_FLOW_REQ_ARR, with as src_ap_name ("John Day"). It will get the port_id as a return value of that message and create a flow with status FLOW_PENDING with that port_id. If the server responds negatively to the flow allocation request (i.e. the shim IPCP on the server side receives a IRM_MSG_CODE__IPCP_FLOW_ALLOC_RESPONSE with a response != 0, it will delete the pending flow. If response == 0, it will set the status to FLOW_ALLOCATED. On the client machine the IPCP will learn sp upon reception of the echoed datagram. It will then create a flow with the port_id it received with the message from the IRMd and set it to ALLOCATED. Pending implementation: DNS support, this PR only supports local flows on the loopback adapter 127.0.0.1. A thread to listen for the echoed message, to avoid the entire IPCP to block when the echoed message is lost. This PR compiles but is untested pending necessary implementations elsewhere in the stack.
