Removed the implementation of the rw_lock in favor of pthread_rwlock_t. Placeholder for the shm_du_map_sanitize function. 2016-06-14T12:05:28+00:00 Sander Vrijders sander.vrijders@intec.ugent.be 2016-06-05T14:49:32+00:00 urn:sha1:aeb53fcd725fe291afa6ffb683373c8e589afa64 This adds a shim over LLC over Ethernet. It uses the raw socket API to send messages directly over an interface. 2016-05-15T20:42:47+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-05-15T20:42:47+00:00 urn:sha1:3f5b31d49139968a84c42d5d3067d06edefa3aae 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. 2016-05-14T19:34:04+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-05-14T14:39:27+00:00 urn:sha1:037fec33cda726d0078e23798f462ad273153dd5 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. 2016-05-07T14:11:09+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-05-07T14:11:09+00:00 urn:sha1:eb9f44379d5316e7f7e9311d7a66d2041eca743a 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. 2016-04-27T16:36:31+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-04-27T16:36:31+00:00 urn:sha1:1a02682d0695509bb8255b2d10dee48c61d83c34 flow allocation now propagates on the client side up to the IPCP. added UNKNOWN_AP and UNKNOWN_AE definitions to dev.h 2016-04-20T10:39:50+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-04-20T10:36:53+00:00 urn:sha1:423cbd695b0eed9d4ec55abb1f6a0bfa0e4e48a4 fixes comments on 38c4169 (memleaks) 2016-04-19T08:04:20+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-04-19T07:42:42+00:00 urn:sha1:b2acd622d6380724fa16ee66b9f0f4463f1cd477 added missing NULL checks common argument check function for ipcps 2016-04-18T20:25:34+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-04-17T10:08:49+00:00 urn:sha1:21b304b46a347772c1338b22fba6a15291bb2945 Basic functions for implementation of IPC processes, and implementation of core functions of the shim IPCP over UDP. Updates to the build system to compile these IPC processes, as well as some fixes in the irmd (rudimentary capturing exit signals) and some fixes in the library, mainly relating to the messaging. Basic implementation of creation / bootstrapping / deletion of the shim UDP. Placeholders for other functions.
