The close_on_exit call is removed and SDUs are cleaned up by the application in the ap_fini() call. This required a non-blocking peek() operation in the shm_ap_rbuff. Some initial implementation for future support of qos cubes has been added to the shm_rdrbuff. 2016-08-09T14:06:12+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-08-09T14:06:12+00:00 urn:sha1:9dce327e10bffddc9dc5058f06407e8ff12389b7 Fix missing set of api upon flow_alloc.

Timeouts can be specified. This requires the size of the rbuffs and du_map to be the same, to guarantee that when the shm_du_map is not full, the ap_rbuffs can't be full either. Added the timeout option to the flow for future use. 2016-08-02T22:29:34+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-08-02T22:19:06+00:00 urn:sha1:a6e8978fd9b5786607438689f8cd8b8efb8ef77e This adds a flow_select() call that will sleep until an SDU can be read on a flow. It returns the file descriptor for which an SDU is ready. It takes as optional argument a timespec struct to specify a timeout. 2016-07-29T11:58:38+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-07-28T19:15:17+00:00 urn:sha1:ce401448d62f65956ed57b077af2b315f59efe94 Various portability fixes for FreeBSD. POSIX requires shm file names to start with a "/" to be portable. lseek(2) can be undefined on POSIX shm, replaced with ftruncate(2). IRMd check on existing lockfile more portable. FreeBSD 11.0 is preferred as it natively supports robust mutexes. Full working LLC implementation pending. 2016-07-11T20:28:33+00:00 dimitri staessens dimitri.staessens@intec.ugent.be 2016-07-11T20:11:36+00:00 urn:sha1:e04defa422bd7d365d9d8389fde13e675e9783a2 Correct implementation of allocation for the Protocol Control Information. Also removes stale code checking for a corner case when the du map still wrapped multi-block SDU's.
