For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common. 2017-09-30T15:58:18+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-30T15:58:18+00:00 urn:sha1:9405ad97e20686f74c06bcbac9523a8b4f10272e This makes the threadpool use pthread_cancel instead of setting an exit flag that threadpool managed threads check periodically. This drastically reduces CPU consumption in the irmd when running a lot of applications. It requires cancellation handlers in the ipcp and irmd to be implemented to ensure safe cancellation during operation and shutdown. 2017-09-29T13:12:36+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-27T13:33:39+00:00 urn:sha1:e3dba5812b1422a79e6e77ce9f923bade5a480e4 This adds the Loop-Free Alternates (LFA) policy. In case a link goes down a LFA may be selected to route the SDUs on without causing loops instead of the main hop that just went down. 2017-09-24T12:34:03+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-24T12:34:03+00:00 urn:sha1:ff5063ad0e7902ce59864a466bd9d8d606d788e4 This adds a threadpool manager to the DHT. This was needed because the detached thread could cause a data race on shutdown. The threadpool manager is revised to allow multiple instances in a single program. The irmd and ipcp now store commands in a buffer (list) instead of a single buffer before passing it to handler threads. 2017-09-23T10:32:07+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-23T10:27:23+00:00 urn:sha1:7ee95a3809aab3152837ceb5ffcd001ee9e83fde There was a return -1 in the allocate call which is unsafe since -1 may be a valid id in the bitmap. Since it's a data structure for internal use, I replaced the NULL checks with assertions. 2017-09-21T14:55:31+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-21T12:26:51+00:00 urn:sha1:f6071ecf0cd3768eaed9a847f676433c120ea89e This adds a PFF that returns an alternate hop as next hop in case the hop that would have been returned is down. 2017-09-20T12:16:34+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-20T11:56:17+00:00 urn:sha1:2c7e3030edb84abae14042f7a1a22b44255324be This turns the PDU Forwarding Function of the IPCP into a policy. For now only the simple PFF policy is available. 2017-09-19T16:46:13+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-19T15:47:26+00:00 urn:sha1:1dcef3957393c0500b81d93ffacf573e78be9a51 The DHT will now enroll or sync when a data transfer connection is added. This avoids the need to create a temporary data transfer connection during enrollment (and speeds it up considerably). The notifier system was modified to take an opaque pointer to the object that registers as a parameter. 2017-09-19T14:52:54+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-09-18T17:06:15+00:00 urn:sha1:541b1c5eeb5fe9f9aaa4aa6487852e5c59761139 This adds the flow down event to Ouroboros. In the shim-eth-llc, a netlink socket is opened which listens to device up/down events. For each event the flow is then adjusted with fccntl to notify the user the flow is down or back up again. In the normal IPCP an event is thrown if a write reports that the flow is down. 2017-09-18T07:27:53+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-09-18T06:03:31+00:00 urn:sha1:f86502516b2a069954d0529d8b43593ece7360eb This adds a virtual RIB that is accessible as a filesystem that is accessed through a fuse mountpoint (configurable , default is /tmp/ouroboros). Currently, each IPCP will export its link state database.
