Now it correctly tracks the number of outstanding requests or returns if it doesn't get a response for KAD_T_RESP seconds. This fixes multi-hop flow allocation over the normal. 2017-08-05T18:15:52+00:00 Dimitri Staessens dimitri.staessens@ugent.be 2017-08-05T18:15:52+00:00 urn:sha1:3f9fb4c957e639b96df672190c9d03eec02dce3e Upon flow_allocation, the IRMd queries IPCPs for the destination name. After this commit, when an IPCP allocates a flow, the IRMd won't query that IPCP. 2017-08-05T16:05:44+00:00 Dimitri Staessens dimitri.staessens@ugent.be 2017-08-05T16:05:44+00:00 urn:sha1:57784d85969a0bcf8599442e3be5ae7edf1fbe10 When a process was killed, ipcp_flow_dealloc was called under a lock, causing a deadlock in the IRMd because handling the IPCP response also needs to take the same lock (the IPCP calls flow_dealloc to finalize this). This deadlock also resulted in the IPCP always reporting that it failed to send a reply message as the deadlock effectively blocks the IRMd until its socket timeout expired and thus the IPCP was always responding to an already closed socket. 2017-08-05T15:15:17+00:00 Dimitri Staessens dimitri.staessens@ugent.be 2017-08-05T15:15:17+00:00 urn:sha1:ffd8de94c9b3829116f6604dfae8aa9a24ef2ef3 The commands towards the IPCPs have different time requirements, but the irmd had only a single timeout value to wait for a response. This commit allows setting different timeouts for the IRMd based on the command, configurable globally. 2017-08-04T10:30:33+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-08-04T10:30:33+00:00 urn:sha1:f85c70fdb6dbbadb903155120892e55b0eff5dda 2017-08-04T10:24:41+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-08-04T09:55:49+00:00 urn:sha1:0fe8d5aa50fcadc3b4eef65b2833944a76eb8f3e 2017-08-04T10:24:41+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-08-04T09:47:41+00:00 urn:sha1:055835e5b06d7f18d94ca1d6b2df5f0a3ec3e954 The blocking ipcp_query call was called under reg_lock, causing flow_allocs over the shim-eth-llc to block the irmd for prolonged timespans. 2017-08-03T17:33:00+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-08-03T17:33:00+00:00 urn:sha1:e77db148ce7adbaefb2ec7fb66a1fe0a36cff72f 2017-08-03T16:45:28+00:00 dimitri staessens dimitri.staessens@ugent.be 2017-08-03T16:45:28+00:00 urn:sha1:e3d19da0501bbb80ba1caf562ba61a99c63b10b7 This fixes pthread_condtimedwaits in the flow allocator of all IPCPs that had bad deadlines set (the interval instead of the actual absolute time). 2017-08-03T13:19:16+00:00 Sander Vrijders sander.vrijders@ugent.be 2017-08-03T12:51:41+00:00 urn:sha1:5bb3bea07b0ff38e4646ed6f835d9bdac6beced6 This adds a check for robust mutexes. The constant HAVE_ROBUST_MUTEX is set accordingly in config.h. It also adds some other fixes to make the prototype compile on the Hurd.
