* ipcpd: normal: Add timerwheel to RIB managerSander Vrijders2016-11-281-81/+219
| | | | | | | The RIB manager now keeps track of ROs it has already received. The identification of a RO it knows is kept in a struct ro id. For the deletion of these RO ids, a timerwheel to the RIB manager. It also deletes ROs if they have a specified timeout.
* ipcpd, lib: Fix timerwheel issues / time_utilsdimitri staessens2016-11-253-21/+31
| | | | | | | Timerwheel would skip some additions due to a missed wakeup signal. Addition of timespecs and timevals in the time utilities would overflow tv_nsec/tv_usec if the sum is an integer number of seconds.

| | | | | | This adds a syntax version to the protobuf files. The latest version of protobuf otherwise complains that it is missing. The GPL license is also added on files where it was missing.

| * ipcpd: normal: Add syncing of RIB objectsSander Vrijders2016-11-194-392/+798
| | | | | | | | | | This adds the remote syncing of RIB objects. Subscribers are notified upon receipt of new/deleted/updated RIB objects.
* | tools: Use busy waiting in operfdimitri staessens2016-11-192-4/+24
| | | | | | | | | | | | Using nanosleep in between sending SDUs is not accurate enough when sending thousands of SDUs per second. The --sleep option is added for lowering CPU consumption in low bandwidth tests.
* | ipcpd: Fix SDU size check in LLC shimdimitri staessens2016-11-181-1/+1
| | | | | | | | Total SDU size (including LLC header) cannot exceed 1500 bytes.
* | lib: Remove dst_api field from rdrbuff blocksdimitri staessens2016-11-174-189/+137
| | | | | | | | | | | | Now that we have an rbuff per flow per AP, there is no more need to keep the dst_api in the rdrbuff. This also simplifies the sanitizer in the irmd.
* | irmd: Refactor irm_flowdimitri staessens2016-11-163-86/+48
| | | | | | | | | | Creation and destruction of the rbuffs is now completely handled in the irm_flow.

* | | irmd: Fix shutdowndimitri staessens2016-11-161-1/+0
| |/ |/| | | | | | | The IRMd should not send messages to the IPCPs after its mainloop terminated. IPCPs should cleanup al state when they get the SIGTERM.
* | ipcpd: normal: Add RIB objectsSander Vrijders2016-11-153-6/+587
|/ | | | | This adds the ability to create/update/destroy RIB objects. Syncing with other DIF members is not yet supported.
* lib: Simplify CDAP APISander Vrijders2016-11-013-209/+129
| | | | | | This will simplify the CDAP API. Now the opcode has to be given when sending a CDAP request. Before a separate operation was provided since some of the function parameters are unused for certain commands.

| * ipcpd: normal: Add policy for obtaining a flat addressSander Vrijders2016-11-0113-19/+269
| | | | | | | | | | | | This adds a policy for obtaining a flat address, and thus also the infrastructure for policies in the IPCP. The IPCP should check if the address is available; this is currently not there yet.
* | lib, ipcpd: Improve flow allocationdimitri staessens2016-10-315-141/+168
| | | | | | | | | | | | | | All calls for opening rbuffs are now concentrated on the dev side. This allows some simplifications in the np1 calls. The ipcp_fini call will not destroy the mutex associated with the state, since the final state needs to be checked before shutting down an IPCP.

| | | | | | | | | | Fixes a double free (conf->dif_name) and the handling of non-created threads when the bootstrap of an IPCP fails
* | tools: Add operf tooldimitri staessens2016-10-305-0/+628
| | | | | | | | | | | | This tool allows bidirectional bandwidth measurement between a client and server application. The server reflects all traffic back to the client. The traffic can be capped at a certain rate or set to flood.

| | | | | | | | | | | | Flow_event_wait will either return -EINVAL, -ETIMEDOUT or a positive integer indicating the number of SDUs in the fqueue. This allows to call the function as the condition for a non-terminating while loop.

| | | | | | | | | | | | | | | | | | If alloc_res fails all resources will be cleaned, except for the assigned flow_descriptor, which must be released with a dealloc call. Calling dealloc after a failed flow_alloc will not try to destroy the already cleaned up flow in the IRMd and IPCPs. Also fixes some memleaks in the oping client.

* lib, ipcpd: Further stabilization of flowsdimitri staessens2016-10-268-183/+92
| | | | | | | | | | | The steps for flow deallocation have been further refined. An operation ipcp_flow_fini() which wait for all SDUs to be read from a flow has been added. The shim IPCPs and the local IPCP have been adapted to this new API. Deallocation messages have been removed from the shim IPCPs, since there is insufficient state synchronisation between them to make this work reliably.

| | | | | | | | | | | | A check was missing in the shim UDP if the destination was already present in the directory, in which case no further queries were needed.

| | | | | | | | | | | | | | This adds a threadpool for the main loop of the IPCPs. Before there was a single thread handling each request, which could result in starvation since performing name queries at the same time as enrolling a normal IPCP was impossible.

| * | lib, irmd, ipcpd: Add name querying to IPCPsSander Vrijders2016-10-2615-276/+604
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to query IPCPs if a name can be reached through them, e.g. if a name is available in a DIF. This means that in the shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like query has been added, in the local a check is done to see if the name is registered, and in the normal currently no application is reachable through it.
* | | irmd: Add log messages for flow allocationdimitri staessens2016-10-261-2/+9
| | | | | | | | | | | | | | | | | | In the rewrite of the flow allocator for per-port ring buffers, the messages were removed because they were not accurate anymore. This adds messages when a port is allocated.
