* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-2132-931/+1798
| | | | | | | | | | | | | | | | | | | | | | The complete data model inside the IRMd has been restructured. The bind operation was revised to allow binding of AP and AP instances and register those names with different DIFs (see "irm bind" for details). Server applications require to call ap_init with a server name argument, client application that do not the be reachable over any DIF can call ap_init(NULL). Calling ap_init for a client with a specified name will not have adverse consequences for the application, but will consume unnecessary resources in the IRMd. Application servers can now be started at any point after the IRMd has been started. Starting servers, binding AP names and registering names in DIFs can be performed in any order that does not defy temporal logic. Supports naming instances by their pid. In case of IPCP Instances created with the IRM tool, the name assigned during "irm ipcp create" can be used. All the changes required updates in the tools.
* ipcpd: normal: Handle enrollment repliesSander Vrijders2016-08-195-74/+155
| | | | | | | | This adds a condition variable with a timeout to the CDAP request so that we can respond correctly to the answer from the remote. It also adds a timeout to the condition variable waiting on completion of enrollment. Furthermore, for every CDAP callback a new thread is now spawned, to avoid deadlocking in case a callback is stuck.
* ipcpd: shim-udp: Change nsupdate and nslookup checkSander Vrijders2016-08-161-28/+17
| | | | | | | Previously it was up to the admin to choose whether or not to enable DDNS. Now the build just checks if the executables can be found, and if they are available DDNS functionality is enabled, else it is disabled.
* ipcpd: Fix bootstrap with api_binddimitri staessens2016-08-125-10/+27
| | | | | Calling api_bind during bootstrap caused the IRMd to lock up. api_bind is now called after the normal completes bootstrapping.
* ipcpd: Add condition variable to IPCP stateSander Vrijders2016-08-118-230/+235
| | | | | | | This adds a condition variable to the IPCP state, so that upon state changes any listeners to state changes can be notified. It also replaces the read/write lock with a mutex in order to be able to do so.

* | tools: irm: Create IPCP upon enroll if unexistingSander Vrijders2016-08-112-2/+11
|/ | | | | This will create a new IPCP if enroll is called on a non existing IPCP. It also fixes two memleaks.
* ipcpd: Put correct max SDU length in shim-eth-llcSander Vrijders2016-08-111-22/+7
| | | | | Now the correct max length of an SDU is checked upon writing a frame, as well as on receiving it.

| * lib, irmd: Bind AP instances to AP_subsetsdimitri staessens2016-08-1010-30/+316
| | | | | | | | | | | | | | This call will allow grouping AP instances of a certain AP together which are configured identically. Adds the bind operation to dev and updates the applications to make use of this call. Flow_alloc is now only called with the pid and doesn't send the apn anymore.
* | ipcpd: Add MSG_DONTWAIT flag to shim-eth-llcSander Vrijders2016-08-101-1/+1
| | | | | | | | | | | | This adds the MSG_DONTWAIT flag to the send function of the shim-eth-llc, when using PF_PACKET. Previously the send would return only after the frame was sent, resulting in poor performance.
* | lib, irmd, ipcp: Add socket timeoutSander Vrijders2016-08-105-12/+43
|/ | | | | | This will add a timeout to the socket so that a process won't be blocked by the actions of the process with which it is communicating over the socket.

| | | | | | | | | | | | | | | | | | This will notify the IRMd when the IPCP is initialized and ready to receive messages. Previously a bootstrap could fail since the IPCP was not listening to the socket yet.

| |\ \ | | | | | | | | | | | | Several small fixes and enhancements
| | * | tools: irm: Create IPCP on bootstrap if unexistingSander Vrijders2016-08-101-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | If the admin tries to bootstrap an IPCP that does not yet exist, it will first create the IPCP, then bootstrap it since it has all required information.
| | * | irmd: Remove IPCP from list upon errorSander Vrijders2016-08-101-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If an IPCP crashes (due to a segfault for instance), it is removed from the spawned apis list. However, if it was an IPCP it should also be removed from the IPCPs list, since else on shutdown, the irmd will try to destroy the IPCP that crashed.
| | * | ipcpd: Fix locking problem in local IPCPSander Vrijders2016-08-101-2/+2
| | |/ | | | | | | | | | | | | A lock was not being taken to check the state, but then it was released if the state was not IPCP_NULL, resulting in a segfault.
* | / irmd: Graceful shutdowndimitri staessens2016-08-105-80/+82
|/ / | | | | | | | | | | Threads from the threadpool will now check the state of the IRMd and exit gracefully without a need to cancel them. This avoids the unsafe call of pthread_cancel in the signal handler.

| | | | | | This adds the functionality of exchanging the static DIF information between 2 DIF members. After exchange the enrollment is stopped, and the IPCP that initiated enrollment transitions to the enrolled state.
* lib, tools: Add POSIX version to source filesSander Vrijders2016-08-083-0/+4
