| * ipcpd: normal: Address review commentsSander Vrijders2016-12-024-29/+35
| | | | | | | | This addresses some comments after a code review by Dimitri.
| * ipcpd: Split IPCP state PENDING_ENROLSander Vrijders2016-11-308-90/+136
| | | | | | | | | | | | | | | | This will split the IPCP state PENDING_ENROL into IPCP_CONFIG and IPCP_BOOTING. IPCP_CONFIG is concerned only with configuring the IPCP with the bare essence. When in IPCP_BOOTING, the IPCP will complete its configuration by starting its policies, and thus making the IPCP completely functioning.
| * ipcpd: normal: Add helper functions for pathnamesSander Vrijders2016-11-295-16/+138
| | | | | | | | | | This adds some helper functions to construct pathnames. Users of the RIB manager may find these handy when constructing RIB objects.
| * ipcpd: normal: Change ro_attr initializationSander Vrijders2016-11-293-144/+109
| | | | | | | | | | | | | | This changes the way RIB object attributes are set. Previously the struct was called ro_props and it had to be allocated on the heap. Now it follows the model of pthreads closely. This commit also changes the callbacks of the RO subscribers to return void instead of int.
| * ipcpd: normal: Complete flat address policySander Vrijders2016-11-296-77/+276
| | | | | | | | | | This will add a check in the flat address policy to see if the address is in use or not.

| * 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.

|/ | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

|/ / | | | | | | | | | | 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.

|/ | | | | | 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.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | 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.
