* ipcpd: normal: Fix release buildSander Vrijders2016-12-021-0/+1
| | | | | The release build failed since an assert was optimized out, which resulted in a unused variable error.
* 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.
* ipcpd, lib: Fix timerwheel issues / time_utilsdimitri staessens2016-11-252-19/+29
| | | | | | | 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.
* ipcpd: Add timerwheeldimitri staessens2016-11-255-2/+508
| | | | | The timerwheel can be used to defer work to a certain timeslot in the future.
* ipcpd, lib: Add syntax version to protobuf filesSander Vrijders2016-11-225-0/+125
| | | | | | 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.
* | ipcpd: Fix SDU size check in LLC shimdimitri staessens2016-11-181-1/+1
|/ | | | Total SDU size (including LLC header) cannot exceed 1500 bytes.

| | | | | This adds the ability to create/update/destroy RIB objects. Syncing with other DIF members is not yet supported.
* lib: Simplify CDAP APISander Vrijders2016-11-012-84/+61
| | | | | | 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 Vrijders2016-11-0110-15/+252
| | | | | | | | | | | | 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 staessens2016-10-314-50/+74
| | | | | | | | | | | | | | 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.

* | ipcpd: Clean shutdown when bootstrap failsdimitri staessens2016-10-314-28/+46
|/ | | | | Fixes a double free (conf->dif_name) and the handling of non-created threads when the bootstrap of an IPCP fails
* ipcpd: normal: Fix bugs in connection establishmentSander Vrijders2016-10-274-46/+58
| | | | This fixes some bugs in connection establishment over the normal IPCP.

* lib, ipcpd: Further stabilization of flowsdimitri staessens2016-10-265-145/+18
| | | | | | | | | | | 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.
* ipcpd: shim-udp: Add check for directory entrySander Vrijders2016-10-261-0/+5
| | | | | | 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.

| * ipcpd: Add threadpool for main loopSander Vrijders2016-10-262-31/+49
| | | | | | | | | | | | | | 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 Vrijders2016-10-269-172/+520
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | Remote requests for a flow that's locally deallocated should not generate an error. Sending messages should not be under lock.

* | lib: Stabilise flow allocationdimitri staessens2016-10-231-0/+1
|/ | | | | | | Deallocation was reverted to a synchronoous operation between the AP, IRMd and IPCP in order to avoid inconsistent states of the port_id. Fixes some memory leaks, particularly the shm_flow_set is now closed upon deallocation.
* dev, ipcp: Fix setting default flow optionsdimitri staessens2016-10-231-9/+2
| | | | | The default flow options were not set when a flow allocation request arrives remotely. This went unnoticed due to a previous bug.
* build: Remove the gethostbyname checkdimitri staessens2016-10-231-17/+0
| | | | | gethostbyname is included in POSIX 2001. Ouroboros requires at least POSIX 2001 and recommends POSIX 2008 for stable builds.

| * lib: Demultiplex the fast pathdimitri staessens2016-10-215-143/+264
| | | | | | | | | | | | | | | | The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API.
* | ipcpd: normal: Avoid allocating flow over unenrolled IPCP.Sander Vrijders2016-10-171-0/+10

* lib, dev: Implement read/write options for flowsdimitri staessens2016-10-161-0/+2
| | | | | | | Added the missing implementation of setting read/write options for flows. This allows applications to block the fast path for remotes. IPCPs can use this to block the fast path for the N + 1 flow when receiving remote deallocation requests.

* ipcpd: normal: Improve upon the internal designSander Vrijders2016-10-1211-574/+411
| | | | | | | | This commit will remove the RMT component from the normal IPCP, as some of its functionality would else be duplicated in the FMGR. Now all reading from flows, either N-1 or N+1 is done in the FMGR, then either passed to the FRCT or a lookup is performed in the PFF (not there yet) and the PDU is forwarded.
