* ipcpd: Enroll DHT when creating dt connectiondimitri staessens2017-09-198-94/+148
| | | | | | | | | The DHT will now enroll or sync when a data transfer connection is added. This avoids the need to create a temporary data transfer connection during enrollment (and speeds it up considerably). The notifier system was modified to take an opaque pointer to the object that registers as a parameter.
* ipcpd, lib: Add flow down eventsSander Vrijders2017-09-198-105/+316
| | | | | | | | This adds the flow down event to Ouroboros. In the shim-eth-llc, a netlink socket is opened which listens to device up/down events. For each event the flow is then adjusted with fccntl to notify the user the flow is down or back up again. In the normal IPCP an event is thrown if a write reports that the flow is down.

* lib: Provide RIB API to export internals via fusedimitri staessens2017-09-187-18/+565
| | | | | | | This adds a virtual RIB that is accessible as a filesystem that is accessed through a fuse mountpoint (configurable , default is /tmp/ouroboros). Currently, each IPCP will export its link state database.
* lib: Add reordering queue to FRCTSander Vrijders2017-09-155-13/+331
| | | | | This adds a reordering queue to FRCT so that SDUs can be delivered in-order when requested.

| | | | | | This fixes output when detecting DDNS tools and homogenizes output and the APIs used to pass variables between the build system and the sources. Fixes some minor issues and typos).

| * ipcpd: Revise internals of normal IPCPdimitri staessens2017-09-1235-4111/+701
| | | | | | | | | | | | | | | | This removes the RIB as a datastructure and CDAP as the protocol between IPCPs. CDAP, the rib and related sources are deprecated. The link-state protocol policy is udpated to use its own protocol based on a simple broadcast strategy along a tree. The neighbors struct is deprecated and moved to the library as a generic notifier component.

* ipcpd: normal: Simplify enroll APISander Vrijders2017-09-015-12/+10
| | | | | | | This will remove the dst parameter from enroll_boot, since it was only being used in logging. It also turns some other debug logs into info logs, and makes the component names as they are used in logs all lowercase.

| | | | | | | | | | | | | | This replaces the flow_set_* commands with a single fccntl command that can configure flows and the FRCT instance. For more details, see "man 3 fccntl".
* | ipcpd: Add check if name was already registeredSander Vrijders2017-08-305-31/+20
| | | | | | | | | | This adds a check in the shims if a name was already registered, since it should not return an error.
* | irmd: Add specific timeout for IPCP connectSander Vrijders2017-08-303-0/+7
|/ | | | | | This adds a specific timeout for IPCP connect, since it may take a lot longer than the regular socket timeout due to flow allocations in the IPCP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The correct state was returned but not set internally in the lookup_struct, causing lookup_wait to return a lookup in LU_PENDING if the wait timedout. This also unlocks the IRMd during register calls and fixes some cleanup if lookup_wait gets interrupted. Fixes #48

| * tools: Add tool to connect IPCP componentsdimitri staessens2017-08-2823-61/+619
| | | | | | | | | | | | | | | | | | | | | | | | This enables user-written tools to instruct IPCPs to establish and tear down connections (a.k.a. adjacencies) between its internal components (Management and Data Transfer). For more info, do "irm ipcp connect" or "irm ipcp disconnect" on the command line. This commit exposes a deletion bug in the RIB where FSO's fail to unpack/parse. This will be fixed when the RIB is deprecated.
| * ipcpd: Deprecate gam as autonomous componentdimitri staessens2017-08-2838-1309/+864
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The graph adjacency manager has been deprecated in favor of providing an external interface into the connectivity manager so that adjacencies can be controlled from the command line, user scripts or user applications. The gam and its associated policies were removed from the normal IPCP and the IRM configuration tools. The "/members" part of the RIB was deprecated. Removal of the gam means that initial connectivity based on changes in the RIB can't be provided, so some changes were required throughout the normal IPCP. The enrollment procedure was revised to establish its own connectivity. First, it gets boot information from a peer by establishing a connection to the remote enrollment component and downloading the IPCP configuratoin. This is now done using its own protocol buffers message in anticipation of deprecation of the RIB and CDAP for communication within a DIF. After the boot information is downloaded, it establishes a data transfer flow for enrolling the directory (DHT). After the DHT has enrolled, it signals the peer to that enrollment is done, and the data transfer connection is torn down. Signaling connections is done via the nbs struct, which is now passed to the connmgr, which enables control of the connectivity graph from external sources.

| | | | | | | | | | | | | | The LLC shim was not being built even though it should be build. This is due to CMake behaviour that when you set a var in the parent scope, it is not set in the local scope. It also adds back THIS_TYPE to the shim-eth-llc.
