* lib: Get RIB attributes from componentDimitri Staessens2018-02-201-23/+47
| | | | | | | | | | | | This revises the RIB so it gets the complete file attribute list from the component instead of setting some attributes in the library. This will allow setting read/write access later on in the component itself. The time of last change of lsdb entries in the file system is now set to the time of the last received Link State Update for that entry.

* lib: Use correct names for st_modes in RIBDimitri Staessens2017-11-101-6/+8
| | | | | | | | | The RIB implementation was using internal variables from the linux implementation instead of the POSIX defined macros. The POSIX defined macros require defining __USE_XOPEN to access them. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Pass the fuse struct to the handling threaddimitri staessens2017-09-211-4/+2
| | | | This avoids potential data races on rib.fuse.
* ipcpd: Fix shutdown of ribdimitri staessens2017-09-201-0/+3
| | | | Fixes #50
* lib: Provide RIB API to export internals via fusedimitri staessens2017-09-181-0/+389
| | | | | | | 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.
* ipcpd: Revise internals of normal IPCPdimitri staessens2017-09-121-1431/+0
| | | | | | | | 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.
* lib, ipcpd, irmd: Fix bugs reported by static analysisSander Vrijders2017-08-291-1/+3
| | | | This fixes several bugs as reported by the clang static analyzer.
* ipcpd: Deprecate gam as autonomous componentdimitri staessens2017-08-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* build: Revise the build systemdimitri staessens2017-08-211-1/+4
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.

* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-10/+14
| | | | | | | | | All information passed over the IRMd/IPCP boundary for using IPC services (flow allocation, registration) is now hashed. This effectively fixes the shared namespace between DIFs and the IRMDs. This PR also fixes some API issues (adding const identifiers), shuffles the include headers a bit and some small bugs.
* lib: Fix list_move on wrong listSander Vrijders2017-03-281-3/+9
| | | | | | The list move was being done on the whole list of sub events, whereas it should only be done on the first entry. A cleanup handler was also added.
* lib, ipcpd: Fix bugs in ro setsSander Vrijders2017-03-281-1/+9
| | | | | This fixes several bugs in the ro sets, rib. And it fixes several bugs in the graph and routing component of the normal IPCP.
* Change email addresses to ugent.beSander Vrijders2017-03-031-2/+2
| | | | | | | Our mailserver was migrated from intec.ugent.be to the central ugent.be emailserver. This PR updates the header files to reflect this change as well. Some header files were also homogenized if the parameters within the functions were badly aligned.

* lib, ipcp: Correctly init condvarsdimitri staessens2017-02-091-1/+9
| | | | | The timerwheel and RIB use timedwaits. The condition variables are now correctly initialised to use the configuration defined clock.
* lib: Retrieve number of children of a RIB nodedimitri staessens2017-02-031-3/+10

* lib: Fix insertion order in RIBdimitri staessens2017-02-021-8/+13
| | | | | | | | The new element must be added before the larger element (list_add_tail, since it's a circular list). Also fixes a bug and improves the locking in rib_pack (rib must be locked until the subtree is fully packed in the buffer).
* lib: Add packing and unpacking RIBdimitri staessens2017-01-311-29/+252
| | | | | | | | | | | | | | | | | | | The rib_pack function allows packing a subtree of the RIB for dissemination. The options PACK_HASH_ROOT and PACK_HASH_ALL will add the hashes for the root object of the packed subtree or every object to the packed message respectively. Checking of the hashes is currently only performed at the top level object, verifying the complete operation. The rib_unpack function unpacks a packed message and inserts its contents in the RIB. The option UNPACK_CREATE flags that the unpack operation is allowed to create new objects, else it will only update existing objects. More advanced options could be added in the future. The packed message structure uses Google Protocol Buffers, as defined in ro.proto. It adds tests for these functions to the rib_test.
* lib: Add function to get children of node in RIBdimitri staessens2017-01-291-0/+67
| | | | | Returns the names of the nodes (not the full paths). The function allocates memory to the children pointer that should be freed.
* lib: Add new version of Resource Information Basedimitri staessens2017-01-211-0/+1097
The new RIB is implemented as a tree with doubly linked nodes (parents keep a link to each child, each child keeps a link to its parent). An index is kept in a btree using CRC32 hashes of the path name in the RIB. Nodes keep an SHA3-256 hash value that is unique for the entire subtree. This allows quick checks to see if two RIB subtrees are in sync. The event system for the RIB is based on the event system for flows (fqueue), but implemented completely in dynamic memory using linked lists. An initial test is performed for the RIB. This PR does not modify existing code to use the new RIB.
