* irmd: Fix memleak when failing to list ipcpsDimitri Staessens2018-03-221-1/+1
| | | | | | | | | The list_ipcps call had a memleak in the failure case. Also fixes a compiler warning for a possible uninitialized variable and renumbers the gpb ipcpd message fields.

* lib: Simplify reg/unreg APIDimitri Staessens2018-03-2216-218/+662
| | | | | | | | | | | | | | | | | | | | The reg/unreg API is simplified to registering and unregistering a single name with a single IPCP. The functionality associated with registering names was moved from the IRMd to the irm tool. The function to list IPCPs was simplified to return all IPCPs in the system with their basic properties needed for management. The above changes led to some needed changes in the irm tool and the management functions that were depending on the previous behaviour of list_ipcps. Command line functionality to list IPCPs in the system is also added to the irm tool. Some older code was refactored.

* ipcpd: Add validity checks for eth-dixDimitri Staessens2018-03-121-1/+7

* ipcpd: Add IPCP over DIX EthernetDimitri Staessens2018-03-101-8/+32
| | | | | | | | | | | | | | | | | | This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.

* build: Allow out-of-tree build of toolsDimitri Staessens2018-02-141-1/+0
| | | | | | | | | | This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr.

* ipcpd: Revise Data Transfer component0.10.0Dimitri Staessens2018-02-136-55/+57
| | | | | | | | | | | This makes the TTL non-optional and allows the maximum (initial) value of the TTL to be specified at bootstrap (the default is set to 60). The fd in the DT PCI is now called EID (Endpoint ID). The names "dif" and "ae" have been replaced by "layer" and "component" respectively in all sources.

* ipcpd: Use the term "layer" and deprecate "shim"Dimitri Staessens2017-12-195-41/+41
| | | | | | | | | | | | | | This changes the terminology to use layer instead of DIF and deprecate the word "shim" for the IPCPs that attach to Ethernet LLC and UDP .The terminology has not yet been changed in the variable names etc. This reflects the design choices in Ouroboros to make IPCPs pure resource allocators instead of also providing an "IPC service". The Ouroboros IPCPs that attach to Ethernet and UDP implement the allocator and are thus not really shims.

| | | | | | | | | | | The raptor code is refactored to completely remove reduntant code relating to addresses. The dependency on the google protocol buffers is removed. The build system will only build raptor if the relevant kernel module is found on the system. The irm tool and the relevant documentation are updated.

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-0219-150/+165
| | | | | | | | | | | This refactors ouroboros to use "program" instead of "application process" and "process" instead of "application process instance" to align with current naming in current Operating Systems courses instead of the ISO nomenclature adopted by RINA. This change permeates through the entire implementation. Also contains some minor other refactors.

| | | | | | | | | | The binding of the normal IPCP to its name is moved from the source code to the irm tool introducing the "autobind" option for the bootstrap and enroll commands. With this option, the IPCP will be bound to the IPCP name and the DIF name automatically.

* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-141-1/+1
| | | | | | | | | | | | | | This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common.
* ipcpd: normal: Add Loop-Free Alternates routingSander Vrijders2017-09-291-23/+28
| | | | | | This adds the Loop-Free Alternates (LFA) policy. In case a link goes down a LFA may be selected to route the SDUs on without causing loops instead of the main hop that just went down.
* ipcpd: normal: Add alternate hop PFFSander Vrijders2017-09-211-35/+41
| | | | | This adds a PFF that returns an alternate hop as next hop in case the hop that would have been returned is down.
* ipcpd: normal: Make PFF policy-basedSander Vrijders2017-09-201-2/+12
| | | | | This turns the PDU Forwarding Function of the IPCP into a policy. For now only the simple PFF policy is available.

| | | | | The name parameter was not being matched correctly in ipcp connect and disconnect.
* tools: Add tool to connect IPCP componentsdimitri staessens2017-08-285-8/+206
| | | | | | | | | | | | 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 staessens2017-08-281-24/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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, lib, ipcpd, irmd: Add support for libgcryptdimitri staessens2017-08-091-9/+4
| | | | | | | | | | | | | | | | This adds support for libgcrypt. If at least version 1.7.0 of libgcrypt is present, it may be used for secure random number generation and is used for hashing in the irmd/ipcp. The hash definitions are moved to the internal hash.h header, and defined independently of the hashes that are defined as part of the directory policy for the normal IPCP. The translation is moved from the IRMd to ipcpd/ipcp.h. The bootstrap call from the IRMd expects the IPCP to return the correct hash algorithm with a dif_info struct, which is in line with the behavior of the enroll call. This also improves how some platform checks in the build system are handled.
* ipcpd, lib, irmd: Hardcode shim hash algorithmsSander Vrijders2017-07-121-39/+42
| | | | | | | This will hardcode the shim hash algorithms as they don't have an enrollment phase. Fixes #44
* ipcpd: normal: Make routing a policySander Vrijders2017-05-151-13/+21
| | | | | | This makes the routing component into a policy since different approaches may exist to do this, depending on how high the rank of the DIF is.
* ipcpd: Allow specifying fixed syntaxdimitri staessens2017-05-151-85/+52
| | | | | | This commits adds the functions and messages to specify a fixed protocol syntax during CACEP. It also revises the messages for specifying the DT protocol syntax from the irm tool.
* ipcpd: Allow specifying the hash algorithm to usedimitri staessens2017-04-161-42/+71

* lib, ipcpd, irmd: Register hash instead of namedimitri staessens2017-04-131-4/+8
| | | | | | | | | 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.
* Change email addresses to ugent.beSander Vrijders2017-03-0319-46/+84
| | | | | | | 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.

* ipcpd, lib: Revise normal IPCPdimitri staessens2017-02-061-1/+10
| | | | | | | | | | This PR updates the normal IPCP to use the new RIB. The old ribmgr is removed and replaced by a stub that needs to be implemented. All components (dir, fmgr, frct) were adapted to the new RIB API. A lot of functionality was moved outside of the ribmgr, such as the addr_auth, which is now a component of the IPCP. The address is also stored to the ipcpi struct. The irm tool has an option to set the gam policy of the rib manager.
* ipcpd: normal: Create policies for GAMSander Vrijders2017-01-121-2/+11

* | ipcpd: Let IPCPs bind a nameSander Vrijders2017-01-093-9/+3
|/ | | | | | | This allows IPCPs to bind a name, so that they can announce their name to neighbors which can then allocate a flow to them. Registering of the name happens by an administrator. It also moves the irmd_api to common ground, since it is used by all IPCPs.
