* lib: Make flow liveness timeout configurableDimitri Staessens2022-03-031-0/+2
| | | | | | | | | The qosspec_t now has a timeout value that sets the timeout value of the flow. Flows with a peer that has timed out will now return -EFLOWPEER on flow_read() or flow_write().

* lib, ipcpd, irmd: Wrap pthread unlocks for cleanupDimitri Staessens2021-06-231-6/+6
| | | | | | | | | | | | This add an ouroboros/pthread.h header that wraps the pthread_..._unlock() functions for cleanup using pthread_cleanup_push() as this casting is not safe (and there were definitely bad casts in the code). The close() function is now also wrapped for cleanup in ouroboros/sockets.h. This allows enabling more compiler checks.

* lib: Add per-message encryption with OpenSSLDimitri Staessens2019-08-031-2/+4
| | | | | | | | | | | | | | | | | | | This adds a per-message symmetric encryption using the OpenSSL library. At flow allocation, an Elliptic Curve Diffie-Hellman exchange is performed to derive a shared secret, which is then hashed using SHA3-256 to be used as a key for symmetric AES-256 encryption. Each message on an encrypted flow adds a small crypto header that includes a random 128-bit Initialization Vector (IV). If the server does not have OpenSSL enabled, the flow allocation will fail with an -ECRYPT error. Future optimizations are to piggyback the public keys on the flow allocation message, and to enable per-flow encryption that maintains the context of the encryption over multiple packets and doesn't require sending IVs.

* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-051-0/+35
| | | | | | | | | | | | The flow allocator now passes the full qos specification to the endpoint, instead of just a cube. This is a more flexible architecture, as it makes QoS cubes internal to the layers. Adds endianness transforms for the flow allocator protocol in the normal IPCP.

* lib: Make UNIX socket buffer size configurable0.11.3Sander Vrijders2018-05-031-4/+11
| | | | | | | | | | This makes the buffer size used by the UNIX sockets configurable. In case of a lot of IPCPs in the system it might become too small with the default value, resulting in irm command failures. The user can now easily configure it with an adequate value.

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-021-9/+9
| | | | | | | | | | | 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.

* build: Revise the build systemdimitri staessens2017-08-211-1/+0
| | | | | | | | | | 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, irmd: Implement flow allocation timeoutdimitri staessens2017-04-061-13/+1
| | | | | | Setting the timeouts on flow_alloc and flow_accept will now work. This makes some changes to the UNIX sockets used for management communication between the APs, IRMd and IPCPs.
* Change email addresses to ugent.beSander Vrijders2017-03-031-1/+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.
* build: Update licenses and copyrightdimitri staessens2017-01-091-10/+11
| | | | | Copyright is set to 2016 - 2017. License text on includes and sources in the library are changed to indicate the LGPLv2.1 license.
* ouroboros: Correct license statementsdimitri staessens2016-12-241-3/+2
| | | | | This corrects the license statements on all files. Installed headers are LGPLv2.1, the rest of the code is GPLv2.
* lib: Remove logs from stable sourcesdimitri staessens2016-12-031-19/+6
| | | | | This removes log output in applications and some size_t printf errors when compiling on 32 bit machines.
* lib: Stabilise flow allocationdimitri staessens2016-10-231-33/+0
| | | | | | | 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.
* build: Compile with strict conversiondimitri staessens2016-10-221-1/+0
| | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.
* lib, dev: Add asynchronous deallocationdimitri staessens2016-10-071-0/+33
| | | | | Flow deallocation from the application will immediately return (void call). The IRMd will not send a reply message.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-4/+2
| | | | | | | | | | | | IPCPs can now use ap_init() to initialize the memory. All flows are accessed using flow descriptors, this greatly simplifies IPCP development. Reverts the fast path to a single ap_rbuff per process. Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev holding tailored functions for shims. Moves the buffer_t to utils.h. Fixes the shim-eth-llc length field. Removes the flow from shared.h. Fixes #4 Fixes #5
* lib, irmd, ipcp: Add socket timeoutSander Vrijders2016-08-101-1/+15
| | | | | | This will add a timeout to the socket so that a process won't be blocked by the actions of the process with which it is communicating over the socket.
* lib: Fix cleanup for sending messagesdimitri staessens2016-08-091-17/+4
| | | | Cleanup handlers were not always popped.
* lib: sockets: Fix cancellation cleanupdimitri staessens2016-08-041-2/+13
| | | | | When cancelled in read() the fd should be closed and the allocated memory freed.
* ouroboros: Use ouroboros errno.hdimitri staessens2016-07-071-1/+1
| | | | | All includes of <errno.h> within ouroboros are replaced with the ouroboros errno.
* lib: Provide first implementation of revised CDAPSander Vrijders2016-07-051-3/+4
| | | | | | | | This commit introduces a first version of the revised CDAP specification. CACEP (for authentication purposes) has been separated from CDAP. Application developers may use CDAP if they find it useful. Within Ouroboros CDAP will be used to perform operations on the RIB of an IPCP.
* lib, irmd, ipcpd: Change pid to apiSander Vrijders2016-06-281-9/+9
| | | | Changes the variable name as well to API instead of PID.
* build: Change install directories and set correct permissionsSander Vrijders2016-06-201-1/+5
| | | | | | | | | This sets the correct install directories for all the binaries, library and header files. It also sets the right permissions on the sockets and shared memory so that regular users can also use the ouroboros library. Root privileges are required to run the irmd. Fixes #7
* lib, irmd, ipcpd: Flow deallocation over shim UDPdimitri staessens2016-05-211-0/+3
| | | | | | The shim UDP now supports deallocating a flow end-to-end. Contains some stability fixes for flow allocation and some missing close() calls in lib/sockets.
* ipcpd: initial IPC processesdimitri staessens2016-04-181-5/+2
| | | | | | | | | | | Basic functions for implementation of IPC processes, and implementation of core functions of the shim IPCP over UDP. Updates to the build system to compile these IPC processes, as well as some fixes in the irmd (rudimentary capturing exit signals) and some fixes in the library, mainly relating to the messaging. Basic implementation of creation / bootstrapping / deletion of the shim UDP. Placeholders for other functions.

| | | | | All messages sent to the IRMd now also get a reply back with the result of the operation.
* lib: Add ipcp_messages proto fileSander Vrijders2016-03-281-245/+0
| | | | | This removes the custom ser/des methods for communicating with the IPCP daemon and also uses GPB instead.
* lib, irmd: Use GPB for dev.c and IRMdSander Vrijders2016-03-281-411/+58
| | | | | IRMd and dev.c now also use GPB instead of our own ser/des. irm_msg struct has been dropped as well as the methods associated with it.
* lib: Update irm.h APISander Vrijders2016-03-281-0/+7
| | | | | | Removes rina_name_t from that API. Passing ap_name and api_id as params instead. The IRM tool has been updated accordingly. Some errors in the build related to protobuf-c have also been resolved.
* lib: Adds IRMd messages for the dev.h API callsSander Vrijders2016-03-241-33/+252
| | | | | | This adds several messages for the dev.h API calls to communicate with the IRM daemon. The deserializing of these messages is still missing and the irmd hasn't been updated with them either.
* lib: Add communication with IPCP daemonSander Vrijders2016-03-171-65/+281
| | | | | This adds the messages required for the IRMd to communicate with an IPC Process through the library.
* lib, irmd: Fix memleaksSander Vrijders2016-03-171-0/+1
| | | | | This removes some memleaks present in the sockets layer. It also fixes the bad initialization of the difs_size param in the irm_msg.
* lib: Add helpers for RINA namesSander Vrijders2016-03-111-22/+11
| | | | This adds helper functions for RINA names, to aid with handling them.

| | | | | common.h: dif_info renamed to dif_config missing struct fixed
* tools: Parse command line paramsSander Vrijders2016-03-021-1/+1
| | | | | This adds initial support to the irm tool for parsing command line parameters.
* lib, irmd, tools: Provide more IRM messagesSander Vrijders2016-03-011-83/+145
| | | | | | | This provides the other messages that are used to communicate between the library and the IRM Daemon. The IRM tool just calls the library right now to see if it works. A full fledged program will be provided in a next commit.
* lib: Add identifier for non-literal stringSander Vrijders2016-02-261-1/+1
| | | | | This adds the %s identifier in a sprintf. A non-literal was passed and used as a literal.
* lib: Fix two errorsSander Vrijders2016-02-261-1/+1
| | | | | | Fixes two errors in the library. The return code of a write to a socket was ignored. A non literal string was passed to sprintf as a literal one.
* lib, irmd: Address Dimitri's commentsSander Vrijders2016-02-261-19/+51
| | | | This addresses several comments Dimitri had on the sockets layer code.
* lib, irmd, tools: Support to create IPCPsSander Vrijders2016-02-251-0/+193
| | | | | | | Provides the initial support to create IPCPs via a command-line tool. It extends the socket layer with a message that is sent over a socket to the irmd when the irm_create_ipcp library function is called from a program.
