* doc: Remove pff option from irm man pageDimitri Staessens2020-02-161-6/+0
| | | | | | | | The pff option was removed from irm tool in favor of selecting it from the routing policy. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* doc: Update manpage for bindingDimitri Staessens2020-01-181-1/+2
| | | | | | | | The manpage mentions that bind works for programs, but not specify that these must be Ouroboros native programs. This is now added. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>

* lib: Add per-message encryption with OpenSSLDimitri Staessens2019-08-031-0/+3
| | | | | | | | | | | | | | | | | | | 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.

* ipcpd: Revise UDP IPCPDimitri Staessens2019-03-181-0/+12
| | | | | | | | | | | The UDP IPCP now uses a fixed server UDP port (default 3435) for all communications. This allows passing firewalls more easily since only a single port needs to be opened. The client port can be fixed as well if needed (default random). It uses an internal eid, so the MTU of the UDP layer is reduced by 4 bytes, similar to the Ethernet IPCPs.

* ipcpd, lib, irmd, tools: Change SDU to packetSander Vrijders2018-10-051-1/+1
| | | | | | | | This will change SDU (Service Data Unit) to packet everywhere. SDU is OSI terminology, whereas packet is Ouroboros terminology. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* lib: Simplify delta-t logicDimitri Staessens2018-06-051-2/+0
| | | | | | | | | | This revises the delta-t implementation to align with Watson's timer specifications. FRCT will never deliver out-of-order packets. A raw flow (without delta-t state machine) will be able to provide such a service. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Add event types to fqueueDimitri Staessens2018-05-141-3/+28
| | | | | | | | | | | The event type of the current event in the fqueue can now be requested using the fqueue_type() command. Currently events for packets (FLOW_PKT), flows (FLOW_UP, FLOW_DOWN) and allocation (FLOW_ALLOC, FLOW_DEALLOC) are specified. The implementation only tracks FLOW_PKT at this point.

* lib: Simplify reg/unreg APIDimitri Staessens2018-03-221-4/+11
| | | | | | | | | | | | | | | | | | | | 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.

* lib: Allow disabling partial readDimitri Staessens2018-03-192-3/+4
| | | | | | | | | | | | | | This allows disabling partial reads. It adds a flag FLOWFRNOPART that disables partial reads. Partial read is different from partial delivery (FRCTFPARTIAL), which allows delivery of fragments of an incomplete packet and thus potentially corrupted data. FLOWFRNOPART will never deliver corrupted data (unless FRCTFPARTIAL is also set). If FLOWFRNOPART is set and the buffer provided to flow_read is too small for the SDU, that SDU will be discarded and -EMSGSIZE is returned; Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* lib: Allow partial readDimitri Staessens2018-03-121-1/+5
| | | | | | | | | | | | | This implements partial read of packets if the buffer supplied to flow_read() is smaller than the packet in the buffer. If the number of bytes returned by flow_read equals the size of the buffer, the next read() will deliver the next bytes of the packet (or 0 if the packet was exactly the size of the buffer on the previous read). Implements #7. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Add IPCP over DIX EthernetDimitri Staessens2018-03-101-5/+30
| | | | | | | | | | | | | | | | | | 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.

* lib: Add fccntl operation to get queue lengthsDimitri Staessens2018-02-281-1/+7
| | | | | | | | | | This adds the FLOWGRXQLEN and FLOWGTXQLEN operations to fccntl to get the number of packets that are in the receive and transmit buffers respectively. The flow statistics are updated to show these queue lengths. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* ipcpd: Revise Data Transfer component0.10.0Dimitri Staessens2018-02-131-2/+2
| | | | | | | | | | | 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.

* build: Use GNUInstallDirs instead of hardcoded values0.9.9Sander Vrijders2018-02-061-1/+1
| | | | | | | | This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders <[email protected]>

* ipcpd: Use the term "layer" and deprecate "shim"Dimitri Staessens2017-12-193-65/+60
| | | | | | | | | | | | | | 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.

* lib, tools: Rename application process and instanceDimitri Staessens2017-12-024-33/+31
| | | | | | | | | | | 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.

* ipcpd: Don't bind from the IPCPDimitri Staessens2017-11-291-3/+6
| | | | | | | | | | 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. Signed-off-by: Dimitri Staessens <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
* dev: Split nonblocking read and writeDimitri Staessens2017-10-301-1/+5

| | | | | | | | | This adds user documentation for the Ouroboros User Manual in man sections 7 and 8. It consists of a general man page, a tutorial and a glossary. It also fixes and updates other manpages in the Ouroboros Programmer's Manual.
* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-148-79/+6
| | | | | | | | | | | | | | 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.
* doc: man: Update fccntl manpageSander Vrijders2017-09-191-0/+2
| | | | | The option to mark a flow as down was missing from the manpage of fccntl.
* ipcpd, lib: Add flow down eventsSander Vrijders2017-09-191-0/+3
| | | | | | | | 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: Add fccntl configuration commanddimitri staessens2017-08-313-2/+120
| | | | | | | 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".

| | | | | | | | | | 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.
