build: Allow older OpenSSL versions for random

2019-10-05T11:52:26Z

Ubuntu 16 comes with older versions of OpenSSL, glibc and libgcrypt. Ouroboros will now fall back to OpenSSL even if the version is <= 1.1.0. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add per-message encryption with OpenSSL

2019-08-03T10:10:57Z

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: Set independent size for rbuff

2019-04-06T11:40:52Z

This allows setting the size of the rbuffs in a system independently of the main packet buffer using SHM_RBUFF_SIZE. The benefit of setting a smaller rbuff size is that a single process can't fully occupy the main packet buffer. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Split error checking from FRCT

2018-10-05T16:08:25Z

This splits off the CRC from FRCT so it can be set independently. Ouroboros now allows raw flows with error checking. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib, tools: Rename application process and instance

2017-12-02T13:56:20Z

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. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Re-enable multi-block support

2017-10-13T08:03:47Z

Multi-block support was forgotten during the update of the build system. This enables it again and fixes some bugs when it is disabled and larger SDUs are sent.

lib: Provide RIB API to export internals via fuse

2017-09-18T07:27:53Z

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.
