*	build: Allow older OpenSSL versions for random	Dimitri Staessens	2019-10-05	1	-0/+1
\| \| \| \| \| \| \| \| \|	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 <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
*	lib: Add per-message encryption with OpenSSL	Dimitri Staessens	2019-08-03	1	-0/+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: Set independent size for rbuff	Dimitri Staessens	2019-04-06	1	-0/+1
\| \| \| \| \| \| \| \| \| \|	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.

*	build: Update copyright to 2019	Dimitri Staessens	2019-02-05	1	-1/+1

*	lib: Split error checking from FRCT	Dimitri Staessens	2018-10-05	1	-0/+1
\| \| \| \| \| \| \| \|	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 <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
*	include, src: Update copyright to 2018	Dimitri Staessens	2018-01-09	1	-1/+1

*	lib, tools: Rename application process and instance	Dimitri Staessens	2017-12-02	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \|	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.

*	lib: Re-enable multi-block support	dimitri staessens	2017-10-13	1	-0/+1
\| \| \| \| \| \|	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	dimitri staessens	2017-09-18	1	-2/+5
\| \| \| \| \| \| \|	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.
*	lib: Fix check for robust mutexes	Sander Vrijders	2017-08-22	1	-2/+2
\| \| \| \| \|	There was an else clause matched with the wrong if statement, resulting in robust mutexes being enabled even in glibc 2.25.
*	build: Revise the build system	dimitri staessens	2017-08-21	1	-0/+57
	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.
