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: Pass qosspec at flow allocation

2018-10-05T07:07:47Z

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

lib: Make UNIX socket buffer size configurable

2018-05-03T10:26:48Z

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

lib: Use sequenced datagrams with UNIX sockets

2018-03-13T16:08:52Z

The UNIX sockets were using SOCK_STREAM, which does not preserve the message boundaries. This switches to SOCK_SEQPACKET. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

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, ipcpd, irmd: Fix several memleaks

This fixes several memleaks as reported by valgrind. It also fixes some calls to close() with -1.
