* lib: Make flow liveness timeout configurableDimitri Staessens2022-03-031-8/+9
| | | | | | | | | 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: Add per-message encryption with OpenSSLDimitri Staessens2019-08-031-0/+1
| | | | | | | | | | | | | | | | | | | 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/+33
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 <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
