lib: Move protobuf definitions to pb/ directory

2023-08-30T15:11:41+00:00

This moves the protobuf definition in the library to a pb/ directory. Also renames the protobuf files and does a quick review of the #define guards in the include library to specify _LIB_ for internal/non-public library headers. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Remove semicolon after protobuf messages

2023-03-18T16:12:26+00:00

Doesn't seem to be needed, this makes it uniform in all protobuf files. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Make flow liveness timeout configurable

2022-03-03T11:00:54+00:00

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

lib: Add per-message encryption with OpenSSL

2019-08-03T10:10:57+00:00

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.
