lib: Return number of written bytes on flow_write

2020-03-15T13:30:58+00:00

This is more in line with the write() system call and prepares for partial writes. Partial writes are disabled by default (and not yet implemented). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Change return type of fevent to ssize_t

2020-03-15T13:26:49+00:00

The return type was still an int, but since it returns the number of events, it should be an ssize_t. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irm: Revise naming API

2020-03-15T13:20:38+00:00

This revises the naming API to treat names (or reg_name in the source) as first-class citizens of the architecture. This is more in line with the way they are described in the article. Operations have been added to create/destroy names independently of registering. This was previously done only as part of register, and there was no way to delete a name from the IRMd. The create call now allows specifying a policy for load-balancing incoming flows for a name. The default is the new round-robin load-balancer, the previous behaviour is still available as a spillover load-balancer. The register calls will still create a name if it doesn't exist, with the default round-robin load-balancer. The tools now have a "name" section, so the format is now irm name ...

ouroboros: Rename service to ouroboros

2020-03-14T14:39:07+00:00

The service was called "irmd", but it makes a bit more sense to give it the system name. Only the service name is changed, the irmd binary remains irmd. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

doc: Remove pff option from irm man page

2020-02-16T17:21:52+00:00

The pff option was removed from irm tool in favor of selecting it from the routing policy. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

doc: Update manpage for binding

2020-01-18T11:10:42+00:00

The manpage mentions that bind works for programs, but not specify that these must be Ouroboros native programs. This is now added. 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.

doc: Update documentation to new website URL

2019-03-18T10:09:32+00:00

The documentation and package point to the imec site, which is now moved to ouroboros.rocks Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Revise UDP IPCP

2019-03-18T10:09:31+00:00

The UDP IPCP now uses a fixed server UDP port (default 3435) for all communications. This allows passing firewalls more easily since only a single port needs to be opened. The client port can be fixed as well if needed (default random). It uses an internal eid, so the MTU of the UDP layer is reduced by 4 bytes, similar to the Ethernet IPCPs.
