ipcpd: Disable core lock by default

2021-06-21T06:45:53+00:00

This was beneficial on dual-XEON CPU systems, but on most hardware, this kills performance when running multiple IPCPs on a single CPU. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix buffer overflow in flow allocator RIB.

2021-06-21T06:45:50+00:00

Max value of UINT64 can be 20 characters when printed, need an extra byte for sprintf trailing '\0'. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix congestion window scaling

2021-06-21T06:45:42+00:00

This fixes scaling of the congestion window, which was a buggy mess. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Move RIB initialization to common ground

2021-06-21T06:45:25+00:00

This moves Resource Information Base (RIB) initialization into the ipcp_init() function, so all IPCPs initialize a RIB. The RIB not shows some common IPCP information, such as the IPCP name, IPCP state and the layer name if the IPCP is part of a layer. The initialization of the hash algorithm and layer name was moved out of the common ipcp source because IPCPs may only know this information after enrollment. Some IPCPs were not even storing this information. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix free of uninitialized variable in graph.c

2021-05-28T06:19:53+00:00

The new GCC 11.1 compiler discovered s_dist would be uninitialized with an unknown policy, so it doesn't need to be free'd. Also removes some unneeded includes in broadcast dt.c that I had pending. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Move connmgr and enrolment to common ground

2021-03-28T10:46:32+00:00

The connection manager and enrolment components of the unicast and broadcast IPCP have a lot in common, as conjectured in the paper. The initial implementation of the broadcast IPCP just duplicated the code. This moves the shared functionality to common ground. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Remove raptor IPCP

2021-03-28T10:46:05+00:00

This removes the raptor IPCP. The code hasn't been updated for a while, and wouldn't compile. Raptor served its purpose as a PoC for Ouroboros-over-Ethernet-Layer-1, but giving the extreme niche hardware needed to run it, it's not worth maintaining this anymore.

ipcpd: Don't include enroll.h in connmgr

2021-02-25T06:49:24+00:00

It's not needed to include enroll.h. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Single UDP port for the ipcpd-udp

2021-01-03T10:59:59+00:00

The UDP layer will now use a single (configurable) UDP port, default 3435. This makes it easer to allocate flows as a client from behind a NAT firewall without having to configure port forwarding rules. So basically, from now on Ouroboros traffic is transported over a bidirectional : UDP tunnel. The reason for not using/allowing different client/server ports is that it would require reading from different sockets using select() or something similar, but since we need the EID anyway (mgmt packets arrive on the same server UDP port), there's not a lot of benefit in doing it. Now the operation is similar to the ipcpd-eth, with the port somewhat functioning as a "layer name", where in UDP, the Ethertype functions as a "layer name".

build: Update email addresses

2021-01-03T10:57:05+00:00

The ugent email addresses are shut down, updated to Ouroboros mail addresses. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
