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.

build: Set default number of threads in eth to 1

2019-03-05T08:10:38+00:00

This makes the eth packet handler single-threaded by default, at least until stability issues that seem to be related to multi-threading are fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Refactor create_r and flow_req_arr

2019-03-04T07:57:57+00:00

The API calls for the IPCP to inform the IRMd of IPCP creation and incoming flow request had the pid_t in the call. This pid_t is removed and the getpid() call is now placed inside the function. Also refactors the cleanup for the main() functions of some of the lower IPCPs. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Update copyright to 2019

2019-02-05T08:58:08+00:00

Updates the copyright notice in all sources to 2019. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix deallocating non-initialized np1 flows

2018-12-29T09:43:31+00:00

This fixes the deallocation of non-initialized IPCP flows. These can occur when some operations are not implemented. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

include: Add a flow_join operation for broadcast

2018-12-27T15:08:56+00:00

This adds a new flow_join operaiton for broadcast, which is a much safer solution than overloading destination name semantics. The internal API now also has a different IPCP_FLOW_JOIN operation. The IRMd doesn't need to query broadcasts IPCPs for the name, it can just check if an IPCP with the layer name exists. The broadcast IPCP doesn't need to implement the query proxy call anymore.

ipcpd: Wait for buffer when writing to Eth device

2018-12-08T09:08:07+00:00

This will cause the Ethernet IPCP to wait for a free buffer when using raw sockets to avoid packet drops when the network is congested. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix uninitialized value for ECN

2018-11-20T16:06:12+00:00

The ECN value in the packet was not set during write of a new packet. Also removes the outdated abstract syntax enum. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Add Explicit Congestion Notification field

2018-11-20T15:04:13+00:00

This adds an extra field to the data transfer PCI which can be used to flag congestion by intermediate routers. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add broadcast IPCP

2018-10-24T09:58:49+00:00

This adds a broadcast IPCP that allows us to easily create multicast applications. The broadcast IPCP accepts flows for ".mc". A tool, obc (Ouroboros broadcast), is added that sends and reads a message to a broadcast layer. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
