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.

irmd: Don't destroy shm_flow_set from IRMd

2019-03-12T08:18:51+00:00

The shm_flow_set for the processes are now created and destroyed together with the irm_flow objects. This old code causes stack overflows in some (rare) conditions and must be removed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

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

lib: Add initial rtt estimator to FRCT

2019-02-08T11:39:23+00:00

This adds a simple round-trip time estimator to FRCT. The estimate is a weighted average with deviation. The retransmission is scheduled after rtt + 2 times the deviation. A retransmit doubles the rtt estimate to avoid the no-update case when rtt suddenly increases. The rtt is estimated in microseconds and the granularity for retransmits is 256 microseconds.

tools: Allow enrollment with destination IPCP

2019-01-16T11:10:15+00:00

The irm enroll tool had a semantic to enroll with a layer name, but this is not checked. Now the enroll command will retrieve the correct layer name that the IPCP got from the actual enrollment procedure. The irm enroll now has two string parameters, a dst and a layer, which cannot be both NULL. If only dst is specified, the IPCP will enroll with that name; autobind will bind with the layer name. If only layer is specified, the IPCP will enroll with the layer name, and perform a check that the layer name retrieved from enrollment is indeed the layer name before possibly autobinding. If both dst and layer are specified, the IPCP will enroll with dst and perform a check that the enrollment was in the expected layer. Basically only specifying the layer name is a shorthand for dst == layer. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

tools: Rename "normal" to "unicast"

2019-01-02T15:45:09+00:00

This renames the normal IPCP to unicast in the irm toolkit. 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.
