ipcpd: Send link state message before lsdb update

2018-10-12T15:35:11+00:00

When a new link is added, the link state update will be sent before the database update, so the network is a little bit more quickly aware. This improves odds of the DHT successfully enrolling at its first attempt, reducing bootstrap time of a network. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Call send_lsm under read lock

2018-10-11T18:21:44+00:00

send_lsm was being called from the event handler as well as from lsupdate. The first one was not being locked properly. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Speed up enrolment of DHT

2018-10-11T11:42:38+00:00

The link-state algorithm will now quickly recalculate for link additions (but not for removals, for stability). Upon notification of a new link, the DHT will wait for a brief moment to enroll. This reduces enrolment for large networks by some orders of magnitude. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix test of routing table calculation

2018-09-27T12:22:25+00:00

A previous commit changes the signature of the function that calculates the routing table. The test was not changed accordingly, making make check fail. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

include: Remove _DEFAULT_SOURCE in endian.h

2018-09-27T07:26:26+00:00

This removes the _DEFAULT_SOURCE definition in the endian header as it should not be there. This avoids double and conflicting definitions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Simplify routing algorithm selection

2018-09-14T08:15:55+00:00

Previously there was a separate function per routing algorithm selection, when in fact the algorithms all take as input a graph and output a routing table, making it possible to place them in a single function. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Check if mgmt flow event is FLOW_PKT

2018-07-26T22:22:24+00:00

The management flows were considering every event to be a FLOW_PKT event, when in fact it could also be a flow down or up event, resulting in indefinite reads. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Fix sequence number check for link state

2018-07-25T11:29:15+00:00

Commit a3903da659e introduced sequence number for the LSAs to make it more robust, but the check was not done properly, and the seqno was always changed regardless of whether it was an old LSA or not. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Only forward new LSAs of the LSDB

2018-07-15T09:25:58+00:00

This will add a sequence number to the Link State Advertisements so that upon receiving a LSA we can check if we need to forward the LSA or not. If we already have the LSA with the received seqno in the LSDB we do not forward it. This allows for setting up a management network that has loops since the spanning tree upon which the LSAs are sent is pruned on every hop.

ipcpd: Recalculate PFF only if LSDB changed

2018-06-19T11:57:10+00:00

This will add a flag so the PFF is only recalculated if the LSDB has changed. It also removes the instant recalculation of the LSDB if a new neighbor is added, since this might cause instabilities. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens
