* ipcpd: Only forward new LSAs of the LSDBSander Vrijders2018-07-151-17/+36
| | | | | | | | | | | | 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 changedSander Vrijders2018-06-191-18/+50
| | | | | | | | | 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.

* ipcpd: Change connection down to flow downSander Vrijders2018-06-197-19/+82
| | | | | | | | | | The DT component was flagging a connection as down and passing the fd that was down. Of course the other components expect a connection instead of just a fd. Now the connection manager will listen to flow up and down events, and flag the connection up or down if needed.

| * ipcpd: Get mtu using ioctl before hw addressDimitri Staessens2018-06-131-6/+6
| | | | | | | | | | | | | | | | | | The SIOCGIFMTU command uses the ifr struct, which is a union, so it can't store the hw address and the MTU at the same time. We now call SIOCGIFMTU and set the MTU before SIOCGIFHWADDR. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
