* tools: Specify QoS cube for data transfer flows0.13.0Dimitri Staessens2018-10-194-6/+10
| | | | | | | | | The ipcp connect command can now set a specific qos cube for data transfer flows. For management flows, the tool ignores this and defaults to raw until data flows are stable enough.

* ipcpd: Check if there are entries to add to pffDimitri Staessens2018-10-191-3/+3
| | | | | | | | The pff didn't check if there were actually entries in the database, causing an assertion failure in some rare cases. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd, irmd: Handle signal in main threadDimitri Staessens2018-10-183-64/+52
| | | | | | | | | The signals are now handled in the main thread instead of an asynchronous signal handler. The acceptloop is now correctly cancelled and the associated timeouts are removed.

* ipcpd: Send link state message before lsdb update0.12.3Dimitri Staessens2018-10-121-5/+4
| | | | | | | | | | 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.

* ipcpd: Make Qdisc bypass configurableSander Vrijders2018-10-123-0/+7
| | | | | | | | This will make bypassing the qdisc configurable, as it might be handy for getting fast data rates but is generally needed. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Call send_lsm under read lockSander Vrijders2018-10-111-0/+2
| | | | | | | | 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 <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Take correct lock when updating statsSander Vrijders2018-10-111-2/+4
| | | | | | | | The lock of the wrong fd was taken when updating the stats in the DT component. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Speed up enrolment of DHTDimitri Staessens2018-10-112-62/+68
| | | | | | | | | | | 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.

* ipcpd: Decouple flow allocator from dt threadDimitri Staessens2018-10-111-86/+176
| | | | | | | | The flow allocator passed a blocking callback to the forwarding component, which blocks packet processing. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Remove stale QoS cubesDimitri Staessens2018-10-103-17/+1

* ipcpd: Fix SEGV in eth IPCPDimitri Staessens2018-10-101-1/+6

* ipcpd, lib, irmd, tools: Change SDU to packetSander Vrijders2018-10-0510-196/+198
| | | | | | | | This will change SDU (Service Data Unit) to packet everywhere. SDU is OSI terminology, whereas packet is Ouroboros terminology. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Replace SAP with EID in raptor IPCPSander Vrijders2018-10-051-74/+74
| | | | | | | | This replaces Service Access Point with Endpoint Identifier in the raptor IPCP, since it better fits the Ouroboros terminology. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* lib: Pass qosspec at flow allocationDimitri Staessens2018-10-0510-83/+174
| | | | | | | | | | | | The flow allocator now passes the full qos specification to the endpoint, instead of just a cube. This is a more flexible architecture, as it makes QoS cubes internal to the layers. Adds endianness transforms for the flow allocator protocol in the normal IPCP.

* ipcpd: Use non-blocking socket in Ethernet IPCPSander Vrijders2018-10-031-3/+17
| | | | | | | | | | Since the Ethernet IPCP now has multiple reader threads it was possible that both exit the select call, which caused one of the two threads to block on the recv call. This makes the socket non-blocking so that the recv call simply fails. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* build: Prioritize raw socket API in buildSander Vrijders2018-10-031-15/+18
| | | | | | | | This will change the build to exclusively select one raw socket API in case multiple are present in the sytem, which will simplify the code. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Bypass Qdisc in Ethernet IPCPSander Vrijders2018-10-031-0/+8

* ipcpd: Fix build for netmap enabled Ethernet IPCPSander Vrijders2018-10-032-7/+9
| | | | | | | | | There were some compilation issues introduced by adding the interface monitor to the Ethernet IPCP. Furthermore it was not possible to select between raw sockets or netmap if both were available.

* ipcpd: Add multithreading to Ethernet IPCPDimitri Staessens2018-10-033-31/+63
| | | | | | | | | This adds multiple reader and writer threads, configurabe via cmake with IPCP_ETH_RD_THR and IPCP_ETH_WR_THR. Improves ethernet IPCP throughput, which looks to be limited by the raw socket calls.

* ipcpd: Fix test of routing table calculationSander Vrijders2018-09-271-4/+4
| | | | | | | | | 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 <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Remove double close in Ethernet IPCPSander Vrijders2018-09-271-2/+1
| | | | | | | | | There was a double close of a fd in the Ethernet IPCP. It also passes the correct max length to a memcpy (a strlen of the source string was used previously). Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* include: Remove _DEFAULT_SOURCE in endian.hDimitri Staessens2018-09-2716-0/+62
| | | | | | | | 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 <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* ipcpd: Simplify routing algorithm selectionSander Vrijders2018-09-143-89/+85
| | | | | | | | | | 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.

* ipcpd: Check if mgmt flow event is FLOW_PKT0.11.12Sander Vrijders2018-07-271-1/+4
| | | | | | | | | 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 <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>
* ipcpd: Fix sequence number check for link state0.11.11Sander Vrijders2018-07-251-11/+11
| | | | | | | | | 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.

* 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 Vrijders2018-06-196-6/+67
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.
