| * include: Remove _DEFAULT_SOURCE in endian.hDimitri Staessens2018-09-2725-3/+101
| | | | | | | | | | | | | | | | 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 <[email protected]> Signed-off-by: Sander Vrijders <[email protected]>
| * 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.

* | lib: Support for rudimentary retransmissionDimitri Staessens2018-07-278-403/+326
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | This adds rudimentary support for sending and processing acknowledgments and doing retransmission. It replaces the generic timerwheel with a specific one for retransmission. This is currently a fixed wheel allowing retransmissions to be scheduled up to about 32 seconds into the future. It currently has an 8ms resolution. This could be made configurable in the future. Failures of the flow (i.e. rtx not working) are indicated by the rxmwheel_move() function returning a fd. This is currently not yet handled (maybe just setting the state of the flow to FLOWDOWN is a better solution). The shm_rdrbuff tracks the number of users of a du_buff. One user is the full stack, each retransmission will increment the refs counter (which effectively acts as a semaphore). The refs counter is decremented when a packet is acked. The du_buff is only allowed to be removed if there is only one user left (the "stack"). When a packet is retransmitted, it is copied in the rdrbuff. This is to ensure integrity of the packet when multiple layers do retransmission and it is passed down the stack again.

* 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 <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* 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.

* tools: Enhance irm connect and disconnect command0.11.10Sander Vrijders2018-07-232-26/+34
| | | | | | | | | | This enhances the irm connect and irm disconnect command to allow creating connections between IPCPs based on wildcard matching for the component name. In case no component was specified it sets up connections between all possible components. Signed-off-by: Sander Vrijders <[email protected]> Signed-off-by: Dimitri Staessens <[email protected]>
* 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.
