ipcpd: Make the DHT a directory policy

2021-12-06T16:52:56+00:00

The DHT is now a proper directory policy instead of a unicast IPCP component. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Move DHT to stack

2021-12-06T16:52:16+00:00

This makes the DHT a single directory implementation and moves it to the stack (init/fini instead of create/destroy). This is a step towards making it a directory policy, in line with our other policy implementations. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib, ipcpd, irmd: Wrap pthread unlocks for cleanup

2021-06-23T06:36:48+00:00

This add an ouroboros/pthread.h header that wraps the pthread_..._unlock() functions for cleanup using pthread_cleanup_push() as this casting is not safe (and there were definitely bad casts in the code). The close() function is now also wrapped for cleanup in ouroboros/sockets.h. This allows enabling more compiler checks. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Move connmgr and enrolment to common ground

2021-03-28T10:46:32+00:00

The connection manager and enrolment components of the unicast and broadcast IPCP have a lot in common, as conjectured in the paper. The initial implementation of the broadcast IPCP just duplicated the code. This moves the shared functionality to common ground. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Use 64-bit flow endpoint IDs for DT

2020-12-07T17:39:48+00:00

The EIDs are now 64-bit. This makes it a tad harder to guess them (think of port scanning). The implementation has only the most significant 32 bits random to quickly map EIDs to N+1 flows. While this is equivalent to a random cookie as a check on flows, the rationale is that valid endpoint IDs should be pretty hard to guess (and thus be 64-bit random at least). Ideally one would use content-addressable memory for this kind of mapping. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Remove DT-FA bypass on receiver side

2020-12-07T17:39:41+00:00

The DT will now post all packets for N+1 flows through the flow allocator component. This means that N+1 flows can be monitored through the flow allocator stats, and N-1 flows through the DT stats. The DT component still keeps stats for the local components (FA and DHT), but this can be removed once the DHT has its own RIB output. The flow allocator show statistics for Sent packets: total packets that were presented for sending on this specific flow Send failed: packets that were unable to be sent Received packets: total packets that were presented by the DT component on this specific flow Received failed: packets that were unable to be delivered These stats are presented as both packet counts and byte counts. To know how many were successful, the values for failed need to be subtracted from the values for total. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix assert in dht

2020-09-26T14:04:24+00:00

Fix assignment instead of comparison operator. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix leak and unitialized variable in DHT

2020-05-29T15:06:39+00:00

There were some issues identified by the Clang static analyzer that are now fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
