ipcpd: Fix free in fail path of readdir

2022-02-17T07:28:49+00:00

The free of the buffer in the failure path of the readdir RIB functions was taking the wrong pointer in a couple of places. The FRCT RIB readdir was missing error handling for malloc and strdup. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Pass full path for RIB entries

2021-06-29T06:56:03+00:00

The read functions for the RIB will now receive the full path, instead of only the entry name. For IPCPs, we organized the RIB in an ///entries structure with a directory per component, so we don't need the full path at this point. For process flow information, it's a lot more convenient to organize it the following way ///stat We can then register/unregister the flow descriptor when the frct instance is created, and for getting the stats, we'd know the flow descriptor from the fuse file path. If we would create a file per flow instead of a directory per flow, something like //flows/ we'd need to do additional bookkeeping to list the contents of that directory (we would need to track all flows with an active FRCT instance), that fuse knows because it tracks the directories.

ipcpd: Fix unregistering fa and dt RIBs

2021-06-28T13:29:23+00:00

These RIBs were not properly unregistered on shutdown. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Remove struct stat from RIB API

2021-06-28T13:29:19+00:00

The RIB API had a struct stat in the getattr() function, which made all components that exposed variables via the RIB dependent on . The rib now has its own struct rib_attr to set attributes such as size and last modified time. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Fix compilation with fuse (RIB) on FreeBSD

2021-06-28T13:29:16+00:00

Compilation failed on FreeBSD 14 with fuse enabled because of some missing definitions. __XSI_VISIBLE must be set before including for some definitions in . FreeBSD doesn't know the MSG_CONFIRM flag to sendto() or CLOCK_REALTIME_COARSE, which are Linux-specific. 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: Pass qoscube to ECN marking function

2020-12-20T12:36:44+00:00

The ECN marking function should be able to use the packet QoS to allow prioritizing traffic under congestion. Not yet implemented in MB-ECN. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Pass previous ECN value in congestion API

2020-12-12T10:38:00+00:00

The previous value of the ECN field should be passed to the congestion notification function. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
