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

ipcpd: Fix congestion window scaling

2021-06-21T06:45:42+00:00

This fixes scaling of the congestion window, which was a buggy mess. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix free of uninitialized variable in graph.c

2021-05-28T06:19:53+00:00

The new GCC 11.1 compiler discovered s_dist would be uninitialized with an unknown policy, so it doesn't need to be free'd. Also removes some unneeded includes in broadcast dt.c that I had pending. 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

The ugent email addresses are shut down, updated to Ouroboros mail addresses. 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: Remove unused variable in MB-ECN policy

2020-12-12T10:38:05+00:00

The t_sent variable is a remnant from the first version and isn't needed anymore. 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

ipcpd: Fix slow start in multi-bit (F)ECN policy

2020-12-07T17:39:45+00:00

There is a check not to rapidly double the window to astronomical sizes when there is no congestion experienced for long periods of time, but the if-else logic was botched and it still grew to astronomical sizes (albeit linear instead of exponential). I also lowered the ECN threshold a bit. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
