ouroboros, branch 0.18.3

build: Bump patch level version number

2021-09-11T10:41:20+00:00

The last couple of commits fix compilation on OS X. So bumping the patchlevel makes sense to fix compilation for the master branch as well. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Fix conversion to uint64_t

2021-09-05T15:03:48+00:00

The print output for MB-ECN had a size_t conversion to uint64_t that some compilers complain about. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Don't include prctl.h on non-linux systems

2021-09-05T15:03:45+00:00

prctl.h is linux only. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Don't use sigwaitinfo() on OS X

2021-09-05T15:03:42+00:00

Apparently that function isn't implemented on some versions of OS X. On these systems, we can just use sigwait, but now the IPCP will also accept signals not coming from the IRMd. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix additive increase in CA-MB-ECN

2021-07-21T09:46:24+00:00

The logic for additive increase was botched. It was adding to the current window limit, and to avoid a count-to-infinity when sending below the limit, I added a check that the application was trying to send more than the current limit. This fails in congestion avoidance mode when the IPCP is throttling traffic below the limit; causing the app to never increase the congestion window (and even worse, to keep decreasing in some cases). The Additive Increase will now always add bandwidth to the latest sending rate instead of the window bandwidth limit, avoiding all the problems.

ipcpd: Fix flow allocator build without fuse

2021-07-18T12:13:56+00:00

The u_snd and u_rcv variables were not guarded by ifdefs when updating. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Export flow updates sent/recvd to fa RIB

2021-07-12T07:09:47+00:00

The RIB of the flow allocator will now export the number of flow updates sent/received per flow. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Reduce Linux slack timer

2021-07-12T07:09:44+00:00

This will reduce the linux high resolution slack timer in IPCPs. Linux default for userspace processes is 50us. It is configurable at build using IPCP_LINUX_SLACKTIMER_NS. Default is now 1us. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix update rate for Multi-Bit ECN

2021-07-12T07:07:54+00:00

The rate was supposed to be 1 update per 8 data packets, but the calculation was doing 1 update per 4 data packets. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

unicast: Fix RIB stats for congestion avoidance

2021-07-10T14:35:04+00:00

The upstream/downstream stats were switched. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
