ipcpd, lib, irmd, tools: Change SDU to packet

2018-10-05T08:35:25+00:00

This will change SDU (Service Data Unit) to packet everywhere. SDU is OSI terminology, whereas packet is Ouroboros terminology. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

include: Remove _DEFAULT_SOURCE in endian.h

2018-09-27T07:26:26+00:00

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 Signed-off-by: Sander Vrijders

ipcpd: React to flow events actively

2018-07-04T14:16:41+00:00

This adds the infrastructure to actively react to flow up, down and deallocated events. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

lib: Add a data qos cube

2018-06-08T08:26:07+00:00

This adds a data qos cube that is reliable. Reliable qos can be selected by setting the loss parameter of the qosspec to 0. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add priority for raw flows

2018-06-07T15:52:10+00:00

The raw flows had no priority assigned, causing the scheduler to fail on creation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Enable locking threads to a CPU core

2018-04-05T08:31:52+00:00

This adds a function that locks a thread to a random core. This greatly improves performance on multi-cpu systems. There is no portable way to do this, this only implements it for GNU/Linux. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix cleanup of sdu scheduler

2018-02-24T08:16:09+00:00

Not all threads were cancelled on exit. This fixes (the rather cryptic) error message "The futex facility returned an unexpected error code" when running the stack with the address sanitizer. Also fixes possible double frees when a pthread_create would fail. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

Happy New Year, Ouroboros. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add multiplier to scale scheduler threads

2017-09-25T15:10:11+00:00

ipcpd: Use the kernel scheduler for QoS

2017-09-21T12:47:29+00:00

This revises the sdu_scheduler of the normal IPCP to create a scheduler thread per QoS cube and let the kernel scheduler schedule them based on a priority. Priorities can be set at build time in a range of 0-100, which will be mapped onto a suitable priority for the kernel scheduler. The current scheduler policy is fixed to SCHED_RR since it is the most suitable scheduler defined by POSIX.
