lib: Rename timerwheel_ack timerwheel_delayed_ack

2022-04-13T06:54:15+00:00

This makes it clear that we are scheduling a potential delayed acknowledgment instead of acknowledging a packet scheduled for retransmission. Also some small cosmetic fixes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Expose flow control metrics to RIB

2022-03-16T12:12:50+00:00

This exposes some additional metrics relating to FRCT / Flow control: the number of duplicate packets received, number of packets received out of the flow control window and / or reordering queue, and the number of rendez-vous messages sent.

lib: Fix buffer allocation when retransmitting

2022-03-11T16:51:27+00:00

The timerwheel was retransmitting packets and the error check for negative values of the rbuff allocation was instead checking for non-zero values, causing a buffer allocation to succeed but the program to continue down the unhappy path leaving that packet stuck in the buffer unattended. Also fixes wrongly scheduled retransmissions that cause packet storms. FRCP is much more stable now. Still needs some work for high bandwidth-delay products (fast-retransmit).

build: Add debug option for fsanitize=undefined

2022-03-08T16:40:18+00:00

The sanitizer for undefined behaviour can now be enabled using DebugUSan build option for convenience. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Ease lock in timerwheel

2021-12-22T15:37:41+00:00

It was taking a write lock when a read lock was sufficient. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Install into /usr/local by default on OS X

2021-10-29T15:06:02+00:00

On more recent Mac OS X (>= Catalina) the system volume is read-only, even with System Integrity Protection disabled. This requires an additional remount step to install something into /usr. Probably better to play by their rules and default the install to /usr/local. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

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 missing return statement

2021-06-23T06:42:15+00:00

The fa_handle_packet function loop is non-void but didn't have a return statement. Only got picked up if I build from AUR, which is weird. 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

lib: Bypass assertion in shm_rdrbuff

2021-06-21T06:46:47+00:00

This assert() causes ipcpd and subsequent irmd abort() when shutting down debug builds. Should be fixed some day when other components are more robust (frct retransmissions and routing). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
