build: Add version and symlinks to shared objects

Building with Yocto was giving some package QA warnings. Signed-off-by: Dimitri Staessens

irmd: Refactor main function

2022-07-13T06:56:02+00:00

This splits the main function into init/start/sigwait/stop/fini to make it easier to read, similar to the IPCPs. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Refactor main functions

2022-07-13T06:56:02+00:00

The structure of main functions of the IPCPs was a bit strange with a ipcp_shutdown() call that combined waiting for a terminating signal with stopping the internal threads. This is now revised into a symmetrical design of ipcp_start(), which now includes the create response towards the IRMd. ipcp_sigwait(), which waits for a shutdown signal ipcp_stop() that then stops the internal threads. Now the main() functions of the IPCPs will make sense without checking what that ipcp_shutdown() functions actually does. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix dealloc with unread keepalives

2022-05-25T06:10:22+00:00

The dealloc call will now always do a non-blocking read before attempting to destroy the rbuff, ensuring all keepalives are processed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix deadlock on exit in udp, local, eth

2022-05-22T13:11:22+00:00

The IPCP flow_set was getting destroyed with the IPCP main loop still running, causing potential deadlocks. Reported-by: Thijs Paelman Confirmed-by: Dimitri Staessens Tested-by: Dimitri Staessens Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

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: Fix RTO update on timeout

2022-04-03T16:01:02+00:00

This fixes the RTO doubling on timeout according to Karn/Partridge. Exponentially increasing RTO when it times out (e.g. doubling) fixes the problem that a sudden increase in real RTT starves the sRTT updates by never getting out of backoff as retransmitted packets can't update RTT. Added an parameter to make it less aggressive, default is doubling. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Remove timerwheel from instance

2022-04-03T16:01:02+00:00

There was an unused struct timerwheel * lingering in the application instance. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix delayed ACK under high load

2022-04-03T16:01:01+00:00

The delayed ACK was wrongly measuring the delay against the receiver activity instead of the sender activity. Also fixed receiver activity not being updated for non-data packets (and duplicates and other dropped traffic). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
