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

lib: Fix waiting for FRCT at deallocation

2021-12-22T15:35:55+00:00

This is a fix to wait for outstanding retransmissions when a flow is deallocated. Instead of waiting the full timeout, it will now wait in the same tic increments used within FRCT. Bit of a stopgap at the moment, FRCT and the flows are in need of a serious refactor. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add missing rwlock unlock in FRCT

2021-12-22T15:35:18+00:00

There was a missing unlock in FRCT. Also fixes some indentation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix waiting for FRCP to time out

2021-12-22T15:34:56+00:00

The timeout variable was not correctly passed to the IPCP, causing flow IDs to be reused immediately instead of waiting for the full Delta-t to expire. This caused all kinds of havoc with retransmissions in reliable flows. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix flow dealloc after expired FRCT timeout

2021-12-22T15:34:27+00:00

If the timeout is already expired, the wait variable would be negative and return a negative value for the __frcti_dealloc function, thinking that the timeout was not expired causing an unnecessary wait even if all packets are acknowledged.

lib: Set initial sender rwe to sender seqno

2021-12-22T15:33:50+00:00

The initial sender right window edge (indicating acknowledged packet sequence number) was initialized to seqno - 1. This should be the same as seqno, since we acknowledge with the next expected sequence number. It also indicates that a flow without traffic has no outstanding acknowledgements.

ipcpd: Add dt component to regular startup flow

2021-12-06T16:54:35+00:00

The dt component had init/start commands somewhat outside of the overall flow of startup of the unicast IPCP. This was probably some old code and wasn't needed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Consolidate policies within folder

2021-12-06T16:53:52+00:00

Each policy folder will now have a pol.h file, so that (in most cases) adding a new policy only requires changes inside the policy folder. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Make the DHT a directory policy

2021-12-06T16:52:56+00:00

The DHT is now a proper directory policy instead of a unicast IPCP component. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Move DHT to stack

2021-12-06T16:52:16+00:00

This makes the DHT a single directory implementation and moves it to the stack (init/fini instead of create/destroy). This is a step towards making it a directory policy, in line with our other policy implementations. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
