[PATCH net 0/2] rxrpc: RACK-TLP fixes
From: David Howells
Date: Fri Sep 25 2026 - 15:18:27 EST
Here are some fixes for AF_RXRPC's RACK-TLP implementation. It's split
into two patches: the first just fixes the RFC number in comments but has
no actual code changes; the second does the actual fixing, including:
- Making the in/exiting fast/RTO recovery flags available to RACK-TLP code
after the Reorder timer expires.
- Arming the RTO timer if no other timer is running and there is unacked
data.
- Initialising the TLP state in the correct place.
- Not resetting the xmit timestamp when marking a packet lost.
- Correctly checking the flight size.
- Correctly tracking the number of packets in the Tx window that have been
re-sent and thus correctly estimating the flight size.
