Per CFDP 4.7.2 every EOF PDU must be acknowledged, and a retransmission means our previous ACK was lost. It used to be handled like a brand new EOF regardless of transaction state, which re-ran completion, re-sent a fresh Finished PDU, and restarted its positive ACK procedure on every retransmission the sender made.	2026-09-14 11:32:14 +02:00

Fix for destination handler EOF handling

Destination handler now answers a retransmitted EOF PDU instead of silently reprocessing it.
Per CFDP 4.7.2 every EOF PDU must be acknowledged, and a retransmission means our previous ACK
was lost. It used to be handled like a brand new EOF regardless of transaction state, which
re-ran completion, re-sent a fresh Finished PDU, and restarted its positive ACK procedure on
every retransmission the sender made.
