Status: Verified
Type: Technical
Reported by: Iñaki Baz Castillo <ibc@aliax.net>
Date Reported: May 2, 2025, 7 p.m.
Verified by: Gorry Fairhurst (IESG)

Section 5.1.6 says:

Original Text
-------------
If the T1-init timer expires at "A" after the INIT or COOKIE ECHO
chunks are sent, the same INIT or COOKIE ECHO chunk with the same
Initiate Tag (i.e., Tag_A) or State Cookie is retransmitted and the
timer is restarted.

Corrected Text
--------------
If the T1-init timer expires at "A" after the INIT chunk is sent, the
same INIT chunk with the same Initiate Tag (i.e., Tag_A) is retransmitted
and the T1-init timer is restarted.

If the T1-cookie timer expires at "A" after the the COOKIE ECHO chunk
is sent, the same COOKIE ECHO chunk with the same State Cookie is
retransmitted and the T1-cookie timer is restarted.

Notes
-----
The original text said the T1-init timer is cancelled at "A" upon receipt of INIT ACK chunk from "Z", so it is impossible that the T1-init timer expires at "A" after the COOKIE ECHO chunk is sent (since COOKIE ECHO chunk is immediately sent after INIT ACK chunk is received). The text is updated to clarify two cases. Text suggestion expanded by M. Tuexen.
