Section 3.3.2, Fig. 5 says:

Figure 5:
rcv RST (note 1)

Note 1:
The transition from SYN-RECEIVED to LISTEN on receiving a RST is 
conditional on having reached SYN-RECEIVED after a passive OPEN.

It should say:

Figure 5:
rcv RST/SYN (note 1)

Note 1:
When a connection in SYN-RECEIVED was reached through a passive OPEN, 
the connection returns to LISTEN in two cases, as specified in Section 
3.10.7.4:
(1) when a RST is received, and (2) when a SYN is received.

Notes:

Rationale:
Section 3.10.7.4 specifies two cases in which a connection in SYN-RECEIVED, reached via a passive OPEN, returns to LISTEN: when a RST is received and when a SYN is received. Figure 5's edge label and Note 1 currently mention only the RST-based case. This change does not introduce new behavior; it aligns the label and Note 1 with the existing normative text.
