Hi Randall et all,
I agree that the "Errata" is not valid.

Subject: [tsvwg] Re: [Technical Errata Reported] RFC9260 (7988)

Hello:


So I have just had a look at this "Errata". I disagree with it. Section
3 defines data formats and

does not specify what IP addresses are accepted or used in sending an
INIT. Section 5 has details

on association setup. Note also that Section 5 explicitly states that
the receiver of an INIT must

respond to the senders IP address NOT any of the IP addresses listed
within the INIT chunk. This

is an important security concern. A secondary listed address cannot be
used until a heart beat

validates the address by sending a HB to the address and receiving a
response from the address.


The Errata IMO is invalid ... Michael? Do you agree or am I missing
something??
