Move special CAddress-without-nTime logic to net_processing #20541

  1. sipa commented at 7:04 pm on December 1, 2020: member

    Historically, the VERSION message contains an “addrMe” and an “addrYou”. As these are sent before version negotiation is complete, the protocol version is INIT_PROTO_VERSION (209), and in that protocol, CAddress is serialized without nTime.

    This is in fact the only situation left where a CAddress is (de)serialized without nTime. As it’s such a simple structure (CService for ip/port + uint64_t for nServices), just inline that structure in the few places where it occurs, and remove the logic for dealing with missing nTime from CAddress.

    sipa commented at 9:43 am on December 2, 2020:

    31402 is the protocol version that introduced the nTime field in CAddress. INIT_PROTO_VERSION (=209) being below it is the reason why the addresses inside the version message don’t have it. There is no code left that depends on this, as all connections must be MIN_PEER_PROTO_VERSION (31800) after version negotiation now.

    • 209 is from may 2010
    • 31402 is from october 2010
    • 31800 is from december 2010

    ACK 158c0ec1

    It is somewhat worrying that all tests passed with the swapped services and address, but when I think about it - it is 8 bytes service flags + 16 bytes address + 2 bytes port. I guess we can’t do any sanity check on those as any 26 random bytes could be valid.

  16. MarcoFalke commented at 7:28 am on December 3, 2020: member

    It is somewhat worrying that all tests passed with the swapped services and address

    Indeed. I think we should add unit test vectors for all message types with an example message and the expected deserialization? Assert that both are identical. Though, message format (deserialization) is handled in the same function that does the processing, so I am not sure how to test this in general without rewriting net_processing.

  17. sipa commented at 7:08 pm on December 3, 2020: member

    It is somewhat worrying that all tests passed with the swapped services and address

    It is, but that’s at least partially explained by the fact that we barely use these values. One is ignored entirely, the other is used for statistics about our local IP. The nService fields are also ignored entirely.

    I think we should add unit test vectors for all message types with an example message and the expected deserialization?

    That makes sense.

    I’m not sure that references to version 31402 are very useful (beyond being a historical footnote). The version message contains {services, ipv6 addr, port} elements - the fact that that also used to be how address records used to be serialized in addr messages is not helpful in understanding the current protocol.
    sipa commented at 7:18 pm on August 20, 2021:
    I think they’re useful for the time being, as I’d expect more descriptions and documentations of the protocol will keep referring to these fields as CAddresses.

    When we receive a version message, we ignore the following fields:

    • (4) receiver’s services
    • (7) sender’s services (duplicate with field 2 - services)
    • (8/9) sender’s ipv6 addr/port

    Perhaps in the next p2p version bump, we should explicitly document those fields as unused, since there’s no purpose for them.

  41. refactor: move CAddress-without-nTime logic to net_processing 
    Historically, the VERSION message contains an "addrMe" and an "addrYou". As
these are sent before version negotiation is complete, the protocol version is
INIT_PROTO_VERSION (209), and in that protocol, CAddress is serialized without
nTime.

This is in fact the only situation left where a CAddress is (de)serialized
without nTime. As it's such a simple structure (CService for ip/port + uint64_t
for nServices), just inline that structure in the few places where it occurs,
and remove the logic for dealing with missing nTime from CAddress.

  42. Drop us=... message in net debug for sending version message 
    The us=... message in the debug log when sending a version message is
always [::]:0, because we no longer send our own address there.
Therefore, this information is entirely redundant. Remove it.
