2020-10-09net: advertise support for ADDRv2 via new messageVasil Dimov
Introduce a new message `sendaddrv2` to signal support for ADDRv2. Send the new message immediately after sending the `VERACK` message. Add support for receiving and parsing ADDRv2 messages. Send ADDRv2 messages (instead of ADDR) to a peer if he has advertised support for it. Co-authored-by: Carl Dong <contact@carldong.me>
2020-09-22Remove header checks out of net_processingTroy Giorshev
This moves header size and netmagic checking out of net_processing and into net. This check now runs in ReadHeader, so that net can exit early out of receiving bytes from the peer. IsValid is now slimmed down, so it no longer needs a MessageStartChars& parameter. Additionally this removes the rest of the m_valid_* members from CNetMessage.
2020-09-22Change CMessageHeader ConstructorTroy Giorshev
This commit removes the single-parameter contructor of CMessageHeader and replaces it with a default constructor. The single parameter contructor isn't used anywhere except for tests. There is no reason to initialize a CMessageHeader with a particular messagestart. This messagestart should always be replaced when deserializing an actual message header so that we can run checks on it. The default constructor initializes it to zero, just like the command and checksum. This also removes a parameter of a V1TransportDeserializer constructor, as it was only used for this purpose.

2020-07-19Add support for tx-relay via wtxidSuhas Daftuar
This adds a field to CNodeState that tracks whether to relay transactions with that peer via wtxid, instead of txid. As of this commit the field will always be false, but in a later commit we will add a way to negotiate turning this on via p2p messages exchanged with the peer.

2020-05-29util: dedup code in callers of serviceFlagToStr()Vasil Dimov
Introduce `serviceFlagsToStr()` which hides the internals of the bitmask and simplifies callers of `serviceFlagToStr()`.
2020-05-29util: simplify the interface of serviceFlagToStr()Vasil Dimov
Don't take two redundant arguments in `serviceFlagToStr()`. As a side effect this fixes an issue introduced in https://github.com/bitcoin/bitcoin/pull/18165 due to which the GUI could print something like `UNKNOWN[1033] & UNKNOWN[1033] & UNKNOWN[2^10]` instead of `NETWORK & WITNESS`.

2020-02-06net: Fail instead of truncate command name in CMessageHeaderWladimir J. van der Laan
Replace the memset/strncpy dance in `CMessageHeader::CMessageHeader` with explicit code that copies then name and asserts the length. This removes a warning in g++ 9.1.1 and IMO makes the code more readable by not relying on strncpy padding and silent truncation behavior.

2016-11-09Avoid ugly exception in log on unknown inv typeWladimir J. van der Laan
It is unexpected behavior for `ToString` to raise an exception. It is expected to do a best-effort attempt at formatting but never fail. Catch the exception and simply print unknown inv types as hexadecimal. Fixes #9110.
2016-09-28net: Consistent checksum handlingWladimir J. van der Laan
In principle, the checksums of P2P packets are simply 4-byte blobs which are the first four bytes of SHA256(SHA256(payload)). Currently they are handled as little-endian 32-bit integers half of the time, as blobs the other half, sometimes copying the one to the other, resulting in somewhat confused code. This PR changes the handling to be consistent both at packet creation and receiving, making it (I think) easier to understand.
