2018-01-24Merge #11512: Use GetDesireableServiceFlags in seeds, dnsseeds, fixing ↵Wladimir J. van der Laan
static seed adding 2b839ab Update chainparams comment for more info on service bits per dnsseed (Matt Corallo) 62e7642 Fall back to oneshot for DNS Seeds which don't support filtering. (Matt Corallo) 51ae766 Use GetDesireableServiceFlags in static seeds, document this. (Matt Corallo) fb6f6b1 bluematt's testnet-seed now supports x9 (and is just a static list) (Matt Corallo) Pull request description: 4440710 broke inserting entries into addrman from dnsseeds which did not support service bits, as well as static seeds. Static seeds were already being filtered by UA for 0.13.1+ (ie NODE_WITNESS), so simply changing the default service bits to include NODE_WITNESS (and updating docs appropriately) is sufficient. For DNS Seeds, not supporting NODE_WITNESS is no longer useful, so instead use non-filtering seeds as oneshot hosts irrespective of named proxy. I've set my testnet-seed to also support x9, though because it is simply a static host, it may be useful to leave the support off so that it is used as a oneshot to get addresses from a live node instead. I'm fine with either. Tree-SHA512: 3f17d4d2b0b84d876981c962d2b44cb0c8f95f52c56a48c6b35fd882f6d7a40805f320ec452985a1c0b34aebddb1922709156c3ceccd1b9f8363fd7cb537d21d

44407100f broke inserting entries into addrman from static seeds (as well as dnsseeds which did not support service bits). Static seeds were already being filtered by UA for 0.13.1+ (ie NODE_WITNESS), so simply changing the default service bits to include NODE_WITNESS (and updating docs appropriately) is sufficient. For DNS Seeds, we will later fix by falling back to oneshot if a seed does not support filtering.

2017-10-13Replace relevant services logic with a function suite.Matt Corallo
Adds HasAllRelevantServices and GetRelevantServices, which check for NETWORK|WITNESS. This changes the following: * Removes nRelevantServices from CConnman, disconnecting it a bit more from protocol-level logic. * Replaces our sometimes-connect-to-!WITNESS-nodes logic with simply always requiring WITNESS|NETWORK for outbound non-feeler connections (feelers still only require NETWORK). * This has the added benefit of removing nServicesExpected from CNode - instead letting net_processing's VERSION message handling simply check HasAllRelevantServices. * This implies we believe WITNESS nodes to continue to be a significant majority of nodes on the network, but also because we cannot sync properly from !WITNESS nodes, it is strange to continue using our valuable outbound slots on them. * In order to prevent this change from preventing connection to -connect= nodes which have !WITNESS, -connect nodes are now given the "addnode" flag. This also allows outbound connections to !NODE_NETWORK nodes for -connect nodes (which was already true of addnodes). * Has the (somewhat unintended) consequence of changing one of the eviction metrics from the same sometimes-connect-to-!WITNESS-nodes metric to requiring HasRelevantServices. This should make NODE_NETWORK_LIMITED much simpler to implement.

2016-11-07Get rid of nType and nVersionPieter Wuille
Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
2016-10-05protocol.h: Make enums in GetDataMsg concrete valuesWladimir J. van der Laan
This concretizes the numbers and adds a comment to make it clear that these numbers are fixed by the protocol, and may avoid people forgetting to claim numbers in the future (e.g. issue #8500). Also gets rid of a weird unused `MSG_TYPE_MAX` in the middle of the enumeration (thanks @paveljanik for noticing).

2016-09-28net: Hardcode protocol sizes and use fixed-size typesWladimir J. van der Laan
The P2P network uses a fixed protocol, these sizes shouldn't change based on what happens to be the architecture.
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.

2016-03-21Implement "feefilter" P2P message.Alex Morcos
The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.

2015-12-10net: Add and document network messages in protocol.hWladimir J. van der Laan
- Avoids string typos (by making the compiler check) - Makes it easier to grep for handling/generation of a certain message type - Refer directly to documentation by following the symbol in IDE - Move list of valid message types to protocol.cpp: protocol.cpp is a more appropriate place for this, and having the array there makes it easier to keep things consistent.
2015-09-05Add NODE_BLOOM service bit and bump protocol versionMatt Corallo
Lets nodes advertise that they offer bloom filter support explicitly. The protocol version bump allows SPV nodes to assume that NODE_BLOOM is set if NODE_NETWORK is set for pre-70011 nodes. Also adds an option to turn bloom filter support off for nodes which advertise a version number >= 70011. Nodes attempting to use bloom filters on such protocol versions are banned, and a later upgade should drop nodes of an older version which attempt to use bloom filters. Much code stolen from Peter Todd. Implements BIP 111

Thanks to Pieter Wuille for most of the work on this commit. I did not fixup the overhaul commit, because a rebase conflicted with "remove fields of ser_streamplaceholder". I prefer not to risk making a mistake while resolving it.
2014-08-31overhaul serialization codeKamil Domanski
The implementation of each class' serialization/deserialization is no longer passed within a macro. The implementation now lies within a template of form: template <typename T, typename Stream, typename Operation> inline static size_t SerializationOp(T thisPtr, Stream& s, Operation ser_action, int nType, int nVersion) { size_t nSerSize = 0; /* CODE */ return nSerSize; } In cases when codepath should depend on whether or not we are just deserializing (old fGetSize, fWrite, fRead flags) an additional clause can be used: bool fRead = boost::is_same<Operation, CSerActionUnserialize>(); The IMPLEMENT_SERIALIZE macro will now be a freestanding clause added within class' body (similiar to Qt's Q_OBJECT) to implement GetSerializeSize, Serialize and Unserialize. These are now wrappers around the "SerializationOp" template.
