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.

2018-04-10Merge #12731: Support serialization as another type without castingWladimir J. van der Laan
818dc74 Support serialization as another type without casting (Pieter Wuille) Pull request description: This adds a `READWRITEAS(type, obj)` macro which serializes `obj` as if it were converted to `const type&` when `const`, and to `type&` when non-`const`. No actual cast is involved, so this only works when this conversion can be done automatically. This makes it usable in serialization code that uses a single implementation for both serialization and deserializing, which doesn't know the constness of the object involved. This is a redo of #12712, using a slightly different interface.

2018-03-21Add native support for serializing char arrays without FLATDATAPieter Wuille
Support is added to serialize arrays of type char or unsigned char directly, without any wrappers. All invocations of the FLATDATA wrappers that are obsoleted by this are removed. This includes a patch by Russell Yanofsky to make char casting type safe. The serialization of CSubNet is changed to serialize a bool directly rather than though FLATDATA. This makes the serialization independent of the size of the bool type (and will use 1 byte everywhere).
2018-03-20Support serialization as another type without castingPieter Wuille

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

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: 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.
