2022-05-21refactor: Remove defunct attributes.h includesBen Woosley
Since the removal of NODISCARD in 81d5af42f4dba5b68a597536cad7f61894dc22a3, the only attributes def is LIFETIMEBOUND, and it's included in many more places that it is used. This removes all includes which do not have an associated use of LIFETIMEBOUND, and adds it to the following files, due to their use of the same: * src/validationinterface.h * src/script/standard.h

2022-02-11net: add CServiceHash constructor so the caller can provide the saltsVasil Dimov
This new constructor will be useful if we just want to hash a `CService` object without the two `GetRand()` calls (in `RelayAddress()` in a subsequent commit).

2021-11-03net: relay CJDNS addresses even if we are not connected to CJDNSVasil Dimov
This will help with propagation, so that multi-homed nodes can learn CJDNS addresses outside of the CJDNS network.
2021-11-03net: recognize CJDNS addresses as suchVasil Dimov
In some cases addresses come from an external source as a string or as a `struct sockaddr_in6`, without a tag to tell whether it is a private IPv6 or a CJDNS address. In those cases interpret the address as a CJDNS address instead of an IPv6 address if `-cjdnsreachable` is set and the seemingly-IPv6-address belongs to `fc00::/8`. Those external sources are: * `-externalip=` * `-bind=` * UPnP * `getifaddrs(3)` (called through `-discover`) * `addnode` * `connect` * incoming connections (returned by `accept(2)`)

2021-07-09net: change assumed I2P port to 0Vasil Dimov
* When accepting an I2P connection, assume the peer has port 0 instead of the default 8333 (for mainnet). It is not being sent to us, so we must assume something. * When deriving our own I2P listen CService use port 0 instead of the default 8333 (for mainnet). So that we later advertise it to peers with port 0. In the I2P protocol SAM 3.1 and older (we use 3.1) ports are not used, so they are irrelevant. However in SAM 3.2 and newer ports are used and from the point of view of SAM 3.2, a peer using SAM 3.1 seems to have specified port=0.

Unfortunately, CSubNet objects are serialized on disk in banlist.dat, breaking compatibility with existing banlists (and bringing them into an inconsistent state where entries reported in `listbanned` cannot be removed). Fix this by reverting to the old format (just for serialization). Also add a sanity check to the deserializer so that nonsensical banlist.dat entries are ignored (which would otherwise be possible if someone added IPv4 entries after #19628 but without this PR).

2020-08-24net: change CNetAddr::ip to have flexible sizeVasil Dimov
Before this change `CNetAddr::ip` was a fixed-size array of 16 bytes, not being able to store larger addresses (e.g. TORv3) and encoded smaller ones as 16-byte IPv6 addresses. Change its type to `prevector`, so that it can hold larger addresses and do not disguise non-IPv6 addresses as IPv6. So the IPv4 address `1.2.3.4` is now encoded as `01020304` instead of `00000000000000000000FFFF01020304`. Rename `CNetAddr::ip` to `CNetAddr::m_addr` because it is not an "IP" or "IP address" (TOR addresses are not IP addresses). In order to preserve backward compatibility with serialization (where e.g. `1.2.3.4` is serialized as `00000000000000000000FFFF01020304`) introduce `CNetAddr` dedicated legacy serialize/unserialize methods. Adjust `CSubNet` accordingly. Still use `CSubNet::netmask[]` of fixed 16 bytes, but use the first 4 for IPv4 (not the last 4). Only allow subnetting for IPv4 and IPv6. Co-authored-by: Carl Dong <contact@carldong.me>
2020-07-27net: save the network type explicitly in CNetAddrVasil Dimov
Before this change, we would analyze the contents of `CNetAddr::ip[16]` in order to tell which type is an address. Change this by introducing a new member `CNetAddr::m_net` that explicitly tells the type of the address. This is necessary because in BIP155 we will not be able to tell the address type by just looking at its raw representation (e.g. both TORv3 and I2P are "seemingly random" 32 bytes). As a side effect of this change we no longer need to store IPv4 addresses encoded as IPv6 addresses - we can store them in proper 4 bytes (will be done in a separate commit). Also the code gets somewhat simplified - instead of `memcmp(ip, pchIPv4, sizeof(pchIPv4)) == 0` we can use `m_net == NET_IPV4`. Co-authored-by: Carl Dong <contact@carldong.me>

2020-07-03Replace automatic bans with discouragement filterPieter Wuille
This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full. Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers. Also change the name of this mechanism to better reflect reality; they're not banned, just discouraged. Contains release notes and several interface improvements by John Newbery.
