2021-08-05Rate limit the processing of incoming addr messagesPieter Wuille
While limitations on the influence of attackers on addrman already exist (affected buckets are restricted to a subset based on incoming IP / network group), there is no reason to permit them to let them feed us addresses at more than a multiple of the normal network rate. This commit introduces a "token bucket" rate limiter for the processing of addresses in incoming ADDR and ADDRV2 messages. Every connection gets an associated token bucket. Processing an address in an ADDR or ADDRV2 message from non-whitelisted peers consumes a token from the bucket. If the bucket is empty, the address is ignored (it is not forwarded or processed). The token counter increases at a rate of 0.1 tokens per second, and will accrue up to a maximum of 1000 tokens (the maximum we accept in a single ADDR or ADDRV2). When a GETADDR is sent to a peer, it immediately gets 1000 additional tokens, as we actively desire many addresses from such peers (this may temporarily cause the token count to exceed 1000). The rate limit of 0.1 addr/s was chosen based on observation of honest nodes on the network. Activity in general from most nodes is either 0, or up to a maximum around 0.025 addr/s for recent Bitcoin Core nodes. A few (self-identified, through subver) crawler nodes occasionally exceed 0.1 addr/s. Github-Pull: #22387 Rebased-From: 0d64b8f709b4655d8702f810d4876cd8d96ded82

2021-05-22p2p, bugfix: use NetPermissions::HasFlag() in CConnman::Bind()Jon Atack
PF_NOBAN is a multi-flag that includes PF_DOWNLOAD, so the conditional in CConnman::Bind() using a bitwise AND will return the same result for both the "noban" status and the "download" status. Example: `PF_DOWNLOAD` is `0b1000000` `PF_NOBAN` is `0b1010000` This makes a check like `flags & PF_NOBAN` return `true` even if `flags` is equal to `PF_DOWNLOAD`. If `-whitebind=download@1.1.1.1:8765` is specified, then `1.1.1.1:8765` should be added to the list of local addresses. We only want to avoid adding to local addresses (that are advertised) a whitebind that has a `noban@` flag. As a result of a mis-check in `CConnman::Bind()` we would not have added `1.1.1.1:8765` to the local addresses in the example above.

2021-04-16test: use pointers in denialofservice_tests/peer_discouragementVasil Dimov
This is a non-functional change that replaces the `CNode` on-stack variables with `CNode` pointers. The reason for this is that it would allow us to add those `CNode`s to `CConnman::vNodes[]` which in turn would allow us to check that they are disconnected properly - a `CNode` object must be in `CConnman::vNodes[]` in order for its `fDisconnect` flag to be set. If we store pointers to the on-stack variables in `CConnman` then it would crash at the end, trying to `delete` them. Github-Pull: #21571 Rebased-From: 4d6e246fa46f2309e2998b542e4c104d73d29071

One conflict was in the test case. ACKs for top commit: ajtowns: ACK 5a2d98c640cf308d3c7e85ba51fbb7e84f99322a -- checked 'rebased-from' patches are in master, and rebased patches are clean rebases (except for the first one which changes `""s` to `std::string("")` to avoid c++17 dependency). commits seem fine, but haven't reviewed in detail. fanquake: ACK 5a2d98c640cf308d3c7e85ba51fbb7e84f99322a - branched off `0.21` and redid the backports. Minor conflict in c33fbab25c82b6a18773b80e8b355c987066ae5a. The diff between my branch and #20901 was just in release notes, `_CLIENT_VERSION_RC` (#20901 branched before 95ea54ba089610019a74c1176a2c7c0dba144b1c) and #21490 which has already been merged into `0.21`.
