2021-08-04[net_processing] Provide debug error if code assumptions change.Amiti Uttarwar
Currently, this call to SetupAddressRelay will never return false because of the previous guard that returns early if the peer is not an inbound connection. Rather than implicitly relying on this guarantee, throw an error in the debug build if it ever changes.

This PR aims to reduce addr blackholes. When we receive an `addr` message that contains 10 or less addresses, we forward them to 1-2 peers. This is the main technique we use for self advertisements, so sending to peers that wouldn't relay would effectively "blackhole" the trickle. Although we cannot prevent this in a malicious case, we can improve it for the normal, honest cases, and reduce the overall likelihood of occurrence. Two known cases where peers would not participate in addr relay are if they have connected to you as a block-relay-only connection, or if they are a light client. This implementation defers initialization of `m_addr_known` until it is needed, then uses its presence to decide if the peer is participating in addr relay. For outbound (not block-relay-only) peers, we initialize the filter before sending the initial self announcement when processing their `version` message. For inbound peers, we initialize the filter if/when we get an addr related message (`ADDR`, `ADDRV2`, `GETADDR`). We do NOT initialize the filter based on a `SENDADDRV2` message. To communicate about these changes beyond bitcoin core & to (try to) ensure that no other software would be disrupted, I have: - Posted to the [mailing list](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-April/018784.html) - Researched other open source clients to confirm compatibility, opened issues in all the projects & documented in https://github.com/bitcoin/bitcoin/pull/21528#issuecomment-809906430.

2021-07-29[net_processing] Defer initializing m_addr_knownAmiti Uttarwar
Use SetupAddressRelay to only initialize `m_addr_known` as needed. For outbound peers, we initialize the filter before sending our self announcement (not applicable for block-relay-only connections). For inbound peers, we initialize the filter when we get an addr related message (ADDR, ADDRV2, GETADDR). These changes intend to mitigate address blackholes. Since an inbound peer has to send us an addr related message to become eligible as a candidate for addr relay, this should reduce our likelihood of sending them self-announcements.

This is done by disconnecting after receiving the first `addr`. However, it is no longer working as intended, because nowadays, the first `addr` a typical bitcoin core node sends is its self-announcement. So we'll disconnect before the peer gets a chance to answer our `getaddr`. I checked that this affects both `-seednode` peers specified manually, and DNS seeds when AddrFetch is used as a fallback if DNS doesn't work for us. The current behavior of getting peers via AddrFetch when starting with an empty addrman would be to connect to the peer, receive its self-announcement and add it to addrman, disconnect, reconnect to the same peer again as a full outbound (no other addresses in addrman) and then receive more `addr`. This is silly and not in line with AddrFetch peer being intended to be short-lived peers.  Fix this by only disconnecting after receiving an `addr` message of size > 1. [Edit] As per review discussion, this PR now also adds a timeout after which we disconnect if we haven't received any suitable `addr`, and a functional test.

2021-07-15Rate 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.

2021-06-03Protect last outbound HB compact block peerSuhas Daftuar
If all our high-bandwidth compact block serving peers (BIP 152) stall block download, then we can be denied a block for (potentially) a long time. As inbound connections are much more likely to be adversarial than outbound connections, mitigate this risk by never removing our last outbound HB peer if it would be replaced by an inbound.

MarkBlockAsReceived() should not be used for both removing the block from mapBlocksInFlight and checking whether it was in the map.

2021-06-03[net processing] Remove CNodeState.nBlocksInFlightValidHeadersJohn Newbery
nBlocksInFlightValidHeaders always has the same value as nBlocksInFlight, since we only download blocks with valid headers.
2021-06-03[net processing] Remove QueuedBlock.fValidatedHeadersJohn Newbery
Since headers-first syncing, we only ever request a block if we've already validated its headers. Therefore QueuedBlock.fValidatedHeaders is always set to true. Remove it.
2021-06-03[net processing] Remove unnecessary hash arg from MarkBlockAsInFlight()John Newbery
MarkBlockAsInFlight is always called with a non-null pindex. Just get the block hash from that pindex inside the function.

2021-05-28p2p: AddrFetch - don't disconnect on self-announcementsMartin Zumsande
Disconnecting an AddrFetch peer only after receiving an addr message of size >1 prevents dropping them before they had a chance to answer the getaddr request.

Checking this option for every peer on every iteration of the message handler is unnecessary, as described in #21545. refactor: Move feefilter logic out into a separate `MaybeSendFeefilter(...)` function to improve readability of the already long `SendMessages(...)`. fixes #21545 The configuration option `-feefilter` has been added in 9e072a6e66efbda7d39bf61eded21d2b324323be: _"Implement "feefilter" P2P message"_ According to the [BIP133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki), turning the fee filter off was ment for: > [...] a node [...] using prioritisetransaction to accept transactions whose actual fee rates might fall below the node's mempool min fee [in order to] disable the fee filter to make sure it is exposed to all possible txid's `-feefilter` was subsequently set as debug only in #8150, with the motivation that the help message was too difficult to translate.
