lock order assertion 9b85a5e2f7e003ca8621feaac9bdd304d19081b4 tests: Test for dumpwallet lock order issue (Andrew Chow) 25d99e6511d8c43b2025a89bcd8295de755346a7 Reorder dumpwallet so that cs_main functions go first (Andrew Chow) Pull request description: When a wallet is loaded which has an unconfirmed transaction in the mempool, it will end up establishing the lock order of cs_wallet -> cs_main -> cs_KeyStore. If `dumpwallet` is used on this wallet, then a lock order of cs_wallet -> cs_KeyStore -> cs_main will be used, which causes a lock order assertion. This PR fixes this by reordering `dumpwallet` and `GetKeyBirthTimes` (only used by `dumpwallet`). Specifically, in both functions, the function calls which lock cs_main are done prior to locking cs_KeyStore. This avoids the lock order issue. Additionally, I have added a test case to `wallet_dump.py`. Of course testing this requires `--enable-debug`.

Only add a transaction to the unbroadcast set when it's added to the mempool Currently, if BroadcastTransaction() is called to rebroadcast a transaction (e.g. by ResendWalletTransactions()), then we add the transaction to the unbroadcast set. That transaction has already been broadcast in the past, so peers are unlikely to request it again, meaning RemoveUnbroadcastTx() won't be called and it won't be removed from m_unbroadcast_txids. Net processing will therefore continue to attempt rebroadcast for the transaction every 10-15 minutes. This will most likely continue until the node connects to a new peer which hasn't yet seen the transaction (or perhaps indefinitely). Fix by only adding the transaction to the broadcast set when it's added to the mempool. 2. Allow rebroadcast for same-txid-different-wtxid transactions There is some slightly unexpected behaviour when: - there is already transaction in the mempool (the "mempool tx") - BroadcastTransaction() is called for a transaction with the same txid as the mempool transaction but a different witness (the "new tx") Prior to this commit, if BroadcastTransaction() is called with relay=true, then it'll call RelayTransaction() using the txid/wtxid of the new tx, not the txid/wtxid of the mempool tx. For wtxid relay peers, in SendMessages(), the wtxid of the new tx will be taken from setInventoryTxToSend, but will then be filtered out from the vector of wtxids to announce, since m_mempool.info() won't find the transaction (the mempool contains the mempool tx, which has a different wtxid from the new tx). Fix this by calling RelayTransaction() with the wtxid of the mempool transaction in this case. The third commit is a comment/whitespace only change to tidy up the BroadcastTransaction() function.

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.

2021-07-19Reorder dumpwallet so that cs_main functions go firstAndrew Chow
DEBUG_LOCKORDER expects cs_wallet, cs_main, and cs_KeyStore to be acquired in that order. However dumpwallet would take these in the order cs_wallet, cs_KeyStore, cs_main. So when configured with `--enable-debug`, it is possible to hit the lock order assertion when using dumpwallet. To fix this, cs_wallet and cs_KeyStore are no longer locked at the same time. Instead cs_wallet will be locked first. Then the functions which lock cs_main will be run. Lastly cs_KeyStore will be locked afterwards. This avoids the lock order issue. Furthermore, since GetKeyBirthTimes (only used by dumpwallet) also uses a function that locks cs_main, and itself also locks cs_KeyStore, the same reordering is done here.

However, the current codebase will happily accept and process an effectively unbounded rate from attackers. There are measures to limit the influence attackers can have on the addrman database (bucket restrictions based on source IPs), but still - there is no need to permit them to feed us addresses at a rate that's orders of magnitude larger than what is common on the network today, especially as it will cause us to spam our peers too. This PR implements a [token bucket](https://en.wikipedia.org/wiki/Token_bucket) based rate limiter, allowing an average of 0.1 addr/s per connection, with bursts up to 1000 addresses at once. Whitelisted peers as well as responses to GETADDR requests are exempt from the limit. New connections start with 1 token, so as to not interfere with the common practice of peers' self-announcement.

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.

2021-07-09[mempool] Allow rebroadcast for same-txid-different-wtxid transactionsJohn Newbery
This commit fixes some slightly unexpected behaviour when: - there is already transaction in the mempool (the "mempool tx") - BroadcastTransaction() is called for a transaction with the same txid as the mempool transaction but a different witness (the "new tx") Prior to this commit, if BroadcastTransaction() is called with relay=true, then it'll call RelayTransaction() using the txid/wtxid of the new tx, not the txid/wtxid of the mempool tx. For wtxid relay peers, in SendMessages(), the wtxid of the new tx will be taken from setInventoryTxToSend, but will then be filtered out from the vector of wtxids to announce, since m_mempool.info() won't find the transaction (the mempool contains the mempool tx, which has a different wtxid from the new tx). Fix this by calling RelayTransaction() with the wtxid of the mempool transaction in this case.
2021-07-09[mempool] Only add a transaction to the unbroadcast set when it's added to ↵John Newbery
the mempool Currently, if BroadcastTransaction() is called to rebroadcast a transaction (e.g. by ResendWalletTransactions()), then we add the transaction to the unbroadcast set. That transaction has already been broadcast in the past, so peers are unlikely to request it again, meaning RemoveUnbroadcastTx() won't be called and it won't be removed from m_unbroadcast_txids. Net processing will therefore continue to attempt rebroadcast for the transaction every 10-15 minutes. This will most likely continue until the node connects to a new peer which hasn't yet seen the transaction (or perhaps indefinitely). Fix by only adding the transaction to the broadcast set when it's added to the mempool.

2021-07-09addrman: reset I2P ports to 0 when loading from diskVasil Dimov
This is a temporary change to convert I2P addresses that have propagated with port 8333 to ones with port 0. It would cause a problem some day if indeed some bitcoin software is listening on port 8333 only and rejects connections to port 0 and we are still using SAM 3.1 which only supports port 0. In this case we would replace 8333 with 0 and try to connect to such nodes. This commit should be included in 22.0 and be reverted before 23.0 is released.
2021-07-09net: do not connect to I2P hosts on port!=0Vasil Dimov
When connecting to an I2P host we don't specify destination port and it is being forced to 0 by the SAM 3.1 proxy, so if we connect to the same host on two different ports, that would be actually two connections to the same service (listening on port 0). Fixes https://github.com/bitcoin/bitcoin/issues/21389

* 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.
