We have a bloom filter of recently rejected transactions, whose purpose is to help us avoid redownloading and revalidating transactions that fail to be accepted, but because of this potential for witness malleability to interfere with relay of valid transactions, we do not use the filter for segwit transactions. This issue is discussed at some length in #8279. The effect of this is that whenever a segwit transaction that fails policy checks is relayed, a node would download that transaction from every peer announcing it, because it has no way presently to cache failure. Historically this hasn't been a big problem, but if/when policy for accepting segwit transactions were to change (eg taproot, or any other change), we could expect older nodes talking to newer nodes to be wasting bandwidth because of this. As discussed in that issue, switching to wtxid-based relay solves this problem -- by using an identifier for a transaction that commits to all the data in our relay protocol, we can be certain if a transaction that a peer is announcing is one that we've already tried to process, or if it's something new. This PR introduces support for wtxid-based relay with peers that support it (and remains backwards compatible with peers that use txids for relay, of course). Apart from code correctness, one issue to be aware of is that by downloading from old and new peers alike, we should expect there to be some bandwidth wasted, because sometimes we might download the same transaction via txid-relay as well as wtxid-relay. The last commit in this PR implements a heuristic I want to analyze, which is to just delay relay from txid-relay peers by 2 seconds, if we have at least 1 wtxid-based peer. I've just started running a couple nodes with this heuristic so I can measure how well it works, but I'm open to other ideas for minimizing that issue. In the long run, I think this will be essentially a non-issue, so I don't think it's too big a concern, we just need to bite the bullet and deal with it during upgrade. Finally, this proposal would need a simple BIP describing the changes, which I haven't yet drafted. However, review and testing of this code in the interim would be welcome. To do items: - [x] Write BIP explaining the spec here (1 new p2p message for negotiating wtxid-based relay, along with a new INV type) - [ ] Measure and evaluate a heuristic for minimizing how often a node downloads the same transaction twice, when connected to old and new nodes.

This is problematic for several reasons: * Submitting a blockheader that fails `CheckBlockHeader` over RPC will result in a debug log line that starts with `ERROR`. Proper behaviour should be to log not anything and instead only return the failure reason to the RPC user. This pull does not fix this issue entirely, but is a good first step in the right direction. * A misbehaving peer that sends us an invalid block header that fails `CheckBlockHeader` will result in a debug log line that starts with `ERROR`. Proper behavior should be to log the remote peer misbehavior if logging for that category was enabled. This pull fixes this issue for `CheckBlockHeader` and other functions can be adjusted as well if needed in follow-ups. This should be a good first step in the right direction.

In net.h and init.cpp, `MAX_BLOCKS_ONLY_CONNECTIONS` is used to represent the maximum number of `block-relay-only` outbound peers, which is 2.

4455949d6f0218b40d33d7fe6de6555f8f62192f Make test DoS_mapOrphans deterministic (David Reikher) Pull request description: This pull request proposes a solution to make the test `DoS_mapOrphans` in denialofservice_tests.cpp have deterministic coverage. The `RandomOrphan` function in denialofservice_tests.cpp and the implicitly called function `ecdsa_signature_parse_der_lax` in pubkey.cpp were causing the non-deterministic test coverage. In the former, if a random orphan was selected the index of which is bigger than the max. orphan index in `mapOrphanTransactions`, the last orphan was returned from `RandomOrphan`. If the random number generated was never large enough, this condition would not be fulfilled and the corresponding branch wouldn't run. The proposed solution is to force one of the 50 dependant orphans to depend on the last orphan in `mapOrphanTransactions` using the newly introduced function `OrphanByIndex` (and passing it a large uint256), forcing this branch to run at least once. In the latter, if values for ECDSA `R` or `S` (or both) had no leading zeros, some code would not be executed. The solution was to find a constant signature that would be comprised of `R` and `S` values with leading zeros and calling `CPubKey::Verify` at the end of the test with this signature forcing this code to always run at least once at the end even if it hadn't throughout the test. To test that the coverage is (at least highly likely) deterministic, I ran `contrib/devtools/test_deterministic_coverage.sh denialofservice_tests/DoS_mapOrphans 1000` and the result was deterministic coverage across 1000 runs. Also - removed denialofservice_tests test entry from the list of non-deterministic tests in the coverage script.

2020-07-21Make test DoS_mapOrphans deterministicDavid Reikher
The RandomOrphan function and the function ecdsa_signature_parse_der_lax in pubkey.cpp were causing non-deterministic test coverage. Force seed in the beginning of the test to make it deterministic. The seed is selected carefully so that all branches of the function ecdsa_signature_parse_der_lax are executed. Prior to this fix, the test was exhibiting non-deterministic coverage since none of the ECDSA signatures that were generated during the test had leading zeroes in either R, S, or both, resulting in some branches of said function not being executed. The seed ensures that both conditions are hit. Removed denialofservice_tests test entry from the list of non-deterministic tests in the coverage script.

2020-07-19Make TX_WITNESS_STRIPPED its own rejection reasonSuhas Daftuar
Previously, TX_WITNESS_MUTATED could be returned during transaction validation for either transactions that had a witness that was non-standard, or for transactions that had no witness but were invalid due to segwit validation rules. However, for txid/wtxid-relay considerations, net_processing distinguishes the witness stripped case separately, because it affects whether a wtxid should be able to be added to the reject filter. It is safe to add the wtxid of a witness-mutated transaction to the filter (as that wtxid shouldn't collide with the txid, and hence it wouldn't interfere with transaction relay from txid-relay peers), but it is not safe to add the wtxid (== txid) of a witness-stripped transaction to the filter, because that would interfere with relay of another transaction with the same txid (but different wtxid) when relaying from txid-relay peers. Also updates the comment explaining this logic, and explaining that we can get rid of this complexity once there's a sufficient deployment of wtxid-relaying peers on the network.
2020-07-19Delay getdata requests from peers using txid-based relaySuhas Daftuar
Using both txid and wtxid-based relay with peers means that we could sometimes download the same transaction twice, if announced via two different hashes from different peers. Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have at least one wtxid-based peer.

This adds a field to CNodeState that tracks whether to relay transactions with that peer via wtxid, instead of txid. As of this commit the field will always be false, but in a later commit we will add a way to negotiate turning this on via p2p messages exchanged with the peer.
2020-07-18Add wtxids to recentRejects instead of txidsSuhas Daftuar
Previously, we only added txids to recentRejects if we were sure that the transaction couldn't have had the wrong witness (either because the witness was malleated or stripped). In preparation for wtxid-based relay, we can observe that txid == wtxid for transactions that have no witness, and add the wtxid of rejected transactions, provided the transaction wasn't a witness-stripped one. This means that we now add more data to the filter (as prior to this commit, any transaction with a witness that failed to be accepted was being skipped for inclusion in the filter) but witness malleation should still not interfere with relay of a valid segwit transaction, because the txid of a segwit transaction would not be added to the filter after failing validation. In the future, having wtxids in the recent rejects filter will allow us to skip downloading the same wtxid multiple times, once our peers use wtxids for transaction relay.
2020-07-18Add wtxids of confirmed transactions to bloom filterSuhas Daftuar
This is in preparation for wtxid-based invs (we need to be able to tell whether we AlreadyHave() a transaction based on either txid or wtxid). This also double the size of the bloom filter, which is overkill, but still uses a manageable amount of memory.
