252675e Do not send witnesses in cmpctblock (Pieter Wuille)
2016-07-12Improve handling of unconnecting headersSuhas Daftuar
When processing a headers message that looks like a block announcement, send peer a getheaders if the headers message won't connect. Apply DoS points after too many consecutive unconnecting headers messages.
2016-07-07Fix DoS vulnerability in mempool acceptanceSuhas Daftuar
Moves the IsStandard check to happen after the premature-witness check, so that adding a witness to a transaction can't prevent mempool acceptance. Note that this doesn't address the broader category of potential mempool DoS issues that affect transactions after segwit activation.

This reverts commit f93c2a1b7ee912f0651ebb4c8a5eca220e434f4a. This can cause synchronization to get stuck.

2016-06-20Merge #8179: Evict orphans which are included or precluded by accepted blocks.Wladimir J. van der Laan
54326a6 Increase maximum orphan size to 100,000 bytes. (Gregory Maxwell) 8c99d1b Treat orphans as implicit inv for parents, discard when parents rejected. (Gregory Maxwell) 11cc143 Adds an expiration time for orphan tx. (Gregory Maxwell) db0ffe8 This eliminates the primary leak that causes the orphan map to always grow to its maximum size.

2016-06-19If AcceptBlockHeader returns true, pindex will be set.Matt Corallo
Assert this instead of checking (and then dref'ing later anyway) to make sure no one thinks they can change that postcondition of AcceptBlockHeader..
2016-06-16Merge #8084: Add recently accepted blocks and txn to AttemptToEvictConnection.Wladimir J. van der Laan
6ee7f05 Allow disconnecting a netgroup with only one member in eviction. (Gregory Maxwell) 5d0ca81 Add recently accepted blocks and txn to AttemptToEvictConnection. (Gregory Maxwell)
2016-06-15Add recently accepted blocks and txn to AttemptToEvictConnection.Gregory Maxwell
This protects any not-already-protected peers who were the most recent four to relay transactions and most recent four to send blocks to us.
2016-06-15Increase maximum orphan size to 100,000 bytes.Gregory Maxwell
Although this increases node memory usage in the worst case by perhaps 30MB, the current behavior causes severe issues with dependent tx relay.
2016-06-15Treat orphans as implicit inv for parents, discard when parents rejected.Gregory Maxwell
An orphan whos parents were rejected is never going to connect, so there is little utility in keeping it. Orphans also helpfully tell us what we're missing, so go ahead and treat it as INVed.
2016-06-15Adds an expiration time for orphan tx.Gregory Maxwell
This prevents higher order orphans and other junk from holding positions in the orphan map. Parents delayed twenty minutes are more are unlikely to ever arrive. The freed space will improve the orphan matching success rate for other transactions.
2016-06-14Remove bad chain alert partition checkBtcDrak
As per meeting 2016-03-31 https://bitcoincore.org/en/meetings/2016/03/31/#bad-chain-alerts The partition checker was producing huge number of false-positives and was disabled in 0.12.1 on the understanding it would either be fixed in 0.13 or removed entirely from master if not.

2016-06-10This eliminates the primary leak that causes the orphan map toGregory Maxwell
always grow to its maximum size. This does not go so far as to attempt to connect orphans made connectable by a new block. Keeping the orphan map less full helps improve the reliability of relaying chains of transactions.

2016-06-06drop vAddrToSend after sending big addr messageKaz Wesley
We send a newly-accepted peer a 1000-entry addr message, and then only use vAddrToSend for small messages. Deallocate vAddrToSend after it's been used for the big message to save about 40 kB per connected inbound peer.
