2016-07-26Ignore CMPCTBLOCK messages for pruned blocksSuhas Daftuar
Also ignores CMPCTBLOCK announcements that have too little work. This is to prevent disk-exhaustion DoS.
2016-07-26Ignore GETBLOCKTXN requests for unknown blocksSuhas Daftuar
Don't disconnect peers, or else we leak information that could be used for fingerprinting.

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.

2016-07-05Revert "net: Avoid duplicate getheaders requests." PR #8054Gregory Maxwell
This reverts commit f93c2a1b7ee912f0651ebb4c8a5eca220e434f4a. This can cause synchronization to get stuck.
2016-06-27util: Remove zero-argument versions of LogPrint and errorWladimir J. van der Laan
Changes in tinyformat, recently imported from upstream have made the zero-argument versions of formatting functions unnecessary. Remove them. This is a slight semantic change: `%` characters in the zero-argument call are now regarded and need to be escaped. As for as I know, the only use of this is in `main.cpp`.

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.
