|/ | | | | | | | | | | | | | If the peer (whether pruned or not itself) supports sending pruned blocks to syncing nodes, the pruned version will be sent along with the hash of the pruned data and the block weight. The original tx hashes can be reconstructed from the pruned txes and theur prunable data hash. Those hashes and the block weights are hashes and checked against the set of precompiled hashes, ensuring the data we received is the original data. It is currently not possible to use this system when not using the set of precompiled hashes, since block weights can not otherwise be checked for validity. This is off by default for now, and is enabled by --sync-pruned-blocks

* cryptonote_protocol_handler: prevent potential DoSanonimal2019-06-141-0/+1
| | | | | | | | | | Essentially, one can send such a large amount of IDs that core exhausts all free memory. This issue can theoretically be exploited using very large CN blockchains, such as Monero. This is a partial fix. Thanks and credit given to CryptoNote author 'cryptozoidberg' for collaboration and the fix. Also thanks to 'moneromooo'. Referencing HackerOne report #506595.

| * cryptonote_protocol_handler: search for syncing peers in "cruise mode"moneromooo-monero2019-02-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | When all our outgoing peer slots are filled, we cycle one peer at a time looking for syncing peers until we have at least two such peers. This brings two advantages: - Peers without incoming connections will find more syncing peers that before, thereby strengthening network decentralization - Peers will have more resistance to isolation attacks, as they are more likely to find a "good" peer than they were before

* Pruningmoneromooo-monero2019-01-221-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The blockchain prunes seven eighths of prunable tx data. This saves about two thirds of the blockchain size, while keeping the node useful as a sync source for an eighth of the blockchain. No other data is currently pruned. There are three ways to prune a blockchain: - run monerod with --prune-blockchain - run "prune_blockchain" in the monerod console - run the monero-blockchain-prune utility The first two will prune in place. Due to how LMDB works, this will not reduce the blockchain size on disk. Instead, it will mark parts of the file as free, so that future data will use that free space, causing the file to not grow until free space grows scarce. The third way will create a second database, a pruned copy of the original one. Since this is a new file, this one will be smaller than the original one. Once the database is pruned, it will stay pruned as it syncs. That is, there is no need to use --prune-blockchain again, etc.

* cryptonote_protocol: misc fixes to the new sync algorithmmoneromooo-monero2017-08-211-0/+2
| | | | | | | | | | | Fix sync wedge corner case: It could happen if a connection went into standby mode, while it was the one which had requested the next span, and that span was still waiting for the data, and that peer is not on the main chain. Other peers can then start asking for that data again and again, but never get it as only that forked peer does. And various other fixes
