2024-03-08Fixed mempool pruningSChernykh2-7/+19
- Fixed undefined behavior after a call to `remove_tx_from_transient_lists` (it used an invalid iterator) - Fixed `txCompare` (it wasn't strictly weak ordered)
2024-03-08get_block_template_backlog: better sorting logicSChernykh1-1/+1
std::sort is unstable, so it can return random sets of transactions when mempool has many transactions with the same fee/byte. It can result in p2pool mining empty blocks sometimes because it doesn't pick up "new" transactions immediately.
2024-03-07tx_memory_pool: make double spends a no-drop offensejeffro2561-0/+1
Nodes who see different txs in a double spend attack will drop each other, splitting the network. Issue found by @boog900.

2023-03-07Enforce restricted # pool txs served via RPC + optimize chunked reqsj-berman5-37/+74
- `/getblocks.bin` respects the `RESTRICTED_TX_COUNT` (=100) when returning pool txs via a restricted RPC daemon. - A restricted RPC daemon includes a max of `RESTRICTED_TX_COUNT` txs in the `added_pool_txs` field, and returns any remaining pool hashes in the `remaining_added_pool_txids` field. The client then requests the remaining txs via `/gettransactions` in chunks. - `/gettransactions` no longer does expensive no-ops for ALL pool txs if the client requests a subset of pool txs. Instead it searches for the txs the client explicitly requests. - Reset `m_pool_info_query_time` when a user: (1) rescans the chain (so the wallet re-requests the whole pool) (2) changes the daemon their wallets points to (a new daemon would have a different view of the pool) - `/getblocks.bin` respects the `req.prune` field when returning pool txs. - Pool extension fields in response to `/getblocks.bin` are optional with default 0'd values.

2023-01-09Refactored rx-slow-hash.cSChernykh4-43/+41
- Straight-forward call interface: `void rx_slow_hash(const char *seedhash, const void *data, size_t length, char *result_hash)` - Consensus chain seed hash is now updated by calling `rx_set_main_seedhash` whenever a block is added/removed or a reorg happens - `rx_slow_hash` will compute correct hash no matter if `rx_set_main_seedhash` was called or not (the only difference is performance) - New environment variable `MONERO_RANDOMX_FULL_MEM` to force use the full dataset for PoW verification (faster block verification) - When dataset is used for PoW verification, dataset updates don't stall other threads (verification is done in light mode then) - When mining is running, PoW checks now also use dataset for faster verification

2022-09-22Move update_checkpoints() to a later stageSChernykh1-4/+0
update_checkpoints() makes a few DNS requests and can take up to 20-30 seconds to complete (3-6 seconds on average). It is currently called from core::handle_incoming_block() which holds m_incoming_tx_lock, so it blocks all incoming transactions and blocks processing while update_checkpoints() is running. This PR moves it to until after a new block has been processed and relayed, to avoid full monerod locking.

2022-07-26Fixed get_block_template_backlog performanceSChernykh2-17/+56
Before the fix, it processed all transactions in the mempool which could be very slow when mempool grows to several MBs in size. I observed `get_block_template_backlog` taking up to 15 seconds of CPU time under high mempool load. After the fix, only transactions that can potentially be mined in the next block will be processed (a bit more than the current block median weight).

2022-04-18Add view tags to outputs to reduce wallet scanning timej-berman5-32/+62
Implements view tags as proposed by @UkoeHB in MRL issue https://github.com/monero-project/research-lab/issues/73 At tx construction, the sender adds a 1-byte view tag to each output. The view tag is derived from the sender-receiver shared secret. When scanning for outputs, the receiver can check the view tag for a match, in order to reduce scanning time. When the view tag does not match, the wallet avoids the more expensive EC operations when deriving the output public key using the shared secret.

This comment suggests this check is unnecessary, when it is completely necessary as miner TXs can have multiple outputs *which is a statement directly, and incorrectly, contradicted by this comment*. While I don't ever see someone removing this code and getting their edits merged into Monero, someone inexperienced who thinks they're cleaning old code may break their own work, and then there's really just zero benefit to keeping this around.

2021-03-05fix serialization being different on macmoneromooo-monero1-2/+2
On Mac, size_t is a distinct type from uint64_t, and some types (in wallet cache as well as cold/hot wallet transfer data) use pairs/containers with size_t as fields. Mac would save those as full size, while other platforms would save them as varints. Might apply to other platforms where the types are distinct. There's a nasty hack for backward compatibility, which can go after a couple forks.
2021-02-09Remove unused variables in monero codebaseKevin Barbour2-3/+0
There are quite a few variables in the code that are no longer (or perhaps never were) in use. These were discovered by enabling compiler warnings for unused variables and cleaning them up. In most cases where the unused variables were the result of a function call the call was left but the variable assignment removed, unless it was obvious that it was a simple getter with no side effects.

2020-11-17Change Dandelion++ fluff probability to 20%, and embargo timeout to 39sLee Clagett1-2/+2
A 20% fluff probability increases the precision of a spy connected to every node by 10% on average, compared to a network using 0% fluff probability. The current value (10% fluff) should increase precision by ~5% compared to baseline. This decreases the expected stem length from 10 to 5. The embargo timeout was therefore lowered to 39s; the fifth node in a stem is expected to have a 90% chance of being the first to timeout, which is the same probability we currently have with an expected stem length of 10 nodes.

Miners with MLSAG txes which they'd already verified included a couple in that block, but the consensus rules had changed in the meantime, so that block is technically invalid and any node which did not already have those two txes in their txpool could not sync. Grandfather them in, since it has no effect in practice.

2020-07-08blockchain: fix timestamp/difficulty cache getting out of syncmoneromooo-monero2-1/+17
The cache is discarded when a block is popped, but then gets rebuilt when the difficulty for next block is requested. While this is all properly locked, it does not take into account the delay caused by a database transaction being only committed (and thus its effects made visible to other threads) later on, which means another thread could request difficulty between the pop and the commit, which would end up using stale database view to build the cache, but that cache would not be invalidated again when the transaction gets committed, which would cause the cache to not match the new database data. To fix this, we now keep track of when the cache is invalidated so we can invalidate it again upon database transaction commit to ensure it gets calculated again with fresh data next time it is nedeed.

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

2019-08-28Fix bug in mempool get_transaction_stats histogram calculationTom Smeding1-3/+10
The 98th percentile position in the agebytes map was incorrectly calculated: it assumed the transactions in the mempool all have unique timestamps at second-granularity. This commit fixes this by correctly finding the right cumulative number of transactions in the map suffix. This bug could lead to an out-of-bounds write in the rare case that all transactions in the mempool were received (and added to the mempool) at a rate of at least 50 transactions per second. (More specifically, the number of *unique* receive_time values, which have second- granularity, must be at most 2% of the number of transactions in the mempool for this crash to trigger.) If this condition is satisfied, 'it' points to *before* the agebytes map, 'delta' gets a nonsense value, and the value of 'i' in the first stats.histo-filling loop will be out of bounds of stats.histo.

2019-08-15Replace std::random_shuffle with std::shuffleTom Smeding1-1/+1
According to [1], std::random_shuffle is deprecated in C++14 and removed in C++17. Since std::shuffle is available since C++11 as a replacement and monero already requires C++11, this is a good replacement. A cryptographically secure random number generator is used in all cases to prevent people from perhaps copying an insecure std::shuffle call over to a place where a secure one would be warranted. A form of defense-in-depth. [1]: https://en.cppreference.com/w/cpp/algorithm/random_shuffle
