-Checkpoint-admin is a tool for updating checkpoint oracle status. It provides a series of functions including deploying checkpoint oracle contract, signing for new checkpoints, and updating checkpoints in the checkpoint oracle contract. - -### Checkpoint - -In the LES protocol, there is an important concept called checkpoint. In simple terms, whenever a certain number of blocks are generated on the blockchain, a new checkpoint is generated which contains some important information such as - -* Block hash at checkpoint -* Canonical hash trie root at checkpoint -* Bloom trie root at checkpoint - -*For a more detailed introduction to checkpoint, please see the LES [spec](https://github.com/ethereum/devp2p/blob/master/caps/les.md).* - -Using this information, light clients can skip all historical block headers when synchronizing data and start synchronization from this checkpoint. Therefore, as long as the light client can obtain some latest and correct checkpoints, the amount of data and time for synchronization will be greatly reduced. - -However, from a security perspective, the most critical step in a synchronization algorithm based on checkpoints is to determine whether the checkpoint used by the light client is correct. Otherwise, all blockchain data synchronized based on this checkpoint may be wrong. For this we provide two different ways to ensure the correctness of the checkpoint used by the light client. - -#### Hardcoded checkpoint - -There are several hardcoded checkpoints in the [source code](https://github.com/ethereum/go-ethereum/blob/master/params/config.go#L38) of the go-ethereum project. These checkpoints are updated by go-ethereum developers when new versions of software are released. Because light client users trust Geth developers to some extent, hardcoded checkpoints in the code can also be considered correct. - -#### Checkpoint oracle - -Hardcoded checkpoints can solve the problem of verifying the correctness of checkpoints (although this is a more centralized solution). But the pain point of this solution is that developers can only update checkpoints when a new version of software is released. In addition, light client users usually do not keep the Geth version they use always up to date. So hardcoded checkpoints used by users are generally stale. Therefore, it still needs to download a large amount of blockchain data during synchronization. - -Checkpoint oracle is a more flexible solution. In simple terms, this is a smart contract that is deployed on the blockchain. The smart contract records several designated trusted signers. Whenever enough trusted signers have issued their signatures for the same checkpoint, it can be considered that the checkpoint has been authenticated by the signers. Checkpoints authenticated by trusted signers can be considered correct. - -So this way, even without updating the software version, as long as the trusted signers regularly update the checkpoint in oracle on time, the light client can always use the latest and verified checkpoint for data synchronization. - -### Usage - -Checkpoint-admin is a command line tool designed for checkpoint oracle. Users can easily deploy contracts and update checkpoints through this tool. - -#### Install - -```shell -go get github.com/ethereum/go-ethereum/cmd/checkpoint-admin -``` - -#### Deploy - -Deploy checkpoint oracle contract. `--signers` indicates the specified trusted signer, and `--threshold` indicates the minimum number of signatures required by trusted signers to update a checkpoint. - -```shell -checkpoint-admin deploy --rpc --clef --signer --signers --threshold 1 -``` - -It is worth noting that checkpoint-admin only supports clef as a signer for transactions and plain text(checkpoint). For more clef usage, please see the clef [tutorial](https://geth.ethereum.org/docs/clef/tutorial) . - -#### Sign - -Checkpoint-admin provides two different modes of signing. You can automatically obtain the current stable checkpoint and sign it interactively, and you can also use the information provided by the command line flags to sign checkpoint offline. - -**Interactive mode** - -```shell -checkpoint-admin sign --clef --signer --rpc -``` - -*It is worth noting that the connected Geth node can be a fullnode or a light client. If it is fullnode, you must enable the LES protocol. E.G. add `--light.serv 50` to the startup command line flags*. - -**Offline mode** - -```shell -checkpoint-admin sign --clef --signer --index --hash --oracle -``` - -*CHECKPOINT_HASH is obtained based on this [calculation method](https://github.com/ethereum/go-ethereum/blob/master/params/config.go#L251).* - -#### Publish - -Collect enough signatures from different trusted signers for the same checkpoint and submit them to oracle to update the "authenticated" checkpoint in the contract. - -```shell -checkpoint-admin publish --clef --rpc --signer --index --signatures -``` - -#### Status query - -Check the latest status of checkpoint oracle. - -```shell -checkpoint-admin status --rpc -``` - -### Enable checkpoint oracle in your private network - -Currently, only the Ethereum mainnet and the default supported test networks (ropsten, rinkeby, goerli) activate this feature. If you want to activate this feature in your private network, you can overwrite the relevant checkpoint oracle settings through the configuration file after deploying the oracle contract. - -* Get your node configuration file `geth dumpconfig OTHER_COMMAND_LINE_OPTIONS > config.toml` -* Edit the configuration file and add the following information - -```toml -[Eth.CheckpointOracle] -Address = CHECKPOINT_ORACLE_ADDRESS -Signers = [TRUSTED_SIGNER_1, ..., TRUSTED_SIGNER_N] -Threshold = THRESHOLD -``` - -* Start geth with the modified configuration file - -*In the private network, all fullnodes and light clients need to be started using the same checkpoint oracle settings.* \ No newline at end of file diff --git a/cmd/checkpoint-admin/common.go b/cmd/checkpoint-admin/common.go deleted file mode 100644 index 05a45dfbf..000000000 --- a/cmd/checkpoint-admin/common.go +++ /dev/null @@ -1,120 +0,0 @@ -// Copyright 2019 The go-ethereum Authors -// This file is part of go-ethereum. -// -// go-ethereum is free software: you can redistribute it and/or modify -// it under the terms of the GNU General Public License as published by -// the Free Software Foundation, either version 3 of the License, or -// (at your option) any later version. -// -// go-ethereum is distributed in the hope that it will be useful, -// but WITHOUT ANY WARRANTY; without even the implied warranty of -// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

"description": "A flaw was repoted at 2020-08-11 by John Youngseok Yang (Software Platform Lab), where a particular sequence of transactions could cause a consensus failure.\n\n- Tx 1:\n - `sender` invokes `caller`.\n - `caller` invokes `0xaa`. `0xaa` has 3 wei, does a self-destruct-to-self\n - `caller` does a `1 wei` -call to `0xaa`, who thereby has 1 wei (the code in `0xaa` still executed, since the tx is still ongoing, but doesn't redo the selfdestruct, it takes a different path if callvalue is non-zero)\n\n-Tx 2:\n - `sender` does a 5-wei call to 0xaa. No exec (since no code). \n\nIn geth, the result would be that `0xaa` had `6 wei`, whereas OE reported (correctly) `5` wei. Furthermore, in geth, if the second tx was not executed, the `0xaa` would be destructed, resulting in `0 wei`. Thus obviously wrong. \n\nIt was determined that the root cause was this [commit](https://github.com/ethereum/go-ethereum/commit/223b950944f494a5b4e0957fd9f92c48b09037ad) from [this PR](https://github.com/ethereum/go-ethereum/pull/19953).

These +// behavioural expectations allow us to design a transaction pool that is more robust +// (i.e. resending issues) and more resilient to DoS attacks (e.g. replace-flush +// attacks) than the generic tx pool. These improvements will also mean, however, +// that we enforce a significantly more aggressive strategy on entering and exiting +// the pool: +// +// - Blob transactions are large. With the initial design aiming for 128KB blobs, +// we must ensure that these only traverse the network the absolute minimum +// number of times. Broadcasting to sqrt(peers) is out of the question, rather +// these should only ever be announced and the remote side should request it if +// it wants to. +// +// - Block blob-space is limited. With blocks being capped to a few blob txs, we +// can make use of the very low expected churn rate within the pool. Notably, +// we should be able to use a persistent disk backend for the pool, solving +// the tx resend issue that plagues the generic tx pool, as long as there's no +// artificial churn (i.e. pool wars). +// +// - Purpose of blobs are layer-2s. Layer-2s are meant to use blob transactions to +// commit to their own current state, which is independent of Ethereum mainnet +// (state, txs). This means that there's no reason for blob tx cancellation or +// replacement, apart from a potential basefee / miner tip adjustment. +// +// - Replacements are expensive. Given their size, propagating a replacement +// blob transaction to an existing one should be aggressively discouraged. +// Whilst generic transactions can start at 1 Wei gas cost and require a 10% +// fee bump to replace, we suggest requiring a higher min cost (e.g. 1 gwei) +// and a more aggressive bump (100%). +// +// - Cancellation is prohibitive. Evicting an already propagated blob tx is a huge +// DoS vector. As such, a) replacement (higher-fee) blob txs mustn't invalidate +// already propagated (future) blob txs (cumulative fee); b) nonce-gapped blob +// txs are disallowed; c) the presence of blob transactions exclude non-blob +// transactions. +// +// - Malicious cancellations are possible. Although the pool might prevent txs +// that cancel blobs, blocks might contain such transaction (malicious miner +// or flashbotter). The pool should cap the total number of blob transactions +// per account as to prevent propagating too much data before cancelling it +// via a normal transaction. It should nonetheless be high enough to support +// resurrecting reorged transactions. Perhaps 4-16. +// +// - Local txs are meaningless. Mining pools historically used local transactions +// for payouts or for backdoor deals. With 1559 in place, the basefee usually +// dominates the final price, so 0 or non-0 tip doesn't change much. Blob txs +// retain the 1559 2D gas pricing (and introduce on top a dynamic blob gas fee), +// so locality is moot. With a disk backed blob pool avoiding the resend issue, +// there's also no need to save own transactions for later. +// +// - No-blob blob-txs are bad. Theoretically there's no strong reason to disallow +// blob txs containing 0 blobs. In practice, admitting such txs into the pool +// breaks the low-churn invariant as blob constraints don't apply anymore. Even +// though we could accept blocks containing such txs, a reorg would require moving +// them back into the blob pool, which can break invariants. +// +// - Dropping blobs needs delay. When normal transactions are included, they +// are immediately evicted from the pool since they are contained in the +// including block. Blobs however are not included in the execution chain, +// so a mini reorg cannot re-pool "lost" blob transactions. To support reorgs, +// blobs are retained on disk until they are finalised. +// +// - Blobs can arrive via flashbots. Blocks might contain blob transactions we +// have never seen on the network. Since we cannot recover them from blocks +// either, the engine_newPayload needs to give them to us, and we cache them +// until finality to support reorgs without tx losses. +// +// Whilst some constraints above might sound overly aggressive, the general idea is +// that the blob pool should work robustly for its intended use case and whilst +// anyone is free to use blob transactions for arbitrary non-rollup use cases, +// they should not be allowed to run amok the network. +// +// Implementation wise there are a few interesting design choices: +// +// - Adding a transaction to the pool blocks until persisted to disk. This is +// viable because TPS is low (2-4 blobs per block initially, maybe 8-16 at +// peak), so natural churn is a couple MB per block. Replacements doing O(n) +// updates are forbidden and transaction propagation is pull based (i.e. no +// pileup of pending data). +// +// - When transactions are chosen for inclusion, the primary criteria is the +// signer tip (and having a basefee/data fee high enough of course). However, +// same-tip transactions will be split by their basefee/datafee, preferring +// those that are closer to the current network limits. The idea being that +// very relaxed ones can be included even if the fees go up, when the closer +// ones could already be invalid. +// +// When the pool eventually reaches saturation, some old transactions - that may +// never execute - will need to be evicted in favor of newer ones. The eviction +// strategy is quite complex: +// +// - Exceeding capacity evicts the highest-nonce of the account with the lowest +// paying blob transaction anywhere in the pooled nonce-sequence, as that tx +// would be executed the furthest in the future and is thus blocking anything +// after it. The smallest is deliberately not evicted to avoid a nonce-gap. +// +// - Analogously, if the pool is full, the consideration price of a new tx for +// evicting an old one is the smallest price in the entire nonce-sequence of +// the account. This avoids malicious users DoSing the pool with seemingly +// high paying transactions hidden behind a low-paying blocked one. +// +// - Since blob transactions have 3 price parameters: execution tip, execution +// fee cap and data fee cap, there's no singular parameter to create a total +// price ordering on. What's more, since the base fee and blob fee can move +// independently of one another, there's no pre-defined way to combine them +// into a stable order either. This leads to a multi-dimensional problem to +// solve after every block. +// +// - The first observation is that comparing 1559 base fees or 4844 blob fees +// needs to happen in the context of their dynamism. Since these fees jump +// up or down in ~1.125 multipliers (at max) across blocks, comparing fees +// in two transactions should be based on log1.125(fee) to eliminate noise. +// +// - The second observation is that the basefee and blobfee move independently, +// so there's no way to split mixed txs on their own (A has higher base fee, +// B has higher blob fee). Rather than look at the absolute fees, the useful +// metric is the max time it can take to exceed the transaction's fee caps. +// Specifically, we're interested in the number of jumps needed to go from +// the current fee to the transaction's cap: +// +// jumps = log1.125(txfee) - log1.125(basefee) +// +// - The third observation is that the base fee tends to hover around rather +// than swing wildly. The number of jumps needed from the current fee starts +// to get less relevant the higher it is. To remove the noise here too, the +// pool will use log(jumps) as the delta for comparing transactions. +// +// delta = sign(jumps) * log(abs(jumps)) +// +// - To establish a total order, we need to reduce the dimensionality of the +// two base fees (log jumps) to a single value. The interesting aspect from +// the pool's perspective is how fast will a tx get executable (fees going +// down, crossing the smaller negative jump counter) or non-executable (fees +// going up, crossing the smaller positive jump counter). As such, the pool +// cares only about the min of the two delta values for eviction priority. +// +// priority = min(delta-basefee, delta-blobfee) +// +// - The above very aggressive dimensionality and noise reduction should result +// in transaction being grouped into a small number of buckets, the further +// the fees the larger the buckets. This is good because it allows us to use +// the miner tip meaningfully as a splitter. +// +// - For the scenario where the pool does not contain non-executable blob txs +// anymore, it does not make sense to grant a later eviction priority to txs +// with high fee caps since it could enable pool wars. As such, any positive +// priority will be grouped together. +// +// priority = min(delta-basefee, delta-blobfee, 0) +// +// Optimisation tradeoffs: +// +// - Eviction relies on 3 fee minimums per account (exec tip, exec cap and blob +// cap). Maintaining these values across all transactions from the account is +// problematic as each transaction replacement or inclusion would require a +// rescan of all other transactions to recalculate the minimum. Instead, the +// pool maintains a rolling minimum across the nonce range.

This coincided with a geth-meetup in Berlin, so the geth team could fairly quickly analyse the issue. + +He submitted a proof of concept which called the `dataCopy` precompile, where the input slice and output slice were overlapping but shifted. Doing a `copy` where the `src` and `dest` overlaps is not a problem in itself, however, the `returnData`slice was _also_ using the same memory as a backing-array. + +#### Technical details + +During CALL-variants, `geth` does not copy the input. This was changed at one point, to avoid a DoS attack reported by Hubert Ritzdorf, to avoid copying data a lot on repeated `CALL`s -- essentially combating a DoS via `malloc`. Further, the datacopy precompile also does not copy the data, but just returns the same slice. This is fine so far. + +After the execution of `dataCopy`, we copy the `ret` into the designated memory area, and this is what causes a problem. Because we're copying a slice of memory over a slice of memory, and this operation modifies (shifts) the data in the source -- the `ret`. So this means we wind up with corrupted returndata. + + +``` +1. Calling datacopy + + memory: [0, 1, 2, 3, 4] + in (mem[0:4]) : [0,1,2,3] + out (mem[1:5]): [1,2,3,4] + +2. dataCopy returns + + returndata (==in, mem[0:4]): [0,1,2,3] + +3. Copy in -> out + + => memory: [0,0,1,2,3] + => returndata: [0,0,1,2] +``` + + +#### Summary + +A memory-corruption bug within the EVM can cause a consensus error, where vulnerable nodes obtain a different `stateRoot` when processing a maliciously crafted transaction. This, in turn, would lead to the chain being split: mainnet splitting in two forks. + +#### Handling + +On the evening of 17th, we discussed options on how to handle it. We made a state test to reproduce the issue, and verified that neither `openethereum`, `nethermind` nor `besu` were affected by the same vulnerability, and started a full-sync with a patched version of `geth`. + +It was decided that in this specific instance, it would be possible to make a public announcement and a patch release: + +- The fix can be made pretty 'generically', e.g. always copying data on input to precompiles. +- The flaw is pretty difficult to find, given a generic fix in the call. The attacker needs to figure out that it concerns the precompiles, specifically the datcopy, and that it concerns the `RETURNDATA` buffer rather than the regular memory, and lastly the special circumstances to trigger it (overlapping but shifted input/output). + +Since we had merged the removal of `ETH65`, if the entire network were to upgrade, then nodes which have not yet implemented `ETH66` would be cut off from the network. After further discussions, we decided to: + +- Announce an upcoming security release on Tuesday (August 24th), via Twitter and official channels, plus reach out to downstream projects. +- Temporarily revert the `ETH65`-removal. +- Place the fix into the PR optimizing the jumpdest analysis [233381](https://github.com/ethereum/go-ethereum/pull/23381). +- After 4-8 weeks, release details about the vulnerability. + + +## Exploit + +At block [13107518](https://etherscan.io/block/13107518), mined at Aug-27-2021 12:50:07 PM +UTC, a minority chain split occurred. The discord user @AlexSSD7 notified the allcoredevs-channel on the Eth R&D discord, on Aug 27 13:09 UTC. + + +At 14:09 UTC, it was confirmed that the transaction `0x1cb6fb36633d270edefc04d048145b4298e67b8aa82a9e5ec4aa1435dd770ce4` had triggered the bug, leading to a minority-split of the chain. The term 'minority split' means that the majority of miners continued to mine on the correct chain. + +At 14:17 UTC, @mhswende tweeted out about the issue [2]. + +The attack was sent from an account funded from Tornado cash. + +It was also found that the same attack had been carried out on the BSC chain at roughly the same time -- at a block mined [12 minutes earlier](https://bscscan.com/tx/0xf667f820631f6adbd04a4c92274374034a3e41fa9057dc42cb4e787535136dce), at Aug-27-2021 12:38:30 PM +UTC. + +The blocks on the 'bad' chain were investigated, and Tim Beiko reached out to those mining operators on the minority chain who could be identified via block extradata. + + +## Lessons learned + + +### Disclosure decision + +The geth-team have an official policy regarding [vulnerability disclosure](https://geth.ethereum.org/docs/developers/geth-developer/disclosures). + +> The primary goal for the Geth team is the health of the Ethereum network as a whole, and the decision whether or not to publish details about a serious vulnerability boils down to minimizing the risk and/or impact of discovery and exploitation. + +In this case, it was decided that public pre-announce + patch would likely lead to sufficient update-window for a critical mass of nodes/miners to upgrade in time before it could be exploited.
