* core: vm: cache GPK to prevent DoS (#335)Wei-Ning Huang2019-04-091-1/+18

* core: add cache for DKG MPK and complaint (#334)Wei-Ning Huang2019-04-091-20/+21
| | | | | Since deserializing DKG related items are extremely slow (takes about 3 seconds for 100 items), we cache it in the governance interface.

* consensus: dexcon: disqualify dead node (#280)Wei-Ning Huang2019-04-093-30/+128
| | | | | | | | | | Since a qualified node might fail stopped, we need to remove them from qualified nodes to maintain network integrity. We do this by inspect the previous round to see if there are dead nodes. A dead node is a notary set node that does not propose any block in the previous round. We disqualify them by fining them so their staked value is 1 wei below minStake. This make them unqualified for being notary set in the follow on rounds.

* core: vm: create new oracle contract instance in each call (#251)Wei-Ning Huang2019-04-093-6/+16
| | | | | Since the VM might be called from different source (downloader, RPC, etc.). We need to make the call state separate. Modify the calling sequence so a new oracle contract instance is used on each run.

* core: vm: remove delegation mechanism (#245)Wei-Ning Huang2019-04-094-994/+259
| | | | | | | | | | | | | The current delegation mechanism are prone to unstaking attack. i.e. a malicious attacker could unstake a small amount from a lot of node it staked before and make them unqualified, which leads to potential failure of the network. Since DEXON does not use consensus like DPoS, node is required to have at least MinStake in order to become a node. Voting mechanism is not required in our system since qualified node does not depends on the number of votes. Instead of managing the delegation mechanism in governance contract, we should let the owner manage the delegation and reward distribution mechanism on their own.

* core: vm: validate addDKGMasterPublicKey caller properly (#220)Wei-Ning Huang2019-04-093-60/+59
| | | | | | There are two keys in the system: one is the owner's key which is used for stake / unstake. The other is the node key which is used for DKG related operations. We need to allow them to be different so fund renmains safe even if the the node key is lost.

* core: vm: more change to the randomness calculation (#175)Wei-Ning Huang2019-04-091-5/+5
| | | | To prevent attacker from sending TX through a intermediate contract. Always use the original tx sender's adddress and nonce.
* core: vm: modify randomness calculation algorithm (#173)Wei-Ning Huang2019-04-092-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | The original algorithm used for calculating algorithm is vulnerable to cross context re-entry attack. Example as follows: contract B { event Value(uint256 value); uint256 public value; function call() public { value = rand; emit Value(value); } } contract A { function randTwice(address bAddr) public { B b = B(bAddr); b.call.gas(100000)(); b.call.gas(100000)(); } } The two `b.call` will result in the same randomness value. This commit fix the issue by recording a called index used to store how many times opRand is called, and use it as argument to the Keccak call.

* core, cmd/puppeth: implement constantinople fix, disable EIP-1283 (#18486)Martin Holst Swende2019-01-302-2/+8
| | | | | | | | | | | | | | | | | This PR adds a new fork which disables EIP-1283. Internally it's called Petersburg, but the genesis/config field is ConstantinopleFix. The block numbers are: 7280000 for Constantinople on Mainnet 7280000 for ConstantinopleFix on Mainnet 4939394 for ConstantinopleFix on Ropsten 9999999 for ConstantinopleFix on Rinkeby (real number decided later) This PR also defaults to using the same ConstantinopleFix number as whatever Constantinople is set to. That is, it will default to mainnet behaviour if ConstantinopleFix is not set.This means that for private networks which have already transitioned to Constantinople, this PR will break the network unless ConstantinopleFix is explicitly set!

| | | | | Makes Interface interface a bit more stateless and abstract. Obviously this change is dictated by EVMC design. The EVMC tries to keep the responsibility for EVM features totally inside the VMs, if feasible. This makes VM "stateless" because VM does not need to pass any information between executions, all information is included in parameters of the execute function.
* core/vm, tests: update tests, enable constantinople statetests, fix SAR ↵Martin Holst Swende2018-09-041-1/+1
| | | | | | | | | | | | | | | opcode (#17538) This commit does a few things at once: - Updates the tests to contain the latest data from ethereum/tests repo. - Enables Constantinople state tests. This is needed to be able to fuzz-test the evm with constantinople rules. - Fixes the error in opSAR that we've known about for some time. I was kind of saving it to see if we hit upon it with the random test generator, but it's difficult to both enable the tests and have the bug there -- we don't want to forget about it, so maybe it's better to just fix it.

| | | | | | | | | | | | | | | | | | With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).

It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)
