2013-09-28Inline signature serializerPieter Wuille
Instead of building a full copy of a CTransaction being signed, and then modifying bits and pieces until its fits the form necessary for computing the signature hash, use a wrapper serializer that only serializes the necessary bits on-the-fly. This makes it easier to see which data is actually being hash, reduces load on the heap, and also marginally improves performances (around 3-4us/sigcheck here). The performance improvements are much larger for large transactions, though. The old implementation of SignatureHash is moved to a unit tests, to test whether the old and new algorithm result in the same value for randomly-constructed transactions.

2013-09-18autotools: fix the Makefile.include to be safely included anywhere.Cory Fields
This way we can reuse rules rather than duplicating them.
2013-09-16included-tests: generate binary data from test files for inclusion into test ↵Cory Fields
binaries This change moves test data into the binaries rather than reading them from the disk at runtime. Advantages: - Tests become distributable - Cross-compile friendly. Build on one machine and execute in an arbitrary location on another. - Easier testing for backports. Users can verify that tests pass without having to track down corresponding test data. - More trustworthy test results and easier quality assurance as tests make fewer assumptions about their environment. - Tests could theoretically run at client/daemon startup and exit on failure. Disadvantages: - Required 'hexdump' build-dependency. This is a standard bsd tool that should be usable everywhere. It is likely already installed on all build-machines. - Tests can no longer be fudged after build by altering test-data.

2013-08-25Document and test OP_RESERVED weirdnessPeter Todd
Seems it was forgotten about when IsPushOnly() and the unittests were written. A particular oddity is that OP_RESERVED doesn't count towards the >201 opcode limit unlike every other named opcode.

rather than a key. CreateNewBlockWithKey() helper is added to restore existing functionality, making this an equivalent-transformation change.

BIP 32 derivation + test vectors
2013-08-16Only create signatures with even S, and verification mode to check.Pieter Wuille
To fix a minor malleability found by Sergio Lerner (reported here: https://bitcointalk.org/index.php?topic=8392.msg1245898#msg1245898) The problem is that if (R,S) is a valid ECDSA signature for a given message and public key, (R,-S) is also valid. Modulo N (the order of the secp256k1 curve), this means that both (R,S) and (R,N-S) are valid. Given that N is odd, S and N-S have a different lowest bit. We solve the problem by forcing signatures to have an even S value, excluding one of the alternatives. This commit just changes the signing code to always produce even S values, and adds a verification mode to check it. This code is not enabled anywhere yet. Existing tests in key_tests.cpp verify that the produced signatures are still valid.
2013-08-09Reject non-canonically-encoded sizesGavin Andresen
The length of vectors, maps, sets, etc are serialized using Write/ReadCompactSize -- which, unfortunately, do not use a unique encoding. So deserializing and then re-serializing a transaction (for example) can give you different bits than you started with. That doesn't cause any problems that we are aware of, but it is exactly the type of subtle mismatch that can lead to exploits. With this pull, reading a non-canonical CompactSize throws an exception, which means nodes will ignore 'tx' or 'block' or other messages that are not properly encoded. Please check my logic... but this change is safe with respect to causing a network split. Old clients that receive non-canonically-encoded transactions or blocks deserialize them into CTransaction/CBlock structures in memory, and then re-serialize them before relaying them to peers. And please check my logic with respect to causing a blockchain split: there are no CompactSize fields in the block header, so the block hash is always canonical. The merkle root in the block header is computed on a vector<CTransaction>, so any non-canonical encoding of the transactions in 'tx' or 'block' messages is erased as they are read into memory by old clients, and does not affect the block hash. And, as noted above, old clients re-serialize (with canonical encoding) 'tx' and 'block' messages before relaying to peers.
2013-08-08Make RPC password resistant to timing attacksGavin Andresen
Fixes issue#2838; this is a tweaked version of pull#2845 that should not leak the length of the password and is more generic, in case we run into other situations where we need timing-attack-resistant comparisons.

2013-08-02Simplify storage of orphan transactionsGavin Andresen
Orphan transactions were stored as a CDataStream pointer; this changes the mapOrphanTransactions data structures to store orphans as a CTransaction. This also fixes CVE-2013-4627 by always re-serializing transactions before relaying them.

2013-06-19Introduce a CChainParameters singleton class and regtest mode.Mike Hearn
The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.
2013-06-05Removed AcceptToMemoryPool method from CTransaction. This method belongs to ↵Eric Lombrozo
the mempool instance. Removed AreInputsStandard from CTransaction, made it a regular function in main. Moved CTransaction::GetOutputFor to CCoinsViewCache. Moved GetLegacySigOpCount and GetP2SHSigOpCount out of CTransaction into regular functions in main. Moved GetValueIn and HaveInputs from CTransaction into CCoinsViewCache. Moved AllowFree, ClientCheckInputs, CheckInputs, UpdateCoins, and CheckTransaction out of CTransaction and into main. Moved IsStandard and IsFinal out of CTransaction and put them in main as IsStandardTx and IsFinalTx. Moved GetValueOut out of CTransaction into main. Moved CTxIn, CTxOut, and CTransaction into core. Added minimum fee parameter to CTxOut::IsDust() temporarily until CTransaction is moved to core.h so that CTxOut needn't know about CTransaction.
