Takes about 10 ms, which takes pretty much all of the get_info RPC, which is called pretty often from wallets. Also add a new lock so we don't need to lock the blockchain lock, which will avoid blocking for a long time when calling the getinfo RPC while syncing. Users of get_difficulty_for_next_block who need the lock will have locked it already.

2018-03-14keypair::generate: always require hw::device to avoid possible mistakestoffu1-1/+1
2018-03-14device: untangle cyclic depenencystoffu1-10/+9
When #3303 was merged, a cyclic dependency chain was generated: libdevice <- libcncrypto <- libringct <- libdevice This was because libdevice needs access to a set of basic crypto operations implemented in libringct such as scalarmultBase(), while libringct also needs access to abstracted crypto operations implemented in libdevice such as ecdhEncode(). To untangle this cyclic dependency chain, this patch splits libringct into libringct_basic and libringct, where the basic crypto ops previously in libringct are moved into libringct_basic. The cyclic dependency is now resolved thanks to this separation: libcncrypto <- libringct_basic <- libdevice <- libcryptonote_basic <- libringct This eliminates the need for crypto_device.cpp and rctOps_device.cpp. Also, many abstracted interfaces of hw::device such as encrypt_payment_id() and get_subaddress_secret_key() were previously implemented in libcryptonote_basic (cryptonote_format_utils.cpp) and were then called from hw::core::device_default, which is odd because libdevice is supposed to be independent of libcryptonote_basic. Therefore, those functions were moved to device_default.cpp.

Both was set to 00...00.

* src/cryptnote_config.h: The constant `config::testnet::GENESIS_TX` was changed to be the same as `config::GENESIS_TX` (the mainnet's transaction) because the mainnet's transaction was being used for both networks. * src/cryptonote_core/cryptonote_tx_utils.cpp: The `generate_genesis_block` function was ignoring the `genesis_tx` parameter, and instead it was using the `config::GENESIS_TX` constant. That's why the testnet genesis transaction was changed. Also five lines of unused code were removed. Signed-off-by: Jean Pierre Dudey <jeandudey@hotmail.com>
2018-03-04Code modifications to integrate Ledger HW device into monero-wallet-cli.cslashm2-16/+24
The basic approach it to delegate all sensitive data (master key, secret ephemeral key, key derivation, ....) and related operations to the device. As device has low memory, it does not keep itself the values (except for view/spend keys) but once computed there are encrypted (with AES are equivalent) and return back to monero-wallet-cli. When they need to be manipulated by the device, they are decrypted on receive. Moreover, using the client for storing the value in encrypted form limits the modification in the client code. Those values are transfered from one C-structure to another one as previously. The code modification has been done with the wishes to be open to any other hardware wallet. To achieve that a C++ class hw::Device has been introduced. Two initial implementations are provided: the "default", which remaps all calls to initial Monero code, and the "Ledger", which delegates all calls to Ledger device.

It would fail to send, thinking it needs a destination address, since the destination matches the change address in this case.
2018-02-23blockchain: fix random sync failuresmoneromooo-monero1-1/+4
When a block is added as part of a chunk (when syncing historical blocks), a block may end up already in the blockchain if it was added to the queue before being added to the chain (though it's not clear how that could happen, but it's an implementation detail) and thus may not be added to the chain when add_block is called. This would cause m_blocks_txs_check to not be cleared, causing it to get out of sync at next call, and thus wrongfully reject the next block.

Scheme by luigi1111: Multisig for RingCT on Monero 2 of 2 User A (coordinator): Spendkey b,B Viewkey a,A (shared) User B: Spendkey c,C Viewkey a,A (shared) Public Address: C+B, A Both have their own watch only wallet via C+B, a A will coordinate spending process (though B could easily as well, coordinator is more needed for more participants) A and B watch for incoming outputs B creates "half" key images for discovered output D: I2_D = (Hs(aR)+c) * Hp(D) B also creates 1.5 random keypairs (one scalar and 2 pubkeys; one on base G and one on base Hp(D)) for each output, storing the scalar(k) (linked to D), and sending the pubkeys with I2_D. A also creates "half" key images: I1_D = (Hs(aR)+b) * Hp(D) Then I_D = I1_D + I2_D Having I_D allows A to check spent status of course, but more importantly allows A to actually build a transaction prefix (and thus transaction). A builds the transaction until most of the way through MLSAG_Gen, adding the 2 pubkeys (per input) provided with I2_D to his own generated ones where they are needed (secret row L, R). At this point, A has a mostly completed transaction (but with an invalid/incomplete signature). A sends over the tx and includes r, which allows B (with the recipient's address) to verify the destination and amount (by reconstructing the stealth address and decoding ecdhInfo). B then finishes the signature by computing ss[secret_index][0] = ss[secret_index][0] + k - cc[secret_index]*c (secret indices need to be passed as well). B can then broadcast the tx, or send it back to A for broadcasting. Once B has completed the signing (and verified the tx to be valid), he can add the full I_D to his cache, allowing him to verify spent status as well. NOTE: A and B *must* present key A and B to each other with a valid signature proving they know a and b respectively. Otherwise, trickery like the following becomes possible: A creates viewkey a,A, spendkey b,B, and sends a,A,B to B. B creates a fake key C = zG - B. B sends C back to A. The combined spendkey C+B then equals zG, allowing B to spend funds at any time! The signature fixes this, because B does not know a c corresponding to C (and thus can't produce a signature). 2 of 3 User A (coordinator) Shared viewkey a,A "spendkey" j,J User B "spendkey" k,K User C "spendkey" m,M A collects K and M from B and C B collects J and M from A and C C collects J and K from A and B A computes N = nG, n = Hs(jK) A computes O = oG, o = Hs(jM) B anc C compute P = pG, p = Hs(kM) || Hs(mK) B and C can also compute N and O respectively if they wish to be able to coordinate Address: N+O+P, A The rest follows as above. The coordinator possesses 2 of 3 needed keys; he can get the other needed part of the signature/key images from either of the other two. Alternatively, if secure communication exists between parties: A gives j to B B gives k to C C gives m to A Address: J+K+M, A 3 of 3 Identical to 2 of 2, except the coordinator must collect the key images from both of the others. The transaction must also be passed an additional hop: A -> B -> C (or A -> C -> B), who can then broadcast it or send it back to A. N-1 of N Generally the same as 2 of 3, except participants need to be arranged in a ring to pass their keys around (using either the secure or insecure method). For example (ignoring viewkey so letters line up): [4 of 5] User: spendkey A: a B: b C: c D: d E: e a -> B, b -> C, c -> D, d -> E, e -> A Order of signing does not matter, it just must reach n-1 users. A "remaining keys" list must be passed around with the transaction so the signers know if they should use 1 or both keys. Collecting key image parts becomes a little messy, but basically every wallet sends over both of their parts with a tag for each. Thia way the coordinating wallet can keep track of which images have been added and which wallet they come from. Reasoning: 1. The key images must be added only once (coordinator will get key images for key a from both A and B, he must add only one to get the proper key actual key image) 2. The coordinator must keep track of which helper pubkeys came from which wallet (discussed in 2 of 2 section). The coordinator must choose only one set to use, then include his choice in the "remaining keys" list so the other wallets know which of their keys to use. You can generalize it further to N-2 of N or even M of N, but I'm not sure there's legitimate demand to justify the complexity. It might also be straightforward enough to support with minimal changes from N-1 format. You basically just give each user additional keys for each additional "-1" you desire. N-2 would be 3 keys per user, N-3 4 keys, etc. The process is somewhat cumbersome: To create a N/N multisig wallet: - each participant creates a normal wallet - each participant runs "prepare_multisig", and sends the resulting string to every other participant - each participant runs "make_multisig N A B C D...", with N being the threshold and A B C D... being the strings received from other participants (the threshold must currently equal N) As txes are received, participants' wallets will need to synchronize so that those new outputs may be spent: - each participant runs "export_multisig FILENAME", and sends the FILENAME file to every other participant - each participant runs "import_multisig A B C D...", with A B C D... being the filenames received from other participants Then, a transaction may be initiated: - one of the participants runs "transfer ADDRESS AMOUNT" - this partly signed transaction will be written to the "multisig_monero_tx" file - the initiator sends this file to another participant - that other participant runs "sign_multisig multisig_monero_tx" - the resulting transaction is written to the "multisig_monero_tx" file again - if the threshold was not reached, the file must be sent to another participant, until enough have signed - the last participant to sign runs "submit_multisig multisig_monero_tx" to relay the transaction to the Monero network

2017-11-08Protect node privacy by proper filtering in restricted-mode RPC answersbinaryFate6-46/+80
This patch allows to filter out sensitive information for queries that rely on the pool state, when running in restricted mode. This filtering is only applied to data sent back to RPC queries. Results of inline commands typed locally in the daemon are not affected. In practice, when running with `--restricted-rpc`: * get_transaction_pool will list relayed transactions with the fields "last relayed time" and "received time" set to zero. * get_transaction_pool will not list transaction that have do_not_relay set to true, and will not list key images that are used only for such transactions * get_transaction_pool_hashes.bin will not list such transaction * get_transaction_pool_stats will not count such transactions in any of the aggregated values that are computed The implementation does not make filtering the default, so developers should be mindful of this if they add new RPC functionality. Fixes #2590.
2017-11-06track double spending in the txpoolmoneromooo-monero3-8/+62
Transactions in the txpool are marked when another transaction is seen double spending one or more of its inputs. This is then exposed wherever appropriate. Note that being marked with this "double spend seen" flag does NOT mean this transaction IS a double spend and will never be mined: it just means that the network has seen at least another transaction spending at least one of the same inputs, so care should be taken to wait for a few confirmations before acting upon that transaction (ie, mostly of use for merchants wanting to accept unconfirmed transactions).
