cryptonote: add a set_null for transaction_prefix
Since it's all inline, I suspect the compiler will merge the
duplicate stores anyway.

Avoid unnecessary temp block and copy ctor
block already has a default ctor, and the extra object
churn due to its innards (vectors, etc) is pointless.

cryptonote: sort tx_extra fields
This removes some small amount of fingerprinting entropy.
There is no consensus rule to require this since this field
is technically free form, and a transaction is free to have
custom data in it.

hw_device: support for multiple devices added [for review]
- device name is a new wallet property
- full device name is now a bit more structured so we can address particular device vendor + device path. Example: 'Ledger', 'Trezor:udp', 'Trezor:udp:127.0.0.1:21324', 'Trezor:bridge:usb01'. The part before ':' identifies HW device implementation, the optional part after ':' is device path to look for.
- new --hw-device parameter added to the wallet, can name the hardware device
- device reconnect added

store secret keys encrypted where possible
The secret spend key is kept encrypted in memory, and
decrypted on the fly when needed.

Both spend and view secret keys are kept encrypted in a JSON
field in the keys file. This avoids leaving the keys in
memory due to being manipulated by the JSON I/O API.

device: untangle cyclic depenency
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.

Cédric 73dd883d51 Ledger HW Bug fixes
Fix the way the REAL mode is handle:
  Let create_transactions_2 and create_transactions_from construct the vector of transactions.
  Then iterate on it and resign.
  We just need to add 'outs' list in the TX struct for that.

Fix default secret keys value when DEBUG_HWDEVICE mode is off
  The magic value (00...00 for view key and FF..FF for spend key) was not correctly set
  when DEBUG_HWDEVICE was off. Both was set to 00...00.

Add sub-address info in ABP map in order to correctly display destination sub-address on device

Fix DEBUG_HWDEVICE mode:
   - Fix compilation errors.
   - Fix control device init in ledger device.
   - Add more log.

cslashm e745c1e38d Code modifications to integrate Ledger HW device into monero-wallet-cli.
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.

Add N/N multisig tx generation and signing
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

Dion Ahmetaj 69ab14d91e More robust battery status handling.
Added an extra path to check for linux power supply status.
Added ignore battery option. If set to true, then when we can't figure out
the power status, we'll assume the system is plugged in.

Dion Ahmetaj a493c0b196 BACKGROUND_MINING_MINER_MONITOR_INVERVAL_IN_SECONDS was odr-used, so required a definition.
Instead of adding a declaration to cpp file, I changed it to non odr-used.

Dion Ahmetaj ad95e65028 Added a note about smart mining to status command. Fixed up a bug where I was resetting bg mining enabled instead of started. Upped the miner threshold. Also moved setting of enabled on start above miner thread creation since starting with true, then stopping, then starting with false resulted in race condition. 2017-02-10 18:07:43 -05:00

Dion Ahmetaj 68652cd94d Added some //TODO comments pertaining to returning enums instead of bools in order to be better able to handle failure states. 2017-02-10 18:07:41 -05:00
Dion Ahmetaj 0b1045ed7d Moved around checking of AC power in order to bail quicker to sleep if not plugged in. 2017-02-10 18:07:40 -05:00
Dion Ahmetaj 2937fdbbbf Moved setting of previous process times to block where background mining is started, and added an explicit sleep in that block to wait for some mining to occur. 2017-02-10 18:07:40 -05:00
Dion Ahmetaj 21a1e0252f Set background mining started bool to false on bg thread start. If mining::stop then mining::start, idle logic is re-run instead of starting immediately (if it was running before stop). 2017-02-10 18:07:39 -05:00
Dion Ahmetaj 345ed4823c Background/smart mining. If a users' computer is plugged into a power
source, and CPU has been idle for some time, then begin mining to some
threshold (don't destroy the users' CPU).

This patch only supports windows and linux (I've only tested on Win64 and
Ubuntu).

The variables currently default to pretty conservative values (i.e. 20%
CPU mining threshold).
