When RingCT is enabled, outputs from coinbase transactions
are created as a single output, and stored as RingCT output,
with a fake mask. Their amount is not hidden on the blockchain
itself, but they are then able to be used as fake inputs in
a RingCT ring. Since the output amounts are hidden, their
"dustiness" is not an obstacle anymore to mixing, and this
makes the coinbase transactions a lot smaller, as well as
helping the TXO set to grow more slowly.
Also add a new "Null" type of rct signature, which decreases
the size required when no signatures are to be stored, as
in a coinbase tx.
|
|
and remove some unnecessary variables in the checking code
|
|
|
|
This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.
|
|
Nothing is pruned, but this allows easier changes later.
|
|
The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.
Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.
|
|
for future expansion
|
|
This element is used in the generation of the MLSAG, but isn't
needed in verification.
Also misc changes in the cryptonote code to match, by mooo.
|
|
Saves some substantial space.
Also avoid calculating tx hashes we don't need.
|
|
|
|
Makes it easier to track what is going on.
|
|
This ensures we get rct transactions when appropriate

Print number of confirmations if the tx is in the blockchain,

Scheme design from luigi1114.
|
|
They can be reconstructed from vout
|
|
|
|
|
|
This plugs a privacy leak, where the wallet tells the daemon
which transactions contain outputs for the wallet by asking
for additional information for that particular transaction.
As a nice bonus, this actually makes refresh slightly faster.
|
|
|
|
|
|
We try to avoid related inputs, when possible
|
|
Found by luigi1111w
|
|
With RCT, we allow 0 size outputs, to try and encourage txes
with two inputs and two outputs. Consolidation would then
have two non zero inputs, one zero output, and one larger
output.
|
|
|
|
|
|
|
|
|
|
|
|
Allows the fake outs to be in different positions for each ring.
For rct inputs only.
|
|
Before the normal selection, we attempt to find either one or two
suitable outputs to use as inputs to the rct tx. The intent is that
most rct txes will have one or two inputs, and we want all to look
the same if possible.
When two outputs are needed, we try to find a pair which are not
related (ie, by being from the same or similar block height).
|
|
|
|
|
|
The "transfer" simplewallet command is renamed to "transfer_original".
"transfer_new" is renamed "transfer", "transfer_rct" is removed,
and the new "transfer" now selects rct or non rct transactions
based on the current block height.
|
|
|
|
Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.
This code relies on two things:
- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).
- the commitment must be directly after the rest of the data
in outkey and output_data_t.
|
|
to protect the non-signatures parts of the tx from tampering.
|
|
|
|
The mixRing (output keys and commitments) and II fields (key images)
can be reconstructed from vin data.
This saves some modest amount of space in the tx.
|
|
|
|
rather than using the current one. No functional changes, but may
save some bugs in the future.
|
|
|
|
If the blockchain gets reorganized, all outputs spent in the part
of the blockchain that's blown away need to be reset to unspent
(they may end up spent again on the blocks that replace the blocks
that are removed, however).
|
|
|
|
ie, more data or less data than expected in various fields
|
|
|
|
|
|
It is not yet constrained to a fork, so don't use on the real network
or you'll be orphaned or rejected.
|
|
- we need to drop the new m_tx_indices database
- we reset the version to current version
This fixes the core tests failing to initialize.
|
|
One to commit to an amount with zero key (for use with fake
commitments for pre-rct outputs), and one with an arbitrary
key (for rct outputs).
|
|
It may be suboptimal, but it's a pain to have to rebuild everything
when some of this changes.
Also, no clue why there seems to be two different code paths for
serializing a tx...
|
|
|
|
|
|
|
|
|
|
A new version of genRct takes the mixRing as parameter, instead
of the inPk. inPk are part of the mixRing, and it is cleaner to
pass the mixRing data than to fetch it from the RingCT code.
A new version of decodeRct also returns the mask.
Also, failure to decode throws, so errors are properly detected.

Plug rpage leak in cursor_set
|
|
This plugs a privacy leak from the wallet to the daemon,
as the daemon could previously see what input is included
as a transaction input, which the daemon hadn't previously
supplied. Now, the wallet requests a particular set of
outputs, including the real one.
This can result in transactions that can't be accepted if
the wallet happens to select too many outputs with non standard
unlock times. The daemon could know this and select another
output, but the wallet is blind to it. It's currently very
unlikely since I don't think anything uses non default
unlock times. The wallet requests more outputs than necessary
so it can use spares if any of the returns outputs are still
locked. If there are not enough spares to reach the desired
mixin, the transaction will fail.

|
|
This db is now dropped unconditionally, so may or may not be there
in the first place.
|
|
|
|
Simplewallet improperly skipped the restore from height code if
restoring a deterministic wallet AND not specifying a wallet file in the
command line. The other generate options require a wallet file as an
argument, which prevents "ask_wallet_create_if_needed()" from being
called, which in turn causes "m_generate_new" to remain unset.
Specifying a wallet file at launch with --restore-deterministic emulated
this behavior.
|
|
|
|
|
|
Also, minor cleanup of redundant flag-setting code.
|
|
This constrains the number of instances of any amount
to the unlocked ones (as defined by the default unlock time
setting: outputs with non default unlock time are not
considered, so may be counted as unlocked even if they are
not actually unlocked).

The previous logic that used a COMMON_*_FLAGS intermediate variable

3c92c2f cmake: do not install hook on throw when building tests (redfish)
|
|
This is an attempt to fix build with STATIC=ON on OSX (#932):
[ 95%] Linking CXX executable ../../bin/bitmonerod Undefined symbols for
architecture x86_64: "___real___cxa_throw", referenced from:
___wrap___cxa_throw in libcommon.a(stack_trace.cpp.o) ld: symbol(s) not found
for architecture x86_64
|
|
This fixes build of tests with STATIC=ON, which failed with:
/tmp/cc8lNtqY.ltrans12.ltrans.o: In function
`boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::thread_resource_error>
>::rethrow() const [clone .lto_priv.41]':
cc8lNtqY.ltrans12.o:(.text+0x4e): undefined reference to `__wrap___cxa_throw'
The hook is implemented in libcommon, which is not linked into some of the test
binaries. An alternative solution is to link all tests against libcommon,
but that seems worse because it introduces a false dependency (also,
I tried that and for some of the test binaries the linker still failed to
pick up the symol from libcommon, strangely.)
|
|
This code should die anyway.

8bed9a4 cmake: wallet: libunbound is not always static (redfish)
|
|
They are used to export a signed set of key images from a wallet
with a private spend key, so an auditor with the matching view key
may see which of those are spent, and which are not.
|
|
It is not clear why libunbound was added to this in the first place,
since it wasn't here before and #915 doesn't seem to introduce any
new dependency on it.
Tested build with STATIC=OFF (with and without libunbound-dev libunbound8
installed) and STATIC=ON, on Ubuntu Trusty, Debian Jessie, and Arch
Linux. For static builds, beware of #926 and #907.
If this hack was introduced to make it build on some other system
(Windows? OS X?), then it will have to be dealt with, but not this way.

61ed40a Tests: fix signed/unsigned comparison in hash-target (anonimal)
|
|
The tests currently issue a warning that
"warning: -fassociative-math disabled; other options take precedence"
The associative math optimization is turned on indirectly by -Ofast.
Apparently, the optimization is forced to be disabled, while compiling
test harnesses generated by Google Test framework.
Unfortunately, there is no -Wno-error=* flag to disable this warning
(see gcc --help=warnings).
An alternative to this patch is to disable the optimization explicitly
with -fno-associative-math, but that seems worse.
Another alternative is to not pass -Ofast for tests build, but we
want the tests to be built with exact same optimization flags as
the code being tested, otherwise the value of the tests is diminished.
Another alternative is to remove -Werror from the entire build, but
it's good to include that flag to preclude people leaving warnings.
A note regarding implementation of not passing -Werror for tests:
I considered filtering out -Werror from CMAKE_{C,CXX}_FLAGS but
that seems to be worse because it's surprizing behavior, to those
reading the code that adds -Werror. It is better to add it for
when it is used and not added otherwise. I also considered relying
on order, adding -Werror after inluding 'tests' subdir, but before
including the other subdirs, but that also seems cryptic to the
reader. So, I settled with the current solution, of explicitly
setting CMAKE_{C,CXX}_FLAGS to different values before including the
respective subdir.
Testing done: compared compiler invocation for non-tests source files
using `make VERBOSE=1` with and without this commit: the only difference
is the position of -Werror. So, this commit doesn't change the binary.
