Contains two modifications to improve ASIC resistance: shuffle and integer math.
Shuffle makes use of the whole 64-byte cache line instead of 16 bytes only, making Cryptonight 4 times more demanding for memory bandwidth.
Integer math adds 64:32 bit integer division followed by 64 bit integer square root, adding large and unavoidable computational latency to the main loop.

This class will allow mlocking small objects, of which there
may be several per page. It adds refcounting so pages are only
munlocked when the last object on that page munlocks.
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.
63e342b crypto: move null_pkey/null_skey to the cpp file (moneromooo-monero)
0496c7c crypto: do not use boost::value_initialized to init null skey/pkey (moneromooo-monero)
Fixes failing test during Arch package build (due to attempt to write to
~/.bitmonero/...).
Prefix temp dir path with "monero-" because we are not putting it on the
system, so good to identify ourselves in case the dir gets left over due
to crash, etc.
149da42 db_lmdb: enable batch transactions by default (stoffu)
34cb6b4 add --regtest and --fixed-difficulty for regression testing (vicsn)
9e1403e update get_info RPC and bump RPC version (vicsn)
207b66e first new functional tests (vicsn)
This gets rid of the temporary precalc cache.
Also make the RPC able to send data back in binary or JSON,
since there can be a lot of data
This bumps the LMDB database format to v3, with migration.
on_generateblocks RPC call combines functionality from the on_getblocktemplate and on_submitblock RPC calls to allow rapid block creation. Difficulty is set permanently to 1 for regtest.
Makes use of FAKECHAIN network type, but takes hard fork heights from mainchain
Default reserve_size in generate_blocks RPC call is now 1. If it is 0, the following error occurs 'Failed to calculate offset for'.
Queries hard fork heights info of other network types
f8dd433 epee: fix detection of 172.16.0.0/172.31.255.255 local IP range (moneromooo-monero)
5db9e3c unit_tests: add tests for local IP range detection (moneromooo-monero)
db55263 threadpool: allow constructing an object, and misc tweaks (moneromooo-monero)
ce173cb core: remove threadpool dependency from header (moneromooo-monero)
3147468 unit_tests: add threadpool unit test (moneromooo-monero)
for privacy reasons, so an untrusted node can't easily track
wallets from IP address to IP address, etc. The granularity
is 1024 blocks, which is about a day and a half.
a connection's timeout is halved for every extra connection
from the same host.
Also keep track of when we don't need to use a connection
anymore, so we can close it and free the resource for another
connection.
Also use the longer timeout for non routable local addresses.
hash: add prehashed version cn_slow_hash_prehashed
slow-hash: let cn_slow_hash take 4th parameter for deciding prehashed or not
slow-hash: add support for prehashed version for the other 3 platforms
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.
