2019-02-11Merge #15226: Allow creating blank (empty) wallets (alternative)MeshCollider
7687f7873 [wallet] Support creating a blank wallet (Andrew Chow) Pull request description: Alternative (kind of) to #14938 This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted. Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938. Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty". This is built on top of #15225 in order to fix GUI issues.

2019-02-10[wallet] Support creating a blank walletAndrew Chow
A blank wallet is a wallet that has no keys, script or watch only things. A new wallet flag indicating that it is blank will be set when the wallet is blank. Once it is no longer blank (a seed has been generated, keys or scripts imported, etc), the flag will be unset.

2019-02-07Merge #14897: randomize GETDATA(tx) request order and introduce bias toward ↵Pieter Wuille
outbound 1cff3d6cb0 Change in transaction pull scheduling to prevent InvBlock-related attacks (Gleb Naumenko) Pull request description: This code makes executing two particular (and potentially other) attacks harder. ### InvBlock This behavior was described well [here](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf) (page 11). Per current implementation, if node A receives _INV_ (tx) from node B, node A sends _GETDATA_ to B and waits for _TX_ message back. Node A is likely to receive more _INVs_ (regarding the same tx) from other peers. But node A would not send another _GETDATA_ unless it does not hear _TX_ back from node B for next 2 minutes (to save bandwidth) Thus, if B is a malicious node, it can prevent node A from getting the transaction (even if all A’s peers have it) for 2 minutes. This behavior seems to be an inherent limitation of the current P2P relay protocol, and I don’t see how it can be fundamentally changed (I can see workarounds which involve rewriting a lot of P2P code though). ### What does this PR fix? The attacks I’m looking at involve preventing A from learning the transaction for 2*N minutes. To do that, an attacker has to spin up N nodes and send N _INVs_ simultaneously to node A (then InvBlocks will be queued with an interval of 2 minutes according to current implementation) More precisely, 2 scenarios I’m looking at are: 1. An attacker censors a particular transaction. By performing InvBlock from different nodes, an attacker can execute a network-wide censorship of a particular transaction (or all transactions). The earlier an attacker founds the transaction he wants to censor, the easier it is to perform an attack. As it was pointed out by @gwillen, this is even more dangerous in the case of lightning, where transactions are known in advance. 2. Topology inference described in papers [1](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf), [2](https://arxiv.org/pdf/1812.00942.pdf) involve network-wide InvBlock. This fix would not mitigate this type of inference, but I believe it will make it more expensive to perform (an attacker would have to create more transactions and perform more rounds to learn the topology, the second paper itself notes that InvBlock isolation is important for the attack). ### How does it work This PR introduces bias toward outbound connections (they have higher priority when a node chooses from whom it should request a transaction) and randomizes the order. As per @gmaxwell suggestion, GETDATA requests queue is created after processing all incoming messages from all nodes. After this fix, if the incoming messages were [I1, I2, I3, O1, O2, O3, O4], the queue for _GETDATA_ may look like [O2, O1, O3, O4, I1, I3, I2, ….]. If {I1, I2, I3} were significantly earlier (but the difference is less than TX_TIMEOUT=60 s) than others, the queue for _GETDATA_ may look like [I2, O2, O1, O3, O4, I1, I3, ….]. ### Other comments: 1. This mitigation works better if the connectivity is higher (especially outbound, because it would be less likely that 2 _GETDATAs_ for inbound malicious nodes queued together) Tree-SHA512: 2ad1e80c3c7e16ff0f2d1160aa7d9a5eaae88baa88467f156b987fe2a387f767a41e11507d7f99ea02ab75e89ab93b6a278d138cb1054f1aaa2df336e9b2ca6a

While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code. `perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke. ### Example ```python with node.profile_with_perf("large-msgs"): for i in range(200): node.p2p.send_message(some_large_msg) node.p2p.sync_with_ping() ``` This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`). Running `perf report` generates nice output about where the node spent most of its time while running that part of the test: ```bash $ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \ | c++filt \ | less # To display the perf.data header info, please use --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 135 of event 'cycles:pp' # Event count (approx.): 1458205679493582 # # Children Self Command Shared Object Symbol # ........ ........ ............... ................... ........................................................................................................................................................................................................................................................................ # 70.14% 0.00% bitcoin-net bitcoind [.] CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) | ---CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) 70.14% 0.00% bitcoin-net bitcoind [.] CNetMessage::readData(char const*, unsigned int) | ---CNetMessage::readData(char const*, unsigned int) CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) 35.52% 0.00% bitcoin-net bitcoind [.] std::vector<char, zero_after_free_allocator<char> >::_M_fill_insert(__gnu_cxx::__normal_iterator<char*, std::vector<char, zero_after_free_allocator<char> > >, unsigned long, char const&) | ---std::vector<char, zero_after_free_allocator<char> >::_M_fill_insert(__gnu_cxx::__normal_iterator<char*, std::vector<char, zero_after_free_allocator<char> > >, unsigned long, char const&) CNetMessage::readData(char const*, unsigned int) CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) ... ``` Tree-SHA512: 9ac4ceaa88818d5eca00994e8e3c8ad42ae019550d6583972a0a4f7b0c4f61032e3d0c476b4ae58756bc5eb8f8015a19a7fc26c095bd588f31d49a37ed0c6b3e
