Pull request description:

  @sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.

  Includes tests from #11487.

Merge #11511: [Init] Remove redundant exit(EXIT_FAILURE) instances and replace with return false
b296bf1 Init: Remove redundant exit(EXIT_FAILURE) instances and replace with return false (donaloconnor)

Pull request description:

  While reviewing the bitcoin code I noticed that there are a few exit(EXIT_FAILURE) at various places in the AppInit function.

  This function returns to main() which will return/exit with EXIT_FAILURE so returning false instead of an explicit exit(EXIT_FAILURE) seems to be cleaner.

  This PR attempts to make things a bit more consistent.

  There is a subtle difference between exit() and return from main in that the exit() will not clean up any local vars but I don't think this makes a difference in this case. Using exit() might even lead to bugs in the future where the dtor of local objects are expected to be called.

015a5258ad Reject headers building on invalid chains by tracking invalidity
This tracks the set of all known invalid-themselves blocks (ie
blocks which we attempted to connect but which were found to be
invalid). This is used to cheaply check if new headers build on an
invalid chain.

While we're at it we also resolve an edge-case in invalidateblock
on pruned nodes which results in them needing a reindex if they
fail to reorg.

Nowhere else in the protocol do we send headers which are for
blocks we have not fully validated except in response to getheaders

such request (whether for an invalid block or not) in at least two
years of debug.log output, indicating that this should have minimal

Merge #11541: Build: Fix Automake warnings when running autogen.sh
cc5c39d [Build] Add AM_OBJCXXFLAGS and QT_PIE_FLAGS to OBJCXXFLAGS to future-proof darwin targets (fanquake)
f8c6697 Fix automake warnings when running autogen.sh (Evan Klitzke)

Pull request description:

  Adjusted @eklitzke's commit to completely remove GZIP_ENV.
  Added a commit to address OBJCXXFLAGS.
  Rebased on master.
  Relevant info from @theuni & #11013 below.

  --------
  GZIP_ENV was indeed added for determinism, but gitian exports this as needed, so it's not really necessary. I'd rather just remove it.

  The mm.o rule was added to support XCode 4.2's ancient version of automake. That's irrelevant now, so it makes sense to remove that too.

  All darwin targets are PIE by default, so we don't technically need the flags, but I'd be more comfortable if we hooked up the OBJCXXFLAGS in case future ones are added.

  --------

  The second commit addresses the last point, but could probably use a better commit message.
  These warnings are removed from autogen output:
  ```

Merge #11568: Disconnect outbound peers on invalid chains
37886d5e2 Disconnect outbound peers relaying invalid headers (Suhas Daftuar)
4637f1852 moveonly: factor out headers processing into separate function (Suhas Daftuar)

Pull request description:

  Alternate to #11446.

  Disconnect outbound (non-manual) peers that serve us block headers that are already known to be invalid, but exempt compact block announcements from such disconnects.

  We restrict disconnection to outbound peers that are using up an outbound connection slot, because we rely on those peers to give us connectivity to the honest network (our inbound peers are not chosen by us and hence could all be from an attacker/sybil).  Maintaining connectivity to peers that serve us invalid headers is sometimes desirable, eg after a soft-fork, to protect unupgraded software from being partitioned off the honest network, so we prefer to only disconnect when necessary.

  Compact block announcements are exempted from this logic to comply with BIP 152, which explicitly permits nodes to relay compact blocks before fully validating them.

Merge #11490: Disconnect from outbound peers with bad headers chains
e065249 Add unit test for outbound peer eviction (Suhas Daftuar)
5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)

Pull request description:

  The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.

  The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:

  For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip.  If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes.  If after two minutes their best known block has insufficient work, we disconnect that peer.

  We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.

  We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split.  Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect.  This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.

5a6d00c6de Permit disconnection of outbound peers on bad/slow chains
Currently we have no rotation of outbound peers.  If an outbound peer
stops serving us blocks, or is on a consensus-incompatible chain with
less work than our tip (but otherwise valid headers), then we will never
disconnect that peer, even though that peer is using one of our 8
outbound connection slots.  Because we rely on our outbound peers to
find an honest node in order to reach consensus, allowing an
incompatible peer to occupy one of those slots is undesirable,
particularly if it is possible for all such slots to be occupied by such
peers.

Protect against this by always checking to see if a peer's best known
block has less work than our tip, and if so, set a 20 minute timeout --
if the peer is still not known to have caught up to a chain with as much
work as ours after 20 minutes, then send a single getheaders message,
wait 2 more minutes, and if a better header hasn't been received by then,
disconnect that peer.

Note:

- we do not require that our peer sync to the same tip as ours, just an
equal or greater work tip.  (Doing otherwise would risk partitioning the
network in the event of a chain split, and is also unnecessary.)

- we pick 4 of our outbound peers and do not subject them to this logic,
to be more conservative. We don't wish to permit temporary network
issues (or an attacker) to excessively disrupt network topology.

BDB caches do not work properly when more than one open database has the same

Merge #11062: [mempool] Mark mempool import fails that were found in mempool as 'already there'
258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm)

Pull request description:

  I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool.

  This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'.

  Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

cb06edf938 Fix wallet RPC race by waiting for callbacks in sendrawtransaction 2017-10-13 19:30:15 -04:00
Matt Corallo
e545dedf72 Also call other wallet notify callbacks in scheduler thread
This runs Block{Connected,Disconnected}, SetBestChain, Inventory,
and TransactionAddedToMempool on the background scheduler thread.

Of those, only BlockConnected is used outside of Wallet/ZMQ, and
is used only for orphan transaction removal in net_processing,
something which does not need to be synchronous with anything
else.

This partially reverts #9583, re-enabling some of the gains from
 #7946. This does not, however, re-enable the gains achieved by
repeatedly releasing cs_main between each transaction processed.

17220d6325 Use callbacks to cache whether wallet transactions are in mempool
This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.

Thanks to @morcos for the suggestion to do this.

Note that there are several race conditions introduced here:

 * If a user calls sendrawtransaction from RPC, adding a
   transaction which is "trusted" (ie from them) and pays them
   change, it may not be immediately used by coin selection until
   the notification callbacks finish running. No such race is
   introduced in normal transaction-sending RPCs as this case is
   explicitly handled.

 * Until Block{Connected,Disconnected} and
   TransactionAddedToMempool calls also run in the CSceduler
   background thread, there is a race where
   TransactionAddedToMempool might be called after a
   Block{Connected,Disconnected} call happens.

 * Wallet will write a new best chain from the SetBestChain
   callback prior to having processed the transaction from that
   block.

[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."

44407100f Replace relevant services logic with a function suite. (Matt Corallo)

Pull request description:

  This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.

  Adds HasAllRelevantServices and GetRelevantServices, which check
  for NETWORK|WITNESS.

  This changes the following:
   * Removes nRelevantServices from CConnman, disconnecting it a bit
     more from protocol-level logic.
   * Replaces our sometimes-connect-to-!WITNESS-nodes logic with
     simply always requiring WITNESS|NETWORK for outbound non-feeler
     connections (feelers still only require NETWORK).
   * This has the added benefit of removing nServicesExpected from
     CNode - instead letting net_processing's VERSION message
     handling simply check HasAllRelevantServices.
   * This implies we believe WITNESS nodes to continue to be a
     significant majority of nodes on the network, but also because
     we cannot sync properly from !WITNESS nodes, it is strange to
     continue using our valuable outbound slots on them.
   * In order to prevent this change from preventing connection to
     -connect= nodes which have !WITNESS, -connect nodes are now
     given the "addnode" flag. This also allows outbound connections
     to !NODE_NETWORK nodes for -connect nodes (which was already true
     of addnodes).
   * Has the (somewhat unintended) consequence of changing one of the
     eviction metrics from the same
     sometimes-connect-to-!WITNESS-nodes metric to requiring
     HasRelevantServices.

  This should make NODE_NETWORK_LIMITED much simpler to implement.

Pull request description:

  This fixes "Wallet file not specified" errors when making batch wallet RPC calls with more than one wallet loaded. This issue was reported by @NicolasDorier in https://github.com/bitcoin/bitcoin/issues/11257

  Request URI is not used for anything except multiwallet request dispatching, so this change has no other effect.

Pull request description:

  Document assumptions (via `assert(…)`:s) that are being made to avoid division by zero.

  Rationale:
  * Make it clear to human reviewers and non-human static analyzers that what might look like potential division by zero cases are written the way they are intentionally (these cases are currently flagged by various static analyzers).

a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)

Pull request description:

  Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.

Pull request description:

  What started as a simple task to add test coverage ended up giving way to a light refactoring. This consolidates the mostly-identical `CMerkleBlock` constructors into one (using C++11 constructor delegation) and adds coverage for the by-txids construction case.

Merge #11284: Fix invalid memory access in CScript::operator+= (guidovranken, ajtowns)
d601f16 Fix invalid memory access in CScript::operator+= (Anthony Towns)

Pull request description:

  This is a fix for #11114 -- invoking "s += s" gets turned into "s.insert(s.end(), s.begin(), s.end())" which can result in an invalid memory access is s.capacity() < 2*s.size() (because s gets resized and possibly moved, so s.begin() and s.end() become invalid references when reading the values to be appended).

  The fix is straightforward: reserve enough space in advance, so that insert() doesn't need to resize and thus its arguments remain valid.

  A simple test case is added as well; though you probably need to run it via valgrind to actually catch the problem when it's not fixed...

  This fixes an issue where estimatesmartfee which matches at the min relay fee will return 999 sat/byte instead of 1000 sat/byte due to a float rounding issue. I went ahead and made all float <-> int conversion outside of test/qt explicit (test only had one or two more, Qt had quite a few, including many in the Qt headers themselves) and added overloads to CFeeRate to force callers to do an explicit round themselves. Easy to test with -Wfloat-conversion.

Pull request description:

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

Pull request description:

  Builds on top of #11117.

  This adds support for:
  * Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
  * Sending to BIP173 addresses (including non-v0 ones)
  * Analysing BIP173 addresses (through `validateaddress`)

  It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.

  Not included (and intended for other PRs):
  * Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
  * Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
  * Error locating in UI for BIP173 addresses.

  This is a greatly simplified version of #10285, which only aims to address async resolving.

  It essentially breaks up two wrapper functions for things only used in one place (ConnectSocketDirectly/ConnectThroughProxy) in favor of calling them directly. This allows us to fully handle resolves before attempting a connection, as is necessary for async connections.

  As a bonus, I believe the logic is now much easier to follow than before.

  This PR also unifies the help text for the `errors` field and its output position so that all of the `get*info` commands are consistent.

  `getnetworkinfo`'s `errors` field is named `warnings`. I did not change this even though it is inconsistent since this naming has been in use for a long time.

382625318d rpc: Handle getinfo locally in bitcoin-cli w/ -getinfo
This adds the infrastructure `BaseRequestHandler` class that takes care
of converting bitcoin-cli arguments into a JSON-RPC request object, and
converting the reply into a JSON object that can be shown as result.

This is subsequently used to handle the `-getinfo` option, which sends
a JSON-RPC batch request to the RPC server with
`["getnetworkinfo", "getblockchaininfo", "getwalletinfo"]`,
and after reply combines the result into what looks like a `getinfo`
result.

There have been some requests for a client-side `getinfo` and this
is my PoC of how to do it. If this is considered a good idea
some of the logic could be moved up to rpcclient.cpp and

Merge #11031: [rpc] deprecate estimatefee
048e0c3e2 [rpc] [tests] Add deprecated RPC test (Cristian Mircea Messel)
d4cdbd6fb [rpc] Deprecate estimatefee RPC (John Newbery)

Pull request description:

  Deprecates estimatefee in v0.16, for final removal in v0.17.

  This commit introduces a phased removal of RPC methods. RPC method is
  disabled by default in version x, but can be enabled by using the
  `-deprecatedrpc=<methodname>` argument. RPC method is removed entirely in version
  (x+1).

  This gives users fair warning that an RPC is to be removed, and time to change client software if necessary. Deprecation warnings in RPC return values or release notes are easily ignored.

  This is a more generic version of the approach I tried to use in #10841, which too late to make it into v0.15.

Merge #11288: More user-friendly error message when partially signing
df10edf More user-friendly error message when partially signing (MeshCollider)

Pull request description:

  When partially signing a transaction using `signrawtransaction`, if the wallet doesn't have access to a key, it will output a scary error message `"error": "Operation not valid with the current stack size"`, yet it will partially sign the transaction anyway. This puts a lot of users off, because they don't realise the signing actually succeeded for some inputs. This catches that specific error when signing, and outputs a friendlier message which says `Unable to sign input, invalid stack size (possibly missing key)`.

  This is the best way I could think of to fix the issue, but please let me know if you come up with a better way to do it :)

13baf72 Replace save|restoreWindowGeometry with Qt functions (MeshCollider)

Pull request description:

  Alternative to https://github.com/bitcoin/bitcoin/pull/11208, closes https://github.com/bitcoin/bitcoin/issues/11207

  According to the [Qt documentation](https://doc.qt.io/qt-4.8/qwidget.html#restoreGeometry), restoreGeometry does all the checks we need, so it would be better to rely on them instead of doing it ourselves.

  ~Haven't tested this properly yet, hence the WIP.~
  Gives expected behavior exactly as the other system apps do based on my tests. Only potential issue is the case when the GUI is almost entirely offscreen with only a single strip of pixels, its not really possible to see the GUI, but if you know it's there you can bring it back onscreen with just the mouse. And that's exactly how notepad behaves on Windows so I don't think its a real issue.

  This also gives much better behavior when closing a maximized window, currently (0.15.0 release) a maximized window will save the window size on close, and then reopen as a not-maximized but still that size, which is really annoying. This reopens as maximized.

1444c2e Switch memory_cleanse implementation to BoringSSL's to ensure memory clearing even with link-time optimization. (Adam Langley)

Pull request description:

  The implementation we currently use from OpenSSL prevents the compiler from optimizing away clensing operations on blocks of memory that are about to be released, but this protection is not extended to link-time optimization. This commit copies the solution cooked up by Google compiler engineers which uses inline assembly directives to instruct the compiler not to optimize out the call under any circumstances. As the code is in-lined, this has the added advantage of removing one more OpenSSL dependency.

  Regarding license compatibility, Google's contributions to BoringSSL library, including this code, is made available under the ISC license, which is MIT compatible.

radio button's text.

a0b4c24617 Trivial: Fix validation comments
- Move comment about transaction/block weight calculation so it applies not only to the GetBlockWeight function but also to GetTransactionWeight
- Fix comment in validation.cpp referencing future deployment of BIP113. It has already been deployed.
- The doc comment for BLOCK_DOWNLOAD_WINDOW wasn't updated since pruning was introduced, so it still refers to pruning as something that might happen in the future. A larger BLOCK_DOWNLOAD_WINDOW window would now, indeed, make pruning harder.

b4058ed9c6 Fix code constness in CBlockIndex::GetAncestor() overloads
Make the non-const overload of CBlockIndex::GetAncestor() reuse the const overload implementation instead of the other way around. This way, the constness of the const overload implementation is guaranteed. The other way around, it was possible to implement the non-const overload in a way which mutates the object, and since that implementation would be called even for const objects (due to the reuse), we would get undefined behavior.

Merge #11332: Fix possible crash with invalid nCustomFeeRadio in QSettings (achow101, TheBlueMatt)
cdaf3a1 Fix Qt 0.14.2->0.15.0 segfault if "total at least" is selected (Matt Corallo)

Pull request description:

  `QButtonGroup->button()` may return a nullptr.
  Accessing the object directly with `setChecked` seems fragile.

  This is a simple fix to ensure to never call a button out of bounds (nullptr).

  There are probably other places where a sanity check for `QSettings` are required.

  Found by @achow101.
  Code by @TheBlueMatt.

fd849e1b03 Change AcceptToMemoryPool function signature
Combine fLimitFree and fOverrideMempoolLimit into a single boolean:
bypass_limits.  This is used to indicate that mempool limiting based on feerate
should be bypassed.  It is used when readding transactions from a reorg and then
the mempool is trimmed to size after all transactions are added and they can be
evaluated in the context of their descendants. No changes to behavior.

0b1b9148cd Remove countMaskInv caching in bench framework
We were saving a div by caching the inverse as a float, but this
ended up requiring a int -> float -> int conversion, which takes
almost as much time as the difference between float mul and div.

There are lots of other more pressing issues with the bench
framework which probably require simply removing the adaptive
iteration count stuff anyway.

* getmininginfo's currentblocksize return value was returning
  garbage values, and has been removed, also removing a
  GetSerializeSize call in some block generation inner loops and
  potentially addressing some performance edge cases.
