Merge #17843: wallet: Reset reused transactions cache
6fc554f591 wallet: Reset reused transactions cache (Fabian Jahr)

Pull request description:

  Fixes #17603 (together with #17824)

  `getbalances` is using the cache within `GetAvailableCredit` under certain conditions [here](35fff5be60/src/wallet/wallet.cpp (L1826)). For a wallet with `avoid_reuse` activated this can lead to inconsistent reporting of `used` transactions/balances between `getbalances` and `listunspent` as pointed out in #17603. When an address is reused before the first transaction is spending from this address, the cache is not updated even after the transaction is sent. This means the remaining outputs at the reused address are not showing up as `used` in `getbalances`.

  With this change, any newly incoming transaction belonging to the wallet marks all the other outputs at the same address as dirty.

Pull request description:

  Add logging of `CValidationInterface` callbacks using a new `VALIDATIONINTERFACE` log flag (see #12994). A separate flag is desirable as the logging can be noisy and thus may need to be disabled without affecting other logging.

  This could help debug issues where there may be race conditions at play, such as #12978.

Merge #17445: zmq: Fix due to invalid argument and multiple notifiers
3e730bf90a zmq: Fix due to invalid argument and multiple notifiers (João Barbosa)

Pull request description:

  ZMQ initialization is interrupted if any notifier fails, and in that case all notifiers are destroyed. The notifier shutdown assumes that the initialization had occurred. This is not valid when there are multiple notifiers and any except the last fails to initialize.

  Can be tested by running test/functional/interface_zmq.py from this branch with bitcoind from master.

  Closes #17185.

60aba1f2f1 rpc: simplify getaddressinfo labels, deprecate previous behavior (Jon Atack)
7851f14ccf rpc: incorporate review feedback from PR 17283 (Jon Atack)

Pull request description:

  This PR builds on #17283 (now merged) and is followed by #17585.

  It modifies the value returned by rpc getaddressinfo `labels` to an array of label name strings and deprecates the previous behavior of returning an array of JSON hash structures containing label `name` and address `purpose` key/value pairs.

  before
  ```
    "labels": [
      {
        "name": "DOUBLE SPEND",
        "purpose": "receive"
      }
  ```
  after
  ```
    "labels": [
      "DOUBLE SPEND"
    ]
  ```

  The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=labelspurpose`.

  For context, see:
  - https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001
  - http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-13.html#l-425 (lines 425-427)
  - http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622

  Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=labelspurpose` flag while verifying the rpc getaddressinfo help text and `labels` output.

  Next steps: deprecate the rpc getaddressinfo `label` field (EDIT: done in #17585) and add support for multiple labels per address. This PR will unblock those.

Merge #17728: rpc: require second argument only for scantxoutset start action
7d263571be rpc: require second argument only for scantxoutset start action (Andrew Chow)

Pull request description:

  It was reported on [IRC](http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-11.html#l-377) that `scantxoutset`'s API was broken in 0.19.0:

  ```
  <belcher> i think scantxoutset may have been broken in bitcoin core 0.19 ? regardless of what parameters i run it with (e.g. "scantxoutset abort", "scantxoutset status") it just returns the help doc, according to the release notes the only change was https://github.com/bitcoin/bitcoin/pull/16285/files but i dont see anything that wouldve broken it, it works fine in 0.18
  <belcher> im on regtest, in case its important
  <harding> I can confirm `scantxoutset abort` returns the help doc on latest master.  Waiting for 0.18.1 to start now to attempt to reproduce there.
  <harding> It looks like it's expecting a second parameter (even though that doesn't make sense with "abort").
  <jonatack> Same for me as well
  <harding> Can also confirm that `scantxoutset abort` returns the expected result on 0.18.1.
  ```

  As noted in the conversation, previously, the second argument of `scanobjects` is only required for the `start` action. `Stop` and `abort` actions did not and could work without them.

  It appears that this was broken by #16240 which enforced the size of the arguments to match the listed required arguments.

  To fix this issue, this PR makes the `scanobjects` argument an optional argument. Then only in the `start` action do we check whether the `scanobjects` argument is there and throw an informative error about that. Also a test is added for this case.

Merge #12763: Add RPC Whitelist Feature from #12248
2081442c42 test: Add test for rpc_whitelist (Emil Engler)
7414d3820c Add RPC Whitelist Feature from #12248 (Jeremy Rubin)

Pull request description:

  Summary
  ====

  This patch adds the RPC whitelisting feature requested in #12248. RPC Whitelists help enforce application policies for services being built on top of Bitcoin Core (e.g., your Lightning Node maybe shouldn't be adding new peers). The aim of this PR is not to make it advisable to connect your Bitcoin node to arbitrary services, but to reduce risk and prevent unintended access.

  Using RPC Whitelists
  ====
  The way it works is you specify (in your bitcoin.conf) configurations such as

  ```
  rpcauth=user1:4cc74397d6e9972e5ee7671fd241$11849357f26a5be7809c68a032bc2b16ab5dcf6348ef3ed1cf30dae47b8bcc71
  rpcauth=user2:181b4a25317bff60f3749adee7d6bca0$d9c331474f1322975fa170a2ffbcb176ba11644211746b27c1d317f265dd4ada
  rpcauth=user3:a6c8a511b53b1edcf69c36984985e$13cfba0e626db19061c9d61fa58e712d0319c11db97ad845fa84517f454f6675
  rpcwhitelist=user1:getnetworkinfo
  rpcwhitelist=user2:getnetworkinfo,getwalletinfo, getbestblockhash
  rpcwhitelistdefault=0
  ```

  Now user1 can only call getnetworkinfo, user2 can only call getnetworkinfo or getwalletinfo, while user3 can still call all RPCs.

  If any rpcwhitelist is set, act as if all users are subject to whitelists unless rpcwhitelistdefault is set to 0. If rpcwhitelistdefault is set to 1 and no rpcwhitelist is set, act as if all users are subject to whitelists.

  Review Request
  =====
  In addition to normal review, would love specific review from someone working on LN (e.g., @ roasbeef) and someone working on an infrastructure team at an exchange (e.g., @ jimpo) to check that this works well with their system.

  Notes
  =====

  The rpc list is spelling sensitive -- whitespace is stripped though. Spelling errors fail towards the RPC call being blocked, which is safer.

  It was unclear to me if HTTPReq_JSONRPC is the best function to patch this functionality into, or if it would be better to place it in exec or somewhere else.

  It was also unclear to me if it would be preferred to cache the whitelists on startup or parse them on every RPC as is done with multiUserAuthorized. I opted for the cached approach as I thought it was a bit cleaner.

  Future Work
  =====

  In a future PR, I would like to add an inheritance scheme. This seemed more controversial so I didn't want to include that here. Inheritance semantics are tricky, but it would also make these whitelists easier to read.

  It also might be good to add a `getrpcwhitelist` command to facilitate permission discovery.

  Tests
  =====
  Thanks to @ emilengler for adding tests for this feature. The tests cover all cases except for where `rpcwhitelistdefault=1` is used, given difficulties around testing with the current test framework.
