dce8c4c381 rpc: getblockfrompeer (Sjors Provoost)
b884ababc2 rpc: move Ensure* helpers to server_util.h (Sjors Provoost)
Pull request description:
This adds an RPC method to fetch a block directly from a peer. This can used to fetch stale blocks with lower proof of work that are normally ignored by the node (`headers-only` in `getchaintips`).
Usage:
```
bitcoin-cli getblockfrompeer HASH peer_n
```
Closes#20155
Limitations:
* you have to specify which peer to fetch the block from
* the node must already have the header

f1f10c0514 Remove CTxMemPool params from ATMP (lsilva01)
Pull request description:
Remove `CTxMemPool` parameter from `AcceptToMemoryPool` function, as suggested in https://github.com/bitcoin/bitcoin/pull/23437#issuecomment-962536149 .
This requires that `CChainState` has access to `MockedTxPool` in `tx_pool.cpp` as mentioned https://github.com/bitcoin/bitcoin/pull/23173#discussion_r731895386. So the `MockedTxPool` is attributed to `CChainState::m_mempool` before calling `AcceptToMemoryPool`.
Requires #23437.

b5696750a9 Test including coinbase transactions in receivedby wallet rpcs (Andrew Toth)
bce20c34d6 Include coinbase transactions in receivedby wallet rpcs (Andrew Toth)
Pull request description:
The current `*receivedby*` RPCs filter out coinbase transactions. This doesn't seem correct since an output to your address in a coinbase transaction *is* receiving those coins.
This PR corrects this behaviour. Also, a new option `include_immature_coinbase` is added (default=`false`) that includes immature coinbase transactions when set to true.
However, since this is potentially a breaking change this PR introduces a hidden configuration option `-deprecatedrpc=exclude_coinbase`. This can be set to revert to previous behaviour. If no reports of broken workflow are received, then this option can be removed in a future release.
Fixes https://github.com/bitcoin/bitcoin/issues/14654.

35d928c632 rpc: deprecate fee fields from mempool entries (josibake)
Pull request description:
per #22682 , top level fee fields for mempool entries have been deprecated since 0.17 but are still returned. this PR properly deprecates them so that they are no longer returned unless `-deprecatedrpc=fees` is passed.
the first commit takes care of deprecation and also updates `test/functional/mempool_packages.py` to only use the `fees` object. the second commit adds a new functional test for `-deprecatedrpc=fees`
closes#22682
## questions for the reviewer
* `-deprecatedrpc=fees` made the most sense to me, but happy to change if there is a name that makes more sense
* #22682 seems to indicate that after some period of time, the fields will be removed all together. if we have a rough idea of when this will be, i can add a `TODO: fully remove in vXX` comment to `entryToJSON`
## testing
to get started on testing, compile, run the tests, and start your node with the deprecated rpcs flag:
```bash
./src/bitcoind -daemon -deprecatedrpc=fees
```
you should see entries with the deprecated fields like so:
```json
{
"<txid>": {
"fees": {
"base": 0.00000671,
"modified": 0.00000671,
"ancestor": 0.00000671,
"descendant": 0.00000671
},
"fee": 0.00000671,
"modifiedfee": 0.00000671,
"descendantfees": 671,
"ancestorfees": 671,
"vsize": 144,
"weight": 573,
...
},
```
you can also check `getmempoolentry` using any of the txid's from the output above.
next start the node without the deprecated flag, repeat the commands from above and verify that the deprecated fields are no longer present at the top level, but present in the "fees" object

1ed5681407 rpc: add missing scantxoutset examples (Sebastian Falbesoner)
Pull request description:
The scantxoutset RPC and its help text was at last improved in #16285, but it's still missing examples (see https://github.com/bitcoin/bitcoin/pull/16285#issuecomment-529313781).
~Note that the example descriptor used doesn't follow the developer guideline of using invalid bech32 addresses, as the RPC is not wallet-related and it's use-case is merely to look up state information (i.e. there is no danger of sending funds to a wrong address).~ For the sake of simplicity, the raw descriptor for an early coinbase payout address (block 9) is taken, i.e. it yields results even at an early stage of IBD. Happy to change that though if there are other suggestions.

29e983386b Fixes Bug in Transaction generation in ComplexMempool benchmark (Shorya)
Pull request description:
This fixes issues with `ComplexMempool` benchmark introduced in [#17292](https://github.com/bitcoin/bitcoin/pull/17292) , this stress test benchmarks performance of ancestor and descendant tracking of mempool graph algorithms on a complex Mempool.
This Benchmark first creates 100 base transactions and stores them in `available_coins` vector. `available_coins` is used for selecting ancestor transactions while creating 800 new transactions. For this a random transaction is picked from `available_coins` and some of its outputs are mapped to the inputs of the new transaction being created.
Now in case we exhaust all the outputs of an entry in `available_coins` then we need to remove it from `available_coins` before the next iteration of choosing a potential ancestor , it is now implemented with this patch.
As the index of the entry is randomly chosen from `available_coins` , In order to remove it from the vector , if index of the selected entry is not at the end of `available_coins` vector , it is swapped with the entry at the back of the vector , then the entry at the end of `available_coins` is popped out.
Earlier the code responsible for constructing outputs of the newly created transaction was inside the loop used for assigning ancestors to the transaction , which does some unnecessary work as it creates outputs of the transaction again and again , now it is moved out of the loop so outputs of the transaction are created just once before adding it to the final list of the transactions created. This one is a minor change to save some computation.
These changes have changed the `ComplexMempool` benchmark results on `bitcoin:master` as follows :
**Before**

| ns/op | op/s | err% | total | benchmark

| 232,881,625.00 | 4.29 | 0.7% | 2.55 | `ComplexMemPool`

0c85dc30e6 p2p: Don't use timestamps from inbound peers (Martin Zumsande)
Pull request description:
`GetAdjustedTime()` (used e.g. in validation and addrman) returns a time with an offset that is influenced by timestamps that our peers have sent us in their version message.
Currently, timestamps from all peers are used for this.
However, I think that it would make sense to ignore the timedata samples from inbound peers, making it much harder for others to influence the Adjusted Time in a targeted way.
With the extra feeler connections (every 2 minutes on average) and extra block-relay-only connections (every 5 minutes on average) there are also now plenty of opportunities to gather a meaningful number of timedata samples from outbound peers.
There are some measures in place to prevent abuse: the `-maxtimeadjustment` parameter with a default of 70 minutes, warnings in cases of large deviations, only using the first 200 samples ([explanation](383d350bd5/src/timedata.cpp (L57-L72))), but I think that only using samples from outbound connections in the first place would be an additional safety measure that would make sense.
See also issue #4521 for further context and links: There have been several discussions in the past about replacing or abolishing the existing timedata system.

31ba1af74a Remove unused (and broken) functionality in SpanReader (Pieter Wuille)
Pull request description:
This removes the ability to set an offset in the `SpanReader::SpanReader` constructor, as the current code is broken since #23653. All call sites use `pos=0`, so it is actually unused. If future call sites need it, `SpanReader{a, b, c, d}` is equivalent to `SpanReader{a, b, c.subspan(d)}`.
It also removes the ability to deserialize from `SpanReader` directly from the constructor. This too is unused, and can be more idiomatically simulated using `(SpanReader{a, b, c} >> x >> y >> z)` instead of `SpanReader{a, b, c, x, y, z}`.

fa37e798b2 wallet: Replace confusing getAdjustedTime() with GetTime() (MarcoFalke)
Pull request description:
Setting `nTimeReceived` to the adjusted time has several issues:
* `m_best_block_time` is set to the "unadjusted" time, thus a comparison of the two times is like comparing apples to oranges. In the worst case this opens up an attack vector where remote peers can force a premature re-broadcast of wallet txs.
* The RPC documentation for `"timereceived"` doesn't mention that the network adjusted time is used, possibly confusing users when the time reported by RPC is off by a few seconds compared to their local timestamp.
Fix all issues by replacing the call with `GetTime()`. Also a style fix: Use non-narrowing integer conversion in the RPC method.
