Currently, if BroadcastTransaction() is called to rebroadcast a
transaction (e.g. by ResendWalletTransactions()), then we add the
transaction to the unbroadcast set. That transaction has already been
broadcast in the past, so peers are unlikely to request it again,
meaning RemoveUnbroadcastTx() won't be called and it won't be removed
from m_unbroadcast_txids.
Net processing will therefore continue to attempt rebroadcast for the
transaction every 10-15 minutes. This will most likely continue until
the node connects to a new peer which hasn't yet seen the transaction
(or perhaps indefinitely).
Fix by only adding the transaction to the broadcast set when it's added
to the mempool.
b7a8cd9963 [test] submit same txid different wtxid as mempool tx (glozow)
fdb48163bf [validation] distinguish same txid different wtxid in mempool (glozow)
Pull request description:
On master, if you submit a transaction with the same txid but different witness to the mempool, it thinks the transactions are the same. Users submitting through `BroadcastTransaction()` (i.e. `sendrawtransaction` or the wallet) don't get notified that there's a different transaction in the mempool, although it doesn't crash. Users submitting through `testmempoolaccept()` will get a "txn-already-in-mempool" error.
This PR simply distinguishes between `txn-already-in-mempool` and `txn-same-nonwitness-data-in-mempool`, without handling them differently: `sendrawtransaction` still will not throw, but `testmempoolaccept` will give you a different error.
I believe the intention of #19645 is to allow full swaps of transactions that have different witnesses but identical nonwitness data. Returning a different error message + adding a test was suggested: https://github.com/bitcoin/bitcoin/pull/19645#issuecomment-705109193 so this is that PR.

This is a temporary change to convert I2P addresses that have propagated
with port 8333 to ones with port 0.
It would cause a problem some day if indeed some bitcoin software is
listening on port 8333 only and rejects connections to port 0 and we are
still using SAM 3.1 which only supports port 0. In this case we would
replace 8333 with 0 and try to connect to such nodes.
This commit should be included in 22.0 and be reverted before 23.0 is
released.
When connecting to an I2P host we don't specify destination port and it
is being forced to 0 by the SAM 3.1 proxy, so if we connect to the same
host on two different ports, that would be actually two connections to
the same service (listening on port 0).
Fixes https://github.com/bitcoin/bitcoin/issues/21389
* When accepting an I2P connection, assume the peer has port 0 instead
of the default 8333 (for mainnet). It is not being sent to us, so we
must assume something.
* When deriving our own I2P listen CService use port 0 instead of the
default 8333 (for mainnet). So that we later advertise it to peers
with port 0.
In the I2P protocol SAM 3.1 and older (we use 3.1) ports are not used,
so they are irrelevant. However in SAM 3.2 and newer ports are used and
from the point of view of SAM 3.2, a peer using SAM 3.1 seems to have
specified port=0.

61b6a017a9 test: wallet util: fix multisig P2SH-P2WSH script creation (Sebastian Falbesoner)
Pull request description:
PR #18788 (commit 08067aebfd) introduced functions to generate output scripts for various types. This PR replaces all manual CScript creations in the P2PKH, P2SH, P2WPKH, P2WSH formats with those helpers in order to increase readability and maintainability over the functional test codebase. The first commit fixes a bug in the wallet_util helper module w.r.t. to P2SH-P2WSH script creation (the result is not used in any test so far, hence it can still be seen as refactoring).
The following table shows a summary of the output script patterns tackled in this PR:
| Type | master branch | PR branch |
| ---------- | ------------- | ------------- |
| P2PKH | `CScript([OP_DUP, OP_HASH160, hash160(key), OP_EQUALVERIFY, OP_CHECKSIG])` | `key_to_p2pkh_script(key)` |
| | `CScript([OP_DUP, OP_HASH160, keyhash, OP_EQUALVERIFY, OP_CHECKSIG])` | `keyhash_to_p2pkh_script(keyhash)` |
| P2SH | `CScript([OP_HASH160, hash160(script), OP_EQUAL])` | `script_to_p2sh_script(script)` |
| P2WPKH | `CScript([OP_0, hash160(key)])` | `key_to_p2wpkh_script(key)` |
| P2WSH | `CScript([OP_0, sha256(script)])` | `script_to_p2wsh_script(script)` |
Note that the `key_to_...` helpers can't be used if an invalid key size (not 33 or 65 bytes) is passed, which is the case in some rare instances where the scripts still have to be created manually.
Possible follow-up ideas:
* further simplify by identifying P2SH-wrapped scripts and using `key_to_p2sh_p2wpkh_script()` and `script_to_p2sh_p2wsh_script()` helpers
* introduce and use `key_to_p2pk_script()` helper for P2PK scripts

Pull request description:
This is #20980 rebased (to include the Boost Process fix), and with an additional commit (892d6897f1e613084aa0517a660eab2412308e6e) to fix running the `test-security-check` target for the macOS build. It should pass inside Guix, as well as when cross-compiling on Ubuntu, or building natively on macOS.
Note that the `test-security-check` may output some warnings (similar too):
```bash
ld: warning: passed two min versions (10.14, 11.4) for platform macOS. Using 11.4.
ld: warning: passed two min versions (10.14, 11.4) for platform macOS. Using 11.4.
ld: warning: passed two min versions (10.14, 10.14) for platform macOS. Using 10.14.
```
but those can be ignored, and come about due to us passing `-platform_version` when `-mmacosx-version-min` is already part of `CC`.

aa0a5bb70d test: add `bad-txns-prevout-null` test case to invalid_txs.py (Sebastian Falbesoner)
Pull request description:
This simple PR adds missing tests for the reject reason `bad-txns-prevout-null`, which is thrown in the function `CheckTransaction()`: a62fc35a15/src/consensus/tx_check.cpp (L52-L54)
Basically this condition is met for non-coinbase transactions (the code snippet above only hits if `!tx.IsCoinBase()`) with coinbase-like outpoints, i.e. hash=0, n=0xffffffff.
Can be tested by running the functional tests `feature_block.py`, `p2p_invalid_tx.py` and `mempool_accept.py`. Not sure if the redundancy in the tests is desired (I guess it would make sense if the mempool acceptance test also makes use of the invalid_txs templates?).

and has no candidates remaining to be protected in later iterations.

Thank you to Vasil Dimov, whose suggestions during a post-merge
discussion about PR 21261 reminded me that I had done this in
earlier versions of the PR, e.g. commits like ef411cd2.

The semantic of `-bind` is to restrict the binding only to some address.
If not specified, then the user does not care and we bind to `0.0.0.0`.
If specified then we should honor the restriction and bind only to the
specified address.
Before this change, if no `-bind` is given then we would bind to
`0.0.0.0:8333` and to `127.0.0.1:8334` (incoming Tor) which is ok -
the user does not care to restrict the binding.
However, if only `-bind=addr:port=onion` is given (without ordinary
`-bind=`) then we would bind to `addr:port` _and_ to `0.0.0.0:8333` in
addition.
Change the above to not do the additional bind: if only
`-bind=addr:port=onion` is given (without ordinary `-bind=`) then bind
to `addr:port` (only) and consider incoming connections to that as Tor
and do not advertise it. I.e. a Tor-only node.
cdb41d5573 doc: Install Rosetta on M1-macOS for qt in depends (Hennadii Stepanov)
Pull request description:
On master (c609e10545) `make -C depends qt` on Apple Silicon based macOS 11.4 ends with an error:
```
/bin/sh: /Users/hebasto/bitcoin/depends/work/build/aarch64-apple-darwin20.5.0/qt/5.12.11-6c4d47a8f8f/qtbase/bin/moc: Bad CPU type in executable
```
Installing Rosetta 2 fixes it.
Explanation. On Apple Silicon macOS the `qt` package in depends actually is cross compiled. All native tools (including `moc`) are x86_64 binaries, that require Rosetta 2 to run.

Now that our release binaries are build in a glibc 2.24 and 2.27
environment, we can't use a symbol from glibc 2.28 to test our checks.
Replace renameat2() with nextup(), which was introduced in 2.24.
Note that this also means re-disabling the test for RISC-V, however
RISC-V is built in a glibc 2.27 environment, and our minimum required
glibc for that binary is 2.27.
We use these flags in our test-security-check make target, but they are
only available because debian patches them in.
We can patch them in for our Guix builds so that we can check the sanity
of our security/symbol checking suite before running them.
This is important to make sure that we're not testing tools different
from the one we're building with.
Introduce determine_wellknown_cmd, which encapsulates how we
should handle well-known tools specification (IFS splitting, env
override, etc.).

Pull request description:
Now that our Guix toolchains are based on glibc 2.24 and 2.27 (RISCV), we don't need to use the `--enable-glibc-back-compat` option to produce binaries that don't use any symbols from glibc 2.17 and 2.27 or later.
This also adds additional documentation to some Guix patches (pointed out in #22365) and removes Guix patches from the spelling linter, because that isn't our spelling.

Now that our Guix builds are performed on glibc 2.24 and 2.27 (RISCV),
we no-longer need to pass the --enable-glibc-back-compat option.
Replace it with --disable-threadlocal, to prevent the usage of symbols
from glibc 2.18.
None of the binaries produced required symbols later than 2.17, and 2.27
(RISCV).
