When trying to add an address to the IP address manager tried table,
it's first added to the new table and then moved to the tried table.
Previously, adding a conflicting address to the address manager's
tried table with test-only `addpeeraddress tried=true` RPC would
return `{ "success": true }`. However, the address would not be added
to the tried table, but would remain in the new table. This caused,
e.g., issue 28964.
This is fixed by returning `{ "success": false, "error":
"failed-adding-to-tried" }` for failed tried table additions. Since
the address remaining in the new table can't be removed (the address
manager interface does not support removing addresses at the moment
and adding this seems to be a bigger effort), an error message is
returned. This indicates to a user why the RPC failed and allows
accounting for the extra address in the new table.
Also:
To check the number of addresses in each addrman table,
the addrman checks were re-run and the log output of this check
was asserted. Ideally, logs shouldn't be used as an interface
in automated tests. To avoid asserting the logs, use the getaddrmaninfo
and getrawaddrman RPCs (which weren't implemented when the test was added).
Removing the "getnodeaddress" calls would also remove the addrman checks
from the test, which could reduce the test coverage. To avoid this,
these are kept.
626f8e398e fuzz: actually test garbage >64b in p2p transport test (Pieter Wuille)
Pull request description:
This fixes an oversight from #28196: in the `p2p_transport_bidirectional_v2` fuzz test, when the desired garbage length is over 64 bytes, the code would actually use garbage length 0. Fix this.

38f70ba6ac RPC: Add maxfeerate and maxburnamount args to submitpackage (Greg Sanders)
Pull request description:
Resolves https://github.com/bitcoin/bitcoin/issues/28949
I couldn't manage to do it very cleanly outside of (sub)package evaluation itself, since it would change the current interface very heavily. Instead I threaded through the max fee argument and used that directly via ATMPArgs. From that perspective, this is somewhat a reversion from https://github.com/bitcoin/bitcoin/pull/19339. In a post-cluster mempool world, these checks could be consolidated to right after the given (ancestor) package is linearized/chunked, by just checking the feerate of the top chunk and rejecting the submission entirely if the top chunk is too high.
The implication here is that subpackages can be submitted to the mempool prior to hitting this new fee-based error condition.

The `PopulateAndValidateSnapshot` function introduced in
f6e2da5fb7 from #19806 has been setting fake
`nTx` and `nChainTx` values that can show up in RPC results (see #29328) and
make `CBlockIndex` state hard to reason about, because it is difficult to know
whether the values are real or fake.
Revert to previous behavior of setting `nTx` and `nChainTx` to 0 when the
values are unknown, instead of faking them.
This commit fixes at least two assert failures in the (pindex->nChainTx ==
pindex->nTx + prev_chain_tx) check that would happen previously. Tests for
these failures are added separately in the next two commits.
Compatibility note: This change could result in -checkblockindex failures if a
snapshot was loaded by a previous version of Bitcoin Core and not fully
validated, because fake nTx values will have been saved to the block index. It
would be pretty easy to avoid these failures by adding some compatibility code
to `LoadBlockIndex` and changing `nTx` values from 1 to 0 when they are fake
(when `(pindex->nStatus & BLOCK_VALID_MASK) < BLOCK_VALID_TRANSACTIONS`), but a
little simpler not to worry about being compatible in this case.

This new function takes the populated sets of

The diagram check only works against cluster
sizes of 2 or less, and fails if it encounters
a different topology.

28287cfbe1 test: add script compression coverage for not-on-curve P2PK outputs (Sebastian Falbesoner)
Pull request description:
This PR adds unit test coverage for the script compression functions `{Compress,Decompress}Script` in the special case of uncompressed P2PK outputs (scriptPubKey: OP_PUSH65 <0x04 ....> OP_CHECKSIG) with [pubkeys that are not fully valid](44b05bf3fe/src/pubkey.cpp (L297-L302)), i.e. where the encoded point is not on the secp256k1 curve. For those outputs, script compression is not possible, as the y coordinate of the pubkey can't be recovered (see also call-site of `IsToPubKey`):
44b05bf3fe/src/compressor.cpp (L49-L50)
Likewise, for a compressed script of an uncompressed P2PK script (i.e. compression ids 4 and 5) where the x coordinate is not on the curve, decompression fails:
44b05bf3fe/src/compressor.cpp (L122-L129)
Note that the term "compression" is used here in two different meanings (though they are related), which might be a little confusing. The encoding of a pubkey can either be compressed (33-bytes with 0x02/0x03 prefixes) or uncompressed (65-bytes with 0x04 prefix). On the other hand there is also compression for whole output scripts, which is used for storing scriptPubKeys in the UTXO set in a compact way (and also for the `dumptxoutset` result, accordingly). P2PK output scripts with uncompressed pubkeys get compressed by storing only the x-coordinate and the sign as a prefix (0x04 = even, 0x05 = odd). Was diving deeper into the subject while working on https://github.com/bitcoin/bitcoin/pull/27432, where the script decompression of uncompressed P2PK needed special handling (see also https://github.com/bitcoin/bitcoin/issues/24628#issuecomment-1108798536).
Trivia: as of now (block 801066), there are 13 uncompressed P2PK outputs in the UTXO set with a pubkey not on the curve (which obviously means they are unspendable).

07cd510ffe [refactor] consolidate invalid MempoolAcceptResult processing (glozow)
9353aa4066 [refactor] consolidate valid MempoolAcceptResult processing (glozow)
Pull request description:
Every time we try to `ProcessTransaction` (i.e. submit a tx to mempool), we use the result to update a few net processing data structures. For example, after a failure, the {wtxid, txid, both, neither} (depending on reason) should be cached in `m_recent_rejects` so we don't try to download/validate it again.
There are 2 current places and at least 1 future place where we need to process `MempoolAcceptResult`:
- In the `ProcessMessage` logic after receiving and validating a tx
- In `ProcessOrphanTx` where we retry orphans
- With #28970, after processing a package of transactions, we should do these updates for each tx in the package.
Consolidate this code so it isn't repeated in 2 places and so we can reuse it in a future PR.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27252
UNIX domain sockets are a mechanism for inter-process communication that are faster than local TCP ports (because there is no need for TCP overhead) and potentially more secure because access is managed by the filesystem instead of serving an open port on the system.
There has been work on [unix domain sockets before](https://github.com/bitcoin/bitcoin/pull/9979) but for now I just wanted to start on this single use-case which is enabling unix sockets from the client side, specifically connecting to a local Tor proxy (Tor can listen on unix sockets and even enforces strict curent-user-only access permission before binding) configured by `-onion=` or `-proxy=`
I copied the prefix `unix:` usage from Tor. With this patch built locally you can test with your own filesystem path (example):
`tor --SocksPort unix:/Users/matthewzipkin/torsocket/x`
`bitcoind -proxy=unix:/Users/matthewzipkin/torsocket/x`
Prep work for this feature includes:
- Moving where and how we create `sockaddr` and `Sock` to accommodate `AF_UNIX` without disturbing `CService`
- Expanding `Proxy` class to represent either a `CService` or a UNIX socket (by its file path)
Future work:
- Enable UNIX sockets for ZMQ (https://github.com/bitcoin/bitcoin/pull/27679)
- Enable UNIX sockets for I2P SAM proxy (some code is included in this PR but not tested or exposed to user options yet)
- Enable UNIX sockets on windows where supported
- Update Network Proxies dialog in GUI to support UNIX sockets

Pull request description:
Revives #17167. It allows whitelisting manual connections. Fixes #9923
Since there are some PRs/issues around this topic, I'll list some motivations/comments for whitelisting outbound connections from them:
- Speed-up tx relay/mempool sync for testing purposes (my personal motivation for this) - In #26970, theStack pointed out that we whitelist peers to speed up tx relay for fast mempool synchronization, however, since it applies only for inbound connections and considering the topology `node0 <--- node1 <---- node2 <--- ... <-- nodeN`, if a tx is submitted from any node other than node0, the mempool synchronization can take quite long.
- https://github.com/bitcoin/bitcoin/pull/29058#issuecomment-1865155764 - "Before enabling -v2transport by default (which I'd image may happen after https://github.com/bitcoin/bitcoin/pull/24748) we could consider a way to force manual connections to be only-v1 or even only-v2 (disabling reconnect-with-v1). A possibility could be through a net permission flag, if https://github.com/bitcoin/bitcoin/pull/27114 makes it in."
- https://github.com/bitcoin/bitcoin/pull/17167#issuecomment-1168606032 - "This would allow us to use https://github.com/bitcoin/bitcoin/pull/25355 when making outgoing connections to all nodes, except to whitelisted ones for which we would use our persistent I2P address."
