da0b8e2ce1 refactor: drop unneeded MIN_PEER_PROTO_VERSION from RelayInv (pasta)
94da0de6ef refactor: implement minimal RelayInv which doesn't rely on m_connman (pasta)
Pull request description:
## Issue being fixed or feature implemented
Vast majority of usages of RelayInv don't use the minProtoVersion, we may as well have these not contribute to contention of m_nodes_mutex / use m_connman
## What was done?
new implementation of RelayInv which doesn't rely on m_connman
## How Has This Been Tested?
See CI

0a63029c96 feat: increase threshold from 2000 DASH to 21M DASH for CJ amount in option (Konstantin Akimov)
Pull request description:
## Issue being fixed or feature implemented
With rpc and command line option you can choose any amount of CJ (threshold to stop), but UI let to choose maximum 2000 Dash.
Assuming, that Evo collateral is 4000 it's unwisely to limit UI to just 2k.
## What was done?
Limits are increased to `MAX_COINJOIN_AMOUNT` (21M)
## How Has This Been Tested?
Run UI and set

Pull request description:
This PR has important fixes to implement "single-node quorum" feature.
## Issue being fixed or feature implemented
Without IS-quorum you can not dynamically add a new MN or Evo node.
For evo nodes adding it dynamically is the only way.
## What was done?
Fixed a function that dynamically adds a masternode without Instant Send quorums; use it in a functional test feature_asset_locks.py
As side effect it improves performance of functional tests which do not wait more IS lock significantly; for feature_asset_locks.py it gave ~20 seconds per run.
## How Has This Been Tested?

6f75a7f601 refactor: use swap instead assign+clean in GetAndClearDirtyGovernanceObjectHashes (Konstantin Akimov)
83e0bb6e35 fix: potential bug due to unspecified state of std::vector after move (Konstantin Akimov)
Pull request description:
## Issue being fixed or feature implemented
All standard library objects that have been moved from are placed in a "valid but unspecified state", meaning the object's class invariants hold (so functions without preconditions, such as the assignment operator, can be safely used on the object after it was moved from). See example:
```
std::vector<int> v = {2, 3, 3};
std::vector<int> u = std::move(v); // the value of v is unspecified
v.clear(); // we are good now
```
Instead, let's have swap better!
```
WITH_LOCK(cs_pendingSigns, v.swap(pendingSigns));
```
## What was done?
Fixed `CSigSharesManager::SignPendingSigShares`, `CSigningManager::ProcessPendingReconstructedRecoveredSigs` and refactored `CMasternodeMetaMan::GetAndClearDirtyGovernanceObjectHashes` for unification.
## How Has This Been Tested?
Run unit and functional tests.

0c85dc30e6b628f7538a67776c7eefcb84ef4f82 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.

## Additional Information
* This pull request's primary purpose is to restore `LogPrintLevel`s from backports in [dash#6333](https://github.com/dashpay/dash/pull/6333) that were changed to `LogPrint`s as they were backported before `LogPrintLevel` was backported.
* ~~`clang-format` suggestions for `LogPrintLevel` have to be ignored in order to prevent the linter from tripping due to a "missing newline" ([build](https://gitlab.com/dashpay/dash/-/jobs/8398818860#L54)).~~ Resolved by applying diff ([source](https://github.com/dashpay/dash/pull/6399#issuecomment-2488992710)).
* `SharedLock` was introduced in [dash#5961](https://github.com/dashpay/dash/pull/5961) and `PrintLockContention` was removed in [dash#6046](https://github.com/dashpay/dash/pull/6046) but the changes in the latter were not extended to the former. This has been corrected as part of this pull request.

dafa7363a3 fix: respect SENDDSQUEUE message, move DSQ relay into net processing / peerman (pasta)
Pull request description:
## Issue being fixed or feature implemented
in #6148, I broke the functionality where a peer must opt in / opt out of DSQUEUE messages. This was mostly ok, and not immediately detected, as with this bug, simply everyone would receive DSQ messages over inventory (or classically, old proto versions were not affected by this bug). But this still would result in quite a bit of wasted bandwidth for peers which may not care about DSQ at all.
## What was done?
This commit should restore the prior functionality, where a node should send the SENDDSQUEUE message if they wish to receive DSQs. Once they've sent that, depending on their protocol version, they will either have the messages pushed to them as available, or on modern protocols, they will thereafter receive DSQs over the inventory system.
NOTE: I also refactor the code in this commit, moving some network proccessing into.... wait for it... net_processing.cpp! This allowed us to remove some dependencies in coinjoin.h. DSQ messages are now relayed to peers by calling peer_manager.RelayDSQ
## How Has This Been Tested?
I have not yet mixed on testnet with this; we should include it in rc.2 and test
## Breaking Changes
Slightly breaking for v22.0.x (so rc.1), as they in theory could be relying on this new logic of always receiving the DSQ inv. But I don't think anyone besides core is using this new protocol.

f39c1e6f4c fix: guard m_can_tx_relay behind m_tx_relay_mutex; make it private; add additional annotations (pasta)
Pull request description:
## Issue being fixed or feature implemented
See each commit; fixes two bugs, both discovered while running feature_llmq_chainlocks.py with tsan / debug.
one a datarace in net_processing.cpp and the other in the test I was using to ensure this fix was correct, feature_llmq_chainlocks
## What was done?
### net_processing.cpp
You can see the datarace here: https://gist.github.com/PastaPastaPasta/c966a9f805758b34524085e3d52ea7f8
We simply guard it with an existing mutex that is always locked in close proximity.
### feature_llmq_chainlocks.py
Most of the time, while generating the cycle quorum, there is sufficient time to generate a chainlock; however, this is racey, and I've observed locally where the block gets generated before a chainlock is present and as such `test_coinbase_best_cl` fails. We should instead wait for the chainlock first, and then mine the block. This was we can ensure the mined block will include that chainlock.
This was observed locally maybe 1/10 times or so
## How Has This Been Tested?
ran feature_llmq_chainlocks.py ~40 times locally with tsan / debug
## Breaking Changes
None

Pull request description:

It affects behavior on new devnets and regtest for pre-mn_rr activation blocks.

## What was done?
changed depends/${{ matrix.host }} to depends/built as gitlab does
## How Has This Been Tested?
Depends "build" now takes only ~1 minute instead of ~15 minutes in CI: https://github.com/PastaPastaPasta/dash/actions/runs/11899038167
