Issue being fixed or feature implemented

Extended addresses (version 3 ProTx) let a masternode list IPv6 and privacy-network addresses. The rest of the system still expects masternodes to reach each other over IPv4:

• GetPrimary() returns the first Core P2P entry. Peers and quorum members dial that address, and CActiveMasternodeManager only accepts an IPv4 local address to match it.
• The legacy platformP2PPort/platformHTTPPort fields assume Platform runs on the Core address.

ExtNetInfo enforced none of this. Once v24 is active, a version 3 ProTx could leave a masternode with no IPv4 primary at all and point its Platform endpoints at other addresses. The draft spec for the format (DIP-0003 Appendix C, dashpay/dips#164) pins those first entries.

Testnet already has version 3 ProTxs that break those rules (the first at height 1584322). Enforcing the rules there from v24 activation would make a node syncing testnet from scratch reject those blocks. So the rule is tied to an activation rather than to a network.

What was done?

1. IPv4 primaries until masternodes may run without IPv4 (fix(evo): require IPv4 primary addresses until masternodes may run without IPv4)

Until a new DEPLOYMENT_IPV4_OPTIONAL is active:

• the first coreP2PAddrs entry must be IPv4 (bad-protx-netinfo-addr-type);
• an EvoNode's first platformP2PAddrs and platformHTTPSAddrs entries must be IPv4 (bad-protx-netinfo-addr-type) and use that same address (bad-protx-netinfo-addr).

Additional entries may use any supported type and address, as before.

The activation itself isn't defined yet; no bit or signalling is assigned. It's a placeholder buried-style height, so the rule is written once with no network branch:

Network	IPv4OptionalHeight	Effect
mainnet	never (INT_MAX)	rule enforced
testnet	always (0)	unchanged: no rule, so mined history stays valid
devnet	always (0)	unchanged, same as testnet
regtest	never by default; -testactivationheight=ipv4_optional@<height>	rule enforced, like mainnet, unless set

When the real deployment is defined, DEPLOYMENT_IPV4_OPTIONAL can move to a version-bits (EHF) deployment. Every production caller evaluates it through the chainman overloads, so none of them will need changing. A note on IPv4OptionalHeight lists what will need attention:

• testnet and devnets must stay ALWAYS_ACTIVE to keep their history valid;
• the mainnet first-entry port pins below don't depend on the activation. So even after the relaxation, a first entry that can't use the standard port, such as I2P (port 0), stays invalid on mainnet.

The deployment is also deliberately left out of getdeploymentinfo, so the RPC's output won't change type when the real deployment replaces the placeholder.

The rule depends on the block a ProTx is mined in. So it's checked in CheckProviderNetworkFields() through SpecialTxRules::ipv4_optional, which GetSpecialTxRules(pindexPrev) computes for block validation, the mempool, the miner, InstantSend signing and RPC Preflight. It is deliberately not in ExtNetInfo::Validate(). Snapshot loading runs Validate() on stored masternode states without a height, so stored states and snapshots load as before on every network.

The protx RPCs evaluate the rule at the chain tip when they build a transaction.

The GUI validates typed endpoints on every keystroke, so it must not take cs_main there. Instead, ProviderTxCapabilities now carries ipv4_optional, computed under the same lock as the provider version. validateProviderNetInfo/findProviderNetInfoInUse take the flag from the caller's capability snapshot, and ValidateNetInfo() no longer touches the node. The wizard's Platform page pins the flag along with the version it entered with.

A stale snapshot only affects the pre-check, as the version already could: submission rechecks against the active rules.

CheckProUpServTx now takes SpecialTxRules, like CheckProRegTx.

2. Mainnet primary ports (fix(evo): pin the mainnet ports of version 3 primary provider addresses)

Legacy ProTxs already require Core on 9999 and Platform on 26656/443 on mainnet. The draft spec keeps that for the first entry of each purpose ("On mainnet, MUST use port of ..."). This port policy stays network-specific, as it is for legacy ProTxs:

• On mainnet, the first entry of each purpose must use 9999, 26656 or 443 respectively.
• Additional entries only follow the general port rules, which are unchanged, so they may use the standard ports too. For example, a second IPv4 address can serve Core on 9999 and Platform on 26656/443.

This depends only on the network, so it lives in ExtNetInfo::Validate() and AddEntry(). Violations get bad-protx-netinfo-port.

Also updated: RPC help, a release note, the core_write.cpp comment on the legacy Platform port fields, and the wizard's HTTPS placeholder (now an IP rather than a domain).

Activation and compatibility

• Version 3 ProTxs are only valid once v24 is active. v24 isn't active on mainnet, so no existing mainnet transaction or state is affected.
• Legacy ProTxs can't break either rule: they are IPv4-only and already use these ports on mainnet. A legacy masternode's carried-over Core entry passes both rules when it moves to version 3.
• Testnet and devnet behaviour is unchanged for both rules.

Deployment: mainnet v24 signalling starts on 2026-11-09. Both rules tighten mainnet validation of version 3 ProTxs, so this must ship in v24.0.0 final and run on the masternodes before v24 activates on mainnet. Hence the 24 milestone and the backport label.

How Has This Been Tested?

Unit tests (src/test/evo_netinfo_tests.cpp):

• ipv4_primaries_follow_activation: checks the activation status on mainnet and testnet. It then builds rule-breaking and valid layouts and runs CheckProviderNetworkFields with the activation on and off, on testnet and again after deserializing under mainnet params. The rejections and reasons follow the activation, not the network, and Validate() accepts every layout.
• provider_network_fields_main: goes through validateProviderNetInfo under mainnet without a chain. It covers valid multi-address layouts, the bare-port form, each port violation (named per entry) and each IPv4/address violation (by reject reason). With the relaxed flag, the IPv4/address rows are accepted, and a non-standard first port is still rejected.
• extnetinfo_ports_mainnet_only: port layouts are accepted on testnet. Deserialized under mainnet, those with a non-standard first port are rejected by both Validate() and CheckProviderNetworkFields. A layout with additional IPv4 and domain entries on the standard ports is accepted.
• provider_network_fields_main also accepts additional addresses on the standard ports, such as a second IPv4 address on 9999/26656/443.

Other unit and Qt tests:

• interfaces_tests:
  • getProviderTxCapabilities() reports ipv4_optional false on default regtest, and true when -testactivationheight activates it at height 1;
  • validateProviderNetInfo completes while another thread holds cs_main.
• The Update Service dialog test checks that the dialog follows its snapshot's flag, and that typing in it doesn't wait for cs_main.
• Re-adding a cs_main lock to validateProviderNetInfo makes both threading checks fail.
• The snapshot fixture keeps a Platform address that differs from Core and a domain as the first HTTPS entry, and it still round-trips under mainnet params. Its golden hash changed only because a Platform port moved from 26657 to 26656.
• The Qt widget and maintenance tests put their version 3 EvoNodes' Platform primaries on the Core address. providerNetInfoValidation now creates its own mainnet setup instead of relying on the params and context left by an earlier test.

test/functional/rpc_netinfo.py sets the ipv4_optional activation height to 500 with -testactivationheight:

• Below the activation height, the RPCs reject a registration and an update for each violation.
• At the activation height, the same transactions pass testmempoolaccept. After invalidateblock steps back one block, the mempool rejects them with the consensus reject reasons, and so does generateblock (TestBlockValidity).
• The test's remaining checks then run with the rule relaxed.

Mutation checks (each makes a test fail):

• the rule never applied; the activation ignored; the same-address check removed;
• testnet not always active; mainnet active;
• GetSpecialTxRules always permissive or always strict;
• the first-entry port pin removed from Validate()/AddEntry();
• the former ban on additional IPv4 entries using 26656/443 put back.

Results:

• make check-unit, test_dash-qt and rpc_help.py pass.
• The full functional suite passes (319 passed, 15 skipped).
• After the last test and comment tweaks, the evo, ProTx and shares functional tests pass again: rpc_netinfo.py, feature_dip3_deterministicmns.py, feature_protx_version.py, feature_llmq_evo.py, feature_evo_shares_activation.py, feature_masternode_shares.py, feature_masternode_payout_shares.py and wallet_dash_rpcs.py.
• Debug build, Linux x86_64.

Breaking Changes

Once v24 activates on mainnet, version 3 ProRegTx and ProUpServTx transactions must:

• list the masternode's IPv4 address on port 9999 first;
• for an EvoNode, list that same address on 26656 and 443 first in the Platform fields.

On regtest the IPv4 rule now applies by default; tests that need non-IPv4 primaries set -testactivationheight=ipv4_optional@<height>. Testnet and devnets are unchanged.

Walkthrough

The change adds an ipv4_optional consensus deployment and applies address checks according to its activation state. Before activation, provider network validation requires IPv4 primary addresses and matching Platform and Core primary IPs. Mainnet validation also enforces standard ports for primary entries and disallows Platform ports on additional IPv4 entries. The change updates validation entry points, RPC help, release notes, and test coverage.

Estimated code review effort: 4 (Complex) | ~45 minutes

Add a mainnet transaction-level regression for the IPv4-primary rule.

The existing ProRegTx fixture runs on regtest, so an IPv6-first CORE_P2P entry is accepted there. Construct the invalid payload on regtest, select mainnet only for the transaction validator call, and restore regtest afterward. Add the equivalent ProUpServTx case.

The regression must target bad-protx-netinfo-addr-type. Removing the entire CheckProviderNetworkFields call is already detected indirectly by malformed ProRegTx fixtures, but those tests do not cover this specific rule.

Suggested fix

     const NetInfoEntry domain_entry{domain};
     BOOST_REQUIRE(domain_entry.IsTriviallyValid());
     check_reject_reason(DeserializeCoreP2PExtNetInfo({domain_entry}), "bad-protx-netinfo-entry");
+
+    const NetInfoEntry ipv6_entry{LookupNumeric("2606:4700:4700::1111", port)};
+    BOOST_REQUIRE(ipv6_entry.IsTriviallyValid());
+    SelectParams(CBaseChainParams::MAIN);
+    check_reject_reason(DeserializeCoreP2PExtNetInfo({ipv6_entry}), "bad-protx-netinfo-addr-type");
+    SelectParams(CBaseChainParams::REGTEST);

In the existing FuncEvoNodeRaisedToExtAddrByServiceUpdateOnly fixture:

     BOOST_CHECK_EQUAL(check_proupserv(CreateEvoProUpServTx(setup, proTxHash, ProTxVersion::BasicBLS, "1.1.1.4", operator_key)),
                       "bad-protx-version-disallowed");
+
+    const auto invalid_core_tx = CreateEvoProUpServTx(
+        setup, proTxHash, ProTxVersion::ExtAddr, "[2606:4700:4700::1111]", operator_key);
+    SelectParams(CBaseChainParams::MAIN);
+    BOOST_CHECK_EQUAL(check_proupserv(invalid_core_tx), "bad-protx-netinfo-addr-type");

Thanks. I'm leaving this one out. CheckProRegTx and CheckProUpServTx both reach the rule only through CheckProviderNetworkFields, and this PR leaves that wiring as it is. extnetinfo_ipv4_primary_mainnet_only already calls CheckProviderNetworkFields on a deserialized, IPv6-first object under mainnet params and checks for bad-protx-netinfo-addr-type; the mutation check showed it fails without the Validate() rule. Switching to mainnet params partway through a regtest chain fixture would also put every other mainnet-dependent check in those validators against a regtest chain, which makes the test fragile without covering more of this change.

Final validation — Phase 1 + Phase 2

Static verification of exact head 6b25a89 found no actionable issues: the mainnet-only IPv4-primary rule is enforced during construction and independently on deserialized provider transaction data, with focused regression coverage. Existing version gating protects historical mainnet validation, provided the change ships before mainnet v24 activation as documented. Current CI reports passing Linux tests, completed platform builds, lint, formatting, and Cppcheck; the multiprocess build and ASan, TSan, and SQLite tests remain pending, and no local builds or tests were run.

Add a mainnet test for Platform-before-Core insertion.

313-314: Trivial · Maintainability & Code Quality · Quick win

Add a mainnet test for Platform-before-Core insertion.

On mainnet, AddEntry(PLATFORM_P2P, "1.1.1.1:26656") followed by AddEntry(CORE_P2P, "1.1.2.2:9999") returns Success for both calls. Validate() then returns BadAddress, because the Platform primary no longer matches the Core primary. The existing mainnet cases insert Core entries first, so this order is not covered. Add a case in extnetinfo_primary_rules_mainnet_only that asserts the two AddEntry results and the Validate() result. This pins the current deferred rejection. If the intended contract is that AddEntry() rejects a Platform primary before a Core entry exists, change the expected results in that case.

Suggested test addition

-    SelectParams(CBaseChainParams::TESTNET);
+    // Platform primary inserted before any Core entry: AddEntry() accepts it, Validate() rejects the mismatch
+    SelectParams(CBaseChainParams::MAIN);
+    {

+        BOOST_CHECK_EQUAL(net_info.AddEntry(NetInfoPurpose::PLATFORM_P2P, "1.1.1.1:26656"), NetInfoStatus::Success);

Thanks. That ordering is intentional. AddEntry() only checks a Platform entry against the Core address once a Core entry exists, so Platform entries submitted without one get bad-protx-netinfo-empty instead of a misleading address error. Every builder in the tree (ApplyNetInfo, the state-version migration, the GUI) adds Core entries first. Consensus doesn't depend on insertion order: Validate() rejects a Platform address that differs from the Core address, which the BadAddress case in extnetinfo_primary_rules_mainnet_only already covers. I'd rather not add a test that pins the intermediate result of an order no caller uses.

Re-review — Final validation — Phase 1 + Phase 2

Verified the complete diff at e97a2ae and found no blocking correctness or consensus-safety defects; the release-note filename does violate the documented repository convention. Validation covers both constructed and deserialized network information, and the supplied base-drift evidence reports no merge conflicts. This was a static review: current CI reports no failures, with the ASan and multiprocess test jobs still pending and the other listed build, test, and lint checks passing.

  The release-notes section of doc/developer-notes.md specifies PR-specific filenames in the form doc/release-notes-<PR number>.md. Rename this file to doc/release-notes-8018.md so it follows that convention and is directly attributable to this PR. No content change is needed. The documented merge process includes all release-notes* files, so this is a naming-convention issue, not evidence that the note will be omitted from the release.

Re-review — Final validation — Phase 1 + Phase 2

Independently reviewed the complete diff at b3c9ed0 and found no actionable issues: construction and consensus validation share the mainnet restrictions, with compatible migration paths and preserved non-mainnet behavior. The prior release-note naming finding is fixed, and the supplied base-drift evidence shows no conflicts or overlapping changes. Validation was static only; current CI shows the Linux build, lint, cppcheck, and formatting checks passing, while source tests and other build configurations remain pending.

Re-review — Final validation — Phase 1 + Phase 2

Verified both reviewer lanes against exact head 778802f and reproduced a clean textual merge with develop tip aed8d44 that retains an incompatible ValidateNetInfo caller, creating a compile blocker. The new deployment is also missing from RPC deployment reporting; the prior release-note naming issue is fixed. This was a static review with no local builds or tests: current CI reports passing standard, SQLite, no-wallet and ASan tests plus ClangFormat, while TSan tests and the multiprocess build remain pending.

This PR adds DEPLOYMENT_IPV4_OPTIONAL, its deployment name and its configurable activation height, but DeploymentInfo() still explicitly enumerates buried deployments only through DEPLOYMENT_WITHDRAWALS. Consequently, getdeploymentinfo.deployments and the deprecated getblockchaininfo.softforks omit ipv4_optional even on testnet/devnet or when a finite activation height is configured on regtest. Add it to this existing enumeration so operators can inspect the activation state. SoftForkDescPushBack() already filters disabled deployments, so mainnet's unscheduled INT_MAX placeholder will remain hidden.

  Develop tip aed8d442b7 adds FindNetInfoInUse() through #8034, whose validation call still uses ValidateNetInfo(net_info, type, version, /*optional=*/true). Merging this exact head with that base succeeds without textual conflicts, but the resulting tree retains that four-argument call alongside only the new five-argument declaration and definition requiring NodeContext. The merged source therefore cannot compile. Incorporate the base change and pass node as the first argument from FindNetInfoInUse().

Fixed in af02457. I rebased onto develop 44f9f78, and FindNetInfoInUse() now passes node to ValidateNetInfo(), so its validity check uses the same activation as the rest of the pre-checks. git range-diff shows commit 1 unchanged, and commit 2 differs only by that caller and shifted context. The full unit suite, test_dash-qt and the evo/ProTx functional tests pass on the rebased tree.

Resolved (re-reviewed at af024575): Confirmed your rebase fix: FindNetInfoInUse() now passes node to ValidateNetInfo() at src/evo/providertx_service.cpp:839, matching the updated declaration and definition. The node-interface caller also passes its context, and no old four-argument callers remain.

Re-review — Final validation — Phase 1 + Phase 2

Reviewed the complete diff at af02457: no blocking defects were confirmed, but the new deployment remains absent from RPC deployment reporting. The caller-signature and release-note naming findings are fixed; the supplied base drift affects separate Qt dissolution tests and does not supersede this change. This was a static review: current CI shows lint, Cppcheck and several builds passing, while ClangFormat, additional builds and test jobs remain pending.

🟡 Suggestion: Include the new buried deployment in RPC deployment reporting
src/rpc/blockchain.cpp:1683

DEPLOYMENT_IPV4_OPTIONAL now has name lookup, network-specific activation heights, a regtest override and consensus consumers, but DeploymentInfo() still enumerates buried deployments only through DEPLOYMENT_WITHDRAWALS. Consequently, getdeploymentinfo and the deprecated getblockchaininfo.softforks object omit ipv4_optional on testnet/devnet, where it is active, and on regtest when an activation height is configured. Add it to this enumeration so callers can discover its activation state and height. SoftForkDescPushBack() already filters through DeploymentEnabled(), so deployments configured at INT_MAX will remain omitted on mainnet and default regtest. An assertion in rpc_netinfo.py alongside its activation override would cover this reporting path.

Updated to f41b8eb. Changes since 778802f, the head kwvg approved:

• Rebased onto develop. The new FindNetInfoInUse() caller now passes node to ValidateNetInfo().
• Removed the ban on additional IPv4 entries using 26656/443 on mainnet. The draft spec only pins the first entry of each purpose (9999/26656/443 on mainnet). Additional entries now follow only the general port rules, which are unchanged, so a second IPv4 address can serve Core on 9999 and Platform on 26656/443. The first-entry pins and the IPv4/same-address rule are unchanged.
• Tests:
  • new unit rows accept additional addresses on the standard ports;
  • rpc_netinfo.py now also checks that generateblock rejects the rule-breaking ProTxs below the activation height;
  • the full unit, Qt and functional suites pass.
• Note on IPv4OptionalHeight for the eventual EHF deployment. Testnet and devnets must stay always active. The no-chain DeploymentActiveAfter(nullptr, ...) use in ValidateNetInfo() and its test needs adapting. The mainnet first-entry port pins don't depend on the activation, so an I2P first entry (port 0) stays invalid on mainnet.

On the suggestion to list ipv4_optional in getdeploymentinfo: it's left out on purpose for now. It's a placeholder, and the real deployment will be an EHF deployment of a different type. Reporting it now would put a buried entry in the RPC output that later changes shape. It can be listed once the actual deployment is defined.

Reviewed the complete diff at f41b8eb and found no actionable in-scope defects. The caller-signature and release-note findings are fixed; the deployment-reporting suggestion is withdrawn because withholding the provisional RPC entry is a valid compatibility choice. This was a static review with no builds or tests executed locally: current CI shows Lint, Cppcheck and five source builds passing, while five source builds, source-test jobs and ClangFormat remain pending.

Updated to 428293c, changing only the second commit. The GUI's endpoint checks no longer take cs_main:

• The problem: at f41b8eb, validateProviderNetInfo() looked up the activation state itself, and doing so took cs_main. The Update Service dialog calls it on every keystroke, so typing could stall during initial sync or reindex.
• The fix: ProviderTxCapabilities now carries ipv4_optional, read under the same lock as the provider version. validateProviderNetInfo() and findProviderNetInfoInUse() take the flag from the caller's snapshot, and the wizard's Platform page pins it along with the version. Submission still rechecks against the active rules.
• No-chain path removed: ValidateNetInfo() no longer takes the node, so its no-chain fallback is gone. Every production caller now evaluates the placeholder through the chainman overloads, which an EHF deployment can also use.
• Tests:
  • capabilities report the flag (false on default regtest, true when activated);
  • validation completes while another thread holds cs_main, at the interface level and when typing in the Update Service dialog;
  • the dialog follows its snapshot's flag;
  • no-chain unit coverage includes the relaxed flag.
