Peers already store per-interface MAC addresses in meta_network_addresses, but they were neither returned by the peers API nor searchable.

Add a network_addresses field (net_ip + mac) to the Peer/PeerBatch responses and a dedicated mac query parameter on GET /api/peers that matches the MAC JSON column, enabling GET /api/peers?mac=<mac> and dashboard search by MAC.

Describe your changes

Peers collect their per-interface MAC addresses (stored in the meta_network_addresses column), but they were never returned by the peers API nor usable for filtering. This exposes them and lets peers be searched by MAC.

  • API response: added a network_addresses field (array of { net_ip, mac })
    to the Peer schema, returned on both GET /api/peers (PeerBatch) and
    GET /api/peers/{id}.
  • New filter: added a mac query parameter to GET /api/peers, alongside
    the existing name / ip parameters. It does a server-side substring match
    against the stored network addresses, e.g. GET /api/peers?mac=00:93:37.
  • Threaded macFilter through AccountManager.GetPeers and
    Store.GetAccountPeers, regenerated the OpenAPI types, and updated the mocks.
  • Added a store test (TestSqlStore_GetAccountPeers_FilterByMac) covering full
    MAC, prefix, and no-match cases.

Example response entry:

"network_addresses": [
  { "net_ip": "192.168.0.11/24", "mac": "00:93:37:bd:83:0f" }
]

📝 Walkthrough

Walkthrough

The PR adds MAC-based peer filtering across the store, manager, and HTTP handlers. It adds network_addresses to peer API models and updates peer-retrieval call sites and tests for the expanded signatures.

Changes

Peer MAC filtering and network addresses

Layer / File(s) Summary
API contract and models
shared/management/http/api/openapi.yml, shared/management/http/api/types.gen.go
Adds NetworkAddress, extends Peer and PeerBatch with network_addresses, and adds the mac query parameter to GET /api/peers.
Store MAC filtering
management/server/store/store.go, management/server/store/store_mock.go, management/server/store/sql_store.go, management/server/store/sql_store_test.go
GetAccountPeers accepts macFilter. The SQL query matches MAC values in meta_network_addresses. Tests cover exact, prefix, and unknown MAC filters.
Manager plumbing
management/server/account/manager.go, management/server/peer.go, management/server/account/manager_mock.go, management/server/mock_server/account_mock.go, management/server/peer_test.go
GetPeers accepts and forwards macFilter. Mocks and manager tests use the updated signature.
HTTP handlers and peer responses
management/server/http/handlers/peers/peers_handler.go, management/server/http/handlers/accounts/accounts_handler.go, management/server/http/handlers/groups/*
The peers handler reads mac and maps network addresses into peer responses. Account and group handlers use the expanded filter list.
Server call sites and tests
management/internals/..., management/server/account.go, management/server/integrated_validator.go, management/server/account_test.go
Account peer lookups pass the expanded filter list. Related tests use the updated store call signature.

Apply filters after permission scoping.

When allowed is false, this falls back to GetUserPeers(...) and drops nameFilter, ipFilter, and the new macFilter. That makes GET /api/peers?mac=... return an unfiltered peer list for regular users instead of filtering the peers they are allowed to see. Either filter the GetUserPeers result in-memory or add a filter-aware restricted query path.

🎯 Functional Correctness | 🟠 Major

Restrict the mac filter to NetworkAddress.Mac values.

The meta_network_addresses LIKE ? clause performs a text search on the raw JSON string. This causes false positives by matching NetIP values, key names (e.g., "Mac"), or random substrings, returning peers whose MAC addresses do not match the filter.

🔧 Suggested fix

Perform MAC filtering in Go after retrieving peers to ensure precise matching on the Mac field.

Constrain mac to MAC-safe characters.

GetAccountPeers() now feeds this value into LIKE "%<macFilter>%" against meta_network_addresses, so % and _ behave as wildcards. A request like ?mac=% will match unrelated peers instead of a MAC substring. Add input validation here and escape LIKE wildcards server-side before querying.

Whtas a use case for that?

Hi,

Currently a fleet of IoT devices we want to manage are registered in our own database and internal tools using their mac addresses.

Our OTA system actually allows to query and select devices through their MAC addresses.

So for us, Netbird is lacking this feature as of today, and this change was made to fill this gap.

One thing to note, the mac addresses were already stored in Netbird's database, but they weren't exposed.

Hi @a-elkaim, I just reviewed the PR. Sorry for the late response. The PR is fine and I would be able to approve. Can you merge main into your PR so we are able to merge this?

Peers already store per-interface MAC addresses in meta_network_addresses,
but they were neither returned by the peers API nor searchable. Add a
network_addresses field (net_ip + mac) to the Peer/PeerBatch responses and a
dedicated `mac` query parameter on GET /api/peers that matches the MAC JSON
column, enabling `GET /api/peers?mac=<mac>` and dashboard search by MAC.

Apply macFilter to the regular-user path.

When ValidateUserPermissions returns false and RegularUsersViewBlocked is false, DefaultAccountManager.GetPeers calls Store.GetUserPeers without a filter. SqlStore.GetUserPeers returns every peer owned by the user, so a nonmatching mac value still returns those peers. Extend the user-scoped query to apply macFilter and add a regular-user no-match test.

Hi @a-elkaim, I triggered the CI tests. You will need to run the shared/management/http/api/generate.sh to generate new openapi types for release check to pass. And you will need to add some unit tests to cover this path

The generated peer query types were missing the mac parameter, and
MAC filtering needed coverage beyond the basic store test.

Run the OpenAPI generator and test MAC filtering through the HTTP
handler, account manager, and SQL store. Cover partial matches,
multiple interfaces, combined filters, and account isolation.
Verify network address serialization and omission in peer responses.

Validation: focused tests pass; lint reports zero issues.

3530-3534: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The MAC filter is appended directly to a SQL LIKE pattern, so % and _ in ?mac= act as wildcards rather than literal substring characters. For example, mac=% returns every peer in the account with a non-null address payload instead of peers containing a percent sign. Escape LIKE metacharacters (with an explicit ESCAPE clause) before constructing this predicate.
