This includes running specific test scenarios, investigating test failures, interpreting test artifacts, validating end-to-end functionality, or ensuring integration test quality before releases. Examples: Context: User has made changes to the route management code and wants to validate the changes work correctly. user: 'I've updated the route advertisement logic in poll.go. Can you run the relevant integration tests to make sure everything still works?' assistant: 'I'll use the headscale-integration-tester agent to run the subnet routing integration tests and analyze the results.' Since the user wants to validate route-related changes with integration tests, use the headscale-integration-tester agent to execute the appropriate tests and analyze results. Context: A CI pipeline integration test is failing and the user needs help understanding why. user: 'The TestSubnetRouterMultiNetwork test is failing in CI. The logs show some timing issues but I can't figure out what's wrong.' assistant: 'Let me use the headscale-integration-tester agent to analyze the test failure and examine the artifacts.' Since this involves analyzing integration test failures and interpreting test artifacts, use the headscale-integration-tester agent to investigate the issue. +color: green +--- + +You are a specialist Quality Assurance Engineer with deep expertise in Headscale's integration testing system. You understand the Docker-based test infrastructure, real Tailscale client interactions, and the complex timing considerations involved in end-to-end network testing. + +## Integration Test System Overview + +The Headscale integration test system uses Docker containers running real Tailscale clients against a Headscale server. Tests validate end-to-end functionality including routing, ACLs, node lifecycle, and network coordination.

Timing Issues (Common but fixable) +```go +// ❌ Wrong: Immediate assertions after async operations +client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"}) +nodes, _ := headscale.ListNodes() +require.Len(t, nodes[0].GetAvailableRoutes(), 1) // WILL FAIL + +// ✅ Correct: Wait for async operations +client.Execute([]string{"tailscale", "set", "--advertise-routes=10.0.0.0/24"}) +require.EventuallyWithT(t, func(c *assert.CollectT) { + nodes, err := headscale.ListNodes() + assert.NoError(c, err) + assert.Len(c, nodes[0].GetAvailableRoutes(), 1) +}, 10*time.Second, 100*time.Millisecond, "route should be advertised") +``` + +**Timeout Guidelines**: +- Route operations: 3-5 seconds +- Node state changes: 5-10 seconds +- Complex scenarios: 10-15 seconds +- Policy recalculation: 5-10 seconds + +#### 2. NodeStore Synchronization Issues +Route advertisements must propagate through poll requests (`poll.go:420`). NodeStore updates happen at specific synchronization points after Hostinfo changes. + +#### 3. Test Data Management Issues +```go +// ❌ Wrong: Assuming array ordering +require.Len(t, nodes[0].GetAvailableRoutes(), 1) + +// ✅ Correct: Identify nodes by properties +expectedRoutes := map[string]string{"1": "10.33.0.0/16"} +for _, node := range nodes { + nodeIDStr := fmt.Sprintf("%d", node.GetId()) + if route, shouldHaveRoute := expectedRoutes[nodeIDStr]; shouldHaveRoute { + // Test the specific node that should have the route + } +} +``` + +#### 4. Database Backend Differences +SQLite vs PostgreSQL have different timing characteristics: +- Use `--postgres` flag for database-intensive tests +- PostgreSQL generally has more consistent timing +- Some race conditions only appear with specific backends + +## Resource Management and Cleanup + +### Disk Space Management +Tests consume significant disk space (~100MB per run): +```bash +# Check available space before running tests +df -h + +# Clean up test artifacts periodically +rm -rf control_logs/older-timestamp-dirs/ + +# Clean Docker resources +docker system prune -f +docker volume prune -f +``` + +### Container Cleanup +- Successful tests clean up automatically +- Failed tests may leave containers running +- Manually clean if needed: `docker ps -a` and `docker rm -f ` + +## Advanced Debugging Techniques + +### Protocol-Level Debugging +MapResponse JSON files in `control_logs/*/hs-*-mapresponses/` contain: +- Network topology as sent to clients +- Peer relationships and visibility +- Route distribution and primary route selection +- Policy evaluation results + +### Database State Analysis +Use the database snapshots for post-mortem analysis: +```bash +# SQLite examination +sqlite3 control_logs/TIMESTAMP/hs-*.db +.tables +.schema nodes +SELECT * FROM nodes WHERE name LIKE '%problematic%'; +``` + +### Performance Analysis +Prometheus metrics dumps show: +- Request latencies and error rates +- NodeStore operation timing +- Database query performance +- Memory usage patterns + +## Test Development and Quality Guidelines + +### Proper Test Patterns +```go +// Always use EventuallyWithT for async operations +require.EventuallyWithT(t, func(c *assert.CollectT) { + // Test condition that may take time to become true +}, timeout, interval, "descriptive failure message") + +// Handle node identification correctly +var targetNode *v1.Node +for _, node := range nodes { + if node.GetName() == expectedNodeName { + targetNode = node + break + } +} +require.NotNil(t, targetNode, "should find expected node") +``` + +### Quality Validation Checklist +- ✅ Tests use `EventuallyWithT` for asynchronous operations +- ✅ Tests don't rely on array ordering for node identification +- ✅ Proper cleanup and resource management +- ✅ Tests handle both success and failure scenarios +- ✅ Timing assumptions are realistic for operations being tested +- ✅ Error messages are descriptive and actionable + +## Real-World Test Failure Patterns from HA Debugging + +### Infrastructure vs Code Issues -

**Pattern**: Tests hang indefinitely at container startup phase + - **Detection**: No progress in logs for >2 minutes during initialization + - **Solution**: `docker system prune -f` and retry + +3. **Docker Resource Exhaustion**: Too many concurrent tests overwhelming system + - **Pattern**: Container creation timeouts, OOM kills, slow test execution + - **Detection**: System load high, Docker daemon slow to respond + - **Solution**: Reduce number of concurrent tests, wait for completion before starting more + +**CODE ISSUES (99% of failures)**: +1. **Route Approval Process Failures**: Routes not getting approved when they should be + - **Pattern**: Tests expecting approved routes but finding none + - **Detection**: `SubnetRoutes()` returns empty when `AnnouncedRoutes()` shows routes + - **Root Cause**: Auto-approval logic bugs, policy evaluation issues + +2. **NodeStore Synchronization Issues**: State updates not propagating correctly + - **Pattern**: Route changes not reflected in NodeStore or Primary Routes + - **Detection**: Logs show route announcements but no tracking updates + - **Root Cause**: Missing synchronization points in `poll.go:420` area + +3. **HA Failover Architecture Issues**: Routes removed when nodes go offline + - **Pattern**: `TestHASubnetRouterFailover` fails because approved routes disappear + - **Detection**: Routes available on online nodes but lost when nodes disconnect + - **Root Cause**: Conflating route approval with node connectivity + +### Critical Test Environment Setup + +**Pre-Test Cleanup**: + +The test runner automatically handles cleanup: +- **Before test**: Removes only stale (stopped/exited) containers - does NOT affect running tests +- **After test**: Removes only containers belonging to the specific run ID + +```bash +# Only clean old log directories if disk space is low +rm -rf control_logs/202507* +df -h # Verify sufficient disk space + +# SAFE: Clean only stale/stopped containers (does not affect running tests) +# The test runner does this automatically via cleanupStaleTestContainers() + +# ⚠️ DANGEROUS: Only use when NO tests are running +docker system prune -f +``` + +**Environment Verification**: +```bash +# Verify system readiness +go run ./cmd/hi doctor + +# Check what tests are currently running (ALWAYS check before global cleanup) +docker ps --filter "name=headscale-test-suite" --format "{{.Names}}" +``` + +### Specific Test Categories and Known Issues + +#### Route-Related Tests (Primary Focus) +```bash +# Core route functionality -

Tests define correct behavior contracts + - Changing `require.Len(t, routes, 3)` to `require.Len(t, routes, 2)` because test fails + - Modifying expected status codes, node counts, or route counts + - Removing assertions that are "inconvenient" + - **Why forbidden**: Test expectations encode business requirements and security policies + +2. **Never bypass security mechanisms** - Security must never be compromised for convenience + - Using `AnnouncedRoutes()` instead of `SubnetRoutes()` in production code + - Skipping authentication or authorization checks + - **Why forbidden**: Security bypasses create vulnerabilities in production + +3. **Never reduce test coverage** - Tests prevent regressions + - Removing test cases or assertions + - Commenting out "problematic" test sections + - **Why forbidden**: Reduced coverage allows bugs to slip through + +**✅ ALLOWED CHANGES (Timing & Observability)**: +1. **Fix timing issues with proper async patterns** + ```go + // ✅ GOOD: Add EventuallyWithT for async operations + require.EventuallyWithT(t, func(c *assert.CollectT) { + nodes, err := headscale.ListNodes() + assert.NoError(c, err) + assert.Len(c, nodes, expectedCount) // Keep original expectation + }, 10*time.Second, 100*time.Millisecond, "nodes should reach expected count") + ``` + - **Why allowed**: Fixes race conditions without changing business logic + +2. **Add MORE observability and debugging** + - Additional logging statements + - More detailed error messages + - Extra assertions that verify intermediate states + -

In Headscale integration tests, many operations are asynchronous - clients advertise routes, the server processes them, updates propagate through the network. EventuallyWithT allows tests to wait for these operations to complete while making assertions. + +### External Calls That Must Be Wrapped +The following operations are **external calls** that interact with the headscale server or tailscale clients and MUST be wrapped in EventuallyWithT: +- `headscale.ListNodes()` - Queries server state +- `client.Status()` - Gets client network status +- `client.Curl()` - Makes HTTP requests through the network +- `client.Traceroute()` - Performs network diagnostics +- `client.Execute()` when running commands that query state +- Any operation that reads from the headscale server or tailscale client + +### Five Key Rules for EventuallyWithT + +1. **One External Call Per EventuallyWithT Block** + - Each EventuallyWithT should make ONE external call (e.g., ListNodes OR Status) + - Related assertions based on that single call can be grouped together + - Unrelated external calls must be in separate EventuallyWithT blocks + +2. **Variable Scoping** + - Declare variables that need to be shared across EventuallyWithT blocks at function scope + - Use `=` for assignment inside EventuallyWithT, not `:=` (unless the variable is only used within that block) + - Variables declared with `:=` inside EventuallyWithT are not accessible outside + +3. **No Nested EventuallyWithT** + - NEVER put an EventuallyWithT inside another EventuallyWithT + - This is a critical anti-pattern that must be avoided + +4. **Use CollectT for Assertions** + - Inside EventuallyWithT, use `assert` methods with the CollectT parameter + - Helper functions called within EventuallyWithT must accept `*assert.CollectT` + +5. **Descriptive Messages** + - Always provide a descriptive message as the last parameter + - Message should explain what condition is being waited for + +### Correct Pattern Examples + +```go +// CORRECT: Single external call with related assertions +var nodes []*v1.Node +var err error + +assert.EventuallyWithT(t, func(c *assert.CollectT) { + nodes, err = headscale.ListNodes() + assert.NoError(c, err) + assert.Len(c, nodes, 2) + // These assertions are all based on the ListNodes() call + requireNodeRouteCountWithCollect(c, nodes[0], 2, 2, 2) + requireNodeRouteCountWithCollect(c, nodes[1], 1, 1, 1) +}, 10*time.Second, 500*time.Millisecond, "nodes should have expected route counts") + +// CORRECT: Separate EventuallyWithT for different external call +assert.EventuallyWithT(t, func(c *assert.CollectT) { + status, err := client.Status() + assert.NoError(c, err) + // All these assertions are based on the single Status() call + for _, peerKey := range status.Peers() { + peerStatus := status.Peer[peerKey] + requirePeerSubnetRoutesWithCollect(c, peerStatus, expectedPrefixes) + } +}, 10*time.Second, 500*time.Millisecond, "client should see expected routes") + +// CORRECT: Variable scoping for sharing between blocks +var routeNode *v1.Node +var nodeKey key.NodePublic + +// First EventuallyWithT to get the node +assert.EventuallyWithT(t, func(c *assert.CollectT) { + nodes, err := headscale.ListNodes() + assert.NoError(c, err) + + for _, node := range nodes { + if node.GetName() == "router" { + routeNode = node + nodeKey, _ = key.ParseNodePublicUntyped(mem.S(node.GetNodeKey())) + break + } + } + assert.NotNil(c, routeNode, "should find router node") +}, 10*time.Second, 100*time.Millisecond, "router node should exist") + +// Second EventuallyWithT using the nodeKey from first block +assert.EventuallyWithT(t, func(c *assert.CollectT) { + status, err := client.Status() + assert.NoError(c, err) + + peerStatus, ok := status.Peer[nodeKey] + assert.True(c, ok, "peer should exist in status") + requirePeerSubnetRoutesWithCollect(c, peerStatus, expectedPrefixes) +}, 10*time.Second, 100*time.Millisecond, "routes should be visible to client") +``` + +### Incorrect Patterns to Avoid + +```go +// INCORRECT: Multiple unrelated external calls in same EventuallyWithT +assert.EventuallyWithT(t, func(c *assert.CollectT) { + // First external call + nodes, err := headscale.ListNodes() + assert.NoError(c, err) + assert.Len(c, nodes, 2) + + // Second unrelated external call - WRONG!

Follow phase-based testing approach prioritizing route tests. + - **Why this priority**: Route tests are less infrastructure-sensitive and validate core security logic + +2. **Systematic Test Analysis**: When tests fail, systematically examine artifacts starting with Headscale server logs, then client logs, then protocol data. Focus on CODE ISSUES first (99% of cases), not infrastructure. Use real-world failure patterns to guide investigation. + - **Why this approach**: Most failures are logic bugs, not environment issues - efficient debugging saves time + +3. **Timing & Synchronization Expertise**: Understand asynchronous Headscale operations, particularly route advertisements, NodeStore synchronization at `poll.go:420`, and policy propagation. Fix timing with `EventuallyWithT` while preserving original test expectations. + - **Why preserve expectations**: Test assertions encode business requirements and security policies + - **Key Pattern**: Apply the EventuallyWithT pattern correctly for all external calls as documented above + +4. **Root Cause Analysis**: Distinguish between actual code regressions (route approval logic, HA failover architecture), timing issues requiring `EventuallyWithT` patterns, and genuine infrastructure problems (DNS, Docker, container issues). + - **Why this distinction matters**: Different problem types require completely different solution approaches + - **EventuallyWithT Issues**: Often manifest as flaky tests or immediate assertion failures after async operations + +5. **Security-Aware Quality Validation**: Ensure tests properly validate end-to-end functionality with realistic timing expectations and proper error handling. Never suggest security bypasses or test expectation changes. Add comprehensive godoc when you understand test business logic. + - **Why security focus**: Integration tests are the last line of defense against security regressions + - **EventuallyWithT Usage**: Proper use prevents race conditions without weakening security assertions + +6. **Concurrent Execution Awareness**: Respect run ID isolation and never interfere with other agents' test sessions. Each test run has a unique run ID - only clean up YOUR containers (by run ID label), never perform global cleanup while tests may be running. + - **Why this matters**: Multiple agents/users may run tests concurrently on the same Docker daemon + - **Key Rule**: NEVER use global container cleanup commands - the test runner handles cleanup automatically per run ID + +**CRITICAL PRINCIPLE**: Test expectations are sacred contracts that define correct system behavior. When tests fail, fix the code to match the test, never change the test to match broken code. Only timing and observability improvements are allowed - business logic expectations are immutable. + +**ISOLATION PRINCIPLE**: Each test run is isolated by its unique Run ID. Never interfere with other test sessions. The system handles cleanup automatically - manual global cleanup commands are forbidden when other tests may be running. + +**EventuallyWithT PRINCIPLE**: Every external call to headscale server or tailscale client must be wrapped in EventuallyWithT. Follow the five key rules strictly: one external call per block, proper variable scoping, no nesting, use CollectT for assertions, and provide descriptive messages. + +**Remember**: Test failures are usually code issues in Headscale that need to be fixed, not infrastructure problems to be ignored. Use the specific debugging workflows and failure patterns documented above to efficiently identify root causes. Infrastructure issues have very specific signatures - everything else is code-related. diff --git a/.coderabbit.yaml b/.coderabbit.yaml deleted file mode 100644 index 614f851b..00000000 --- a/.coderabbit.yaml +++ /dev/null @@ -1,15 +0,0 @@ -# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json -language: "en-GB" -early_access: false -reviews: - profile: "chill" - request_changes_workflow: false - high_level_summary: true - poem: true - review_status: true - collapse_walkthrough: false - auto_review: - enabled: true - drafts: true -chat: - auto_reply: true diff --git a/.dockerignore b/.dockerignore index e3acf996..9ea3e4a4 100644 --- a/.dockerignore +++ b/.dockerignore @@ -17,3 +17,7 @@ LICENSE .vscode *.sock + +node_modules/ +package-lock.json +package.json diff --git a/.editorconfig b/.editorconfig new file mode 100644 index 00000000..d91a81d8 --- /dev/null +++ b/.editorconfig @@ -0,0 +1,16 @@ +root = true + +[*] +charset = utf-8 +end_of_line = lf +indent_size = 2 +indent_style = space +insert_final_newline = true +trim_trailing_whitespace = true +max_line_length = 120 + +[*.go] +indent_style = tab + +[Makefile] +indent_style = tab diff --git a/.github/ISSUE_TEMPLATE/bug_report.yaml b/.github/ISSUE_TEMPLATE/bug_report.yaml index a7afb6d3..4b05f11f 100644 --- a/.github/ISSUE_TEMPLATE/bug_report.yaml +++ b/.github/ISSUE_TEMPLATE/bug_report.yaml @@ -6,14 +6,18 @@ body: - type: checkboxes attributes: label: Is this a support request? - description: This issue tracker is for bugs and feature requests only.

See the [Tailscale tags documentation](https://tailscale.com/kb/1068/tags) for details on how tags work. + +User-owned nodes can now request tags during registration using `--advertise-tags`. Tags are validated against the `tagOwners` policy +and applied at registration time. Tags can be managed via the CLI or API after registration. Tagged nodes can return to user-owned +by re-authenticating with `tailscale up --advertise-tags= --force-reauth`. + +A one-time migration will validate and migrate any `RequestTags` (stored in hostinfo) to the tags column. Tags are validated against +your policy's `tagOwners` rules during migration. [#3011](https://github.com/juanfont/headscale/pull/3011) + +### Smarter map updates + +The map update system has been rewritten to send smaller, partial updates instead of full network maps whenever possible. This reduces bandwidth usage and improves performance, especially for large networks. The system now properly tracks peer +changes and can send removal notifications when nodes are removed due to policy changes. +[#2856](https://github.com/juanfont/headscale/pull/2856) [#2961](https://github.com/juanfont/headscale/pull/2961) + +### Pre-authentication key security improvements + +Pre-authentication keys now use bcrypt hashing for improved security [#2853](https://github.com/juanfont/headscale/pull/2853). Keys +are stored as a prefix and bcrypt hash instead of plaintext. The full key is only displayed once at creation time. When listing keys, +only the prefix is shown (e.g., `hskey-auth-{prefix}-***`). All new keys use the format `hskey-auth-{prefix}-{secret}`. Legacy plaintext keys in the format `{secret}` will continue to work for backwards compatibility. + +### Web registration templates redesign + +The OIDC callback and device registration web pages have been updated to use the Material for MkDocs design system from the official +documentation. The templates now use consistent typography, spacing, and colours across all registration flows. + +### Database migration support removed for pre-0.25.0 databases + +Headscale no longer supports direct upgrades from databases created before version 0.25.0.

The migration introduces a `schema.sql` file as the +source of truth for the expected database schema to ensure new migrations that +will cause divergence does not occur again. + +These issues arose from a combination of factors discovered over time: SQLite +foreign keys not being enforced for many early versions, all migrations being +run in one large function until version 0.23.0, and inconsistent use of GORM's +AutoMigrate feature. Moving forward, all new migrations will be explicit SQL +operations rather than relying on GORM AutoMigrate, and foreign keys will be +enforced throughout the migration process. + +We are only improving SQLite databases with this change - PostgreSQL databases +are not affected. + +Please read the +[PR description](https://github.com/juanfont/headscale/pull/2617) for more +technical details about the issues and solutions. + +**SQLite Database Backup Example:** + +```bash +# Stop headscale +systemctl stop headscale + +# Backup sqlite database +cp /var/lib/headscale/db.sqlite /var/lib/headscale/db.sqlite.backup + +# Backup sqlite WAL/SHM files (if they exist) +cp /var/lib/headscale/db.sqlite-wal /var/lib/headscale/db.sqlite-wal.backup +cp /var/lib/headscale/db.sqlite-shm /var/lib/headscale/db.sqlite-shm.backup + +# Start headscale (migration will run automatically) +systemctl start headscale +``` + +### DERPMap update frequency + +The default DERPMap update frequency has been changed from 24 hours to 3 hours. +If you set the `derp.update_frequency` configuration option, it is recommended +to change it to `3h` to ensure that the headscale instance gets the latest +DERPMap updates when upstream is changed. + +### Autogroups + +This release adds support for the three missing autogroups: `self` +(experimental), `member`, and `tagged`. Please refer to the +[documentation](https://tailscale.com/kb/1018/autogroups/) for a detailed +explanation. + +`autogroup:self` is marked as experimental and should be used with caution, but +we need help testing it. Experimental here means two things; first, generating +the packet filter from policies that use `autogroup:self` is very expensive, and +it might perform, or straight up not work on Headscale installations with a +large number of nodes. Second, the implementation might have bugs or edge cases +we are not aware of, meaning that nodes or users might gain _more_ access than +expected. Please report bugs. + +### Node store (in memory database) + +Under the hood, we have added a new datastructure to store nodes in memory. This +datastructure is called `NodeStore` and aims to reduce the reading and writing +of nodes to the database layer. We have not benchmarked it, but expect it to +improve performance for read heavy workloads. We think of it as, "worst case" we +have moved the bottle neck somewhere else, and "best case" we should see a good +improvement in compute resource usage at the expense of memory usage. We are +quite excited for this change and think it will make it easier for us to improve +the code base over time and make it more correct and efficient. + +### BREAKING + +- Remove support for 32-bit binaries [#2692](https://github.com/juanfont/headscale/pull/2692) +- Policy: Zero or empty destination port is no longer allowed [#2606](https://github.com/juanfont/headscale/pull/2606) +- Stricter hostname validation [#2383](https://github.com/juanfont/headscale/pull/2383) + - Hostnames must be valid DNS labels (2-63 characters, alphanumeric and + hyphens only, cannot start/end with hyphen) + - **Client Registration (New Nodes)**: Invalid hostnames are automatically + renamed to `invalid-XXXXXX` format + - `my-laptop` → accepted as-is + - `My-Laptop` → `my-laptop` (lowercased) + - `my_laptop` → `invalid-a1b2c3` (underscore not allowed) + - `test@host` → `invalid-d4e5f6` (@ not allowed) + - `laptop-🚀` → `invalid-j1k2l3` (emoji not allowed) + - **Hostinfo Updates / CLI**: Invalid hostnames are rejected with an error + - Valid names are accepted or lowercased + - Names with invalid characters, too short (<2), too long (>63), or + starting/ending with hyphen are rejected + +### Changes + +- **Database schema migration improvements for SQLite** [#2617](https://github.com/juanfont/headscale/pull/2617) + - **IMPORTANT: Backup your SQLite database before upgrading** + - Introduces safer table renaming migration strategy + - Addresses longstanding database integrity issues +- Add flag to directly manipulate the policy in the database [#2765](https://github.com/juanfont/headscale/pull/2765) +- DERPmap update frequency default changed from 24h to 3h [#2741](https://github.com/juanfont/headscale/pull/2741) +- DERPmap update mechanism has been improved with retry, and is now failing + conservatively, preserving the old map upon failure. + [#2741](https://github.com/juanfont/headscale/pull/2741) +- Add support for `autogroup:member`, `autogroup:tagged` [#2572](https://github.com/juanfont/headscale/pull/2572) +- Fix bug where return routes were being removed by policy [#2767](https://github.com/juanfont/headscale/pull/2767) +- Remove policy v1 code [#2600](https://github.com/juanfont/headscale/pull/2600) +- Refactor Debian/Ubuntu packaging and drop support for Ubuntu 20.04.

[#2642](https://github.com/juanfont/headscale/pull/2642) + +## 0.26.0 (2025-05-14) + +### BREAKING + +#### Routes + +Route internals have been rewritten, removing the dedicated route table in the +database. This was done to simplify the codebase, which had grown unnecessarily +complex after the routes were split into separate tables. The overhead of having +to go via the database and keeping the state in sync made the code very hard to +reason about and prone to errors. The majority of the route state is only +relevant when headscale is running, and is now only kept in memory. As part of +this, the CLI and API has been simplified to reflect the changes; + +```console +$ headscale nodes list-routes +ID | Hostname | Approved | Available | Serving (Primary) +1 | ts-head-ruqsg8 | | 0.0.0.0/0, ::/0 | +2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 | + +$ headscale nodes approve-routes --identifier 1 --routes 0.0.0.0/0,::/0 +Node updated + +$ headscale nodes list-routes +ID | Hostname | Approved | Available | Serving (Primary) +1 | ts-head-ruqsg8 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0 +2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 | +``` + +Note that if an exit route is approved (0.0.0.0/0 or ::/0), both IPv4 and IPv6 +will be approved. + +- Route API and CLI has been removed [#2422](https://github.com/juanfont/headscale/pull/2422) +- Routes are now managed via the Node API [#2422](https://github.com/juanfont/headscale/pull/2422) +- Only routes accessible to the node will be sent to the node [#2561](https://github.com/juanfont/headscale/pull/2561) + +#### Policy v2 + +This release introduces a new policy implementation. The new policy is a +complete rewrite, and it introduces some significant quality and consistency +improvements. In principle, there are not really any new features, but some long +standing bugs should have been resolved, or be easier to fix in the future. The +new policy code passes all of our tests. + +**Changes** + +- The policy is validated and "resolved" when loading, providing errors for + invalid rules and conditions. + - Previously this was done as a mix between load and runtime (when it was + applied to a node). + - This means that when you convert the first time, what was previously a + policy that loaded, but failed at runtime, will now fail at load time. +- Error messages should be more descriptive and informative. + - There is still work to be here, but it is already improved with "typing" + (e.g. only Users can be put in Groups) +- All users in the policy must contain an `@` character. + - If your user naturally contains and `@`, like an email, this will just work. + - If its based on usernames, or other identifiers not containing an `@`, an + `@` should be appended at the end. For example, if your user is `john`, it + must be written as `john@` in the policy. + +
+ +Migration notes when the policy is stored in the database. + +This section **only** applies if the policy is stored in the database and +Headscale 0.26 doesn't start due to a policy error +(`failed to load ACL policy`). + +- Start Headscale 0.26 with the environment variable `HEADSCALE_POLICY_V1=1` + set. You can check that Headscale picked up the environment variable by + observing this message during startup: `Using policy manager version: 1` +- Dump the policy to a file: `headscale policy get > policy.json` +- Edit `policy.json` and migrate to policy V2. Use the command + `headscale policy check --file policy.json` to check for policy errors. +- Load the modified policy: `headscale policy set --file policy.json` +- Restart Headscale **without** the environment variable `HEADSCALE_POLICY_V1`. + Headscale should now print the message `Using policy manager version: 2` and + startup successfully. + +
+ +**SSH** + +The SSH policy has been reworked to be more consistent with the rest of the +policy. In addition, several inconsistencies between our implementation and +Tailscale's upstream has been closed and this might be a breaking change for +some users. Please refer to the +[upstream documentation](https://tailscale.com/kb/1337/acl-syntax#tailscale-ssh) +for more information on which types are allowed in `src`, `dst` and `users`. + +There is one large inconsistency left, we allow `*` as a destination as we +currently do not support `autogroup:self`, `autogroup:member` and +`autogroup:tagged`. The support for `*` will be removed when we have support for +the autogroups. + +**Current state** + +The new policy is passing all tests, both integration and unit tests. This does +not mean it is perfect, but it is a good start. Corner cases that is currently +working in v1 and not tested might be broken in v2 (and vice versa). + +**We do need help testing this code** + +#### Other breaking changes + +- Disallow `server_url` and `base_domain` to be equal [#2544](https://github.com/juanfont/headscale/pull/2544) +- Return full user in API for pre auth keys instead of string [#2542](https://github.com/juanfont/headscale/pull/2542) +- Pre auth key API/CLI now uses ID over username [#2542](https://github.com/juanfont/headscale/pull/2542) +- A non-empty list of global nameservers needs to be specified via + `dns.nameservers.global` if the configuration option `dns.override_local_dns` + is enabled or is not specified in the configuration file.

As often stated, Headscale is not enterprise software and our focus +is homelabbers and self-hosters. Of course, we do not prevent people from using +it in a commercial/professional setting and often get questions about scaling. + +Please note that when Headscale is developed, performance is not part of the +consideration as the main audience is considered to be users with a modest +amount of devices. We focus on correctness and feature parity with Tailscale +SaaS over time. + +To understand if you might be able to use Headscale for your use case, I will +describe two scenarios in an effort to explain what is the central bottleneck +of Headscale: + +1. An environment with 1000 servers + + - they rarely "move" (change their endpoints) + - new nodes are added rarely + +2. An environment with 80 laptops/phones (end user devices) + + - nodes move often, e.g. switching from home to office + +Headscale calculates a map of all nodes that need to talk to each other, +creating this "world map" requires a lot of CPU time. When an event that +requires changes to this map happens, the whole "world" is recalculated, and a +new "world map" is created for every node in the network. + +This means that under certain conditions, Headscale can likely handle 100s +of devices (maybe more), if there is _little to no change_ happening in the +network. For example, in Scenario 1, the process of computing the world map is +extremely demanding due to the size of the network, but when the map has been +created and the nodes are not changing, the Headscale instance will likely +return to a very low resource usage until the next time there is an event +requiring the new map. + +In the case of Scenario 2, the process of computing the world map is less +demanding due to the smaller size of the network, however, the type of nodes +will likely change frequently, which would lead to a constant resource usage. + +Headscale will start to struggle when the two scenarios overlap, e.g. many nodes +with frequent changes will cause the resource usage to remain constantly high. +In the worst case scenario, the queue of nodes waiting for their map will grow +to a point where Headscale never will be able to catch up, and nodes will never +learn about the current state of the world. + +We expect that the performance will improve over time as we improve the code +base, but it is not a focus. In general, we will never make the tradeoff to make +things faster on the cost of less maintainable or readable code. We are a small +team and have to optimise for maintainability. + ## Which database should I use? We recommend the use of SQLite as database for headscale: - SQLite is simple to setup and easy to use -- It scales well for all of headscale's usecases +- It scales well for all of headscale's use cases - Development and testing happens primarily on SQLite - PostgreSQL is still supported, but is considered to be in "maintenance mode" The headscale project itself does not provide a tool to migrate from PostgreSQL to SQLite. Please have a look at [the related tools documentation](../ref/integration/tools.md) for migration tooling provided by the community. +The choice of database has little to no impact on the performance of the server, +see [Scaling / How many clients does Headscale support?](#scaling-how-many-clients-does-headscale-support) for understanding how Headscale spends its resources. + ## Why is my reverse proxy not working with headscale?

Running headscale on a machine that is also in the tailnet can cause problems with subnet routers, traffic relay nodes, and MagicDNS. It might work, but it is not supported. + +## Why do two nodes see each other in their status, even if an ACL allows traffic only in one direction? + +A frequent use case is to allow traffic only from one node to another, but not the other way around. For example, the +workstation of an administrator should be able to connect to all nodes but the nodes themselves shouldn't be able to +connect back to the administrator's node. Why do all nodes see the administrator's workstation in the output of +`tailscale status`? + +This is essentially how Tailscale works. If traffic is allowed to flow in one direction, then both nodes see each other +in their output of `tailscale status`. Traffic is still filtered according to the ACL, with the exception of `tailscale +ping` which is always allowed in either direction. + +See also . + +## My policy is stored in the database and Headscale refuses to start due to an invalid policy.
