R.B. Boyer	40336fd353	agent: fix several data races and bugs related to node-local alias checks (#5876 ) The observed bug was that a full restart of a consul datacenter (servers and clients) in conjunction with a restart of a connect-flavored application with bring-your-own-service-registration logic would very frequently cause the envoy sidecar service check to never reflect the aliased service. Over the course of investigation several bugs and unfortunate interactions were corrected: (1) local.CheckState objects were only shallow copied, but the key piece of data that gets read and updated is one of the things not copied (the underlying Check with a Status field). When the stock code was run with the race detector enabled this highly-relevant-to-the-test-scenario field was found to be racy. Changes: a) update the existing Clone method to include the Check field b) copy-on-write when those fields need to change rather than incrementally updating them in place. This made the observed behavior occur slightly less often. (2) If anything about how the runLocal method for node-local alias check logic was ever flawed, there was no fallback option. Those checks are purely edge-triggered and failure to properly notice a single edge transition would leave the alias check incorrect until the next flap of the aliased check. The change was to introduce a fallback timer to act as a control loop to double check the alias check matches the aliased check every minute (borrowing the duration from the non-local alias check logic body). This made the observed behavior eventually go away when it did occur. (3) Originally I thought there were two main actions involved in the data race: A. The act of adding the original check (from disk recovery) and its first health evaluation. B. The act of the HTTP API requests coming in and resetting the local state when re-registering the same services and checks. It took awhile for me to realize that there's a third action at work: C. The goroutines associated with the original check and the later checks. The actual sequence of actions that was causing the bad behavior was that the API actions result in the original check to be removed and re-added _without waiting for the original goroutine to terminate_. This means for brief windows of time during check definition edits there are two goroutines that can be sending updates for the alias check status. In extremely unlikely scenarios the original goroutine sees the aliased check start up in `critical` before being removed but does not get the notification about the nearly immediate update of that check to `passing`. This is interlaced wit the new goroutine coming up, initializing its base case to `passing` from the current state and then listening for new notifications of edge triggers. If the original goroutine "finishes" its update, it then commits one more write into the local state of `critical` and exits leaving the alias check no longer reflecting the underlying check. The correction here is to enforce that the old goroutines must terminate before spawning the new one for alias checks.	6 years ago
Matt Keeler	f665695b6b	Ensure ServiceName is populated correctly for agent service checks Also update some snapshot agent docs * Enforce correct permissions when registering a check Previously we had attempted to enforce service:write for a check associated with a service instead of node:write on the agent but due to how we decoded the health check from the request it would never do it properly. This commit fixes that. * Update website/source/docs/commands/snapshot/agent.html.markdown.erb Co-Authored-By: mkeeler <mkeeler@users.noreply.github.com>	6 years ago
Aestek	f669bb7b0f	Add support for DNS config hot-reload (#4875 ) The DNS config parameters `recursors` and `dns_config.*` are now hot reloaded on SIGHUP or `consul reload` and do not need an agent restart to be modified. Config is stored in an atomic.Value and loaded at the beginning of each request. Reloading only affects requests that start _after_ the reload. Ongoing requests are not affected. To match the current behavior the recursor handler is loaded and unloaded as needed on config reload.	6 years ago

Hans Hasselberg	7e11dd82aa	agent: enable reloading of tls config (#5419 ) This PR introduces reloading tls configuration. Consul will now be able to reload the TLS configuration which previously required a restart. It is not yet possible to turn TLS ON or OFF with these changes. Only when TLS is already turned on, the configuration can be reloaded. Most importantly the certificates and CAs.	6 years ago
Hans Hasselberg	786b3b1095	Centralise tls configuration part 1 (#5366 ) In order to be able to reload the TLS configuration, we need one way to generate the different configurations. This PR introduces a `tlsutil.Configurator` which holds a `tlsutil.Config`. Afterwards it is responsible for rendering every `tls.Config`. In this particular PR I moved `IncomingHTTPSConfig`, `IncomingTLSConfig`, and `OutgoingTLSWrapper` into `tlsutil.Configurator`. This PR is a pure refactoring - not a single feature added. And not a single test added. I only slightly modified existing tests as necessary.	6 years ago

Frank Schroeder	c94751ad43	test: replace porter tool with freeport lib This patch removes the porter tool which hands out free ports from a given range with a library which does the same thing. The challenge for acquiring free ports in concurrent go test runs is that go packages are tested concurrently and run in separate processes. There has to be some inter-process synchronization in preventing processes allocating the same ports. freeport allocates blocks of ports from a range expected to be not in heavy use and implements a system-wide mutex by binding to the first port of that block for the lifetime of the application. Ports are then provided sequentially from that block and are tested on localhost before being returned as available.	7 years ago
Frank Schröder	1e461110e6	agent: consolidate handling of 405 Method Not Allowed (#3405 ) * agent: consolidate http method not allowed checks This patch uses the error handling of the http handlers to handle HTTP method not allowed errors across all available endpoints. It also adds a test for testing whether the endpoints respond with the correct status code. * agent: do not panic on metrics tests * agent: drop other tests for MethodNotAllowed * agent: align /agent/join with reality /agent/join uses PUT instead of GET as documented. * agent: align /agent/check/{fail,warn,pass} with reality /agent/check/{fail,warn,pass} uses PUT instead of GET as documented. * fix some tests * Drop more tests for method not allowed * Align TestAgent_RegisterService_InvalidAddress with reality * Changes API client join to use PUT instead of GET. * Fixes agent endpoint verbs and removes obsolete tests. * Updates the change log.	7 years ago
Frank Schröder	12216583a1	New config parser, HCL support, multiple bind addrs (#3480 ) * new config parser for agent This patch implements a new config parser for the consul agent which makes the following changes to the previous implementation: * add HCL support * all configuration fragments in tests and for default config are expressed as HCL fragments * HCL fragments can be provided on the command line so that they can eventually replace the command line flags. * HCL/JSON fragments are parsed into a temporary Config structure which can be merged using reflection (all values are pointers). The existing merge logic of overwrite for values and append for slices has been preserved. * A single builder process generates a typed runtime configuration for the agent. The new implementation is more strict and fails in the builder process if no valid runtime configuration can be generated. Therefore, additional validations in other parts of the code should be removed. The builder also pre-computes all required network addresses so that no address/port magic should be required where the configuration is used and should therefore be removed. * Upgrade github.com/hashicorp/hcl to support int64 * improve error messages * fix directory permission test * Fix rtt test * Fix ForceLeave test * Skip performance test for now until we know what to do * Update github.com/hashicorp/memberlist to update log prefix * Make memberlist use the default logger * improve config error handling * do not fail on non-existing data-dir * experiment with non-uniform timeouts to get a handle on stalled leader elections * Run tests for packages separately to eliminate the spurious port conflicts * refactor private address detection and unify approach for ipv4 and ipv6. Fixes #2825 * do not allow unix sockets for DNS * improve bind and advertise addr error handling * go through builder using test coverage * minimal update to the docs * more coverage tests fixed * more tests * fix makefile * cleanup * fix port conflicts with external port server 'porter' * stop test server on error * do not run api test that change global ENV concurrently with the other tests * Run remaining api tests concurrently * no need for retry with the port number service * monkey patch race condition in go-sockaddr until we understand why that fails * monkey patch hcl decoder race condidtion until we understand why that fails * monkey patch spurious errors in strings.EqualFold from here * add test for hcl decoder race condition. Run with go test -parallel 128 * Increase timeout again * cleanup * don't log port allocations by default * use base command arg parsing to format help output properly * handle -dc deprecation case in Build * switch autopilot.max_trailing_logs to int * remove duplicate test case * remove unused methods * remove comments about flag/config value inconsistencies * switch got and want around since the error message was misleading. * Removes a stray debug log. * Removes a stray newline in imports. * Fixes TestACL_Version8. * Runs go fmt. * Adds a default case for unknown address types. * Reoders and reformats some imports. * Adds some comments and fixes typos. * Reorders imports. * add unix socket support for dns later * drop all deprecated flags and arguments * fix wrong field name * remove stray node-id file * drop unnecessary patch section in test * drop duplicate test * add test for LeaveOnTerm and SkipLeaveOnInt in client mode * drop "bla" and add clarifying comment for the test * split up tests to support enterprise/non-enterprise tests * drop raft multiplier and derive values during build phase * sanitize runtime config reflectively and add test * detect invalid config fields * fix tests with invalid config fields * use different values for wan sanitiziation test * drop recursor in favor of recursors * allow dns_config.udp_answer_limit to be zero * make sure tests run on machines with multiple ips * Fix failing tests in a few more places by providing a bind address in the test * Gets rid of skipped TestAgent_CheckPerformanceSettings and adds case for builder. * Add porter to server_test.go to make tests there less flaky * go fmt	7 years ago

Frank Schroeder	ea5b0f2c7c	agent: fix 'consul leave' shutdown race (#2880 ) When the agent is triggered to shutdown via an external 'consul leave' command delivered via the HTTP API then the client expects to receive a response when the agent is down. This creates a race on when to shutdown the agent itself like the RPC server, the checks and the state and the external endpoints like DNS and HTTP. This patch splits the shutdown process into two parts: * shutdown the agent * shutdown the endpoints (http and dns) They can be executed multiple times, concurrently and in any order but should be executed first agent, then endpoints to provide consistent behavior across all use cases. Both calls have to be executed for a proper shutdown. This could be partially hidden in a single function but would introduce some magic that happens behind the scenes which one has to know of but isn't obvious. Fixes #2880	8 years ago
