Daniel Nephin	89f41bddfe	Remove TTL from cacheEntryExpiry This should very slightly reduce the amount of memory required to store each item in the cache. It will also enable setting different TTLs based on the type of result. For example we may want to use a shorter TTL when the result indicates the resource does not exist, as storing these types of records could easily lead to a DOS caused by OOM.	5 years ago
Daniel Nephin	7246d8b6cb	agent/cache: Reduce differences between notify implementations These two notify functions are very similar. There appear to be just enough differences that trying to parameterize the differences may not improve things. For now, reduce some of the cosmetic differences so that the material differences are more obvious.	5 years ago
Daniel Nephin	66fbb13976	agent/cache: Inline the refresh function to make recursion more obvious fetch is already an exceptionally long function, but hiding the recrusion in a function call likely does not help.	5 years ago
Daniel Nephin	faeaed5d0c	agent/cache: Make the return values of getEntryLocked more obvious Use named returned so that the caller has a better idea of what these bools mean. Return early to reduce the scope, and make it more obvious what values are returned in which cases. Also reduces the number of conditional expressions in each case.	5 years ago

Pierre Souchay	1b4218a068	fix flaky TestReplication_FederationStates test due to race conditions (#7612 ) The test had two racy bugs related to memdb references. The first was when we initially populated data and retained the FederationState objects in a slice. Due to how the `inmemCodec` works these were actually the identical objects passed into memdb. The second was that the `checkSame` assertion function was reading from memdb and setting the RaftIndexes to zeros to aid in equality checks. This was mutating the contents of memdb which is a no-no. With this fix, the command: ``` i=0; while /usr/local/bin/go test -count=1 -timeout 30s github.com/hashicorp/consul/agent/consul -run '^(TestReplication_FederationStates)$'; do i=$((i + 1)); printf "$i "; done ``` That used to break on my machine in less than 20 runs is now running 150+ times without any issue. Might also fix #7575	5 years ago
Pierre Souchay	4a6569a4e3	tests: change default http_max_conns_per_client to 250 to ease tests (#7625 ) On recent Mac OS versions, the ulimit defaults to 256 by default, but many systems (eg: some Linux distributions) often limit this value to 1024. On validation of configuration, Consul now validates that the number of allowed files descriptors is bigger than http_max_conns_per_client. This make some unit tests failing on Mac OS. Use a less important value in unit test, so tests runs well by default on Mac OS without need for tuning the OS.	5 years ago

Daniel Nephin	c9a87be6ee	agent/cache: move typeEntry lookup to the edge This change moves all the typeEntry lookups to the first step in the exported methods, and makes unexporter internals accept the typeEntry struct. This change is primarily intended to make it easier to extract the container of caches from the Cache type. It may incidentally reduce locking in fetch, but that was not a goal.	5 years ago

Pierre Souchay	2a8bf45e38	agent: show warning when enable_script_checks is enabled without safty net (#7437 ) In order to enforce a bit security on Consul agents, add a new method in agent to highlight possible security issues. This does not return an error for now, but might in the future. For now, it detects issues such as: https://www.hashicorp.com/blog/protecting-consul-from-rce-risk-in-specific-configurations/ This would display this kind of messages: ``` 2020-03-11T18:27:49.873+0100 [ERROR] agent: [SECURITY] issue: error="using enable-script-checks without ACLs and without allow_write_http_from is DANGEROUS, use enable-local-script-checks instead see https://www.hashicorp.com/blog/protecting-consul-from-rce-risk-in-specific-configurations/" ```	5 years ago
Andy Lindeman	fb0a990e4d	agent: rewrite checks with proxy address, not local service address (#7518 ) Exposing checks is supposed to allow a Consul agent bound to a different IP address (e.g., in a different Kubernetes pod) to access healthchecks through the proxy while the underlying service binds to localhost. This is an important security feature that makes sure no external traffic reaches the service except through the proxy. However, as far as I can tell, this is subtly broken in the case where the Consul agent cannot reach the proxy over localhost. If a proxy is configured with: `{ LocalServiceAddress: "127.0.0.1", Checks: true }`, as is typical with a sidecar proxy, the Consul checks are currently rewritten to `127.0.0.1:<random port>`. A Consul agent that does not share the loopback address cannot reach this address. Just to make sure I was not misunderstanding, I tried configuring the proxy with `{ LocalServiceAddress: "<pod ip>", Checks: true }`. In this case, while the checks are rewritten as expected and the agent can reach the dynamic port, the proxy can no longer reach its backend because the traffic is no longer on the loopback interface. I think rewriting the checks to use `proxy.Address`, the proxy's own address, is more correct in this case. That is the IP where the proxy can be reached, both by other proxies and by a Consul agent running on a different IP. The local service address should continue to use `127.0.0.1` in most cases.	5 years ago
Andy Lindeman	c1cb18c648	proxycfg: support path exposed with non-HTTP2 protocol (#7510 ) If a proxied service is a gRPC or HTTP2 service, but a path is exposed using the HTTP1 or TCP protocol, Envoy should not be configured with `http2ProtocolOptions` for the cluster backing the path. A situation where this comes up is a gRPC service whose healthcheck or metrics route (e.g. for Prometheus) is an HTTP1 service running on a different port. Previously, if these were exposed either using `Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would still be configured to communicate with the path over HTTP2, which would not work properly.	5 years ago
Pierre Souchay	be1c5c4b48	config: validate system limits against limits.http_max_conns_per_client (#7434 ) I spent some time today on my local Mac to figure out why Consul 1.6.3+ was not accepting limits.http_max_conns_per_client. This adds an explicit check on number of file descriptors to be sure it might work (this is no guarantee as if many clients are reaching the agent, it might consume even more file descriptors) Anyway, many users are fighting with RLIMIT_NOFILE, having a clear message would allow them to figure out what to fix. Example of message (reload or start): ``` 2020-03-11T16:38:37.062+0100 [ERROR] agent: Error starting agent: error="system allows a max of 512 file descriptors, but limits.http_max_conns_per_client: 8192 needs at least 8212" ```	5 years ago

Daniel Nephin	dd40a1535e	testing: reduce verbosity of output log Previously the log output included the test name twice and a long date format. The test output is already grouped by test, so adding the test name did not add any new information.

Also fixed a bug in NewTestAgentWithFields where nil was returned instead of the test agent.	5 years ago
