adding config for request_limits (#15531)
* server: add placeholder glue for rate limit handler

This commit adds a no-op implementation of the rate-limit handler and
adds it to the `consul.Server` struct and setup code.

This allows us to start working on the net/rpc and gRPC interceptors and
config logic.

Refactor client RPC timeouts (#14965)
Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created.

Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.

proxycfg: rate-limit delivery of config snapshots (#14960)
Adds a user-configurable rate limiter to proxycfg snapshot delivery,
with a default limit of 250 updates per second.

This addresses a problem observed in our load testing of Consul
Dataplane where updating a "global" resource such as a wildcard
intention or the proxy-defaults config entry could starve the Raft or
Memberlist goroutines of CPU time, causing general cluster instability.

Derek Menteer 80d31458e5 Various cleanups. 2022-09-08 10:51:50 -05:00
Derek Menteer 1255a8a20d Add separate grpc_tls port.
To ease the transition for users, the original gRPC
port can still operate in a deprecated mode as either
plain-text or TLS mode. This behavior should be removed
in a future release whenever we no longer support this.

The resulting behavior from this commit is:
  `ports.grpc > 0 && ports.grpc_tls > 0` spawns both plain-text and tls ports.
  `ports.grpc > 0 && grpc.tls == undefined` spawns a single plain-text port.
  `ports.grpc > 0 && grpc.tls != undefined` spawns a single tls port (backwards compat mode).

Mark Anderson 346b68a441 Fix up enterprise version tag.
Changes to how the version string was handled created small regression with the release of consul 1.12.0 enterprise.

Many tools use the Config:Version field reported by the agent/self resource to determine whether Consul is an enterprise or OSS instance, expect something like 1.12.0+ent for enterprise and simply 1.12.0 for OSS. This was accidentally broken during the runup to 1.12.x

This work fixes the value returned by both the self endpoint in ["Config"]["Version"] and the metrics consul.version field.

Support per-listener TLS configuration ⚙️ (#12504)
Introduces the capability to configure TLS differently for Consul's
listeners/ports (i.e. HTTPS, gRPC, and the internal multiplexed RPC
port) which is useful in scenarios where you may want the HTTPS or
gRPC interfaces to present a certificate signed by a well-known/public
CA, rather than the certificate used for internal communication which
must have a SAN in the form `server.<dc>.consul`.

Add failures_before_warning to checks (#10969)
Signed-off-by: Jakub Sokołowski <jakub@status.im>

* agent: add failures_before_warning setting

The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.

The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.

When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

directly.
