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.

auto-config: relax node name validation for JWT authorization (#15370)
* auto-config: relax node name validation for JWT authorization

This changes the JWT authorization logic to allow all non-whitespace,
non-quote characters when validating node names. Consul had previously
allowed these characters in node names, until this validation was added
to fix a security vulnerability with whitespace/quotes being passed to
the `bexpr` library. This unintentionally broke node names with
characters like `.` which aren't related to this vulnerability.

Prevent serving TLS via ports.grpc (#15339)
Prevent serving TLS via ports.grpc

We remove the ability to run the ports.grpc in TLS mode to avoid
confusion and to simplify configuration. This breaking change
ensures that any user currently using ports.grpc in an encrypted
mode will receive an error message indicating that ports.grpc_tls
must be explicitly used.

The suggested action for these users is to simply swap their ports.grpc
to ports.grpc_tls in the configuration file. If both ports are defined,
or if the user has not configured TLS for grpc, then the error message
will not be printed.

cache: refactor agent cache fetching to prevent unnecessary fetches on error (#14956)
This continues the work done in #14908 where a crude solution to prevent a
goroutine leak was implemented. The former code would launch a perpetual
goroutine family every iteration (+1 +1) and the fixed code simply caused a
new goroutine family to first cancel the prior one to prevent the
leak (-1 +1 == 0).

This PR refactors this code completely to:

- make it more understandable
- remove the recursion-via-goroutine strangeness
- prevent unnecessary RPC fetches when the prior one has errored.

The core issue arose from a conflation of the entry.Fetching field to mean:

- there is an RPC (blocking query) in flight right now
- there is a goroutine running to manage the RPC fetch retry loop

The problem is that the goroutine-leak-avoidance check would treat
Fetching like (2), but within the body of a goroutine it would flip that
boolean back to false before the retry sleep. This would cause a new
chain of goroutines to launch which #14908 would correct crudely.

The refactored code uses a plain for-loop and changes the semantics
to track state for "is there a goroutine associated with this cache entry"
instead of the former.

We use a uint64 unique identity per goroutine instead of a boolean so
that any orphaned goroutines can tell when they've been replaced when
the expiry loop deletes a cache entry while the goroutine is still running
and is later replaced.

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.

freddygv 5fbb26525b Add awareness of server mode to TLS configurator
Preivously the TLS configurator would default to presenting auto TLS
certificates as client certificates.

Server agents should not have this behavior and should instead present
the manually configured certs. The autoTLS certs for servers are
exclusively used for peering and should not be used as the default for
outbound communication.

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 vault namespaces in connect CA (#12904)
* Support vault namespaces in connect CA

Follow on to some missed items from #12655

From an internal ticket "Support standard "Vault namespace in the
path" semantics for Connect Vault CA Provider"

Vault allows the namespace to be specified as a prefix in the path of
a PKI definition, but our usage of the Vault API includes calls that
don't support a namespaced key. In particular the sys.* family of
calls simply appends the key, instead of prefixing the namespace in
front of the path.

Unfortunately it is difficult to reliably parse a path with a
namespace; only vault knows what namespaces are present, and the '/'
separator can be inside a key name, as well as separating path
elements. This is in use in the wild; for example
'dc1/intermediate-key' is a relatively common naming schema.

Instead we add two new fields: RootPKINamespace and
IntermediatePKINamespace, which are the absolute namespace paths
'prefixed' in front of the respective PKI Paths.
