2022-11-01 10:51:13 -05:00
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.

freddygv 650e1e32e0 Update TLS configurator for peering traffic

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`.

Daniel Nephin 4afc24268d tlsutil: only AuthorizerServerConn when VerifyIncomingRPC is true
See github.com/hashicorp/consul/issues/11207

When VerifyIncomingRPC is false the TLS conn will not have the required certificates.

Daniel Nephin dc67042eac Invert the logic of outgoingRPCTLSDisabled
To remove the double negatives, which should make it easier to read.
2021-06-24 19:25:02 -04:00
Daniel Nephin 39f282c425 tlsutil: inline verifyIncomingHTTPS
This function was only used in one place, and the indirection makes it slightly
harder to see what the one caller is doing. Since it's only accesing a couple fields
it seems like the logic can exist in the one caller.
2021-06-24 19:25:02 -04:00
Daniel Nephin a25c817478 tlsutil: remove indirection and duplication
VerifyIncomingRPC and verifyIncomingRPC were duplicate functions, and
once one is removed, Config.verifyIncomingRPC is only called in one place.

Remove 2 of the 3 functions to make the behaviour easier to follow (less indirection).
2021-06-24 18:43:30 -04:00
Daniel Nephin 66ba2e2463 tlsutil: unexport and remove indirection
Unexport outgoingALPNRPCConfig since it is only used internally
Remove the MutualTLSCapable->mutualTLSCapable indirection, we only need the exported method.
Inline enableAgentTLSForChecks to make it more clear what it does, since it only has a single caller and is wrapping a single field lookup.

Daniel Nephin 2aad3f80fb tlsutil: reduce interface provided to auto-config
Replace two methods with a single one that returns the cert. This moves more
of the logic into the single caller (auto-config).

tlsutil.Configurator is widely used. By keeping it smaller and focused only on storing and
returning TLS config, we make the code easier to follow.

These two methods were more related to auto-config than to tlsutil, so reducing the interface
moves the logic closer to the feature that requires it.

Daniel Nephin 1ba5acb284 tlsutil: un-ptr and document the manual struct 2021-06-21 12:52:54 -04:00
Daniel Nephin a4432bb0b4 tlsutil: un-ptr and add godoc to autoTLs struct
the autoTLS field on Configurator is only set once. By making it a value receiver it
should be allocated as a single block of memory along with Configurator.

Also add godoc to document what it is used for.
2021-06-21 12:52:54 -04:00
Daniel Nephin 08cd772626 tlsutil: remove unused method
Method was only used in tests, and an equivalent function alraedy exists.
2021-06-21 12:52:54 -04:00
Daniel Nephin 8d9d6c6a09 tlsutil: unexport two types
These types are only used internally and should not be exported.

Also remove some unnecessary function wrapping.
2021-06-21 12:52:54 -04:00
Daniel Nephin bca33d818f tlsutil: remove the RLock from log
The log method only needed the lock because it accessed version. By using an atomic
instead of a lock, we can remove the risk that the comments call out, making log safer
to use.

Also updates the log name to match the function names, and adds some comments about how
the lock is used.
2021-06-18 12:13:30 -04:00
Daniel Nephin bcf23cd1b4 tlsutil: Un-method Configurator.check
The method receiver was never used. Also rename it and add a godoc comment.
2021-06-18 12:13:30 -04:00
Daniel Nephin b3fa778d91 tlsutil: fix a panic
UpdateAutoTLSCA would panic if either of the calls errored, because the read lock was being unlocked
incorrectly.

Christopher Broglie f0307c73e5 Add support for configuring TLS ServerName for health checks
Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes #9473.

Allow setting verify_incoming* when using auto_encrypt or auto_config (#8394)
Ensure that enabling AutoConfig sets the tls configurator properly

This also refactors the TLS configurator a bit so the naming doesn’t imply only AutoEncrypt as the source of the automatically setup TLS cert info.

wan federation via mesh gateways (#6884)
This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch:

There are several distinct chunks of code that are affected:

* new flags and config options for the server

* retry join WAN is slightly different

* retry join code is shared to discover primary mesh gateways from secondary datacenters

* because retry join logic runs in the *agent* and the results of that
  operation for primary mesh gateways are needed in the *server* there are
  some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur
  at multiple layers of abstraction just to pass the data down to the right
  layer.

* new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers

* the function signature for RPC dialing picked up a new required field (the
  node name of the destination)

* several new RPCs for manipulating a FederationState object:
  `FederationState:{Apply,Get,List,ListMeshGateways}`

* 3 read-only internal APIs for debugging use to invoke those RPCs from curl

* raft and fsm changes to persist these FederationStates

* replication for FederationStates as they are canonically stored in the
  Primary and replicated to the Secondaries.

* a special derivative of anti-entropy that runs in secondaries to snapshot
  their local mesh gateway `CheckServiceNodes` and sync them into their upstream
  FederationState in the primary (this works in conjunction with the
  replication to distribute addresses for all mesh gateways in all DCs to all
  other DCs)

* a "gateway locator" convenience object to make use of this data to choose
  the addresses of gateways to use for any given RPC or gossip operation to a
  remote DC. This gets data from the "retry join" logic in the agent and also
  directly calls into the FSM.

* RPC (`:8300`) on the server sniffs the first byte of a new connection to
  determine if it's actually doing native TLS. If so it checks the ALPN header
  for protocol determination (just like how the existing system uses the
  type-byte marker).

* 2 new kinds of protocols are exclusively decoded via this native TLS
  mechanism: one for ferrying "packet" operations (udp-like) from the gossip
  layer and one for "stream" operations (tcp-like). The packet operations
  re-use sockets (using length-prefixing) to cut down on TLS re-negotiation
  overhead.

* the server instances specially wrap the `memberlist.NetTransport` when running
  with gateway federation enabled (in a `wanfed.Transport`). The general gist is
  that if it tries to dial a node in the SAME datacenter (deduced by looking
  at the suffix of the node name) there is no change. If dialing a DIFFERENT
  datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh
  gateways to eventually end up in a server's :8300 port.

* a new flag when launching a mesh gateway via `consul connect envoy` to
  indicate that the servers are to be exposed. This sets a special service
  meta when registering the gateway into the catalog.

* `proxycfg/xds` notice this metadata blob to activate additional watches for
  the FederationState objects as well as the location of all of the consul
  servers in that datacenter.

* `xds:` if the extra metadata is in place additional clusters are defined in a
  DC to bulk sink all traffic to another DC's gateways. For the current
  datacenter we listen on a wildcard name (`server.<dc>.consul`) that load
  balances all servers as well as one mini-cluster per node
  (`<node>.server.<dc>.consul`)

* the `consul tls cert create` command got a new flag (`-node`) to help create
  an additional SAN in certs that can be used with this flavor of federation.

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.

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.
