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.
Ensure that the peer stream replication rpc can successfully be used with TLS activated.
Also:
- If key material is configured for the gRPC port but HTTPS is not
enabled now TLS will still be activated for the gRPC port.
- peerstream replication stream opened by the establishing-side will now
ignore grpc.WithBlock so that TLS errors will bubble up instead of
being awkwardly delayed or suppressed

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`.
sync/atomic must be used with 64-bit aligned fields, and that alignment is difficult to
ensure unless the field is the first one in the struct.
https://golang.org/pkg/sync/atomic/#pkg-note-BUG.
As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:
ENABLE_AWS_PCA_TESTS=1 go test ./agent/connect/ca -run TestAWS
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.
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).
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.
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.
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.
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.
Embedded structs make code harder to navidate because an IDE can not show all uses of
the methods of that field separate from other uses.
Generally embedding of structs should only be used to satisfy an interface, and in this
case the Configurator type does not need to implement the RWMutex interface.
Using a TestSigner was causing problems because go1.16 has this change:
> CreateCertificate now verifies the generated certificate's signature
> using the signer's public key. If the signature is invalid, an error is
> returned, instead of a malformed certificate.
See https://golang.org/doc/go1.16#crypto/x509
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.
An old PR (#7623) was merged after #9585. The old code was incompatible with the new
changes, but none of the lines caused a git conflict so the merge was allowed.
The incompatible changes caused the tests to fail. This fixes the old code to
work with the new changes.

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.
Also fix a bug where Consul could segfault if TLS was enabled but no client certificate was provided. How no one has reported this as a problem I am not sure.
