Daniel Nephin d669226784 ca: fix a test
This test does not use Vault, so does not need ca.SkipIfVaultNotPresent
2022-02-28 16:26:18 -05:00
Daniel Nephin 1f00ede559 ca: require that tests that use Vault are named correctly
Previously we were using two different criteria to decide where to run a
test.  The main `go-test` job would skip Vault tests based on the
presence of the `vault` binary, but the `test-connect-ca-providers` job
would run tests based on the name.

This led to a scenario where a test may never run in CI.

To fix this problem I added a name check to the function we use to skip
the test. This should ensure that any test that requires vault is named
correctly to be run as part of the `test-connect-ca-providers` job.

At the same time I relaxed the regex we use. I verified this runs the
same tests using `go test --list Vault`.  I made this change because a
bunch of tests in `agent/connect/ca` used `Vault` in the name, without
the underscores. Instead of changing a bunch of test names, this seemed
easier.

With this approach, the worst case is that we run a few extra tests in
the `test-connect-ca-providers` job, which doesn't seem like a problem.

server: suppress spurious blocking query returns where multiple config entries are involved (#12362)
Starting from and extending the mechanism introduced in #12110 we can specially handle the 3 main special Consul RPC endpoints that react to many config entries in a single blocking query in Connect:

- `DiscoveryChain.Get`
- `ConfigEntry.ResolveServiceConfig`
- `Intentions.Match`

All of these will internally watch for many config entries, and at least one of those will likely be not found in any given query. Because these are blends of multiple reads the exact solution from #12110 isn't perfectly aligned, but we can tweak the approach slightly and regain the utility of that mechanism.

### No Config Entries Found

In this case, despite looking for many config entries none may be found at all. Unlike #12110 in this scenario we do not return an empty reply to the caller, but instead synthesize a struct from default values to return. This can be handled nearly identically to #12110 with the first 1-2 replies being non-empty payloads followed by the standard spurious wakeup suppression mechanism from #12110.

### No Change Since Last Wakeup

Once a blocking query loop on the server has completed and slept at least once, there is a further optimization we can make here to detect if any of the config entries that were present at specific versions for the prior execution of the loop are identical for the loop we just woke up for. In that scenario we can return a slightly different internal sentinel error and basically externally handle it similar to #12110.

This would mean that even if 20 discovery chain read RPC handling goroutines wakeup due to the creation of an unrelated config entry, the only ones that will terminate and reply with a blob of data are those that genuinely have new data to report.

### Extra Endpoints

Since this pattern is pretty reusable, other key config-entry-adjacent endpoints used by `agent/proxycfg` also were updated:

- `ConfigEntry.List`
- `Internal.IntentionUpstreams` (tproxy)

catalog: compare node names case insensitively in more places (#12444)
Many places in consul already treated node names case insensitively.
The state store indexes already do it, but there are a few places that
did a direct byte comparison which have now been corrected.

One place of particular consideration is ensureCheckIfNodeMatches
which is executed during snapshot restore (among other places). If a
node check used a slightly different casing than the casing of the node
during register then the snapshot restore here would deterministically
fail. This has been fixed.

Primary approach:

    git grep -i "node.*[!=]=.*node" -- ':!*_test.go' ':!docs'
    git grep -i '\[[^]]*member[^]]*\]
    git grep -i '\[[^]]*\(member\|name\|node\)[^]]*\]' -- ':!*_test.go' ':!website' ':!ui' ':!agent/proxycfg/testing.go:' ':!*.md'

server: partly fix config entry replication issue that prevents replication in some circumstances (#12307)
There are some cross-config-entry relationships that are enforced during
"graph validation" at persistence time that are required to be
maintained. This means that config entries may form a digraph at times.

Config entry replication procedes in a particular sorted order by kind
and name.

Occasionally there are some fixups to these digraphs that end up
replicating in the wrong order and replicating the leaves
(ingress-gateway) before the roots (service-defaults) leading to
replication halting due to a graph validation error related to things
like mismatched service protocol requirements.

This PR changes replication to give each computed change (upsert/delete)
a fair shot at being applied before deciding to terminate that round of
replication in error. In the case where we've simply tried to do the
operations in the wrong order at least ONE of the outstanding requests
will complete in the right order, leading the subsequent round to have
fewer operations to do, with a smaller likelihood of graph validation
errors.

This does not address all scenarios, but for scenarios where the edits
are being applied in the wrong order this should avoid replication
halting.

Fixes #9319

The scenario that is NOT ADDRESSED by this PR is as follows:

1. create: service-defaults: name=new-web, protocol=http
2. create: service-defaults: name=old-web, protocol=http
3. create: service-resolver: name=old-web, redirect-to=new-web
4. delete: service-resolver: name=old-web
5. update: service-defaults: name=old-web, protocol=grpc
6. update: service-defaults: name=new-web, protocol=grpc
7. create: service-resolver: name=old-web, redirect-to=new-web

If you shutdown dc2 just before (4) and turn it back on after (7)
replication is impossible as there is no single edit you can make to
make forward progress.

The interface is documented as 'Sign will only return the leaf', and the other providers

is likely just something we missed. It doesn't break anything , but it does cause confusing cert chains
in the API response which could break something in the future.

Daniel Nephin 4b33bdf396 Make blockingQuery efficient with 'not found' results.
By using the query results as state.

Blocking queries are efficient when the query matches some results,
because the ModifyIndex of those results, returned as queryMeta.Mindex,
will never change unless the items themselves change.

Blocking queries for non-existent items are not efficient because the
queryMeta.Index can (and often does) change when other entities are
written.

This commit reduces the churn of these queries by using a different
comparison for "has changed". Instead of using the modified index, we
use the existence of the results. If the previous result was "not found"
and the new result is still "not found", we know we can ignore the
modified index and continue to block.

This is done by setting the minQueryIndex to the returned
queryMeta.Index, which prevents the query from returning before a state
change is observed.

Daniel Nephin 897b953f66 Add a test for blocking query on non-existent entry
This test shows how blocking queries are not efficient when the query
returns no results.  The test fails with 100+ calls instead of the
expected 2.

This test is still a bit flaky because it depends on the timing of the
writes. It can sometimes return 3 calls.

A future commit should fix this and make blocking queries even more
optimal for not-found results.

- ensure that there's no function argument joint ownership between the caller of a function and the local state when calling `AddService`, `AddCheck`, and related using `copystructure` for now.

freddygv ceb52d649a Account for upstream targets in another DC.
Transparent proxies typically cannot dial upstreams in remote
datacenters. However, if their upstream configures a redirect to a
remote DC then the upstream targets will be in another datacenter.

In that sort of case we should use the WAN address for the passthrough.
2022-02-10 17:01:57 -07:00
freddygv cbea3d203c Fix race of upstreams with same passthrough ip
Due to timing, a transparent proxy could have two upstreams to dial
directly with the same address.

For example:
- The orders service can dial upstreams shipping and payment directly.
- An instance of shipping at address 10.0.0.1 is deregistered.
- Payments is scaled up and scheduled to have address 10.0.0.1.
- The orders service receives the event for the new payments instance
before seeing the deregistration for the shipping instance. At this
point two upstreams have the same passthrough address and Envoy will
reject the listener configuration.

To disambiguate this commit considers the Raft index when storing
passthrough addresses. In the example above, 10.0.0.1 would only be
associated with the newer payments service instance.
2022-02-10 17:01:57 -07:00
freddygv 659ebc05a9 Ensure passthrough addresses get cleaned up
Transparent proxies can set up filter chains that allow direct
connections to upstream service instances. Services that can be dialed
directly are stored in the PassthroughUpstreams map of the proxycfg
snapshot.

Previously these addresses were not being cleaned up based on new
service health data. The list of addresses associated with an upstream
service would only ever grow.

As services scale up and down, eventually they will have instances
assigned to an IP that was previously assigned to a different service.
When IP addresses are duplicated across filter chain match rules the
listener config will be rejected by Envoy.

This commit updates the proxycfg snapshot management so that passthrough
addresses can get cleaned up when no longer associated with a given
upstream.

There is still the possibility of a race condition here where due to
timing an address is shared between multiple passthrough upstreams.
That concern is mitigated by #12195, but will be further addressed
in a follow-up.

Daniel Nephin 608597c7b6 ca: relax and move private key type/bit validation for vault
This commit makes two changes to the validation.

Previously we would call this validation in GenerateRoot, which happens
both on initialization (when a follower becomes leader), and when a
configuration is updated. We only want to do this validation during
config update so the logic was moved to the UpdateConfiguration
function.

Previously we would compare the config values against the actual cert.
This caused problems when the cert was created manually in Vault (not
created by Consul).  Now we compare the new config against the previous
config. Using a already created CA cert should never error now.

Adding the key bit and types to the config should only error when
the previous values were not the defaults.

Daniel Nephin 7839b2d7e0 ca: add a test that uses an intermediate CA as the primary CA
This test found a bug in the secondary. We were appending the root cert
to the PEM, but that cert was already appended. This was failing
validation in Vault here:
https://github.com/hashicorp/vault/blob/sdk/v0.3.0/sdk/helper/certutil/types.go#L329

Previously this worked because self signed certs have the same
SubjectKeyID and AuthorityKeyID. So having the same self-signed cert
repeated doesn't fail that check.

However with an intermediate that is not self-signed, those values are
different, and so we fail the check. A test I added in a previous commit
should show that this continues to work with self-signed root certs as
well.

ACLIdentity from a method.

xds: fix for delta xDS reconnect bug in LDS/CDS (#12174)
When a wildcard xDS type (LDS/CDS/SRDS) reconnects from a delta xDS stream,
prior to envoy `1.19.0` it would populate the `ResourceNamesSubscribe` field
with the full list of currently subscribed items, instead of simply omitting it
to infer that it wanted everything (which is what wildcard mode means).

This upstream issue was filed in envoyproxy/envoy#16063 and fixed in
envoyproxy/envoy#16153 which went out in Envoy `1.19.0` and is fixed in later
versions (later refactored in envoyproxy/envoy#16855).

This PR conditionally forces LDS/CDS to be wildcard-only even when the
connected Envoy requests a non-wildcard subscription, but only does so on
versions prior to `1.19.0`, as we should not need to do this on later versions.

This fixes the failure case as described here: #11833 (comment)

proxycfg: introduce explicit UpstreamID in lieu of bare string (#12125)
The gist here is that now we use a value-type struct proxycfg.UpstreamID
as the map key in ConfigSnapshot maps where we used to use "upstream
id-ish" strings. These are internal only and used just for bidirectional
trips through the agent cache keyspace (like the discovery chain target
struct).

For the few places where the upstream id needs to be projected into xDS,
that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS
inject the partition and namespace into these things without making
stuff like the golden testdata diverge.

Daniel Nephin d57dec5878 ca: remove unnecessary var, and slightly reduce cyclo complexity
`newIntermediate` is always equal to `needsNewIntermediate`, so we can
remove the extra variable and use the original directly.

Also remove the `activeRoot.ID != newActiveRoot.ID` case from an if,
because that case is already checked above, and `needsNewIntermediate` will
already be true in that case.

This condition now reads a lot better:

> Persist a new root if we did not have one before, or if generated a new intermediate.

Daniel Nephin 0de7efb316 ca: remove unused provider.ActiveRoot call
In the previous commit the single use of this storedRoot was removed.

In this commit the original objective is completed. The
Provider.ActiveRoot is being removed because

1. the secondary should get the active root from the Consul primary DC,
   not the provider, so that secondary DCs do not need to communicate
   with a provider instance in a different DC.
2. so that the Provider.ActiveRoot interface can be changed without
   impacting other code paths.
2022-01-06 16:56:48 -05:00
Daniel Nephin d0578c6dfc ca: extract the lookup of the active primary CA
This method had only one caller, which always looked for the active
root. This commit moves the lookup into the method to reduce the logic
in the one caller.

This is being done in preparation for a larger change. Keeping this
separate so it is easier to see.

The `storedRootID != primaryRoots.ActiveRootID` is being removed because
these can never be different.

The `storedRootID` comes from `provider.ActiveRoot`, the
`primaryRoots.ActiveRootID` comes from the store `CARoot` from the
primary. In both cases the source of the data is the primary DC.

Technically they could be different if someone modified the provider
outside of Consul, but that would break many things, so is not a
supported flow.

If these were out of sync because of ordering of events then the
secondary will soon receive an update to `primaryRoots` and everything
will be sorted out again.

Daniel Nephin abac8baa5d ca: remove one call to provider.ActiveRoot
ActiveRoot should not be called from the secondary DC, because there
should not be a requirement to run the same Vault instance in a
secondary DC. SignIntermediate is called in a secondary DC, so it should
not call ActiveRoot

We would also like to change the interface of ActiveRoot so that we can
support using an intermediate cert as the primary CA in Consul. In
preparation for making that change I am reducing the number of calls to
ActiveRoot, so that there are fewer code paths to modify when the
interface changes.

This change required a change to the mockCAServerDelegate we use in
tests. It was returning the RootCert for SignIntermediate, but that is
not an accurate fake of production. In production this would also be a
separate cert.
2022-01-06 16:55:50 -05:00
Daniel Nephin eaa084fd41 ca: remove redundant append of an intermediate cert
Immediately above this line we are already appending the full list of
intermediates. The `provider.ActiveIntermediate` MUST be in this list of
intermediates because it must be available to all the other non-leader
Servers.  If it was not in this list of intermediates then any proxy
that received data from a non-leader would have the wrong certs.

This is being removed now because we are planning on changing the
`Provider.ActiveIntermediate` interface, and removing these extra calls ahead of
time helps make that change easier.

Daniel Nephin 11f4cdaa49 ca: only generate a single private key for the whole test case

Update the `/agent/check/deregister/` API endpoint to return a 404
HTTP response code when an attempt is made to de-register a check ID
that does not exist on the agent.

This brings the behavior of /agent/check/deregister/ in line with the
behavior of /agent/service/deregister/ which was changed in #10632 to
similarly return a 404 when de-registering non-existent services.

Jared Kirschner b393c90ce7 Clarify service and check error messages (use ID)
Error messages related to service and check operations previously included
the following substrings:
- service %q
- check %q

From this error message, it isn't clear that the expected field is the ID for
the entity, not the name. For example, if the user has a service named test,
the error message would read 'Unknown service "test"'. This is misleading -
a service with that *name* does exist, but not with that *ID*.

The substrings above have been modified to make it clear that ID is needed,
not name:
- service with ID %q
- check with ID %q

freddygv c5c290c503 Validate chains are associated with upstreams
Previously we could get into a state where discovery chain entries were
not cleaned up after the associated watch was cancelled. These changes
add handling for that case where stray chain references are encountered.

When a URL path is not found, return a non-empty message with the 404 status
code to help the user understand what went wrong. If the URL path was not
prefixed with '/v1/', suggest that may be the cause of the problem (which is a
common mistake).

Use anonymousToken when querying by secret ID (#11813)
Co-authored-by: Chris S. Kim <ckim@hashicorp.com>
Co-authored-by: Dan Upton <daniel@floppy.co>

This query has been incorrectly querying by accessor ID since New ACLs
were added. However, the legacy token compat allowed this to continue to
work, since it made a fallback query for the anonymousToken ID.

PR #11184 removed this legacy token query, which means that the query by
accessor ID is now the only check for the anonymous token's existence.

This PR updates the GetBySecret call to use the secret ID of the token.
