* Allow setting the mesh gateway mode for an upstream in config files
* Add envoy integration test for mesh gateways
This necessitated many supporting changes in most of the other test cases.
Add remote mode mesh gateways integration test
* Display nicely Networks (CIDR) in runtime configuration
CIDR mask is displayed in binary in configuration.
This add support for nicely displaying CIDR in runtime configuration.
Currently, if a configuration contains the following lines:
"http_config": {
"allow_write_http_from": [
"127.0.0.0/8",
"::1/128"
]
}
A call to `/v1/agent/self?pretty` would display
"AllowWriteHTTPFrom": [
{
"IP": "127.0.0.0",
"Mask": "/wAAAA=="
},
{
"IP": "::1",
"Mask": "/////////////////////w=="
}
]
This PR fixes it and it will now display:
"AllowWriteHTTPFrom": [ "127.0.0.0/8", "::1/128" ]
* Added test for cidr nice rendering in `TestSanitize()`.
This fixes pathological cases where the write throughput and snapshot size are both so large that more than 10k log entries are written in the time it takes to restore the snapshot from disk. In this case followers that restart can never catch up with leader replication again and enter a loop of constantly downloading a full snapshot and restoring it only to find that snapshot is already out of date and the leader has truncated its logs so a new snapshot is sent etc.
In general if you need to adjust this, you are probably abusing Consul for purposes outside its design envelope and should reconsider your usage to reduce data size and/or write volume.
Both 'consul config write' and server bootstrap config entries take a
decoding detour through mapstructure on the way from HCL to an actual
struct. They both may take in snake_case or CamelCase (for consistency)
so need very similar handling.
Unfortunately since they are operating on mirror universes of structs
(api.* vs structs.*) the code cannot be identitical, so try to share the
kind-configuration and duplicate the rest for now.

* ui: Only inject {{.ContentPath}} if we are makeing a prod build...
...otherwise we just use the current rootURL
This gets injected into a <base /> node which solves the assets path
problem but not the ember problem
* ui: Pull out the <base href=""> value and inject it into ember env
See previous commit:
The <base href=""> value is 'sometimes' injected from go at index
serve time. We pass this value down to ember by overwriting the ember
config that is injected via a <meta> tag. This has to be done before
ember bootup.
Sometimes (during testing and development, basically not production)
this is injected with the already existing value, in which case this
essentially changes nothing.
The code here is slightly abstracted away from our specific usage to
make it easier for anyone else to use, and also make sure we can cope
with using this same method to pass variables down from the CLI through
to ember in the future.
* ui: We can't use <base /> move everything to javascript (#5941)
Unfortuantely we can't seem to be able to use <base> and rootURL
together as URL paths will get doubled up (`ui/ui/`).
This moves all the things that we need to interpolate with .ContentPath
to the `startup` javascript so we can conditionally print out
`{{.ContentPath}}` in lots of places (now we can't use base)
* fixed when we serve index.html
* ui: For writing a ContentPath, we also need to cope with testing... (#5945)
...and potentially more environments
Testing has more additional things in a separate index.html in `tests/`
This make the entire thing a little saner and uses just javascriopt
template literals instead of a pseudo handbrake synatx for our
templating of these files.
Intead of just templating the entire file this way, we still only
template `{{content-for 'head'}}` and `{{content-for 'body'}}`
in this way to ensure we support other plugins/addons
* build: Loosen up the regex for retrieving the CONSUL_VERSION (#5946)
* build: Loosen up the regex for retrieving the CONSUL_VERSION
1. Previously the `sed` replacement was searching for the CONSUL_VERSION
comment at the start of a line, it no longer does this to allow for
indentation.
2. Both `grep` and `sed` where looking for the omment at the end of the
line. We've removed this restriction here. We don't need to remove it
right now, but if we ever put the comment followed by something here the
searching would break.
3. Added `xargs` for trimming the resulting version string. We aren't
using this already in the rest of the scripts, but we are pretty sure
this is available on most systems.
* ui: Fix erroneous variable, and also force an ember cache clean on build
1. We referenced a variable incorrectly here, this fixes that.
2. We also made sure that every `make` target clears ember's `tmp` cache
to ensure that its not using any caches that have since been edited
everytime we call a `make` target.

* Support for maximum size for Output of checks
This PR allows users to limit the size of output produced by checks at the agent
and check level.
When set at the agent level, it will limit the output for all checks monitored
by the agent.
When set at the check level, it can override the agent max for a specific check but
only if it is lower than the agent max.
Default value is 4k, and input must be at least 1.
This allows addresses to be tagged at the service level similar to what we allow for nodes already. The address translation that can be enabled with the `translate_wan_addrs` config was updated to take these new addresses into account as well.
Roles are named and can express the same bundle of permissions that can
currently be assigned to a Token (lists of Policies and Service
Identities). The difference with a Role is that it not itself a bearer
token, but just another entity that can be tied to a Token.
This lets an operator potentially curate a set of smaller reusable
Policies and compose them together into reusable Roles, rather than
always exploding that same list of Policies on any Token that needs
similar permissions.
This also refactors the acl replication code to be semi-generic to avoid
3x copypasta.

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.
This PR adds two features which will be useful for operators when ACLs are in use.
1. Tokens set in configuration files are now reloadable.
2. If `acl.enable_token_persistence` is set to `true` in the configuration, tokens set via the `v1/agent/token` endpoint are now persisted to disk and loaded when the agent starts (or during configuration reload)
Note that token persistence is opt-in so our users who do not want tokens on the local disk will see no change.
Some other secondary changes:
* Refactored a bunch of places where the replication token is retrieved from the token store. This token isn't just for replicating ACLs and now it is named accordingly.
* Allowed better paths in the `v1/agent/token/` API. Instead of paths like: `v1/agent/token/acl_replication_token` the path can now be just `v1/agent/token/replication`. The old paths remain to be valid.
* Added a couple new API functions to set tokens via the new paths. Deprecated the old ones and pointed to the new names. The names are also generally better and don't imply that what you are setting is for ACLs but rather are setting ACL tokens. There is a minor semantic difference there especially for the replication token as again, its no longer used only for ACL token/policy replication. The new functions will detect 404s and fallback to using the older token paths when talking to pre-1.4.3 agents.
* Docs updated to reflect the API additions and to show using the new endpoints.
* Updated the ACL CLI set-agent-tokens command to use the non-deprecated APIs.
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.
Adds two new configuration parameters "dns_config.use_cache" and
"dns_config.cache_max_age" controlling how DNS requests use the agent
cache when querying servers.
* Support rate limiting and concurrency limiting CSR requests on servers; handle CA rotations gracefully with jitter and backoff-on-rate-limit in client
* Add CSR rate limiting docs
* Fix config naming and add tests for new CA configs
* Add State storage and LastResult argument into Cache so that cache.Types can safely store additional data that is eventually expired.
* New Leaf cache type working and basic tests passing. TODO: more extensive testing for the Root change jitter across blocking requests, test concurrent fetches for different leaves interact nicely with rootsWatcher.
* Add multi-client and delayed rotation tests.
* Typos and cleanup error handling in roots watch
* Add comment about how the FetchResult can be used and change ca leaf state to use a non-pointer state.
* Plumb test override of root CA jitter through TestAgent so that tests are deterministic again!
* Fix failing config test
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description
At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.
On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.
Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
A server running the new system must still support other clients using the legacy system.
A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.
So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.
* Add -enable-local-script-checks options
These options allow for a finer control over when script checks are enabled by
giving the option to only allow them when they are declared from the local
file system.
* Add documentation for the new option
* Nitpick doc wording
