Aestek 25f04fbd21 [Security] Add finer control over script checks (#4715)
* 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

Pierre Souchay 251156eb68 Added SOA configuration for DNS settings. (#4714)
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```
dig +multiline @localhost -p 8600 service.consul

Paul Banks 1e7eace066 Add SidecarService Syntax sugar to Service Definition (#4686)
* Added new Config for SidecarService in ServiceDefinitions.

* WIP: all the code needed for SidecarService is written... none of it is tested other than config :). Need API updates too.

* Test coverage for the new sidecarServiceFromNodeService method.

* Test API registratrion with SidecarService

* Recursive Key Translation 🤦

* Add tests for nested sidecar defintion arrays to ensure they are translated correctly

* Use dedicated internal state rather than Service Meta for tracking sidecars for deregistration.

Add tests for deregistration.

* API struct for agent register. No other endpoint should be affected yet.

* Additional test cases to cover updates to API registrations

Paul Banks b83bbf248c Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs

Pierre Souchay eddcf228ea Implementation of Weights Data structures (#4468)
* Implementation of Weights Data structures

Adding this datastructure will allow us to resolve the
issues #1088 and #4198

This new structure defaults to values:
```
   { Passing: 1, Warning: 0 }
```

Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.

* Implemented weights for DNS SRV Records

* DNS properly support agents with weight support while server does not (backwards compatibility)

* Use Warning value of Weights of 1 by default

When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.

Thus, we put a default value of 1 to be consistent with existing behaviour.

* Added documentation for new weight field in service description

* Better documentation about weights as suggested by @banks

* Return weight = 1 for unknown Check states as suggested by @banks

* Fixed typo (of -> or) in error message as requested by @mkeeler

* Fixed unstable unit test TestRetryJoin

* Fixed unstable tests

* Fixed wrong Fatalf format in `testrpc/wait.go`

* Added notes regarding DNS SRV lookup limitations regarding number of instances

* Documentation fixes and clarification regarding SRV records with weights as requested by @banks

* Rephrase docs

Adds a new command line flag -log-file for file based logging. (#4581)
* Added log-file flag to capture Consul logs in a user specified file

* Refactored code.

* Refactored code. Added flags to rotate logs based on bytes and duration

* Added the flags for log file and log rotation on the webpage

* Fixed TestSantize from failing due to the addition of 3 flags

* Introduced changes : mutex, data-dir log writes, rotation logic

* Added test for logfile and updated the default log destination for docs

* Log name now uses UnixNano

* TestLogFile is now uses t.Parallel()

* Removed unnecessary int64Val function

* Updated docs to reflect default log name for log-file

* No longer writes to data-dir and adds .log if the filename has no extension

agent/config: add managed proxy upstreams config to skip
agent/config will turn [{}] into {} (single element maps into a single
map) to work around HCL issues. These are resolved in HCL2 which I'm
sure Consul will switch to eventually.

This breaks the connect proxy configuration in service definition FILES
since we call this patch function. For now, let's just special-case skip
this. In the future we maybe Consul will adopt HCL2 and fix it, or we
can do something else if we want. This works and is tested.

This enables `consul agent -dev` to begin using Connect features with

🔒 Update supported TLS cipher suites
The list of cipher suites included in this commit are consistent with
the values and precedence in the [Golang TLS documentation](https://golang.org/src/crypto/tls/cipher_suites.go).

> **Note:** Cipher suites with RC4 are still included within the list
> of accepted values for compatibility, but **these cipher suites are
> not safe to use** and should be deprecated with warnings and
> subsequently removed. Support for RC4 ciphers has already been
> removed or disabled by default in many prominent browsers and tools,
> including Golang.

Pierre Souchay 0b7f620dc6 Allow to control the number of A/AAAA Record returned by DNS
This allows to have randomized resource records (i.e. each
answer contains only one IP, but the IP changes every request) for
A, AAAA records.

It will fix https://github.com/hashicorp/consul/issues/3355 and
https://github.com/hashicorp/consul/issues/3937

See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509
for details.

It basically add a new option called `a_record_limit` and will not
return more than a_record_limit when performing A, AAAA or ANY DNS
requests.

The existing `udp_answer_limit` option is still working but should
be considered as deprecated since it works only with DNS clients
not supporting EDNS.

Frank Schröder 874e350b2f config: add -config-format option (#3626)
* config: refactor ReadPath(s) methods without side-effects

Return the sources instead of modifying the state.

* config: clean data dir before every test

* config: add tests for config-file and config-dir

* config: add -config-format option

Starting with Consul 1.0 all config files must have a '.json' or '.hcl'
extension to make it unambigous how the data should be parsed. Some
automation tools generate temporary files by appending a random string
to the generated file which obfuscates the extension and prevents the
file type detection.

This patch adds a -config-format option which can be used to override
the auto-detection behavior by forcing all config files or all files
within a config directory independent of their extension to be
interpreted as of this format.

Merge pull request #3598 from hashicorp/issue-3397-error-with-extra-flags
The `consul agent` command was ignoring extra command line arguments
which can lead to confusion when the user has for example forgotten to
add a dash in front of an argument or is not using an `=` when setting
boolean flags to `true`. `-bootstrap true` is not the same as
`-bootstrap=true`, for example.

Since all command line flags are known and we don't expect unparsed
arguments we can return an error. However, this may make it slightly
more difficult in the future if we ever wanted to have these kinds of
arguments.

Frank Schröder 94f58199b1 agent: add option to discard health output (#3562)
* agent: add option to discard health output

In high volatile environments consul will have checks with "noisy"
output which changes every time even though the status does not change.
Since the output is stored in the raft log every health check update
unblocks a blocking call on health checks since the raft index has
changed even though the status of the health checks may not have changed
at all. By discarding the output of the health checks the users can
choose a different tradeoff. Less visibility on why a check failed in
exchange for a reduced change rate on the raft log.

* agent: discard output also when adding a check

* agent: add test for discard check output

* agent: update docs

* go vet

* Adds discard_check_output to reloadable config table.

* Updates the change log.

Frank Schröder 759ef8a1d4 config: add generic method to translate between CamelCase and snake_case (#3557)
* doc: document discrepancy between id and CheckID

* doc: document enable_tag_override change

* config: add TranslateKeys helper

TranslateKeys makes it easier to map between different representations
of internal structures. It allows to recursively map alias keys to
canonical keys in structured maps.

* config: use TranslateKeys for config file

This also adds support for 'enabletagoverride' and removes
the need for a separate CheckID alias field.

* config: remove dead code

* agent: use TranslateKeys for FixupCheckType

* agent: translate enable_tag_override during service registration

* doc: add '.hcl' as valid extension

* config: map ScriptArgs to args

* config: add comment for TranslateKeys

James Phillips bb12368eac Makes RPC handling more robust when rolling servers. (#3561)
* Adds client-side retry for no leader errors.

This paves over the case where the client was connected to the leader
when it loses leadership.

* Adds a configurable server RPC drain time and a fail-fast path for RPCs.

When a server leaves it gets removed from the Raft configuration, so it will
never know who the new leader server ends up being. Without this we'd be
doomed to wait out the RPC hold timeout and then fail. This makes things fail
a little quicker while a sever is draining, and since we added a client retry
AND since the server doing this has already shut down and left the Serf LAN,
clients should retry against some other server.

* Makes the RPC hold timeout configurable.

* Reorders struct members.

* Sets the RPC hold timeout default for test servers.

* Bumps the leave drain time up to 5 seconds.

* Robustifies retries with a simpler client-side RPC hold.

* Reverts untended delete.
