Somewhere around osquery 4.4.0 these messages were added to query
responses. We can now expose them to the API clients rather than using
the placeholder text.
Required for #192
When an osqueryd agent sends an enroll request it automatically sends
some details about the system. We now save these details which helps
ensure we send the correct platform config.
Closes#2065
Instead of trying to decode and re-encode status logs, we now write them directly as they come in.
This change prevents future changes to the osquery status log file format (addition and deletion of fields ) from
affecting Fleet. A similar change was implemented in #1636 for result logs.
Closes#1664
Initially fleet decoded the incoming JSON sent to the log endpoint.
Then the log event would be written to a log writer by calling json.Encoder{}.Encode.
Re-encoding logs is lossy; whenever a new field is sent by osqueryd we don't keep up with them.
Instead of caring about the content of the OsqueryResultLog, fleet will now write all log results
exactly as sent to the server by osqueryd.
Closes#1632Closes#1615
Return `accelerate: 10` with distributed queries if we do not have host
details. This facilitates the host quickly joining all expected labels, as
`platform` gated label queries will not be returned until the detail queries
return with the platform.
Fixes#1421.
Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
As of recently, osquery will report when a distributed query fails. We now
expose errors over the results websocket. When a query errored on the host, the
`error` key in the result will be non-null. Note that osquery currently doesn't
provide any details so the error string will always be "failed". I anticipate
that we will fix this and the string is included for future-proofing.
Successful result:
```
{
"type": "result",
"data": {
"distributed_query_execution_id": 15,
"host": {
... omitted ...
},
"rows": [
{
"hour": "1"
}
],
"error": null
}
}
```
Failed result:
```
{
"type": "result",
"data": {
"distributed_query_execution_id": 14,
"host": {
... omitted ...
},
"rows": [
],
"error": "failed"
}
}
```
- Establish a pattern for host authentication
- Establish a pattern for error JSON
- Add transport and make endpoint functions
- Fix discovered bugs + update tests
