This change optimizes live queries by pushing the computation of query
targets to the creation time of the query, and efficiently caching the
targets in Redis. This results in a huge performance improvement at both
steady-state, and when running live queries.
- Live queries are stored using a bitfield in Redis, and takes
advantage of bitfield operations to be extremely efficient.
- Only run Redis live query test when REDIS_TEST is set in environment
- Ensure that live queries are only sent to hosts when there is a client
listening for results. Addresses an existing issue in Fleet along with
appropriate cleanup for the refactored live query backend.
Fleet used significant resources storing the full network interface
information for each host. This data was unused, except to get the
IP and MAC of the primary interface. With these changes, only those
pieces of data are stored.
- Calculate and store primary IP and MAC
- Remove transaction for storing full interfaces
- Update targets search to use new IP and MAC columns
- Update frontend to use new new columns
This PR removes unused types, code, DB tables, and associated migrations that are unused since Fleet 2.0.
An existing migration was refactored, and should remain compatible with both existing and new Fleet installations.
Additional information is collected when host details are updated using
the queries specified in the Fleet configuration. This additional
information is then available in the host API responses.
This adds a SQL injection prevention for a case in which we cannot use
parameters in the query.
It is not clear that this was possible to exploit. If it was possible,
it would have required a valid login to the Fleet server.
Previously a Go package attempting to import Fleet packages would run
into an error like "server/kolide/emails.go:93:23: undefined: Asset".
This commit refactors bindata asset handling to allow importing Fleet as
a library without changing the typical developer experience.
- Add toggle to disable live queries in advanced settings
- Add new live query status endpoint (checks for disabled via config and Redis health)
- Update QueryPage UI to use new live query status endpoint
Implements #2140
Update the github.com/russellhaering/goxmldsig dependency and apply
the appropriate fixes for the API changes.
This is a preparation for integration with
github.com/AbGuthrie/goquery, which uses a newer version of the
dependency.
- Add logging for new campaigns
- Add logging for new query creations/modification/deletion
- Add usernames for logs found in labels, options, packs, osquery options, queries and scheduled queries where something is created, modified or deleted
- Add the server_url_prefix flag for configuring this functionality
- Add prefix handling to the server routes
- Refactor JS to use appropriate paths from modules
- Use JS template to get URL prefix into JS environment
- Update webpack config to support prefixing

Closes#1661
This change allows the images in Fleet emails to load properly from any
device with connectivity to github.com. Previously, emails might try to
load resources from a Kolide server not accessible from the email
client.
The asset URL will be based on the most recent git tag to accomodate
backwards-compatibility if the assets in the repo change.
Closes#1471
Adds Google Cloud PubSub logging for status and results.
This also changes the Write interface for logging modules to add a context.Context (only used by pubsub currently).
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
When LOGIN authentication was used, Fleet would send SMTP credentials
even if the connection the SMTP server was not secured via TLS.
Copying the pattern used in the standard library PlainAuth
implementation, we now only send credentials when the connection is
secure or the server is localhost.
- The most active NIC will be picked even if a formerly more active
interface still exists (previously, a NIC would stay primary as long
as it existed).
- Ignore link-local and loopback interfaces when choosing the primary.
- Fix bugs in which update status of the primary interface could be
reported incorrectly.
Fixes#2020
Fixes a regression introduced in 2.1.0 in which separate log lines are
no longer output separated by a newline. Now log lines in both output
plugins will do so.
- Refactor configuration for logging to use separate plugins
- Move existing filesystem logging to filesystem plugin
- Create new AWS firehose plugin
- Update documentation around logging
