With the new flag --management-diagnostics (an opt-in flag)
cloudflared's will be able to report additional diagnostic information
over the management.argotunnel.com request path.
Additions include the /metrics prometheus endpoint; which is already
bound to a local port via --metrics.
/debug/pprof/(goroutine|heap) are also provided to allow for remotely
retrieving heap information from a running cloudflared connector.
Allows for debugging the payloads that are sent in client mode to
the ssh server. Required to be run with --log-directory to capture
logging output. Additionally has maximum limit that is provided with
the flag that will only capture the first N number of reads plus
writes through the WebSocket stream. These reads/writes are not directly
captured at the packet boundary so some reconstruction from the
log messages will be required.
Added User-Agent for all out-going cloudflared access
tcp requests in client mode.
Added check to not run terminal logging in cloudflared access tcp
client mode to not obstruct the stdin and stdout.
I deliberately kept this as an unregistertimeout because that was the
intent. In the future we could change this to a UDPConnConfig if we want
to pass multiple values here.
The idea of this PR is simply to add a configurable unregister UDP
timeout.
In addition to supporting sampling support for streaming logs,
cloudflared tail also supports this via `--sample 0.5` to sample 50%
of your log events.
It might make sense for users to sometimes name their cloudflared
connectors to make identification easier than relying on hostnames that
TUN-7360 provides. This PR provides a new --label option to cloudflared
tunnel that a user could provide to give custom names to their
connectors.
Before this change, the only sure fire way to make sure you had a valid
Access token was to run `cloudflared access login <your domain>`. That
was because that command would actually make a preflight request to ensure
that the edge considered that token valid. The most common reasons a token
was no longer valid was expiration and revocation. Expiration is easy to
check client side, but revocation can only be checked at the edge.
This change adds the same flow that cfd access login did to the curl command.
It will preflight the request with the token and ensure that the edge thinks
its valid before making the real request.
With the management tunnels work, we allow calls to our edge service
using an access JWT provided by Tunnelstore. Given a connector ID,
this request is then proxied to the appropriate Cloudflare Tunnel.
This PR takes advantage of this flow and adds a new host_details
endpoint. Calls to this endpoint will result in cloudflared gathering
some details about the host: hostname (os.hostname()) and ip address
(localAddr in a dial).
Note that the mini spec lists 4 alternatives and this picks alternative
3 because:
1. Ease of implementation: This is quick and non-intrusive to any of our
code path. We expect to change how connection tracking works and
regardless of the direction we take, it may be easy to keep, morph
or throw this away.
2. The cloudflared part of this round trip takes some time with a
hostname call and a dial. But note that this is off the critical path
and not an API that will be exercised often.
cloudflared tail will now fetch the management token from by making
a request to the Cloudflare API using the cert.pem (acquired from
cloudflared login).
Refactored some of the credentials code into it's own package as
to allow for easier use between subcommands outside of
`cloudflared tunnel`.
This PR fixes some long standing bugs in the windows update
paths. We previously did not surface the errors at all leading to
this function failing silently.
This PR:
1. Now returns the ExitError if the bat run for update fails.
2. Fixes the errors surfaced by that return:
a. The batch file doesnt play well with spaces. This is fixed by
using PROGRA~1/2 which are aliases windows uses.
b. The existing script also seemed to be irregular about where batch
files were put and looked for. This is also fixed in this script.
Going forward, the only protocols supported will be QUIC and HTTP2,
defaulting to QUIC for "auto". Selecting h2mux protocol will be forcibly
upgraded to http2 internally.
Named Tunnels can exist without Ingress rules (They would default to
8080). Moreover, having this check also prevents warp tunnels from
starting since they do not need ingress rules.
This PR starts a separate server for proxy-dns if the configuration is
available. This fixes a problem on cloudflared not starting in proxy-dns
mode if the url flag (which isn't necessary for proxy-dns) is not
provided. Note: This is still being supported for legacy reasons and
since proxy-dns is not a tunnel and should not be part of the
cloudflared tunnel group of commands.
This PR does two things:
It changes how we fallback to a lower protocol: The current state
is to try connecting with a protocol. If it fails, fall back to a
lower protocol. And try connecting with that and so on. With this PR,
if we fail to connect with a protocol, we will try to connect to other
edge addresses first. Only if we fail to connect to those will we
fall back to a lower protocol.
It fixes a behaviour where if we fail to connect to an edge addr,
we keep re-trying the same address over and over again.
This PR now switches between edge addresses on subsequent connecton attempts.
Note that through these switches, it still respects the backoff time.
(We are connecting to a different edge, but this helps to not bombard an edge
address with connect requests if a particular edge addresses stops working).
Before this change when running cloudflare tunnel command without any
subcommand and without any additional flag, we would spin up a
QuickTunnel.
This is really a strange behaviour because we can easily create unwanted
tunnels and results in bad user experience.
This also has the side effect on putting more burden in our services
that are probably just mistakes.
This commit fixes that by requiring user to specify the url command
flag.
Running cloudflared tunnel alone will result in an error message
instead.
cloudflared shows possible directories for config files to be present if
it doesn't see one when starting up. For remotely configured files, it
may not be necessary to have a config file present. This PR looks to see
if a token flag was provided, and if yes, does not log this message.
This commit makes cloudflared use the API token provided during login
instead of service key.
In addition, it eliminates some of the old formats since those are
legacy and we only support cloudflared versions newer than 6 months.

This PR is made using suggestion from #574. The pros for this config is that it will work both Windows and Linux (tested), as well as in VSCode, which normally can't be done with the current generated ssh config (refers to #734)
Remove send and return methods from Funnel interface. Users of Funnel can provide their own send and return methods without wrapper to comply with the interface.
Move packet router to ingress package to avoid circular dependency
Previously allowing the reconnect signal forcibly close the connection
caused a race condition on which error was returned by the errgroup
in the tunnel connection. Allowing the signal to return and provide
a context cancel to the connection provides a safer shutdown of the
tunnel for this test-only scenario.
For WARP routing the defaults for these new settings are 5 seconds for connect timeout and 30 seconds for keep-alive timeout. These values can be configured either remotely or locally. Local config lives under "warp-routing" section in config.yaml.
For websocket-based proxy, the defaults come from originConfig settings (either global or per-service) and use the same defaults as HTTP proxying.
This addresses https://security.snyk.io/vuln/SNYK-GOLANG-GOPKGINYAMLV3-2841557
by updating yaml v3 to latest version.
It also stops using yaml v2 directly (we were using both v2 and v3 mixed).
We still rely on yaml v2 indirectly, via urfave cli, though.
Note that the security vulnerability does not affect v2.
Ingress validate currently validates config from a file. This PR adds a
new --json/-j flag to provide the ingress/config data as a plaintext
command line argument.
This is a cherry-pick of 157f5d1412
followed by build/CI changes so that amd64/linux FIPS compliance is
provided by new/separate binaries/artifacts/packages.
The reasoning being that FIPS compliance places excessive requirements
in the encryption algorithms used for regular users that do not care
about that. This can cause cloudflared to reject HTTPS origins that
would otherwise be accepted without FIPS checks.
This way, by having separate binaries, existing ones remain as they
were, and only FIPS-needy users will opt-in to the new FIPS binaries.
