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.
* `max-fetch-size` can now be set up in the config YAML
* we no longer pass that to filter commands that filter by name
* flag changed to signed int since altsrc does not support UInt flags
* we now look up each non UUID (to convert it to a UUID) when needed, separately
This can be useful/important for accounts with many tunnels that exceed
the 1000 default page size.
There are various tunnel subcommands that use listing underneath, so we make
that flag a tunnel one, rather than adding it to each subcommand.
This maximum grace period will be honored by Cloudflare edge such that
either side will close the connection after unregistration at most
by this time (3min as of this commit):
- If the connection is unused, it is already closed as soon as possible.
- If the connection is still used, it is closed on the cloudflared configured grace-period.
Even if cloudflared does not close the connection by the grace-period time,
the edge will do so.
All header transformation code from h2mux has been consolidated in the connection package since it's used by both h2mux and http2 logic.
Exported headers used by proxying between edge and cloudflared so then can be shared by tunnel service on the edge.
Moved access-related headers to corresponding packages that have the code that sets/uses these headers.
Removed tunnel hostname tracking from h2mux since it wasn't used by anything. We will continue to set the tunnel hostname header from the edge for backward compatibilty, but it's no longer used by cloudflared.
Move bastion-related logic into carrier package, untangled dependencies between carrier, origin, and websocket packages.
This change has two parts:
1. Update to newer version of the urfave/cli fork that correctly sets flag value along the context hierarchy while respecting config file overide behavior of the most specific instance of the flag.
2. Redefine --credentials-file flag so that create and delete subcommand don't use value from the config file.
- Move packages the provide generic functionality (such as config) from `cmd` subtree to top level.
- Remove all dependencies on `cmd` subtree from top level packages.
- Consolidate all code dealing with token generation and transfer to a single cohesive package.
- extracted ResponseWriter from proxyConnection
- added bastion tests over websocket
- removed HTTPResp()
- added some docstrings
- Renamed some ingress clients as proxies
- renamed instances of client to proxy in connection and origin
- Stream no longer takes a context and logger.Service
