Dean Sundquist 5c5d1dc161 TUN-8629: Cloudflared update on Windows requires running it twice to update 2024-09-16 18:31:57 +00:00
Devin Carr cd8cb47866 TUN-8632: Delay checking auto-update by the provided frequency
Delaying the auto-update check timer to start after one full round of
the provided frequency reduces the chance of upgrading immediately
after starting.

Devin Carr 2484df1f81 TUN-8630: Check checksum of downloaded binary to compare to current for auto-updating
In the rare case that the updater downloads the same binary (validated via checksum)
we want to make sure that the updater does not attempt to upgrade and restart the cloudflared
process. The binaries are equivalent and this would provide no value.

However, we are covering this case because there was an errant deployment of cloudflared
that reported itself as an older version and was then stuck in an infinite loop
attempting to upgrade to the latest version which didn't exist. By making sure that
the binary is different ensures that the upgrade will be attempted and cloudflared
will be restarted to run the new version.

This change only affects cloudflared tunnels running with default settings or
`--no-autoupdate=false` which allows cloudflared to auto-update itself in-place. Most
distributions that handle package management at the operating system level are
not affected by this change.

Devin Carr eb2e4349e8 TUN-8415: Refactor capnp rpc into a single module
Combines the tunnelrpc and quic/schema capnp files into the same module.

To help reduce future issues with capnp id generation, capnpids are
provided in the capnp files from the existing capnp struct ids generated
in the go files.

Reduces the overall interface of the Capnp methods to the rest of
the code by providing an interface that will handle the quic protocol
selection.

Introduces a new `rpc-timeout` config that will allow all of the
SessionManager and ConfigurationManager RPC requests to have a timeout.
The timeout for these values is set to 5 seconds as non of these operations
for the managers should take a long time to complete.

Removed the RPC-specific logger as it never provided good debugging value
as the RPC method names were not visible in the logs.

João "Pisco" Fernandes 76badfa01b TUN-8236: Add write timeout to quic and tcp connections
## Summary
To prevent bad eyeballs and severs to be able to exhaust the quic
control flows we are adding the possibility of having a timeout
for a write operation to be acknowledged. This will prevent hanging
connections from exhausting the quic control flows, creating a DDoS.

This is to be consistent with the 0-based indexing on the log lines when
proxying requests.

João "Pisco" Fernandes 541c63d737 TUN-7824: Fix usage of systemctl status to detect which services are installed
## Summary
To determine which services were installed, cloudflared, was using the command
`systemctl status` this command gives an error if the service is installed
but isn't running, which makes the `uninstall services` command report wrongly
the services not installed. Therefore, this commit adapts it to use the
`systemctl list-units` command combined with a grep to find which services are
installed and need to be removed.

João "Pisco" Fernandes 958b6f1d24 TUN-7813: Improve tunnel delete command to use cascade delete
## Summary
Previously the force flag in the tunnel delete command was only explicitly deleting the
connections of a tunnel. Therefore, we are changing it to use the cascade query parameter
supported by the API. That parameter will delegate to the server the deletion of the tunnel
dependencies implicitly instead of the client doing it explicitly. This means that not only
the connections will get deleted, but also the tunnel routes, ensuring that no dependencies
are left without a non-deleted tunnel.

João Oliveirinha 6d1d91d9f9 TUN-7787: Refactor cloudflared to use new route endpoints based on route IDs
This commits makes sure that cloudflared starts using the new API
endpoints for managing routes.

Additionally, the delete route operation still allows deleting by CIDR
and VNet but it is being marked as deprecated in favor of specifying the
route ID.

The goal of this change is to make it simpler for the user to delete
routes without specifying Vnet.

João "Pisco" Fernandes af3a66d60e TUN-7597: Add flag to disable auto-update services to be installed
Summary:
This commit adds a new flag "no-update-service" to the `cloudflared service install` command.

Previously, when installing cloudflared as a linux service it would always get auto-updates, now with this new flag it is possible to disable the auto updates of the service.

This flag allows to define whether we want cloudflared service to **perform auto updates or not**.
For **systemd this is done by removing the installation of the update service and timer**, for **sysv** this is done by **setting the cloudflared autoupdate flag**.

João Oliveirinha 0c8bc56930 TUN-7575: Add option to disable PTMU discovery over QUIC
This commit implements the option to disable PTMU discovery for QUIC
connections.
QUIC finds the PMTU during startup by increasing Ping packet frames
until Ping responses are not received anymore, and it seems to stick
with that PMTU forever.

This is no problem if the PTMU doesn't change over time, but if it does
it may case packet drops.
We add this hidden flag for debugging purposes in such situations as a
quick way to validate if problems that are being seen can be solved by
reducing the packet size to the edge.

Note however, that this option may impact UDP proxying since we expect
being able to send UDP packets of 1280 bytes over QUIC.
So, this option should not be used when tunnel is being used for UDP
proxying.

Devin Carr 8a3eade6d3 TUN-7553: Add flag to enable management diagnostic services
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.

Devin Carr 2b4815a9f5 TUN-7543: Add --debug-stream flag to cloudflared access ssh
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.

Sudarsan Reddy 1abd22ef0a TUN-7480: Added a timeout for unregisterUDP.
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.
