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.
Will no longer provide full hostname with path from provided
`--hostname` flag for cloudflared access to the Host header field.
This addresses certain issues caught from a security fix in go
1.19.11 and 1.20.6 in the net/http URL parsing.
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**.
h2mux is already deprecated and will be eventually removed, in the meantime,
the compression tests cause flaky failures. Removing them and the brotli
code slims down our binaries and dependencies on CGO.
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.
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.
In the streambased origin proxy flow (example ssh over access), there is
a chance when we do not flush on http.ResponseWriter writes. This PR
guarantees that the response writer passed to proxy stream has a flusher
embedded after writes. This means we write much more often back to the
ResponseWriter and are not waiting. Note, this is only something we do
when proxyHTTP-ing to a StreamBasedOriginProxy because we do not want to
have situations where we are not sending information that is needed by
the other side (eyeball).
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.
