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 changes fixes a bug where cloudflared was not propagating errors
when proxying the body of an HTTP request.
In a situation where we already sent HTTP status code, the eyeball would
see the request as sucessfully when in fact it wasn't.
To solve this, we need to guarantee that we produce HTTP RST_STREAM
frames.
This change was applied to both http2 and quic transports.
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 PR temporarily disables the xcrun notarize-app feature since this
is soemthing we've historically had broken. However, what changed now is
we set -e for the mac os scripts. We'll need to remove this to unblock
mac builds.
We could spend time as part of https://jira.cfdata.org/browse/TUN-5789
to look into this.
We previously always preferred region2 as the first region to connect
to if both the regions cloudflared connects to have the same number of
availabe addresses. This change randomises that choice. The first
connection, conn index: 0, can now either connect to region 1 or region
2.
More importantly, conn 0 and 2 and 1 and 3 need not belong to the same
region.
