This parameterizes relevant component tests by transport protocol
where applicable.
The motivation is to have coverage for (graceful or not) shutdown
that was broken in QUIC. That logic (as well as reconnect) is
different depending on the transport, so we should have it
parameterized. In fact, the test is failing for QUIC (and passing
for others) right now, which is expected until we roll out some
edge fixes for QUIC. So we could have caught this earlier on.
This adds various bug fixes when investigating why QUIC transports were
not being unregistered when they should (and only when the graceful shutdown
started).
Most of these bug fixes are making the QUIC transport implementation closer
to its HTTP2 counterpart:
- ServeControlStream is now a blocking function (it's up to the transport to handle that)
- QUIC transport then handles the control plane as part of its Serve, thus waiting for it on shutdown
- QUIC transport now returns "non recoverable" for connections with similar semantics to HTTP2 and H2mux
- QUIC transport no longer has a loop around its Serve logic that retries connections on its own (that logic is upstream)
This does a few fixes to make sure that the QUICConnection returns from
Serve when the context is cancelled.
QUIC transport now behaves like other transports: closes as soon as there
is no traffic, or at most by grace-period. Note that we do not wait for
UDP traffic since that's connectionless by design.
This way we will force the adoption of FIPS compliant cloudflared without having
to handle the transition for systems that already have it installed (since we
were previously using new artifacts with fips suffix) nor without having to
segregate the resulting binary name (since we were always generating a binary
just called cloudflared from the unpacked debian archive to avoid having to change
any automation that assumes the binary to be called just that).
This changes existing Makefile targets to make it obvious that they are
used to publish debian packages for internal Cloudflare usage. Those are
now FIPS compliant, with no alternative provided. This only affects amd64
builds (and we only publish internally for Linux).
This new Makefile target is used by all internal builds (including nightly
that is used for e2e tests).
Note that this Makefile target renames the artifact to be just `cloudflared`
so that this is used "as is" internally, without expecting people to opt-in
to the new `cloudflared-fips` package (as we are giving them no alternative).
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.
This reverts commit 157f5d1412.
FIPS compliant binaries (for linux/amd64) are causing HTTPS origins to not
be reachable by cloudflared in certain cases (e.g. with Let's Encrypt certificates).
Origins that are not HTTPS for cloudflared are not affected.
Creates an abstraction over UDP Conn for origin "connection" which can
be useful for future support of complex protocols that may require
changing ports during protocol negotiation (eg. SIP, TFTP)
In addition, it removes a dependency from ingress on connection package.
When building the docker image, this `-dev` suffix is being added to the
cloudflared binary version.
The reason must be that there's some file, which is tracked by git, and
that is modified during that build.
It's not clear which file is it. But, at the same time, it's not clear what
advantage this `-dev` suffix is bringing. So we're simply removing it so that
we generate proper versions (so that our tracking/observability can correctly
aggregate these values).
- Refactors some h2mux specific logic from connection/header.go to connection/h2mux_header.go
- Do the same for the unit tests
- Add a non-h2mux "is control response header" function (we don't need one for the request flow)
- In that new function, do not consider "content-length" as a control header
- Use that function in the non-h2mux flow for response (and it will be used also in origintunneld)
When forwarding an UA-less request to the origin server cloudflared insert the default golang http User-Agent, this is unexpected and can lead to issue.
This simple fix force setting the UA to the empty string when it isn't originaly provided.
