Nuno Diegues 628545d229 TUN-5600: Close QUIC transports as soon as possible while respecting graceful shutdown
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.

Nuno Diegues 70e675f42c TUN-5551: Reintroduce FIPS compliance for linux amd64 now as separate binaries
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.

Fix for Issue #501: Unexpected User-agent insertion when tunneling http request

Benoit Plessis b88e0bc8f8 Fix for Issue #501: Unexpected User-agent insertion when tunneling http request
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.

Nuno Diegues 1ee540a166 TUN-5368: Log connection issues with LogLevel that depends on tunnel state
Connections from cloudflared to Cloudflare edge are long lived and may
break over time. That is expected for many reasons (ranging from network
conditions to operations within Cloudflare edge). Hence, logging that as
Error feels too strong and leads to users being concerned that something
is failing when it is actually expected.

With this change, we wrap logging about connection issues to be aware
of the tunnel state:
 - if the tunnel has no connections active, we log as error
 - otherwise we log as warning

Sudarsan Reddy bccf4a63dc UN-5213: Increase MaxStreams value for QUIC transport
The default max streams value of 100 is rather small when subject to
high load in terms of connecting QUIC with streams faster than it can
create new ones. This high value allows for more throughput.

Sudarsan Reddy 8f3526289a TUN-4701: Split Proxy into ProxyHTTP and ProxyTCP

Sudarsan Reddy d678584d89 TUN-4655: ingress.StreamBasedProxy.EstablishConnection takes dest input
This change extracts the need for EstablishConnection to know about a

http.Response from EstablishConnection's responsibilities.

Sudarsan Reddy f1b57526b3 TUN-4626: Proxy non-stream based origin websockets with http Roundtrip.
Reuses HTTPProxy's Roundtrip method to directly proxy websockets from
eyeball clients (determined by websocket type and ingress not being
connection oriented , i.e. Not ssh or smb for example) to proxy
websocket traffic.

Igor Postelnik 3ad99b241c TUN-4168: Transparently proxy websocket connections using stdlib HTTP client instead of gorilla/websocket; move websocket client code into carrier package since it's only used by access subcommands now (#345). 2021-04-07 16:25:46 +00:00
Igor Postelnik 8ca0d86c85 TUN-3863: Consolidate header handling logic in the connection package; move headers definitions from h2mux to packages that manage them; cleanup header conversions
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.

- Consolidate all code dealing with token generation and transfer to a single cohesive package.
