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.
- cfsetup now has a build command `github-release-pkgs` to release linux
and msi packages to github.
- github_message.py now has an option to upload all assets in a provided
directory.
Jitter is important to avoid every cloudflared in the world trying to
reconnect at t=1, 2, 4, etc. That could overwhelm the backend. But
if each cloudflared randomly waits for up to 2, then up to 4, then up
to 8 etc, then the retries get spread out evenly across time.
On average, wait times should be the same (e.g. instead of waiting for
exactly 1 second, cloudflared will wait betweeen 0 and 2 seconds).
This is the "Full Jitter" algorithm from https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/
