## Summary
This commit refactors some of the flags of cloudflared to their own module, so that they can be used across the code without requiring to literal strings which are much more error prone.
Closes TUN-8914
## Summary
This commit introduces a new command line flag, `--max-active-flows`, which allows overriding the remote configuration for the maximum number of active flows.
The flag can be used with the `run` command, like `cloudflared tunnel --no-autoupdate run --token <TUNNEL_TOKEN> --max-active-flows 50000`, or set via an environment variable `TUNNEL_MAX_ACTIVE_FLOWS`.
Note that locally-set values always take precedence over remote settings, even if the tunnel is remotely managed.
Closes TUN-8914
## Summary
When the FIPS compliance was achieved with HTTP/2 Transport the technology at the time wasn't available or certified to be used in tandem with Post-Quantum encryption. Nowadays, that is possible, thus, we can also remove this restriction from Cloudflared.
Closes TUN-8857
## Summary
Nowadays, Cloudflared only supports X25519Kyber768Draft00 (0x6399,25497) but older versions may use different preferences.
For FIPS compliance we are required to use P256Kyber768Draft00 (0xfe32,65074) which is supported in our internal fork of [Go-Boring-1.22.10](https://bitbucket.cfdata.org/projects/PLAT/repos/goboring/browse?at=refs/heads/go-boring/1.22.10 "Follow link").
In the near future, Go will support by default the X25519MLKEM768 (0x11ec,4588) given this we may drop the usage of our public fork of GO.
To summarise:
* Cloudflared FIPS: QUIC_CURVE_PREFERENCES=65074
* Cloudflared non-FIPS: QUIC_CURVE_PREFERENCES=4588
Closes TUN-8855
## Summary
This commit renames the public variable that identifies the metadata key and value for the ConnectResponse structure when the flow was rate limited.
Closes TUN-8904
## Summary
cloudflared access login and cloudflared access curl fails when the Access application has warp_as_auth enabled.
This bug originates from a 4 year old inconsistency where tokens signed by the nginx-fl-access module include 'aud' as a string, while tokens signed by the access authentication worker include 'aud' as an array of strings.
When the new(ish) feature warp_as_auth is enabled for the app, the fl module signs the token as opposed to the worker like usually.
I'm going to bring this up to the Access team, and try to figure out a way to consolidate this discrepancy without breaking behaviour.
Meanwhile we have this [CUSTESC ](https://jira.cfdata.org/browse/CUSTESC-47987), so I'm making cloudflared more lenient by accepting both []string and string in the token 'aud' field.
Tested this by compiling and running cloudflared access curls to my domains
Closes AUTH-6633
## Summary
Session is the concept used for UDP flows. Therefore, to make
the session limiter ambiguous for both TCP and UDP, this commit
renames it to flow limiter.
Closes TUN-8861
## Summary
In order to make cloudflared behavior more predictable and
prevent an exhaustion of resources, we have decided to add
session limits that can be configured by the user. This commit
adds the session limiter to the HTTP/TCP handling path.
For now the limiter is set to run only in unlimited mode.
## Summary
In order to make cloudflared behavior more predictable and
prevent an exhaustion of resources, we have decided to add
session limits that can be configured by the user. This first
commit introduces the session limiter and adds it to the UDP
handling path. For now the limiter is set to run only in
unlimited mode.
## Summary
During the renewal of the certificates used to sign the macOS binaries and package,
we faced an issue with the new certificates requiring a specific certification authority
that wasn't available in the keychain of the mac agents. Therefore, this commit adds
an import step that will ensure that the Certificate Authority, usually fetched from
https://www.apple.com/certificateauthority/ is imported into the keychain to validate
the Developer Certificates.
Closes TUN-8900
## Summary
To improve our code, this commit adds a linter that will start
checking for issues from this commit onwards, also forcing
issues to be fixed on the file changed and not only on the changes
themselves. This should help improve our code quality overtime.
Closes TUN-8866
Support rolling out the `support_datagram_v3` feature via remote feature rollout (DNS TXT record) with `dv3` key.
Consolidated some of the feature evaluation code into the features module to simplify the lookup of available features at runtime.
Reduced complexity for management logs feature lookup since it's a default feature.
Closes TUN-8807
## Summary
Ubuntu has released a new LTS version, and there are people starting to use it, this makes
our installation recommendation, that automatically detecs the release flavor, to fail for
Noble users. Therefore, this commit adds this new version to our release packages.
It also adds an `any` package so that we can update our documentation to use it since
we are using the same binaries across all debian flavors, so there is no reason to keep
adding more release flavors when we can just take advantage of the `any` release flavor
like other repositories do.
When closing a session, there are two possible signals that will occur,
one from the outside, indicating that the session is idle and needs to
be closed, and the internal error condition that will be unblocked
with a net.ErrClosed when the connection underneath is closed. Both of
these routines write to the session's closeChan.
Once the reader for the closeChan reads one value, it will immediately
return. This means that the channel is a one-shot and one of the two
writers will get stuck unless the size of the channel is increased to
accomodate for the second write to the channel.
With the channel size increased to two, the second writer (whichever
loses the race to write) will now be unblocked to end their go routine
and return.
Closes TUN-8817
## Summary
Adds a new CLI subcommand, under the tunnel command, the `diag`. This command has as function the automatic collection of different data points, such as, logs, metrics, network information, system information, tunnel state, and runtime information which will be written to a single zip file.
Closes TUN-8724
## Summary
Change the system information collector and respective http handler so that it always returns a JSON.
