John Maguire 8d8ae0f744 Disable DNS registration on the Windows tunnel adapter (#1914)
On a domain-joined Windows host the DNS Client registers every adapter's
addresses under the host name in AD DNS when "Register this connection's
addresses in DNS" is on, which is the default for a new adapter. When the
Nebula adapter registers, LAN clients that are not on the overlay resolve
the host name to its overlay IP and RDP, SMB and PowerShell Remoting to it
fail intermittently, with nothing pointing at the tunnel as the cause.
Windows registers on address assignment, periodically, and on every
ipconfig /registerdns.

Right after the wintun adapter is created and before Activate assigns any
address, write RegistrationEnabled=0, DisableDynamicUpdate=1 and
MaxNumberOfAddressesToRegister=0 under both the Tcpip and Tcpip6
Parameters\Interfaces\{GUID} keys. The adapter checkbox alone has proven
insufficient in practice, as has disabling dynamic updates alone, so all
three are set, matching what Tailscale and NetBird do. A failure to write
the keys is logged as a warning and does not fail adapter creation.

Matt Richardson f9b0853476 Attach a pending handshake's RemoteList when the handshake starts (#1909)
StartHandshake returned a hostinfo with no RemoteList; handleOutbound attached
one lazily on its first tick. Anything that touched the pending host before
then, notably create-tunnel -address, dereferenced nil and took the daemon
down. StartHandshake now attaches the lighthouse's list as it builds the
hostinfo. To keep the surrounding locking sound, a lighthouse now resolves a
punch target before taking the querier's RemoteList lock, and closeTunnel
deletes the host and evicts its RemoteList under a single hostmap write lock so
a completing handshake cannot land in between. The lock order, now documented
on the handshake manager mutex, is hostmap, then handshake manager, then
lighthouse, then RemoteList; no RemoteList lock is ever held across a hostmap
lookup.

Jack Doan 7cfa47d569 tweaks to error handling in iputil.IPv6FindUpperProtocol (#1893) 2026-09-22 15:45:01 -05:00
Caleb JasikandNate Brown e20569ce51 Let the darwin tun adopt an fd the host already configured (#1890)
newTunFromFd was a stub on darwin, so an embedder handed a utun by the OS had
no way to use it. A darwin network extension is given exactly that:
NEPacketTunnelProvider creates the device and applies addressing, mtu and
routes from its network settings, and a sandboxed extension cannot change them
afterwards. Adopting that fd means everything about moving packets is shared
with newTun and only the setup differs, so the tun tracks whether the host owns
it and leaves the system routing table and interface config alone when it does.

Caleb JasikandNate Brown 9651ffdb0d Cancel the context when Main hands back no Control (#1889)
The goroutines Main starts stop only when its context does, and only a caller
holding the Control can arrange that. Cancelling solely on error left a config
test, which returns no Control and no error, with the lighthouse query worker
and a hostname resolver per dns named static host running for the life of the
process. Every embedder that validates a config in process rather than by
exec'ing pays for that on each config load, dnclient and the apple clients
included.

Wade Simmons 3fc627e08d Add script to backport a merged PR to a release branch (#1851)
* Add script to backport a merged PR to a release branch

.github/backport.sh cherry-picks a merged PR's commit onto a release
branch and opens a backport PR mirroring the shape of #1842.

- Infers the target release from the PR's milestone (v1.12.0 -> release-1.11);
  an explicit target-version argument overrides it.
- Requires a clean working tree (untracked files allowed) before starting.
- Prompts with the exact push and gh pr create commands before running them.
- Sets the new PR's milestone to the highest open v<target>.* milestone.
- Removes the needs-backport label from the original PR once the backport opens.
- Supports --continue to resume after resolving cherry-pick conflicts.

* cleanup

* just fetch all of origin

We need to ensure we have MERGE_SHA available too

Wade Simmons 9c5d701648 Support native Golang "fips140" mode (#1696)
Add support for the "fips140" mode of Go:

- https://go.dev/doc/security/fips140
- https://csrc.nist.gov/projects/cryptographic-module-validation-program/certificate/5247

You can build with `make fips140`, see the README changes for more info.

Some differences from the boringcrypto builds:

- We switch to using `go:linkname crypto/tls.aeadAESGCMTLS13`, which gives us the fips implementation for both `boringcrypto` and `fips140` modes. This means we also no longer need `-checklinkname=0`
- Go native `fips140` doesn't need CGO_ENABLED=1
- We decide if we should use the fips140 GCM at runtime, if `fips140.Enabled()` is true. If you use the `make release-fips140`, we build with build tag `fips140enforce` which ensures the binary is running with fips140 enabled and that only P256 / AES-GCM is being used. If you don't want this enforce mode, you can build without the build tag.

Jay R. WrenandClaude 28d82f7b8a Drop dependency on github.com/cyberdelia/go-metrics-graphite (#1832)
The go-metrics-graphite package has been unmaintained for 10+ years,
which is a packaging and supply-chain concern for downstream
distributors (see #1831). Nebula only used its Config struct and Once()
entrypoint, so inline just those (~65 lines) into a local graphite.go,
preserving the upstream BSD-2-Clause copyright notice, and remove the
dependency.

Fixes #1831

* use stdlib maps.Values

This has been in stdlib since go1.23, no need to use golang.org/x/exp
anymore just for this:

- https://pkg.go.dev/maps#Values

* use slices.AppendSeq to match old behavior
