Ryan HuberandClaude Opus 5.5 21a7f1b711 overlay/darwin: read the utun with recvmsg_x
tunQueue.Read now takes up to 64 queued packets with one recvmsg_x through
internal/msgx, each into its own 64KiB slot of a buffer allocated once per
queue, and falls back to the readv drain for good when recvmsg_x is refused
or returns a batch intact msghdr_x entries can't produce, or for one Read on
a transient error. Ported from the pipeline bench build's tunRecvX, minus its
env toggle and stats.

With 64 pending packets on the utun this is the remaining send gain: on an
M2 mini, one stream, pipeline + 64 pending reads 4.9 Gbps with recvmsg_x and
2.6 with the readv loop, the same as this branch before this commit.

Ryan HuberandClaude Opus 5.5 64bec56404 darwin: pipeline listenIn's sends so write batches can form
On darwin, listenIn encrypts into one SendBatch while a sender goroutine
writes the other (batch.SendPipeline). The sender takes whatever built up
during its last write, so writes overlap tun reads and packets queued
behind a write leave in one WriteBatch, which a connected socket sends as
one sendmsg_x. Two batches bound memory; a full producer waits for the
swap rather than dropping. One producer and one sender keep per-peer order
equal to message-counter order.

Everywhere else the branch is a false constant and listenIn is unchanged.
-tags send_pipeline builds the pipeline on any platform, so its tests and
the e2e suite can run through it on linux.

Ryan HuberandClaude Opus 5.5 81f991f1fd overlay/darwin: batch tun writes with sendmsg_x, drain reads, 64 pending packets
tun.WriteBatch writes up to 64 packets per sendmsg_x on the utun control
socket, and Passthrough.Flush hands its lane to it whole through the new
tio.BatchWriter (Caleb Jasik's #1896). Only the darwin tun implements
BatchWriter, so every other platform keeps one Write per packet.

tunQueue.Read drains every packet already queued on the utun, up to 64,
so a burst reaches the send batch together.

xnu lets only one packet wait on a utun control socket by default, so
each read found one packet. The tun now raises
UTUN_OPT_MAX_PENDING_PACKETS to 64, growing SO_RCVBUF to hold that many
packets first; on failure it logs and keeps xnu's default.

Tests: #1896's WriteBatch tests over sendmsg_x and the writev fallback,
the drain tests, the pending-packet setsockopts, and #1906's framing and
zero-alloc Read/Write tests.

Ryan HuberandClaude Opus 5.5 21075ba32e udp/darwin: batch receives and connected-socket sends with recvmsg_x/sendmsg_x
internal/msgx is the one copy of xnu's private batched socket calls: the
msghdr_x layout, Send/Recv through the raw syscall (EINTR retried) and
Unsupported for the errnos a kernel or sandbox refuses them with.

Every socket the listener owns reads with recvmsg_x: the listener and each
connected socket run their own reader goroutine, and hand whole batches to
ListenOut over a channel. ListenOut runs the EncReader over a batch and
flushes once, so the reader stays single-threaded without a lock that
readers contend on, and the next recvmsg_x overlaps the decrypt of the last
batch. Batch buffers (64 x MTU) come from a per-listener free list that
keeps up to 11; a reader takes one only while its socket is readable, so
idle connected sockets hold none. A batch with a header intact msghdr_x
entries can't produce, or ENOSYS/EPERM/EOPNOTSUPP, switches every reader to
one datagram per read for good.

Connected sockets send runs with sendmsg_x, which xnu batches through the
stack on a connected socket. EAGAIN/ENOBUFS keep #1901's single-datagram
stall handling; a refused sendmsg_x retries the datagram with write and
turns sendmsg_x off once that goes through.

The connected-socket knobs lose their NEBULA_CONNSOCK* environment
overrides and keep #1901's defaults.

Based on Caleb Jasik's #1895 (recvmsg_x) and #1897 (sendmsg_x), and Jack
Doan's internal/msgx shape from #1898.

Caleb JasikandClaude Opus 5.5 37032a22bf udp/darwin: send to busy established peers on connected sockets
On darwin an unconnected sendto runs the address and MAC policy checks
and the EndpointSecurity send check for every datagram, and while
xprotectd throttles it each send takes about 185us, which caps a
tunnel's upload and, through its ACKs, its download. A connected socket
runs those checks once, at connect, and it is the only UDP send that
reports the interface queue's flow control, as ENOBUFS.

Only the current direct remote of an established tunnel is eligible.
udp.EstablishedPeerConn is an optional Conn interface, implemented on
darwin; establishedRemotes refcounts remotes over the main hostmap and
tells each writer on the first and last reference: handshake completion
adds one, deleting or retiring a hostinfo removes it, SetRemote (roaming,
SetRemoteIfPreferred, control, ssh) moves it. Pending and relayed
hostinfos hold none, and a rehandshake's two hostinfos share one.

An eligible peer that Nebula sends NEBULA_CONNSOCK_RUN (64) datagrams to
within NEBULA_CONNSOCK_WINDOW (1s) gets a connected socket: SO_REUSEPORT,
bound to the source address the listener's route to the peer picks on
the listener's port, carrying the listener's IP_BOUND_IF. The peer sees
the same address and port as from the listener, and the socket's reader
delivers through the listener's reader. The listener itself never sets
SO_REUSEPORT (listen routines still do), so no other uid can bind the
port; with a specific listen.host and no routines connected sockets stay
off, since sharing an exact address needs SO_REUSEPORT on both.

All routines listening on one address share one set of connected
sockets: at most NEBULA_CONNSOCKS (8), one per peer, with opens from a
bucket that refills one per NEBULA_CONNSOCK_OPEN_EVERY (1s). A socket
closes when its peer stops being eligible, after NEBULA_CONNSOCK_IDLE
(30s) without traffic, on Rebind (of every routine) and Close, and on an
error that means the connected path is gone. Closing never runs under
the hostmap's or the eligibility lock; the peer can't reopen until the
close finishes. A send that gets ENOBUFS or EAGAIN waits within one
10ms budget shared by every writer since the last send that went
through, then drops; nothing waits in the netpoller without a deadline.
When nothing is eligible or open, a send costs one atomic load before
the listener path.

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

Jack Doan 19e04db115 disable offloads by default for first release (#1858) 2026-08-24 12:33:08 -05:00
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
